Description

Torsion structure

The present invention is related to a torsion structure, in particular, a torsion structure in which the processing process of the hollow tube structure of the second body is relatively simple. The second body only needs to process the first screw-on part, and the processing cost of the second body is relatively cheap. The third body also needs to process the fourth screw-on part and be screwed together with the first screw-on part. The fourth screw-on part and the first screw-on part are assembled quickly.

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 shortcomings of this conventional torsion structure are:

Please refer to Figure 2 of the US Gazette. The tube 11 and the active end 12 are an integral structure. The tube 11 has a through hole for accommodating the clutch 40 and the elastic element 50. The through hole in the tube 11 can only be drilled with a gun drill to a hole of a considerable length. The machining process of the through hole in the tube 11 is relatively difficult, and the machining 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 the relevant industry, finally came up with a torsion structure product that can solve the conventional shortcomings.

Problems to be solved by the invention: In conventional torque structures, the tube and the action end are an integral structure. The through hole in the tube can only be drilled with a gun drill. The processing procedure of the through hole in the tube is relatively difficult, and the processing cost of gun drill drilling is relatively high. In the torque structure of the present invention, the processing process of the hollow tube structure of the second body is relatively simple. The second body only needs to process the first screw-on part. The processing cost of the second body is relatively cheap and saves the cost of the second body. The third body also needs to process the fourth screw-on part and be screwed with the first screw-on part. The screw-on structure of the fourth screw-on part and the first screw-on part is fast when assembled.

Technical means to solve the problem: A torsion structure, which includes: a first body is provided with a first accommodating groove; a second body assembly includes a second body, a screw seat, a screw, a screw-engaging member and an elastic element; the second body is provided with a first screw-engaging portion; a second screw-engaging portion is provided inside the screw seat; the screw is provided with a third screw-engaging portion; the screw-engaging member and the third screw-engaging portion are screwed together, and the screw-engaging member abuts against the screw seat; a third body assembly includes: a third body and a rotating member; the third body is provided with a fourth screw-engaging portion; the rotating member is provided with a first outer peripheral surface, a first inner peripheral surface, a plurality of first flanges and a plurality of first recesses on the outside; a moving assembly includes a moving member, a first bead and a second bead; the moving member is provided with a first abutting portion and a second abutting portion.

Compared with the effect of the prior art: the third body assembly is a structure assembled with the second body assembly, and the processing process of the hollow tube structure of the second body is relatively simple. The second body only needs to process the first screwing part, and the processing cost of the second body is relatively cheap and saves component costs. The third body also needs to process the fourth screwing part and be screwed with the first screwing part. The assembly of the screwing structure of the fourth screwing part and the first screwing part is quite fast. The third bead is against the elastic element, and the elastic element is in the shape of a ring body. The third bead is easier to align with the elastic element. The axis of the moving assembly is easier to align with the axis of the elastic element, thereby reducing the axis deviation between the two and causing the error of the torque value. After the second body assembly and the third body assembly are assembled, the screw is rotated to adjust the torque value. When the required torque is adjusted, the screw-in component is screwed on the third screw-in portion and abuts against the screw-in seat, so that the screw is fixed in position and the torque cannot be adjusted. The second body assembly can be inserted into the first body, and the torque structure is a fixed torque structure.

The advantages of the torsion structure of the present invention are:

1. The third body assembly 30 is assembled with the second body assembly 20. The processing process of the hollow tube structure of the second body 21 is relatively simple. The second body 21 only needs to process the first screw-fitting portion 211 and the first through hole 212. The processing cost of the second body 21 is relatively cheap and saves component costs.

2. The third body 31 also needs to process the fourth screw-on part 311 and screw it with the first screw-on part 211. The screw-on structure of the fourth screw-on part 311 and the first screw-on part 211 is assembled very quickly.

3. The third bead 43 is against the elastic element 28. The elastic element 28 is in the shape of a ring. The third bead 43 is easier to align with the elastic element 28. The axis of the moving assembly 40 is easier to align with the axis of the elastic element 28, thereby reducing the axis deviation between the two and causing the error of the torque value.

4. After the second body assembly 20 and the third body assembly 30 are assembled, the screw 23 is rotated to adjust the torque value. When the required torque is adjusted, the screw member 25 is screwed on the third screw portion 231. The screw member 25 is against the screw seat 22, so that the screw 23 is fixed in position and the torque cannot be adjusted. The second body assembly 20 can be inserted into the first body 10. The torque structure is a fixed torque structure.

5. After adjusting the fixed torque, the first body 10 is then mounted on the second body 20. When the first body 10 is mounted, it is aligned with the third body assembly 30, and the torque structure will not have any defects due to misalignment in appearance.

6. When the torque exceeds the preset value, the rotating member 33 will rotate, and the first flange 333 will push the moving group 40, and the moving group 40 will compress the elastic element 28, so that the third body group 30 has a tripping effect.

7. The second body assembly 20 and the third body assembly 30 are screwed together, and the moving assembly is against the rotating member 33 and the elastic element 28. The moving assembly 40 can have a displacement effect. The second body assembly 20 has a more cost-saving effect and can be shared with other different third body assemblies 30 to have the best of both worlds.

8. The main principle of the present invention is that the moving assembly 40 must be displaced to enable the third body assembly 30 to have a torque jump-off effect, the moving member 41 is accommodated between the rotating member 33 and the elastic element 28 to have a displacement effect, and the second body assembly 20 and the third body assembly 30 are screw-mounted structures. This assembly method can share the second body 20 and can assemble different third body assemblies 30 to have dual effects.

Therefore, the torsion structure of this invention has industrial applicability, novelty and advancement, and can truly meet the application requirements for invention patents, so we have filed an application in accordance with the law.
