Description

[0001] Technical field

[0002] The utility model relates to the technical field of liquid crystal displays, in particular to a rotatable and positionable liquid crystal display.

[0003] Background technique

[0004] A liquid crystal display uses liquid crystal materials as basic components. Liquid crystal materials are filled between two parallel plates. By applying voltage, the arrangement of internal molecules of the liquid crystal materials is changed to achieve the purpose of blocking light and transmitting light, so as to display images with different shades and in an orderly manner. Moreover, as long as a color filter layer of three primary colors is added between the two flat plates, a color image can be displayed.

[0005] However, for existing liquid crystal displays, vertical or horizontal screen adjustment is sometimes required. However, after rotation, due to the flexible connection of the liquid crystal display itself, it will still rotate under accidental touch, that is, it is too easy to change the state under the action of external force, which is not conducive to the use of the user.

[0025] Specific implementation manner.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1-4 , a liquid crystal screen with rotary positioning, including a display 1. A connecting frame 2 is installed on the back of the display 1. A rotating shaft 3 is vertically installed in the middle of the connecting frame 2. The other end of the rotating shaft 3 is rotatably installed on the support frame 12. Under the rotational connection of the rotating shaft 3, the display 1 can rotate freely so that the display 1 can be placed horizontally or vertically. And the support frame 12 is arranged on the mounting bracket 15. Mounting holes are provided in the mounting bracket 15, and bolts can be taken to pass through the mounting holes for fixing the mounting bracket 15 on the wall.

[0028] Among them, the connecting frame 2 is fixed to the display 1 by bolts, which is convenient for the disassembly and assembly of the display 1 on the connecting frame 2; on the side of the support frame 12 close to the mounting bracket 15, a connecting plate 13 with a top bent in an "L" shape is installed, and the top of the connecting plate 13 is fixed to the support frame 12. And on the side of the mounting bracket 15 close to the support frame 12, a bearing plate 14 with an end bent in an "L" shape is provided. The end of the bearing plate 14 is fixed to the mounting bracket 15, and the inner side of the bearing plate 14 corresponds to the bottom of the connecting plate 13, so that the support frame 12 can be directly hung on the mounting bracket 15, which is convenient for the installation and disassembly between the support frame 12 and the mounting bracket 15.

[0029] Furthermore, a plurality of reinforcing plates are installed on the rotating shaft 3. One side of the reinforcing plate is fixed to the rotating shaft 3, and the other side of the reinforcing plate is in clearance fit with the support frame 12, enhancing the connection strength between the rotating shaft 3 and the support frame 12.

[0030] The first rotary disc 4 is provided with a plurality of U-shaped grooves 5 arranged at intervals along the edge of the first rotary disc 4. The U-shaped grooves 5 are arranged in a radial direction of the first rotary disc 4, and a second rotary disc 7 is provided in parallel on one side of the first rotary disc 4. A toggle rod 8 is vertically installed on the edge of the second rotary disc 7 close to the first rotary disc 4. The toggle rod 8 corresponds to the U-shaped groove 5, and a driving motor 10 is coaxially installed on the other side of the second rotary disc 7 through the driving shaft. The driving motor 10 is arranged in a motor box 11, and the motor box 11 is fixed on the support frame 12, so that the rotation of the rotating shaft 3 is controlled by the toggle rod 8 to toggle the first rotary disc 4 when it is rotated into the U-shaped groove 5. That is, after the toggle rod 8 is rotated out of the U-shaped groove 5, the first rotary disc 4 will lose power and stand still, and can continue to rotate only when the toggle rod 8 is rotated into the U-shaped groove 5 again, so that the rotation of the rotating shaft 3 is intermittent.

[0031] When the display 1 is rotated to a suitable position, a baffle 19 is installed on the rotating shaft 3, and at least one pushing mechanism 16 is provided on the side of the rotating shaft 3, which is tilted toward the rotating shaft 3. One end of the pushing mechanism 16 is fixed to the support frame 12 through a fixing seat 17, and a stop block 18 is installed on the other end of the pushing mechanism 16. The stop block 18 corresponds to the baffle 19. In actual use, the pushing mechanism 16 is an electric push rod or a cylinder, and the stop block 18 is opposite to the connection between the baffle 19 and the rotating shaft 3. The pushing mechanism 16 will push the stop block 18 to press against the baffle 19 and the rotating shaft 3, so that the rotating shaft 3 is braked under the squeezing of the stop block 18, so that the display 1 will not rotate accidentally due to accidental touch.

[0032] Specifically, the plurality of U-shaped grooves 5 are arranged to divide the rotation angle of the display 1 into equal parts. Therefore, there is a waiting time each time the display 1 rotates to a certain angle, that is, the time it takes for the toggle lever 8 to be rotated into the U-shaped groove 5 again. During this waiting time, the pushing mechanism 16 has enough time to press the block 18 against the baffle 19 and the rotating shaft 3, and also provides time for the drive motor 10 to stop operating, thereby ensuring precise control of the rotation angle of the display 1.

[0033] It should be noted that a number of arc-shaped limit grooves 6 are also provided at the edge of the first turntable 4, and the limit grooves 6 are located between two adjacent U-shaped grooves 5, and a limit block 9 corresponding to the limit groove 6 is installed on the second turntable 7. During the period from the toggle rod 8 turning out of the U-shaped groove 5 to the toggle rod 8 turning into the next U-shaped groove 5, the limit block 9 is placed in the limit groove 6, so that the first turntable 4 can be limited to prevent it from accidentally rotating due to reasons such as the deviation of the center of gravity of the display 1, thereby affecting the normal rotation of the rotating shaft 3.

[0034] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
