The mounting cylinder is arranged in the drainage cavity 103 and is in sealed connection with the seat body. On the one hand, it ensures that the environment in the containing cavity 106 is not affected by external moisture, providing a stable working environment for the components contained therein; on the other hand, the drainage cavity 103 and the containing cavity 106 are independently arranged and organically combined, realizing the drainage function without occupying additional space, making the overall structure more compact and reasonable.

When the device is applied in harsh environments such as high humidity and high dust, the sealing ring relies on the strong sealing pressure generated by the interference fit to ensure the reliable connection between the optical glass cover plate and the containing cavity 106, and maintain the normal operation of the device.
