[0045] See also Figures 1 to 3 The embodiment of the present application proposes a connecting device 100 for connecting two adjacent LED display screens 1000, including a fixing seat 10, a rotating assembly 20, a hook locking member 30 and a linkage locking rod assembly 40.

[0046] The fixing base 10 can be detachably connected to the LED display screen 1000 .

[0047] The fixing seat 10 can be a seat structure such as a base, a pedestal, etc. The fixing seat 10 is used to provide a stable installation position for the rotating assembly 20 .

[0048] As an example, the fixing base 10 can be detachably connected to the LED display screen 1000 by means of a threaded connection. As another example, the fixing base 10 can be detachably connected to the LED display screen 1000 by means of a buckle structure.

[0049] The rotating assembly 20 is rotatably connected to the fixing base 10 , and the rotating assembly 20 has a locked state and an unlocked state.

[0050] The rotating assembly 20 can be rotatably connected to the fixing base 10 by means of a shaft-hole fit. Figure 1 As shown, the connecting device 100 includes a rotating shaft assembly, and shaft holes adapted to the rotating shaft assembly are respectively provided on the rotating shaft assembly 20 and the fixed seat 10. When installed, the rotating shaft assembly sequentially passes through the shaft holes on the fixed seat 10 and the rotating shaft assembly 20. The rotating shaft assembly 20 is rotatably connected to the fixed seat 10 through the rotating shaft assembly, and the rotating shaft assembly 20 can rotate relative to the fixed seat 10 within a certain angle.

[0051] The locked state and the unlocked state are two assembly positions when the rotating assembly 20 rotates relative to the fixing seat 10 .

[0052] The hook lock 30 is used to lock or unlock two adjacent LED display screens 1000. The hook lock 30 is connected to the rotating component 20. The hook lock 30 and the rotating component 20 are configured to drive the hook lock 30 to lock or unlock two adjacent LED display screens 1000 when the rotating component 20 is switched to a locked state or an unlocked state.

[0053] The hook lock member 30 can be a claw, a hook or other structures.

[0054] The number of the hook lock member 30 can be one or more. Figure 1 As shown, the connecting device 100 includes two hook locking members 30 .

[0055] When splicing a large LED screen, at the connection position of two adjacent LED display screens 1000, one of the LED display screens 1000 includes a connecting device 100, and the other LED display screen 1000 is provided with a connecting structure 200 adapted to the hook locking member 30, and the shape and size of the connecting structure 200 are adapted to the shape and size of the hook locking member 30, and the hook locking member 30 can be snapped and fixed to the connecting structure 200, and tighten the gap between the two adjacent LED display screens 1000 to lock the two adjacent LED display screens 1000.

[0056] The hook lock member 30 is rotatably connected to the rotating assembly 20. For example, Figure 1 As shown, the hook lock member 30 is rotatably connected to the rotating assembly 20 by means of shaft-hole matching.

[0057] like Figure 4 and Figure 5 As shown, the hook lock member 30 can freely rotate relative to the rotating assembly 20 within a certain angle.

[0058] The locking and releasing functions of the hook lock 30 correspond to the locking state and unlocking state of the rotating assembly 20. When the rotating assembly 20 rotates around the fixing base 10 to the locking state, the hook lock 30 is driven by the rotating assembly 20 to lock the two adjacent LED display screens 1000; when the rotating assembly 20 rotates around the fixing base 10 to the unlocking state, the hook lock 30 is driven by the rotating assembly 20 to unlock the two adjacent LED display screens 1000.

[0059] The interlocking lock rod assembly 40 is connected to the rotating assembly 20, and the interlocking lock rod assembly 40 has a clamping state and a releasing state. The interlocking lock rod assembly 40 and the rotating assembly 20 are configured so that when the rotating assembly 20 is switched to a locked state or an unlocked state, the interlocking lock rod assembly 40 switches to a clamping state or a releasing state, so as to lock or release the rotating assembly 20 on the fixed seat 10.

[0060] The linkage lock rod assembly 40 is a structure for clamping the rotating assembly 20 to the fixing seat 10. For example, a latch, a buckle, a screw, etc.

[0061] The clamping state and the releasing state are two assembly positions of the linkage lock rod assembly 40 moving relative to the fixing seat 10 .

[0062] The clamping state corresponds to the locking state of the rotating assembly 20. When the rotating assembly 20 is switched to the locking state, the linkage locking rod assembly 40 can be switched to the clamping state to lock the rotating assembly 20 to the fixing seat 10.

