TECHNICAL FIELD

[0001] The utility model relates to display support field, concretely is adjustable fixed support of liquid crystal display. BACKGROUND

[0002] Display support is a practical accessory that improves office efficiency and comfort by flexibly adjusting the screen position to optimize ergonomic experience. Its core advantage lies in supporting free adjustment of display height, inclination, and rotation angle, adapting to different sitting positions and effectively relieving cervical fatigue. The pneumatic spring or joint arm design makes adjustment smooth and easy, and single-screen or multi-screen combination installation can be achieved. The support is made of aluminum alloy or carbon steel, which is stable, load-bearing, and saves desktop space. It is compatible with 17-32 inch common displays and meets VESA standards. Some products integrate cable management systems to keep the desktop clean. The hole-free clamping installation is suitable for various types of desks and is convenient to install. Whether it is home office, professional design, or e-sports scene, display support can create a personalized and efficient work area, achieving both health and efficiency.

[0003] In our daily office environment, we often encounter situations where we need to have face-to-face communication and discussion with colleagues at the adjacent workstation. In this case, we usually need to adjust the position of the display to better communicate visually with the other party. However, existing display supports, although designed with a rotating shaft to allow users to adjust the inclination angle of the display, i.e., the tilt angle, often lack the function of adjusting the left and right deflection angle of the display. This design limitation leads to certain inconvenience in actual use, as users cannot flexibly adjust the position of the display according to their sitting posture or specific needs during discussion. Therefore, an adjustable fixed support for liquid crystal display is proposed UTILITY MODEL CONTENT

[0004] The utility model aims at providing an adjustable fixed support for liquid crystal display to solve the problems in the prior art.

[0021] 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.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for an adjustable fixed bracket for a liquid crystal display, including a base 1, a support column 2 fixedly installed on the base 1, a connecting sleeve 3 fixedly installed on the upper end of the support column 2, a rotating slip ring 4 provided inside the connecting sleeve 3, an adjustment mechanism 6 rotatably installed at the rotating slip ring 4 on the connecting sleeve 3, and a drive mechanism 7 provided inside the support column 2. By cooperating with the adjustment mechanism 6 and the drive mechanism 7, the tilt angle or yaw angle of the display can be adjusted conveniently and quickly.

[0023] like Figure 3 and Figure 5As shown, the adjusting mechanism 6 comprises an adjusting seat 602 rotatably mounted on the connecting sleeve 3, an adjusting shaft 603 rotatably mounted on the adjusting seat 602, and an installation plate 5 fixedly mounted on the adjusting shaft 603. The adjusting mechanism 6 further comprises a worm wheel 601 fixedly mounted at the middle position of the adjusting shaft 603, and a tooth ring 604 fixedly mounted on the inner wall of the adjusting seat 602. One side of the worm wheel 601 is fixedly provided with a mounting frame 606, and the mounting frame 606 is rotatably provided with a worm 605. The lower end of the worm 605 is fixedly provided with a protrusion 607. The adjusting seat 602 is provided with a bearing, and the adjusting shaft 603 is rotatably mounted on the adjusting seat 602 through the bearing.

[0024] Specifically, when the electromagnet 705 is started, it will immediately generate a magnetic force to attract the iron spring frame 701. With the iron spring frame 701 being attracted, the transmission shaft 706 will immediately start to move upward. During the upward movement of the transmission shaft 706, the protrusion 607 at the lower end of the driving worm 605 will accurately insert into the butt joint groove 708. Once the protrusion 607 is successfully inserted into the butt joint groove 708, the motor 702 can be safely started. Once the motor 702 is started, it will start to drive the worm 605 to rotate. During the rotation of the worm 605, power will be transmitted to the worm wheel 601, so that the worm wheel 601 also starts to rotate. The rotation of the worm wheel 601 will further drive the installation plate 5 mounted on the adjusting shaft 603 to rotate. With the rotation of the installation plate 5, the tilt angle of the display will be automatically adjusted.

[0025] As shown in Figure 3 , Figure 4 and Figure 5 , the driving mechanism 7 comprises a motor 702 and a spring frame 701 fixedly mounted in the support column 2. The transmission shaft 706 is movably mounted on the spring frame 701, and the lower end of the transmission shaft 706 is slidably mounted on the output end of the motor 702. The iron spring seat 704 is rotatably mounted on the transmission shaft 706, and the positioning bearing 709 is mounted on the iron spring seat 704. The reset spring 703 is arranged between the spring frame 701 and the iron spring seat 704. The electromagnet 705 is fixedly mounted above the iron spring seat 704. The gear 707 is fixedly mounted on the transmission shaft 706, and the butt joint groove 708 is formed at the upper end of the transmission shaft 706. The mounting hole is formed in the spring frame 701, and the transmission shaft 706 is movably mounted on the spring frame 701 through the mounting hole.

[0026] Specifically, when the electromagnet 705 is turned off, the reset spring 703 will act immediately, which will pull the iron spring seat 704 back to the initial position. During the reset process, the iron spring seat 704 will further promote the transmission shaft 706 to move downward, which will cause the gear 707 to mesh with the tooth ring 604. Once the gear 707 successfully meshes with the tooth ring 604, the motor 702 can start to work, and the power is transmitted through the rotation of the gear 707. The rotation of the gear 707 will drive the tooth ring 604 to rotate, and the rotation of the tooth ring 604 will further cause the rotation of the adjusting seat 602. The rotation of the adjusting seat 602 is the key step of automatically adjusting the deflection angle of the display, so that the display angle can be adjusted as needed for the user to discuss with colleagues at the adjacent workstations.

[0027] Working principle: Before use, the display can be fixed on the mounting plate 5, and when in use, the electromagnet 705 can be started. After the electromagnet 705 is started, it will attract the iron spring frame 701, so that the transmission shaft 706 moves upward, and after the transmission shaft 706 moves upward, the protrusion 607 at the lower end of the worm 605 will be embedded in the butt joint groove 708. After the protrusion 607 is embedded in the butt joint groove 708, the motor 702 can be started, and after the motor 702 is started, it will drive the worm 605 to rotate. After the worm 605 rotates, it will drive the worm wheel 601 to rotate, and after the worm wheel 601 rotates, it will drive the mounting plate 5 on the adjusting shaft 603 to rotate, thereby automatically adjusting the tilt angle of the display. At the same time, the electromagnet 705 can be turned off, and after the electromagnet 705 is turned off, the reset spring 703 will pull the iron spring seat 704 back to the original position, and after the iron spring seat 704 is reset, it will drive the transmission shaft 706 to move downward, so that the gear 707 meshes with the tooth ring 604. After the gear 707 meshes with the tooth ring 604, the gear 707 can be rotated by the motor 702, and after the gear 707 rotates, it will drive the tooth ring 604 to rotate, and after the tooth ring 604 rotates, it will drive the adjusting seat 602 to rotate, thereby automatically adjusting the deflection angle of the display.
