[0001] This invention relates to the field of LED display technology, and more specifically, to an LED display device insertion / removal mechanism and an LED display device. Background Technology

[0002] In the field of LED (Light-Emitting Diode) display technology, LED display devices comprise multiple display units arranged vertically. Adjacent display units are typically connected using flexible and independent power and data cables during assembly.

[0003] However, power cord connections are complex. To address this issue, a plug-in structure is provided, comprising a socket and a plug inserted into the socket. The socket is mounted on one side of two adjacent display units, and the plug is mounted on the other side of the two adjacent display units. When assembling the two adjacent display units, the plug can be inserted into the socket.

[0004] The sockets and plugs assembled together are prone to loosening due to the weight of the enclosure itself or the vibration of the assembly, which could easily lead to safety accidents. Summary of the Invention

[0005] The main objective of this invention is to provide a plugging and unplugging mechanism for an LED display device and an LED display device in order to solve the problem that sockets and plugs in related technologies are prone to loosening.

[0006] To achieve the above objectives, according to one aspect of the present invention, a plug-in / plug-out mechanism for an LED display device is provided, comprising: a first plug-in / plug-out assembly including a first base, a first plug-in / plug-out member, and a driving member, wherein the first plug-in / plug-out member is movably disposed on the first base, and the driving member is movably disposed on the first base and drives the first plug-in / plug-out member to move; a second plug-in / plug-out assembly including a second base, a second plug-in / plug-out member, and a pushing member, wherein the second plug-in / plug-out member is disposed on the second base, and the pushing member protrudes outward from the second base and is disposed on the second base; the first plug-in / plug-out member has a conductive position where it extends through the first base and contacts and communicates with the second plug-in / plug-out member, and a disconnected position where it retracts into the first base and separates from the second plug-in / plug-out member; the pushing member pushes the driving member to move so that the first plug-in / plug-out member switches from the disconnected position to the conductive position; and locking. The mechanism includes a locking component, a mating part, a traction component, and a reset component. The locking component is movably mounted on a first base body, and the mating part is mounted on a pusher. The locking component is movable in a direction perpendicular to the pusher and has a locked position and an unlocked position. When the locking component is in the locked position, it locks and engages with the mating part, keeping the first plug-in member in a conductive position. When the locking component is in the unlocked position, it disengages from the mating part, allowing the first plug-in member to switch between a conductive position and a disconnected position. One end of the traction component is connected to the locking component, and the other end of the traction component is located outside the first base body. The reset component is connected to the locking component and the first base body. The reset component applies a reset force to the locking component to maintain it in the unlocked position, and the traction component applies a traction force to the locking component to switch it from the unlocked position to the locked position.

[0007] Furthermore, the locking assembly includes a locking pin and a connecting rod structure hinged to the locking pin. The mating part is a mating hole. One end of the traction assembly is connected to the connecting rod structure. The reset member is connected between the connecting rod structure and the first seat. The traction assembly applies a traction force to the connecting rod structure, and the reset member applies a reset force to the connecting rod structure. The locking pin has a locked position and an unlocked position. When the locking pin is inserted into the mating hole, the locking pin is in the locked position. When the locking pin is disengaged from the mating hole, the locking pin is in the unlocked position.

[0008] Furthermore, when the locking pin is in the locked position, the locking pin is in clearance fit with the mating hole. The locking pin also has the ability to move from the locked position toward the free end of the pusher to the abutting position where it abuts against the pusher. The locking assembly also includes a lifting member rotatably disposed on the first base. The lifting member is hinged to and driven by the connecting rod structure. The lifting member can push the locking pin from the locked position to the abutting position.

[0009] Furthermore, the lifting component includes a lifting ring and a first inclined surface disposed on the lifting ring. A second inclined surface is disposed on the first base body and engages with the first inclined surface. Both the first and second inclined surfaces extend along the spiral reference line formed circumferentially by the lifting ring. The surface of the lifting ring away from the first inclined surface pushes the locking pin to move.

[0010] Furthermore, the locking pin includes a pin segment, a first rod segment, and a second rod segment connected in sequence. The first rod segment is vertically connected to the pin segment in a horizontal plane, and the second rod segment is vertically connected to the first rod segment in a vertical plane. A support plane for supporting the pin segment is provided in the first housing. The support plane supports the pin segment so that the locking pin is kept on a horizontal plane. During the process of switching between the unlocked position and the locked position, the pin segment moves horizontally on the support plane to insert into or disengage from the mating hole.

