[0020] S4: Then, use a magnet to slide the No. 1 connecting block out of the lower mounting block and back into the upper mounting block of the LED display screen that needs to be disassembled, thereby canceling the connection between the upper and lower LED displays. Then push it out to disassemble it.

[0021] The beneficial effects of this invention are:

[0022] 1. This invention enables rapid installation of LED displays through a locking mechanism. Locking holes are provided on the mounting rod, which cooperate with the locking mechanism on the LED display to complete the rapid installation. The locking mechanism uses a fixing block and a telescopic spring to secure the LED display in the locking hole on the mounting rod, making it convenient and quick to install. Simultaneously, the upper and lower mounting blocks allow the LED displays to cooperate, connect, and interact with each other, resulting in a more stable installation. Furthermore, the upper and lower mounting blocks ensure that the LED displays remain aligned, preventing large height differences that could affect the display effect.

[0023] 2. This invention, through the arrangement of a second gear, a rotating rod, and a moving rod on the reinstallation rod, and a first gear, a second rack, and a third rack in the locking mechanism, can unlock the locking mechanism, facilitating its quick disassembly. The rotating rod and the moving rod can drive the first gear to rotate via the second gear, which in turn drives the second gear to rotate in conjunction with the unlocking mechanism, thus unlocking the locking mechanism. At the same time, the moving rod does not affect the removal of the locking mechanism.

[0024] 3. This invention enables the simultaneous unlocking of multiple locking mechanisms by using a connecting rod between the first racks, resulting in high disassembly efficiency and ease of use. When disassembling a single LED display, it is possible to choose not to install the connecting rod and disassemble a single LED display. When disassembling multiple LED displays or disassembling them completely, the installed connecting plate can improve disassembly efficiency, reduce the time required, and reduce time costs.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0037] like Figures 1 to 8 As shown, a specific embodiment of the present invention provides an LED display screen, an LED module assembly, and a method for assembling and disassembling the same. The assembly includes an LED display screen 1 and a bracket 2 disposed around the periphery of the LED display screen 1. Multiple mounting rods 4 are evenly arranged in the middle of the bracket 2. Crossbars 3 are fixedly installed at both ends of the bracket 2. The LED display screen 1 is fixedly installed on the mounting rods 4. A locking mechanism is provided on the back of the LED display screen 1. Locking holes are provided on the mounting rods 4, and the locking mechanism cooperates with the locking holes. An upper mounting block 5 is fixedly installed on the upper part of the back of the LED display screen 1, and a lower mounting block 8 is fixedly installed on the lower part of the back of the LED display screen 1. A first hole is opened in the middle of the upper mounting block 5. A weak magnet 13 is fixedly installed at the bottom of the first hole. A first connecting block 12 is provided above the weak magnet 13 and is slidable. A second hole is opened in the lower mounting block 8. A strong magnet 11 is fixedly installed at the top of the second hole. The first and second holes are aligned. The first connecting block 12 can be attracted and fixed by the strong magnet 11. A back plate 6 is fixedly installed on the back of the bracket 2 and the crossbars 3.

[0038] By adopting the above technical solution, the present invention enables quick installation of the LED display screen 1 through the cooperation of the mounting rods 4 and the locking mechanism on the back of the LED display screen 1. It is simple to use. The brackets 2 and crossbars 3 are cut to the appropriate size according to the user's actual needs. After cutting to the appropriate size, the brackets 2 and crossbars 3 confirm the size frame of the display screen. Then, multiple mounting rods 4 are installed in the middle of the brackets 2 according to the size of the LED display screen 1. The distance between the mounting rods 4 is the width of the LED display screen 1. After all the mounting rods 4 are installed, the worker installs the LED display screen 1 onto the mounting rods 4. Multiple locking holes are provided on the mounting rods 4, and the distance between the locking holes is consistent with the length of the LED display screen 1, ensuring a perfect fit between the LED display screens 1. After the LED display screen 1 is installed, the worker uses a magnet to attract the first connecting block 12. The first connecting block 12 is attracted by the magnet, and then the worker moves the magnet to move the first connecting block. 12 is moved, and the first connecting block 12 is disengaged from the weak magnet 13. The first connecting block 12 moves from the upper mounting block 5 to the lower mounting block 8 and is attached to the strong magnet 11 in the lower mounting block 8. After the first connecting block 12 is attached to the strong magnet 11, the first connecting block 12 is located between the upper mounting block 5 and the lower mounting block 8, so that the two LED displays 1 interact with each other, which can be more aligned, flatter, and have a better display effect. At the same time, due to the action of the first connecting block 12, the connection of the LED displays 1 is tighter and less likely to fall off. The attraction of the magnet to the first connecting block 12 is greater than that of the weak magnet 13 and the strong magnet 11. Then, the staff moves the first connecting blocks 12 one by one to the lower mounting block 8 with the magnet to engage with the strong magnet 11. At the same time, because the attraction of the magnet to the first connecting block 12 is greater than that of the weak magnet 13 and the strong magnet 11, when it is necessary to remove the first connecting block 12, it can be disengaged from the strong magnet 11 for removal.

