At this time, the mounting rod 5 and the long groove 6 are connected by friction. After the installation is completed, the extrusion component inside the long groove 6 is against the inside of the mounting rod 5, so that the friction between the mounting rod 5 and the long groove 6 is greater, thereby ensuring the stable installation of the explosion-proof back plate 2 and the explosion-proof frame 3. No external tools are required in this process, and the operation is simple and convenient.

[0022] The extrusion assembly includes an extrusion rod 7, both sides of which are arranged as inclined surfaces, a groove 8 is provided inside the long slot 6, the extrusion rod 7 is installed inside the groove 8, a plurality of extrusion springs 9 are fixedly installed inside the groove 8, one end of the extrusion spring 9 is fixed on the surface of the extrusion rod 7, the extrusion rod 7 is pressed against the surface of the mounting rod 5, when the mounting rod 5 is stuck in the long slot 6, it will first press against the inside of the extrusion rod 7, there is no need to press the extrusion rod 7, the extrusion rod 7 can be completely inserted into the groove 8 by relying on the extrusion force, after the installation is completed, the resilience of the extrusion spring 9 will make the extrusion rod 7 tightly press against the surface of the mounting rod 5.

[0023] A friction layer 10 is provided on the front of the extrusion rod 7, and the friction layer 10 increases the friction force on the surface of the extrusion rod 7. A magnetic attraction layer 11 is provided on the back of the extrusion rod 7, and the magnetic attraction layer 11 provides magnetic attraction force for the extrusion rod 7. A mounting groove 12 is provided on the back of the explosion-proof back plate 2, and an electromagnetic block 13 is installed inside the mounting groove 12.

At this time, it is very difficult to install the explosion-proof frame 3. At this time, the electromagnetic block 13 is energized, and the surface of the electromagnetic block 13 will have a large magnetic attraction force. At this time, the magnetic attraction layer 11 can be used to make the extrusion rod 7 stay away from the mounting rod 5, and the extrusion spring 9 is in a compressed state. At this time, it is also convenient to install the mounting rod 5, and then the electromagnetic block 13 can be powered off.

[0026] The cross bar 14 and the explosion-proof back plate 2 are integrally formed structures, and the cross bar 14 and the mounting rod 5 and the explosion-proof frame 3 are integrally formed structures, all of which are cast by aluminum alloy metal to ensure the tightness of the connection, thereby indirectly ensuring the explosion-proof function.

[0027] It should be noted that the utility model is an explosion-proof monitoring display. When in use, the electromagnetic block 13 is energized, and the surface of the electromagnetic block 13 will have a large magnetic attraction.
