[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0022] The following describes an embodiment of the present invention based on its overall structure.

[0023] An installation size adjustment structure, such as Figure 1-Figure 3As shown, it includes an adjustment mechanism 1, which includes a bidirectional screw 101, a threaded plate 102, a limit plate 103, a horizontal plate 104, a limit column 105, a mounting plate 106 and a rotary handle 107. The threaded plate 102 is threadedly connected to the outer surface of the bidirectional screw 101. The two threaded plates 102 are both provided with a limit plate 103 on one side away from each other. The front end of the limit plate 103 is movably connected to the horizontal plate 104. The threaded plate 102 and the horizontal plate 104 are connected in a fixed manner. A mounting plate 106 is provided at the front end, a limiting groove is provided inside the limiting plate 103, and the limiting groove is arranged obliquely, a limiting column 105 is provided at the rear end of the transverse plate 104, and the transverse plate 104 and the limiting plate 103 form a sliding structure through the limiting column 105 and the limiting groove. A rotary handle 107 is provided at one end of the bidirectional screw rod 101, and the rotary handle 107 is composed of a disc and a cylinder. One end of the bidirectional screw rod 101 is rotatably connected to the mounting box 202 through a bearing;

[0024] See Figure 1-Figure 3 It can be seen that since the bidirectional screw rod 101 is threadedly connected to the threaded plate 102, and the threaded plate 102 is slidably connected to the installation box 202 through the limit rod 4 and the limit hole 3, the two threaded plates 102 can be moved in opposite directions in the horizontal direction by rotating the handle 107 and the bidirectional screw rod 101. Since a limit groove is provided in the limit plate 103, and the horizontal plate 104 is slidably connected to the limit plate 103 through the limit column 105 and the limit groove, the two horizontal plates 104 can be moved in opposite directions in the vertical direction, thereby realizing the adjustment of the distance between multiple groups of installation plates 106, and then the installation size of the LED display screen mounting frame can be adjusted according to actual needs, thereby improving the flexibility and extensiveness of use and ensuring stability during use.

[0025] See Figure 1 and Figure 2 It can be seen that the threaded plate 102 has symmetrically opened limiting holes 3 inside, and the limiting rod 4 is penetrated through the inner side of the limiting hole 3. The threaded plate 102 and the limiting rod 4 form a sliding structure through the limiting hole 3. The inner surface of the installation box 202 is welded to the limiting rod 4, which can support and limit the threaded plate 102, so as to prevent the threaded plate 102 from being offset during the sliding process.

[0026] See Figure 1-Figure 3It can be seen that a positioning mechanism 5 is provided on the outside of the bidirectional screw rod 101, and the positioning mechanism 5 is composed of a gear 501, a tooth plate 502, a lifting plate 503, a support plate 504 and a support spring 505. The lifting plate 503 is slidably connected to the inside of the support plate 504, and a support spring 505 constituting an elastic structure is provided between the lifting plate 503 and the support plate 504. One end of the lifting plate 503 is provided with a tooth plate 502, and the outer surface of the bidirectional screw rod 101 is sleeved with a gear 501 constituting a snap-fit ​​structure with the tooth plate 502. The tooth plate 502 is configured as an arc-shaped structure, and the outer surface of the mounting box 202 is welded to one end of the support plate 504;

[0027] See Figure 3 It can be seen that since the lifting plate 503 and the support plate 504 are elastically connected by the support spring 505, the lifting plate 503 is released after the installation size adjustment is completed, so that the lifting plate 503 and the tooth plate 502 are reset under the action of the support spring 505, and the tooth plate 502 is engaged with the gear 501, thereby locking the bidirectional screw rod 101 to prevent it from rotating, thereby ensuring the stability of the installation after the adjustment is completed.

[0028] An LED display screen mounting frame, such as Figure 1 and Figure 4 As shown, it includes a mounting frame body 2, which includes a base 201 and a mounting box 202. The mounting box 202 is installed at the top of the inner side of the base 201 to fix and support the LED display screen to ensure the stability and safety of the LED display screen.

[0029] The working principle of the present invention is as follows: when in use, the display screen is located inside the installation box 202, and then the two threaded plates 102 can be moved in opposite directions in the horizontal direction by rotating the handle 107 and the bidirectional screw rod 101. In this process, the two horizontal plates 104 can be moved in opposite directions in the vertical direction under the action of the limit column 105 and the limit plate 103, so that multiple groups of mounting plates 106 are simultaneously close to the display screen and clamped around the display screen, thereby enabling the installation of display screens of different sizes. At this time, the lifting plate 503 is released, so that it is reset under the action of the support spring 505 and the tooth plate 502 is clamped with the gear 501, thereby locking the bidirectional screw rod 101 to prevent it from rotating.
