Description

Torsion structure

The invention relates to a torsion structure, especially a torsion structure, in which the first body, the second threaded portion, the third threaded portion and the third body actuate the second elastic member to make the first body The rotation and displacement and the action of actuating the second elastic member have the effect of saving labor or time.

According to my previous knowledge, the conventional torque wrench structure is also a patent case assigned by me, such as the US patent case number: US8863624B2, Taiwan patent case application number: 103215530, certificate number: M492808, patent name: with locking device The structure of the patent case 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 disposed at the outer periphery of the second end 12 of the main rod body 10, and generates relative axial movement along the main rod body 10 between a locked position and an unlocked 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 lack of this conventional torque structure lies in:

1. Please supplement as shown in Fig. 4 that the adjusting screw 31 is set in the adjusting grip 30. When the adjusting grip 30 is rotated and displaced relative to the main rod body 10, the adjusting grip 30 The adjustment screw 31 is driven to rotate and shift synchronously. The adjustment screw 31 is helically displaced in the second end 12, and the adjustment screw The member 31 actuates the elastic member 40 synchronously, that is, the adjusting grip 30, the adjusting screw member 31 and the elastic member 40 are all operated as a unit.

2. When the adjusting screw 31 is spirally displaced in the direction of the first end 11, the pressing member 41 is pressed against the torsion adjusting elastic member 40, so that the torsion adjusting elastic member 40 is more compressed to adjust and increase the torsion force When the torque value of the wrench is adjusted, the adjustment grip 30 is also displaced toward the first end 11. The overall length of the torque wrench is reduced. That is, when the torque adjustment elastic member 40 is in the most compressed state, the torque wrench The torque value is the largest, but the overall length of the torque wrench is the shortest. 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 is not in line with demand.

3. Please refer to Figures 6 to 8 of the US Gazette. When you want to adjust the torque value, move the locking ring 61 in the direction of the adjustment grip 30 to make the locking device 60 slide To the non-locking 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 at the non-locking position, The positioning bead 65 is not pushed up 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 grip 30 can be opposite The main lever body 10 rotates, but when the adjusting handle 30 rotates relative to the main lever body 10 to adjust the torque value, there is no prompt sound when the adjusting handle 30 rotates, to For understanding the current torque value status of the torque wrench, the control is not convenient.

4. The positioning groove 13 is hidden in the adjusting handle 30. When the adjusting handle 30 rotates, the positioning bead 65 may not be aligned with one of the positioning grooves 13, and 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 locking position, which is inconvenient during operation.

In view of the lack of the above-mentioned conventional structure, the inventor took many years to engage in related industries The manufacturing, production and design experience finally came out with a torsion structure product that can solve the conventional drawbacks.

In the conventional torsion structure, the adjustment grip, the adjustment screw and the elastic member are all operated as one without change. In the torsion structure of the present invention, the first body, the second threaded portion, the third threaded portion and the third body actuate the second elastic member to rotate and displace the first body and actuate the second The elastic parts have the effect of saving labor or time.

A torsion structure, which includes: a first body portion is provided with an accommodating groove; a second system is provided with a first accommodating hole; a fixed seat assembly includes a fixed seat; the fixed seat is provided with a first A screwing part; an adjusting group includes an adjusting part; the adjusting part is provided with a second screwing part to screw with the first screwing part, rotating the first body to rotate relative to the second body When shifting, the adjusting member is spiral and displaced. The other end of the adjusting member is provided with a third screwing portion, which is the same as or different from the second screwing portion; There is a first accommodating groove, a fourth screwing portion and a guide groove; a restricting member is accommodated in the first accommodating hole and the guide groove; a second elastic member is elastically pressed against the second body With the third body.

The adjusting member is provided with the second threaded portion and the third threaded portion, and the first body, the second threaded portion, the third threaded portion and the third body can actuate the second elastic member, so that The action of rotating and shifting the first body and the action of the third body actuating the second elastic member has a labor-saving or time-saving effect, that is, the first body rotates When there is more displacement, the second elastic element has less action, and the torsion structure has a labor-saving effect. When the first body rotates and has less displacement, the second elastic element has more action and has a time-saving effect. , The threads of the second threaded portion and the third threaded portion can be changed according to the requirements of labor saving or time saving.
