[0012] Preferably, the connecting mechanism comprises a positioning block and a plug-in block, the positioning block is movably mounted on the top of the box body and the rotating block on one side, and the plug-in block is movably mounted on the bottom of the box body and the rotating block on the other side.

[0013] Preferably, a first electric telescopic rod is installed on a side of the positioning block close to the rotating block, the mounting end of the first electric telescopic rod is away from the positioning block, and the first electric telescopic rod is embedded and installed in the interior of the rotating block, and a second electric telescopic rod is installed on an end of the plug-in block close to the rotating block, the mounting end of the second electric telescopic rod is away from the plug-in block, and an end of the second electric telescopic rod close to the rotating block is embedded and installed in the interior of the rotating block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing a rotating block, a positioning block and a plug-in block, if the size of the LED screen needs to be replaced, the first electric telescopic rod and the second electric telescopic rod are extended to a preset position. This operation method can change the distance between multiple box bodies. Then the staff removes the LED screen originally installed on the box body and installs the large-size LED screen that needs to be replaced on the box body. This operation method allows the box body to adapt to the use of LED screens of various sizes, thereby increasing the functional applicability and convenience of the device. When the box bodies need to be spliced, the positioning blocks and the plug-in blocks are both extended to the preset positions. At this time, the staff aligns the positioning blocks on the two box bodies with the plug-in blocks for splicing. The plug-in blocks are plugged into the positioning grooves. During the plug-in process, the circular blocks will squeeze the third spring telescopic rod. When the circular blocks are plugged into the circular grooves, the installation of the positioning blocks and the plug-in blocks is completed. Multiple box bodies can be quickly assembled in this installation method. When the box body needs to be transported and transferred, the rotating block is driven to rotate by the rotating motor. The rotated positioning blocks and the plug-in blocks are horizontally oriented to the two sides of the box body. The first electric telescopic rod and the second electric telescopic rod drive the positioning blocks and the plug-in blocks to extend to the preset positions. Then the staff will place the two box bodies in a parallel manner with one side aligned with the other side. At this time, the positioning block on one box body is aligned with the plug-in block on the other box body. The staff will plug and install the plug-in block into the positioning block to fix the two box bodies. This installation method can fix multiple box bodies into a whole, so that the box body can be more stable during transportation and transfer. This splicing method can also protect the electric equipment on the box body, which increases the convenience of using the device. During the process of assembling the LED screen for use, if one side of the LED screen or one side of the box body is hit, the impact force on the LED screen or the box body will directly act on the box body, and because the box body is spliced, the impact force at this time will cause the impacted box body to move. During the movement of the box body, the second spring telescopic rod is squeezed, and the absorption of the impact force by the second spring telescopic rod can achieve the effect of absorbing the impact force, thereby achieving a shock-absorbing effect on the box body and the LED screen. Through this operation method, the LED screen or the box body can be buffered when it is impacted, reducing the damage to the device when it is impacted, and increasing the safety of the device.