[0011] Furthermore, the linkage structure includes a first linkage and a second linkage hinged to the first linkage. A first hinge pin is provided on the locking pin, and a second hinge pin is provided on the lifting member. A first limiting elongated hole is provided at the first end of the first linkage, and the first hinge pin is located in the first limiting elongated hole. A second limiting elongated hole is provided at the first end of the second linkage, and the second hinge pin is located in the second limiting elongated hole. The second end of the first linkage is connected to the second end of the second linkage through a third hinge pin. The plane where the second limiting elongated hole is located is perpendicular to the plane where the first limiting elongated hole is located. One end of the traction assembly is hinged to the first linkage, and the reset member is connected between the first linkage and the first seat.

[0012] Furthermore, the traction assembly includes a traction seat, a traction plate, and a traction line. The traction seat is disposed outside the first plug-in assembly. The traction plate is rotatably disposed on the traction seat. The first end of the traction line is connected to the locking assembly. The second end of the traction line is connected to the traction plate through a connecting shaft. The connecting shaft and the rotation axis of the traction plate are spaced apart so that the second end of the traction line rotates around the rotation axis of the traction plate. The traction line applies a traction force to the locking assembly.

[0013] Furthermore, the traction assembly also includes a stop structure spaced apart from the traction seat. The stop structure includes a stop seat and a stop pin movably disposed on the stop seat. The two ends of the traction plate are respectively provided with a first bayonet and a second bayonet that cooperate with the stop pin. The connecting shaft is located between the rotation axis of the traction plate and the second bayonet. When the stop pin is inserted into the first bayonet, the locking assembly is kept in the unlocked position under the action of the reset force. When the stop pin is inserted into the second bayonet, the locking assembly is kept in the locked position under the action of the traction force.

[0014] Furthermore, the traction assembly includes a traction seat, a traction plate, and a traction line. The traction seat is disposed outside the first plug-in assembly. The traction plate is rotatably disposed on the traction seat. The first end of the traction line is connected to a connecting rod structure, and the second end of the traction line is connected to the traction plate via a connecting shaft. The connecting shaft is spaced apart from the rotation axis of the traction plate so that the second end of the traction line rotates around the rotation axis of the traction plate. The traction line applies a traction force to the locking assembly. The traction assembly also includes a stop structure spaced apart from the traction seat. The stop structure includes a stop seat and a stop pin movably disposed on the stop seat. The two ends of the traction plate are respectively provided with a first latch and a second latch that cooperate with the stop pin. The connecting shaft is located between the rotation axis of the traction plate and the second latch. When the stop pin is inserted into the first latch, the locking assembly is held in the unlocked position under the action of a reset force. When the stop pin is inserted into the second latch, the locking assembly is held in the abutting position under the action of a traction force.

[0015] Furthermore, the first plug-in component includes a first power plug-in portion and a first signal plug-in portion spaced apart on the first base body, and a driving member drives the first power plug-in portion and the first signal plug-in portion to move. The second plug-in component includes a second power plug-in portion and a second signal plug-in portion spaced apart on the second base body. When the first power plug-in portion is in contact with the second power plug-in portion and the first signal plug-in portion is in contact with the first signal plug-in portion, the first plug-in component is in the conducting position. When the first power plug-in portion is separated from the second power plug-in portion and the first signal plug-in portion is separated from the first signal plug-in portion, the first plug-in component is in the disconnected position.

[0016] According to another aspect of the present invention, an LED display device is provided, including a first display unit, a second display unit, and a plug-in mechanism. The first display unit and the second display unit are arranged side by side and / or vertically. The plug-in mechanism is the plug-in mechanism of the LED display device described above. A first plug-in component of the plug-in mechanism is installed on a first side adjacent to the first display unit and the second display unit. A second plug-in component of the plug-in mechanism is installed on a second side adjacent to the second display unit and the first display unit. A locking mechanism of the plug-in mechanism is installed on a third side of the first display unit opposite to the first side.

