Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and particularly relates to a seat belt bearing with an anti-dropping structure. Background Technique

[0002] When the seat belt is retracted into the bearing, the dust on the seat belt will enter the bearing along the notch, causing wear to the bearing, increasing the clearance of the rolling surface, deforming the parts, and making the bearing prone to falling off. Abnormal wear on the mating surfaces of the inner and outer rings of the bearing: Under normal use conditions, the wear is not significant. However, when foreign objects enter the bearing, the lubrication is insufficient, or the lubricating oil deteriorates, rapid wear is likely to occur, increasing the clearance of the rolling surface, deforming the parts, and disrupting the normal operation of the bearing and related parts.

[0003] The existing device mainly installs a cleaning component on the top of the bearing housing to prevent foreign objects from entering. The prior art is mostly similar to a seat belt bearing with an anti-dropping structure. The structure of the patent No. CN213565790U includes a bearing housing. A square hole is opened on the top side wall of the bearing housing. Two symmetrically distributed plastic plates are rotatably connected to the top side wall of the bearing housing through a torsion rotating shaft. The other ends of the two plastic plates are fixedly connected with metal plates, and a plurality of through holes are opened on the side walls of the two metal plates. The utility model can complete the collection of dust, but there are still places where the device can be optimized.

[0004] The existing device mainly fixes the cleaning brush on the top of the bearing housing, making it difficult for some devices to quickly assemble the brush buckle on the outer wall of the seat belt, resulting in a waste of a large amount of assembly time. At the same time, some devices mainly fix the brush through structures such as clamping plates, making it difficult for some devices to quickly disassemble the brush buckle, resulting in some devices being inconvenient to replace the brush, reducing the working efficiency and practicability of the device. Therefore, in order to solve the above problems, a seat belt bearing with an anti-dropping structure is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a seat belt bearing with an anti-dropping structure, so as to solve the problems in the prior art mentioned in the above background technique, that is, the existing device mainly fixes the cleaning brush on the top of the bearing housing, making it difficult for some devices to quickly assemble the brush buckle on the outer wall of the seat belt, resulting in a waste of a large amount of assembly time. At the same time, some devices mainly fix the brush through structures such as clamping plates, making it difficult for some devices to quickly disassemble the brush buckle, resulting in some devices being inconvenient to replace the brush.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A seat belt bearing with an anti-detachment structure, including a bearing housing, a fixing seat is fixedly connected to the middle of the top of the bearing housing, a seat belt body is placed inside the bearing housing, a buckle is sleeved on the outer wall of the seat belt body, a brush buckle is inserted on the outer wall of the seat belt body above the bearing housing, and a connecting frame is fixedly connected to the outer wall of the brush buckle;

Through the limiting ring, sliding seat, clamping sleeve, clamping tongue and clamping hole in the assembling mechanism of the present utility model, the brush buckle is sleeved on the outer wall of the seat belt body through the connecting frame, and the left side of the connecting frame is inserted into the clamping sleeve of the fixing seat. Push the sliding seat to the left to drive the clamping tongue to be clamped in the clamping hole, so that the sliding seat drives the right clamping sleeve to be sleeved on the right side of the connecting frame, realizing the assembly and fixation of the brush buckle, enabling some devices to quickly assemble the brush buckle on the seat belt outer wall, saving a large amount of assembly time, and improving the convenience and practicality of the device.

[0015] 2. The utility model realizes the disassembly of the brush buckle through structures such as the wedge-shaped slider, the push bar, the toggle, the limit rod, the limit seat and the spring in the disassembly mechanism. By toggling the toggle to the right, the push bar and the limit rod are driven to slide and compress the spring in a limited manner. At the same time, the push bar drives the wedge-shaped slider to slide synchronously, so that the wedge-shaped slider drives the tongue to disengage from the locking hole, realizing the disassembly of the brush buckle. This enables some devices to quickly disassemble the brush buckle, facilitating the replacement of the brush buckle, and enhancing the convenience and practicality of the device.
