Description

Torsion structure

The invention relates to a torsion structure, in particular to a torsion structure, in which the first rotating element can rotate in the third body and drive the second rotating element to rotate, so that the third screw part is in the The first screw portion rotates and displaces, and the end of the second rotating member pushes against the adjusting member to adjust the compression degree of the elastic member group.

According to my previous knowledge, the conventional torsion structure, such as US Patent No. 2733622, the structure includes: a body 10, the body 10 includes an action end 12 and a rod body 16; There is a first accommodating groove 20, the first accommodating groove 20 is in the shape of a circular groove, one end of the acting end 12 is provided with a threaded portion 30, the threaded portion 30 is in communication with the first accommodating groove 20, the threaded portion 30 is in the shape of an internal thread. The other end of the acting end 12 is provided with a through slot 56. The through slot 56 is in communication with the first accommodating slot 20. The first accommodating slot 20 is formed on the threaded portion 30 and Between the through slots 56, the through slots 56 and the threaded portion 30 are relatively positive and away from each other. The through slots 56 and the axis of the first receiving groove 20 and the threaded portion 30 are all on the same line. The through slot 56 is formed as a circular groove that penetrates; the rod body 16 is formed as a round rod body; a rotating member 50 is screwed to the threaded portion 30, and one end of the rotating member 50 is provided with a rotating member Part 34, the rotating part 34 is exposed outside the acting end 12 for rotation, so that the rotating part 50 is rotated and displaced at the screw part 30, and the other end of the rotating part 50 is provided with a fitting part 72, the fitting portion 72 is in communication with the first accommodating groove 20, the fitting portion 72 is relatively positive with the through slot 56, the opening of the fitting portion 72 is away from the rotating portion 34, The rotating member 50 is externally threaded; a driving rod 70 is penetrated and pivoted at the first accommodating groove 20 and the piercing groove 56, and a driving portion 64 is provided at one end of the driving rod 70 , The driving part 64 is exposed outside the through slot 56, the driving part 64 is in the shape of a quadrangular head, the other end of the driving rod 70 is sleeved on the sleeved part 72; a first clamping member 80, The first clamping member 80 is fixed at the first receiving slot 20. As shown in FIG. 3, the first clamping member 80 should be an integrally formed structure with the body 10, and the first clamping member A first set portion is provided at the axis of 80, the first set portion is opposite to the through slot 56, the first set portion is for the driving rod 70 to pivot, the first set portion It is in the form of a circular perforation. At the end of the first clamping member 80, there is a first engaging portion 86. The first engaging portion 86 is arranged in a ring shape. A second clamping member 90, the second The clamping member 90 is sleeved on the driving rod 70, the second clamping member 90 is driven to drive the driving rod 70 to rotate, the second clamping member 90 is provided with a second set portion 92, the first The second grouping portion 92 is opposite to the first grouping portion, the second grouping portion 92 is for the driving rod 70 to be sleeved, the second grouping portion 92 is non-circularly perforated, the second The assembling portion 92 should be in the shape of a quadrangular groove. At one end of the second clamping member 90 is a second bite portion 88. The second bite portion 88 is arranged in a ring shape. The second bite portion 88 It is engaged with the first engaging portion 86; an elastic element 96, and one end of the elastic element 96 is elastically pressed against the second clamping member 90; An elastic resisting piece 98, one end of the elastic resisting piece 98 is pressed against the rotating member 50, the other end of the elastic resisting piece 98 is pressed against the elastic element 96, and the elastic element 96 is elastically pressed against the second card Between the workpiece 90 and the resilient piece 98; a cover 24, which covers the opening of the first receiving slot 20 of the body 10, so that the first receiving slot 20 is closed, and the rotation The rotating portion 34 of the member 50 is protruding out of the cover 24, and as shown in FIG. 3, the threaded portion 30 should be provided at the cover 24. The cover 24 is round.

But the lack of this patent structure lies in:

1. The rotating member 50 rotates and displaces at the threaded portion 30, so that the elastic piece 98 is pressed against the elastic element 96 to adjust the torque value, but the torsion structure has only one way of adjusting the torque, and the expandability is insufficient.

2. As shown in FIG. 3 of the Patent Gazette, the first clamping member 80 and the body 10 are an integrally formed structure. When assembling, the driving rod 70 must first be sequentially threaded on the Through the slot 56, the first set portion of the first clamping member 80, the first accommodating slot 20 and the threaded portion 30, and then the second clamping member 90, the elastic element 96 and the The elastic piece 96 is fitted on the driving rod 70, and finally the rotating member 50 is screwed on the threaded portion 30, and the fitting portion 72 of the rotating member 50 is fitted on the driving rod 70, generally In other words, if it is a torsion joint structure with a larger specification, such as a quarter, the driving rod 70, the second clamping member 90, the elastic element 96, and the resilient piece 96 are larger and easier to group in sequence It is set in the first accommodating slot 20, but if the specification is small, such as the bisection specification or the post specification, the volume of the first accommodating slot 20 is not large, the driving rod 70, the second clamping member 90. The elastic element 96 and the resilient piece 96 are also smaller. After driving the driving rod 70 in the first receiving slot 20, each element is sequentially fitted on the driving rod The 70 series requires more assembly time, the system is Not easy to assemble.

3. The body 10 is integrally molded with the first clamping member 80, and the first clamping member 80 is required to be provided with the first engaging portion 86 arranged in a ring shape, the body 10 is not easy to form, the body 10 is There is a larger cost.

In view of the lack of the above-mentioned conventional structure, the inventor, after years of experience in manufacturing, production and design in related industries, finally has a torque structure product that can solve the conventional drawbacks.

In the conventional torsion structure, the rotating member rotates and displaces at the threaded portion, so that the elastic piece presses against the elastic element to adjust the torque value, and the expansibility is insufficient. In the torsion structure of the present invention, the first rotating member can rotate in the third body and drive the second rotating member to rotate synchronously, so that the third screw part rotates and displaces at the first screw part , The end of the second rotating member pushes against the adjusting member, so that the adjusting member adjusts the compression degree of the elastic member group.

The invention relates to a torsion structure, which includes: a first system provided with a first receiving groove, a first driving part, a first screwing part and a first receiving hole; an adjusting member; a first Retaining ring; an elastic part set; a driving part is provided with a second driving part and a connecting section; a first gear plate is provided with a first fitting part, a first engaging part and a second receiving hole; The second gear set is provided with a second fitting portion and a second engaging portion; a restricting member; a third body group includes a third body, a first rotating member and a second rotating member; the The third system is provided with a fourth container, a fifth container, a sixth container and a second abutment; the first screw A third fitting part is provided in the moving part; the second rotating part is provided with a third screwing part and a fourth fitting part.

The first rotating part can rotate in the third body and drive the second rotating part to rotate synchronously, so that the third screw part rotates and displaces at the first screw part, and the second rotating part The end part pushes against the adjusting member, so that the adjusting member adjusts the compression degree of the elastic member group.
