Principle of operation

When the multifunctional display bracket starts to be started from a static state, the arc-shaped push block 27 is rotated to be clamped at the clamping bayonet 55, the arc-shaped push block 27 pushes the clamping push rod 13 to drive the clamping arm 16 to move, and the clamping head 15 moves to a position farthest away from the bracket disc 12. The bottom edge of the display is placed at the bottom support 19 and gradually attached to the support disc 12, the back of the display is contacted with and pushes the clamping rotating shaft 25 to move towards the direction of a clamping rotating shaft tailstock 56, the arc-shaped push block 27 is separated from the clamping bayonet 55, the coil spring 24 drives the clamping rotating shaft 25 to reset through the coil spring shaft sleeve 26, the arc-shaped push block 27 resets and is separated from the contact with the clamping push rod 13, the clamping arm 16 drives the clamping head 15 to move towards the direction of the clamping rotating shaft 25 under the action of the clamping spring 14 and clamps and fix the display, and the buffer design of the clamping arm 16 enables the clamping head 15 to slowly move and contact the side wall of the display, so that the display is prevented from being damaged.

When the display during operation, the thermovent hot-air gets into inside dustproof heat dissipation case 10, heat sensor 33 detects and starts heat dissipation motor 29 when the temperature reachs the setting value, heat dissipation motor 29 gets rid of the inside hot-air of dustproof heat dissipation case 10 through going out aerofoil 30 department, it has the one-way function of giving vent to anger to go out aerofoil 30, prevent that outside air from going into from going out aerofoil 30 department, outside air will be got into inside dustproof heat dissipation case 10 and the display by dustproof membrane 11 department through dust removal filtration back, effectively prevent that the dust from getting into the display.

When the display screen is turned off, the dust electromagnetic block 53 is started to drive the dust detector 52 to move, the dust detector 52 detects the light reflection intensity of the display surface, and if the reflection intensity is lower than an expected set value, it is determined that the display surface has more dust and impurities. At this time, the wiping box motor 23 is started to drive the screen wiping box 20 to rotate to the position of the screen surface of the display through the bent rod 45, and the wiping cloth 42 is attached to the screen surface. Cleaning solution electromagnetism piece 48 starts to drive cleaning solution valve head 51 downstream through clamp plate 49, cleaning solution push pedal 43 switches on with cleaning solution ball 46 department, cleaning solution flows to wiping cloth 42 department and is absorbed, cleaning solution electromagnetism piece 48 resets and drives cleaning solution valve head 51 and resets, the cleaning solution stops to extrude, jacking motor 36 starts to drive jacking gear 37 and rotates, jacking gear 37 drives jacking screw rod 35 through jacking nut 38 and removes, jacking screw rod 35 promotes jacking piston 39 and removes towards flexible jacking rod 40 direction, flexible jacking rod 40 expandes and drives and remove wiping plate 34 rebound, it wipes the cleanness to remove wiping cloth 42 and wipe the display screen to remove wiping plate 34. After cleaning, the jacking piston 39 is driven to reset by the reverse rotation of the jacking motor 36, the movable wiping plate 34 is driven to move downwards to reset by the reset of the telescopic jacking rod 40, and the screen wiping box 20 is driven to reset by the reverse rotation of the wiping box motor 23.
