[0048] The heat dissipation mechanism 3 includes a heat dissipation fan 31, a U-shaped movable seat 32 is slidably provided inside the equipment box 1, one side of the U-shaped movable seat 32 is fixedly connected to one side of the heat dissipation fan 31, a through groove 35 is opened on one side of the equipment box 1, a reciprocating screw 36 is rotatably installed on the inner wall of the through groove 35, a driving rod 37 is fixedly installed on the side of the U-shaped movable seat 32 away from the heat dissipation fan 31, and a driving block 38 is rotatably installed on the end of the driving rod 37 away from the U-shaped movable seat 32, and the driving block 38 is in active contact with the threaded groove of the reciprocating screw 36.

[0049] By adopting the above technical solution, the reciprocating screw 36 is rotated, and the driving block 38 reciprocates along the two threaded grooves on the surface of the reciprocating screw 36. The driving block 38 causes the U-shaped moving seat 32 to reciprocate horizontally through the driving rod 37.

One end of the threaded rod 58 is rotatably connected to the outer wall of the arc-surface pressure plate 51, and the other ends of the two threaded rods 58 are fixedly installed with toggle plates 59.

[0057] By adopting the above technical solution, by setting the arc pressure plate 51 and the slot 53, when the signal line group of the audio and video switch 2 passes through the slot 53, by turning the dial 59, the dial 59 rotates the threaded rod 58, and the threaded rod 58 drives the arc pressure plate 51 to descend vertically, and the arc pressure plate 51 presses the signal line group, thereby fixing the signal line group.

[0058] The inner walls of the two arc pressure plates 51 are fixedly installed with first foam pads 52, the bottom walls of the two through-slots 53 are fixedly installed with second foam pads 54, the side walls of the two through-slots 53 are provided with two second guide grooves 55, the inner walls of the second guide grooves 55 are slidably connected with second guide blocks 56, and the opposite sides of two adjacent second guide blocks 56 are fixedly connected to a arc pressure plate 51.

[0059] By adopting the above technical solution, by setting the first foam pad 52 and the second foam pad 54, the signal line group passing through the through-slot 53 is located between the first foam pad 52 and the second foam pad 54. When the arc pressure plate 51 descends vertically, the first foam pad 52 descends synchronously, and the arc pressure plate 51 presses the signal line group through the first foam pad 52 to prevent the surface of the signal line group from being worn.

[0060] The present invention also provides a method for an audio and video signal exchange processing system, comprising the following steps:

[0061] S1. Multiple sound sources and multiple video sources are connected through the input system 200. At the same time, the output system 300 outputs stereo sound and high-definition video in 4 and 8 channels, and each channel does not interfere with each other.

[0062] S2, the power on / off system 400 is connected to the power supply, and executes the delayed power off command when not working, so that the whole device is powered off;

[0063] S3, the control system 500 executes the remote control switch command to realize the management and switching of the sound source and the video source, and at the same time connects to an external smart device to realize resource sharing, so as to facilitate the management and switching of the sound source and the video source to be controlled by the external smart device.

[0064] Working principle: through the audio and video processing system 100 composed of the input system 200, the output system 300, the power on and off system 400 and the control system 500, the input system 200 provides multiple sound source access ports and multiple video source access ports, the output system 300 outputs stereo and high-definition video, which is divided into 4-channel output and 8-channel output, and each channel does not interfere with each other, the power on and off system 400 is connected to the power supply required for audio and video input and output, and executes the delayed power off command when not working, the control system 500 can execute the remote control switch command to realize the management and switching of the sound source and video source, and can be connected to an external intelligent device to realize resource sharing, and at the same time, it is convenient to control the management and switching of the sound source and video source through an external intelligent device;

[0065] After the signal lines of the audio and video switch 2 are plugged into the respective module interfaces at the rear end of the audio and video switch 2, the staff makes the signal line groups pass through the two insertion slots 53 respectively, and the signal line groups contact the upper surfaces of the two second foam pads 54, and then manually toggle the two toggle disks 59 respectively, and the two toggle disks 59 rotate the two threaded rods 58, and the two threaded rods 58 rotate while driving the two arc-surface pressure plates 51 and the two first foam pads 52 to descend vertically, and the two arc-surface pressure plates 51 press the signal line groups on the two second foam pads 54 through the two first foam pads 52, thereby conveniently realizing the fixation of the signal line group, improving the stability of the signal line group of the audio and video switch 2, and at the same time, avoiding the signal line group from falling off due to external pulling;

[0066] When the audio and video switch 2 is running, the staff starts the drive motor 39 and the cooling fan 31 at the same time, and the cooling fan 31 generates airflow. At the same time, the drive shaft of the drive motor 39 rotates the reciprocating screw 36. When the reciprocating screw 36 rotates, the drive block 38 moves back and forth along the two threaded grooves of the reciprocating screw 36. The drive block 38 causes the U-shaped moving seat 32 to move back and forth horizontally through the drive rod 37, and the U-shaped moving seat 32 causes the cooling fan 31 to move back and forth horizontally synchronously. As the cooling fan 31 moves back and forth horizontally, the airflow generated by the cooling fan 31 contacts the various modules at the rear end of the audio and video switch 2, so that the various modules at the rear end of the audio and video switch 2 are cooled. At the same time, the high-temperature airflow generated by the audio and video switch 2 is discharged through the heat dissipation slot 12, the second ventilation slot 14 and the first ventilation slot 15, thereby conveniently realizing the heat dissipation and cooling of the audio and video switch 2, thereby effectively improving the operation efficiency of the audio and video switch 2.
