Description

Torsion structure

The present invention is related to a torsion structure, especially a torsion structure in which the grip set and the first body and the second body are not displaced relative to each other, that is, regardless of the torque value of the torsion structure is large or small, The overall length of the torsion structure is the same.

According to my previous knowledge, the conventional torque structure is also the previous patent application that I applied for. Taiwan patent application number: 106135035, certificate number: I633978, patent name: locking torque wrench, the structure of the patent case is: A locking type torque wrench, comprising: a main rod body 10 having a driving end 11 and an installation end 12, the driving end 11 is provided with a driving portion 13 for receiving a work piece; The adjusting tube 20 has a first end 21 and a second end 22, the first end 21 is sleeved on the mounting end 12, and the adjusting tube 20 is provided with a through groove 24 near the outer periphery of the second end 22 ; A torque adjustment assembly 30, which is provided between the main rod body 10 and the adjustment tube 20; a positioning member 40, which is connected to the torque adjustment assembly 30 and one end away from the installation end 12, the positioning member A positioning groove 41 is recessed on the outer periphery of 40, and the positioning groove 41 corresponds to the through groove 24; a catch 50 is movably arranged in the through groove 24; and a locking ring 60 is sleeved on the adjustment tube 20 The second end 22 is rotated relative to the adjusting tube 20 between a locked position and a relaxed position. The axial inner peripheral edge of the locking ring 60 is recessed with an action groove 61 which corresponds to the catch 50. The working groove 61 has a first recess 611 and a second recess 612, the first recess 611 and the second recess 612 are connected to each other, wherein the inner periphery of the locking ring 60 is recessed along the axial direction with a first recess. Three recesses 62, the third recess The portion 62 is connected to the first concave portion 611 and staggered; in the locked position, the catch 50 is clamped between the positioning groove 41 and the first concave portion 611 of the acting groove 61; in the relaxed position, the catch The sub 50 is movably displaced between the positioning groove 41 and the second recess 612 of the acting groove 61.

However, the shortcomings of this conventional locking torque wrench are:

1. As shown in Figure 1 of the Bulletin, the locking ring 60 is sleeved on the second end 22 of the adjusting tube 20. The user uses one hand to cut and turn the locking ring 60 to make the locking ring 60 rotate relative to the adjusting tube 20 to a locked position and a relaxed position to control the adjusting tube 20 to be non-rotating or rotating relative to the main rod body 10, but usually the driving part 13 is used to receive the work piece to be rotated When moving, the user holds the adjusting tube 20 with his dominant hand and rotates the torque wrench structure. Since the locking ring 60 is located at the end of the torque wrench 100, the user is accustomed to holding When the end of the holding part is about to cut and turn the locking ring 60, it can be operated with the other hand over the dominant hand holding the adjustment tube 20. For example, when the right hand holds the adjustment tube 20, the left hand will pass over the right hand. When the locking ring 60 is switched, the user's hands are crossed and it is not convenient to turn the locking ring 60 easily, or it is easy to confuse the direction of turning, which is not convenient.

2. The locking ring 60 can be rotated relative to the adjusting tube 20 to a locked position and a relaxed position to control the adjusting tube 20 to be non-rotating or rotating relative to the main rod body 10. When the ring 60 rotates to the relaxed position, so that when the adjusting tube 20 rotates relative to the main rod body 10, the adjusting tube 20 rotates and displaces relative to the main rod body 10 and at the same time drives the pushing member 32 to displace and press against the elastic member 31. Adjust the torque value by adjusting the degree of compression of the elastic member 31. When the elastic member 31 is in the most compressed state, the torque value of the torque wrench is the maximum, but the adjustment tube 20 and the main rod body 10 are The relative length is the shortest shape, that is, the overall length of the torque wrench is the shortest shape, and its length and torque value do not meet the requirements.

3. As shown in Figures 2 and 8 of the bulletin, when the locking ring 60 is rotated to the relaxed position, the pawl 50 corresponds to the gap between the positioning groove 41 and the second recess 612, and the pawl 50 That is, without being restricted by the first recess 611, the adjusting tube 20 can rotate and displace relative to the main rod body 10, but when the adjusting tube 20 rotates relative to the main rod body 10 to adjust the torque value, the adjusting tube 20 When rotating, there is no warning sound that can be issued when rotating, so as to understand the torque value status of the torque wrench. The operation is not convenient.

In view of the above-mentioned shortcomings of the conventional structure, the present inventor has finally produced a product with a torsion structure that can solve the drawbacks of the conventional structure through years of experience in manufacturing, production and design in related industries.

The problem to be solved by the invention: In the conventional locking type torque wrench structure, the overall length of the torque wrench is the shortest shape but the torque system is the maximum shape, and its length and torque value do not meet the requirements. In the torque structure of the present invention, the There is no relative displacement between the grip set and the first body and the second body, that is, the overall length of the torsion structure is the same regardless of whether the torsion value of the torsion structure is large or small.

Technical means to solve the problem: The present invention relates to a torsion structure, which includes: a first system with a first accommodating groove and a first through groove; a second system with a guide groove; and an elastic element The second body has the function of torsion release; a control group can be moved to a locked position and a non-locked position; a first fixed group, the first fixed group is fixed in the first housing In the groove; an adjustment group can be screwed and displaced in the first fixed group, so that the adjustment group can be screwed and displaced in the first containing groove and the second body to adjust the length of the elastic element; The positioning ring is nested with the adjusting member, and the positioning ring rotates in situ with the rotation of the adjusting member; a handle group rotating system drives the adjusting group to rotate, so that the adjusting group rotates at the first fixed group And displacement.

Compared with the effect of the prior art: the hand grips the grip set and rotates the torsion structure. After the control group is turned on the first body to the unlocked position, the hand directly rotates the grip set and directly To adjust the torque value of the torque structure, the torque value can be adjusted without shifting the hand, so the operation is more convenient and smooth. There is no relative displacement between the grip set and the first body and the second body, that is, the overall length of the torsion structure is the same regardless of whether the torque value of the torsion structure is large or small.

In order to enable the members of the Jun Council and those familiar with the art to fully understand the effects of the present invention, the structure and composition of the present invention are described in conjunction with the drawings and figure numbers. However, the following are only used to explain the implementation of the present invention For example, it is not an attempt to restrict the present invention in any form, so any modification made under the spirit of the present invention should still fall within the protection scope of the present invention.
