Technical Field

[0001] This utility model relates to the field of display screen installation technology, specifically a movable mounting bracket for display screens. Background Technology

[0002] With the development of display screen technology, displays have a wide range of applications. They are not only used as tools for users to watch movies or TV series, but also as advertisements, placed in front of shops or restaurants. During the installation process, they need to be lifted and installed using mounting brackets.

[0003] For example, patent application number 201820124691.X published on the China Patent Network, entitled "A Movable Display Screen Mounting Bracket," includes a support rod. A base plate is welded to the outer wall of the middle section of the support rod, on which a screen is placed. A limit block is fixed to the top of the support rod with screws. A bracket is provided on the side wall of the support rod, and a movable rod is hinged to the bracket. One end of the movable rod extends into the support rod and is hinged to a connecting rod. One end of the connecting rod is hinged to a movable block, and one end of the movable block is equipped with a clamping element. A roller seat is provided at the bottom of the support rod, and a rotating shaft is interference-fitted to the roller seat via bearings. Rollers are fixed to both ends of the rotating shaft via threads, and a limit band is provided on the outer wall of the rotating shaft. This utility model utilizes the movable rod to control the contact between different parts of the limit band and the rotating shaft. By switching between three modes, it can be customized according to customer needs, thus achieving flexible application.

[0004] However, the existing mounting brackets have a relatively simple structure, requiring the display screen to be connected to the bracket first. When the display screen is wall-mounted, the connection between the display screen and the bracket will affect the disassembly and separation of the bracket, interfering with the separation efficiency.

[0005] Therefore, the display screen needs to be redesigned and modified to use a movable mounting bracket. Utility Model Content

[0028] 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.

[0029] like Figures 1 to 4 As shown, the present invention provides a movable mounting bracket for a display screen, including a base 1;

[0030] The support frame 2 is set on top of the base 1;

[0031] The display screen body 3 is placed on top of the support frame 2;

[0032] Both sides of the top of the support frame 2 are fixedly connected to the connecting blocks 4. The surface of the connecting blocks 4 is movably connected to the crank 5 via the lifting pin. The side of the crank 5 away from the connecting blocks 4 extends to the outside of the display screen body 3 and is fixedly connected to the limiting wheels 6 located on both sides of the display screen body 3. The inner sides of the limiting wheels 6 are in contact with the left and right sides of the display screen body 3 respectively. The surface of the base 1 is provided with a transmission structure 7. The transmission structure 7 can drive the support frame 2 to rise and control the crank 5 to swing during the rising process.

[0033] refer to Figure 2 The transmission structure 7 includes a connecting frame 8 fixedly connected to the surface of the base 1. The top of the base 1 is movably connected to a screw 9 located inside the connecting frame 8 via a bearing. A lifting plate 10 is threadedly connected to the surface of the screw 9. The back of the lifting plate 10 is fixedly connected to the front of the support frame 2. A rotating wheel 11 is fixedly connected to the top of the screw 9.

[0034] As a technical optimization of this utility model, the rotating wheel 11 drives the support frame 2 to rise, thereby realizing the lifting function of the display screen body 3, so that the height of the display screen can be flexibly adjusted to meet the usage needs of different scenarios.

[0035] refer to Figure 4 A pressing rod 12 is fixedly connected to the back of the connecting frame 8. The pressing rod 12 extends from the side away from the connecting frame 8 to the front of the connecting block 4. The front of the crank 5 extends through to the front of the connecting block 4 and is fixedly connected to a force-bearing rod 13. The inner side of the force-bearing rod 13 contacts the surface of the pressing rod 12. During the upward movement of the crank 5, the force-bearing rod 13 can contact the pressing rod 12 and be pushed by the pressing rod 12 to carry the crank 5 to swing.

[0036] As a technical optimization of this utility model, through the design of the extrusion rod 12 and the force rod 13, when the lifting plate 10 rises, the force rod 13 will be pushed by the extrusion rod 12, thereby driving the crank 5 to swing, realizing the automatic adjustment of the position of the limit wheel 6 during the lifting process, ensuring that the display screen body 3 is stably and safely fixed on the mounting frame.

[0037] refer to Figure 1 Guide rods 14 are fixedly connected to both sides inside the connecting frame 8, and the lifting plate 10 is sleeved on the surface of the guide rods 14 and slidably connected to the guide rods 14.

