Description

Torque wrench structure

The invention relates to a torque wrench structure, in particular to a torque wrench structure provided with the first elastic body and fixedly disposed in the first body. The first elastic body has structural support force and saves component costs. The first elastic system achieves the best results in structural support and overall cost.

According to my previous knowledge, the conventional torque wrench structure is also a patent filed by me, such as Taiwan Patent Application No. 106202230, certificate number: M541927, patent name: Torque wrench structure, the structure is: a torque wrench structure It includes: an outer tube 10 having an accommodating space 13 in the axial direction; a driving member 20 having a driving head 21 at one end and a connecting end 22 at the other end; the driving member 20 is pivoted on the outer tube One end of 10, the connecting end 22 extends into the accommodating space 13; a top holder 30, which is slidably disposed in the accommodating space 13, and is connected to the connecting end 22; 10 and the holding member 30; and a torque adjusting device 50, which is disposed on the outer tube 10 and different from one end of the driving member 20, and operates the torque adjusting device 50 to adjust the torque value.

This new patent case also has an application for an invention patent, application number 106105035, patent name: Torque wrench structure. The invention patent should be granted after the scope of the patent is narrowed.

But the lack of this patent case is:

1. Please supplement as shown in Figure 1. The outer tube 10 of the torque wrench structure usually has a longer length for the driving member 20, the holding member 30, the torque adjusting device 50 or other components to be compatible. In general, the outer tube 10 does not undergo a heat treatment step, and the cost of the outer tube 10 is quite high due to the heat treatment process.

2. According to the point above, the outer tube 10 has a considerable length, and the outer tube 10 is not subjected to a heat treatment step, and the outer tube 10 is a hollow round pipe structure. The structural strength is inadequate.

3. A kit 40 is provided between the outer tube 10 and the holding member 30. The function of the kit 40 is to support the inner peripheral surface of the outer tube 10 to increase the structural strength of the outer tube 10. The kit 40 is a spring structure, the kit 40 has a relatively small component cost, but the kit 40 is limited to the fixing member 33, and the kit 40 will slide a small distance with the holding member 30 That is, the kit 40 slides in the outer tube 10, which makes the supporting force of the kit 40 supporting the outer tube 10 slightly lower.

Another Taiwan patent case, this is also a patent case filed by me, application number: 106217438, certificate number: M556638, patent name: bushing structure of torque wrench, the patent case structure is: a bushing structure of torque wrench The torque wrench 1 has an outer tube 2, a driving member 3 and a holding member 4, wherein the outer tube 2 is provided with an accommodation space 2c in the axial direction; one end of the driving member 3 has a driving head 3a, and the other end There is a connecting end 3b, the driving member 3 is pivoted on one end of the outer tube 2, the connecting end 3b extends into the accommodation space 2c; the holding member 4 is slidably disposed in the accommodation space 2c, and is connected to the accommodation space 2c The connecting end 3b; the bushing structure of the torque wrench includes: a body 10, which is substantially cylindrical, the body 10 is disposed in the accommodation space 2c and is sleeved on the holding member 4 along the axial direction of the outer tube 2. The body 10 has an outer edge 11 and an inner edge 12. The outer edge 11 and the inner wall surface of the outer tube 2 are formed. In a discontinuous contact relationship, the inner edge 12 and the holding member 4 are in a discontinuous contact relationship.

However, the lack of this patent case is as follows: as shown in FIG. 1 of the bulletin, the body 10 is fixed on the inner peripheral surface of the outer tube 2. Therefore, the body 10 has the advantages of the kit 40 of certificate number M541927. The effect of supporting the outer tube 2 is better, but the outer edge 11 and the inner edge 12 of the body 10 are in a non-continuous contact relationship, so the body 10 originally has the outer edge 11 and the inner edge 12 It is a flat plate-like body. The body 10 is formed into a right-cylindrical shape as shown in FIG. 1 after being completed by the bending method. However, when the bending method is completed, it is not a right-cylindrical shape as shown in FIG. The body 10 is a polygonal cylinder composed of a plurality of angles, and the cost of making the body 10 by the bending and tearing method is also quite high, that is, it does not conform to the production efficiency, resulting in a relative lack.

In the two patents we applied for, the kit 40 of the M541927 is lower in cost but less supportive. The body 10 of the M556638 has a larger cost, but it has structural support. Force, between the two pre-patent cases, the kit 40 or the body 10 cannot be the best of both worlds.

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

In the two patents that I applied for, the package of the M541927 is lower in cost but less supportive. The M556638 has a larger cost of the system, but it has structural support. Between two pre-patent cases, the kit or There is no best of both worlds between the bodies. The first elastic body of the present invention has structural support and saves component costs. The first elastic system achieves the best effect in terms of structural support and overall cost.

A torque wrench structure includes: a first system is provided with an accommodation space, a first pivot portion, a first end, and a second end; a second system is accommodated in the accommodation space, and the second One end of the body is provided with a driving head, one end of the second body is provided with a second pivot portion to be pivoted with the first pivot portion, and the other end of the second body is recessed with a first abutting portion; a first The elastic system is fixed at the inner peripheral surface of the second end, and the first elastic system is assembled at the inner peripheral surface of the second end with an external force.
