Description

Torsion structure

The present invention is related to a torsion structure, especially a torsion structure provided with the first rod body and the pivotal member. When the rotating torque of the torsion structure reaches a set value, the drive block in the second cavity When the first abutting portion is released, the force of the first abutting portion to hit the second container is relatively small.

According to what I know before, the conventional torque structure is also a patent filed by me. 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:

Please supplement it with the eighth figure, the second pivot portion 22 and the first pivot portion 12 are aligned and the first pivot member 71 penetrates, 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 rotation torque reaches the set value, the driving block 60 can jump out of the first abutting portion 24 and the second abutting portion 51, so that the first abutting portion 24 With the first pivoting member 71 as the axis, it swings to the left or right in the accommodating space 11 to knock the first body 10 to emit a prompt sound, but the first abutment portion 24 and the pivot Pieces 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 The impact force 24 is easy to be greater, and it is easy to strike the first body 10 and cause the first body 10 and the first abutting portion 24 to be damaged.

In view of the above-mentioned shortcomings of the conventional structure, the present inventor has finally produced a product with a torsion structure that can solve the drawbacks of the conventional structure through years of experience in manufacturing, production and design in related industries.

In the conventional torque wrench structure, the first abutting portion The angle of yaw displacement is very small. In the torsion structure of the present invention, the first abutting portion is close to the second pivot portion, that is, the shaft center, and there is a small distance between the two so that the first The angle of the yaw displacement of the abutting part is larger, the yaw angle of the first rod body is larger, and the swing angle of the driving head is also larger.

The present invention relates to a torsion structure, which includes Including: a first system with a first container; a second system with a second container and a first pivot; a first rod system with a second pivot and a first abutment And a third pivot; a pivot member is provided with a fourth pivot and a first pivot slot; a driving head is provided with a driving part, the driving head is provided with a pivot seat, and the pivot seat is pivoted Set in the second accommodating slot, the pivot seat is provided with a fifth pivot, the fifth pivot is pivoted to the second pivot, and the other end of the driving head is provided with a sixth pivot .

The present invention is mostly provided with the first rod body and the pivot When the rotating torque of the torsion structure reaches a set value, the driving block in the second receiving slot jumps out of the first abutting portion, and the first rod system takes the second pivot portion as the axis, The first abutting portion is deflected to the left or right in the second accommodating groove to knock the second body to emit a prompt sound, because the first abutting portion is connected to the second pivot, that is, the axis The first pivoting member is close to each other and has a smaller distance, so that the angle of the first abutment portion's yaw displacement is larger, the first rod body's yaw angle is larger, and the swing angle of the drive head 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 the members of the Jun Council and those 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 drawings and figure numbers.
