LED display can realize the conversion between different forms of multiple information presentation modes, and can be used indoors and outdoors, which has advantages that other display screens cannot match.

[0003] The LED display screen in the prior art is usually installed by magnetically fixing it to the box through magnets. Although it can be quickly disassembled and installed when the LED display screen fails, the use of only magnetic fixation will cause the LED display screen to have poor stability during use and easily fall off. For example, when the LED display screen and the box are installed, bolts and other fixing parts are used or glue is injected at the connection parts for connection. Although it can improve the stability of the LED display screen, it is very time-consuming when the LED display screen needs to be disassembled and repaired, which seriously affects the maintenance efficiency. Summary of the invention

[0014] Optionally, the blocking mechanism includes an airbag installed on the back of the display screen, air pipes are installed inside the two connecting ends, the ends of the two air pipes away from the connecting ends are connected to the airbag, and multiple connecting ropes are installed on the outer wall of the airbag away from the display screen body.

[0015] Optionally, two electric telescopic rods are installed inside the two sliding blocks, the telescopic ends of the two electric telescopic rods are commonly connected to a piston plate, and the upper and lower ends of the two sliding blocks are rotatably installed with limit plates for limiting themselves.

[0016] The beneficial effects of the present invention are:

[0017] 1.

[0038] As a technical optimization solution of the present invention, a cavity is provided inside the two movable blocks 10, and connecting ends 24 are installed at the upper and lower ends of the two movable blocks 10. The two movable blocks 10 are rotatably connected to the back of the display screen through the connecting ends 24 provided at the upper and lower ends, and a circular hole 23 connected to the cavity is provided inside the two connecting ends 24.

[0039] As a technical optimization solution of the present invention, a rectangular groove 29 is provided at one end of the two movable blocks 10 away from the rotating part, and sliding blocks 26 extending into the cavity are slidably installed inside the two rectangular grooves 29. The ends of the two sliding blocks 26 away from the movable block 10 are connected to the connecting blocks 22 close to them, and limiting grooves 25 are provided inside the two connecting blocks 22.

[0040] As a technical optimization solution of the present invention, the inside of the two fixing blocks 5 is provided with a slide groove 15 connected to the connection groove 14, and the inside of the two slide grooves 15 is slidably installed with a limit block 16, and the two limit blocks 16 are inserted and adapted to the corresponding limit grooves 25. The two limit blocks 16 are located at one end of the connection groove 14 and are both set as an arc surface. When the display screen body 1 is installed on the front of the box body 2, the arc surface of the limit block 16 can be automatically squeezed after the two connection blocks 22 are inserted into the corresponding connection grooves 14, and after the connection block 22 completely enters the connection groove 14, the limit block 16 can also enter the limit groove 25 to limit and fix the connection block 22, so as to assist in limiting and fixing the display screen body 1.

[0041] As a technical optimization solution of the present invention, the ends of the two limit blocks 16 close to each other are connected to the inner wall of one side of the slide slot 15 through the spring 17, and the ends of the two limit blocks 16 close to each other are installed with mounting blocks extending to the outside of the slide slot 15, and the outer walls of the two mounting blocks located outside the slide slot 15 are rotatably installed with connecting rods 11. With the help of the provided spring 17, the limit blocks 16 can be driven to automatically elastically reset inside the slide slot 15.

[0042] As a technical optimization solution of the present invention, a connecting seat 18 is installed inside the box body 2, and the ends of the two connecting rods 11 away from the mounting block are both rotatably mounted on the bottom end of the connecting seat 18, and a pull rod 6 is installed on the top of the connecting seat 18, and a ring 19 is installed on the top of the pull rod 6. By pulling up the pull rod 6, the connecting seat 18 is driven to move upward together, and the two connecting rods 11 are driven to rotate in a direction close to each other, and the two mounting blocks and the limit blocks 16 are pulled to move in a direction close to each other, so that the two limit blocks 16 are respectively stored in the corresponding slide grooves 15; and with the help of the ring 19 set on the top of the pull rod 6, it is convenient for the staff to use tools to lift the pull rod 6 upward, and drive and pull rod 6 to move upward.

