[0025] Among them; an installation plate 13 is provided inside the back plate 1. The installation plate 13 is provided with heat dissipation notches. The design of the heat dissipation notches on the installation plate 13 effectively increases the heat dissipation area and improves the heat dissipation performance of the device. This is particularly important for devices that need to run for a long time or generate high heat, and can prevent performance degradation or damage caused by overheating. A second connecting spring 20 is fixedly connected to the bottom of the installation plate 13, and one end of the second connecting spring 20 is fixedly connected to the inner wall of the back plate 1. A second telescopic rod 12 is fixedly connected to the bottom of the installation plate 13, and one end of the second telescopic rod 12 is fixedly connected to the inner bottom of the back plate 1. The second telescopic rod 12 passes through the inside of the second connecting spring 20. The setting of the second connecting spring 20 can absorb and relieve vibrations and impacts from all directions during the operation of the device, playing a role of stable buffering. This not only protects the precision components inside the device from damage, but also extends the service life of the device.

[0030] Among them; a first connecting frame 14 is fixedly installed at the bottom of the installation plate 13. A connecting arm rod 15 is rotatably connected to the first connecting frame 14. One end of the connecting arm rod 15 is rotatably connected to a second connecting frame 16, and the second connecting frame 16 is slidably connected to the inner bottom of the back plate 1.

[0031] Among them; a display frame 18 is provided above the back plate 1, and plug-in boards 19 are fixedly connected to both sides of the bottom of the display frame 18.

[0032] Working principle: When in use, when installing the display frame 18, first align the plug-in boards 19 on both sides of the display frame 18 with the gaps above the movable blocks 2, and then press the display frame 18 downward, so that the bottom of the plug-in board 19 squeezes the movable block 2 and pushes the extrusion block 3 connected thereto to move downward together. And during the downward movement of the extrusion block 3, the abutment against the abutting plate 4 will be gradually released, so that the abutting plate 4 and the clamping rubber strip 5 fixedly installed thereon move towards the plug-in board 19 under the elastic force of the telescopic spring 8 and fix the plug-in board 19 inside the back plate 1 to complete the preliminary fixation. Then, push the push rods 11 on both sides of the back plate 1 so that the end thereof squeezes one end of the rotating rod 10, and then the other end of the rotating rod 10 abuts against the abutting plate 4, thereby limiting the abutting plate 4. In this way, when rotating the push rod 11 to make the limiting block on the outer surface of the push rod 11 form a dislocation with the inner wall of the back plate 1, the installation of the display frame 18 is realized, and the connection of the display frame 18 can be conveniently released by repeating the above operations in reverse, which is convenient for later maintenance and replacement of the electrical components inside the back plate. At the same time, when the back plate 1 is impacted or dropped as a whole, the electronic devices installed on the mounting plate 13 will generate a downward pressure on the mounting plate 13 under the action of inertia, thereby pushing the mounting plate 13 to move towards the inner bottom of the back plate 1, so as to transfer the force received by the mounting plate 13 to the connecting spring two 20 below for slow release. And during the downward movement of the mounting plate 13, the connecting frame one 14, the connecting arm rod 15 and the connecting frame two 16 can effectively ensure the stability of the movement of the mounting plate 13.