[0016] The present invention is provided with an annular guide rail, a movable block and a first spring telescopic rod. During the installation of the LED screen, when the plug-in assembly on the LED screen is plugged into the connecting piece, the annular guide rail is extended by the first electric extension rod, so that the plurality of first spring telescopic rods abut against the back of the LED screen. Then the first electric extension rod drives the annular guide rail to retract. The staff presses the LED screen and plugs the plug-in assembly on the LED screen into the inside of the connecting piece while ensuring that the LED screen abuts against the first spring telescopic rod, so that the plug-in assembly on the LED screen can be plugged into the connecting piece more smoothly. This installation method can prevent the staff from causing excessive friction between the plug-in assembly on the LED screen when the plug-in assembly is plugged into the connecting piece due to irregular operations during the installation process, such as incorrect plug-in angles. This will reduce the service life of the connecting piece in the long run. This operation method can ensure the stability of the use of the connecting piece and its normal service life. After the LED screen and the box body are installed, the annular guide rail is used to move close to the LED screen, so that the first spring telescopic rod squeezes the LED screen. When the first spring telescopic rod squeezes the LED screen, the first spring telescopic rod squeezes the pressure sensor, and the pressure sensor transmits the measured pressure value to the background control system. When the first spring telescopic rod continues to squeeze the LED screen, the pressure value measured by the pressure sensor reaches a preset pressure value. At this time, the installation status of the LED screen and the box body is observed. Through this operation method, the installation stability of the LED screen can be detected, thereby increasing the use stability of the device. The annular guide rail is moved close to the LED screen so that the first spring telescopic rod abuts the LED screen. At this time, the first spring telescopic rod squeezes the pressure sensor, and the pressure sensor transmits the measured pressure value to the background control system. Then, the first driving slider slides in the annular guide rail so that the connecting rod moves along a preset trajectory on the annular guide rail. Combined with the sliding of the first electric slider in the first slide groove, the movable block and the first spring telescopic rod can move to a preset use position according to demand. Then, when the first spring telescopic rod abuts against different positions of the LED screen, the background control system compares the pressure values ​​measured by the pressure sensor, thereby monitoring the flatness of the connection of the LED screen to prevent the LED screen from being deformed and affecting the normal use and installation stability of the LED screen. When a certain LED screen needs to be replaced during use, the box body connected to the LED screen performs the following operations: the annular guide rail moves close to the LED screen, and the first spring telescopic rod squeezes the LED screen. Under the continuous squeezing of the first spring telescopic rod, the connection of the LED screen is separated from the connecting part. At this time, the staff can remove the LED screen for replacement. Through this operation method, the convenience of disassembly of the LED screen by the staff is increased.

[0021] As a technical optimization solution of the present invention, a plurality of first electric extension rods 9 are evenly embedded and installed at the bottom end of the inner wall of the first slot 3, and the telescopic ends of the first electric extension rods 9 face the annular guide rail 5, and the telescopic ends of the first electric extension rods 9 are connected to the annular guide rail 5. The first electric extension rods 9 can drive the annular guide rail 5 to move, so that the annular guide rail 5 can switch the use state according to the use requirements.

[0022] As a technical optimization solution of the present invention, the detection mechanism includes a connecting rod 6, a movable block 13 and a first spring telescopic rod 14. A plurality of connecting rods 6 are evenly and movably installed on the side of the annular guide rail 5 away from the first electric extension rod 9. A movable block 13 is movably installed on the side of the connecting rod 6 away from the annular guide rail 5. The first spring telescopic rod 14 is movably installed on one end of the movable block 13 away from the connecting rod 6. During the installation of the LED screen, when the plug-in component on the LED screen is plugged into the connector 4, the annular guide rail 5 is extended by the first electric extension rod 9, so that the multiple first spring telescopic rods 14 abut against the back of the LED screen. Then the first electric extension rod 9 drives the annular guide rail 5 to retract. The staff presses the LED screen and plugs the plug-in component on the LED screen into the interior of the connector 4 while ensuring that the LED screen abuts against the first spring telescopic rod 14, so that the process of plugging the plug-in component on the LED screen into the connector 4 can be smoother. This installation method can prevent the staff from operating the LED screen improperly during the installation process, such as incorrect plugging angle, which causes excessive friction between the two when the plug-in component on the LED screen is plugged into the connector 4, which will reduce the service life of the connector 4 in the long run. This operation method can ensure the stability of use and the normal service life of the connector 4.

