[0018] Compared with the prior art, the present invention provides a liquid crystal display screen with an anti-glare structure, having the following beneficial effects:

[0019] 1. For the liquid crystal display screen with an anti-glare structure, in order to enrich the wide range of installation location options for the device, when the installation location is a pitted plane, the contact plane of the base decreases in contact area with the plane due to the pitted plane of the selected installation point, resulting in poor stability of the installation base. In this case, start the compensation device and pull out the auxiliary plate from the T-shaped part. At this time, the auxiliary plate cooperates with the fixed seat to compensate for the reduced bottom effective area of the pitted plane, increasing the force-bearing area of the base and making the device more stable during installation, enriching the wide range of installation location options for the device. At the same time, when the auxiliary plate is not needed for bottom compensation, push the auxiliary plate back into the T-shaped part. At this time, the sawteeth cooperate with the roller to realize the upward movement of the roller shaft, and at the same time, the roller rotates on the surface of the sawteeth. When the auxiliary plate moves to the designated position, the groove of the sawteeth cooperates with the telescopic thin rod and spring in the telescopic block to realize the downward extrusion force on the vertical rod. The vertical rod drives the roller to press down, realizing the positioning function of the auxiliary plate, so that the auxiliary plate has positioning and locking properties again after being pushed back into the T-shaped part, preventing misoperation of opening the compensation device due to accidental contact of the user with the auxiliary plate and improving the use stability of the device.

[0020] 2. For the liquid crystal display screen with an anti-glare structure, in order to improve the anti-glare property of the device, when the display screen is not in use, the cover plate closes to the front surface of the display rack, protecting the display screen from being damaged by external impacts, improving the explosion-proof property of the display screen. At the same time, the limit telescopic sleeve cooperates with the strip groove of the display rack to position the cover plate and avoid the shaking of the cover plate. When the display screen needs to be used, the user manually squeezes the limit telescopic sleeve. At this time, the squeezed limit telescopic sleeve loses its limiting effect on the cover plate and cooperates with the rotating column to open the cover plate. At the same time, when the cover plate rotates, magnet one and magnet two attract each other magnetically, realizing the re-positioning of the opened cover plate. At the same time, an anti-glare strip is provided on the inner surface of the opened cover plate, and an anti-glare strengthened glass is provided on the front surface of the display screen to block the glare on the surface of the display screen and improve the anti-glare property of the user.

[0021] 3. For the liquid crystal display screen with an anti-glare structure, in order to enrich the functionality of the device, when the motor starts, it drives the rotating shaft to rotate. The rotation of the rotating shaft drives the first rotating rod to rotate. The first rotating rod cooperates with the second rotating rod to enable the moving block to perform a reciprocating motion in the vertical direction in the movable slot. The reciprocating motion of the moving block in the vertical direction causes the driving block to perform a reciprocating motion in the vertical direction. The reciprocating motion of the driving block in the vertical direction causes the output rod to perform a reciprocating motion in the vertical direction. The reciprocating motion of the output rod in the vertical direction drives the cleaning roller to rotate, realizing the cleaning of the rear surface of the inner wall of the display rack by the cleaning roller. At the same time, the movement of the output rod drives the movement of the support rod, which cooperates with the cleaning block to clean the bottom of the inner wall of the display rack, improving the cleanliness of the inner wall of the display rack, ensuring the working environment of the display screen, and enriching the functionality of the device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] As Figure 1-6As shown in the figure, the present invention provides a technical solution: a liquid crystal display screen with an anti-glare structure, including a base 1, a fixing seat 2 is fixedly connected to the left end of the base 1, a T-shaped member 4 is fixedly connected to the center of the top of the base 1, a moving seat 5 is fixedly connected to the top of the T-shaped member 4, a display frame 6 is movably connected to the top of the moving seat 5, one end of a support rod 17 is fixedly connected to the bottom of the inner wall of the display frame 6, and a display screen 10 is provided at the other end of the support rod 17. A compensation device is provided inside the T-shaped member 4. The compensation device includes an auxiliary plate 3 hinged to the top of the fixing seat 2. A sawtooth 301 is fixedly connected to the right end of the top of the auxiliary plate 3. A horizontal plate 401 is fixedly connected to the left end of the inner wall of the T-shaped member 4. A telescopic block 402 is fixedly connected to the bottom of the horizontal plate 401. A telescopic thin rod 403 is fixedly connected to the top of the inner wall of the telescopic block 402. A spring 404 is sleeved on the outer wall of the telescopic thin rod 403. A vertical rod 405 is fixedly connected to the bottom of the telescopic block 402. A roller 406 is rotatably connected to the bottom of the front surface of the vertical rod 405. A roller 407 is fixedly connected to the outer wall of the roller 406.

