Technical Field

[0001] The utility model belongs to the technical field of torsion spring installation, in particular to a torsion spring joint assembly. Background Art

[0002] Torsion spring is a type of spring with the characteristic of twisting deformation. It is usually made of round wire. Its main function is to provide elasticity and torque. It is often used in various mechanical equipment and industrial production. The elastic force and torque can play a role in smooth, precise and stable effects on various mechanical equipment and industrial production. It usually requires a connector assembly to fix it to the corresponding structure. In order to ensure the safety of the use process, it needs to be able to be connected firmly.

[0003] Although the existing components have high connection stability, the operation of connecting the torsion spring joint is relatively complicated and inconvenient to operate.

[0004] For example, a high-strength torsion spring joint device with a Chinese utility model application number of 201920342060.X includes a joint part and a torsion spring mounting part, wherein the torsion spring mounting part is arranged below the joint part, and the torsion spring mounting part is formed integrally with the joint part through a connecting part above the torsion spring mounting part, and multiple groups of triangular reinforcing ribs are arranged equidistantly on the outer side of the connecting part, and the top of the triangular reinforcing ribs extends to the bottom of the joint part and is welded to the joint part, and the bottom of the triangular reinforcing ribs is welded to the torsion spring mounting part, and a mounting groove for mounting a rotating tube is arranged in the middle of the joint part. The operation of connecting the torsion spring joint by this assembly is relatively complicated and inconvenient to operate. Utility Model Content

[0005] The purpose of the utility model is to provide a torsion spring joint assembly to solve the problems raised in the background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a torsion spring joint assembly, comprising:

[0007] A connecting portion and a mounting portion installed at the bottom of the connecting portion for mounting a torsion spring joint;

[0008] The mounting portion includes a plurality of elastic mounting plates distributed in a ring shape and welded to the bottom of the connecting portion, a mounting ring is screwed between the outer sides of the plurality of elastic mounting plates, the outer wall of the mounting ring is symmetrically integrally formed with two holding pieces, the outer wall of the connecting portion is symmetrically provided with two fixing holes, and tightening bolts are screwed in the fixing holes, a connecting plate is integrally formed on the top of the connecting portion, and two connecting holes are symmetrically provided on the top of the connecting portion.

[0009] In a further embodiment, the mounting ring and the holding member, and the connecting portion and the connecting plate are all cast as an integral structure.

[0010] In a further embodiment, a rubber film is bonded to the inner side of the elastic mounting sheet, and the edges of the rubber film and the elastic mounting sheet are flush.

[0011] In a further embodiment, the connecting portion is flush with the top of the connecting plate.

[0012] In a further embodiment, a washer is sleeved on the side wall of the abutment bolt, and the washer is supported between the head of the abutment bolt and the corresponding side of the connecting portion.

[0013] In a further embodiment, the corners of the gripping member are arc-shaped structures.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The torsion spring joint assembly, although the existing solution improves the stability of the torsion spring joint connection through multiple structural coordination, requires multiple welding operations, which makes the operation more complicated. The present solution completes the connection by twisting the mounting ring to tighten the torsion spring joint through multiple elastic mounting plates, and then twisting the tightening bolt to tighten the joint to reinforce it. The operation of connecting the torsion spring joint is relatively simple and more convenient to operate.

[0016] The torsion spring joint assembly is simpler and more convenient to operate for connecting the torsion spring joints. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] In order to make the connection of the torsion spring joint simpler and more convenient to operate, such as Figures 1 to 3 A torsion spring joint assembly shown includes: a connecting part 1 and a mounting part installed at the bottom of the connecting part 1 for mounting the torsion spring joint, the mounting part includes a plurality of elastic mounting pieces 2 distributed in a ring shape and welded to the bottom of the connecting part 1, a rubber film 10 is bonded to the inner side of the elastic mounting piece 2, and the edges of the rubber film 10 and the elastic mounting piece 2 are flush, the rubber film 10 can increase the friction with the contact surface of the joint, thereby improving the stability of the torsion spring joint after installation and fixation.

[0027] A mounting ring 3 is screwed between the outer sides of multiple elastic mounting plates 2. By screwing the mounting ring 3 upward to gradually tighten the multiple elastic mounting plates 2, the joint of the torsion spring can be installed and fixed. The outer wall of the mounting ring 3 is symmetrically cast with two holding parts 9, and the holding parts 9 are used to conveniently apply force to twist the mounting ring 3. The corners of the holding parts 9 are arc-shaped structures to improve the gripping feel. The outer bottoms of the two symmetrical elastic mounting plates 2 are both cast with limiting blocks 8 to prevent the untightened mounting ring 3 from accidentally falling off.

[0028] Two fixing holes 4 are symmetrically provided on the outer wall of the connecting part 1, and a clamping bolt 5 is threaded in the fixing hole 4. After the joint of the torsion spring is inserted, it will extend to the inner side of the connecting part 1. Tightening the clamping bolt 5 can abut the joint to improve the stability of the connection. A washer (not shown in the figure) is provided on the side wall of the clamping bolt 5, and the washer is supported between the head of the clamping bolt 5 and the corresponding side of the connecting part 1 to prevent the clamping bolt 5 from being screwed in too tightly and becoming inconvenient to unscrew. A connecting plate 6 is integrally cast on the top of the connecting part 1. The integrally cast structure has high strength and is not easy to break or damage. The top of the connecting part 1 is flush with the top of the connecting plate 6. Two connecting holes 7 are symmetrically provided on the top of the connecting part 1. Bolts are threaded in the connecting holes 7 to fix the component to the external structure.

[0029] How it works

[0030] The torsion spring joint assembly inserts the torsion spring joint between multiple elastic mounting plates 2, and the tail of the joint extends to the inner side of the connecting part 1. Then, the mounting ring 3 is rotated upward by applying force through the holding piece 9 to gradually tighten the multiple elastic mounting plates 2, so that the torsion spring joint can be installed and fixed. Then, the tightening bolt 5 can be tightened to press against the corresponding side of the joint to improve the stability of the connection. Finally, the bolt is screwed into the connecting hole 7 to fix the assembly to the external structure.
