[0002] LED display screen uses light-emitting diodes as light sources and is composed of many small LED modules. It provides high-brightness display effects and can be clearly seen even in direct sunlight. It can be combined into various sizes and shapes. It is a comprehensive product that integrates electronic technology, computer technology, information technology, and optoelectronic technology. It mainly assembles several small LED screens and connects the images in series to form a large screen, which can be fully used for multimedia information release. In recent years, LED display technology has developed rapidly, and LED display screens have been widely used in many occasions, especially important occasions such as government agencies, live broadcasts or large-scale performances.

[0003] When using existing large LED screens, multiple screws are usually used to fix small screens on a steel structure bracket, and workers need to use tools to tighten the screws separately, which is cumbersome to install. After being used outdoors for a period of time, the screws are prone to rust, increasing the difficulty of disassembly. At the same time, gaps are easily generated between the small screens, affecting the image display quality. In view of this, the present application proposes an easy-to-assemble large LED screen. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 An easy-to-assemble LED large screen includes a display screen 1 and a base 2, the display screen 1 and the base 2 are fixedly connected by multiple bolts, a plurality of heat dissipation holes 3 are opened on the side wall of the base 2, and the heat generated can be dissipated in time when the large screen is in use, a slot 4 is opened on one side of the base 2, and a boss 5 is fixedly connected to the other side of the base 2, the length of the slot 4 is greater than the length of the boss 5, the width of the slot 4 is equal to the width of the boss 5, the side wall of the boss 5 is tightly fitted with the inner wall of the slot 4, and the gap generated during assembly can be reduced.

[0021] A groove 6 is provided at the top of the base 2, and two rotating shafts 7 are symmetrically arranged in the groove 6. The two rotating shafts 7 are respectively fixedly connected with mounting plates 9. One end of the two rotating shafts 7 is rotatably connected to the inner wall of the groove 6, and the other ends of the two rotating shafts 7 extend to the outside of the base 2. Furthermore, when the connecting rod 10 rotates, the rotating shaft 7 inside the groove 6 will be driven to rotate synchronously, and the abutting part of the connecting rod 10 and the movable rod 8 will synchronously play a limiting role, thereby completing the fixation of the small screen.

[0022] Connecting rods 10 are respectively installed on the corresponding side walls of the two assembly plates 9 through axle seats, and springs 11 are installed between the corresponding assembly plates 9 and the connecting rods 10. The connecting rods 10 are divided into a pressing part, a supporting part and abutting part. The side walls corresponding to the supporting part are fixedly connected to the upper end of the spring 11, and the lower end of the spring 11 is fixedly connected to the side walls of the assembly plate 9. It should be noted that the axle seat is T-shaped composed of two connecting rods, which limit the synchronous rotation of the connecting rod 10 and the assembly plate 9 in the axial direction parallel to the base 2. In the corresponding vertical axial direction, the connecting rod 10 can rotate relative to the assembly plate 9.

[0023] Two limiting grooves 12 are symmetrically provided on the bottom side wall of the base 2, and the positions of the two limiting grooves 12 correspond to the positions of the abutting parts of the connecting rod 10. The abutting parts of the connecting rod 10 move into the limiting grooves 12, and the protruding side walls of the abutting parts are fully fitted with the inner walls of the limiting grooves 12, which can provide a better fixing effect.

[0024] The bottom of the base 2 is fixedly connected with a second support plate 14 and two first support plates 13, and the second support plate 14 is arranged between the two first support plates 13. The corresponding two side walls of the second support plate 14 are respectively provided with arc grooves 15. The arc groove 15 and the movable rod 8 are arranged on the same axis, and the depth of the arc groove 15 corresponds to the length of the movable rod 8.

[0025] When the utility model is used, it is assembled according to the size of the required large screen. When splicing the left and right sides, the boss 5 of one of the small screens slides into the slot 4 from top to bottom, and the side wall of the boss 5 contacts the inner wall of the slot 4 to ensure that the small screens are tightly connected. When splicing up and down, the connecting rods 10 on both sides are kept horizontal, and the first support plate 13 and the second support plate 14 at the bottom of one of the small screens are inserted into the groove 6. At this time, the bottom of the connecting rod 10 is pressed and rotated. When the upper end of the connecting rod 10 corresponds to the position of the limit groove 12, it is released. The pressing part of the connecting rod 10, under the elastic force of the spring 11, pulls the top of the connecting rod 10 to abut against the inner wall of the limiting groove 12. The assembly plate 9 will drive the rotating shaft 7 to rotate while the connecting rod 10 rotates. The movable rod 8 fixedly connected to the rotating shaft 7 will move into the arc groove 15, further fixing the second support plate 14 to improve the stability of the connection. When disassembling, press the bottom of the connecting rod 10 and rotate it to both sides. The abutting part of the connecting rod 10 is separated from the limiting groove 12, and the movable rod 8 is separated from the arc groove 15 at the same time, so that the two small screens can be removed more conveniently.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
