[0027] The adjusting mechanism 2 includes an installation sheet 201 arranged in an “L” shape, a first mounting head 202 and a second mounting head 204 are arranged on the inner wall and the bottom of the installation sheet 201 respectively, a first screw groove 203 and a second screw groove 205 are formed in the first mounting head 202 and the second mounting head 204 respectively, and a lock catch mechanism 3 is arranged in each of the first screw groove 203 and the second screw groove 205, the plurality of transverse frames on the mounting frame are provided with adjusting grooves extending along the length direction, and the damping rotating rod penetrating the transverse frame enables the adjusting mechanism to be flexibly adjusted at different positions. During installation, the position of the display unit can be finely adjusted according to actual needs, ensuring the accuracy of splicing and the overall flatness, effectively solving the problem that the installation position is difficult to accurately adjust due to the single fixed mode of the traditional structure, and the damping rotating rod and the adjusting groove cooperate to provide moderate damping force, which ensures the flexibility of adjustment while keeping the adjusted position stable and not prone to loosening or displacement. This helps to improve the stability of the large-screen spliced LED display unit during long-term use, reduces the change of the splicing gap or the misalignment of the display unit caused by factors such as vibration and external force, and in addition, the arrangement of the plurality of transverse frames and the adjusting grooves enables the adjusting structure to adapt to the installation needs of LED display units of different sizes and specifications. Whether it is a small indoor splicing screen or a large outdoor splicing screen, appropriate installation can be achieved by adjusting the position of the adjusting mechanism on the transverse frame, enhancing the versatility and applicability of the lock catch connection structure.

[0028] Referring to Figure 1 , Figure 3 , Figure 4 , the lock catch mechanism 3 includes a first magnetic catch 301 and a second magnetic catch 304, a first magnetic attraction groove 303 is formed at the front end of the first magnetic catch 301, and a second magnetic attraction groove 305 is formed at the front end of the second magnetic catch 304, the selection of the first magnetic attraction groove and the internal magnet material such as ferrite can ensure that the magnetic attraction performance remains stable in harsh outdoor environments, ensuring that the display unit and the mounting frame are firmly connected, effectively resisting the influence of external environmental factors on the connection stability, and enabling the large-screen spliced LED display unit to operate reliably outdoors for a long time.

[0029] Referring to Figure 1 , Figure 3 , Figure 4, the first magnetic suction groove 303 has a larger aperture than the second magnetic suction groove 305, and the magnet material in the first magnetic suction groove 303 is ferrite, and the magnet material in the second magnetic suction groove 305 is neodymium iron boron. The first magnetic suction groove has a larger aperture and is made of ferrite magnet material.

The first screw block 302 is screwed with the first screw groove 203, and the second screw block 306 is screwed with the second screw groove 205. The first and second magnetic buckles are respectively provided with first and second screw blocks, which are screwed with the first and second screw grooves on the adjusting mechanism to realize the detachable connection between the magnetic buckle and the adjusting mechanism. This screwing method not only ensures firm installation, but also allows for easy and quick disassembly when maintenance or replacement of the display unit is required, reducing maintenance costs and difficulty. The screw connection provides reliable mechanical connection, ensuring that the magnetic buckle and the adjusting mechanism are tightly connected and not easily loosened. This helps to ensure the structural stability of the entire large-screen tiled LED display unit, improving display effect and service life.

[0031] Referring to Figure 1 , the first magnetic suction groove 303 is used in cooperation with the outdoor model magnetic block LED display screen, and the second magnetic suction groove 305 is used in cooperation with the indoor model LED display screen. The first magnetic suction groove cooperates with the outdoor model magnetic block LED display screen, and the second magnetic suction groove cooperates with the indoor model LED display screen. This precise cooperation design ensures that the display unit and the mounting rack are tightly and stably connected in different environments.

[0035] The second magnetic attraction slot has a smaller aperture and is made of neodymium iron boron magnet material, which can provide sufficient suction in the relatively mild indoor environment to ensure firm fixation of the display unit. The first screw block and the second screw block arranged on the back of the first magnetic buckle and the second magnetic buckle are respectively screwed with the first screw groove and the second screw groove, realizing detachable connection of the magnetic buckle and the adjustment mechanism, facilitating installation and disassembly;

[0036] Through the cooperation of the adjustment mechanism and the lock buckle mechanism, the technical problem of traditional lock buckle connection structure that needs to replace different magnetic buckles due to the difference between indoor and outdoor environments, resulting in workers needing to remove and replace magnetic buckles one by one during installation, complicated operation and low efficiency is solved, improving the installation efficiency, stability and universality of the large-screen spliced LED display unit.
