Description

Torsion structure

The present invention is related to a torsion structure, especially in a torsion structure, the first restricting member can be moved on the second body, so that the second restricting member is aligned with the second restricting portion or the third restricting portion, so that The second restricting member is not clamped or clamped at the first restricting portion, the third body is in an unrestricted or restricted shape relative to the second system, and the torque structure is a torque wrench or a general wrench structure.

According to our previous knowledge, the conventional torsion structure is also a patent case assigned by us. For example, the US patent number: US8863624B2, the Taiwan patent application number: 103215530, the certificate number: M492808, the patent name: with a locking device Torque wrench, the structure of the patent is: a torque wrench with a locking device, which includes: a hollow main rod body 10; a tool part 20; an adjustment grip 30; a torque adjustment elastic member 40; a clutch Component 50; and a locking device 60, wherein when in the locked position, the positioning bead 65 is pushed by the pushing surface 612 and can be pressed against the positioning groove 13 to restrict the adjustment handle 30 Relative to the rotation of the main rod body 10, when in the non-locking position, the C-shaped buckle 63 is engaged with the ring groove 614, so that the positioning bead 65 can move between the accommodating groove 611 and the positioning groove 13 In this way, the adjusting handle 30 can rotate relative to the main rod body 10, and the locking ring 61 can make a sound when adjusting and switching between the locked position and the non-locked position. This is a structure.

But the lack of the torque wrench of the locking device of this conventional tool lies in:

As shown in Figure 3 of the Bulletin, when the locking device 60 is in the locked position, the adjusting handle 30 rotates on its own axis to drive the main rod body 10 and the tool part 20, so that the main rod When the body 10 and the tool part 20 rotate on their own axis, the clutch assembly 50 enables the tool part 20 to have the function of torsion release relative to the main rod body 10, but the torque wrench structure does not have any control The structure limits the function of the clutch assembly 50, so that the torque wrench structure has only a torque function, and its expandability is insufficient.

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 torque wrench of the conventional locking device, the torque wrench structure has only a torque function, and its expandability is insufficient for a single operation mode. In the torque structure of the present invention, the first restricting member can be attached to the second body The upper action makes the second restricting part aligned with the second restricting part or the third restricting part, so that the second restricting part is not locked or locked at the first restricting part, so that the The three bodies are in an unrestricted or restricted shape relative to the second system. The torsion structure is a torque wrench structure or a general wrench structure for operation and use, and is expandable.

The present invention relates to a torsion structure, which includes: a first system with a first container; a second system with a second container, a first pivot and two restricting grooves; a first elasticity Pieces; a third system is provided with a driving part, a pivot seat, a second pivot part and a first restriction part; a restriction set can be moved to a first body on the second body An unrestricted position or a restricted position, so that the third body is in an unrestricted shape with respect to the second system and has a torsion release function or is in a restricted shape without a torsion release function. The restriction group includes a first The limiting member and two second limiting members; the first limiting member is assembled on the second body, the first limiting member is provided with a second limiting portion and a third limiting portion; the second limiting member is accommodating Set at the restriction slot.

The restriction group can be moved to an unrestricted position or a restricted position on the second body, so that the third body is in an unrestricted or restricted shape relative to the second system, so as to control the third body relative to the first Whether the two bodies have the function of torsion release, the restriction group is located in an unrestricted position, the torque structure has the function of a torque wrench, when the restriction group is located in the restriction position, the third system is limited to the restriction group, The abutting part cannot swing and displace, the third body has no torsion tripping effect relative to the second body, and the torsion structure can be operated as a general wrench structure. The first restricting member can act on the second body, so that the second restricting member is aligned with the second restricting portion or the third restricting portion, so that the second restricting member is not jammed or jammed. It is made at the first restricting portion so that the third body is in an unrestricted or restrictive shape relative to the second system. The torsion structure is a torque wrench structure or a general wrench structure for operation and use.

8. When the control collar 31 is in the unlocked position, the first body 10 can rotate relative to the second body 20, so that the positioning member 34 can be displaced on the second body 20 to be positioned in any positioning groove At 25, when the positioning member 34 moves from one positioning groove 25 to the next positioning groove 25, the positioning member 34 is pushed by the outer peripheral surface of the second body 20 to open the second ring body 35, When the positioning member 34 is aligned with the next positioning groove 25, the positioning member 34 receives the elastic restoring force of the second ring body 35 and is accommodated in the next positioning groove 25, it will enter the positioning groove 25. Sound, the re-accommodation between the positioning member 34 and each positioning groove 25 will generate a positioning prompt sound for understanding the adjusting torque of the adjusting member 50 It can also be known that the positioning member 34 has been accommodated in one of the positioning grooves 25. If the torque structure has been adjusted to the required torque value, it is convenient to return the control collar 31 to the lock Solid position.

9. When the positioning member 34 is further accommodated in the positioning groove 25, it is the elastic restoring force of the second ring body 35, and is accommodated within the limit of the elastic restoring force of the second ring body 35. The displacement path is based on the arc of the positioning groove 25. Therefore, the sound of the positioning member 34 is more reliable. The displacement of the positioning member 34 is restricted by the second ring body 35. The sound can also be smoother.

10. The positioning groove 25 is hidden in the first body 10, so it can be known by sound that the positioning member 34 has been accommodated in the positioning groove 25 of the required torque value, and the sound can be used to judge when operating. It is practical.

11. When the control collar 31 moves on the first body 10 in the opposite direction of the second body 20 to the unlocked position, the second elastic member 32 is pressed by the second abutting edge 312 to form In a compressed shape, the first ring body 33 is stretched out and abuts against the second tapered groove 316, so that the control collar 31 is positioned in the non-locking position, and the hand does not need to be pushed against the control all the time. The collar 31 is convenient for rotating the first body 10 by hand. When the first ring body 33 expands outwards and abuts against the second tapered groove 316, the first ring body 33 expands outwards to have a sound. The first ring body 33 has uttered and it is determined that the control collar 31 is in the unlocked position.

12. The first body 10 has a sound when it rotates relative to the second body 20, the control ring 31 also has a sound when it is in the unlocked position, and both of the two torque adjustment actions have a sound prompt sound.
