Description

Technical Field

[0001] The utility model relates to the technical field of display screen locking structures, in particular to a locking structure of a combined LED large screen. Background Art

[0002] The existing large LED screen is generally composed of multiple small LED screens. The existing small LED screens are mainly fixed to the frame by screws. Due to the large number of screws required, the installation of the small LED screen is not convenient, and it is also inconvenient to disassemble, which reduces the installation and disassembly efficiency of the large LED screen. In addition, the existing large LED screen does not have a buffering function. When an external object hits the display screen, it is easy to cause the display screen to be black, broken, or damaged due to the lack of buffering. Therefore, a locking structure of a combined large LED screen is proposed to solve the above problems. Utility Model Content

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1-5 A locking structure for a combined LED large screen includes a display screen 1 and a mounting frame 3. A plug-in shaft 8 is fixedly connected to the center of the back of the display screen 1. A curved locking disc 7 is fixedly connected to the surface of the plug-in shaft 8. A rubber cover 2 is fixedly connected to the back of the display screen 1. A sealing groove 301 is provided at the top of the side wall of the mounting frame 3 to connect with the rubber cover 2.

[0021] It should be noted that: the sealing function of the seams between adjacent display screens 1 can be achieved to prevent dust and water from penetrating and affecting the internal electronic components of the display screen 1;

[0022] When the display screen 1 is hit by an external force, the rubber cover 2 will be deformed. The rubber cover 2 is elastic and can play a certain buffering role.

[0023] A socket is provided at the center of the mounting frame 3, and the bottom end of the mounting frame 3 is fixedly connected to the limiting column 4 at the socket. The side wall of the limiting column 4 is provided with a circumferentially distributed sliding opening, and the side wall of the limiting column 4 is fixedly connected to the outer shell 5 at the sliding opening. A locking assembly is provided on the inner side of the outer shell 5, and the locking assembly includes an arc-surface locking block 6 slidably connected to the inner side of the sliding opening, a connecting plate fixedly connected to one end of the arc-surface locking block 6, and a magnetic block 9 fixedly connected to the connecting plate. A locking spring 11 is fixedly connected between the connecting plate and the side wall of the limiting column 4, and the arc surfaces of the arc-surface locking block 6 and the arc-surface locking disc 7 are arranged facing each other.

[0024] It should be noted that: by inserting the insertion shaft 8 into the limiting cylinder 4, the arc-surface locking disc 7 will push the arc-surface locking block 6, causing it to retract into the inner side of the housing 5. When the arc-surface locking disc 7 is separated from the arc-surface locking block 6, under the action of the locking spring 11, the arc-surface locking block 6 is stuck between the arc-surface locking discs 7, realizing the limiting function of the insertion shaft 8, and then realizing the installation function of the display screen 1. No screws are required, which is convenient for installation and improves the assembly efficiency of the large display screen 1.

[0025] It is worth noting that when the display screen 1 is hit, the arc-surface locking disc 7 will push the arc-surface locking block 6 , and under the elastic force of the locking spring 11 , it plays a certain buffering role, thereby reducing the impact of the impact force on the display screen 1 .

[0026] A liquid storage box 10 is fixedly connected to the side wall of the housing 5 , and the interior of the liquid storage box 10 is filled with magnetic fluid.

[0027] It should be noted that: when the lock needs to be released, a magnet can be brought close to the display screen 1. Under the action of the magnetic field of the magnet, the magnetic fluid becomes magnetic, which can magnetically attract the magnetic block 9, thereby driving the arc surface locking block 6 to move, separating it from the arc surface locking disc 7 and retracting it to the inside of the sliding mouth, and then the insertion shaft 8 can be pulled out from the inside of the limiting column 4 to realize the dismantling function of the display screen 1.

[0028] There are multiple installation frames 3, and the multiple installation frames 3 are fixed together to form a complete installation rack.

[0029] When the present invention is in use, by inserting the insertion shaft 8 into the limiting cylinder 4, the arc surface locking disc 7 will push the arc surface locking block 6 to retract it into the inner side of the shell 5. When the arc surface locking disc 7 is separated from the arc surface locking block 6, under the action of the locking spring 11, the arc surface locking block 6 is stuck between the arc surface locking discs 7, realizing the limiting function of the insertion shaft 8, and then realizing the installation function of the display screen 1. No screws are required, which is convenient for installation and improves the assembly efficiency of the large display screen 1.

[0030] When the display screen 1 is hit by an external force, the rubber cover 2 will be deformed. The rubber cover 2 is elastic and can play a certain buffering role.

[0031] At the same time, the display screen 1 drives the arc surface locking disc 7 to move downward through the insertion shaft 8, thereby pushing the arc surface locking block 6, which further plays a buffering role under the elastic force of the locking spring 11, reducing the impact of the impact force on the display screen 1.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
