[0002] LED display screen is a display method that controls semiconductor light emitting diodes. It is roughly composed of many usually red light emitting diodes, and the characters are displayed by the on and off of the lights. For large LED display screens, multiple screens are generally used for easy installation and transportation.

[0003] In the prior art, when assembling multiple screens, the screens need to be docked one by one for installation, the screens are mounted on a frame by magnets, and then the screens are connected with data cables. Although the display screen installed in this way can be used normally, the screen is easily dropped from the frame when subjected to external force because the screen is only mounted by magnets, causing damage to the screen. Therefore, a quick-connect LED display screen is proposed to solve the above problem. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 5The utility model provides an embodiment: a quick-connect LED display screen, including a base 1, a frame 2 is fixedly connected to the outer edge of the top of the base 1, a plurality of inner shells 3 are arranged in the middle of the frame 2, a screen 4 is fixedly connected to the top of the inner shell 3, and the screen 4 is the main body of the LED display screen, which is the prior art and will not be described in detail here. The plurality of inner shells 3 are connected by a splicing assembly. After the inner shells 3 are connected by the splicing assembly, the screen 4 can be made into a whole, so as to ensure the stability of the display screen structure to avoid the display screen from being scattered when it is hit by an external impact. The splicing assembly includes a protrusion 5, which is fixedly connected to the outer side of the inner shell 3, and a slot 7 is provided on the other side of the inner shell 3. The shape of the slot 7 is adapted to the protrusion 5, and the protrusion 5 can pass through the middle of the slot 7. An annular groove 8 is provided on the inner side of the inner shell 3. After the protrusion 5 passes through the middle of the slot 7, it can be rotated along the annular groove 8. A snap-in groove 9 is provided on the inner wall of the annular groove 8, and a snap-in ball 6 is fixedly connected to the inner side of the protrusion 5. The snap-in ball 6 and the snap-in groove 9 are snap-into each other. When the protrusion 5 rotates along the annular groove 8, the snap-in ball 6 can be driven to rotate together. Then, when the snap-in ball 6 reaches the position of the snap-in groove 9, it rebounds under the action of its own elasticity and snaps in with the snap-in groove 9, thereby assembling the two inner shells 3 and the screen 4, so that the screen 4 is connected as a whole to ensure the stability between the structures.

[0031] Reference Figure 2-Figure 3 The top of the base 1 is fixedly connected with a mounting seat 10, and a clamping rod 11 is rotatably connected with the middle part of the mounting seat 10. A clamping beam 12 is fixedly connected to the outside of the inner shell 3, and the clamping rod 11 and the clamping beam 12 are overlapped. A spring 13 is arranged between the mounting seat 10 and the clamping rod 11. After the inner shell 3 is inserted between the two clamping rods 11, the clamping rod 11 will first be affected by the clamping beam 12 and rotate. When the clamping beam 12 reaches the angle position of the clamping rod 11, the clamping rod 11 can be rotated under the action of the spring 13. At this time, the angle of the clamping rod 11 will be hooked with the clamping beam 12 to complete the restriction of the position of the clamping beam 12. One end of the spring 13 is fixedly connected to the inside of the mounting seat 10, and the other end of the spring 13 contacts the outer side wall of the clamping rod 11. The purpose is to reduce the bending of the spring 13 while ensuring that the clamping rod 11 can be reset, thereby extending the service life of the spring 13. A push rod 14 is slidably connected to the middle of the mounting seat 10, and the side of the push rod 14 close to the clamping rod 11 is located below the rotating shaft of the clamping rod 11; when the inner shell 3 needs to be disassembled, it is only necessary to press the push rod 14 inward, and the movement of the push rod 14 will act on the bottom end of the clamping rod 11, so that the clamping rod 11 rotates along the rotating shaft. At this time, the corner at the top of the clamping rod 11 will fall off from the top of the clamping beam 12, and the inner shell 3 can be removed from between the clamping rods 11.

[0032] Reference Figure 2-Figure 4A through hole 15 is provided on the outside of the frame 2, and a push rod 14 is slidably connected to the middle of the through hole 15. The push rod 14 can be operated from the outside of the frame 2 through the through hole 15, so as to ensure the rapid disassembly of the inner shell 3 as a whole; a vent 17 is provided on the outside of the frame 2, and a cooling fan 16 is fixedly connected to the inside of the frame 2, and the direction of the cooling fan 16 is adapted to the position of the vent 17; the cooling fan 16 can increase the air flow rate inside the frame 2, so that the heat generated by the screen 4 when working can be discharged from the vent 17.

[0033] Working principle: When in use, insert the protrusion 5 on the outside of one of the inner shells 3 from the slot 7 into the inside of the other inner shell 3, and then rotate one of the inner shells 3. At this time, the protrusion 5 will rotate along the annular groove 8. When the clamping ball 6 reaches the clamping groove 9, it can enter the middle of the clamping groove 9 under the action of its own elasticity and complete the clamping with the clamping groove 9, so as to realize the assembly between the two inner shells 3. Then put the inner shell 3 in from the middle of the two mounting seats 10, and align the clamping beam 12 with the upper oblique opening of the clamping rod 11, and then press the inner shell 3 downward. When the clamping beam 12 reaches the inner corner of the clamping rod 11 along the top oblique opening of the clamping rod 11, the spring 13 rebounds due to the disappearance of external force. At this time, the clamping rod 11 can hook the clamping beam 12 to complete the connection between the inner shell 3 and the base 1. The operation is simple and the installation efficiency is greatly improved.

[0034] Secondly, when the inner shell 3 and the screen 4 need to be disassembled, it is only necessary to push the push rod 14 from the outside of the frame 2, and the push rod 14 can act on the bottom end of the card rod 11. At this time, the card rod 11 will rotate along the rotating shaft, and the top end of the card rod 11 will fall off from the outside of the clamping beam 12. At this time, the inner shell 3 and the screen 4 can be disassembled, and the operation is very simple and convenient.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
