[0032] like Figures 1 to 3 As shown, an adjustable mounting bracket includes a support base 1;

[0033] A supporting portion 2, which is used to place external equipment 5;

[0034] An angle adjustment device 3, which is arranged on the support seat 1, and the angle adjustment device 3 is used to adjust the rotation angle of the supporting part 2;

[0035] A moving device 4, one end of which is connected to the angle adjustment device 3, and the other end of which is connected to the supporting portion 2, and the moving device 4 is used to drive the supporting portion 2 to move forward and backward and / or up and down.

[0036] This solution provides an angle-adjustable and retractable mounting bracket, which is used to mount control equipment or auxiliary equipment of a display screen, such as a speaker or control box of the display screen, etc. Of course, the mounting bracket can also be used to mount other equipment other than the display screen, such as a projector, etc.

[0037] Since the adjustable mounting bracket of the present solution includes an angle adjustment device 3 and a moving device 4, the vertical height and front-to-back distance can be freely adjusted, and the angle of the device can also be freely adjusted to meet different installation requirements of users, solving the problem of inconvenient adjustment and poor adaptability of traditional fixed brackets. In addition, the above-mentioned components are mainly fixed by bolts, which can achieve quick installation and disassembly, improve equipment installation efficiency, and reduce maintenance costs.

[0039] The angle adjustment device 3 includes a fixed frame 31 and a rotating frame 32. The rotating frame 32 is rotatably arranged on the fixed frame 31 through a rotating shaft 33. Since the moving device 4 and the supporting part 2 are both arranged on the rotating frame 32, the supporting part 2 can also be synchronously adjusted to a preset angle when the rotating frame 32 rotates. In the initial state, the rotating frame 32 is in a horizontal position, and the adjustment rod 34 is located at the initial position in the adjustment limit groove 321; when the angle needs to be adjusted, the rotating frame 32 is manually rotated, and the adjustment rod 34 moves in the adjustment limit groove 321. After the rotating frame 32 rotates to the desired position, the adjustment rod 34 is stuck in another position of the adjustment limit groove 321, so that the rotating frame 32 can be stably in the rotated state without moving.

The adjusting rod 34 and the rotating shaft 33 first pass through the first side wall of the fixed frame 31, then pass through the rotating frame 32, and then pass through the second side wall of the fixed frame 31 to achieve the connection between the two (the fixed frame 31 and the rotating frame 32), which can ensure that the rotation of the rotating frame 32 is smoother and the service life of the angle adjustment device 3 is longer.

[0043] Furthermore, a mounting channel 312 is provided on the rear side of the fixing frame 31, and at least one connecting portion 11 is provided on the supporting seat 1, and each connecting portion 11 is provided with a mounting hole 111, and the rotating rod 12 passes through the mounting hole 111 and the mounting channel 312 to realize the rotational connection between the fixing frame 31 and the supporting seat 1.

The first limiting hole 324 of the rotating frame 32 is matched with the first movable pin 4111 on the telescopic rod 411. When it is necessary to telescope forward and backward, the first movable pin 4111 is manually pressed inward to stretch the telescopic rod 411 to the corresponding first limiting hole 324. The first movable pin 4111 is no longer pressed. After the first movable pin 4111 is extended, it is limited and fixed, so that the mounting bracket can be quickly and freely telescoped to the required distance.

[0047] In addition, precise scale lines can be set on the outer wall surface of the rotating frame 32, so that the user can manually and accurately adjust the extension distance of the mounting bracket. Specifically, the extendable distance of the telescopic rod 411 can be set to 60 mm.
