Under the linkage action of the push-pull bar 63, the installation shaft 1 64 and the installation shaft 2 69, the rotation of the rotating disk 62 can push and pull the brush plate 66 horizontally through the push-pull bar 63, so that the brush plate 66 is in a state of high-speed reciprocating horizontal movement, and the brush plate 66 is in a state of scrubbing the display screen 3. The continuous horizontal friction between the brush plate 66 and the display screen 3 can clean the impurities adhering to the display screen 3, effectively improve the cleaning effect of the brush plate 66 on the display screen 3, and ensure the cleaning quality.

[0032] like Figure 6 As shown, in this embodiment, a filter bag 76 is detachably installed at the dust outlet end of the dust outlet pipe 72, an external thread is provided at one end of the dust outlet pipe 72 close to the filter bag 76, an internal thread sleeve threadedly connected to the external thread is installed at the dust inlet end of the filter bag 76, and the filter bag 76 and the dust outlet pipe 72 are threadably connected, so that the dust inside the filter bag 76 can be cleaned conveniently.

At this time, when the linear motor 44 drives the brush plate 66 and the rubber scraper 67 to clean the uppermost display screen 3, the uppermost display screen 3 can be cleaned in all aspects to avoid cleaning the four corners. A lifting carrier plate 43 is fixedly connected between the movable ends of the three electric telescopic rods 42, and linear motors 44 are installed on both sides of the top of the lifting carrier plate 43. The brush plate 66 and the rubber scraper 67 driven by the linear motor 44 are vertically lifted to clean the display screen 3. Therefore, the display device can be fully cleaned without manual climbing operation, which reduces the intensity and difficulty of cleaning work.

[0040] When in use, multiple vertical frames 21 are installed on the storage cabinet 1 at equal intervals, and a crossbeam 24 is fixed between two adjacent vertical frames 21, a plurality of installation cavities 23 are formed by the crossbeam 24, and a display screen 3 is installed on the front side of the installation cavity 23; When installing the display screen 3, the vertical drive components 4 on both sides are correspondingly moved to the upper sides of the card seats 26 on both sides, and the display screen 3 is pushed into the installation cavity 23. When the back of the display screen 3 is in contact with the vertical frame 21 and blocked, the display screen 3 can no longer be pushed into the installation cavity 23. At this time, the display screen 3 is moved downward so that the display screen 3 is stuck in the card slot 25, and the installation of the display screen 3 is completed. The L-shaped undercut 31 is removed from the card slot 25 to complete the removal of the display screen 3. The process of installing the lifting plate 6 is as follows: Rotate the L-shaped plate 51 toward the lifting plate 6, so that the lifting plate 6 and the rotating frame 5 are in a vertical state, and then make the connecting block 55 enter the inner part of the connecting groove 54 for clamping, and then fix the L-shaped plate 51 and the connecting block 55 together with the fixing bolts 56 to complete the installation of the lifting plate 6. After removing the fixing bolts 56, the lifting plate 6 can be disassembled; The linear motor 44 drives the rotating frame 5 to move upward or downward, thereby driving the lifting plate 6 to move vertically. When the lifting plate 6 is lifted or lowered, the belt will also drive the brush plate 66 and the rubber scraper 67 to move vertically. The bristles of the brush plate 66 and the rubber scraper 67 will contact and clean the display end surface of the display screen 3. The linear motor 44 drives the brush plate 66 and the rubber scraper 67 to move vertically to clean the display screen 3. Furthermore, when the brush plate 66 and the rubber scraper 67 are used to clean the upper edge of the top display screen 3, the electric telescopic rod 42 is extended to move the linear motor 44 upward, so that the upper end of the linear motor 44 is higher than the height of the top display screen 3. At this time, when the linear motor 44 drives the brush plate 66 and the rubber scraper 67 to clean the top display screen 3, the top display screen 3 can be cleaned in all aspects. While cleaning the display end surface of the display screen 3, the motor drives the dust suction blades to generate negative pressure at high speed. The negative pressure suction force sucks the raised dust into the interior of the dust suction pipe 73 through the dust inlet hole 74, and enters the interior of the dust suction bin 71 through the connecting pipe 75, and finally enters the interior of the filter bag 76 through the dust outlet pipe 72 for storage.
