[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-6 The privacy LCD screen shown includes an adjustment mechanism 1, which further includes a rear frame 101. A display body 102 is slidably connected to the inner wall of the rear frame 101. An adjustment cylinder 103 is fixedly connected to the rear side of the rear frame 101. A front frame 201 is provided on the front side of the adjustment mechanism 1, and a privacy film 202 is fixedly connected to the inner wall of the front frame 201. In the privacy mechanism 2, two positioning grooves 203 are formed on the front side of the rear frame 101, and two connecting plates 204 are fixedly connected to the rear side of the front frame 201. The rear sides of both connecting plates 204 extend into the corresponding positioning grooves 203 and are slidably connected to them. The adjustment mechanism 1 also includes a sliding connection for adjusting... A support cylinder 104 is attached to the inner wall of the cylinder 103. A base 105 is fixedly connected to the bottom of the support cylinder 104. A support plate 106 is fixedly connected to the inner wall of the adjusting cylinder 103. A threaded rod 107 is threadedly connected to the inner wall of the support cylinder 104. The top end of the threaded rod 107 passes through the support plate 106 and is rotatably connected to the support plate 106. A bevel gear 108 is fixedly connected to the top end of the threaded rod 107. A rotating shaft 109 is rotatably connected to the inner wall of the adjusting cylinder 103. The rear end of the rotating shaft 109 extends to the outside of the adjusting cylinder 103. A bevel gear 110 is fixedly connected to the rotating shaft 109. The bevel gear 110 meshes with the bevel gear 108. A knob 111 is fixedly connected to the rear end of the rotating shaft 109.

[0026] Rotating knob 111 in the forward direction causes shaft 109 to rotate, which in turn drives bevel gear 110 to rotate. Bevel gear 110 then drives bevel gear 108 to rotate, which in turn drives threaded rod 107 to rotate. The rotation of threaded rod 107 causes support plate 106 to move upwards, which in turn drives adjusting cylinder 103 to move upwards. This, in turn, causes adjusting cylinder 103 to move rear frame 101 and display screen body 102 upwards. The height of display screen body 102 can be adjusted via adjusting mechanism 1 to accommodate different user heights and sitting postures. Significant differences in habits can be precisely adapted to individual needs, helping users maintain a natural and comfortable sitting posture, preventing prolonged head tilting or looking down due to improper screen height, avoiding excessive tension and fatigue in the neck, shoulders, and back muscles, and keeping the body in a comfortable state throughout use, greatly improving work and study efficiency. At the same time, the appropriate height ensures that the eyes gaze at the screen at the most appropriate angle, reducing unnecessary adjustment movements of the eye muscles, reducing eye fatigue, effectively preventing vision problems such as myopia and astigmatism, and cleverly avoiding glare and reflections caused by ambient light on the screen, creating an excellent visual environment for the eyes.

[0027] The privacy mechanism 2 also includes two extension blocks 205 fixedly connected to the left and right sides of the rear frame 101. Each of the two extension blocks 205 has two sliding grooves 206 inside. The privacy mechanism 2 also includes positioning pins 207 slidably connected to the inner walls of several sliding grooves 206. Each of the several positioning pins 207 is fixedly connected to a limiting plate 208. One end of each of the several positioning pins 207 passes through the corresponding connecting plate 204 and is slidably connected to the corresponding connecting plate 204. The other end of each of the several connecting plates 204 extends to the outside of the corresponding extension block 205. The privacy mechanism 2 also includes springs 209 wrapped around the several positioning pins 207. One end of each of the several springs 209 is fixedly connected to the corresponding limiting plate 208. The other end of each of the several springs 209 is fixedly connected to the inner wall of the corresponding sliding groove 206. The privacy mechanism 2 also includes a fixing plate 210 fixedly connected between two corresponding positioning pins 207. Each of the two fixing plates 210 is threadedly connected to the corresponding extension block 205 with two bolts 211.

[0028] First, insert the two connecting plates 204 into their respective positioning slots 203. After the connecting plates 204 are inserted into the positioning slots 203, press down the two fixing plates 210, causing the two fixing plates 210 to drive the corresponding positioning pins 207 into their respective connecting plates 204, thereby restricting the connecting plates 204 so that they cannot move. When the positioning pins 207 move, they will drive the limiting plate 208 to move. When the limiting plate 208 moves, it will drive the corresponding spring 209 to stretch. Finally, the fixing plate 210 and the corresponding extension block 205 are fixed by bolts 211. The anti-peeping mechanism 2 provides anti-peeping protection for the display screen body 102, thereby effectively protecting personal privacy space and creating an exclusive visual territory for users. This allows them to browse content without any worries when using electronic devices in public places, significantly enhancing their sense of psychological security and privacy. It also greatly reduces visual interference from the surrounding environment, allowing users to concentrate fully when handling various tasks, improving both focus and efficiency, and effectively preventing security incidents such as emergency handling caused by information leakage.

