Specific embodiments

[0029] The principles and features of the present utility model will be described below in conjunction with all the drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0030] The embodiment of the present utility model discloses an adjustable explosion - proof lamp bent arm.

[0031] Referring to Figures 1-9 , an adjustable explosion - proof lamp bent arm includes a first bent arm 1 and a second bent arm 2. The first bent arm 1 is connected to the lamp 3. One end of the first bent arm 1 away from the lamp 3 is rotatably connected to the second bent arm 2. The second bent arm 2 is connected to a lamp post 10. The lamp post 10 is generally fixed in a place where lighting is required, such as a chemical plant.

[0032] The first bent arm 1 includes a first fixing portion 12 and a first connecting portion 11. The first fixing portion 12 and the first connecting portion 11 are fixedly connected.
