[0004] To overcome the above deficiencies, this utility model provides a detection device for seat belt buckle housings, which aims to improve the problem of being unable to detect the conformity of the shape and size of seat belt buckle housings, resulting in defective products and thus causing safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a detection device for a seat belt buckle shell, comprising a table, a detection mechanism on the top of the table, the detection mechanism being used to detect the shape and size of the seat belt buckle shell, and a pressing mechanism on the top of the table for pressing the seat belt buckle shell; The testing mechanism includes a base located at the top of the platform near the center. The top of the base is connected to a plurality of symmetrically distributed positioning posts and positioning sleeves. A seat belt buckle is slidably connected to the top of the positioning posts and positioning sleeves. A threaded hole is provided at the top of the positioning sleeve near the center. A sliding component is provided at the bottom of the seat belt buckle.

[0006] The above technical solution describes a device that primarily includes a platform serving as the foundation support for the entire device. A testing mechanism is located in the central area of ​​the platform's top, specifically for inspecting the shape and size of the seatbelt buckle's outer shell. Simultaneously, a pressing mechanism is installed on the top of the platform to apply pressure to the seatbelt buckle shell to complete the assembly inspection process. The testing mechanism includes a base, fixedly installed in the center of the platform's top. Multiple symmetrically arranged positioning posts and positioning sleeves are evenly distributed on the upper surface of the base.

The inner wall of these sleeves forms a precise fit with the outer wall of positioning post one, ensuring a smooth and stable sliding process. Positioning post two is also fixed at the bottom of the seat belt buckle, and its outer wall forms a sliding pair with the inner wall of positioning sleeve one, further enhancing the guiding stability of the sliding assembly. In addition, a square groove is opened at the bottom of the seat belt buckle, which together constitute a complete sliding mechanism system, ensuring that the seat belt buckle can move smoothly along a predetermined trajectory.

[0011] As a further description of the above technical solution: The limiting component includes a limiting block, the top of which is fixedly connected to the bottom of the pressing plate, and a circular hole for limiting is provided in the middle of the limiting block.

[0012] Through the above technical solution: the limiting component is mainly composed of a limiting block, which is made of high-strength metal material. Its top is firmly connected to the bottom of the pressing plate by welding, ensuring that there will be no loosening or falling off during long-term use. In the middle of the limiting block, a circular hole for limiting function is precisely machined, which ensures smooth assembly and reliable limiting function. The inner wall of the circular hole is polished, which effectively reduces frictional resistance and extends service life.

[0013] As a further description of the above technical solution: A connecting seat is attached to the top of the platform near the center. The top of the connecting seat is fixedly connected to the bottom of the base. The connecting seat is used to increase the height of the base.

[0014] Through the above technical solution: a cylindrical connecting seat is fixedly connected to the top of the tabletop near the middle position.

[0015] As a further description of the above technical solution: Multiple circular fixing blocks are fixedly connected to the top four sides of the tabletop, and a connecting column is connected to the other end of each circular fixing block. The circular fixing blocks and the connecting column are used to fix the tabletop to the operating surface.

[0016] The above technical solution involves the uniform distribution and fixed connection of multiple circular fixing blocks around the top four edges of the tabletop. Each circular fixing block has a cylindrical connecting column vertically connected to its other end. The circular fixing blocks and connecting columns together form a stable connection mechanism that firmly fixes the tabletop to the operating surface, ensuring that the tabletop will not shift or shake during use. This not only guarantees the stability of the structure but also facilitates installation, disassembly, and maintenance.

[0019] As a further description of the above technical solution: The outer wall of each knob is provided with anti-slip texture to facilitate control of the rotation of the threaded extrusion rod.

[0020] Through the above technical solution: the outer wall surface of the knob is evenly distributed with dense anti-slip texture, which not only increases the friction of the knob surface, but also effectively prevents fingers from slipping during operation, thereby ensuring that the user can more stably control the rotation of the threaded extrusion rod.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the seat belt buckle to be tested is aligned with the base and placed down. Then, the second positioning sleeve on the seat belt buckle will slide into the first positioning sleeve, and the second positioning post will slide on the surface of the first positioning post until the seat belt buckle falls down. At this time, the seat belt buckle is squeezed by the pressing plate, which realizes the ability to quickly test the shell shape and size of the seat belt buckle. 2. In this utility model, the threaded extrusion rod is aligned with the threaded hole one on the base. At this time, the knob is turned, and the knob will drive the connecting rod to rotate. Subsequently, the connecting rod will drive the threaded extrusion rod to rotate towards the inner wall of the threaded hole one. At the same time, the threaded extrusion rod slides along the circular hole on the limiting block, so as to achieve the function of continuously applying pressure during testing and preventing the seat belt buckle from popping up.

At the same time, the threaded extrusion rod 303 slides along the circular hole 3062 on the limit block 3061. Then, the threaded extrusion rod 303 will drive the pressing plate 301 to press the seat belt buckle 204 downward, thus achieving the function of continuously applying pressure during testing and preventing the seat belt buckle 204 from popping up.