[0017] According to the technical solution of this invention, the plug-in / plug-out mechanism of an LED display device includes: a first plug-in / plug-out assembly, a second plug-in / plug-out assembly, and a locking mechanism. The first plug-in / plug-out assembly of the LED display device can be installed on one adjacent side of two adjacent display units, and the second plug-in / plug-out assembly of the LED display device can be installed on the other adjacent side of two adjacent display units. The first plug-in / plug-out assembly includes a first base, a first plug-in / plug-out member, and a driving member. The first plug-in / plug-out member is movably disposed on the first base, and the driving member is movably disposed on the first base and drives the first plug-in / plug-out member to move. The second plug-in / plug-out assembly includes a second base, a second plug-in / plug-out member, and a pushing member. The second plug-in / plug-out member is disposed on the second base, and the pushing member protrudes outward from the second base and is disposed on the second base. During the assembly of two adjacent display units, the first plug-in / plug-out member has a conductive position where it extends through the first base and contacts and connects with the second plug-in / plug-out member, and a disconnected position where it retracts into the first base and separates from the second plug-in / plug-out member. The pushing member pushes the driving member to move, causing the first plug-in / plug-out member to switch from the disconnected position to the conductive position. The locking mechanism includes a locking component, a mating part, a traction component, and a reset component. The locking component is movably mounted on the first base, and the mating part is mounted on the pusher. The locking component is movable in a direction perpendicular to the pusher and has a locked position and an unlocked position. When the locking component is in the locked position, it locks into the mating part, keeping the first plug / plug in the on position. When the locking component is in the unlocked position, it disengages from the mating part, allowing the first plug / plug to switch between the on and off positions. One end of the traction component is connected to the locking component, and the other end is located outside the first base. The reset component is connected to both the locking component and the first base. The reset component applies a reset force to the locking component to maintain it in the unlocked position, and the traction component applies a traction force to the locking component to switch it from the unlocked position to the locked position. Thus, under the action of the traction force, the locking component is kept in the locked position, preventing it from switching from the locked to the unlocked position, avoiding the first plug / plug from becoming detached from the second plug / plug, and reducing the possibility of safety accidents. Therefore, the technical solution of this application effectively solves the problem of easy detachment of sockets and plugs in related technologies. Furthermore, by having the locking component in the locked position, the locking mechanism achieves the purpose of locking two adjacent display units. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 10As shown, the plug-in / plug-out mechanism of the LED display device in this embodiment includes: a first plug-in / plug-out assembly 10, a second plug-in / plug-out assembly 20, and a locking mechanism 30. The first plug-in / plug-out assembly 10 includes a first base 11, a first plug-in / plug-out member 12, and a driving member 13. The first plug-in / plug-out member 12 is movably disposed on the first base 11, and the driving member 13 is movably disposed on the first base 11 and drives the first plug-in / plug-out member 12 to move. The second plug-in / plug-out assembly 20 includes a second base 21, a second plug-in / plug-out member 22, and a pushing member 23. The second plug-in / plug-out member 22 is disposed on the second base 21, and the pushing member 23 protrudes outward from the second base 21. The first plug-in / plug-out member 12 has a conductive position where it passes through the first base 11 and contacts and connects with the second plug-in / plug-out member 22, and a disconnected position where it retracts into the first base 11 and separates from the second plug-in / plug-out member 22. The pushing member 23 pushes the driving member 13 to move so that the first plug-in / plug-out member 12 switches from the disconnected position to the conductive position. The locking mechanism 30 includes a locking component 50, a mating part, a traction component 31, and a reset component 33. The locking component 50 is movably disposed on the first base 11, and the mating part is disposed on the pusher 23. The locking component 50 is movable in a direction perpendicular to the pusher 23 and has a locked position and an unlocked position. When the locking component 50 is in the locked position, it locks and engages with the mating part, keeping the first plug-in member 12 in the conducting position. When the locking component 50 is in the unlocked position, it disengages from the mating part, allowing the first plug-in member 12 to switch between the conducting position and the disconnected position. One end of the traction component 31 is connected to the locking component 50, and the other end of the traction component 31 is located outside the first base 11. The reset component 33 is connected to the locking component 50 and the first base 11. The reset component 33 applies a reset force to the locking component 50 to maintain it in the unlocked position, and the traction component 31 applies a traction force to the locking component 50 to switch it from the unlocked position to the locked position.