[0023] As a technical optimization scheme of the present invention, a first driving slider 10 is installed on the side of the connecting rod 6 close to the annular guide rail 5, and the first driving slider 10 is slidably installed inside the annular guide rail 5. A first slide groove 11 is provided on the side of the connecting rod 6 away from the annular guide rail 5, and a first electric slider 12 is installed on the end of the movable block 13 close to the connecting rod 6, and the first electric slider 12 is slidably installed inside the first slide groove 11. A third slot 15 is provided on the end of the movable block 13 away from the connecting rod 6, and a pressure sensor 16 is installed on the bottom end of the inner wall of the third slot 15. The end of the first spring telescopic rod 14 close to the movable block 13 is slidably installed inside the third slot 15, and the end of the first spring telescopic rod 14 close to the pressure sensor 16 is in contact with the pressure sensor 16. After the LED screen and the box body 1 are installed, the annular guide rail 5 is moved close to the LED screen, so that the first spring telescopic rod 14 squeezes the LED screen. When the first spring telescopic rod 14 squeezes the LED screen, the first spring telescopic rod 14 squeezes the pressure sensor 16. The pressure sensor 16 transmits the measured pressure value to the background control system. When the first spring telescopic rod 14 continues to squeeze the LED screen, the pressure value measured by the pressure sensor 16 reaches the preset pressure value. At this time, the installation status of the LED screen and the box body 1 is observed. Through this operation method, the installation stability of the LED screen can be detected, thereby increasing the use stability of the device. After the LED screen has been used for a long time or has been impacted, the annular guide rail 5 moves closer to the LED screen, so that the first spring telescopic rod 14 abuts against the LED screen. At this time, the first spring telescopic rod 14 squeezes the pressure sensor 16, and the pressure sensor 16 transmits the measured pressure value to the background control system. Subsequently, the first driving slider 10 slides in the annular guide rail 5, so that the connecting rod 6 moves along a preset trajectory on the annular guide rail 5. Combined with the sliding of the first electric slider 12 in the first slide groove 11, the movable block 13 and the first spring telescopic rod 14 can move to the preset use position according to demand. Subsequently, when the first spring telescopic rod 14 abuts against different positions of the LED screen, the background control system compares the pressure values ​​measured by the pressure sensor 16, so that the flatness of the connection of the LED screen can be monitored to prevent the LED screen from being deformed and affecting the normal use and installation stability of the LED screen.

[0024] As a technical optimization solution of the present invention, a fourth slot 17 is horizontally provided on both side walls of the second slot 7, and a rotating motor 19 is movably installed inside the fourth slot 17, and the output end of the rotating motor 19 faces the rotating block 8, and the output end of the rotating motor 19 is connected to the rotating block 8. The rotating block 8 can be driven to rotate by the rotating motor 19, so that the rotating block 8 can be converted into a use state according to the use requirements, which increases the convenience of use of the device.

[0025] As a technical optimization solution of the present invention, a stable slide groove 18 is provided on both side walls of the fourth slot 17, and a stable slider 21 is slidably installed inside the stable slide groove 18, and one end of the stable slider 21 close to the rotating motor 19 is connected to the rotating motor 19. By sliding the stable slider 21 in the stable slide groove 18, the movement of the rotating motor 19 in the fourth slot 17 can be more stable, thereby increasing the stability of the device in use.

[0026] As a technical optimization solution of the present invention, a second spring telescopic rod 20 is installed on both end walls of the fourth slot 17, and one end of the second spring telescopic rod 20 close to the rotating motor 19 is connected to the rotating motor 19. If one side of the LED screen or one side of the box body 1 is hit, the impact force on the LED screen or the box body 1 will directly act on the box body 1, and because the box body 1 is spliced, the impact force at this time will cause the impacted box body 1 to move. During the movement of the box body 1, the second spring telescopic rod 20 is squeezed. The absorption of the impact force by the second spring telescopic rod 20 can achieve the effect of absorbing the impact force, thereby achieving the shock absorbing effect on the box body 1 and the LED screen. Through this operation mode, the LED screen or the box body 1 can be buffered when it is impacted, reducing the damage to the device when it is impacted, and increasing the safety of the device.

[0027] As a technical optimization solution of the present invention, the connection mechanism includes a positioning block 22 and a plug-in block 26. The positioning block 22 is movably installed on the top of the box body 1 and the rotating block 8 on one side, and the plug-in block 26 is movably installed on the bottom of the box body 1 and the rotating block 8 on the other side. When the box bodies 1 are spliced, the plug-in block 26 can be plugged into the positioning block 22 to achieve rapid installation between multiple box bodies 1.

[0028] As a technical optimization scheme of the present invention, a first electric telescopic rod 25 is installed on the side of the positioning block 22 close to the rotating block 8, the installation end of the first electric telescopic rod 25 is far away from the positioning block 22, and the first electric telescopic rod 25 is embedded and installed in the interior of the rotating block 8, and a second electric telescopic rod 28 is installed on the end of the plug-in block 26 close to the rotating block 8, the installation end of the second electric telescopic rod 28 is far away from the plug-in block 26, and the end of the second electric telescopic rod 28 close to the rotating block 8 is embedded and installed in the interior of the rotating block 8. When the LED screen is installed, if the size of the LED screen needs to be replaced, it is only necessary to control the first electric telescopic rod 25 and the second electric telescopic rod 28 to extend to the preset position through the background control system. Through this operation mode, the distance between multiple box bodies 1 can be changed, and then the staff will remove the LED screen originally installed on the box body 1, and then install the large-size LED screen that needs to be replaced on the box body 1. Through this operation mode, the box body 1 can adapt to LED screens of various sizes for use, which increases the functional applicability and convenience of the device.

