[0019] As Figures 1 to 3As shown, the embodiment of the utility model preferably provides a quick-install LED display screen, including a mounting base 1 and an LED light board 2, wherein the LED light board 2 is arranged on the front side of the mounting base 1, and the front side of the LED light board 2 is hooked with LED lamp beads 3, and the rear side of the LED light board 2 is provided with a connecting column 4, and a card block 5 is provided in the connecting column 4 which can move up and down relative to it, and a concave hole 6 which can cooperate with the connecting column 4 is provided on one side of the mounting base 1, and a card slot 7 which can cooperate with the card block 5 is provided on the upper side of the concave hole 6, and a top frame 8 which can move up and down on the rear side of the mounting base 1 is provided, and a fastening screw 9 which can tightly resist one side of the top frame 8 is threadedly inserted on one side of the mounting base 1, and the top frame 8 is in contact with the card block 5 so that the card block 5 remains in a connected state embedded in the card slot 7.

[0020] Specifically, the pre-positioning cooperation between the LED light board and the mounting base is achieved by correspondingly inserting the connecting pins on one side of the LED light board into the recessed holes of the mounting base, and then the fastening screws are screwed to move the fastening screw threads and abut against the top frame. The top frame moves relative to the mounting base and movably abuts against the card block, so that the card block remains in a connected state embedded in the card slot, thereby achieving complete fixation between the LED light board and the mounting base. The user can install and disassemble the mounting base and the LED light board by loosening and tightening a screw, which saves time and effort, and has relatively high assembly efficiency, meeting mass production needs.

[0021] Furthermore, the card block 5 is located on a side close to the LED light board 2 and is a first guide bevel 10, and the card slot 7 is located on a side close to the LED light board 2 and is a second guide bevel 11 that can match the first guide bevel 10. Specifically, when the card block is inserted into the card slot by the top frame, the first guide bevel of the card block is pressed against the second guide bevel of the card slot, so that the LED light board and the mounting base maintain a tightly fitting splicing state.

[0022] Furthermore, there are four connecting pins 4, which are distributed at the four corners of the LED lamp board 2. The four-corner connection effectively enhances the firmness of the structure.

[0023] Furthermore, the concave hole 6 has a downward opening, through which the outer shape is formed into a major arc shape, and the top frame 8 is movably arranged at the opening of the concave hole 6 and abuts against the card block 5. Specifically, the pre-positioned connection between the LED light board and the mounting base is realized by inserting the connecting column into the concave hole in a major arc shape, and the top frame can be subjected to force and movably pressed against the card block through the major arc opening of the concave hole, which can cause the card block to move upward relative to the connecting column, and maintain the connection state of the card block being inserted into the card slot in the concave hole.

[0024] Further, a first magnetic body (not labeled in the figure) is provided on the front side of the mounting base 1, and a second magnetic body 13 capable of magnetic attraction cooperation with the first magnetic body (not labeled in the figure) is provided on the rear side of the LED lamp board 2. Specifically, the first magnetic body of the mounting base and the second magnetic body of the LED lamp board are magnetically attracted and cooperated to achieve pre-positioning installation between the LED lamp board and the mounting base.

[0025] Further, the outer shape of the top frame 8 is annular, and top rods 14 capable of abutting against the clamping blocks 5 are provided at its four corners. Specifically, the top rods of the top frame pass through the major arc opening of the concave hole and abut against the clamping blocks, so as to realize the upward movement of the clamping blocks relative to the connecting plug posts.

[0026] Further, a through hole 15 is provided through the upper side of the connecting plug post 4. The cross section of the through hole 15 is T-shaped. The clamping block 5 is T-shaped and is movably arranged up and down in the through hole 15. The clamping block 5 is magnetically attracted in the through hole 15. Furthermore, when the fastening screw becomes loose, the clamping block can be quickly separated from the clamping groove by the acting force of magnetic attraction of the magnet and reset and placed in the through hole again.

[0027] Further, a first limiting block 16 and a second limiting block 17 are horizontally and spaced apart on the rear side of the mounting base 1. A limiting cover plate 18 is detachably connected between the first limiting block 16 and the second limiting block 17. The limiting cover plate 18 and the first limiting block 16 and the second limiting block 17 form a guiding hole in combination. The top frame 8 is movably arranged up and down in the guiding hole. The user can install and disassemble the top frame by disassembling the limiting cover plate.
