[0034] In this embodiment, in order to achieve the effect of quickly installing LED screens 2 of different widths, a docking assembly 4 is designed. A telescopic rod 4-1 is arranged on the surface of the mounting frame 3, and a connecting seat 4-2 is installed between the telescopic rods 4-1. During installation, the telescopic rod 4-1 can be pulled out and can be telescopically matched according to the width of the inserted LED screen 2. The connecting seat 4-2 is provided with a round hole 4-3 for inserting the LED screen 2. Plug holes 4-4 are provided at both upper and lower ends of the surface of the connecting seat 4-2. An insert block 4-5 is arranged on the back of the LED screen 2. The insert block 4-5 is used to be inserted into the plug hole 4-4 and is located at the connecting seat 4-2. Grooves 4-7 are provided at both ends, and a card block 4-9 and a first spring 4-8 are connected inside the groove 4-7. A card slot 4-6 is provided at the bottom of the plug-in block 4-5. The card block 4-9 cooperates with the card slot 4-6 to limit the plug-in block 4-5, so that the plug-in block 4-5 cannot be pulled out after being inserted. In addition, a plurality of sleeve blocks 4-10 are provided on the back of the LED screen 2, and a reinforcement block 4-11 is provided on the side surface of the mounting frame 3. The reinforcement block 4-11 is used to drive the reinforcement block 4-11 to be inserted into the interior of the sleeve block 4-10 for further reinforcement when the telescopic rod 4-1 is recovered during the installation of the LED screen 2.

[0035] Furthermore, the telescopic connection assembly 5 includes an active cavity 5-1, which is opened in the base 1. A connecting rod 5-2 is fixedly connected to the side end face of the base 1.

A fixing column 5-4 is opened on the back of the base 1, and a locking frame 5-5 is rotatably connected to the surface of the other base 1. The locking frame 5-5 can be mounted on the fixing column 5-4, so that the two bases 1 cannot be extended, which can fix them during transportation to prevent them from falling off due to vibration.

[0037] Furthermore, the card slot 4-6 and the card block 4-9 are tooth-shaped structures.

[0038] In this embodiment, the toothed structure of the card slot 4-6 cooperates with the card block 4-9, so that the card block 4-9 can slide in and out of the card slot 4-6.

[0039] Furthermore, the cross section of the connecting rod 5 - 2 is a T-shaped structure, and the cross section of the connecting rod 5 - 2 is a rectangular structure.

[0040] In this embodiment, the T-shaped structure and the rectangular cross-section structure ensure that the connecting rod 5-2 will not rotate or fall off during the extension and retraction process.

[0043] When installation is required, open the lock frame 5-5, pull the base 1 outward, insert the LED screen 2 into the round hole 4-3 of the connecting seat 4-2, and insert the plug block 4-5 into the socket 4-4. When inserted, it will push the card block 4-9, and the card block 4-9 will retract into the groove 4-7 when squeezed, and be pushed out and snapped into the inside of the card slot 4-6 by the elastic force of the first spring 4-8. After snapping, it indicates that the installation is completed, release the base 1, and let the base 1 be pushed to reset by the elastic force of the second spring 5-3. When resetting, the reinforcement block 4-11 is inserted into the sleeve block 4-10.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
