Description

Ready-package hose

Technical Field

The invention belongs to the field of connector devices, and particularly relates to a quick-assembly hose connecting device with a lining, which is used for connecting a hose to a fluid conveying pipeline.

Background

Because of their flexibility, repeated flexibility, resistance to bending, tensile strength, and lateral pressure, and low cost, hoses are often used in fluid piping systems to transport fluids.

In the use process of the hose, the length of the hose is not enough, and the two hoses are required to be connected by adopting the connecting device, but the hose is easy to bend and deform under stress, so that the tightness of the hose and the pipe joint of the connecting device is poor, and the leakage phenomenon is often generated.

Disclosure of Invention

In order to ensure the connection effect between the hoses and improve the connection strength between the hoses, the invention provides a quick-assembly hose with a stainless steel pipe sleeve arranged at the end part of the hose.

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a ready-package hose, includes the coupling and sets up two-stage die cavity around in the coupling, and the big internal diameter die cavity of front side has set gradually the sleeve pipe and has fixed the hose body between sleeve pipe and coupling, and the tip is provided with to the spacing boss of hose body axial behind the sleeve pipe, and the little internal diameter die cavity of rear side is right the boss axial is spacing, sleeve pipe and coupling between still be provided with the sealing washer, the front end exit department of coupling is provided with the clamping ring for the shutoff, big internal diameter die cavity inner wall seted up the type groove, the annular in be provided with the anticreep shell fragment that is certain contained angle with the axial.

The quick-assembly hose is characterized in that threads are arranged outside a pipe joint of the quick-assembly hose.

The sleeve of the quick-assembly hose is made of stainless steel.

The invention has the beneficial effects that: when the flexible pipe body is inserted into the pipe joint, the outer wall of the flexible pipe body is contacted with the sealing ring inside the pipe joint to form a sealing surface, and the anti-falling elastic sheet is contacted with the outer wall of the flexible pipe body in an elastic state to prevent the flexible pipe body from being loosened; when the hose body needs to be taken out, the pressing ring is pressed towards the inside of the pipe joint, and the anti-falling elastic sheet is jacked up at the bottom of the pressing ring and separated from the outer wall of the hose body, so that the hose body can be taken out smoothly.

The invention has simple structure, easy realization and low cost; the connection strength between the hoses can be improved, and the leakage hidden danger is reduced; but also can be quickly plugged and pulled out, thereby improving the convenience of hose connection.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

Referring to fig. 1, the invention provides a quick-assembly hose with a lining for solving the hidden leakage problem caused by the deformation of the hose due to stress in the hose connecting pipeline, which is used for connecting the hose to the fluid conveying pipeline, and comprises a pipe joint and a front and a rear two-stage concentric circular cavities arranged in the pipe joint, wherein a sleeve 6 and a hose body 1 fixed outside the sleeve 6 are sequentially arranged in the large-inner-diameter cavity at the front side, a boss for axially limiting the hose body 1 is arranged at the rear end part of the sleeve 6, the sleeve 6 is prevented from entering the hose body 1, the boss is axially limited by the small-inner-diameter cavity at the rear side, the sleeve 6 is prevented from entering the small-inner-diameter cavity at the rear side, a sealing ring 4 is also arranged outside the sleeve 6, when the hose body 1 is inserted into the pipe joint, the outer wall of the hose body 1 is contacted with the sealing ring, as in figure 3 right side ellipse circle part, the front end exit department of coupling is provided with clamping ring 2 for the shutoff, big internal diameter die cavity inner wall seted up type groove, the annular in be provided with the anticreep shell fragment 3 that is certain contained angle (acute angle) with the axial, anticreep shell fragment 3 contacts with the outer wall of flexible pipe body 1 under elastic state, can prevent that flexible pipe body 1 from loosening, like in figure 4 left side circle part.

Furthermore, the pipe joint is externally provided with a thread 5 for connecting a fluid conveying pipeline. The sleeve 6 is made of stainless steel, as shown in fig. 2, the sealing strength of the flexible pipe body 1 can be increased, the outer wall of the flexible pipe body 1 is stably contacted with the sealing ring 4 in the pipe joint, and the hidden trouble of water leakage caused by the forced deformation of the flexible pipe body 1 is solved.

As shown in fig. 3, when the flexible pipe body 1 is inserted into the pipe joint, the outer wall of the flexible pipe body 1 contacts with the sealing ring 4 inside the pipe joint to form a sealing surface, and the sealing surface is a key part of the sealing structure of the pipe joint; the anti-falling elastic sheet 3 is contacted with the outer wall of the flexible pipe body 1 in an elastic state, so that the flexible pipe body 1 can be prevented from being loosened.

As shown in fig. 4, when the flexible pipe body 1 needs to be taken out, the pressing ring 2 is pressed towards the inside of the pipe joint, and the bottom of the pressing ring 2 jacks up the anti-falling elastic sheet 3 to be separated from the outer wall of the flexible pipe body 1, so that the flexible pipe body 1 can be taken out smoothly.

The invention can solve the leakage problem caused by the unstable joint of the outer wall of the flexible pipe body 1 and the sealing ring 4 in the pipe joint due to the stressed deformation of the flexible pipe body 1 in the using process.

The above-described embodiments are merely illustrative of the principles and effects of the present invention, and some embodiments may be applied, and it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the inventive concept of the present invention, and these embodiments are within the scope of the present invention.
