Description

Technical Field

[0001] The present invention relates to the technical field of display screen dust prevention, and specifically to a dust prevention structure for a display screen. Background Art

[0002] A liquid crystal display is an active matrix liquid crystal display driven by thin-film transistors (TFTs). It mainly uses an electric current to stimulate liquid crystal molecules to generate dots, lines, and planes, combined with a backlight tube to form an image. IPS, TFT, and SLCD all belong to subclasses of LCD. The working principle of a liquid crystal display is as follows: Under the action of an electric field, the arrangement direction of liquid crystal molecules changes, causing the light transmittance of an external light source to change (modulation), completing the electro-optical conversion. Then, using different excitations of the R, G, and B primary color signals, through the red, green, and blue primary color filter films, the color reproduction in the time domain and spatial domain is completed.

[0003] During the use of a display screen, when the display screen is powered on, powered off, or comes into contact with external charged objects, the display screen will accumulate static electricity, causing the display screen to often adsorb various dust particles due to the attached static electricity, resulting in the surface of the display screen being dirty. Most existing display screens do not have a dust prevention function. When not in use, external dust easily adheres to the display screen. Over time, the dust penetrates into the display screen, affecting the display effect and service life of the display screen.

[0004] The present invention aims to solve the technical problems existing in the prior art. For this purpose, a dust prevention structure for a display screen is proposed. Summary of the Invention

One end of the lifting block is rotatably connected to a connecting rod, and the other end of the connecting rod is fixedly connected to a lifting rod. The lifting rod is fixedly connected to the dust-proof cloth. A torsion spring is arranged on the cylindrical surface of the connecting rod. One end of the torsion spring is connected to the lifting block, and the other end of the torsion spring is fixedly connected to the lifting rod. The torsion spring is used to apply a torque to the lifting rod. A brush is arranged on the cylindrical surface of the lifting rod, and the brush is used to clean the display screen.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The device drives the dust-proof cloth to be wound and unwound through the rotation drive mechanism. When the drive mechanism rotates, it drives the transmission component to rotate through the drive gear, and the transmission component drives the dust-proof device to descend. That is, the dust-proof device drives the dust-proof cloth to descend through the lifting rod to block the display screen, avoiding dust adhesion on the surface of the display screen when the display screen is idle for a long time. At the same time, during the ascending or descending process of the dust-proof device, the dust-proof device can clean the surface of the display screen through the brush.

[0016] 2. The device is provided with a cleaning device. The cleaning brush can be ensured to fit with the dust-proof cloth under the action of the spring. That is, during the winding process of the dust-proof cloth, the cleaning brush can clean the dust-proof surface of the dust-proof cloth, preventing a large amount of dust from adhering to the dust-proof surface of the dust-proof cloth. At the same time, a limiting component is arranged at one end of the cleaning device. That is, when the cleaning device passes through the through groove, the outer shell frame cancels the support for the limiting component, and the limiting component descends under the action of gravity. The cleaning device can be installed by the cooperation of the limiting component and the limiting block. Conversely, the cleaning device can be disassembled by pushing the limiting component upward, which is convenient for cleaning the cleaning brush. BRIEF DESCRIPTION OF THE DRAWINGS

A through groove 102 is opened at one end of the housing frame 101, and the through groove 102 horizontally penetrates the housing frame 101. The housing frame 101 is slidably connected to the cleaning device 2 through the through groove 102. A driving mechanism 4 is rotatably connected to one side of the housing frame 101.

[0029] Please refer to Figures 2-5 , the driving mechanism 4 includes a rotating rod 401, the rotating rod 401 is rotatably connected to the housing frame 101, a dust-proof cloth 403 is fixedly connected to the cylindrical surface of the rotating rod 401, the other end of the dust-proof cloth 403 is fixedly connected to the dust-proof device 5, and the dust-proof cloth 403 is used for dust-proofing the display screen. A handle 404 is fixedly connected to one end of the rotating rod 401, a driving gear 402 is fixedly connected to the other end of the rotating rod 401, the rotating rod 401 drives the transmission component 3 to rotate through the driving gear 402, the rotating rod 401 is rotated through the handle 404, the dust-proof cloth 403 is wound and unwound when the rotating rod 401 rotates, and at the same time, the rotating rod 401 drives the lead screw 301 to rotate through the meshing of the driving gear 402 and the transmission gear 302.

[0030] Please refer to Figure 2 and Figure 5 , the transmission component 3 includes a lead screw 301, the lead screw 301 is arranged in the sliding groove 104 and is rotatably connected to the housing frame 101.

One end of the insertion rod 201 is provided with a trapezoidal block 602. That is, when the insertion rod 201 penetrates through the through groove 102, the outer shell frame 101 cancels the support for the trapezoidal block 602. That is, the trapezoidal block 602 descends under the action of gravity to limit the leftward movement of the insertion rod 201.

The lifting rod 501 drives the dust-proof cloth 403 to descend to block the display screen, avoiding dust adhesion on the surface of the display screen when the display screen is idle for a long time. When the lifting rod 501 leaves the outer shell frame 101, the lifting rod 501 rotates under the action of the torsion spring 506.

That is, during the process of the lifting rod 501 rising or falling, the brush 502 can clean the surface of the display screen. On the contrary, when the lifting rod 501 rises, the brush 502 tends to be perpendicular under the extrusion of the outer shell frame 101 and the chute 104, which is convenient for the brush 502 and the lifting rod 501 to be received into the outer shell frame 101, avoiding the brush 502 and the lifting rod 501 blocking the display screen and thus affecting the user's viewing. The device is provided with an insertion rod 201. The insertion rod 201 is connected to the outer shell frame 101 through a through groove 102. The cleaning brush 202 can be ensured to be attached to the dust-proof cloth 403 under the action of the spring 203.

At the same time, one end of the insertion rod 201 is provided with a trapezoidal block 602. That is, when the insertion rod 201 penetrates through the through groove 102, the outer shell frame 101 cancels the support for the trapezoidal block 602. That is, the trapezoidal block 602 descends under the action of gravity to limit the leftward movement of the insertion rod 201. At the same time, a limiting block 204 is arranged on one side of the insertion rod 201 to limit the rightward movement of the insertion rod 201, so that the insertion rod 201 can be installed. On the contrary, when the trapezoidal block 602 is pushed upward, the limit can be released, and the insertion rod 201 can be conveniently taken out, so as to facilitate the cleaning of the cleaning brush 202.
