Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 6 The present invention provides a technical solution: a display screen structure for exhibition with a cleaning and storage function, comprising a storage booth 1, a display screen 2 and a storage and display structure 3 for storing and displaying the display screen 2, the storage booth 1 is a rectangular structure with an opening on one side and a hollow interior, the storage and display structure 3 is installed inside the storage booth 1, the storage and display structure 3 comprises a driving component 31, a display component 32, a cleaning component 33 and a vibrating component 36 for vibrating dust on the cleaning component 33, the display component 32 is connected to the driving component 31 through an angle adjustment member, the cleaning component 33 is connected to the driving component 31 through a linkage member, the driving component 31 comprises a driving motor 311, the output end of the driving motor 311 is connected to a driving screw 312 through a coupling, the driving screw 312 is connected to a first bearing seat 313 at one end away from the driving motor 311, a sliding block 314 is slidably connected to the driving screw 312, and guides are arranged parallel to both sides of the driving screw 312 The sliding rod 315, one end of the two guide sliding rods 315 is connected to the outer wall of the driving motor 311, the sliding block 314 is provided with a sliding block 3141 near the bottom of the outer wall on both sides, and the two sliding blocks 3141 are respectively connected with the guide sliding rod 315 close to them by sliding engagement, and a protective frame 317 is provided just above the driving screw rod 312, and the protective frame 317 is arranged in a U-shaped structure, and the top of the protective frame 317 is connected to the top of the storage booth 1, and the top of the protective frame 317 is connected to the storage booth 1. The inner wall of the top of the storage slot of the exhibition stand 1 is fixed to ensure a stable connection. The protection frame 317 is connected to the top of the driving motor 311 near the middle bottom. When the driving motor 311 is working, the driving motor 311 drives the driving screw 312 to rotate, and the sliding block 314 slides on the driving screw 312. The sliding block 314 is guided and slid on the guide slide bar 315 through the sliding block 3141. The guide slide bar 315 ensures that the sliding block 314 always moves in a horizontal position.

[0033] The display assembly 32 includes a display rack 321, which is symmetrically arranged at the bottom of the guide slide bar 315. The display rack 321 is L-shaped. The top of one end of each display rack 321 is connected to the outer wall of the drive motor 311 through a column. The two display racks 321 are provided with a guide groove 3211. The angle adjustment member includes a vertical rod 341, a guide connecting rod 342 and a fixed rod 343. The vertical rod 341 is installed at the bottom of the two sliding blocks 3141. The bottom of the two vertical rods 341 The outer walls are slidably connected to the guide grooves 3211 through the connecting crossbar 3411, the fixing rod 343 penetrates and connects and is located inside the two guide grooves 3211, one end of the guide connecting rod 342 is rotatably connected to the connecting crossbar 3411, and the other end of the guide connecting rod 342 is rotatably connected to the fixing rod 343, the back of the display screen 2 is provided with a mounting groove 21, and the inner walls on both sides of the mounting groove 21 are provided with C-shaped snap seats 22, and the display screen 2 is snapped on the fixing rod 343 between the two display frames 321 through the snap seats 22;

[0034] It should be noted that, in this embodiment, the fixed rod 343 connected to the display screen 2 is connected to the connecting cross bar 3411 at the bottom of the vertical rod 341 through the guide link 342, and the guide link 342 is rotatably connected to the fixed rod 343 and the connecting cross bar 3411 respectively. Since the guide groove 3211 is an L-shaped structure, the connecting cross bar 3411 drives the fixed rod 343 to move through the guide link 342 when the guide groove 3211 located in the horizontal position moves. When the fixed rod 343 reaches the turning structure of the guide groove 3211, the fixed rod 343 performs an angle adjustment movement. Figure 3 and Figure 4 At this time, the guide link 342 is synchronously adjusted in angle, and the display screen 2 is further adjusted in angle for display. The angle adjustment does not require external electric drive, which saves costs.

[0035] When the driving motor 311 drives the driving screw 312 to rotate, the sliding block 314 slides on the driving screw 312, and the sliding block 3141 connected to the sliding block 314 is connected to the connecting cross bar 3411 through the vertical rod 341. When the connecting cross bar 3411 moves in the guide groove 3211 located in a horizontal position, it drives the fixed rod 343 to move through the guide connecting rod 342 to realize the exhibition and storage of the display screen 2. When the fixed rod 343 reaches the turning structure of the guide groove 3211, the angle of the display screen 2 can be adjusted, and the angle adjustment is convenient.

[0036] See also Figure 1 , 25, the cleaning component 33 includes a cleaning roller 331, on which an electrostatic dust removal cloth is pasted. When the display screen 2 passes through the electrostatic dust removal cloth, the static electricity on the surface of the electrostatic dust removal cloth will generate an electrostatic adsorption force with the dust particles. Since the dust particles have opposite charges, they will be firmly adsorbed by the electrostatic dust removal cloth. The electrostatic dust removal cloth itself is soft and particle-free. It will not leave fiber residues or scratch the screen like an ordinary rag, thereby ensuring the subsequent display effect of the display screen 2. Bearing supports 332 are symmetrically arranged on the cleaning roller 331. The outer walls of the two bearing supports 332 are connected to the end of the guide slide bar 315 away from the end of the driving motor 311 through a fixing plate 333. A through groove 3331 is opened on one of the fixing plates 333. A support 3332 is installed inside the through groove 3331. The support 3332 is arranged in an inverted T-shaped structure. The linkage parts include a linkage rod 35, a driving gear 351 and The driven gear 352 and the driving gear 351 are connected to one end of the linkage rod 35, and the end of the linkage rod 35 away from the driving gear 351 is connected to the end of the driving screw 312 inside the first bearing seat 313, and the driven gear 352 is meshed and connected with the driving gear 351, and the driven gear 352 is fixedly sleeved on the outer circumferential wall of the cleaning roller 331. The rapping assembly 36 includes a sleeve 361, a rapping swing rod 362 and a rapping ball 363. The rapping swing rod 362 is arranged in an L-shaped structure, and the sleeve 361 is fixedly sleeved on the outer wall of the linkage rod 35. A swing groove 3611 is provided on the outer circumferential wall of the sleeve 361. The rapping swing rod 362 passes through the through groove 3331 and is rotatably connected to the support 3332 inside it. One end of the rapping swing rod 362 slides inside the swing groove 3611, and the other end of the rapping swing rod 362 movably abuts against the outer wall of the cleaning roller 331 through the rapping ball 363.

