[0022] See also Figure 1-5 As shown, an anti-glare liquid crystal display screen of the embodiment of the present invention includes a display screen body 1 and a horizontal plate 2. An anti-glare film 11 is affixed to the display end of one side of the display screen body 1, a cleaning layer 22 is fixedly connected to the outer wall of one side of the horizontal plate 2, and slots 201 are provided at both ends of the outer wall of one side of the horizontal plate 2. A sliding rod 23 is fixedly connected between the inner walls of the two slots 201, and the rod walls of the two sliding rods 23 are slidably connected to sliders 24. The tops of one end of the two sliders 24 are fixedly connected to clamping blocks 26, and the inner surfaces of one side of the two clamping blocks 26 are provided with two sliding grooves 27. A spring 25 is fixedly connected between the inner walls of the two slots 201 and the sliders 24, and the springs 25 are both sleeved on the outer ends of the sliding rods 23.

[0023] A sliding cavity 203 is defined on either side of the horizontal plate 2, near the notch 201. A rod slot 204 is staggered between the two sliding cavities 203. A Z-shaped push rod 3 is slidably connected to the inner walls of the two rod slots 204. Two push rods 31 are fixedly connected to the top of one end of each push rod 3. Several tooth grooves 32 are defined on the upper and lower surfaces of the other ends of each push rod 3. A rotating rod 4 is rotatably connected through the middle of the surface of the horizontal plate 2. A transmission gear 41 is fixedly connected to the top of one end of the rotating rod 4, and each transmission gear 41 meshes with the several tooth grooves 32. Fixed blocks 12 are fixedly connected to the upper and lower ends of each side of the display screen body 1. Two slide bars 13 are fixedly connected between the two fixed blocks 12. The outer diameters of the two slide bars 13 match the inner diameters of the slide slots 27. The clamping block 26 slides up and down along the slide bars 13 through the slide slots 27.

[0024] A pull handle 21 is fixedly connected to the outer wall at both ends of the other side of the horizontal plate 2, and a handle 42 is fixedly connected to the top of the other end of the rotating rod 4. Pulling the pull handle 21 can drive the horizontal plate 2 to move, and rotating the handle 42 drives the transmission gear 41 to rotate through the rotating rod 4.

[0027] When the embodiment of the present invention is in use, the anti-glare film 11 provided can prevent glare from occurring on the screen. When a large amount of dirt adheres to the surface of the anti-glare film 11, the handle 21 is pulled to drive the horizontal plate 2 to slide downward. The horizontal plate 2 will slide downward along the slide bar 13 through the clamping blocks 26 at both ends. At this time, the surface of the anti-glare film 11 can be cleaned through the cleaning layer 22.

[0028] When the cross plate 2 needs to be disassembled for maintenance, the rotating handle 42 drives the transmission gear 41 through the rotating rod 4. When the transmission gear 41 engages with a plurality of tooth grooves 32, it drives the two push rods 3 to slide outward respectively. The two push rods 3 contact the slider 24 through the push rod 31. The slider 24 will drive the clamping block 26 to move so that its slide groove 27 disengages from the slide bar 13. At this time, the cross plate 2 can be disassembled for maintenance.