[0063] The release state corresponds to the unlocked state of the rotating assembly 20. When the rotating assembly 20 needs to be switched to the unlocked state, the linkage lock rod assembly 40 can be switched to the release state, releasing the clamping connection between the rotating assembly 20 and the fixing seat 10, so that the rotating assembly 20 can rotate relative to the fixing seat 10 to switch to the unlocked state.

[0064] When splicing the LED display screens 1000, first connect the hook lock member 30 to the connecting structure 200 of the adjacent LED display screens 1000, and then drive the rotating assembly 20 to rotate around the fixing seat 10 to a locked state. During the rotation process, the rotating assembly 20 drives the hook lock member 30 to tighten the gap between the two adjacent LED display screens 1000, so that the contact parts of the two are tightly fitted. At the same time, the linkage lock rod assembly 40 switches to a clamping state to fix the rotating assembly 20 to the fixing seat 10. Due to the clamping effect of the linkage lock rod assembly 40, the rotating assembly 20 is always in a locked state, and the two adjacent LED display screens 1000 are tightly connected.

[0065] When disassembling the LED display screen 1000, first switch the interlocking lock rod assembly 40 to the released state to release the clamping connection between the rotating assembly 20 and the fixed seat 10, so that the rotating assembly 20 can rotate relative to the fixed seat 10, and then drive the rotating assembly 20 to rotate around the fixed seat 10 to the unlocked state. During the rotation process, the tension between the rotating assembly 20 and the hook lock member 30 disappears, and the hook lock member 30 can rotate freely relative to the rotating assembly 20. Rotate the hook lock member 30 in a direction away from the connecting structure 200 to release the connection between the two adjacent LED display screens 1000.

[0066] In the connection device 100 provided in the embodiment of the present application, the fixed base 10 can provide a stable connection for the rotating component 20; by the rotating component 20 rotating around the fixed base 10, it can drive the hook lock 30 to lock or unlock two adjacent LED display screens 1000; the rotating component 20 can be clamped to the fixed base 10 through the interlocking lock rod assembly 40; through the double locking of the interlocking lock rod assembly 40 and the hook lock 30, when unlocking two adjacent LED display screens 1000, the interlocking lock rod assembly 40 and the hook lock 30 need to be unlocked and released at the same time, which can avoid unlocking due to accidental touching of the interlocking lock rod assembly 40 or the rotating component 20 during operation or use, which helps to improve the reliability and safety of the LED display screen 1000; in addition, the operator only needs to flip the rotating component 20 to quickly realize the splicing of the LED display screen 1000, which is convenient to operate and helps to improve the splicing efficiency.

[0067] like Figure 1 and Figure 6 As shown, in some embodiments, the interlocking lock rod assembly 40 includes a limit member 41, and a limit hole 11 adapted to the limit member 41 is opened on the fixed seat 10. The limit member 41 can be inserted into or removed from the limit hole 11 to realize the switching of the interlocking lock rod assembly 40 to a clamped state or a released state.

[0068] The limiting member 41 may be a mounting structure such as a pin, a latch, or a screw.

[0069] The limiting hole 11 is a through hole, a blind hole or the like.

[0070] The shape and size of the limiting hole 11 are adapted to the shape and size of the limiting member 41. Exemplarily, the diameter of the limiting hole 11 is the same as the diameter of the limiting member 41.

[0071] Optionally, in order to enable the limiting member 41 to be easily inserted into or removed from the limiting hole 11 , the size of the limiting hole 11 may be slightly larger than the size of the limiting member 41 .

[0072] The limiting member 41 can be inserted into or removed from the limiting hole 11 in a variety of ways. For example, the limiting member 41 can be connected to the output end of the electric cylinder or the air cylinder, and the limiting member 41 is driven by the electric cylinder or the air cylinder to be inserted into or removed from the limiting hole 11. For example, the limiting member 41 can be a lead screw, and the limit member 41 is driven by a ball screw to be inserted into or removed from the limiting hole 11.

[0073] When in use, when the rotating assembly 20 rotates around the fixed seat 10 to the locked state, the rotating assembly 20 is linked with the limiting member 41 to move to align with the limiting hole 11, and the limiting member 41 is inserted into the limiting hole 11, so that the linkage lock rod assembly 40 is switched to the clamped state, and the rotating assembly 20 is fixed to the fixed seat 10. When the rotating assembly 20 needs to be switched to the unlocked state, the limiting member 41 moves out of the limiting hole 11, so that the linkage lock rod assembly 40 is switched to the released state, and the fixed connection between the rotating assembly 20 and the fixed seat 10 is released, and the rotating assembly 20 can rotate relative to the fixed seat 10 and switch to the unlocked state.

