Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a bracket with an angle compensation mechanism. Background Art

[0002] A retractor is a device used to wind and store rolled objects such as wire, rope, and pipes. It has a wide range of applications, including the winding of various materials and the application of safety belts. Typically, a retractor requires a bracket for positioning and installation to ensure stable operation.

[0003] The bracket structures used in some traditional retractors are mostly fixed brackets, which are installed directly by welding or bolting. The structure does not have the angle compensation function and therefore cannot provide buffering. After the retractor frame is subjected to high-frequency force, its fatigue resistance decreases and it is prone to damage. Utility Model Content

[0006] As a further description of the above technical solution:

[0007] The fixed bracket is provided with a movable notch at a position corresponding to the rotating bracket.

[0008] As a further description of the above technical solution:

[0009] The rotating frame and the fixing recess are arranged in a nested rotational fit.

[0010] As a further description of the above technical solution:

[0011] The position where the rotating shaft meets the inner wall of the fixed recess is positioned and installed via a bearing.

[0012] As a further description of the above technical solution:

[0013] The rack frame is fixedly connected with a limiting slide block, and a limiting slide groove is provided on one side of the second inner wall of the fixed groove. The limiting slide block and the limiting slide groove are nested and slidably connected.

[0014] As a further description of the above technical solution:

[0015] The cross sections of the limiting sliding block and the limiting sliding groove are both T-shaped.

[0016] The utility model has the following beneficial effects:

[0017] The bracket with the angle compensation mechanism can stably install the retractor frame and the fixed bracket together through the arrangement of structures such as the rotating frame, the rotating shaft, and the fixed recess. In conjunction with the arrangement of structures such as the gear, the rack frame, the damper, the piston column, and the buffer spring, the retractor frame can be smoothly tilted and rotated after being subjected to force, thereby achieving smooth angle compensation, and can be smoothly reset after being released from the stressed state, effectively enhancing the flexibility and safety of the retractor frame, and avoiding the situation in which the fatigue resistance of the rigid connection form decreases and is easily damaged after the retractor frame is subjected to high-frequency force.
