Description of the invention () < Inventory of the invention > The present invention relates to pipe joints, more specifically, it relates to joints that can be inserted into pipes Body • Insert the tube movably along the axis in the body of the joint. The coupling ring of the claw is protruded to be inserted into the outer wall of the pipe. It is embedded in the body of the joint. The inner peripheral surface of the body of the joint and Between the outer peripheral surfaces of the tube, there is provided a pipe joint faced with an elastic ring seal. There are various types of pipe joints used to transport fluids. Here is an example of a conventional pipe joint as shown in Figure 6. In the 80 series joint body, the connection port of the inner tube 42 of the joint body 80 is first fitted into the tip of the coupling ring 82 that can move freely in the axial direction. The coupling ring 82 is formed in a substantially cylindrical shape into which the tube 42 can be inserted. In addition, at the position of the pair of oranges on the inner side of the connection port, a coupling type stopper H 86 which is divided into a plurality of claws 84 on the inner surface is formed in the circumferential direction. The joint 82 is dragged to the exit direction of the splicing port, and is guided to the inner wall guide of the joint body 80. The leading end of each stop piece 86 moves toward the inner side and becomes smaller, so that the claw portion 84 can be inserted into the pipe. On the outer wall, on the side of the restraining piece 86, an inclined surface 88 that is inclined toward the inside of the connection port is formed. In addition, the joint body S0 symmetrical to the first stretch of the restraining piece 86 is formed with a through hole 90 extending in the direction of the worm. Therefore, each of the restraining pieces 86 can protrude out of the through hole 90 or can be released from the tube. The claws of the tube allow the tube to be withdrawn. In addition, when the escort team wrote 82, it was placed on the through-hole wall surface 92 of the opposing connector body 80 to form a convex portion 94 that prevented the expansion of the tab 86 from outward. In addition, 96 is a stopper, which is provided on the outer periphery of the If 86. When the junction 82 moves backward, it can be tightly attached to the inner wall 90a of the through-hole 90 to prevent the movement of the joint 82.

Description of the invention () As for the left end of the joint body 80, a threaded portion 98 for tightening the pipe joint M press (not shown) is provided. In addition, 99 is an elastomer ring, which is made of a rubber material that forms a subject, and is in close contact with the outer bark of the insertion tube and the inner surface of the joint body to prevent the fluid from being pulled. According to the above-described pipe joint, after the pipe 42 is inserted into the joint body 80, the pipe 42 and the joint broken 82 will move in the pulling direction to some extent, so that the claw portion 84 of the joint ring is fitted into the outer wall of the pipe 42; Was pulled out. In addition, the coupling ring 82 is moved in the pulling direction by the joint body 80, and when the inside of the pipe joint becomes high pressure, the elastic ring 99 moved in the pulling direction from the joint body 80 by the high pressure acts to press the coupling. Achieved from 82. Further, the coupling ring 82 is pushed to open the stopper piece 86, and the claw portion 84 is released from the insertion into the tube 42, and the tube 42 is allowed to be withdrawn. However, the shapes of the coupling ring 82 and the joint body 80 as described above are very complicated. Therefore, when manufacturing the pipe joint, if it is formed of plastic, it must have a model with a complicated shape, and there is a problem that the model is difficult to form. In addition, if it is to be formed from a metal material (stainless steel), because of its complicated shape, the stamping process is of course no problem. For example, when M is cut and formed, it is practically impossible. Also, the movement of the joint carrier 82 to the rear end will be blocked. Although M prevents the step difference 96 from being in close contact with the inner wall 90a of the through-hole 90, adding M to prevent it, but because it does not directly prevent the claw portion 84 from fitting into the outer wall of the tube 42 directly at the leading end of the stopping H86 The tube 42 may be greatly deformed. In this way, due to the large deformation at 42, problems such as deterioration of the tightness of the connection with the tube 42 often occur, resistance of the fluid flowing in the tube; t once a big problem, and so on. In addition, when the claw portion 84 is inserted into the tube 42 to such an extent that the insertion portion inserted into the joint body 80 of the coupling ring 82 is excessively reduced in diameter, the coupling ring 82 and the tube 42 may be pulled out integrally. —4 One paper standard is applicable to the Chinese National Standard (CNS) Λ4 present grid (210X297mm): (please read the note $ item on the back before filling this page)

