[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0012] 1. By using the motor, the threaded rod and the threaded sleeve in combination, the longitudinal reciprocating motion of the cleaning roller can be realized, so that the cleaning and dust removal treatment of both sides of the entire display device can be carried out later, thereby preventing a large amount of dust and impurities from remaining on the surface of the display device, affecting the subsequent teaching effect and normal viewing.

[0022] When in use, the display screens 14 symmetrically arranged on both sides of the protective shell 1 can be used for teaching demonstrations, and when there are many stains on the surface of the display screen 14, the moving cleaning roller 11 can be used to clean the display screen 14, which is convenient and quick;

[0023] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a motor 3 is fixedly installed on one side of the top of the protective shell 1, and a threaded rod 4 is connected to the output end of the motor 3. The threaded rod 4 is threadedly connected to the threaded sleeve 5 through a threaded groove 6, and the threaded rod 4 is symmetrically distributed along the vertical center line of the protective shell 1. The outer surface of the threaded rod 4 is sleeved with a threaded sleeve 5, and a threaded groove 6 is opened on the inner side of the threaded sleeve 5. A connecting structure is fixedly connected to one side of the threaded sleeve 5. The connecting structure includes a connecting pipe 7, a movable rod 8 and a side plate 9. The connecting pipe 7 is fixedly installed on one side of the threaded sleeve 5, and a movable rod 8 is passed through the inner side of one end of the connecting pipe 7. The movable rod 8 is slidably connected to the connecting pipe 7, and the connecting pipe 7 is symmetrically distributed along the vertical center line of the threaded sleeve 5, and the movable rod 8 is away from the connecting pipe 7. A side plate 9 is fixedly mounted on one end of the connecting tube 7, a bearing seat 10 is fixedly mounted on the inner side of one end of the connecting structure, and a cleaning roller 11 is connected to the other end of the bearing seat 10, the cleaning roller 11 is rotatably connected to the side plate 9 through the bearing seat 10, and the cleaning rollers 11 are symmetrically distributed on both sides of the protective shell 1, an auxiliary slider 12 is fixedly mounted on one end of the movable rod 8, a return spring 13 is sleeved on the outer surface of the movable rod 8, a display screen 14 is fixedly mounted on one end of the protective shell 1, and the display screens 14 are equidistantly distributed on both sides of the protective shell 1, and a rubber corner protector 15 is fixedly mounted on one side of the bottom of the protective shell 1, and the rubber corner protector 15 is made of rubber, which can protect the bottom corner of the protective shell 1;

[0024] When the display screen 14 needs to be cleaned, the motor 3 is used to rotate the threaded rod 4 connected to its output end. Since the threaded rod 4 is threadedly connected to the threaded sleeve 5 through the thread groove 6, the threaded sleeve 5 can move longitudinally when the threaded rod 4 rotates, and then the threaded sleeve 5 drives the connecting pipe 7 to move longitudinally. Combined with the movement of the connecting pipe 7, the side plate 9 can be driven to move longitudinally through the movable rod 8. Since the cleaning roller 11 is rotatably connected to the side plate 9 through the bearing seat 10, when the side plate 9 moves longitudinally, the cleaning roller 11 will move longitudinally along the surface of the display screen 14, and the cleaning roller 11 will also move longitudinally. The movable rod 8 is slidably connected to the connecting tube 7 through the auxiliary slider 12, so when the reverse force generated by the deformation of the reset spring 13 drives the auxiliary slider 12 to slide on the inner side of the connecting tube 7, the movable rod 8 will pull the side plate 9, and then the side plate 9 will pull the cleaning roller 11, so that the cleaning rollers 11 on both sides can better fit the surface of the display screen 14, which is convenient for the subsequent better cleaning of the surface of the display screen 14, and the overall practicality is higher;

[0025] Specific working principle:

[0026] The display screens 14 symmetrically arranged on both sides of the protective shell 1 can be used for teaching demonstration processing. When the surface of the display screen 14 is attached with a lot of stains and needs to be cleaned, the motor 3 is used to rotate the threaded rod 4 connected to its output end. Since the threaded rod 4 is threadedly connected with the threaded sleeve 5 through the threaded groove 6, the longitudinal movement of the threaded sleeve 5 can be realized when the threaded rod 4 rotates, and then the threaded sleeve 5 drives the connecting pipe 7 to move longitudinally. Combined with the movement of the connecting pipe 7, the side plate 9 can be driven to move longitudinally through the movable rod 8. Since the cleaning roller 11 is rotatably connected with the side plate 9 through the bearing seat 10, when the side plate 9 moves longitudinally, the cleaning roller 11 will move along the display screen 14. The surface moves longitudinally, and the cleaning roller 11 also rotates accordingly, and then the rotating cleaning roller 11 is used to clean the surface of the display screen 14, so as to facilitate better removal of stains on the surface of the display screen 14 in the future, and ensure better subsequent teaching treatment. Since the movable rod 8 is slidably connected to the connecting tube 7 through the auxiliary slider 12, when the reverse force generated by the deformation of the reset spring 13 drives the auxiliary slider 12 to slide on the inner side of the connecting tube 7, the movable rod 8 will pull the side plate 9, and the rear side plate 9 will pull the cleaning roller 11, so that the cleaning rollers 11 on both sides can better fit the surface of the display screen 14, so as to facilitate better subsequent cleaning of the surface of the display screen 14, and the overall practicality is higher.
