[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1-5 As shown, the utility model provides a technical solution: a rental LED display screen with a dust removal function, comprising a frame 1, a main dust removal brush 6 and an auxiliary dust removal brush 8, storage grooves 11 are provided on both sides of the frame 1, a baffle 12 is provided at the front end of the storage groove 11, and a mounting hole 13 is provided on the back of the frame 1, LED modules 2 are installed between the storage grooves 11, and electric push rods 3 are provided at the rear ends of the inner walls of the storage grooves 11, the front ends of the piston rods of the electric push rods 3 are fixedly connected to the dust removal frame 4, the front ends of the dust removal frame 4 are rotatably connected to the dust removal rod 5, the inner surface of the dust removal rod 5 is bonded to the main dust removal brush 6, the top of the dust removal rod 5 is slidably connected to the extension rod 7, the inner surface of the extension rod 7 is bonded to the auxiliary dust removal brush 8, and a positioning frame 9 is provided on the back of the mounting hole 13.

[0027] Furthermore, the distance that the baffle 12 extends forward matches the thickness of the dust removal frame 4, and the distance from the end of the baffle 12 away from the storage groove 11 to the rotation center of the dust removal frame 4 matches the distance from the farthest extension point of the extension rod 7 to the rotation center of the dust removal frame 4. Through the setting of the baffle 12, the extension rod 7 can be squeezed during the rotation of the dust removal rod 5 to shrink it inside the dust removal frame 4.

[0028] Furthermore, two groups of electric push rods 3 are provided, two in each group, and the electric push rods 3 are symmetrically arranged about the central axis of the dust removal frame 4. The symmetrical arrangement can ensure the smoothness of the movement of the dust removal frame 4 and avoid increasing the friction between the dust removal rod 5 and the storage groove 11, which may cause the dust removal rod 5 to break.

[0029] Furthermore, a mounting cross plate 41 is provided on the back of the dust removal frame 4, and a first motor 42 is installed on the bottom of the mounting cross plate 41 by bolts. The output shaft of the first motor 42 passes through the dust removal frame 4 and is fixedly connected to the back of the dust removal rod 5. An electromagnet 43 is installed on the surface of the dust removal frame 4. Through the setting of the first motor 42, the dust removal rod 5 can be driven to rotate at a uniform speed with the output shaft of the first motor 42, forming two symmetrical fan-shaped dust removal surfaces;

[0030] It should be noted that: the first motors 42 on both sides work separately. When the first motor 42 on the left side drives the dust removal rod 5 to rotate from a vertical state to a horizontal state, the first motor 42 on the right side drives the dust removal rod 5 to rotate from a horizontal state to a vertical state.

[0031] Embodiment 2

[0032] See also Figure 6 and Figure 7 As shown, compared with Example 1, as another implementation of the utility model, a guide groove 51 is opened on the back of the dust removal rod 5, and a spring 52 is installed inside the guide groove 51. The other end of the spring 52 is fixedly connected to the bottom of the extension rod 7. Through the setting of the spring 52, the fan-shaped dust removal surface can be expanded to achieve full coverage of the surface of the LED module 2.

[0033] Furthermore, a magnetic sheet 71 is provided on the back of the extension rod 7, and the bottom cross-sectional dimensions of the extension rod 7 match the cross-sectional dimensions of the guide groove 51. When the extension rod 7 is completely received in the dust removal rod 5, the magnetic sheet 71 and the electromagnet 43 cooperate to lock the two in this state, so as to avoid friction between the top of the extension rod 7 and the top surface of the storage groove 11 when the extension rod 7 is received in the storage groove 11.

[0034] It should be noted that when the extension rod 7 is fully retracted into the dust removal rod 5, the spring 52 is compressed and accumulates elastic potential energy. As the dust removal rod 5 tilts, the extension rod 7 is subjected to the elastic force of the spring 52 and gradually moves outward until the extension rod 7 moves to the maximum distance. At this time, the extension rod 7 is blocked by the protrusion on the inner wall of the guide groove 51, and the elastic force of the spring 52 is not completely released.

[0035] Furthermore, countersunk holes 91 are evenly distributed on the surface of the positioning frame 9 , and hooks 92 are evenly arranged between the countersunk holes 91 . Through the cooperation of the hooks 92 and the mounting holes 13 , the frame 1 can be stably suspended in the working position.

[0036] Working principle: First, fix the positioning frame 9 at the specified position with bolts, then install the frame 1 on the positioning frame 9 through the mounting hole 13 and the hook 92, and display the picture through the LED module 2. After using it for a period of time, the first step is to push the dust removal rod 5 out of the storage slot 11 through the electric push rod 3, so that the main dust removal brush 6 and the auxiliary dust removal brush 8 can fit the LED module 2, the second step is to turn off the electromagnet 43, and the third step is to drive the dust removal rod 5 to rotate in the direction of the LED module 2 through the first motors 42 on both sides. During the rotation, the extension rod 7 gradually extends out of the dust removal rod 5 through the spring 52, and then, the LED module 2 is cleaned by the main dust removal brush 6 and the auxiliary dust removal brush 8, and then, the extension rod 7 is pressed back to the dust removal rod 5 through the baffle 12, and the fourth step is to reset the dust removal rod 5 and the extension rod 7 after cleaning. This completes the use process of the rental LED display screen with dust removal function.
