DETAILED DESCRIPTION

[0022] like Figure 1-2 As shown, an explosion-proof housing of an LED explosion-proof lamp includes a lamp housing 1, a fixing base 2, a connecting base 3 and a power base 4, wherein the fixing base 2 is fixedly connected to the top of the lamp housing 1, the connecting base 3 is connected to the top of the fixing base 2, the power base 4 is fixedly connected to the top of the connecting base 3, and also includes a connecting component, which is arranged on the top of the lamp housing 1.

[0023] like Figure 1-5 As shown, in order to quickly and stably connect the shell to the power socket 4 and avoid loosening of the connection, the connection assembly includes a fixing plate 5, a bidirectional screw 6, an adjustment plate 7 and a cross column 8. The bottom of the connecting seat 3 is fixedly connected with symmetrically distributed plug posts 9, and a slot 10 is provided on the top of the fixing seat 2. The plug posts 9 and the slot 10 are adapted. The fixing plate 5 is fixedly connected to the top of the lamp housing 1 and is symmetrically distributed. The bidirectional screw 6 penetrates the fixing plate 5 and is rotatably connected to the fixing plate 5. The adjustment plate 7 penetrates the bidirectional screw 6 and is threadedly connected to it. The adjustment plate 7 is symmetrically distributed, and the fixing plate 5 is fixedly connected to the opposite side walls. A guide rod 11 is connected, and the guide rod 11 passes through the adjustment plate 7 and is slidably connected thereto, the cross column 8 is fixedly connected to the outer wall of the adjustment plate 7, a through hole 12 is provided in the middle position of the plug column 9, the through hole 12 is adapted to the cross column 8, a transverse groove 13 is provided on the fixing seat 2, the transverse groove 13 is communicated with the slot 10, the cross column 8 is adapted to the transverse groove 13, a disc 14 is provided at both ends of the bidirectional screw 6, the disc 14 is provided with a circularly arranged positioning hole 15, the fixing plate 5 is provided with a circularly arranged positioning groove 16, the positioning groove 16 and the positioning hole 15 have the same inner diameter, and the positioning hole 15 is threadedly connected with a positioning column 17

[0024] In order to ensure the sealing effect at the connection between the shell and the power base 4, a sealing ring 18 is provided at the connection between the fixing base 2 and the connecting base 3.
