Description

Technical Field

[0001] This utility model relates to the field of liquid crystal display technology, specifically to a liquid crystal display panel rotation mechanism. Background Technology

[0002] A liquid crystal display (LCD) is an active-matrix liquid crystal display driven by thin-film transistors. It primarily uses electrical current to stimulate liquid crystal molecules to create dots, lines, and surfaces, which, in conjunction with backlighting, form the image. IPS, TFT, and SLCD are all subcategories of LCDs.

[0003] In existing technologies, the bracket is usually connected to the LCD panel. However, in actual use, since the monitor's connector is connected to the bracket via a threaded locking mechanism, adjusting the monitor's angle requires considerable physical effort from the user, making the operation inconvenient. Furthermore, after repeated rotations, the threaded locking mechanism is prone to loosening, which has certain limitations. Therefore, it is necessary to improve the LCD panel rotation mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a liquid crystal display panel rotation mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a liquid crystal display panel rotation mechanism, including a base, a stand fixedly installed on the top of the base, an adjustment mechanism inside the base, and a blocking mechanism inside the base.

[0006] Preferably, the adjustment mechanism includes a rotating shaft rotatably mounted on the bottom inner wall of the base. A handwheel is fixedly mounted on the top of the rotating shaft. A first bevel gear is fixedly mounted on the outside of the rotating shaft. A second bevel gear meshes with the outside of the first bevel gear. A threaded rod is fixedly mounted on the back of the second bevel gear. The threaded rod is rotatably mounted to the base. A sliding plate is threaded onto the outside of the threaded rod. A limit post is fixedly mounted on the inner wall of the base. Toothed plates are fixedly mounted on both ends of the sliding plate. Gears mesh with the outside of the toothed plates. The gears are rotatably mounted to the base. A first rotating column is fixedly mounted inside the gear. A transmission belt is driven by a pulley to the outside of the first rotating column. A second rotating column is rotatably mounted inside the stand. The outside of the second rotating column is driven by a pulley and a transmission belt. A rotating seat is fixedly mounted outside the second rotating column. A display connection plate is fixedly mounted on the front of the rotating seat to facilitate angle adjustment of the LCD panel.

[0007] Preferably, the inside of the skateboard has a through hole at the position corresponding to the limiting post, and the limiting post is slidably installed in the through hole to facilitate the smooth movement of the skateboard.

[0008] Preferably, the blocking mechanism includes a connecting column, which is fixedly installed on the bottom inner wall of the base. A lifting plate is slidably installed on the outside of the connecting column. A spring is fixedly installed between the bottom of the lifting plate and the base. A blocking cylinder is fixedly installed on the outside of the lifting plate. A pressure block is fixedly installed on the outside of the blocking cylinder. A baffle is fixedly installed on the inner wall of the blocking cylinder to facilitate blocking the handwheel and prevent the handwheel from being accidentally touched and rotating.

[0009] Preferably, the base has a through hole at the position corresponding to the shielding cylinder, and the shielding cylinder is slidably installed in the through hole to facilitate the lifting and lowering of the shielding cylinder.

[0010] Preferably, a through hole is provided inside the baffle at a position corresponding to the rotating shaft, and the rotating shaft is movably installed in the through hole to facilitate the lifting and lowering of the baffle and the rotation of the rotating shaft.

[0011] Compared with the prior art, the present invention provides a liquid crystal display panel rotation mechanism, which has the following beneficial effects:

[0012] 1. The LCD panel rotation mechanism, through its adjustable mechanism, facilitates the installation of the LCD monitor via the monitor connecting plate. Rotating the handwheel moves the sliding plate attached to the threaded rod, which in turn moves the gear plate, allowing the gear and the first rotating column to rotate. With the assistance of the transmission belt, the rotating seat and the monitor connecting plate rotate, thus facilitating angle adjustment of the LCD monitor. This allows for easy rotation of the LCD monitor without requiring excessive physical effort from the user, making operation convenient.

[0013] 2. The LCD panel rotation mechanism, through the setting of the blocking mechanism, can easily block the handwheel during use, thereby preventing the handwheel from rotating due to external force, thus ensuring the stability of the LCD. By pressing the pressure block to make it contact the base, the lifting plate can squeeze the spring, which facilitates the downward movement of the blocking cylinder and makes it easier to rotate the handwheel.
