[0026] The surface of the screen upper end positioning seat 15 is provided with an upper groove 111, and the inner side of the upper groove 111 is adhesively connected with a silica gel pad 16 through resin. The upper groove 111 is the same as the lower groove 12, and is a shallow groove structure. When the LED screen upper end is positioned, the space occupied by the screen is reduced, or the screen part of the LED can be directly fitted and positioned. The silica gel pad 16 can play a buffering effect when the screen upper end positioning seat 15 is pressed downward to extrude and position the LED screen cooperating with the screen lower end positioning seat 11.

[0027] The upper end of the screen lower end positioning seat 11 is fixed with a bearing 17, the inner ring wall of the bearing 17 is interference-fitted with a threaded rod 18, the upper end of the threaded rod 18 is fixed with a twist knob 110, the surface of the threaded rod 18 is threadedly connected with a threaded sleeve I 19, and the outer ring wall of the threaded sleeve I 19 is fixedly assembled with the surface of the screen upper end positioning seat 15 through a support. When the LED screen needs to be positioned, the LED screen is first placed into the screen lower end positioning seat 11, then the threaded rod 18 is rotated by twisting the twist knob 110, so that it stably rotates based on the bearing 17, thereby making the threaded sleeve I 19 move, and the screen upper end positioning seat 15 can stably move up and down through the sliding of the limiting rod 14 on the surface of the limiting sleeve 13, so that the LED screen can be clamped and positioned in the up-down position by cooperating with the screen lower end positioning seat 11.

[0028] It should be further explained that the surface of the screen lower end positioning seat 11 is fixedly penetrated with a plurality of threaded sleeves II 2, the inner side of the threaded sleeves II 2 is threadedly connected with a threaded knob 21, and the threaded knob 21 can be moved relative to the threaded sleeves II 2 to realize the expansion and contraction adjustment of the extrusion pad 22.

[0029] It should be further explained that one end of the threaded knob 21 close to the lower groove 12 is fixed with an extrusion pad 22, the extrusion pad 22 is made of rubber material, and the extrusion pad 22 can be arranged to fit the back of the LED screen, so that the front and back of the LED screen can be positioned by cooperating with the lower groove 12, and the front and back of the LED screen can be prevented from being inclined after being clamped by the upper and lower positioning seats.

[0030] It should be further explained that a plurality of mounting plates 3 are fixedly distributed on both sides of the base 1, the mounting plates 3 are symmetrically arranged two by two along the two sides, the lower end surface of the mounting plate 3 is on the same horizontal plane as the lower end surface of the base 1, and the mounting plate 3 can increase the front and back support area of the base 1, so that the LED screen will not be inclined and collapsed when placed on the ground.

[0031] It needs to be further explained that the surface of the mounting plate 3 is provided with a mounting hole one 31 penetrating through the inside thereof, and the inner wall of the mounting hole one 31 is a smooth surface or a threaded surface. The fixing of the base 1 to the ground can be realized by penetrating the mounting hole one 31 with a screw or a bolt.

[0032] It needs to be further explained that the mounting rack 4 is fixed to one side of the base 1, and the mounting rack 4 is arranged along the symmetrical distribution of the base 1. The mounting rack 4 is of an L-shaped structure, and the lower end surface of the mounting rack 4 is located on the same horizontal plane as the lower end surface of the base 1. The mounting rack 4 of the L-shaped structure can better fit the wall surface, improve the contact area, and ensure the stable fixing of the base 1 with the LED screen to the wall surface.

[0033] It needs to be further explained that the surface of the mounting rack 4 is provided with a plurality of mounting holes two 41, which are arranged at equal intervals along the vertical position of the mounting rack 4. The plurality of mounting holes two 41 arranged at multiple positions can ensure that the mounting rack 4 with the base 1 has the effect of multi-point fixing when being installed on the wall surface.

[0034] Working mode: The present scheme is mainly realized through the cooperation of the screen lower end positioning seat 11 and the screen upper end positioning seat 15. The upper surface of the screen lower end positioning seat 11 is provided with a shallow lower groove 12 for supporting the bottom edge of the LED screen to avoid blocking the display area. The screen upper end positioning seat 15 is vertically moved through the sliding cooperation of the limiting rod 13 and the limiting sleeve 14. The inner side upper groove 111 of the screen upper end positioning seat 15 is fitted to the top of the screen, and the internal silica gel pad 16 provides buffer protection for the structure of the LED screen clamping and adjusting, which includes the driving part of the threaded rod 18 and the threaded sleeve one 19: when the rotating knob 110 is rotated and twisted, the threaded rod 18 rotates under the support of the bearing 17, drives the threaded sleeve one 19 to move the screen upper end positioning seat 15 up and down, so as to exert uniform pressure on the screen. The limiting rod 13 ensures the stability of movement and avoids deflection. This design realizes quick installation and height adaptation, and reduces mechanical damage to the screen through the shallow groove structure and flexible material.

[0035] In order to prevent the screen from shaking forward and backward after being clamped up and down, the threaded sleeve two 2 is fixed through the side wall of the screen lower end positioning seat 11, the internal screwing thread knob 21 is screwed, the end part is connected with the extrusion pad 22 made of rubber material, the extrusion pad 22 can be controlled to advance forward by rotating the threaded knob 21, until it is in close contact with the back of the screen. Combined with the limiting of the lower groove 12 to the front of the screen, a bidirectional clamping force is formed to eliminate the risk of longitudinal displacement of the screen. This structure is especially suitable for the installation of ultra-thin LED screens. Precise positioning is realized through multi-point fine adjustment to ensure that the screen remains vertically stable under the action of vibration or external force.

[0036] The anti-toppling design of the base comprises two parts: one is the extended support of the mounting plate 3, and the other is the wall fixing of the mounting frame 4. The mounting plate 3 is symmetrically distributed on both sides of the base 1, the bottom of which is flush with the base, so as to increase the grounding area, disperse the center of gravity pressure of the screen, prevent the front and back overturning, and support the screws or bolts through the mounting holes 31, and optionally ground anchor or weight block installation.

[0037] The above merely describes a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
