The invention discloses a self-locking mechanism, which comprises a fixed frame and a self-locking component. The fixed frame is installed on the ceiling, and a connecting piece is rotatably installed on it. The lower end of the connecting piece is provided with a hanging rod. On the set, there is a special-shaped groove with an open upper end inside. The lower end of the special-shaped groove is provided with a first limit groove and a second limit groove. There is a lock block in the special-shaped groove, and a guide is formed between the outer periphery of the lock block and the inner wall of the special-shaped groove. Channel, the lower end of the lock block is provided with a card slot that cooperates with the hanging rod. The side of the lock block near the first limit groove extends into the area above the first limit groove and is provided at the lower end of the side that can be moved downward by the self-locking member. When moving, guide the hanging rod into the guide surface of the first locking block of the locking groove, a protrusion is formed between the first limiting groove and the second limiting groove, and the locking groove is located between the protrusion and the second limiting groove. upper area. The present invention does not need to use tools, relies on the up and down movement of the self-locking member, and can move the hanging rod along the guide channel to complete disassembly and assembly, which is convenient and fast.
Description
technical field [0001] The invention relates to an LED display screen, in particular to a self-locking mechanism. Background technique [0002] At present, LED display screens are more and more widely used, and the display screens used in some special occasions, such as ceiling screens, are more and more popular among people. The sky screen is a screen installed at a high place. The maintenance and disassembly of the high place should be fast and stable, and the fewer tools used, the better. However, it is difficult to disassemble and assemble the existing sky screen, and the small-pitch screen cannot even be disassembled with tools. Therefore, it is urgent to design a tool-free installation mechanism to install the LED display. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a self-locking mechanism that can be disassembled and assembled without tools. [0004] The technical solution adopted by th...
