[0022] like Figures 1 to 4 As shown, this utility model provides an easy-to-assemble LED display screen, including a housing 10. The housing 10 has at least one set of mounting positions 11, and display modules 20 are detachably mounted on all mounting positions 11. Each display module 20 has a positioning plate 21 on its back side that mates with the corresponding mounting position 11. The positioning plate 21 is deformable and bendable, and is hinged to the lower end of the back side of the display module 20. Each mounting position 11 has a corresponding slot 14 that mates with the corresponding positioning plate 21. The display module 20 is a conventional LED display module; specific details can be found in existing technology and will not be described in detail here. The display modules 20 can have a rectangular structure, and can be assembled by splicing them together to form a large display screen. The enclosure 10 can be made of aluminum alloy, which has good strength and lightness. The enclosure 10 can be designed with a detachable back panel to facilitate maintenance of the interior of the enclosure 10 from the rear. In addition, the enclosure 10 is equipped with power supply components and control components that are electrically connected to each other (not shown in the figure). All the display modules 20 are electrically connected to the power supply components and control components to provide power and control for all display modules 20. The specific structure and connection method are existing technologies. You can refer to the prior art disclosed in the prior art of display cabinet and display screen with patent number CN202122020966.X. It will not be described in detail in this application.

[0023] When installing the display module 20, for ease of insertion, the lower-level display module 20 is generally installed first. First, the positioning plate 21 is aligned with the slot 14, and then inserted from top to bottom. The positioning plate 21 can deform and bend to ensure smooth insertion into the slot 14, achieving the purpose of positioning and aligning the display module 20 with the mounting position 11. The display module 20 is then fixed with screws or magnets. Furthermore, the slot 14 has a gradually decreasing diameter from the outside in. This tapered structure of the slot 14 helps guide the accurate insertion of the positioning plate 21 and improves the tightness of the connection.

[0024] See Figure 2 In one specific embodiment of this application, the housing 10 is provided with a plurality of horizontal bars 12 and vertical bars 13 arranged in a grid pattern. Adjacent horizontal bars 12 and vertical bars 13 enclose each other to form mounting positions 11, and slots 14 are provided on the horizontal bars 12. The horizontal bars 12 and vertical bars 13 are arranged in an alternating pattern to form rectangular mounting positions 11. The size of the mounting positions 11 is designed according to the actual size of the display module 20 to ensure that the display module 20 can be tightly assembled and installed. The interior of the mounting positions 11 has space to accommodate the positioning limiting member 30. In this application, the display module 20 is detachably fixed to the housing 10 by magnetic attraction. A plurality of first magnetic blocks 15 are provided on the edge of all mounting positions 11, and a second magnetic block 27 that can cooperate with the corresponding first magnetic block 15 is provided on the back of all display modules 20. To facilitate disassembly, all display modules 20 are provided with pry slots 28 on their tops. These pry slots 28 can be positioned corresponding to the first magnetic block 15, allowing a prying tool to be inserted into the back of the display module 20 to push it outwards and release the magnetic attraction. Alternatively, screws and nuts can be used instead of magnetic attraction for enhanced stability.

[0025] Specifically, to facilitate the assembly and disassembly of the display module 20, the positioning plate 21 adopts a rotatable hinge structure. Two sets of mounting blocks 22 are provided on the lower end of the back of the display module 20. The upper end of the positioning plate 21 is rotatably mounted between the two sets of mounting blocks 22 via a rotating shaft 23. When maintenance or disassembly is required, first release the screws or magnets securing the display module 20, then pull the display module 20 outwards in parallel. At this time, the positioning plate 21 rotates, but its lower end remains inserted in the slot 14 (see the attached instruction manual). Figure 4 After being moved out in parallel, there is space to continue lifting the display module 20 upwards, completing the disassembly operation. Furthermore, the flared opening of the slot 14 provides sufficient rotation space for the positioning plate 21.

[0026] Furthermore, a limiting block 24 is provided on the back of the display module 20, located on both sides of the positioning block 21. The limiting block 24 has a locking groove 25, and both sides of the positioning block 21 are provided with spherical locking heads 26 that can cooperate with the locking groove 25. When the positioning block 21 is in a vertical position, the spherical locking heads 26 will lock into the locking groove 25, forming a locked state to prevent the positioning block 21 from accidentally flipping over; during disassembly, under the action of external force, the spherical locking heads 26 can be dislodged from the locking groove 25, and the positioning block 21 can rotate.

[0027] This utility model provides an easy-to-assemble LED display screen. During installation, the positioning limiter 30 can be used to align the display module with its mounting position 11, preventing the display module 20 from being tilted or misaligned during installation, achieving quick correction and positioning. Magnetic blocks are used for fixation, ensuring the stability of the display module 20 installation and facilitating disassembly and maintenance. In addition, the design of the pry slot 28 makes the replacement of a single display module 20 more convenient, and the tapered design of the slot 14 and the cooperation between the spherical clip 26 and the slot 25 prevent the positioning limiter 30 from affecting disassembly.

[0028] During installation, first align the display module 20 with the mounting position 11, align the positioning plate 21 with the slot 14 on the crossbar 12, gently press down on the display module 20, the positioning plate 21 enters the slot 14, at the same time the ball head 26 engages with the slot 25, the second magnetic block 27 on the back of the display module 20 attracts the first magnetic block 15 on the edge of the mounting position 11, fixing the display module 20 and ensuring its stable installation, thus completing the initial installation.

[0029] When disassembly is required, use a pry tool to insert into the pry slot 28 on the top of the display module 20, gently pry the display module 20 to release the second magnetic block 27 from the first magnetic block 15, then pull the display module 20 outward, the ball-shaped clip 26 disengages from the slot 25, and then lift the display module 20 upward, the positioning plate 21 exits from the slot 14, and the disassembly is completed.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of the technical solution of this utility model.