[0039] Specifically, such as Figures 3 to 8 As shown, the locking mechanism includes a mounting block 30, which is fixedly installed in the middle of the back of the LED display screen 1. A second mounting groove 34 is provided at the upper end of the mounting block 30, a first mounting groove 33 is provided in the middle of the mounting block 30, and a third mounting groove 35 is provided at the lower end of the mounting block 30. A fixing block 21 is slidably installed in the first mounting groove 33. A sliding groove 25 is provided on the partition between the first mounting groove 33 and the second mounting groove 34. A second moving plate 23 is slidably installed in the second mounting groove 34. The second moving plate 23 is fixedly connected to the tail end of the fixing block 21 and can slide on the sliding groove 25. A telescopic spring 24 is fixedly provided on the side wall of the second moving plate 23. A mounting cover 31 is fixedly installed at the rear end of the mounting block 30, and the other end of the telescopic spring 24 is fixedly installed on the mounting cover 31.

[0040] By adopting the above technical solution, during installation, the locking mechanism is installed by first having the worker pinch the two fixing blocks 21 and move them into the mounting block 30, then aligning them with the locking holes on the mounting rod 4 and inserting them, and then pushing the mounting block 30 to move. After the mounting block 30 moves into the locking hole, the fixing block 21 extends into the fixing groove under the action of the telescopic spring 24, and then the installation of the LED display screen 1 is completed. At the same time, the movement of the fixing block 21 causes the first moving plate 22 and the second moving plate 23 to slide in the sliding groove 25. The mounting cover 31 is fixedly installed on the mounting block 30 by the set buckle 36. The side wall of the mounting cover 31 is provided with a protruding plate, which blocks the openings of the second mounting groove 34 and the third mounting groove 35.

[0041] Specifically, such as Figures 3 to 8 As shown, a first gear 29 is provided in the middle of the third mounting slot 35. A second rack 26 and a third rack 28 are respectively installed on both sides of the first gear 29. The second rack 26 and the third rack 28 mesh with the first gear 29. A sliding groove 25 is provided on the partition between the first mounting slot 33 and the third mounting slot 35. A first movable plate 22 is fixedly installed on the top of the second rack 26 and the third rack 28. The first movable plate 22 is fixedly connected to the fixed block 21 and can slide on the sliding groove 25. A rotating shaft 44 is provided in the middle of the first gear 29. The upper end of the rotating shaft 44 is fixedly installed on the upper wall of the third mounting slot 35. A first bearing 27 is provided below the first gear 29. The first bearing 27 is fixedly installed on the bottom of the mounting block 30. The lower end of the rotating shaft 44 is fixedly installed on the first bearing 27.

[0042] By adopting the above technical solution, the first gear 29, the second rack 26, and the third rack 28 installed in the third mounting slot 35, the rotation of the first gear 29 can control the movement of the second rack 26 and the third rack 28. The top ends of the second rack 26 and the third rack 28 are fixedly connected to the first moving plate 22. The movement of the second rack 26 and the third rack 28 drives the first moving plate 22 to move. The second rack 26 and the third rack 28 are arranged facing each other, so that they move towards each other when moving. The opposite movement of the second rack 26 and the third rack 28 drives the two first moving plates 22 to slide in the groove. Within 25, the moving plate 22 moves towards each other, causing the fixed block 21 to move into the mounting block 30, thus eliminating the engagement with the locking hole and facilitating quick disassembly for maintenance or replacement. The gear 29 is rotatably mounted on the bottom of the mounting block 30 via the bearing 27 and the rotating shaft 44. The bottom of the rotating shaft 44 is flush with the bottom of the mounting block 30. The bottom of the rotating shaft 44 has a second connecting groove, which can be engaged with external tools to allow the gear 29 to rotate and unlock the locking mechanism, making disassembly easier.

