[0001] The present application relates to the technical field of display screen brackets, and in particular to an adjustable wall-mounted liquid crystal bracket. Background Art

[0002] An LCD screen stand is a device specially designed to support and fix an LCD monitor, and is usually used in homes, offices, schools, and other places. An LCD screen stand can help users better adjust the height, angle, and position of the monitor for a more comfortable viewing experience. A wall mount is a bracket used to fix a monitor, TV, or other display device to a wall. It can help save space, provide a better viewing angle, and improve the aesthetics of your home or office environment.

[0003] For example, in the existing Chinese patent with publication number CN215259100U, a wall-mounted display screen mounting bracket is disclosed, which includes a back plate and a display screen fixing frame; a plurality of hooks are provided on the back plate; and a plurality of hanging holes matching with the hooks are provided on the display screen fixing frame. Through the above-mentioned prior art, the display screen can be mounted on the wall, simplifying the installation and removal steps of the display screen, which is convenient and quick; at the same time, the display screen can be kept at a certain distance from the wall, which is convenient for plugging and unplugging the connecting wires, and the overall structure is simple, cost-saving, and convenient for maintenance.

[0004] However, the above prior art has the following technical defects:

[0029] The following is combined with Figure 1-Figure 7 This application is described in further detail.

[0030] The embodiment of the present application discloses an adjustable wall-mounted LCD bracket, which can mount a LCD screen on a wall and can adjust and lock the LCD screen at multiple angles as required to provide an optimal viewing angle.

[0031] Reference Figures 1 to 3 As shown, the present application provides an adjustable wall-mounted LCD bracket, comprising a side wall back panel 1 and a bent connecting plate 11 integrally arranged on one side of the side wall back panel 1, and an assembly adjustment device 2 is provided on one side of the side wall back panel 1; when in use, the side wall back panel 1 is first installed on the wall, and then the LCD screen is installed through the assembly adjustment device 2. After installation, the LCD screen can be adjusted at multiple angles, and the adjusted angle can be locked to allow the LCD screen to maintain an optimal viewing angle.

[0032] The assembly adjustment device 2 includes an assembly rod seat 21 installed on one side of the side wall back plate 1, and an assembly connecting rod 22 is provided through the assembly rod seat 21. It should be noted that the assembly rod seat 21 is fixedly installed on one side of the side wall back plate 1, and the assembly connecting rod 22 and the assembly rod seat 21 are also fixedly arranged; two rectangular mounting seats 23 are symmetrically sleeved on the assembly connecting rod 22, and an assembly outer plate 24 is installed on the side of the two rectangular mounting seats 23 away from the side wall back plate 1, and the assembly outer plate 24 and the two rectangular mounting seats 23 are fixedly connected; the assembly outer plate 24 can rotate at a certain angle when driven. A regulating mechanism 3 is provided on the side of the assembly outer plate 24 facing the side wall back plate 1. It is used to lock the position of the assembly outer plate 24.

[0033] The side wall back panel 1 is installed on the wall, and the LCD screen is installed on one side of the assembly outer panel 24. When the angle of the LCD screen needs to be adjusted, the rotation lock of the assembly outer panel 24 is first released through the regulating mechanism 3, and then the assembly outer panel 24 is rotated to the required angle, and then the rotation of the assembly outer panel 24 is locked again through the regulating mechanism 3, so that the assembly outer panel 24 can maintain the position after rotation adjustment.

[0034] Reference Figure 4 and Figure 5 As shown, specifically, the regulating mechanism 3 includes a limiting round rod 31, a limiting block 32 and a locking assembly 4; the two limiting round rods 31 are symmetrically installed on the side of the assembly outer plate 24 facing the side wall back plate 1, the limiting block 32 is limited and slidably arranged on the two limiting round rods 31, and the limiting block 32 is symmetrically provided with limiting slots 321 adapted to the two limiting round rods 31; under the restriction of the two limiting round rods 31, the limiting block 32 is subjected to force to slide up and down.

[0035] A tension spring 33 connected to the restriction rod 31 is arranged inside the restriction block 32. A hook hole 322 for installing the tension spring 33 is provided at the bottom of the restriction block 32. One end of the tension spring 33 is connected to the restriction rod 31, and the other end is hooked at the hook hole 322 at the bottom of the restriction block 32. Since the two restriction rods 31 are fixedly connected to the assembly outer plate 24, the restriction block 32 always has an upward driving force under the action of the tension spring 33; an adjustment rope 34 is arranged at the lower side of the restriction block 32, and the locking assembly 4 is arranged on the assembly outer plate 24 between the restriction block 32 and the two rectangular mounting seats 23.

[0036] In the initial state, the assembly outer plate 24 and the side wall back plate 1 are parallel to each other. At this time, under the action of the tension spring 33, the upper end of the limiting block 32 will contact the bent connecting plate 11, thereby achieving the effect of locking the assembly outer plate 24 on one side of the side wall back plate 1. At this time, the assembly outer plate 24 cannot rotate. When it is necessary to release the lock to adjust the rotation angle of the assembly outer plate 24, it is only necessary to pull the adjustment rope 34 downward to drive the limiting block 32 downward so that the upper end of the limiting block 32 no longer conflicts with the bent connecting plate 11.