[0037] It should be noted that, in this embodiment, the cleaning roller 331 is connected to the driving screw 312 through a linkage member. When the driving screw 312 is working, the cleaning roller 331 is further driven to rotate, and the dust on the display screen 2 is adsorbed and cleaned by the electrostatic dust removal cloth. A single motor performs multiple kinetic energy linkage driving modes, which saves costs.

[0038] When the driving screw 312 rotates, the linkage rod 35 connected thereto is further driven to rotate. At this time, the driving gear 351 at the other end of the linkage rod 35 is meshed and connected with the driven gear 352 on the cleaning roller 331, driving the cleaning roller 331 to rotate.

[0039] It should be noted that the sleeve 361 is sleeved on the linkage rod 35, and the rapping swing rod 362 slides inside the swing groove 3611 on the sleeve 361 at one end away from the rapping ball 363. When the sleeve 361 rotates, the rapping swing rod 362 follows the structure of the swing groove 3611 to move and swing, and the rapping ball 363 follows the back and forth swing of the rapping swing rod 362 to vibrate the cleaning roller 331, and the dust on the cleaning roller 331 is knocked off by the vibration, thereby ensuring the subsequent use of the cleaning roller 331.

[0040] When display is required, the driving motor 311 is controlled by an external controller to work, the driving motor 311 drives the driving screw 312 to rotate, the sliding block 314 slides on the driving screw 312, the sliding block 314 slides on the guide slide bar 315 through the sliding card block 3141, the sliding card block 3141 connected to the sliding block 314 is connected to the connecting cross bar 3411 through the vertical rod 341, and the connecting cross bar 3411 drives the fixing rod 343 to move through the guide connecting rod 342 when the guide groove 3211 located in the horizontal position moves, so that the display screen 2 is extended and stored inside the storage booth 1. When the fixing rod 343 reaches the guide groove 3211, the fixing rod 343 is moved. When the turning structure of 11 is at the turning structure, the angle of the display screen 2 can be adjusted. At the same time, since the driving screw rod 312 further drives the cleaning roller 331 to rotate when working, the dust on the display screen 2 is adsorbed and cleaned by the electrostatic dust removal cloth. Since the shaft sleeve 361 is sleeved on the linkage rod 35, when the shaft sleeve 361 rotates, the end of the rapping swing rod 362 away from the rapping ball 363 slides inside the rapping groove 3611 on the shaft sleeve 361. At this time, the rapping swing rod 362 follows the structure of the rapping groove 3611 to move and swing, and the rapping ball 363 follows the back and forth swing of the rapping swing rod 362 to vibrate the cleaning roller 331, thereby ensuring the subsequent use of the cleaning roller 331.

[0041] The specific operation is as follows: when storing, the driving motor 311 is started through the external controller, the driving motor 311 drives the driving screw 312 to rotate, the sliding block 314 slides on the driving screw 312, and moves along the guide slide bar 315 through the sliding block 3141, the sliding block 314 drives the connecting cross bar 3411 to slide in the guide groove 3211 through the vertical rod 341, and the connecting cross bar 3411 drives the fixing rod 343 to move through the guide connecting rod 342, so that the display screen 2 is gradually stored in the storage booth 1;

[0042] During display, the driving motor 311 rotates in the reverse direction, the driving screw 312 drives the sliding block 314 to slide in the reverse direction, and the fixing rod 343 extends the display screen 2 from the inside of the storage stand 1 through the linkage of the guide link 342 and the connecting cross bar 3411. When the fixing rod 343 reaches the turning structure of the guide groove 3211, the angle of the display screen 2 is automatically adjusted through the guide link 342 to reach an angle suitable for display.

[0043] During cleaning, when the display screen 2 is extended or put into the storage booth 1, the surface of the display screen 2 will pass through the cleaning roller 331. The surface of the cleaning roller 331 is pasted with an electrostatic dust removal cloth, and its electrostatic adsorption force will adsorb dust on the surface of the display screen 2. The driving screw 312 drives the active gear 351 to rotate through the linkage rod 35, and the active gear 351 is meshed with the driven gear 352, thereby driving the cleaning roller 331 to rotate, so that the electrostatic dust removal cloth is in full contact with the surface of the display screen 2 to complete the cleaning. When the display screen 2 is stored in the storage booth 1, the cleaning roller 331 continues to rotate following the driving screw 312, and the shaft sleeve 361 also rotates with the linkage rod 35. One end of the vibration swing rod 362 slides in the swing groove 3611 of the shaft sleeve 361 and swings back and forth following the structure of the swing groove 3611. The vibration ball 363 vibrates the surface of the cleaning roller 331 as the vibration swing rod 362 swings, and the dust adsorbed on the electrostatic dust removal cloth is knocked off, thereby maintaining the subsequent cleaning effect of the cleaning roller 331.