[0029] As a technical optimization solution of the present invention, a positioning groove 23 is provided on the side of the positioning block 22 away from the rotating block 8, and circular grooves 24 are provided on the inner walls of both sides of the positioning groove 23. Displacement grooves 29 are provided on both sides of the plug-in block 26, and a third spring telescopic rod 30 is installed inside the displacement groove 29. A circular block 27 is installed at one end of the two third spring telescopic rods 30 away from each other. The plug-in block 26 can be plugged into the inside of the positioning groove 23, and the circular block 27 can be snapped into the inside of the circular groove 24. When the plug-in block 26 is plugged into the positioning block 22, the circular block 27 will squeeze the third spring telescopic rod 30, causing the third spring telescopic rod 30 to shrink. At this time, the circular block 27 enters the inside of the displacement groove 29. When the circular block 27 moves to the circular groove 24, the circular block 27 is pushed by the third spring telescopic rod 30 and snapped into the inside of the circular groove 24. At this time, the installation of the positioning block 22 and the plug-in block 26 is completed, which can increase the installation stability of the plug-in block 26 and the positioning block 22.

[0030] When the present invention is in use, multiple box bodies 1 are combined into a large device by splicing, the electric drive device on the box body 1 is powered by an external power supply, and the device controls the electric drive device on the device by setting a background control system.

[0031] When the box body 1 needs to be spliced, the staff can energize the box body 1 in a pre-energized manner, so that the first electric telescopic rod 25 and the second electric telescopic rod 28 are extended, and the positioning block 22 and the plug-in block 26 are both extended to the preset position. Then the staff cuts off the power to the box body 1. At this time, the staff aligns the positioning blocks 22 on the two box bodies 1 with the plug-in blocks 26, and the plug-in blocks 26 are plugged into the positioning grooves 23. During the plug-in process of the plug-in blocks 26, the circular blocks 27 squeeze the third spring telescopic rod 30, so that the third spring telescopic rod 30 contracts. At this time, the circular block 27 enters the interior of the displacement groove 29. When the circular block 27 moves to the circular groove 24, the circular block 27 is pushed by the third spring telescopic rod 30 and the circular block 27 is snapped into the interior of the circular groove 24. At this time, the installation of the positioning block 22 and the plug-in block 26 is completed. Through this installation method, multiple box bodies 1 can be quickly assembled, and then the box body 1 can be energized; After the assembly of multiple box bodies 1 is completed, the assembled box bodies 1 are fixed by a preset fixing frame. A component that can be connected to the connector 4 is provided on one side where the LED screen and the box body 1 are assembled, and the connection method between the two is a plug-in installation method. The plug-in method between the two is an existing mature technology, so it will not be elaborated on in detail. The electrical connection method between the LED screen and the box body 1 is an existing mature technology, so it will not be elaborated on in detail. The staff connects the LED screen to the box body 1 through the connector 4, and the magnet 2 will adsorb the LED screen. At this time, the installation of the LED screen is completed; During the installation of the LED screen, when the plug-in component on the LED screen is plugged into the connecting piece 4, the annular guide rail 5 is extended by the first electric extension rod 9, so that the multiple first spring telescopic rods 14 abut against the back of the LED screen. Then the first electric extension rod 9 drives the annular guide rail 5 to retract, and the staff presses the LED screen, and plugs the plug-in component on the LED screen into the inside of the connecting piece 4 while ensuring that the LED screen abuts against the first spring telescopic rod 14, so that the process of plugging the plug-in component on the LED screen into the connecting piece 4 can be smoother, and the multiple first spring telescopic rods 14 guide and limit the movement of the LED screen. This installation method can prevent the staff from operating improperly during the installation process, such as incorrect plugging angle, which causes excessive friction between the plug-in components on the LED screen when they are plugged into the connecting piece 4, which will reduce the service life of the connecting piece 4 in the long run. This operation method can ensure the stability of use and the normal service life of the connecting piece 4.