[0074] By adopting the above-mentioned technical scheme, when the limit member 41 is inserted into the limit hole 11, the limit member 41 is clamped with the fixing seat 10, and the interlocking lock rod assembly 40 can be effectively fixed on the fixing seat 10; when the limit member 41 moves out of the limit hole 11, the fixing seat 10 releases the interlocking lock rod assembly 40, and the interlocking lock rod assembly 40 can move freely; through the cooperation between the limit member 41 and the limit hole 11, it can be ensured that the connection between the limit member 41 and the fixing seat 10 is firm and reliable, and the operation is simple and convenient, which helps to enhance the stability and safety of the connecting device 100.

[0075] In some embodiments, the linkage lock rod assembly 40 includes a linkage rod 42 and a limit member 41 connected to the linkage rod 42. The linkage rod 42 is rotatably connected to the rotating assembly 20. The linkage rod 42 and the limit member 41 are configured so that when the linkage rod 42 rotates around its own axis, the limit member 41 is driven by the linkage rod 42 to be inserted into or moved out of the limit hole 11.

[0076] The linkage rod 42 is a rod-shaped, strip-shaped or other connecting rod structure.

[0077] The stopper 41 is rotatably connected to the linkage rod 42. Exemplarily, the stopper 41 is hinged to the linkage rod 42. Exemplarily, the stopper 41 is connected to the linkage rod 42 by a pin connection.

[0078] like Figure 1 and Figure 7 As shown, in order to prevent the limiting member 41 and the linkage rod 42 from getting stuck, a strip groove may be provided on the linkage rod 42. When the linkage rod 42 rotates around its own axis, the limiting member 41 can move along the groove wall of the strip groove.

[0079] The rotating assembly 20 is provided with a rotating hole matched with the linkage rod 42, and the linkage rod 42 rotates around its own axis in the rotating hole.

[0080] When in use, by rotating the linkage rod 42 , the limiting member 41 can be driven to be inserted into or moved out of the limiting hole 11 , thereby realizing the switching between the clamping state and the releasing state of the linkage lock rod assembly 40 .

[0081] In this embodiment, the state of the limit member 41 can be controlled by rotating the linkage rod 42, driving the limit member 41 to be accurately inserted into or moved out of the limit hole 11, thereby quickly switching the linkage lock rod assembly 40 to a clamped state or a released state. The operation is simple and efficient, and can ensure the reliability and stability of the linkage rod 42 assembly.

[0085] The pressing portion 422 is disposed on the main body 421 . When an external force is applied to the pressing portion 422 , the pressing portion 422 can drive the main body 421 to rotate around its own axis.

[0086] The stopper 41 is rotatably connected to the main body 421. Exemplarily, the stopper 41 is hinged to the main body 421. Exemplarily, the stopper 41 is connected to the main body 421 by a pin connection.

[0087] When the pressing portion 422 is pressed, the main body 421 rotates around its own axis driven by the pressing portion 422 , and the limiting member 41 is inserted into or moved out of the limiting hole 11 driven by the main body 421 .

[0088] Optionally, a torsion spring may be provided at the connection position between the pressing portion 422 and the main body 421, the torsion spring being sleeved on the main body 421, with one end of the torsion spring abutting against the pressing portion 422, and the other end abutting against the rotating assembly 20. When the pressing portion 422 is pressed, the torsion spring deforms and stores elastic potential energy, so that when the operator presses the pressing portion 422, a pressing feedback can be obtained, and when the operator releases the pressing portion 422, the torsion spring can drive the pressing portion 422 to automatically rebound.

[0089] In this embodiment, by applying pressure to the pressing portion 422, the main body 421 can be driven to rotate around its own axis, so that the limiting member 41 is inserted into or moved out of the limiting hole 11 under the drive of the main body 421, thereby realizing the clamping or releasing function of the interlocking lock rod assembly 40. The operation is simple and convenient, and the reliability and stability of the interlocking lock rod assembly 40 can be ensured.

[0092] The gripping portion 21 is used to provide a gripping space for an operator to flip the rotating assembly 20 . The operator can quickly switch the rotating assembly 20 between a locked state and an unlocked state by rotating the gripping portion 21 .

[0093] For example, Figure 1 As shown, the gripping portion 21 is rotatably connected to the fixing seat 10 by means of a pin connection. Exemplarily, the gripping portion 21 is hinged to the fixing seat 10.