[0037] Replay Figure 4 As shown, in order to prevent the limiting block 32 and the tension spring 33 from being separated from the two limiting round rods 31 when the assembly outer plate 24 rotates, a limiting clamping plate 36 for limiting the limiting block 32 is installed on the side of the assembly outer plate 24 facing the side wall back plate 1 through two cross bolts 35. Under the action of the limiting clamping plate 36, the limiting block 32 can only be displaced upward or downward under force; and ensure that after the assembly outer plate 24 rotates to a certain angle, the limiting block 32 will not be separated from the two limiting round rods 31 and fall off.

[0038] Reference Figure 6 and Figure 7 As shown, since it is necessary to lock the angle of the assembly outer plate 24 after rotation and adjustment, the locking assembly 4 includes a locking gear 41, an assembly cross bar 42 and a linkage member 5; the two locking gears 41 are arranged at both ends of the assembly connecting rod 22 through an internal shaft 43, and the two locking gears 41 and the assembly connecting rod 22 are fixedly connected; the assembly cross bar 42 is installed on the side of the assembly outer plate 24 facing the side wall back plate 1, and is located below the two locking gears 41, and the linkage member 5 is arranged on the assembly cross bar 42 and the limiting block 32, which is used to connect with the limiting block 32 and lock the position of the assembly outer plate 24 after rotation through the two locking gears 41.

[0039] Reference Figure 6 and Figure 7As shown, in order to facilitate synchronous control of the rotation and locking of the two locking gears 41, the linkage member 5 includes a T-shaped slider 51 symmetrically limited and slidably arranged on the assembly cross bar 42, and the assembly cross bar 42 is symmetrically provided with a T-shaped slot 421 for the T-shaped slider 51 to be installed, and the upper ends of the two T-shaped sliders 51 are both installed with a locking tooth block 52 adapted to the locking gear 41. The assembly cross bar 42 is fixedly connected to the assembly outer plate 24. When the T-shaped slider 51 is forced to move upward so that the locking tooth block 52 abuts and is stuck on the locking gear 41, the assembly outer plate 24 cannot rotate at this time.

[0040] Continue to refer to Figure 6 and Figure 7 As shown, a U-shaped connecting rod 53 is clamped at the bottom of the two T-shaped sliders 51, and the U-shaped connecting rod 53 is connected to the limiting block 32 through a middle connecting rod 54. In the initial state, the assembly outer plate 24 and the side wall back plate 1 are both vertical and parallel to each other. At this time, the upper end of the limiting block 32 is tightly clamped on the bent connecting plate 11 under the action of the tension spring 33, and the setting of the middle connecting rod 54 and the U-shaped connecting rod 53 makes the T-shaped slider 51 at this time at the highest position, and the locking tooth block 52 is clamped on the locking gear 41; under the double locking, the assembly outer plate 24 cannot be rotated to adjust the angle.

[0041] When the angle of the LCD screen needs to be adjusted, the adjustment rope 34 is pulled downward to drive the limiting block 32 to move downward and no longer interfere with the bent connecting plate 11. At the same time, driven by the middle connecting rod 54 and the U-shaped connecting rod 53, the two T-shaped sliders 51 will also move downward, so that the locking tooth block 52 is separated from the locking gear 41, thereby releasing the rotation lock on the assembly outer plate 24. After rotating the assembly outer panel 24 to adjust the LCD screen to a certain angle and then releasing the adjustment rope 34, the limiting block 32 moves up and resets under the action of the tension spring 33. Although the upper end of the limiting block 32 cannot contact the bent connecting plate 11 at this time, the upward movement of the limiting block 32 drives the middle connecting rod 54 and the U-shaped connecting rod 53 to move up and reset synchronously, so that the locking tooth block 52 can contact and clamp on the locking gear 41 again, so that the assembly outer panel 24 can maintain a tilted state and cannot rotate under the meshing of the locking tooth block 52 and the locking gear 41, thereby achieving the effect of locking the position of the assembly outer panel 24 after the angle adjustment.

[0042] The implementation principle of this embodiment is:

[0043] (1) Equipment installation: First, install the side wall back panel 1 on the wall at the designated location, and then install the LCD screen on one side of the assembly outer panel 24.

[0044] (2) Status locking: After the LCD screen is installed, the assembly outer panel 24 and the side wall back panel 1 are in a vertical and parallel state, the upper end of the limiting block 32 is tightly clamped on the bent connecting plate 11, and the locking tooth block 52 is abutted and clamped on the locking gear 41, so as to achieve the purpose of double locking of the assembly outer panel 24.

[0045] (3) Angle adjustment: When angle adjustment is required, the adjustment rope 34 is pulled down to drive the limiting block 32 to move downward. The two T-shaped sliders 51 are moved downward synchronously through the drive of the middle connecting rod 54 and the U-shaped connecting rod 53, so that the locking tooth block 52 is separated from the locking gear 41 to release the rotation lock of the assembly outer panel 24. The assembly outer panel 24 with the LCD screen installed can be rotated to a certain angle.

[0046] (4) Position locking: After the angle adjustment is completed, the adjustment rope 34 is released, and the limiting block 32 is moved up and reset under the action of the tension spring 33, and the middle connecting rod 54 and the U-shaped connecting rod 53 are driven to move up synchronously, so that the locking tooth block 52 is again abutted and clamped on the locking gear 41, so as to lock the position of the assembled outer panel 24 after the angle adjustment.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