[0032] After the LED screen and the box body 1 are installed, the annular guide rail 5 is moved close to the LED screen, so that the first spring telescopic rod 14 squeezes the LED screen. When the first spring telescopic rod 14 squeezes the LED screen, the first spring telescopic rod 14 squeezes the pressure sensor 16. The pressure sensor 16 transmits the measured pressure value to the background control system. When the first spring telescopic rod 14 continues to squeeze the LED screen, the pressure value measured by the pressure sensor 16 reaches a preset pressure value. At this time, the installation status of the LED screen and the box body 1 is observed. Through this operation method, the installation stability of the LED screen can be detected, thereby increasing the stability of the device.

[0033] When the LED screen is installed, if the size of the LED screen needs to be changed, it is only necessary to control the first electric telescopic rod 25 and the second electric telescopic rod 28 to extend to the preset position through the background control system. This operation method can change the distance between multiple box bodies 1. Then the staff will remove the LED screen originally installed on the box body 1, and install the large-size LED screen that needs to be replaced on the box body 1. Through this operation method, the box body 1 can adapt to LED screens of various sizes for use, which increases the functional applicability and convenience of the device.

[0034] During the process of assembling and using the LED screen, if one side of the LED screen or one side of the box body 1 is hit, the impact force on the LED screen or the box body 1 will directly act on the box body 1, and because the box body 1 is spliced, the impact force at this time will cause the impacted box body 1 to move. During the movement of the box body 1, the second spring telescopic rod 20 is squeezed. The absorption of the impact force by the second spring telescopic rod 20 can achieve the effect of absorbing the impact force, thereby achieving a shock absorbing effect on the box body 1 and the LED screen. Through this operation method, the LED screen or the box body 1 can be buffered when it is impacted, reducing the damage to the device when it is impacted, and increasing the safety of the device.

[0035] After the LED screen has been used for a long time or has been impacted, the annular guide rail 5 moves closer to the LED screen, so that the first spring telescopic rod 14 abuts against the LED screen. At this time, the first spring telescopic rod 14 squeezes the pressure sensor 16, and the pressure sensor 16 transmits the measured pressure value to the background control system. Subsequently, the first driving slider 10 slides in the annular guide rail 5, so that the connecting rod 6 moves along a preset trajectory on the annular guide rail 5. Combined with the sliding of the first electric slider 12 in the first slide groove 11, the movable block 13 and the first spring telescopic rod 14 can move to the preset use position according to demand. Subsequently, when the first spring telescopic rod 14 abuts against different positions of the LED screen, the background control system compares the pressure values ​​measured by the pressure sensor 16, so that the flatness of the connection of the LED screen can be monitored to prevent the LED screen from being deformed and affecting the normal use and installation stability of the LED screen.

[0036] When a certain LED screen needs to be replaced during use, the box body 1 connected to the LED screen performs the following operation: the annular guide rail 5 moves close to the LED screen, and the first spring telescopic rod 14 squeezes the LED screen. Under the continuous squeezing of the first spring telescopic rod 14, the connection of the LED screen is separated from the connecting piece 4. At this time, the staff can remove the LED screen for replacement. Through this operation method, the convenience of disassembly of the LED screen by the staff is increased.

[0037] When the box body 1 needs to be transported and transferred, the rotating block 8 is driven to rotate by the rotating motor 19, so that the two positioning blocks 22 and the plug-in blocks 26 on each side of the box body 1 are rotated to opposite directions, and the rotated positioning blocks 22 and the plug-in blocks 26 are horizontally oriented to the two sides of the box body 1, and the positioning blocks 22 and the plug-in blocks 26 are driven to extend to the preset positions by the first electric telescopic rod 25 and the second electric telescopic rod 28. Then the staff puts the two box bodies 1 in a parallel manner with one side aligned with the other side. At this time, the positioning block 22 on one box body 1 is aligned with the plug-in block 26 on the other box body 1. The staff plugs the plug-in block 26 into the positioning block 22 to fix the two box bodies 1. This installation method can fix multiple box bodies 1 into a whole, so that the box body 1 can be more stable during transportation and transfer. This splicing method can also protect the electric equipment on the box body 1, increasing the convenience of use of the device.