[0037] Using the technical solution of this embodiment, the plug-in / plug-out mechanism of the LED display device includes: a first plug-in / plug-out component 10, a second plug-in / plug-out component 20, and a locking mechanism 30. The first plug-in / plug-out component 10 of the LED display device plug-in / plug-out mechanism can be installed on one adjacent side of two adjacent display units, and the second plug-in / plug-out component 20 of the LED display device plug-in / plug-out mechanism can be installed on the other adjacent side of two adjacent display units. During the assembly of two adjacent display units, the first plug-in / plug-out component 12 has a conductive position where it protrudes from the first base 11 and contacts and connects with the second plug-in / plug-out component 22, and a disconnected position where it retracts into the first base 11 and separates from the second plug-in / plug-out component 22. The pusher 23 pushes the drive 13 to move, causing the first plug-in / plug-out component 12 to switch from the disconnected position to the conductive position. The locking component 50 is movable in a direction perpendicular to the pusher 23 and has a locked position and an unlocked position. When the locking component 50 is in the locked position, it locks into the mating part and keeps the first plug-in / plug-out component 12 in the conductive position. When the locking component 50 is in the unlocked position, it separates from the mating part, allowing the first plug-in member 12 to switch between the on and off positions. One end of the traction component 31 is connected to the locking component 50, and the other end of the traction component 31 is located outside the first base 11. The reset component 33 is connected to the locking component 50 and the first base 11. The reset component 33 applies a reset force to the locking component 50 to maintain it in the unlocked position, and the traction component 31 applies a traction force to the locking component 50 to switch it from the unlocked position to the locked position. In this way, under the action of the traction force, the locking component 50 can be kept in the locked position, preventing the locking component 50 from switching from the locked position to the unlocked position, avoiding the first plug-in member 12 from becoming detached from the second plug-in member 22, and reducing the possibility of safety accidents. Therefore, the technical solution of this embodiment effectively solves the problem of sockets and plugs easily becoming detached in related technologies. Furthermore, by having the locking component 50 in the locked position, the locking mechanism 30 serves to lock two adjacent display units.

[0038] The other end of the aforementioned traction component 31 being located outside the first seat 11 means that the other end of the traction component 31 needs to be pulled, and this other end of the traction component 31 is exposed outside the first seat 11. In this embodiment, the reset member 33 is preferably a tension spring.

[0039] like Figures 1 to 4As shown, the locking assembly 50 includes a locking pin 51 and a connecting rod structure 52 hinged to the locking pin 51. The mating part is a mating hole 40. One end of the traction assembly 31 is connected to the connecting rod structure 52, and a reset member 33 is connected between the connecting rod structure 52 and the first seat 11. The traction assembly 31 applies a traction force to the connecting rod structure 52, and the reset member 33 applies a reset force to the connecting rod structure 52. The locking pin 51 has a locked position and an unlocked position. When the locking pin 51 is inserted into the mating hole 40, it is in the locked position; when the locking pin 51 is disengaged from the mating hole 40, it is in the unlocked position. Thus, the connecting rod structure 52 can easily drive the locking pin 51 to move. Furthermore, the mating structure between the locking pin 51 and the mating hole 40 is simple and easy to manufacture.

[0040] like Figures 1 to 4 As shown, when the locking pin 51 is in the locked position, it is in clearance fit with the mating hole 40. The locking pin 51 also has a position where it can move from the locked position toward the free end of the pusher 23 to abutting with the pusher 23. The locking assembly 50 also includes a lifting member 53 rotatably disposed on the first base 11. The lifting member 53 is hinged to and driven by the connecting rod structure 52. The lifting member 53 can push the locking pin 51 from the locked position to the abutting position. In this way, when the lifting member 53 is in the abutting position, it always pushes the locking pin 51, so that the locking pin 51 is always in abutting fit with the pusher 23. The pusher 23 cannot wobble in the first base 11, which can prevent the first plug-in member 12 and the second plug-in member 22 from becoming loose, and ensure that the first plug-in assembly 10 and the second plug-in assembly 20 can be reliably plugged together.

[0041] In this embodiment, the reset force of the reset member 33 is the first force, and the traction force of the traction assembly 31 is the second force. When the traction force can overcome the first force, the locking pin 51 switches from the unlocked position to the locked position under the initial action of the traction force, and then switches from the locked position to the abutting position under the second action of the traction force. When the reset force can overcome the second force, the locking pin 51 switches from the abutting position to the locked position under the initial action of the reset force, and then switches from the locked position to the unlocked position under the second action of the reset force.