[0043] As a technical optimization solution of the present invention, the blocking mechanism includes an airbag 9 installed on the back of the display screen, and air pipes 20 are installed inside the two connecting ends 24. The ends of the two air pipes 20 away from the connecting ends 24 are connected to the airbag 9, and a plurality of connecting ropes 21 are installed on the outer wall of the airbag 9 away from the display screen body 1. Through the air pipe 20, the air in the internal cavity of the movable block 10 can be transported to the inside of the airbag 9, so as to inflate the airbag 9; and the connecting rope 21 is provided to facilitate connecting it with the airbag 9 on the back of the other display screen body 1.

[0044] As a technical optimization solution of the present invention, two electric telescopic rods 27 are installed inside the two sliding blocks 26, and the telescopic ends of the two electric telescopic rods 27 are connected to the piston plate 28. The upper and lower ends of the two sliding blocks 26 are rotatably installed with limit plates 30 for limiting themselves. The bottom ends of the two movable blocks 10 are pre-opened with air inlets, and the insides of the two air inlets are preset with one-way valves, so that the outside air can enter the cavity through the air inlet; the sliding block 26 moves inside the cavity, driving the piston plate 28 to squeeze the air inside the cavity and transport it to the inside of the airbag 9; and the piston plate 28 can also be driven to move inside the cavity by the extension and contraction of the telescopic ends of the two electric telescopic rods 27; two driving devices are preset inside the two sliding blocks 26, and the output ends of the two driving devices are respectively connected to the rotating parts of the two limit plates 30, so that the two limit plates 30 can be driven to rotate and adjust.

[0045] In the present invention, when the user uses the device, the box body 2 is first installed on a designated bracket or wall, and then the two movable blocks 10 are rotated to be perpendicular to the display screen body 1, and then the guide rods 8 at the four corners of the display screen body 1 are aligned with the positions of the guide grooves 4 set on the front of the box body 2, and the display screen body 1 is manually pushed toward the box body 2, so that multiple guide rods 8 are inserted into the corresponding guide grooves 4, and multiple first magnets 3 are magnetically fixed to multiple second magnets 7, so as to achieve the effect of preliminary installation of the display screen body 1.

[0046] As the display screen body 1 is pushed manually, the connection block 22 of the two movable blocks 10 away from one end of the display screen body 1 enters the connection groove 14 opened in the fixed block 5, and squeezes the arc surface of the two limit blocks 16, so that the two limit blocks 16 shrink in the corresponding slide groove 15 with the help of the elasticity of the spring 17, until the two connection blocks 22 completely enter the connection groove 14, the two limit blocks 16 are not squeezed and are reset with the help of the elasticity of the spring 17 and enter the corresponding limit groove 25, and the positions of the two connection blocks 22 are limited and fixed, so that the display screen body 1 and the box body 2 can be connected and installed for a second time, further improving the stability of the display screen body 1 installed on the front side of the box body 2, and facilitating the subsequent use of the display screen body 1.

[0047] In order to improve the dustproof and waterproof performance of the display screen body 1 during subsequent use, and reduce the adverse effects of dust and rainwater entering the interior of the box 2 through the connection gap between the display screen body 1 and the box 2 on the use of the display screen body 1, before the display screen body 1 is installed on the front of the box 2, such as Figure 6 and Fig. 9As shown, at this time, the two movable blocks 10 are in a vertical state with the display screen body 1, and the two ends of the external round rod are respectively inserted into the limiting grooves 25 inside the two connecting blocks 22. By repeatedly pulling and pushing the round rod, the two connecting blocks 22 can drive the sliding block 26 and the piston plate 28 to move repeatedly inside the cavity. With the help of the preset air inlet at the bottom of the movable block 10, when the piston plate 28 moves in the cavity toward the direction close to the rectangular groove 29, the external air can be sucked into the cavity through the air inlet. When the piston plate 28 moves in the cavity toward the direction away from the rectangular groove 29, the air inside the cavity can be discharged through the two round holes 2 3 and two air delivery pipes 20 to the inside of the airbag 9, so that the airbag 9 can be inflated and expanded as the gas delivered by the two air delivery pipes 20 increases, and after the airbag 9 is expanded to a specified state, the telescopic ends of the two electric telescopic rods 27 are controlled to push the piston plate 28 to move to the position of the two circular holes 23, so that the two circular holes 23 are blocked, thereby preventing the gas inside the airbag 9 from flowing back into the cavity. Then, when the display screen body 1 is installed, the airbag 9 in the inflated and expanded state can block the connection gap between the display screen body 1 and the box body 2 inside the box body 2, thereby improving the dustproof and waterproof performance of the box body 2.