[0043] Specifically, such as Figures 3 to 8 As shown, the bottom of the mounting rod 4 has an installation opening, and a sleeve 37 is fixedly installed inside the installation opening. A rotating rod 41 is rotatably installed inside the sleeve 37. The inner wall of the rotating rod 41 is set with a movable rod 42, which can slide inside the rotating rod 41. A first limiting rod is set on the side wall of the movable rod 42, and a first limiting groove is opened on the inner wall of the rotating rod 41. The first limiting rod and the first limiting groove cooperate, and the movable rod 42 can rotate together with the rotating rod 41. A second connecting block 45 is set at the top of the movable rod 42. A second connecting groove is opened on the bottom wall of the rotating shaft 44, and the second connecting block 45 cooperates with the second connecting groove. A first magnet 39 is fixedly installed at the bottom of the movable rod 42, and a second gear 38 is fixedly installed at the bottom of the rotating rod 41. An installation hole is opened in the middle of the second gear 38, and the rotating rod 41 is installed in the installation hole. A second magnet 40 is fixedly installed at the bottom of the installation hole. The first magnet 39 and the second magnet 40 repel each other. A hexagonal connecting groove is opened at the bottom of the second gear 38.

[0044] By adopting the above technical solution, the sleeve 37 is set on the mounting rod 4, making it easier to install. Then, a rotating rod 41 is installed inside the sleeve 37. A limit ring 43 is set on the rotating rod 41 to prevent it from moving after it is installed in place. At the same time, the rotating rod 41 can rotate freely inside the sleeve 37. A moving rod 42 is set inside the rotating rod 41, and a first limit rod is set on the outer wall of the moving rod 42, so that the moving rod 42 can only slide up and down inside the rotating rod 41 and cannot rotate. At the same time, a second connecting block 45 is set at the top of the moving rod 42. The second connecting block 45 engages with the rotating shaft 44, so that the operator can rotate the rotating rod 41 to drive the first gear 29 to rotate and unlock the locking mechanism. At the same time, a first magnet 39 is set at the bottom of the moving rod 42, and a second magnet 40 is set inside the second gear 38. The second gear 38 is fixedly set at the bottom of the rotating rod 41. The rotation of gear 38 drives the rotating rod 41 to rotate. The magnets 39 and 40 generate a repulsive force, which pushes the moving rod 42 upward into the rotating rod 41. The moving rod 42 moves upward and engages with the rotating shaft 44, completing the connection. At the same time, the moving rod 42 will move downward under the action of external force, ensuring that the moving rod 42 will not obstruct the locking mechanism when it is removed. In addition, a hexagonal connecting groove is provided on the lower wall of gear 38, which can be rotated by external force to unlock the locking mechanism.

[0045] Specifically, such as Figures 2 to 8As shown, an unlocking mechanism is provided below the mounting rod 4. The unlocking mechanism includes a housing 19. A first bevel gear 18 is provided on the upper end of the inner wall of the housing 19. A second bevel gear 20 is provided on the side of the first bevel gear 18. The second bevel gear 20 is located on the side wall of the housing 19. The first bevel gear 18 and the second bevel gear 20 are meshed. A connecting shaft 17 is installed on the side wall of the first bevel gear 18. The connecting shaft 17 passes through the housing 19. A hexagonal connecting block 16 is fixedly installed at the top of the connecting shaft 17. The hexagonal connecting block 16 can cooperate with the hexagonal connecting groove. A knob 10 is fixedly installed on the side wall of the second bevel gear 20.

[0046] By adopting the above technical solution, the locking mechanism can be unlocked through the set unlocking mechanism. The operation is simple and quick. When unlocking the locking mechanism is required, the operator holds the unlocking mechanism and aligns the hexagonal connecting block 16 on the upper wall of the unlocking mechanism with the hexagonal connecting groove on the lower wall of the second gear 38, ensuring that the hexagonal connecting block 16 and the hexagonal connecting groove are properly engaged. Then, the operator turns the knob 10. The rotation of the knob 10 drives the second bevel gear 20 to rotate, which in turn drives the first bevel gear 18 to rotate. The rotation of the first bevel gear 18 drives the connecting shaft 17 and the hexagonal connecting block 16 to rotate, which in turn drives the second gear 38 to rotate, which in turn drives the rotating rod 41 and the moving rod 42 to rotate. The rotating shaft 44 and gear 29 rotate, which in turn moves racks 26 and 28. The movement of racks 26 and 28 moves moving plate 22, which in turn moves fixing block 21 into mounting block 30. After fixing block 21 is inside mounting block 30, the operator uses a magnet to move connecting block 12 into upper mounting block 5, so that the LED display 1 to be disassembled is no longer connected to the surrounding LED display 1. Then the LED display 1 is taken out. When taking it out, the rotating shaft 44 moves outward, which pushes connecting block 45 and moving rod 42 downward, so that they are no longer connected. The LED display 1 can then be taken out for easy repair or replacement.