The tilt holder 54 of this embodiment is a metal material formed by stamping (punching), which can be easily manufactured by It. Various specifications, such as strength and durability suitable for use conditions, can also be molded using synthetic resin materials. The following describes the use of pipe joints with the above structure. In the joint body 10, when the tube 42 is inserted from the coupling ring 34 side, the stop H 38 of the tube 4.2M coupling 34 not only resists its elastic force, but also retracts by the outer wall surface of the tube 42 to move while expanding. In addition, the tube 42 system inserts its front end into a predetermined position where the first difference surface 26 provided inside the body 12 of the joint is in close contact * It can not be drawn any more by drawing a little in the drawing direction. In more detail, when the tube 42 is pulled from the insertion position, the tube 42 and the coupling ring 34 move to the rear side, and the leading end sound "> 48 is guided to the inclined inner surface 40, and each stopper piece 38 retracts to the inside and is inserted. The guide 36 shrinks in the radial direction, and the claw portion 46 is embedded in the outer wall of the insertion tube 42 and the tube 42 is installed in the pipe joint. Therefore, when the high pressure inside the joint body 10 is high, the elastomer ring 64 is drawn in the direction of the pipe extraction When moving, the elastic body 64 moves the tilt ring 54 to the direction of the tube extraction. In this way, when the tilt ring 54 moves in the direction of the tube extraction, the tip 48 of the Η 38 is restrained from being narrow on the inclined outer surface 56 and the inclined inner surface Between 40, the action of the vector force as shown in Figure 3 prevents the tip portion 48 of Η38 from sliding back to the inside: 'More specifically, the reaction force acting on the tip portion pressed between the inclined outer surface 56 and the inclined inner surface 40, The reaction force F1 acting on the inclined outer surface 56 is equal to the reaction force F2 acting on the inclined inner surface 40. Therefore, the reaction force F1 acts on the parallel component F3 acting on the inclined outer surface 56 and is equal to the size of the original paper. Use China National Support Rate (CNS) Α4 specifications 210X297mm) (Please read the note item on the back first and then fill in this page) Κ 装.-訂 A7 Β7 Fifth, the invention description () The force F2 acts on the parallel component 40 of the inclined inner surface F4 is greater than F3. 'The component force f: parallel to the component force 3, the component F5 of 4 is obviously greater than the component F3. If the elastomer ring 64 is moved in the tube extraction direction, the stopper 38 is drawn out along the inclined inner surface 40 Move in the direction while retracting the inside, so that the claw portion 46 is inserted into the outer wall of the insertion tube 42 to prevent the extraction of the tube 42. That is, the reaction forces F1, F2 act in the direction of the scorpion line, and the inclined outer surface 56 is more inclined than the inclined inner surface 40. The angle of the larger inclination angle is the reason for the expansion of the diameter inward in the joint body 10. Therefore, the tip 48 of the restraining piece that moves inward is closely connected to the inner periphery of the inclined outer surface 56 and extends out of the pipe extraction direction. The circumferential stopper 68 prevents the stopper piece 38 from retracting above the predetermined position. This prevents the tube 42 from becoming larger than the predetermined level, preventing the deterioration of the elastomer seal when the tube 42 is connected, and preventing the flow in the tube 42 Increased fluid resistance, etc. In addition, the claw 46 can be prevented from being embedded The pipe 42 is more than necessary, so that the insertion portion 36 inserted into the joint body of the joint 34 is excessively reduced in diameter and prevents the joint 34 from being pulled out together with the pipe 42. Secondly, the assembled pipe 42 is removed from the joint 10 When opened, only the coupling ring 34 is pushed into the joint body 10, and the inclined surface 56 of the inclined shaft 54 is tightly connected to the end surface 58 of the front end 48 of the stop H 38, so that the stop piece 38 can return to the outside. The release claw 46 The outer wall of the tube 42 is inserted so that the tube 42 can be detached. (Second embodiment) The following describes the second embodiment based on Fig. 4 and Fig. 5. However, if the same parts as the first embodiment are used, the first embodiment is used For example, the same symbols are omitted, and the explanation is omitted. The part different from the first embodiment is the shape of the stopper 72 and the inclined ring 74 formed on the inner wall of the guide cylinder 70. The stopper 72 is attached to the inner wall of the guide cylinder portion of the joint body 10 and is in close contact with the outer periphery 76 of the slant 74. In order to prevent the slant 74 from moving in the direction of tube extraction beyond the paper standard, the Chinese national rate is used. ) Eight 4 specifications (210 father 297 male ||) I ----- r-installed 丨 (Please read the note $ item on the back and then fill in this page) Order t-=-1 --- Central Ministry of Economic Affairs Printed 3u ^ 427 a7 __B7_ by the Bureau of Employee Consumer Cooperatives V. Description of the invention () ~~ (please read the note ^^ on the back of t * before filling in this page) at the predetermined position Μ, forming a step difference. In this way, by using the movement of the elastomer ring 64, the tilting glass 74 is pressed, and the tilting movement of the tilting 74 causes the stop ring 34 to move beyond the predetermined position M in the extraction direction, and prevents the system 38 from retracting above the predetermined inside . In addition, the inclined ring 74 of this embodiment is also formed by pressing a gold hurricane material, and the peripheral edge 76 is extended out of the direction of the tube extraction, which is most suitable for preventing the deformation of the inclined ring 54 and indeed preventing The tilt camera 74 moves beyond the predetermined position M in the extraction direction of the tube 42. As for the guide cylinder portion 70, a step 78 is formed near the side. This step prevents the coupling ring 34 from being pulled out.
