Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically to a liquid crystal display with an adjustable tilt angle. Background Technology

[0002] Liquid crystal displays (LCDs) are among the most widely used display devices today. The main principle of an LCD is to use an electric current to stimulate liquid crystal molecules to create dots, lines, and surfaces, which, together with a backlight, form an image. Liquid crystal is a substance between a solid and a liquid. It cannot emit light itself, but it can generate an electric field by changing the voltage, causing the liquid crystal molecules to change their arrangement, thereby controlling the passage and blocking of light to achieve the purpose of displaying images.

[0003] According to patent number 201120238525.0 published on the China Patent Website, this utility model discloses a base for a liquid crystal display (LCD), including a chassis. The chassis contacts a placement surface for placing the LCD. The base also includes a suction cup connected to the chassis and located between the placement surface and the chassis, with its suction port facing the placement surface. This utility model also provides an LCD, including a base for supporting the LCD, the chassis including a chassis that contacts a placement surface for placing the LCD. The base also includes a suction cup connected to the placement surface. The present invention provides a base and a liquid crystal display (LCD) display, with a suction cup located between the placement plane and the base, and the suction cup facing the placement plane. By setting a suction cup at the bottom of the LCD display base, the stability of the LCD display is improved while maintaining a reasonable proportion and aesthetic appearance of the base, and the cost can be reduced. However, the support frame of the display is fixedly connected to the screen, which can cause discomfort when the user is too high when viewing the display. The user needs to raise the bottom of the display to adjust the viewing angle, which reduces the practicality of the display.

[0004] Therefore, the monitor needs to be improved to prevent the situation where the monitor cannot be adjusted to fit the viewing angle of users who are too tall. Utility Model Content

A turntable 8 is fixedly connected to the surface of the rotating rod 6. A traction rod 9 is fixedly connected to the left side of the front of the turntable 8. A pull rod 10 is sleeved on the surface of the traction rod 9. A push plate 11 is movably connected to the top of the pull rod 10 through a rotating shaft. An insert plate 12 is fixedly connected to the top of the push plate 11.

[0024] refer to Figure 4 The surface of the rotating block 7 is provided with anti-slip grooves 13, and a retaining sleeve 14 is fitted on the surface of the rotating block 7. The back of the retaining sleeve 14 contacts the front of the support frame 3. Guide rods 15 are provided on both sides of the top of the limiting sleeve 5. The top of the guide rod 15 extends through to the bottom of the retaining sleeve 14 and is slidably connected to the limiting sleeve 5. Support plates 16 are fixedly connected to the top and bottom of the guide rod 15. The back of the support plate 16 is fixedly connected to the front of the support frame 3. A spring rebounder 17 is fitted on the surface of the guide rod 15.

[0028] refer to Figure 3 A torsion spring 19 is fitted on the surface of the rotating rod 6. The back of the torsion spring 19 is fixedly connected to the front of the turntable 8, and the front of the torsion spring 19 is fixedly connected to the inner wall of the support frame 3.

[0029] As a technical optimization of this utility model, by setting the torsion spring 19, the rotating rod 6 can be automatically rotated, thereby improving the performance of the rotating rod 6.

[0030] refer to Figure 3A stop block 20 is fixedly connected to the front of the traction rod 9, and the back of the stop block 20 is in contact with the front of the pull rod 10.

[0031] As a technical optimization of this utility model, by setting a stop 20, the pull rod 10 can be limited to prevent the pull rod 10 from detaching from the traction rod 9 when moving.

[0032] refer to Figure 3 Friction pads 21 are fixedly connected to both sides of the push plate 11, and the surface of the friction pads 21 is in contact with the inner wall of the support frame 3.

[0033] As a technical optimization of this utility model, by setting the friction pad 21, the push plate 11 can be in closer contact with the inner wall of the support frame 3, thereby increasing the contact area between the push plate 11 and the support frame 3.

[0034] The working principle and usage process of this utility model are as follows: First, rotate the rotating block 7. The rotating block 7 drives the rotating rod 6 to rotate, the rotating rod 6 drives the turntable 8 to rotate, and the turntable 8 drives the traction rod 9 to rotate. The traction rod 9 pulls the pull rod 10 downwards, and the pull rod 10 drives the push plate 11 and the insert plate 12 downwards, causing the insert plate 12 to move away from the limiting sleeve 5. After moving away, the spring force of the spring return device 17 drives the sleeve 14 upwards, causing the sleeve 14 to fit onto the surface of the rotating block 7 and limit its movement. After limiting its movement, the mounting block 2 is flipped upwards by the pin 4. The mounting block 2 drives the display screen 1 to flip upwards. After rotating to the designated position, the sleeve 14 is pulled in the opposite direction to move away from the rotating block 7. After moving away, the spring force of the torsion spring 19 drives the rotating rod 6 and the turntable 8 to rotate in the opposite direction. The turntable 8 drives the traction rod 9 to rotate in the opposite direction, and the traction rod 9 pushes the push plate 11 and the insert plate 12 upwards, causing the insert plate 12 to insert into the interior of the limiting sleeve 5 and limit the angle of the rotated display screen 1.

[0035] In summary: This adjustable tilt LCD monitor, by setting the limiting sleeve 5, mounting block 2, and pin 4, can adjust the display angle of the screen 1, improving the practicality of the screen 1; by setting the rotating block 7, rotating rod 6, turntable 8, traction rod 9, pull rod 10, push plate 11, and insert plate 12, it can limit the rotation of the screen 1, preventing the screen 1 from shaking after rotation; by setting the clamping sleeve 14 and guide rod 15, it can limit the rotating block 7, preventing the rotating block 7 from rotating back. Thus, it possesses the advantage of adjustable angle and solves the problem that the monitor's support frame is fixedly connected to the screen, which leads to discomfort for users when viewing the monitor if they are too high, requiring users to raise the bottom of the monitor to adjust the viewing angle, reducing the monitor's practicality.
