Description

Torsion structure

The present invention is related to a torsion structure, in particular, a torsion structure in which a moving part must be displaced to enable the third body to have a torsion jump effect. The moving part is provided with a through slot for the second fixed part to pass through. The moving part can be displaced, and the second body can be used to assemble the third body.

As we know before, the commonly used torque structure is also the patent case assigned by us, US Patent No.: US9089957B2, Taiwan Patent Application No.: 102221440, Certificate No.: M473899, Patent Name: Torque Wrench with Constant Torque, the structure of the patent case is: a torque wrench with constant torque, which includes: a wrench body 10; a receiver 20; an abutment column 30; a clutch 40; a handle 50 and an elastic element 60.

However, the defect of this conventional torque structure is that: please refer to Figure 2 of the US Gazette, the tube 11 and the action end 12 are an integral structure, and the tube 11 is a through hole for accommodating the clutch 40 and the elastic element 50. The through hole in the tube 11 can only be processed by using a gun drill to drill a hole of a considerable length. The processing procedure of the through hole in the tube 11 is relatively difficult, and the processing cost of drilling with a gun drill is relatively high.

In view of the above shortcomings of the conventional structure, the inventor, with many years of experience in manufacturing, production and design in related industries, finally came up with a torsion structure product that can solve the conventional shortcomings.

In conventional torsion structures, the tube and the action end are an integrated structure. The through hole in the tube can only be drilled with a gun drill. The machining process of the through hole in the tube is relatively difficult, and the machining cost of gun drill is relatively high. In the torsion structure of the present invention, the third body and the second body are a combined structure. The machining process of the second body is relatively simple, and the machining cost of the second body is relatively cheap, thus saving costs.

The present invention relates to a torsion structure, which includes: a first body having a first receiving groove; a second body having two first through holes; an elastic element received in the second body; a third body having a sleeve and an action end, the sleeve having two third through holes at the proximal end, the action end having a first receiving groove, and the sleeve having a second receiving groove; a rotating member having a first outer peripheral surface and a first inner peripheral surface, the first outer peripheral surface having a plurality of first flanges and a plurality of first recesses; a top abutting member received in the second receiving groove, the top abutting member abutting against the first flange or the first recess; a moving member having a through groove; a second fixing member passing through the plurality of first through holes, the plurality of third through holes and the through groove.

The third body and the second body are assembled together. The hollow tube structure of the second body is simpler to process. The processing cost of the second body is relatively cheap and saves costs. The main principle of the invention is that the moving part must be displaced to enable the third body to have a torsion jump effect. The moving part is provided with a through groove for the second fixed part to pass through. In this way, the moving part can be displaced, and the second body originally assembled with the fourth body can be used to assemble the third body, so that the second body can be shared and the cost of components can be saved.

In order to enable the members of the Jun Bureau and those familiar with this technology to fully understand the effects of the present invention, the structure and composition of the present invention are explained below with diagrams and figure numbers. However, the following is only used to explain the implementation examples of the present invention and is not intended to limit the present invention in any form.
