DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0026] See also Figure 1-6 , a display that is easy to clean, includes a display body 1, a lifting component and a wiping component, the display body 1 is embedded with a display screen 2 on the front, the lifting component includes a cover body 3, a motor 4, a first worm 5, a first worm wheel 6, a second worm 7, a second worm wheel 8, a screw 9 and a guide frame 10, the display body 1 is symmetrically provided with guide frames 10 on the left and right sides, the cover body 3 is provided on two groups of the guide frames 10, the cover body 3 is provided with the motor 4 on the back side, the output end of the motor 4 passes through the cover body 3 and is connected to the first worm 5, the cover body 3 is also provided with a first worm wheel 6 meshing with the first worm 5, and the first worm wheel 6 is symmetrically provided with second worm 7 on the left and right sides. , the cover body 3 is also rotatably provided with a second worm wheel 8 meshing with the corresponding second worm 7 on the left and right sides, the guide frame 10 is rotatably provided with a screw 9, the screw 9 passes through the cover body 3 and is connected to the center of the second worm wheel 8, the wiping assembly includes a guide block 11, a beam 12, an assembly part and a wiping strip 13, the left and right sides of the beam 12 are symmetrically provided with guide blocks 11 slidably connected to the guide frame 10, the guide block 11 is provided with a screw hole threadedly connected to the screw 9, the beam 12 is also provided with a movable groove at one end close to the display screen 2, the movable groove is provided with an assembly part connected to the wiping strip 13, and the wiping strip 13 is in contact with the display screen 2.

[0027] The display screen 2 is embedded in the front of the display body 1. The motor 4 is installed on the back of the cover 3 as a power source. After starting, the output shaft of the motor 4 drives the first worm 5 to rotate. Since the first worm 5 and the first worm wheel 6 are meshed with each other, according to the worm and worm wheel transmission characteristics, the first worm 5 drives the first worm wheel 6 to rotate. The second worm 7 symmetrically arranged on the left and right sides of the first worm wheel 6 rotates synchronously with the first worm wheel 6, and then the second worm 7 meshes with the corresponding second worm wheel 8 to drive the second worm wheel 8 to rotate;

[0028] The screw 9 connected to the center of the second worm gear 8 is installed in the guide frame 10 and passes through the cover body 3 on the top. When the screw 9 rotates, since the guide blocks 11 on both sides of the crossbeam 12 are T-shaped, they are embedded in the lower opening 20 below the guide frame 10 and are threadedly connected with the screw 9 through the screw holes. According to the principle of thread transmission, the rotation of the screw 9 causes the guide block 11 to carry the crossbeam 12 to perform vertical lifting and lowering movements along the guide frame 10. In this process, the guide frame 10 plays a precise guiding role, limiting the crossbeam 12 to move only up and down, avoiding left and right, front and back shaking, and ensuring that the wiping component can stably clean the display screen 2 at different heights;

[0029] An active groove is provided at one end of the crossbeam 12 close to the display screen 2 , in which the assembly part is located, and the wiping strip 13 is in contact with the display screen 2 . As the crossbeam 12 rises and falls, the wiping strip 13 wipes the display screen 2 stably.

[0030] In this embodiment, the fitting includes an elastic member 14, a mounting plate 15, a magnetic strip 16, and a magnetic seat 17. A magnetic seat 17 is provided at one end of the wiping strip 13 away from the display screen 2. A number of elastic members 14 connected to the mounting plate 15 are provided in the movable groove. An installation groove adapted to the magnetic seat 17 is provided on the mounting plate 15. A magnetic strip 16 magnetically connected to the magnetic seat 17 is embedded in the installation groove. Both ends of the elastic member 14 (the spring 18 is sleeved on the telescopic rod 19) are respectively connected to the inner wall of the movable groove and the mounting plate 15. The elastic force of the spring 18 continuously presses the mounting plate 15 towards the display screen 2, so that the wiping strip 13 connected to the magnetic seat 17 through the magnetic strip 16 on the mounting plate 15 can closely fit the surface of the display screen 2 and stably wipe the dirt on the surface of the display screen 2. When it is necessary to clean or replace the wiping strip 13, the bottom wall below the guiding frame 10 is lower than the display body 1. A lower opening 20 is provided below the guiding frame 10. After the cross beam 12 is misaligned with the display body 1, only a certain external force needs to be applied to overcome the magnetic force between the magnetic strip 16 and the magnetic seat 17, and the dirty wiping strip 13 can be removed from the mounting plate 15. After cleaning or replacing with a new wiping strip 13, align the magnetic seat 17 with the magnetic strip 16, and the installation can be quickly completed by relying on the magnetic force. The operation is simple and convenient, without the need to use additional tools, which helps to maintain the good cleaning performance of the wiping strip 13 and thus ensure the wiping effect on the display screen 2.

[0031] The L-shaped auxiliary plate 21 below the display body 1 expands additional space, which is convenient for placing small items such as controllers and remote controls that are interactively used with the display, making the desktop cleaner and more orderly. They can be easily taken when in use, improving the operation convenience. The collection box 22 with an upper opening on the auxiliary plate 21 is stably installed by using a card slot. During the process of wiping the display screen 2, the dust and stains wiped off directly fall into the collection box 22 under the action of gravity, preventing them from scattering everywhere and polluting the desktop. When cleaning the collection box 22 later, just pull it out and pour it out to maintain a clean use environment. The U-shaped protective frame 23 is installed on the auxiliary plate 21, mainly playing a protective role to prevent the lines and interfaces under the display from being accidentally collided or pulled by external objects during daily use, reducing the risk of equipment failure due to line damage and extending the normal service life of the display.