[0094] The fixing portion 22 is a structure in the rotating assembly 20 that is connected to the hook lock member 30. The hook lock member 30 is rotatably connected to the fixing portion 22. For example, Figure 1 As shown, the hook lock member 30 can be rotatably connected to the fixing portion 22 by means of a pin connection.

[0095] In this embodiment, the holding portion 21 can provide a holding space for the operator, and the operator can realize the rotation of the entire rotating assembly 20 through the holding portion 21, which helps to quickly realize the switching of the rotating assembly 20 between the locked state and the unlocked state; the fixing portion 22 can provide a stable connection between the holding portion 21 and the hook lock 30, which helps to ensure the reliability and stability of the connecting device 100; the main body 421 is rotatably connected to the holding portion 21, so that the operator can control the rotation of the main body 421 while driving the rotating assembly 20, which helps to improve the convenience and efficiency of the operation; the hook lock 30 is rotatably connected to the fixing portion 22, which can effectively improve the compactness of the structure of the connecting device 100.

[0096] like Figure 1 and Figure 7 As shown, in some embodiments, the linkage lock rod assembly 40 further includes an elastic member 43 , which is sleeved on the limiting member 41 , one end of the elastic member 43 is connected to the limiting member 41 , and the other end of the elastic member 43 abuts against the fixing portion 22 .

[0097] The elastic member 43 can be a spring, rubber, elastic metal sheet or the like.

[0098] The elastic member 43 is sleeved on the limiting member 41. A boss can be set at one end where the limiting member 41 is connected to the elastic member 43. The diameter of the boss is larger than the diameter of the elastic member 43 to ensure that when the elastic member 43 is sleeved on the limiting member 41, the elastic member 43 will not slip off from this side of the boss under the action of external force.

[0099] When splicing the LED display screen 1000, the elastic member 43 is in its original state. The operator holds the gripping portion 21 and drives the gripping portion 21 to rotate toward the LED display screen 1000, and drives the interlocking lock rod assembly 40 to rotate at the same time, so that the limiting member 41 abuts against the fixing seat 10 and moves along the surface of the fixing seat 10 toward the limiting hole 11. At this time, the force of the fixing seat 10 on the limiting member 41 is transmitted to the elastic member 43, and the elastic member 43 is compressed and deformed. When the limiting member 41 moves to align with the limiting hole 11, the force of the fixing seat 10 on the limiting member 41 disappears, the elastic member 43 stretches to its original state, and drives the limiting member 41 to insert into the limiting hole 11, thereby realizing automatic locking of the limiting member 41.

[0100] When disassembling two adjacent LED display screens 1000, the pressing portion 422 drives the main body 421 to rotate around its own axis, and drives the limiting member 41 to move out of the limiting hole 11, thereby releasing the locking of the rotating component 20 by the limiting member 41, so that the rotating component 20 can rotate around the fixing seat 10 to an unlocked state, thereby realizing the unlocking of the two adjacent LED display screens 1000.

[0101] In this embodiment, during the process of the rotating component 20 switching from the unlocked state to the locked state, the limit member 41 abuts against the fixed seat 10, and the elastic member 43 is in a compressed state. When the rotating component 20 switches to the locked state, the limit member 41 is aligned with the limit hole 11, and the elastic member 43 releases the elastic potential energy to drive the limit member 41 to insert into the limit hole 11, so that the automatic locking of the limit member 41 can be achieved, which helps to improve the convenience and efficiency of operation.

[0102] like Figure 1 As shown, in some embodiments, the grip portion 21 includes a grip upper portion 211 and a grip lower portion 212 matched with the grip upper portion 211 , the grip upper portion 211 and the grip lower portion 212 enclose a receiving cavity 213 , and the main body 421 is disposed in the receiving cavity 213 .

[0103] The upper grip portion 211 and the lower grip portion 212 are two parts of the grip portion 21 that are arranged opposite to each other. The upper grip portion 211 and the lower grip portion 212 are detachably connected. Figure 1 As shown, the upper grip portion 211 is connected to the lower grip portion 212 by screws. Exemplarily, the upper grip portion 211 is connected to the lower grip portion 212 by a buckle structure.

[0104] When the upper grip portion 211 and the lower grip portion 212 are connected, the two enclose a receiving cavity 213. The shape and size of the receiving cavity 213 match those of the main body 421. When the main body 421 is accommodated in the receiving cavity 213, the main body 421 can rotate around its own axis along the cavity wall of the receiving cavity 213.

