[0006] Preferably, a pair of the protrusion side wall surfaces are each provided with an insertion hole, and the pair of the insertion holes cooperate with the pair of the insertion rods.

[0007] Preferably, each of the pair of slots has an inclined angle.

[0008] Preferably, a slide rod is movably inserted in the protection box, the lower end of the slide rod is connected to the connecting plate, and a button is provided at the upper end of the slide rod.

[0009] Preferably, a display and a control panel are provided on the side wall of the video intercom.

[0010] Beneficial Effects

[0011] The utility model provides a portable explosion-proof elevator intercom. The utility model is designed with a structure that can be easily disassembled. The device is fixed on the wall of the elevator. When a pair of doors are opened, the intercom can be used. If the situation is urgent, such as someone fainting, video communication with the outside world is required. It is best to disassemble the intercom to facilitate understanding of the specific situation inside the elevator. Pressing the button drives the protrusion to come out of the groove, and the video intercom can be used for portable movement. The device can increase the convenience of the video intercom, facilitate a more comprehensive understanding of the situation in the elevator through video, increase the fluency of communication, and greatly improve the success rate of rescue if it is necessary to rescue the people in the elevator.