[0030] In an embodiment of the present invention, the base 1 is installed at the required installation location. In order to enrich the wide range of installation location options for the device, when the selected installation location is a pitted plane, the contact plane of the base 1 is reduced due to the pitted plane of the selected installation point, resulting in poor stability of the installed base 1. The compensation device is started. The number of the fixing seats 2 and the auxiliary plates 3 is two groups, and each group of the fixing seats 2 and the auxiliary plates 3 is symmetrically distributed on the left and right sides of the central axis in the horizontal direction of the base 1 with the central axis in the horizontal direction of the base 1 as the axis of symmetry, improving the stability of the base 1. The auxiliary plate 3 is pulled out from the T-shaped member 4. At this time, the auxiliary plate 3 cooperates with the fixing seat 2 to compensate for the reduced bottom effective area of the pitted plane, increasing the force-bearing area of the base 1 and making the device more stable when installed, enriching the wide range of installation location options for the device. At the same time, when the auxiliary plate 3 is not needed for bottom compensation, the auxiliary plate 3 is pushed back into the T-shaped member 4. At this time, the sawtooth 301 cooperates with the roller 407 to realize the upward movement of the roller 406, and at the same time, the roller 407 rotates on the surface of the sawtooth 301. When the auxiliary plate 3 moves to the designated position, the cross-sectional area of the groove of the sawtooth 301 is adapted to the cross-sectional area of the roller 407. The groove of the sawtooth 301 cooperates with the telescopic thin rod 403 and the spring 404 in the telescopic block 402 to realize the downward extrusion force on the vertical rod 405. The central axis in the horizontal direction of the telescopic block 402, the central axis in the horizontal direction of the telescopic thin rod 403, and the central axis in the horizontal direction of the vertical rod 405 coincide with each other, improving the stability of the vertical rod 405. The vertical rod 405 drives the roller 407 to press down, realizing the positioning effect on the auxiliary plate 3, so that the auxiliary plate 3 has positioning locking again after being pushed back into the T-shaped member 4, preventing the misoperation of opening the compensation device due to the user accidentally touching the auxiliary plate 3 and improving the use stability of the device.

[0031] In addition, in order to improve the anti-glare property of the device, an anti-glare device is provided on the outer wall of the display stand 6.

A limiting telescopic sleeve 801 is provided on the top of the cover plate 8.

The left end of the fixed block 802 is fixedly connected to a telescopic rod 803. A limiting spring 804 is sleeved on the outer wall of the telescopic rod 803. A first magnet 9 is fixedly connected to the front surface of the display stand 6 near the left end of the rotating column 7. When the display screen 10 is not in use, the cover plate 8 closes to the front surface of the display stand 6, so that the display screen 10 is protected by the cover plate 8, preventing the display screen 10 from being broken due to external impacts, and improving the explosion-proof property of the display screen 10. A strip-shaped groove is provided on the top of the outer wall of the display stand 6 near the upper side of the limiting telescopic sleeve 801, and the cross-sectional area of the strip-shaped groove of the display stand 6 is slightly smaller than the cross-sectional area of the limiting telescopic sleeve 801. At the same time, the limiting telescopic sleeve 801 cooperates with the strip-shaped groove of the display stand 6 to position the cover plate 8, avoiding the shaking of the cover plate 8. When the display screen 10 needs to be used, the user manually squeezes the limiting telescopic sleeve 801. The vertical central axis of the limiting telescopic sleeve 801 is adapted to the vertical central axis of the telescopic rod 803, improving the stability of the telescopic rod 803. At this time, the squeezed limiting telescopic sleeve 801 loses the limiting effect on the cover plate 8 and cooperates with the rotating column 7 to open the cover plate 8. At the same time, when the cover plate 8 rotates, the first magnet 9 and the second magnet 805 attract each other magnetically, providing a re-positioning effect on the opened cover plate 8. At the same time, an anti-glare strip is provided on the inner surface of the opened cover plate 8, and an anti-glare strengthened glass is provided on the front surface of the display screen 10 to block the glare on the surface of the display screen 10, improving the anti-glare property of the user.