[0047] Specifically, such as Figures 3 to 8 As shown, the bottom of the mounting rod 4 has a No. 4 mounting groove, in which a sliding strip 14 is fixedly installed. A No. 1 rack 9 is slidably installed in the sliding strip 14. The No. 1 rack 9 meshes with the No. 2 gear 38. There are two No. 1 mounting grooves 33 and No. 2 mounting grooves 34 symmetrically arranged. The length of the No. 3 mounting groove 35 is equal to the length of the two No. 1 mounting grooves 33. The inner wall of the locking hole has symmetrically arranged fixing grooves, which cooperate with the fixing block 21. The side wall of the mounting cover 31 is provided with a buckle 36, and the side wall of the mounting block 30 is provided with a slot. The buckle 36 engages with the slot. Multiple buckles 36 and slots are evenly arranged.

[0048] By adopting the above technical solution, the connecting rod 7 connecting rack 9 to rack 9 can drive rack 9 to move while rotating gear 38. The movement of rack 9 drives the other racks 9 in the same row to move through the connecting rod 7. The movement of rack 9 drives the other gears 38 in the same row to rotate, so that all gears 38 in the same row rotate. This allows for the disassembly of a row of LED displays 1 at once. This method is more efficient when dealing with large-scale damage or dismantling and relocation, as it eliminates the need to disassemble them one by one, saving time. At the same time, the staff can install the connecting rod 7 according to the actual situation, making it more flexible and efficient.

[0049] Specifically, such as Figures 3 to 8 As shown, a concave ring is provided on the inner wall of the sleeve 37, and a limit ring 43 is provided on the outer wall of the rotating rod 41. The limit ring 43 cooperates with the concave ring. The second connecting block 45 is cross-shaped, and a chamfer is provided on the outer wall of the second connecting block 45. An angle is provided in the second connecting groove. Multiple LED displays 1 are provided. Each LED display 1 is provided with a second gear 38 and a first rack 9. Multiple locking holes are provided on the mounting rod 4. A connecting rod 7 is provided between the multiple first racks 9. The connecting rod 7 is fixedly installed on the first rack 9 by fixing screws 32.

[0050] By adopting the above technical solution, the concave ring inside the sleeve 37 and the limiting ring 43 on the outer wall of the rotating rod 41 can better fix the rotating rod 41, making it difficult to move up and down and only able to rotate, thus playing a limiting role. At the same time, the chamfer on the outer wall of the second connecting block 45 and the bevel in the second connecting groove can reduce the obstruction when the rotating shaft 44 moves, and can more smoothly push the moving rod 42 downward, making it easier to remove the locking mechanism.

[0051] An assembly and disassembly method for an LED display screen and an LED module assembly, wherein the assembly and disassembly method employs an LED display screen and an LED module assembly as described in any one of claims 1-9, and the method includes the following steps;

The length of the mounting rod is cut according to the assembly size. Then install the LED display on the mounting rod, align the locking mechanism on the back of the LED display with the locking hole on the mounting rod, and then push it in to complete the installation of the LED display. Then move the No. 1 connecting block to the lower mounting block and stick it to the strong magnet by attracting the magnet.

[0053] S2: After completing the installation of the LED display screen, go to the back of the mounting rod and install the sleeve into the mounting opening at the bottom of the mounting rod. Then install the rotating rod into the sleeve, so that the limiting ring on the rotating rod engages with the concave ring inside the sleeve. Then rotate the rotating rod to drive the second connecting block on the moving rod to engage with the second connecting groove on the rotating shaft. Then install the sliding strip into the fourth mounting groove at the bottom of the mounting rod and mesh the first rack on the sliding strip with the second gear at the bottom of the rotating rod. After repeating the installation multiple times, connect the horizontal first racks together through the connecting rod.

[0054] S3: When it is necessary to disassemble it, place the unlocking mechanism in the row that needs to be disassembled, engage the hexagonal connecting block on the upper wall of the unlocking mechanism with the hexagonal connecting slot on the second gear, then rotate the knob to drive the second gear to rotate and move its fixing block into the mounting block to unlock it. At the same time, the connecting rod 7 drives all the second gears in the horizontal direction to rotate and unlock it.

[0055] S4: Then, use a magnet to slide the No. 1 connecting block out of the lower mounting block and back into the upper mounting block of the LED display screen that needs to be disassembled, thereby canceling the connection between the upper and lower LED displays. Then push it out to disassemble it.
