Description

Torsion structure

The present invention is related to a torsion structure, in particular, in a torsion structure, the first body, the second screw portion, the third screw portion, and the third body actuate the second elastic member to make the first The rotation and displacement of a main body and the action of actuating the second elastic element have the effect of being proportional to the length and the torque value.

According to what I have previously known, the torque wrench structure that I have used is also a patent that I have assigned. For example, the US patent number: US8863624B2, the Taiwan patent application number: 103215530, the certificate number: M492808, the patent name: with locking device The structure of the patent is: a torque wrench with a locking device, which includes: a hollow main rod body 10; a tool member 20; a torque adjusting elastic member 40; a clutch assembly 50; and a The locking device 60 is arranged on the outer periphery of the second end 12 of the main rod body 10, and produces relative axial movement along the main rod body 10 between a locked position and a non-locked position, wherein , The locking device 60 includes a metal locking ring 61, a compression spring 62, a metal C-shaped buckle 63, and at least one metal positioning bead 65.

But the shortcomings of this conventional torsion structure are:

1. As shown in Figure 4, the adjusting screw 31 is assembled in the adjusting handle 30. When the adjusting handle 30 rotates and shifts relative to the main rod body 10, the adjusting handle 30 The adjusting screw 31 is driven to rotate and shift synchronously. The adjusting screw 31 is helically displaced in the second end 12, and the adjusting screw The member 31 actuates the elastic member 40 synchronously, that is, the adjusting handle 30, the adjusting screw member 31 and the elastic member 40 are all actuated as a single unit.

2. When the adjusting screw member 31 is helically displaced in the direction of the first end 11, the abutting member 41 is pressed against the torsion adjusting elastic member 40, so that the torsion adjusting elastic member 40 becomes more compressed to adjust and increase the torque At the torque value of the wrench, the adjusting handle 30 also shifts toward the first end 11, the overall length of the torque wrench is reduced, that is, when the torque adjusting elastic member 40 is in the most compressed shape, the torque wrench The torque value is the maximum shape, but the overall length of the torque wrench is the shortest shape. The torque value is inversely proportional to the total length of the torque wrench, and the length is inversely proportional to the torque value, which does not meet the requirements.

3. Please supplement as shown in Figures 6 to 8 of the US Gazette. When you want to adjust the torque value, move the locking ring 61 to the direction of the adjustment handle 30 to make the locking device 60 slide To the unlocked position, the compression spring 62 is compressed due to the displacement of the locking ring 61, so that the C-shaped buckle 63 is engaged with the ring groove 614 to position the locking ring 61 in the unlocked position. The positioning bead 65 is not pushed by the pushing surface 612 and corresponds to the inclined surface 616, so that the positioning bead 65 can move between the accommodating groove 611 and the positioning groove 13, and the adjusting handle 30 can be opposite The main rod body 10 rotates, but when the adjusting handle 30 rotates relative to the main rod body 10 to adjust the torque value, the adjusting handle 30 is rotated without any prompt sound that can be emitted when rotating. For understanding the current torque status of the torque wrench, it is not convenient to operate.

4. The positioning groove 13 is hidden in the adjusting handle 30. When the adjusting handle 30 is rotated, the positioning bead 65 may not be aligned with one of the positioning grooves 13, and the displacement of the locking ring 61 cannot make the The positioning bead 65 is accommodated in the positioning groove 13, and the locking ring 61 cannot be returned to the locked position, which is inconvenient for operation.

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 structure, the length of the torque wrench is inversely proportional to the torque value. In the torsion structure of the present invention, the first body, the second screw portion, the third screw portion, and the third body actuate the length of the second elastic member to rotate and shift the first body, and The actuation of the second elastic member has the function of having a length proportional to the torque value.

A torsion structure includes: a first body part is provided with an accommodating groove; a second system is provided with a driving part, a first accommodating hole, and a second accommodating hole; The seat is provided with a first screw part; a first adjustment assembly includes a first adjustment part; the first adjustment part is provided with a second screw part and a first container; a second adjustment assembly Comprising a second adjusting member; the second adjusting member is provided with a restricting groove, a third threaded portion and a receiving portion; a first restricting member is received in the first receiving hole and the restricting groove; A second restricting member is accommodated in the second cavity; a third system is provided with a second cavity, a fourth screw part, and a guide groove; a second elastic member abuts against the first cavity The second body and the third body.

The first body rotates relative to the second body and displaces in one direction, the first body rotation system simultaneously drives the first adjustment member to rotate and displace in the same direction, and the first adjustment member synchronously drives the second adjustment member to rotate in the same direction , Because the third screw joint and The thread direction of the fourth threaded portion is different from the thread directions of the first threaded portion and the second threaded portion, and the second adjusting member drives the third body in the opposite direction of the second body Displacement, that is, when the total length of the torsion structure is shorter, the second elastic member has a longer length, and the torsion structure has a smaller torque value. When the total length of the torsion structure is longer, the torsion structure That is, it has a larger torque value, that is, the torque value is proportional to the total length of the torsion structure.
