[0026] This utility model provides a fastening bolt for automotive headlights. Please refer to [link / reference]. Figure 1-5 The bolt end 1 is fitted into the lamp housing base 100, and the bolt rod 2 is inserted into the body sleeve 200 and engaged with the body sleeve 200. The bolt end 1 includes a fitting part 101, an anti-rotation part 102, and a positioning head 103. The fitting part 101 and the anti-rotation part 102 are interference-fitted into the lamp housing base 100 to lock the axial displacement and rotation of the fastening bolt and the lamp housing base 100. At least one slot 201 is machined on the bolt rod 2, and the slot 201 is adapted to the retaining ring 300 in the body sleeve 200. When the bolt rod 2 is inserted into the body sleeve 200, the slot 201 engages with the retaining ring 300, so that the fastening bolt is fixedly connected to the body sleeve 200, thereby positioning and installing the vehicle lamp on the vehicle body.
[0027] Specifically, the fitting part 101 is disc-shaped and is adapted to the fitting groove in the lamp housing base 100, and the fitting part 101 and the fitting groove in the lamp housing base 100 are interference fit.
[0028] Furthermore, the positioning head 103 is located at the center of the fitting part 101 and is adapted to the positioning groove in the lamp housing base 100, so that the bolt end 1 of the fastening bolt is positioned and installed with the lamp housing base 100.
[0029] Specifically, the anti-rotation part 102 is located on the side of the fitting part 101 away from the positioning head 103, and is adapted to the anti-rotation groove in the lamp housing base 100 to prevent the fastening bolt from rotating inside the lamp housing base 100.
[0030] In this embodiment, the anti-rotation part 102 has a polygonal structure, which can prevent the fastening bolt from rotating during installation or disassembly.
[0031] For details, please refer to Figure 6 and Figure 7 The bolt rod 2 has multiple slots 201, which are spaced apart along the axial direction of the bolt rod 2. Each slot 201 corresponds to a multiple retaining ring 300 in the body insert 200. Each slot 201 corresponds to a ball head 202. When the bolt rod 2 is inserted into the body insert 200, the ball head 202 guides the retaining ring 300 to slide into the corresponding slot 201.
[0032] The multi-slot 201 improves the tightness of the fastening and is easier to install or remove compared to threaded connections.
