Description

Torsion structure

The present invention is related to a torsion structure, especially in a torsion structure, the locking seat is a single element, the locking seat has the advantage of low cost, the second body has a lower production cost, and the torsion structure is integral The production is to reduce production costs.

According to our previous knowledge, the conventional torque structure, such as US Patent No. US6463834B2, is composed of: a torque wrench 10, the torque wrench 10 includes: a first body 20, the first body 20 One end is provided with a quadrangular head-shaped driving part 21; a second body 30, the second body 30 is pivoted to the first body 20, the first body 20 is partially accommodated in the second body At one end of 30, the driving portion 21 is protruding out of the second body 30, and a plurality of positioning portions 33 are provided on the outer peripheral surface of the other end of the second body 30, and the plurality of positioning portions 33 are opposite to the first body 20. Far away, the plurality of positioning portions 33 are arranged in a ring shape with the axis of the second body 30, the positioning portions 33 are in the shape of a concave arc groove, and the second body 30 is in the shape of a hollow round rod; The elastic member 50 is accommodated in the second body 30, the elastic member 50 is elastically pressed between the first body 20 and the second body 30, and the elastic member 50 makes the first body 20 has the effect of torque jumping; A third body 60 is assembled with the second body 30. The third body 60 can adjust the length of the elastic member 50 relative to the second body 30 to adjust the torque value.

But the shortcomings of this conventional torsion structure are:

1. As shown in Figure 2 of the Bulletin, the second body 30 is provided with the plurality of positioning portions 33 on the outer peripheral surface. The main function of the plurality of positioning portions 33 is to provide the third body 60 relative to the second body 30 has a locking function, that is, the third body 60 cannot rotate relative to the second body 30, the positioning portion 33 and the second body 30 are integrally formed, and the processing cost of the plurality of positioning portions 33 is relatively high Therefore, the second body 30 has a higher manufacturing cost. The third body 30 was originally a tube-shaped body and then used a cutting method to set the plural positioning portions 33. The cutting method is generally a milling cutter with a straight line The path mills out each positioning portion 33. If there are 10 positioning portions 33, it will be milled out 10 times, and each time the second body 30 is rotated by 36 degrees, if the positioning portions 33 are 20 At that time, it must be milled 20 times, and each time the second body 30 is rotated by 18 degrees, the cutting method system will have multiple steps to complete the punching.

2. The plurality of positioning parts 33 have 10 or 20 according to the locking mode, so there are at least two kinds of the second body 30, one of the second body 30 has 10 plural positioning parts 33, and the other second body 30 has 10 plural positioning parts 33. The main body 30 has 20 plural positioning portions 33, so that the second main body 30 has twice the inventory, and the second main body 30 has a longer length, the second main body 30 needs to have a larger inventory Space storage.

In view of the above-mentioned shortcomings of the conventional structure, the inventors have used years of experience in manufacturing, production and design in related industries to finally have a product with a torsion structure that can solve the drawbacks of the conventional structure.

The problem to be solved by the invention: In the conventional torsion structure, the processing cost of the plurality of positioning parts is relatively high, so that the second body has a higher manufacturing cost. In the torsion structure of the present invention, the locking seat has the advantage of low processing cost, the second body has a lower production cost, and the processing cost of the locking seat is also lower, and the overall production of the torsion structure is reduced Cost of production.

Technical means to solve the problem: a torsion structure, which includes: a first system with a first accommodating slot; a second system with the first body pivoted, and the second system partially accommodates In the first accommodating groove, one end of the second body is provided with a driving part; an elastic element is accommodated in the second body, and the elastic element directly or indirectly elastically abuts against the second body, the The elastic element makes the second body have a torsion release effect; a locking seat assembly is assembled with the second body, the locking seat assembly includes a locking seat; the locking seat is assembled on the second body At the end, the locking seat cannot be displaced or rotated relative to the second body, the locking seat is provided with a first pivot, the first pivot penetrates the locking seat, and the outer of the locking seat is provided with a plurality of positioning groove.

Compared with the effect of the prior art: the locking seat has the advantage of low processing cost, the second body does not need to be provided with the plurality of positioning grooves, the second body has a lower production cost, and the processing cost of the locking seat It is also lower, and the overall production of the torsion structure reduces the production cost.

In order to enable 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 will be described in conjunction with the drawings and figure numbers. However, the following are only In order to explain the embodiments of the present invention, it is not an attempt to restrict the present invention in any form.
