Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of torsion springs, in particular to a buckle torsion spring mechanism for a shaft. Background Art
[0002] The design principle of torsion spring (torsion spring) is relatively complex and has many forms. The structure of the more commonly used torsion spring generally includes a torsion spring body of a columnar spring structure and two ends for bearing force; the coils of the torsion spring body are either tightly wrapped or separately wrapped, which can be suitable for the load generated by the torsion moment, and the direction of the torsion moment is generally at right angles to the spring axis; in order to be able to cooperate with the components applying the torsion moment, the two ends of the torsion spring can be wound into hooks or straight torsion arms.
[0003] In some workpiece combinations such as jacks, a torsion spring is needed to fix the workpiece. In the prior art, the torsion spring does not have a locking effect and is prone to fall off naturally, causing the workpiece to fall apart. Therefore, the existing torsion spring structure needs to be improved. Utility Model Content
[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a buckle torsion spring mechanism for a shaft.
[0005] The utility model proposes a shaft-use snap-on torsion spring mechanism, comprising a torsion spring body 1, a first extension portion 2 and a second extension portion 3, wherein the first extension portion 2 and the second extension portion 3 are located in the same plane and are parallel to each other, the first extension portion 2 and the second extension portion 3 are oriented in the same direction, and the end of the second extension portion 3 has a bending portion 301 bent toward the first extension portion 2, and an angle is formed between the bending portion 301 and the second extension portion 3, and the angle is an acute angle.
[0006] Preferably, the angle between the bending portion 301 and the second extending portion 3 is between 20° and 70°.
[0007] Preferably, the middle part of the first extension portion 2 has a bending angle 4, and the bending angle 4 is located between the torsion spring body 1 and the bending portion 301. The bending angle 4 has two folded edges, the folded edge away from the bending portion 301 is the first folded edge 401, and the folded edge close to the bending portion 301 is the second folded edge 402.
[0008] Preferably, the bending angle 4 of the first extension portion 2 bends in a direction away from the second extension portion 3 .
[0009] Preferably, the end of the bending portion 301 is located between the first folded edge 401 and the second folded edge 402 of the bending angle 4.
[0010] Preferably, the bending angle 4 of the first extension portion 2 bends toward a direction approaching the second extension portion 3 .
[0011] Preferably, the end of the bent portion 301 abuts against the side wall of the second folded edge 402 .
[0012] Preferably, the end of the bent portion 301 abuts against the side wall of the end of the first extending portion 2 .
[0013] Preferably, the end of the bent portion 301 points to the end of the first extending portion 2 , and a gap is left between the end of the first extending portion 2 .
[0014] In the utility model, a shaft-use snap-on torsion spring mechanism is proposed. When the first extension portion is inserted into the hole of the workpiece, it will touch the outer wall of the bent portion, causing it to deform. After the angle between the bent portion and the second extension portion gradually decreases, the hole of the workpiece passes through the bent portion, and the bent portion rebounds and continues to contact with the first extension portion, thereby locking the torsion spring through the hole of the workpiece. The angle between the bent portion and the second extension portion is an acute angle, and the torsion spring cannot fall off easily when it moves in the opposite direction to exit the hole. The second bending angle can play an anti-falling function. When the bent portion contacts the second folded edge of the bending angle, the bent portion will have an additional contact portion at the end of the first extension portion, which can further enhance the anti-falling function and prevent it from falling off naturally.
