A limiting mechanism is arranged inside the connecting cylinder.

[0006] Preferably, the manual displacement mechanism includes a frame shaft fixedly penetrating through the inner side of the fixing frame. A swing arm is rotatably connected to the outer surface of the frame shaft. A grip is arranged at the top of the swing arm. Through the manual displacement mechanism, the sliding plate can be manually driven so that the plug rod is inserted into the connecting cylinder and is limited by the limiting mechanism.

[0007] Preferably, a first connecting shaft is fixedly penetrating through the inner side of the swing arm. A connecting rod is rotatably connected to the outer surface of the first connecting shaft. A second connecting shaft is fixedly connected to the outer surface of the sliding plate, and the outer surface of the second connecting shaft is rotatably connected to one end of the connecting rod away from the first connecting shaft.

[0008] Preferably, the limiting mechanism includes a fixed shaft fixedly connected to the inside of the connecting tube, and the outer surface of the fixed shaft is rotatably connected to a tow rod. The limiting mechanism can stably limit the special-shaped column, so that the connecting tube is relatively stably connected to the fixed frame, thereby indirectly completing the connection between the first box body and the second box body.

[0009] Preferably, an outer top spring is fixedly connected to the inner wall of the connecting tube, and one end of the outer top spring away from the connecting tube is fixedly connected to the outer surface of the towing rod.

[0010] Preferably, the connection tube is internally movably connected to a limit rod, one end of the limit rod close to the special-shaped column is provided with a hook claw, and the outer surface of the limit rod is movably sleeved with a limit spring.

[0020] Through the above technical solutions, during the use of the LED direct display screen box body, the connecting cylinder 15 and the fixing frame 2 can be relatively stably connected through the manual driving mechanism and the limiting mechanism, that is, the first box body 1 and the second box body 14 can be indirectly and quickly spliced and installed. During this process, it is not necessary to screw and install the screws one by one, which greatly improves the installation efficiency.

[0021] Specifically, the manual driving mechanism includes a frame shaft 8 fixedly penetrating through the inner side of the fixing frame 2, a swing arm 9 is rotatably connected to the outer surface of the frame shaft 8, and a grip 10 is arranged at the top of the swing arm 9.

[0022] Through the above technical solutions, during the process of the swing arm 9 rotating along the frame shaft 8, the first connecting shaft 11 can be driven to perform a partial circular motion, thereby driving the connecting bar 12.

[0023] Specifically, a first connecting shaft 11 is fixedly penetrating through the inner side of the swing arm 9, a connecting bar 12 is rotatably connected to the outer surface of the first connecting shaft 11, a second connecting shaft 13 is fixedly connected to the outer surface of the sliding plate 4, and the outer surface of the second connecting shaft 13 is rotatably connected to one end of the connecting bar 12 away from the first connecting shaft 11.

[0024] Through the above technical solutions, during the process of the connecting bar 12 being deflected and driven, the other end thereof will rotate along the second connecting shaft 13 and push and pull the sliding plate 4 through the second connecting shaft 13.

[0025] Specifically, the limiting mechanism includes a fixed shaft 16 fixedly connected to the inside of the connecting cylinder 15, and a drag bar 17 is rotatably connected to the outer surface of the fixed shaft 16.

[0026] Through the above technical solution, one end corresponding to the towing rod 17 is designed with a cut surface, and this design is for smoothly pushing out the inserting rod 5.

[0027] Specifically, an outer top spring 18 is fixedly connected to the inner wall of the connecting cylinder 15, and one end of the outer top spring 18 far from the connecting cylinder 15 is fixedly connected to the outer surface of the towing rod 17.

[0028] Through the above technical solution, when the outer top spring 18 pushes against the towing rod 17 to make it rotate along the fixed shaft 16, it can push against the inserting rod 5, so that the special-shaped column 6 is separated from the inside of the connecting cylinder 15.

[0029] Specifically, a limiting rod 19 is movably connected inside the connecting cylinder 15. A claw 20 is arranged at one end of the limiting rod 19 close to the special-shaped column 6, and a limiting spring 21 is movably sleeved on the outer surface of the limiting rod 19.

[0030] Through the above technical solution, the surface of the claw 20 is designed with a cut surface. When the limiting rod 19 is pulled, the claw 20 will slide along the inner wall of the connecting cylinder 15. Under normal conditions, the limiting spring 21 will push against the corresponding claw 20, so that the two claws 20 are in contact with each other.

[0031] Working principle: During the use of the LED direct display screen box, the manual driving mechanism and the limiting mechanism can be used to relatively stably connect the connecting tube 15 and the fixing frame 2, so that the first box body 1 and the second box body 14 can be indirectly connected and installed quickly. During this period, you only need to hold the handle 10 and move the swing arm 9 to make the swing arm 9 rotate clockwise along the frame axis 8. In this process, the connecting bar 12 can be driven to deflect through the first connecting shaft 11 and the second connecting shaft 13. The deflection of the connecting bar 12 makes the slide plate 4 slide along the strip hole 3, and finally drives the insertion rod 5 to be inserted into the connecting tube 15. During the insertion of the insertion rod 5, the insertion rod 5 will press against the tip section of the drag rod 17, and make the drag rod 17 rotate along the fixed axis 16, and at the same time squeeze the external push spring 18. Since the end of the special-shaped column 6 is designed with a section, it can push against the two sets of hooks 20 as the insertion rod 5 moves inward, so that they can be mutually The two sets of hooks 20 are respectively inserted into the corresponding limit grooves 7 on the surface of the special-shaped column 6 under the elastic return action of the limit spring 21. At this time, the hooks 20 can be stably stuck in the limit grooves 7 to complete the limit stability of the special-shaped column 6, so that the connecting tube 15 and the fixing frame 2 are stably connected, and finally the first box body 1 and the second box body 14 are quickly installed. When it is necessary to disassemble them, it is only necessary to pull the two sets of limit rods 19 outward to disengage the hooks 20 from the limit grooves 7. At this time, under the return action of the external push spring 18, it can push the drag rod 17 to rotate along the fixed axis 16 and push the insertion rod 5 outward, so as to easily pull out the special-shaped column 6, and the disassembly of the two sets of boxes can be completed. There is no need to screw the screws one by one during the entire disassembly and assembly process, which greatly improves the splicing efficiency.