[0105] During installation, the main body 421 can be first installed on the upper grip part 211, and then the lower grip part 212 can be connected to the upper grip part 211, so that the main body 421 is enclosed in the accommodating cavity 213 formed by the upper grip part 211 and the lower grip part 212.

[0106] In this embodiment, the main body 421 is disposed in the accommodating cavity 213 enclosed by the upper grip portion 211 and the lower grip portion 212. The upper grip portion 211 and the lower grip portion 212 can provide stable support for the main body 421 and facilitate the installation of the main body 421 without taking up too much space, which helps to improve the compactness of the structure of the connecting device 100.

[0107] like Figure 1 and Figure 7 As shown, in some embodiments, the fixing portion 22 defines a receiving hole 221 , and the limiting member 41 is disposed in the receiving hole 221 .

[0108] The accommodating hole 221 is a through hole.

[0109] The shape and size of the accommodating hole 221 match those of the limiting member 41 , and the limiting member 41 can move along the inner wall of the accommodating hole 221 .

[0110] The elastic member 43 is disposed in the receiving hole 221 , and the receiving hole 221 is a stepped through hole.

[0111] The limiting member 41 includes a limiting body and a boss. The elastic member 43 is sleeved on the limiting body and has one end abutting against the boss and the other end abutting against the bottom wall of the stepped through hole.

[0112] When installing the connecting device 100, first connect the fixing base 10 to the back of the LED display screen 1000, use a pin to rotate the upper gripping portion 211 to connect to the fixing base 10, connect the hook lock member 30 to the rotationally connected fixing portion 22, and fix the fixing portion 22 to the upper gripping portion 211, then place the elastic member 43 in the receiving hole 221 of the fixing portion 22, and insert the limiting member 41 into the receiving hole 221, so that one end of the elastic member 43 abuts against the bottom wall of the receiving hole 221, and the other end abuts against the limiting member 41, then use a pin to rotate the limiting member 41 to connect to the main body 421, and connect the main body 421 to the upper gripping portion 211, and finally connect the lower gripping portion 212 to the upper gripping portion 211, so that the main body 421 is accommodated in the accommodating cavity 213 formed by the upper gripping portion 211 and the lower gripping portion 212.

[0113] When splicing the LED display screen 1000, firstly connect the hook lock member 30 to the connecting structure 200 of the adjacent LED display screen 1000, flip the gripping portion 21 and drive the gripping portion 21 to rotate in the direction close to the LED display screen 1000, and at the same time drive the linkage lock rod assembly 40 to rotate, so that the limit member 41 abuts against the fixing seat 10, and moves along the surface of the fixing seat 10 toward the limit hole 11. At this time, the force of the fixing seat 10 on the limit member 41 is transmitted to the elastic member 43, and the elastic member 43 is compressed and deformed. When the limit member 41 moves to align with the limit hole 11, the force of the fixing seat 10 on the limit member 41 disappears, the elastic member 43 stretches to the original state, and drives the limit member 41 to insert into the limit hole 11, so as to realize the automatic locking of the limit member 41 and fix the rotating assembly 20 to the fixing seat 10.

[0114] When disassembling two adjacent LED display screens 1000, Figure 7 As shown, the pressing portion 422 drives the main body 421 to rotate around its own axis, and drives the limiting member 41 to move out of the limiting hole 11, thereby releasing the locking of the rotating component 20 by the limiting member 41, so that the rotating component 20 can rotate around the fixing seat 10 to an unlocked state. During the rotation, the tension between the rotating component 20 and the hook locking member 30 disappears, and the hook locking member 30 can rotate freely around the fixing portion 22, flipping the hook locking member 30 in a direction away from the connecting structure 200, thereby releasing the connection between the two adjacent LED display screens 1000 and realizing the disassembly of the LED display screen 1000.

[0115] In this embodiment, by opening a receiving hole 221 for accommodating the limiting member 41 on the fixing portion 22, the limiting member 41 can be accurately placed at a specific position of the fixing portion 22, thereby ensuring that the limiting member 41 is firmly fixed on the fixing portion 22, which helps to improve the reliability and stability of the connecting device 100; in addition, the fixing portion 22 can provide installation space for the limiting member 41 and the hook locking member 30 at the same time, which helps to improve the structural compactness of the connecting device 100.

