Description

Torsion structure

The present invention is related to a torsion structure, especially in a torsion structure, the restricting member can be moved to an unrestricted position or a restricting position on the first body, so that the restricting member does not restrict or restrict the drive assembly , To make the drive group in an unrestricted or restricted state relative to the first system to control whether the drive group has a torsion release effect relative to the first body. When the restricting member is in an unrestricted position, the torsion force The structure has a torsion effect. When the restricting member is located at the restricting position, the driving group has no torsion tripping effect relative to the first body. The torsion structure can be used as a general connecting rod structure.

According to our previous knowledge, the conventional torsion structure is also the previous patent application that I applied for. Taiwan patent application number: 108114314, certificate number: I683730, patent name: torsion structure, please supplement with the first figure of the bulletin. , Its structure is: a torsion structure, which includes: a first body 10; an elastic member group 20; a driving member 30; a first gear plate 40; a second gear plate 50; a tip body 57; A first ring 58; a second ring 59; at least one restricting member 60; a second body 70 and a screw member 80.

However, the shortcomings of this conventional patent structure are:

The first body 10 is driven to rotate, the first body 10 drives the first chainring 40 to rotate, and the first chainring 40 drives the second chainring 50 and the driving member 30 to rotate so as to rotate and fit on the For the tool part at the second driving part 31, when the torque of the rotation is too large, the first engaging part 42 is engaged with the second engaging part 42 The joint 52 will disengage from each other. The second chainring 50 drives the driving member 30 to shift in the direction of the first driving part 12 to compress the elastic member group 20, and has a torsion release function, but the torsion structure No control structure is provided to limit the torsion release and displacement between the driving member 30, the first chainring 40 or the second chainring 50, that is, the torsion structure only has the function of torsion, The scalability is insufficient.

In view of the above-mentioned shortcomings of the conventional structure, the inventors have used years of experience in manufacturing, production and design in related industries to finally have a product with a torsion structure that can solve the drawbacks of the conventional structure.

The conventional torsion structure only has the function of torsion, and the expandability is insufficient. In the torsion structure of the present invention, the restricting element can be moved to an unrestricted position or a restricting position on the first body, so that the restricting element does not restrict or restrict the driving group, so that the driving group is relative to the first body. The system is in an unrestricted or restricted shape to control whether the driving group has the effect of torsion release relative to the first body. When the restricting member is in an unrestricted position, the torsion structure has a torsion function. When the member is in the restricted position, the driving group has no torsion release function relative to the first body, and the torsion structure can be operated as a general connecting rod structure.

The present invention relates to a torsion structure, which includes: a first system provided with a first container, at least one first container and a first restricting portion; an elastic element group; a driving group including a driving element , A first chainring and a second chainring; the driving member is provided with a first driving part; the first chainring is provided with a first meshing part; the second chainring Is provided with a second engaging portion and at least one first guide groove; at least one transmission member enables the first system to drive the second ring gear to rotate; a second body set; a restricting member can be attached to the first body Actuate to an unrestricted position or a restricted position, so that the drive group is in an unrestricted state relative to the first system and has the effect of torque jump, or the drive group is restricted relative to the first system without torsion jump脱functionality.

The restricting element can be moved to an unrestricted position or a restricting position on the first body, so that the restricting element does not restrict or restrict the drive group, so that the drive group is in an unrestricted state or relative to the first system. The restricting shape is used to control whether the driving group has the function of torsion jump-off relative to the first body. When the restricting member is in the non-restricting position, the torsion structure has a torsion effect. When the restricting member is in the restricting position, the The driving group is limited by the restricting member, and the driving group has no torsion release function relative to the first body system. The torsion structure can be operated as a general connecting rod structure. The torsion structure has two different functions. The torsion structure is expandable.
