Description

Torque wrench structure

The invention relates to a structure of a torque wrench, especially a structure of a torque wrench, which is provided with a first washer, which can provide a buffering effect, so that the first head of the adjusting member is not directly connected with the fixing seat Collision caused collision.

According to my previous knowledge, the structure of the conventional torque wrench is supplemented by the sixteenth and seventeenth figures. The sixteenth figure is a three-dimensional exploded view of the structure of the conventional torque wrench, and the seventeenth figure is the structure of the conventional torque wrench Front view of some components, a torque wrench 90, the torque wrench 90 includes a second body 91, a first seat 92, two coupling members 93, a screw 94 and a third body 96; the second body 91 One end is provided with a second accommodating groove 912, the second accommodating groove 912 is a circular groove, the second body 91 is provided with two first coupling portions 913, and the two first coupling portions 913 are disposed near the first Near the opening of the two receiving slots 912, the first combining portion 913 is in communication with the second receiving slot 912; the first seat 92 is received in the second receiving slot 912 of the second body 91, The first seat body 92 is in the shape of a ring. A first screw portion 921 is provided in the first seat body 92. The first screw portion 921 penetrates the first seat body 92. The first screw The coupling portion 921 is internally threaded. The first base 92 is provided with two second coupling portions 922. The second coupling portion 922 is opposite to the first coupling portion 913. The two second coupling portions 922 are In a symmetrical shape, the second joint portion 922 is an internal screw Striated; the coupling member 93 is coupled to the first coupling portion 913 and the second coupling portion 922, so that the first seat 92 is fixed in the second receiving groove 912, the coupling member 93 is It is externally threaded; the screw 94 is partially exposed outside the second body 91, the screw 94 is provided with a second screwing portion 941, the second screwing portion 941 and the first screwing portion 921 The second screwing portion 941 can be spirally displaced at the first screwing portion 941, a second head 942 is provided at one end of the screw 94; the third body 96 is connected to the second body 91 The third body 96 can rotate and displace relative to the second body 91, and the third body 96 is nested with the first screw 94. When the third body 96 is rotated and displaced, the screw 94 is driven The helical displacement at the first screwing portion 921 adjusts the compression degree of the spring in the second body 91 to adjust the torque value of the torque wrench structure.

But the lack of the structure of this conventional torque wrench lies in:

1. When the user rotates the third body 96 to rotate the third body 96 on the second body 91, the third body 96 simultaneously drives the second screw portion 941 of the screw 94 on the The first screwed portion 921 is spirally displaced. When the second screwed portion 941 is rotated to its end, the second head 942 will abut the end of the first seat 92, so The two may collide and cause wear.

2. If the screw 94 has been rotated until the second head 942 is in abutment with the first seat body 92, that is, when the screw 94 cannot rotate anymore, the user has not noticed that the action of adjusting the torque has arrived At the end, when the operator continues to rotate the third body 96, or some people have turned to the end, The third body 96 will continue to rotate. If the force is too large, the third body 96 will apply force to the screw 94, and the screw 94 will then apply force to the first seat body 92. The first After the seat body 92 is stressed, the first seat body 92 is forced on the two coupling members 93, which is generally limited by the space. The diameter of the coupling member 93 is not large, and the coupling member 93 is possible. If it cannot withstand the force of its rotation and breaks, the first base 92 may fall out of the second receiving slot 912, causing damage to the structure of the torque wrench.

In view of the lack of the above-mentioned conventional structure, the inventor, after years of experience in manufacturing, production and design in related industries, finally came up with a product that can solve the disadvantages of conventional torque wrench structures.

The problem to be solved by the invention: In the structure of the conventional torque wrench, when the second screw part is rotated to its end, the second head will abut against the end of the first seat body, so two A collision may occur between them, causing damage. The torque wrench structure of the present invention is provided with a first washer to provide a buffering effect, so that the first head of the adjusting member does not directly collide with the fixing seat to cause a collision damage.

Technical means for solving the problem: The present invention relates to a torque wrench structure, which includes: a first system with a first receiving groove; a fixing seat fixed in the first receiving groove and provided with a first thread Part; an adjusting member is provided with a second threaded portion, a first head, a first abutting surface, a second abutting surface and a ring groove; at least a first washer is accommodated in the ring groove; The second threaded portion of the adjusting member rotates and displaces in the first threaded portion, so that when the first head is close to the fixing seat, the first washer can provide a cushioning effect, so that the first head is Not straight When it collides with the fixing seat, the first washer is pressed against the fixing seat and the first abutment surface.

According to the effect of the prior art: at least one first washer is provided, the first washer is accommodated in the ring groove, and when the second threaded portion of the adjusting member is rotated and displaced in the first threaded portion of the fixing seat to When the first head is close to the fixing seat, the first gasket can provide a cushioning effect, so that the first head does not directly collide with the fixing seat and cause damage. When the adjustment torque is at the end, that is, when the first head is close to the fixing seat, the first washer can provide a buffering effect, although the first washer can be avoided by rotating the adjustment member, the first washer can avoid the first head The rotating force of the part directly exerts a force on the fixing seat to avoid the force of the fixing member from breaking, and the first washer can prevent the first abutment surface of the first head from directly colliding with the fixing seat . The first washer is a soft material with elasticity, and the cross section of the first washer can be round, square or X-shaped.

In order to make the members of the Jun Bureau and those skilled in the art fully understand the effect of the present invention, the structure and composition of the present invention are described below in conjunction with the drawings and figure numbers, but 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, but any modification or modification made within the spirit of the present invention should still fall within the protection scope of the present invention.