[0116] like Figure 1 As shown, in some embodiments, the connecting device 100 also includes a resilient member 50, the hook locking member 30 includes a hook locking portion 31 and a protrusion 32 provided on the hook locking portion 31, the resilient member 50 is sleeved on the hook locking portion 31, and one end of the resilient member 50 is connected to the fixing portion 22, and the other end of the resilient member 50 abuts against the protrusion 32.

[0117] The resilient member 50 is a structure with elastic deformation capability, for example, a torsion spring, an elastic metal sheet, etc.

[0118] The hook lock portion 31 is the main body of the hook lock member 30. When the LED display screens 1000 are spliced ​​together, the hook lock portion 31 is engaged with the connecting structure 200 on the adjacent LED display screen 1000.

[0119] The raised portion 32 is a structure such as a projection or a bump.

[0120] Optionally, the protrusion 32 may be a screw detachably connected to the hook locking portion 31 .

[0121] One end of the resilient member 50 is connected to the fixed portion 22, and the other end of the resilient member 50 is in contact with the protruding portion 32. When the hook lock portion 31 is rotated to be engaged with the connecting structure 200, the hook lock portion 31 drives the protruding portion 32 to rotate, and the resilient member 50 is twisted and deformed under the action of the protruding portion 32 and the fixed portion 22 to store elastic potential energy. When the LED display screen 1000 is disassembled, the tension between the rotating assembly 20 and the hook lock member 30 disappears, and the resilient member 50 releases the elastic potential energy, driving the hook lock portion 31 to rotate rapidly in a direction away from the connecting structure 200, thereby achieving automatic unlocking.

[0122] In this embodiment, through the cooperation of the fixing portion 22 and the protruding portion 32, when the hook lock portion 31 is rotated to clamp two adjacent LED display screens 1000, the resilient member 50 can be deformed quickly to store elastic potential energy, and at the same time provide elastic support for the hook lock portion 31 to prevent the hook lock portion 31 from shaking or loosening during the rotation process; in addition, when unlocking, the resilient member 50 can release the elastic potential energy to drive the hook lock portion 31 to quickly and automatically complete the unlocking, which helps to improve the convenience and efficiency of operation.

[0123] like Figure 2 and Figure 8 As shown, the present application also provides an LED display screen 1000, including a connection structure 200, and also including the above-mentioned connection device 100, the connection structure 200 and the connection device 100 are respectively arranged at opposite ends of the LED display screen 1000.

[0124] The connection structure 200 is fixedly connected to the LED display screen 1000 .

[0125] The shape and size of the connecting structure 200 are matched with the shape and size of the hook locking member 30 , and the connecting structure 200 can be snap-connected with the hook locking member 30 .

[0126] The number of the connecting structures 200 is the same as the number of the hooking members 30. For example, the number of the hooking members 30 is two, and the number of the connecting structures 200 is also two.

[0127] like Figure 2 and Figure 3As shown, when two adjacent LED display screens 1000 are spliced, the hook lock member 30 of one LED display screen 1000 is snapped into the connection structure 200 of the other LED display screen 1000, and by flipping the rotating assembly 20, the tensioning force between the rotating assembly 20 and the hook lock member 30 tightens the gap between the two adjacent LED display screens 1000. When the rotating assembly 20 is rotated to a locked state, the interlocking locking rod assembly 40 fixes the rotating assembly 20 to the fixed seat 10, so that the rotating assembly 20 cannot rotate, thereby ensuring that the tensioning force between the rotating assembly 20 and the hook lock member 30 always exists, thereby ensuring the reliability of the connection.

[0128] When disassembling two adjacent LED display screens 1000, first switch the interlocking lock rod assembly 40 to the released state to release the lock between the rotating assembly 20 and the fixed base 10, so that the rotating assembly 20 can rotate around the fixed base 10 to the unlocked state, thereby releasing the tension between the rotating assembly 20 and the hook lock member 30, so that the hook lock member 30 can rotate relative to the rotating assembly 20 in a direction away from the connecting structure 200, thereby realizing the disassembly of the two adjacent LED display screens 1000.

[0129] The LED display screen 1000 provided in the embodiment of the present application can realize the quick connection of adjacent LED display screens 1000 through the connecting device 100, and through the double locking of the interlocking lock rod assembly 40 and the hook lock member 30, when unlocking two adjacent LED display screens 1000, the interlocking lock rod assembly 40 and the hook lock member 30 need to be unlocked and released at the same time, which can avoid unlocking due to accidental touching of the interlocking lock rod assembly 40 or the rotating assembly 20 during operation or use, and help to improve the reliability and safety of the LED display screen 1000.

[0130] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