[0029] The working principle of the privacy LCD screen provided by this utility model is as follows: Rotating the knob 111 in the forward direction causes the rotating shaft 109 to rotate. The rotating shaft 109 then drives the second bevel gear 110 to rotate. The second bevel gear 110 then drives the first bevel gear 108 to rotate. The first bevel gear 108 then drives the threaded rod 107 to rotate. Since the support cylinder 104 is fixed, the threaded rod 107 moves upwards in the threaded engagement with the inner wall of the support cylinder 104. This upward movement of the threaded rod 107 drives the support plate 106 to move upwards, thereby... The support plate 106 drives the adjusting cylinder 103 to move upward, which in turn causes the adjusting cylinder 103 to drive the rear frame 101 and the display screen body 102 to move upward. When the knob 111 is turned in the reverse direction, the principle is the same as when the knob 111 is turned in the forward direction, which causes the rear frame 101 and the display screen body 102 to move downward. Thus, the height of the display screen body 102 can be adjusted by turning the knob 111 in the forward and reverse directions, so that different users can adjust the height of the display screen body 102 according to their own height and sitting posture, so that the display screen body 102 is always at the most suitable height.

[0030] When installing the rear frame 101, the display body 102, the front frame 201, and the privacy film 202, first place the display body 102 inside the rear frame 101, then place the front frame 201 in front of the rear frame 101 so that the privacy film 202 is located on the screen of the display body 102. When the front frame 201 is placed in front of the rear frame 101, the two connecting plates 204 are respectively inserted into the corresponding positioning slots 203. After the connecting plates 204 are inserted into the positioning slots 203, press the two fixing plates 210 so that the two fixing plates 210 respectively drive the corresponding... The positioning pin 207 is inserted into the corresponding connecting plate 204, thereby restricting the connecting plate 204 so that it cannot move. When the positioning pin 207 moves, it will drive the limiting plate 208 to move. When the limiting plate 208 moves, it will drive the corresponding spring 209 to stretch. Finally, the fixing plate 210 and the corresponding extension block 205 are fixed by bolts 211, thereby connecting and fixing the front frame 201 and the rear frame 101, so that the rear frame 101 and the front frame 201 can be disassembled and installed. At the same time, the privacy film 202 is used to protect the display screen body 102 from privacy.

[0031] Compared with related technologies, the privacy LCD screen provided by this utility model has the following beneficial effects:

[0032] This utility model provides a privacy-protecting LCD screen. When the device is needed, rotating the knob 111 forward causes the rotating shaft 109 to rotate, which in turn drives the second bevel gear 110 to rotate. The second bevel gear 110 then drives the first bevel gear 108 to rotate, which in turn drives the threaded rod 107 to rotate. The threaded rod 107 then moves the support plate 106 upward, which in turn moves the adjusting cylinder 103 upward. This causes the adjusting cylinder 103 to move the rear frame 101 and the display screen body 102 upward, allowing the height of the display screen body 102 to be adjusted via the adjusting mechanism 1. It can adapt to the significant differences in height and sitting habits of different users, accurately adapt to individual needs, help users maintain a natural and comfortable sitting posture, prevent prolonged head tilting or looking down caused by improper screen height, avoid excessive tension and fatigue of neck, shoulder and back muscles, keep the body in a comfortable state during use, and greatly improve work and study efficiency. At the same time, the appropriate height can ensure that the eyes gaze at the screen at the most appropriate angle, reduce unnecessary adjustment movements of the eye muscles, reduce eye fatigue, effectively prevent vision problems such as myopia and astigmatism, and cleverly avoid glare and reflections caused by ambient light on the screen, creating an excellent visual environment for the eyes.

[0033] First, insert the two connecting plates 204 into their respective positioning slots 203. After the connecting plates 204 are inserted into the positioning slots 203, press down the two fixing plates 210, causing the two fixing plates 210 to drive the corresponding positioning pins 207 into their respective connecting plates 204, thereby restricting the connecting plates 204 so that they cannot move. When the positioning pins 207 move, they will drive the limiting plate 208 to move. When the limiting plate 208 moves, it will drive the corresponding spring 209 to stretch. Finally, the fixing plate 210 and the corresponding extension block 205 are fixed by bolts 211. The anti-peeping mechanism 2 provides anti-peeping protection for the display screen body 102, thereby effectively protecting personal privacy space and creating an exclusive visual territory for users. This allows them to browse content without any worries when using electronic devices in public places, significantly enhancing their sense of psychological security and privacy. It also greatly reduces visual interference from the surrounding environment, allowing users to concentrate fully when handling various tasks, improving both focus and efficiency, and effectively preventing security incidents such as emergency handling caused by information leakage.
