[0027] See also Figure 1-5 ,The utility model provides a technical solution:

[0028] A video intercom extension comprises a mounting plate 1, the side wall of the mounting plate 1 is fixedly provided with an adjustment component 2, the adjustment component 2 comprises two first fixed plates 201, the tops of the two first fixed plates 201 are rotatably connected with a lead screw 202, the outer wall of the lead screw 202 is threadedly connected with a slider 203, the side wall of the slider 203 is fixed with a hinge seat 204, the inner wall of the hinge seat 204 is hinged with an adjustment rod 205, the side walls of both sides of the mounting plate 1 are fixed with connecting rods 206, the other ends of the side walls of the two connecting rods 206 are rotatably connected with a pin 207, the side wall of the pin 207 is fixed with an intercom body 3, the other end of the adjustment rod 205 is fixedly connected to the back of the intercom body 3, a cleaning component 4 is fixedly provided on one side wall of the intercom body 3, a display screen 5 is embedded in the side wall of the intercom body 3, and a microphone 6 is fixedly provided on one side wall of the intercom body 3. In the present invention, the user rotates the lead screw 202 to drive the slider 203 to move, thereby adjusting the inclination angle of the adjustment rod 205 hinged to the hinge seat 204, and then adjusting the inclination angle of the intercom body 3. The position of the intercom body 3 is limited by the connecting rod 206, so that the video intercom extension can be adapted to users of different heights, and the display screen 5 can be directly facing the user's face, which is more convenient to use.

[0029] Specifically, the cleaning assembly 4 includes a second fixed plate 401, with a motor 402 fixed to its bottom. A reciprocating screw 403 is fixed to the output end of the motor 402. A movable plate 404 is threadedly connected to the outer wall of the reciprocating screw 403. A cleaning brush 405 is clamped to the inner wall of the movable plate 404. The motor 402 is electrically connected to an external power source. Turning on the motor 402 drives the reciprocating screw 403, which in turn drives the movable plate 404 to move up and down. This in turn causes the cleaning brush 405 to move up and down, cleaning dust accumulated on the surface of the microphone 6 after long-term use, thereby improving the reception quality of the video intercom extension.

[0030] In some embodiments, dust may accumulate on the cleaning brush 405 after long-term use, and the cleaning brush 405 can be easily disassembled for cleaning or replacement through a buckle.

[0031] Furthermore, a handle 208 is fixedly provided at the bottom of the lead screw 202, and a plurality of raised vertical edges are fixedly provided on the outer wall of the handle 208. The raised vertical edges on the surface of the handle 208 increase friction, making it easier for staff to use.

[0032] It is worth noting that the material of the mounting plate 1 is PVC, and a protective film is attached to the surface of the display screen 5. The PVC material is fireproof and heat-resistant, and has good use effect. The protective film prevents the surface of the display screen 5 from being damaged.

[0033] It is noteworthy that the height of the reciprocating screw 403 matches the height of the microphone 6, and the end of the cleaning brush 405 is in contact with the side wall of the microphone 6. By the cleaning brush 405 in contact with the side wall of the microphone 6, dust accumulated on the surface of the microphone 6 can be cleaned more fully.

[0034] In addition, the side wall of the mounting plate 1 is provided with a plurality of screw holes 7, and the inner walls of the circumferences of the plurality of screw holes 7 are all threadedly connected with bolts 8. The mounting plate 1 is fixed by screwing the bolts 8 into the screw holes 7, thereby fixing the video intercom extension.

[0035] In addition, the circuits, electronic components, and modules involved in this utility model are all prior art and can be fully implemented by those skilled in the art. Needless to say, the content protected by this utility model does not involve improvements to the internal structure and method.

[0036] The device or equipment models involved in this article are as follows:

[0037] The model of motor 402 may be: Y90S-2.

[0038] Working principle: When the device is needed to be used as a video intercom extension, the mounting plate 1 is fixed by screwing the bolt 8 into the screw hole 7, thereby fixing the video intercom extension. The user rotates the lead screw 202 to drive the slider 203 to move, thereby adjusting the tilt angle of the adjustment rod 205 hinged to the hinge seat 204, and then adjusting the tilt angle of the intercom body 3. The position of the intercom body 3 is limited by the connecting rod 206, so that the video intercom extension can be adapted to users of different heights, so that the display screen 5 is facing the user's face, making it more convenient to use. The cleaning brush 405 can be easily removed by the user through the buckle to clean or replace the cleaning brush 405. The raised vertical edges on the surface of the handle 208 increase the friction force, making it easier for the staff to use the cleaning brush 405. The protective film can prevent the surface of the display screen 5 from being damaged.
