[0002] A liquid crystal display is a type of flat panel display used for screen displays of televisions and computers. The liquid crystal display uses a liquid crystal solution between two pieces of polarizing material. When an electric current passes through the liquid, the liquid crystals rearrange to achieve the purpose of imaging. The advantages of this display are low power consumption, small size, and low radiation.

[0003] For example, the utility model with the application number CN202323206358.3 discloses a liquid crystal display with an anti-glare function. This utility model adaptively adjusts the height of the display screen housing and the anti-glare screen by adjusting the extension distance of the telescopic rod in the telescopic tube, so that the liquid crystal display can be adjusted within a certain range according to actual needs, and can meet the usage requirements of different display heights, with high practicability. However, during the actual adjustment process of this type of liquid crystal display, it is necessary to first loosen the positioning bolts on both sides, and when adjusting, it is also necessary to hold the relatively large display screen housing by hand, which is quite laborious. Moreover, after tightening the positioning bolts on both sides, when experiencing the viewing comfort of the display screen, once it is found that fine-tuning is still required, the above-mentioned relatively many operation steps need to be repeated again, resulting in time-consuming and laborious adjustment.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a liquid crystal display with an anti-glare function is provided. Content of the Utility Model

[0014] The utility model provides a liquid crystal display screen with an anti-glare function, having the following beneficial effects:

[0015] 1. Through the arrangement of the lifting assembly, when adjusting the height of the liquid crystal display screen, only need to rotate the knob, and the two screw rods on both sides can be driven to rotate simultaneously through the driving gear, the gear shaft and the driven gear. And because the support rod will limit the rotation of the lifting sleeve, the height of the lifting sleeve can be controlled, so as to adjust the overall height of the display screen main body, making the adjustment more labor-saving and convenient. Moreover, the protective sleeve can be used to shield and protect the outer side of the screw rod to prevent impurities from adhering to the screw rod and causing jamming.

[0016] 2. Through the arrangement of the rotating assembly, when it is necessary to change the elevation angle of the display screen, only need to loosen the internal thread sleeve. At this time, the rotation of the external thread sleeve can be restricted by using the slider and the sliding groove, so that the external thread sleeve drives the side gear ring to separate from the gear block, and then the connecting ear can rotate on the support rod to adjust the elevation angle of the display screen. And after the adjustment, only need to rotate the internal thread sleeve in the reverse direction, and the side gear ring can be docked with the gear block on the connecting ear to quickly position the adjusted angle to meet different use requirements.

The rotating assembly 5 includes an internal thread sleeve 501 and an external thread sleeve 502. The internal thread sleeve 501 is rotatably connected to the outer side of the middle of the support rod 4, and the external thread sleeve 502 is threadedly connected to the two ends inside the internal thread sleeve 501. Moreover, the internal thread patterns at the two ends inside the internal thread sleeve 501 are opposite. The rotating assembly 5 further includes a slider 503 and a sliding groove 504. The slider 503 is fixed inside the external thread sleeve 502, and the sliding groove 504 is formed on the outer side of the support rod 4. The slider 503 is slidably connected to the support rod 4 through the sliding groove 504. The rotation of the external thread sleeve 502 can be restricted by using the slider 503 and the sliding groove 504. The rotating assembly 5 further includes a side tooth ring 505 and a tooth block 506. The side tooth ring 505 is fixed to one end of the external thread sleeve 502, and the tooth block 506 is arranged on one side of the connecting ear 3. The support rod 4 is slidably connected to the side tooth ring 505, and the number of the side tooth rings 505 is two. By loosening the internal thread sleeve 501, the external thread sleeve 502 can drive the side tooth ring 505 to separate from the tooth block 506, and then the connecting ear 3 can rotate on the support rod 4 to adjust the elevation angle of the display screen main body 1. The tooth blocks 506 are evenly distributed in a circumferential manner on one side of the connecting ear 3, and the tooth blocks 506 are slidably connected to the side tooth ring 505. After adjustment, only by rotating the internal thread sleeve 501 in the reverse direction, the side tooth ring 505 can be docked with the tooth blocks 506 on the connecting ear 3 to quickly position the adjusted angle.

[0023] As Figure 1 and Figure 2As shown in the figure, the lifting assembly 6 is arranged below the support rod 4. The lifting assembly 6 includes a base 601, a knob 602, a driving gear 603, a gear shaft 604, a driven gear 605, a screw rod 606, a lifting sleeve 607 and a protective sleeve 608. The middle of the base 601 is rotatably connected with a knob 602, and the bottom of the knob 602 is connected with a driving gear 603. One side of the driving gear 603 meshes with a gear shaft 604, and both ends of the gear shaft 604 mesh with driven gears 605. The top of the driven gear 605 is fixed with a screw rod 606, and the upper outer side of the screw rod 606 is threadedly connected with a lifting sleeve 607. The gear shaft 604 is rotatably connected with the base 601, and the base 601 is rotatably connected with the screw rod 606. By rotating the knob 602, the screw rods 606 on both sides can be driven to rotate simultaneously through the driving gear 603, the gear shaft 604 and the driven gears 605. Since the support rod 4 restricts the rotation of the lifting sleeve 607, the height of the lifting sleeve 607 can be controlled to adjust the overall height of the display screen main body 1. Protective sleeves 608 are fixed at both ends of the top surface of the base 601. The lifting sleeve 607 is fixedly connected with the support rod 4, and the lifting sleeve 607 is slidably connected with the protective sleeve 608. The protective sleeve 608 is used to shield and protect the outer side of the screw rod 606 to prevent impurities from adhering to the screw rod 606 and causing jamming.

[0024] In summary, for this liquid crystal display with an anti-glare function, during use, first, according to Figure 1 , Figure 2 and Figure 3 the structures shown in the figure, during use, since the anti-glare layer 2 is made of AG glass and has a low reflectivity, it can reduce the interference of external light, reduce screen reflection, improve clarity, increase the comfort of the user, and thus improve the anti-glare performance of the liquid crystal display. Then, during the use process, when it is necessary to adjust the height of the liquid crystal display, only need to rotate the knob 602, and the screw rods 606 on both sides can be driven to rotate simultaneously through the driving gear 603, the gear shaft 604 and the driven gears 605. Since the support rod 4 restricts the rotation of the lifting sleeve 607, the height of the lifting sleeve 607 can be controlled to adjust the overall height of the display screen main body 1. And the protective sleeve 608 can be used to shield and protect the outer side of the screw rod 606. Finally, when it is necessary to change the elevation angle of the display screen main body 1, only need to loosen the internal thread sleeve 501. At this time, the rotation of the external thread sleeve 502 can be restricted by the slider 503 and the chute 504, so that the external thread sleeve 502 drives the side tooth ring 505 to separate from the tooth block 506, and the connecting ear 3 can rotate on the support rod 4 to adjust the elevation angle of the display screen main body 1. After the adjustment, only need to rotate the internal thread sleeve 501 in the reverse direction, and the side tooth ring 505 can be docked with the tooth block 506 on the connecting ear 3 to quickly position the adjusted angle.