[0038] As a technical optimization of this utility model, the guide rod 14 makes the lifting plate 10 more stable during the lifting process, preventing the lifting plate 10 from shaking or shifting, and improving the stability and safety of the entire mounting frame.

[0039] refer to Figure 2 Limiting plates 15 are provided on both sides of the bottom of the support frame 2. The side of the limiting plate 15 closest to the support frame 2 can penetrate the support frame 2 and extend to both sides of the display screen body 3.

[0040] As a technical optimization of this utility model, by setting the limiting plate 15, the position of the display screen body 3 can be further fixed, preventing the display screen body 3 from shifting or tilting during the lifting process, thereby enhancing the stability and reliability of the mounting frame.

[0041] refer to Figure 2 The limiting plate 15 extends through one end of the bearing frame 2 to the inside of the crank 5. Both sides of the limiting plate 15 are fixedly connected to the slide rod 16 located inside the crank 5, and the slide rod 16 is slidably connected to the crank 5.

[0042] As a technical optimization of this utility model, the sliding connection between the slide rod 16 and the crank 5 enables the limiting plate 15 to maintain a stable relative position with the crank 5 while following the lifting plate 10 upward. This ensures the stable fixation of the display screen body 3 and makes the structure of the entire mounting bracket more compact and reasonable.

[0043] The working principle and usage process of this utility model are as follows: The display screen body 3 is placed on top of the support frame 2, which is fixed by the base 1. Connecting blocks 4 are fixedly connected to both sides of the top of the support frame 2. The connecting blocks 4 are movably connected to the crank 5 through the pin shaft. The other end of the crank 5 extends to the outside of the display screen body 3 and is fixedly connected to the limit wheel 6. The inner side of the limit wheel 6 contacts the left and right sides of the display screen body 3, and at this time it does not play the role of fixing the display screen. When it is necessary to adjust the height of the display screen or disassemble it, the user can start the transmission structure 7 by rotating the rotating wheel 11 on the surface of the base 1. The rotating wheel 11 is fixedly connected to the screw 9, which is movably connected to the top of the base 1 through the bearing. When the rotating wheel 11 is rotated, the screw 9 rotates accordingly. The rotation of the screw 9 drives the threaded lifting plate 10 to rise. The back of the lifting plate 10 is fixedly connected to the front of the support frame 2, so the support frame 2 will also rise accordingly. During the rising process, the lifting plate 10 slides along the guide rod 14 inside the connecting frame 8 to ensure the stability of the lifting process. As the support frame 2 rises, the connecting blocks 4 also rise accordingly. During the upward movement of the crank 5 on the connecting block 4, it is subjected to the action of the compression rod 12. The compression rod 12 is fixed to the back of the connecting frame 8. When the crank 5 rises, the force-bearing rod 13 on the front of the crank 5 will contact the compression rod 12 and be pushed, causing the crank 5 to swing around the pin. The swing of the crank 5 drives the limiting wheel 6 to move outward. The limiting wheel 6 gradually clamps the contact between itself and the display screen body 3. At this time, the display screen body 3 is fixed by the limiting wheel 6, completing the fixed connection of the display screen body 3. During the upward movement of the support frame 2, the limiting wheel at the bottom of the support frame 2... Position plate 15 will also move accordingly. The limiting plate 15 passes through the support frame 2 and extends to both sides of the display screen body 3, further ensuring the stability of the display screen during the adjustment process. The slide rod 16 on the inner side of the limiting plate 15 is slidably connected to the crank 5, ensuring that the movement of the limiting plate 15 is synchronized with the swing of the crank 5. After installation, the rotating wheel 11 is rotated in the opposite direction, and the screw 9 drives the lifting plate 10 and the support frame 2 to descend. The crank 5 swings in the opposite direction under the action of the pressing rod 12, and the limiting wheel 6 disengages from the display screen body 3, thereby the support frame 2 descends and completes the separation.

[0044] In summary, this display screen uses a movable mounting bracket. During the ascent of the support frame 2, the crank 5 and limiting wheels 6 limit the movement of the display screen body 3, significantly improving the connection efficiency of the display screen body 3 and solving the problems of existing mounting brackets having a simple structure and being difficult to disassemble. Through this special design, the display screen is made easier to install and disassemble, improving separation efficiency.
