Description

Torque wrench structure

The present invention relates to a torque wrench structure, in particular, a torque wrench structure is provided with the first elastic body and is fixed in the first body, the first elastic body has structural support force and saves component cost. The first elastic system achieves the best results in terms of structural support and overall cost.

As we have previously known, the conventional torque wrench structure is also the patent application filed by us, such as Taiwan Patent Application No. 106202230, Certificate No.: M541927, Patent Name: Torque Wrench Structure, Structure: A Torque Wrench Structure The outer tube 10 is provided with an accommodating space 13 in the axial direction. A driving member 20 has a driving head 21 at one end and a connecting end 22 at the other end. The driving member 20 is pivotally mounted on the outer tube. At the one end of the 10, the connecting end 22 extends into the accommodating space 13; a holding member 30 is slidably disposed in the accommodating space 13 and connected to the connecting end 22; a kit 40 is disposed on the outer tube 10 and the holding member 30; and a torque adjusting device 50 disposed at the outer tube 10 and different from one end of the driving member 20, the torque adjusting device 50 is operated to adjust the torque value.

This new patent case also has an application for invention patent, application number 106105035, patent name: torque wrench structure, the invention patent should be able to grant patent after applying for narrowing the patent scope.

However, the absence of this patent is based on:

1. Referring to FIG. 1, the outer tube 10 of the torque wrench structure generally has a longer length for the driving member 20, the holding member 30, the torque adjusting device 50 or other components to be compatible. Generally, the outer tube 10 has no heat treatment step, and the heat treatment processing system makes the cost of the outer tube 10 relatively high.

2. According to the above point, 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 circular tube structure, and the outer tube 10 is The structural strength is insufficient.

3. A kit 40 is provided. The kit 40 is disposed between the outer tube 10 and the top member 30. The function of the sleeve 40 can support the inner circumferential surface of the outer tube 10 to increase the structural strength of the outer tube 10. The kit 40 is a spring structure, and the kit 40 has a relatively small component cost, but the kit 40 is limited by the fixing member 33, and the sleeve 40 is slid with the holding member 30 at a small distance. That is, the sleeve 40 will slide in the outer tube 10, so that the supporting force of the sleeve 40 supporting the outer tube 10 is slightly lowered.

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

However, the absence of this patent is based on:

As shown in FIG. 1 of the publication, the body 10 is fixed on the inner circumferential surface of the outer tube 2, so that the body 10 has better support for the outer tube 2 than the kit 40 of the certificate No. M541927. The outer edge 11 of the body 10 and the inner edge 12 are in a discontinuous contact relationship. Therefore, the body 10 is originally formed to have a flat plate shape of the outer edge 11 and the inner edge 12. 10 is then completed by the bending method and is as shown in Fig. 1. However, when it is completed by the bending method, it is not a regular cylinder as shown in Fig. 1. The body 10 is composed of a complex angle. The polygonal cylindrical shape and the cost of forming the body 10 by the bending and dismantling method are also relatively high, which is also inconsistent with the production efficiency, and a relative lack occurs.

In the patent case filed by the two of us, the kit 40 of the M541927 is lower in cost, but it is less supportive. The body 10 of the M556638 has a large cost, but has structural support. Force, between the two patents, the kit 40 or the body 10 is not the best.

In view of the lack of the above-mentioned conventional structure, the creator has been engaged in the manufacturing, production and design experience of related industries for many years, and finally has a product that can solve the drawbacks of the torque wrench structure.

In the patent case filed by the two of us, The kit of M541927 is lower in cost, but it is less supportive. The system of M556638 has a large cost, but it has structural support. Between two patents, the kit or The first elastic body of the present invention has structural support and saves component cost, and the first elastic system achieves the best effect on structural support force and overall cost.
