At the same time, the protective plate 602 can be flipped, so as to facilitate the use of the intercom equipment body 4, further improving the practicality of the device.

[0023] It should be noted that the intercom device body 4 is a mature and public technology in the prior art, so its specific structure and working principle will not be described in detail in this article.

[0024] See also Figure 3The mounting mechanism includes a disassembly rod 501 slidably connected to the bottom surface of the mounting plate 1, a rectangular groove 502 is provided in the mounting plate 1, and a movable hole is provided on the bottom surface of the mounting plate 1 that is connected to the rectangular groove 502 and is used for the disassembly rod 501 to pass through. The rectangular groove 502 is arranged at the bottom of the mounting groove 2, and two guide rods 503 are fixed between the upper and lower inner walls of the rectangular groove 502. A connecting plate 504 fixed to the bottom surface and the top of the disassembly rod 501 is slidably connected between the two guide rods 503, and a spring 505 is sleeved on the outer peripheral wall of the guide rod 503. The rectangular groove 502 is used for the connecting plate 504 to slide up and down inside it, and two guide holes are provided on the top surface of the connecting plate 504 for the guide rod 503 to pass through. The spring 505 is arranged at the bottom of the connecting plate 504. When the intercom device body 4 needs to be disassembled for repair, the disassembly rod 501 is pulled downward, and the disassembly rod 501 drives the connecting plate 504 to slide up and down. The plate 504 slides downward along the guide rod 503 inside the rectangular groove 502 and compresses the spring 505. A plurality of limit rods 506 are fixed to the top surface of the connecting plate 504, and a plurality of limit grooves 507 for the limit rods 506 to be inserted into the bottom surface of the mounting block 3. A plurality of jacks connecting the rectangular groove 502 and the mounting groove 2 and for the limit rods 506 to pass through are provided in the mounting plate 1. The limit rods 506 and the limit grooves 507 are clearance-matched. Further, the connecting plate 504 drives the plurality of limit rods 506 to slide downward, disengage from the limit grooves 507 and be stored in the rectangular groove 502. At this time, the intercom device body 4 can be horizontally slid so that the mounting block 3 on the back thereof slides out of the mounting groove 2 to complete the disassembly. After the inspection is completed, the above operation is reversed, and the connecting plate 504 is pushed upward and reset by the spring 505, so that the limit rods 506 are inserted into the limit groove 507 for limit fixing.

[0025] A spherical gripper is fixed to the bottom end of the disassembly rod 501. The spherical gripper facilitates grabbing the disassembly rod 501 and driving it to move downward, thereby facilitating the installation and disassembly operations of the intercom device body 4 and improving the maintenance and inspection efficiency of the intercom device body 4.

[0026] See also Figure 1 to Figure 2In this embodiment, the protective mechanism includes two support blocks 601 fixed on the front side of the mounting plate 1, and a protective plate 602 is rotatably connected between the two support blocks 601. A first magnetic block 603 is fixed to the top surface of the protective plate 602, and a first iron sheet 604 is fixed to the front side of the mounting plate 1. When the intercom device body 4 needs to be used, the bottom of the protective plate 602 is flipped upward so that the top surface is flipped to the back side to fit the mounting plate 1. At this time, the first magnetic block 603 and the first iron sheet 604 are attracted, and the protective plate 602 is located above the intercom device body 4, which is convenient for operating the intercom device body 4. Two second magnetic blocks 605 are fixed to the back side of the protective plate 602, and two second iron sheets 606 are fixed to the front side of the mounting plate 1. After using the intercom device body 4, the protective plate 602 is flipped back so that the second magnetic block 605 and the second iron sheet 606 are attracted. At this time, the protective plate 602 is flipped to the front side of the intercom device body 4 for protection.

[0027] The protective plate 602 is a U-shaped plate. The top surface and the back surface of the protective plate 602 are provided with grooves for installing the first magnetic block 603 and the second magnetic block 605. A rounded corner is provided on the back surface of the protective plate 602 near the top. It should be understood that the center of the rounded corner should be located on the rotation axis of the protective plate 602. Such a structure makes it easy for the flipped protective plate 602 to fit with the front side of the mounting plate 1.

[0028] The working principle of the above embodiment is:

[0029] (1) When the intercom device body 4 needs to be disassembled for repair, the disassembly rod 501 is pulled downward, and the disassembly rod 501 drives the connecting plate 504 to slide downward along the guide rod 503 inside the rectangular groove 502 and compress the spring 505. Further, the connecting plate 504 drives the plurality of limit rods 506 to slide downward and disengage from the limit groove 507 and be stored inside the rectangular groove 502. At this time, the intercom device body 4 can be horizontally slid so that the mounting block 3 on the back thereof slides out of the mounting groove 2 to complete the disassembly. After the inspection is completed, the above operation is reversed, and the connecting plate 504 is pushed upward and reset by the spring 505, so that the limit rod 506 is inserted into the limit groove 507 for limit fixing;

[0030] (2) When the intercom device body 4 needs to be used, the bottom of the protective plate 602 is flipped upward so that the top surface is flipped to the back side to fit with the mounting plate 1. At this time, the first magnetic block 603 is attracted to the first iron sheet 604, and the protective plate 602 is located above the intercom device body 4, which is convenient for operating the intercom device body 4. After using the intercom device body 4, the protective plate 602 is flipped in the opposite direction so that the second magnetic block 605 is attracted to the second iron sheet 606. At this time, the protective plate 602 is flipped to the front side of the intercom device body 4 for protection.
