Description

Technical Field

[0001] The utility model belongs to the technical field of screen splicing, and particularly relates to an LED screen that is easy to splice. Background Art

[0002] LED screen is a display technology that produces images and text by connecting LED (light emitting diode) chips to circuit boards and other electronic components. LED screens are usually composed of many small LED chips, which can be connected together through circuits to form a matrix. The screen can adjust the brightness of each pixel as needed to change the displayed content. Since LED screens are lighter, more durable and easier to transport than traditional rear projectors, they are often used in stage performances, concerts, exhibitions and other activities. In some special activities, larger screens are needed. Large screens are usually not convenient to transport and install, so multiple small screens need to be spliced ​​and used.

[0003] During use, some existing LED screens are usually spliced ​​by fixing multiple small screens in sequence on a specific mounting frame with screws. This splicing method does not allow installers to perform quick splicing, is time-consuming and labor-intensive, and is inconvenient for installers to operate. Utility Model Content

A fixed block 12 is arranged on one side of the moving block 11. The push rod 9 is sleeved with a third spring 13 on the outer side away from the protrusion 8, and a limiting block is fixed on one side of the third spring 13. 18.

[0027] Working principle: When the utility model is used, the user fixes the first connecting frame 2 and the second connecting frame 3 on one side of the screen body 1 respectively, and then splices the first connecting frame 2 and the second connecting frame 3, thereby driving the screen body 1 to be spliced. When the protrusion 8 slides in the second groove 16, one end of the protrusion 8 will push the block 7 to move upward, and the block 7 drives the limit rod 5 to move upward, so that the limit rod 5 moves inside the limit sleeve 4, and at the same time drives the first spring 6 to be squeezed. When the protrusion 8 moves to one side of the block 7, the block 7 is driven to rebound by the first spring 6, and at the same time the third spring 13 will also be in the third groove 17, the projection 8 is rebounded and limited by the push rod 9, so that the projection 8 is rebounded by the push rod 9, and then the projection 8 is fixed by the clamping block 7. During the movement of the projection 8, the first connecting frame 2 and the second connecting frame 3 are connected, so that the purpose of splicing the screen body 1 can be achieved. When it needs to be dismantled, the connecting rod 14 is pushed, and the connecting rod 14 drives the projection 8 to move through the push rod 9. At the same time, the push rod 9 drives the moving block 11 to move through the fixed block 12. When the moving block 11 moves to one side of the clamping block 7, the connecting rod 14 is pulled to drive the projection 8 to move through the push rod 9, and the moving block 11 passes through the limiting block 18 during the movement. The push rod 9 is limited, and the moving block 11 squeezes the second spring 10 until it fits with the projection 8. When it moves to one side of the clamping block 7, the moving block 11 rebounds through the second spring 10 to reset.
