Description

Technical Field

[0001] The utility model relates to the technical field of torsion spring joints, in particular to a combined torsion spring joint. Background Art

[0002] Torsion springs are torsion springs. They are one of the most complex types of springs in terms of design principle. The types of springs vary greatly. The coils are either tightly wrapped or separated. They can withstand torsional loads (at right angles to the axis of the spring). The end of the spring can be wound into a hook or a straight torsion arm.

[0003] Patent document CN210598588U discloses a combined torsion spring joint. "The torsion spring joint in the patent document is connected to the joint by a torsion spring when in use, but lacks a limiting structure when in use, which causes the torsion joint to rotate excessively and become damaged. Utility Model Content

[0004] One purpose of the present application is to provide a combined torsion spring joint to solve the technical problem in the prior art that the torsion spring joint lacks a limiting structure during use, thereby causing the torsion joint to rotate excessively and become damaged.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined torsion spring joint, comprising a mounting plate, a first limit block is installed on one side of the mounting plate, a connecting shaft is installed on one side of the mounting plate, a mounting column is installed on one side of the connecting shaft, a limit assembly is installed at one end of the mounting column, the limit assembly is used to limit the use of the torsion spring joint, the limit assembly comprises a rotating shaft, a connecting plate and a second limit block, the rotating shaft is connected to the mounting column, the connecting plate is connected to one end of the mounting column, and the second limit block is installed on the top of the connecting plate.

[0006] Preferably, a first through hole is formed through the middle of the mounting plate, a second through hole is formed through the middle of the connecting shaft, and the second through hole corresponds to the first through hole.

[0007] Preferably, a mounting groove is symmetrically provided on one side of the connecting shaft, and a connecting groove is provided on an inner wall of one side of the mounting groove.

[0008] Preferably, a sliding plate is movably mounted on the inner wall on the other side of the mounting groove, and a pulling plate is mounted on the front side of the sliding plate.

[0009] Preferably, a fixing screw is installed on the front side of the sliding plate, the fixing screw is located on one side of the pulling plate, and the fixing screw is threadedly connected to the back inner wall of the mounting groove.

[0010] Preferably, a limiting groove is provided on the outer side of the mounting column.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the first through hole and the second through hole enable the mounting column to be rotatably mounted on one side of the connecting shaft through the rotating shaft for use. When the torsion spring is mounted on the joint for use, the mounting column will rotate, thereby rotating the second limit block installed at one end through the connecting plate. When the second limit block contacts the first limit block, the mounting column cannot rotate, thereby preventing the torsion spring joint from being damaged due to excessive rotation.

[0013] 2. In the utility model, when the torsion spring is installed on the outside of the mounting column, the protruding parts at both ends of the torsion spring are inserted into the inside of the mounting groove through the connecting groove. Under the action of the limiting groove, the torsion spring can be stably located on the outside of the mounting column for use. When the torsion spring needs to be disassembled, in order to facilitate the disassembly of the two ends of the torsion spring, the sliding plate can be movable by rotating the fixing screw, and the sliding plate is pulled to one side by the pulling plate, so that the mounting groove has a larger space, which is convenient for disassembling the two ends of the torsion spring connected inside the connecting groove.