[0048] At the same time, when the display screen body 1 is installed on the front side of the box body 2 and is used, if the air inside the airbag 9 is lost, the connection between the airbag 9 and the display screen body 1 and the box body 2 may not be close enough, thereby reducing the dust and water resistance of the box body 2. At this time, the telescopic ends of the two electric telescopic rods 27 can be controlled to continuously telescope inside the cavity, driving the piston plate 28 to continue to move slightly inside the cavity, and the sucked air is transported to the inside of the airbag 9 again, so as to achieve the effect of automatically replenishing the air in the airbag 9, thereby avoiding the problem that the airbag 9 cannot maintain effective sealing of the connection between the box body 2 and the display screen body 1 when used for a long time.

[0049] If the display screen body 1 is damaged during use and needs to be disassembled and replaced, the telescopic ends of the two electric telescopic rods 27 inside the two movable blocks 10 are controlled to retract, driving the piston plate 28 to move to a state of abutment with one end of the sliding block 26. Then, the front of the display screen body 1 can be adsorbed with the help of an adsorption tool, driving the display screen body 1 to move a distance away from the box body 2, so that the multiple first magnets 3 and the second magnets 7 are in contact with each other and the multiple guide rods 8 are moved outward from the inside of the corresponding guide grooves 4, and at the same time, the sliding block 26 is pulled outward from the inside of the rectangular groove 29 to move a distance, so that a gap is left between the display screen body 1 and the box body 2. At this time, the two limit plates 30 can be controlled to rotate downward in the direction close to the electric telescopic rod 27 so that they no longer abut the sliding block 26. The moving distance of the block 26 is limited, and the telescopic ends of the two electric telescopic rods 27 are synchronously controlled to extend to the maximum length. As the display screen body 1 is manually driven to move in the direction away from the box body 2, the sliding block 26 is driven to move outward from the inside of the rectangular groove 29, so that the distance between the display screen body 1 and the box body 2 is further expanded. At this time, the pull rod 6 can be pulled upward manually or with the help of tools, which drives the two connecting rods 11 to rotate in the direction of approaching each other, and pulls the two limit blocks 16 to move in the direction of approaching each other, so that the two limit blocks 16 are respectively moved out of the corresponding limit grooves 25, and with the help of the limit fixation between the two connecting blocks 22 and the connecting grooves 14, the display screen body 1 can be removed from the front of the box body 2, which is convenient for replacing a new display screen body 1.

[0050] When a small number of display screen bodies 1 need to be transported to the installation location, in order to avoid damage to the display screen bodies 1, the two movable blocks 10 on the back of the multiple display screen bodies 1 can be controlled to rotate to a state parallel to the display screen bodies 1, and then the multiple airbags 9 are controlled to inflate and slightly unfold in turn, and then they are stacked in turn, so that the multiple display screen bodies 1 are blocked by the unfolded airbags 9, avoiding the problem of directly stacking them and causing damage to the front of the display screen body 1; because the airbag 9 is located between two adjacent display screen bodies 1, it can also have a buffering effect on the vibration generated during transportation, avoiding the problem of two adjacent display screen bodies 1 rubbing against each other, which will have an adverse effect on the subsequent use of the display screen body 1.

[0051] At the same time, if no fixing belt or other strapping tools are brought along, to fix multiple display screen bodies 1, the airbags 9 on the back of two of the display screen bodies 1 can be inflated so that the two airbags 9 are inflated and expanded to their maximum state, and then the other display screen bodies 1 can be placed in turn inside the expanded airbags 9 of the two display screen bodies 1, and the two airbags 9 can be connected and fixed by means of connecting ropes 21, thereby facilitating the transportation of a small number of display screen bodies 1 and ensuring the safety of the display screen bodies 1 during transportation.

[0052] If a large number of display screen bodies 1 need to be transported, the transport equipment will be equipped with relevant fixing belts or other bundling tools to bundle and fix them. At this time, the airbags 9 on the back of the multiple display screen bodies 1 can be controlled to inflate in turn, and then folded toward the front of the display screen body 1, so that the inflated airbags 9 can wrap and protect the four corners of the display screen body 1, avoiding the corners of the display screen body 1 from colliding with other objects or other display screen bodies 1 during the bundling and transportation of the multiple display screen bodies 1, which may cause damage to the display screen body 1, thereby further improving the protection effect of the multiple display screen bodies 1 during transportation.

[0053] The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well. The present invention is limited only by the claims and their full scope and equivalents.
