The first protrusion 122 and the first mating post 214 correspond one-to-one. The first positioning hole 123 and the first fixing hole 215 are aligned with each other. The first connector 30 passes through the first positioning hole 123 and is threaded into the hole wall of the first fixing hole 215. Then, the first box body 11 is installed back onto the second box body 12.
[0036] When the lamp body 20 is engaged with the power box 10 in the horizontal direction, the first box body 11 is removed from the power box 10, and the second box body 12 is rotated on the bracket 14 so that the decorative surface 111 faces down and the mating surface 121 faces up. Then, the mating surface 213 of the lamp box 21 faces up, and the side of the second mating post 216 is attached to the second protrusion 124 of the second box body 12 in the horizontal direction. The second protrusion 124 and the second mating post 216 correspond one-to-one. The second positioning hole 125 and the second fixing hole 217 are aligned with each other. The second connector 40 passes through the second positioning hole 125 and is threaded into the hole wall of the first fixing hole 215. Then, the first box body 11 is installed back onto the second box body 12. In addition, this utility model also includes several pull rings 50. The bottom of the pull ring 50 can be installed on the first docking post 214 or removed from the first docking post 214 through the direction of the threaded connection. The pull ring 50 can help to lift the lamp body 20 to reduce the load on the power box 10, and at the same time prevent the power box 10 from tilting to one side when it is hung up.
[0037] The beneficial effects of this fixed-angle switchable explosion-proof lamp are as follows: By setting a first protrusion 122 and a second protrusion 124 on the power box 10, and setting a first docking post 214 and a second docking post 216 on the lamp body 20, the lamp body 20 can cooperate with the power box 10 in either a vertical or planar direction. When the lamp body 20 cooperates with the power box 10 in a vertical direction, the power box 10 is positioned above the lamp body 20, and the first connecting member 30 passes through the first protrusion 122 and is installed on the first docking post 214. When the lamp body 20 cooperates with the power box 10 in a horizontal direction, the lamp body 20 is positioned on one side of the power box 10, and the second connecting member 40 passes through the second protrusion 124 and is installed on the second docking post 216. This utility model has a flexible structure and can be assembled according to customer needs. During use, customers can also change the layout of the lamp body 20 on the power box 10 according to their own usage needs and installation environment, making it highly practical.
