[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 to Figure 7As shown, this embodiment proposes an LED display screen hanging box and an LED display screen, including a box body 1, a display screen assembly 4 is arranged on the outer side of the box body 1, and connecting components 3 for installing the display screen assembly 4 are arranged at both ends of the box body 1. The connecting component 3 includes a connecting seat 31, and a card slot 32 is opened on the inner side of the connecting seat 31. The display screen assembly 4 and the card slot 32 are slidably matched. A positioning piece 33 is arranged at one end of the connecting seat 31 for limiting the separation of the display screen assembly 4 from the connecting seat 31 by manual operation, and a pushing component 2 is arranged on the inner side of the box body 1 for driving the connecting seat 31 to move longitudinally.

[0026] The pushing component 2 can drive the connecting seat 31 to move longitudinally so that the connecting seat 31 moves outward from the box body 1, which makes the connecting seat 31 extend to facilitate the installation of the display screen assembly 4, and then the display screen assembly 4 is slidably matched with the card slot 32, and the positioning member 33 is manually operated to limit the separation of the display screen assembly 4 and the connecting seat 31, which keeps the display screen assembly 4 and the connecting seat 31 fixed, thereby greatly improving the stability of the display screen assembly 4 after installation, and effectively avoiding the problem of the display screen assembly 4 and the connecting seat 31 being separated due to external force.

[0027] Furthermore, the display screen assembly 4 includes an LED display screen 41, and both ends of the outer wall of the LED display screen 41 are fixedly connected with a card block 42, and the two card blocks 42 are slidably matched with the corresponding card slots 32. One end of the top of the two card blocks 42 is provided with a positioning groove 43 corresponding to the positioning member 33, and the card block 42 is a T-shaped structure. The vertical section of the card block 42 is slidably connected to the inner wall of the card slot 32; the positioning member 33 includes a positioning rod 331 that passes through the top wall of the connecting seat 31, and the positioning rod 331 is connected to the The top wall of the connecting seat 31 is slidably connected, the bottom end of the positioning rod 331 is slidably matched with the corresponding positioning groove 43, the top of the positioning rod 331 is fixedly connected with a pull block 335, the middle part of the positioning rod 331 is fixedly connected with a stop block 332, the top wall of the slot 32 is provided with a receiving groove 333 that slidably matches with the stop block 332, and the positioning rod 331 is sleeved with a spring 334, the top end of the spring 334 is in contact with the top wall of the receiving groove 333, and the bottom end of the spring 334 is in contact with the stop block 332.

[0028] During installation, by pulling the pull block 335 upwards so that the stopper 332 cooperates with the receiving groove 333, the bottom end of the positioning rod 331 completely slides into the receiving groove 333. At this time, the spring 334 is compressed to accumulate potential energy, and then the card block 42 can be slidably matched with the card groove 32. When the positioning groove 43 on the card block 42 moves to the position of the positioning rod 331, the spring 334 releases the potential energy so that the positioning rod 331 and the positioning groove 43 are slidably matched. In this way, the card block 42 can be limited from being separated from the connecting seat 31, thereby ensuring the stable installation of the LED display screen 41.

[0029] During disassembly, the pull block 335 is pulled upwards to make the stop block 332 cooperate with the storage slot 333, so that the positioning rod 331 is disengaged from the positioning slot 43, so that the card block 42 can be directly slid out of the card slot 32, thereby realizing the disassembly of the LED display screen 41. The entire disassembly and assembly process is simple to operate, and the LED display screen 41 can be quickly disassembled and assembled.

[0030] Further, the pushing assembly 2 includes a bidirectional screw rod 21, which is rotatably connected to the inner side of the box body 1, and both ends of the bidirectional screw rod 21 are threadedly connected to the movable blocks 22, one end of the two movable blocks 22 is hinged with a connecting rod 1 23, the end of the connecting rod 1 23 away from the movable block 22 is hinged to one end of the connecting seat 31, and the other end of the connecting seat 31 is hinged with a connecting rod 24, and the end of the connecting rod 24 away from the connecting seat 31 is hinged to the inner wall of the box body 1, and the outer wall of the box body 1 is provided with a through groove 5, and the connecting rod 24 and the connecting rod 1 23 are both located in the through groove 5. On the inner side, a manual part 25 for driving the bidirectional screw rod 21 to rotate is provided in the middle part of the bidirectional screw rod 21, and the manual part 25 includes a bevel gear 1 251, and the bevel gear 1 251 is fixedly connected to the middle part of the bidirectional screw rod 21. The bottom end of the inner side of the box body 1 is fixedly connected to a mounting frame 252, and the middle part of the mounting frame 252 is rotatably connected to a rotating shaft 253 that passes through the mounting frame 252, and the top end of the rotating shaft 253 is fixedly connected to a bevel gear 254, which is meshed with the bevel gear 1 251, and the bottom end of the rotating shaft 253 is fixedly connected to a handwheel 255.

[0031] By turning the hand wheel 255, the rotating shaft 253 drives the bevel gear 2 254 to rotate, which makes the bevel gear 1 251 drive the bidirectional screw 21 to rotate synchronously, and the two movable blocks 22 translate toward or away from each other, which changes the angle between the two connecting rods 1 23 and the movable blocks 22, so that the corresponding connecting seat 31 moves away from or close to the box body 1, thereby facilitating the installation or removal of the LED display screen 41.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
