[0002] Liquid crystal display is an active matrix liquid crystal display driven by thin film transistors. It mainly uses electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces, which are combined with the back light tubes to form the picture.

[0003] Its working principle is that under the action of the electric field, the arrangement direction of the liquid crystal molecules changes, the transmittance of the external light source changes (modulation), and the electro-optical conversion is completed. Then, the different excitations of the three primary color signals of R, G, and B are used through the three primary color filters of red, green, and blue to complete the color reproduction in the time domain and space domain.

[0004] Most existing liquid crystal display screens have fixed angles, and cannot be adjusted according to user needs during use, which makes it difficult to improve the practicality of the liquid crystal display screen.

[0005] Based on this, the present invention designs a liquid crystal display screen with adjustable tilt angle to solve the above problems. Utility Model Content

[0008] Preferably, the support frame is U-shaped and does not contact the display screen body, and the side area of ​​the support plate is smaller than the side area of ​​the support frame.

[0009] Preferably, the connection hole passes through the support frame and the support plate, and the bolt passes through the support frame and the support plate, and the anti-slip sheet fits against the outer wall of the support frame.

[0010] Preferably, the electric control push rod is installed in parallel with the support plate, and the electric control push rod is controlled by a remote control, and the electric control push rod and the support plate are on the same circumferential surface.

[0011] Preferably, the limiting rods are vertically installed with the upper top plate, and there are two limiting rods. The bottoms of the two limiting rods are both sleeved with limiting pads, and the limiting pads are in contact with the upper surface of the support plate.

[0012] Preferably, when the support plate is rotated to an angle of 40 degrees in the support frame, the upper surface of the support plate contacts the limit pad, and when the support plate remains vertical, it does not contact the upper top plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model is that when the angle of the display screen body needs to be adjusted during use, the electric push rod is extended by the remote control to apply force to the push block and the rubber block.

An upper top plate 12 is fixedly installed on the inner wall of the support frame 2, and a limit rod 13 is fixedly installed on the bottom of the upper top plate 12. The bottom of the limit rod 13 is sleeved with a limit pad 14, and a display screen body 15 is fixedly installed at one end of the support plate 3. In this embodiment, a counterweight block can be placed on the base 1 or fixed to the placement end by bonding or other connection methods as needed to keep the center of gravity stable and prevent tipping during angle adjustment.

[0022] Preferably, the support frame 2 is U-shaped, and the support frame 2 does not contact the display screen body 15. The side area of ​​the support plate 3 is smaller than the side area of ​​the support frame 2. In this embodiment, the U-shaped setting of the support frame 2 enables the support plate 3 to rotate in a circular motion, and the display screen body 15 will not cause friction or collision with the support frame 2, thereby reducing property loss.

[0023] Preferably, the connecting hole 4 passes through the support frame 2 and the support plate 3, and the bolt 5 passes through the support frame 2 and the support plate 3, and the anti-slip sheet 7 fits against the outer wall of the support frame 2. In this embodiment, the support plate 3 is stably mounted on the support frame 2 by the bolt 5, and can only be rotated along the outer edge of the bolt 5. The anti-slip sheet 7 prevents the fixing nut 6 from falling off the bolt 5, thereby maintaining the stable installation of the bolt 5.

[0024] Preferably, the electric push rod 9 is installed parallel to the support plate 8, and the electric push rod 9 is controlled by a remote control. The electric push rod 9 and the support plate 3 are on the same circumferential surface. In this embodiment, the control device in the remote control can control the electric push rod 9 to extend and retract, which is convenient for adjustment, and the electric push rod 9 can always apply force to the support plate 3.

[0025] Preferably, the limit rod 13 is installed vertically with the upper top plate 12, and there are two limit rods 13. The bottoms of the two limit rods 13 are both sleeved with limit pads 14, and the limit pads 14 are in contact with the upper surface of the support plate 3. In this embodiment, the limit rod 13 prevents the support plate 3 from continuing to flip upward, and the limit pads 14 can buffer the contact surface between the limit rod 13 and the support plate 3, thereby reducing the collision and friction between the support plate 3 and the limit rod 13.

[0026] Preferably, when the support plate 3 is rotated to an angle of 40 degrees in the support frame 2, the upper surface of the support plate 3 contacts the limit pad 14, and when the support plate 3 remains vertical, it does not contact the upper top plate 12. In this embodiment, when the support plate 3 is rotated to an angle of 40 degrees, its upper surface contacts the limit pad 14, and its lower surface contacts the electric control push rod 9, thereby maintaining the stable installation of the display screen body 15. When the support plate 3 drives the display screen body 15 to remain vertical, it will not be affected by the upper top plate 12 and can be stably maintained in an upright position for use.

[0027] A specific application of this embodiment is:

[0028] When the angle of the display screen body 15 needs to be adjusted, the electric push rod 9 is extended by the remote control, thereby applying force to the push block 10 and the rubber block 11. Since the rubber block 11 is elastic, it can be fully stretched by the electric push rod 9. When the electric push rod 9 is stretched to contact the support plate 3 and the support plate 3 reaches an angle of 40 degrees, the upper surface of the support plate 3 contacts the limit pad 14 and is further limited by the limit rod 13 to prevent the support plate 3 from continuing to flip over.

[0029] In summary, through the structures such as the support frame 2, support plate 3, electric push rod 9, rubber block 11, limit rod 13 and limit pad 14, the angle of the display screen body 15 can be adjusted without manual operation, which is convenient and quick, and the inclination angle of the display screen body 15 can be adjusted according to needs.