[0032] In an embodiment of the present invention, in order to enrich the functionality of the device, an auxiliary device 11 is provided on the rear surface of the inner wall of the display rack 6. The auxiliary device 11 includes a housing 118 fixedly connected to the rear surface of the inner wall of the display rack 6. A motor 12 is provided on the left surface of the housing 118. The output shaft of the motor 12 is fixedly connected to a rotating shaft 111. One end of a rotating rod one 112 is fixedly connected to the outer wall of the rotating shaft 111. The other end of the rotating rod one 112 is hinged to one end of a rotating rod two 113. The other end of the rotating rod two 113 is hinged to a moving block 114. A movable groove 115 is fixedly connected to the bottom of the inner wall of the housing 118. A driving block 116 is fixedly connected to the rear surface of the moving block 114. An output rod 117 is fixedly connected to the bottom of the driving block 116. One end of a support rod 15 is hinged to the front surface of the output rod 117. The other end of the support rod 15 is hinged to a cleaning block 16. One end of a cross bar 13 is fixedly connected to the rear surface of the output rod 117. A cleaning roller 14 is provided at the other end of the cross bar 13. When the motor 12 is started, it drives the rotating shaft 111 to rotate. The rotation of the rotating shaft 111 drives the rotating rod one 112 to rotate. The rotating rod one 112 cooperates with the rotating rod two 113 to realize the reciprocating motion of the moving block 114 in the vertical direction in the movable groove 115. A vertical groove is provided on the rear surface of the movable groove 115, and the cross-sectional area of the vertical groove of the movable groove 115 is adapted to the cross-sectional area of the driving block 116. The driving block 116 penetrates and connects to the movable groove 115. The reciprocating motion of the moving block 114 in the vertical direction enables the driving block 116 to realize the reciprocating motion in the vertical direction. The reciprocating motion of the driving block 116 in the vertical direction enables the output rod 117 to realize the reciprocating motion in the vertical direction. The reciprocating motion of the output rod 117 in the vertical direction drives the cleaning roller 14 to rotate. A number of small top blocks are distributed on the surface of the cleaning roller 14, realizing the cleaning of the rear surface of the inner wall of the display rack 6 by the cleaning roller 14. At the same time, the movement of the output rod 117 drives the movement of the support rod 15 to cooperate with the cleaning block 16 to realize the cleaning of the bottom of the inner wall of the display rack 6, improving the cleanliness of the inner wall of the display rack 6, ensuring the working environment of the display screen 10, and enriching the functionality of the device.

[0033] In the present invention, during use, the base 1 is installed at the required installation location. To enrich the wide range of installation location options for the device, when the selected installation location is a pitted plane, the contact plane of the base 1 has a reduced contact area with the plane due to the pitted plane of the selected installation point, resulting in poor stability of the installed base 1. In this case, the compensation device is activated, and the auxiliary plate 3 is pulled out from the T-shaped part 4. At this time, the auxiliary plate 3 cooperates with the fixed seat 2 to compensate for the reduced effective bottom area of the pitted plane, increasing the force-bearing area of the base 1 and making the device more stable when installed, thus enriching the wide range of installation location options for the device. At the same time, when the auxiliary plate 3 is not needed for bottom compensation, the auxiliary plate 3 is pushed back into the T-shaped part 4. At this time, the saw teeth 301 cooperate with the roller 407 to achieve the upward movement of the roller shaft 406, and at the same time, the roller 407 rotates on the surface of the saw teeth 301. When the auxiliary plate 3 moves to the designated position, the groove of the saw teeth 301 cooperates with the telescopic thin rod 403 and the spring 404 in the telescopic block 402 to achieve a downward squeezing force on the vertical rod 405. The vertical rod 405 drives the roller 407 to press down, realizing the positioning function of the auxiliary plate 3, so that the auxiliary plate 3 regains the positioning and locking property after being pushed back into the T-shaped part 4, preventing the misoperation of opening the compensation device due to the user accidentally touching the auxiliary plate 3 and improving the stability of the device during use. To improve the anti-glare property of the device, when the display screen 10 is not in use, the cover plate 8 closes to the front surface of the display rack 6, protecting the display screen 10 from being damaged by external impacts, thus improving the explosion-proof property of the display screen 10. At the same time, the limit telescopic sleeve 801 cooperates with the strip-shaped groove of the display rack 6 to position the cover plate 8 and avoid the shaking of the cover plate 8. When the display screen 10 needs to be used, the user manually squeezes the limit telescopic sleeve 801. At this time, the squeezed limit telescopic sleeve 801 loses its limiting effect on the cover plate 8 and cooperates with the rotating column 7 to open the cover plate 8. At the same time, when the cover plate 8 rotates, the magnet one 9 and the magnet two 805 attract each other magnetically, realizing the re-positioning of the opened cover plate 8. At the same time, the inner surface of the opened cover plate 8 is provided with anti-glare strips, and the front surface of the display screen 10 is provided with anti-glare strengthened glass to block the glare on the surface of the display screen 10 and improve the anti-glare property of the user. To enrich the functionality of the device, the motor 12 is started to drive the rotation of the rotating shaft 111. The rotation of the rotating shaft 111 drives the rotation of the first rotating rod 112. The first rotating rod 112 cooperates with the second rotating rod 113 to achieve the reciprocating movement of the moving block 114 in the vertical direction in the moving groove 115. The reciprocating movement of the moving block 114 in the vertical direction drives the driven block 116 to achieve the reciprocating movement in the vertical direction. The reciprocating movement of the driven block 116 in the vertical direction drives the output rod 117 to achieve the reciprocating movement in the vertical direction. The reciprocating movement of the output rod 117 in the vertical direction drives the cleaning roller 14 to rotate, realizing the cleaning of the rear surface of the inner wall of the display rack 6 by the cleaning roller 14. At the same time, the movement of the output rod 117 drives the movement of the support rod 15 and cooperates with the cleaning block 16 to clean the bottom of the inner wall of the display rack 6.The cleanliness of the inner wall of the display rack 6 is improved, the working environment of the display screen 10 is ensured, and the functionality of the device is enriched.
