Description

Torsion structure

The present invention is related to a torsion structure, especially a torsion structure

According to what I have previously known, the conventional torque structure is also a patent filed by us. For example, the Taiwan patent application number: 107132640, certificate number: I661906, patent name: torque wrench structure, the structure is: a torque wrench structure, It includes: a first body 10; a second body 20; a first elastic body 40; an abutting member 50; a driving block 60; a second elastic body 70; and a first pivoting member 71.

But the shortcomings of this conventional torsion structure are:

As shown in the eighth figure, the second pivot portion 22 and the first pivot portion 12 are aligned and the first pivot member 71 is inserted through, so that the first body 10 and the second body 20 The first abutment portion 24 is separated from the second pivot portion 22, and there is a distance between the first abutment portion 24 and the second pivot portion 22, and the torque wrench structure is clockwise. When the rotating torque reaches the set value, the driving block 60 can jump out of the first abutting portion 24 and the second abutting portion 51 to make the first abutting portion 24 With the first pivoting member 71 as the axis, the first body 10 is swung to the left or right in the accommodating space 11 to make a prompt sound, but the first abutting portion 24 and the pivoting member The axis of 71 has a long distance, so that the angle of the yaw displacement of the first abutting portion 24 is small, and the first abutting portion 24 has a longer force distance, the first abutting portion 24. The impact strength is easy to be greater, and it is easy to hit the first body 10 and cause the first body 10 and the first abutting portion 24 to be Depletion.

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 torque wrench structure, the angle of the first abutting part's yaw displacement is very small. In the torsion structure of the present invention, the first abutting part is connected to the second pivot part, that is, the shaft The center is close to each other, and the distance between the two is relatively small, so that the angle of the first abutting part's yaw displacement is relatively large, the yaw angle of the first rod body is relatively large, and the swing angle of the driving head is also Bigger

Technical means to solve the problem: the present invention relates to a torsion structure, which includes: a first system with a first container; a second system with a second container and a first pivot; A rod system is provided with a second pivot part, a first abutment part and a third pivot part; a pivot member is provided with a fourth pivot part and a first pivot groove; a driving head is provided with a driving part, The driving head is provided with a pivot seat, the pivot seat is pivoted in the second receiving slot, and the pivot seat is provided with a fifth pivot part, the fifth pivot part is connected to the second pivot part A sixth pivot is arranged at the other end of the driving head.

Compared with the effect of the prior art, the present invention is provided with the first rod body and the pivotal member. When the rotating torque of the torsion structure reaches a set value, the driving block in the second cavity is released from the first rod. At an abutting part, the first rod system takes the second pivot part as the axis, so that the first abutting part is deflected to the left or right in the second accommodating groove to knock the second body to emit Beep, due to the first The abutment portion is close to the second pivot portion, that is, the first pivotal member at the shaft center, and has a small distance, so that the angle of the first abutment portion's yaw displacement is larger, and the first rod The body swing angle is larger, and the swing angle of the drive head is also larger. There is a small distance between the first abutting portion and the second pivot portion, that is, the first abutting portion has a small moment, and the force of the first abutting portion hitting the second cavity is small, namely It is less likely to hit the second body to cause the loss of the second body and the first abutting portion.

In order to enable members of the Jun Council and those who are familiar with the art to fully understand the effects of the present invention, the structure and composition of the present invention are described in conjunction with the figures and figure numbers. However, the following descriptions are only used to explain the implementation of the present invention. For example, it is not an attempt to restrict the present invention in any form.
