A plurality of circular holes are provided on the other side of the bottom shell, and the second waterproof ring is installed in the plurality of circular holes. The PCB board is installed on the first waterproof ring, and the waterproof bolt passes through the second waterproof ring, the bottom shell, and the PCB board in sequence and is arranged in the first waterproof ring.

[0007] Preferably, a plurality of positioning blocks are integrally formed at the bottom of the groove, and a plurality of positioning holes penetrating the positioning blocks are formed on the surface of the first waterproof ring.

[0008] Preferably, the first waterproof ring and the second waterproof ring are made of soft material.

[0009] Preferably, a support and protection frame is provided on the lower surface of the bottom shell, and a plurality of water flow troughs are provided in the support and protection frame.

[0010] Preferably, a heat dissipation through hole is further provided on the side surface of the bottom shell, and a waterproof plate is provided on the upper end of the heat dissipation through hole.

[0011] Preferably, the bottom shell is further provided with fixing holes for fixing the bottom shell.

[0012] Preferably, a moisture-proof sealing gasket is further provided on the lower surface of the bottom shell.

[0013] Preferably, a power line outlet and a signal cable outlet are provided on the bottom shell, and the power line outlet and the signal cable outlet are designed with a circular fence, and a waterproof groove is provided on the fence.

[0014] Preferably, the power cord outlet and the signal cable outlet are equipped with corresponding power cord outlet waterproof rear covers and signal cable outlet waterproof rear covers.

[0015] Compared with the beneficial effects of the existing technology, the product is waterproofed by using a waterproof ring, a bottom shell and waterproof bolts, without the need to inject sealing glue. The product needs to be able to be placed outdoors as a whole, with good waterproof performance, and be able to ensure that the waterproof ring is of universal size and fully functional, so that it has good waterproof effect and good market application value.
