One end of the strip rib 11 is integrally formed with a large threaded seat 111. The other end of the strip rib 11 is integrally formed with a large threaded seat 111. A small threaded seat 112 is integrally formed at the end, and the rear housing 2 is fastened and assembled with the front housing 1 through the cooperation of the first hexagonal countersunk screw 3 and the large threaded seat 111. The sealing ring 22 and the rear housing 2 are both in contact with the front housing 1. A step structure 12 is provided at the projection end of the front housing 1, and a light-transmitting plate 4 is sealed on the step structure 12.

The structural baffle 5 is fastened and assembled with the front housing 1 through the cooperation of screws and the small threaded seat 112;

[0042] In one aspect of this embodiment, both the front and rear housings have a columnar structure, and the front and rear housings are smoothly connected at their outer circumferential surfaces after assembly. This not only saves space in the projector housing but also improves its aesthetics through the regular columnar structure. Furthermore, since the front and rear housings are smoothly connected at their outer circumferential surfaces after assembly, the outer edges of the housings are smoothed, making it less likely for the sharp corners of the housings to scratch viewers, thereby improving their safety.