[0042] like Figures 3 to 5As shown, the lifting member 53 includes a lifting ring 531 and a first inclined surface 532 disposed on the lifting ring 531. The lifting ring 531 is positioned to facilitate the insertion of the pusher 23 within the lifting member 53 and its rotation around the pusher 23. The mating hole 40 on the pusher 23 can be located above the lifting member 53. The first base 11 is provided with a second inclined surface 113 that contacts and engages with the first inclined surface 532. Both the first inclined surface 532 and the second inclined surface 113 extend along the spiral reference line formed circumferentially by the lifting ring 531. The spiral reference line formed circumferentially by the lifting ring 531 can convert the rotation of the lifting ring 531 into movement, so that the lifting ring 531 can push the locking pin 51 to move away from the surface of the first inclined surface 532. Consequently, the locking pin 51 can engage with the pusher 23.

[0043] In this embodiment, the first seat 11 includes a seat body and a cover plate 112 covering the opening of the seat body. The lifting member 53 is rotatably disposed in the seat body. The second inclined surface 113 is disposed on the surface of the cover plate 112 facing the lifting ring 531. The cover plate 112 is provided with a first clearance hole for the push member 23 to pass through.

[0044] like Figures 2 to 5 As shown, the locking pin 51 includes a pin segment 511, a first rod segment 512, and a second rod segment 513 connected in sequence. The first rod segment 512 is vertically connected to the pin segment 511 in a horizontal plane, and the second rod segment 513 is vertically connected to the first rod segment 512 in a vertical plane. Thus, the connecting rod structure 52 is hinged to the second rod segment 513. When the connecting rod structure 52 moves the second rod segment 513, the direction of movement of the pin segment 511 is consistent with the overall direction of movement of the connecting rod structure 52. A support plane 111 is provided inside the first base 11 to support the pin segment 511. The support plane 111 supports the pin segment 511, keeping the locking pin 51 on a horizontal plane. During the switching between the unlocked and locked positions, the pin segment 511 moves horizontally on the support plane 111 to insert into or disengage from the mating hole 40.

[0045] Specifically, the first base 11 has a limiting cavity that accommodates the pin segment 511 and part of the first rod segment 512. The first rod segment 512 extends from the opening of the limiting cavity in the vertical plane to the outside of the first base 11, and the second rod segment 513 is located on the outside of the first base 11. The supporting plane 111 is the lower side of the limiting cavity. When the first rod segment 512 is in a limiting engagement with the end wall of the limiting cavity near the reset member 33, the locking pin 51 is in the unlocked position; when the first rod segment 512 is in a limiting engagement with the end wall of the limiting cavity away from the reset member 33, the locking pin 51 is in the locked position.

[0046] like Figures 2 to 5As shown, the linkage structure 52 includes a first linkage 521 and a second linkage 522 hinged to the first linkage 521. A first hinge pin 514 is provided on the locking pin 51, and a second hinge pin 515 is provided on the lifting member 53. A first limiting elongated hole 517 is provided at the first end of the first linkage 521, and the first hinge pin 514 is disposed within the first limiting elongated hole 517. During the process of the locking pin 51 switching from the unlocked position to the locked position, the first hinge pin 514 slides relative to the first linkage 521 within the first limiting elongated hole 517. A second limiting elongated hole 518 is provided at the first end of the second linkage 522, and the second hinge pin 515 is disposed within the second limiting elongated hole 518. During the process of the locking pin 51 switching from the locked position to the abutting position, the second hinge pin 515 slides relative to the second linkage 522 within the second limiting elongated hole 518. The second end of the first connecting rod 521 is connected to the second end of the second connecting rod 522 via a third hinge pin 516. The third hinge pin 516 facilitates rotation of the second end of the first connecting rod 521 relative to the second end of the second connecting rod 522, allowing the second end of the second connecting rod 522 to move. The plane containing the second limiting elongated hole 518 is perpendicular to the plane containing the first limiting elongated hole 517. One end of the traction assembly 31 is hinged to the first connecting rod 521. The reset member 33 is connected between the first connecting rod 521 and the first seat 11. The length of the major axis of the first limiting elongated hole 517 is greater than the length of its minor axis, and the length of the major axis of the second limiting elongated hole 518 is greater than the length of its minor axis.

[0047] Specifically, when the first segment 512 of the locking pin 51 is engaged with the end wall of the limiting cavity near the reset member 33, the position of the first hinge pin 514 on the locking pin 51 remains stationary, and the side end wall of the first limiting elongated hole 517 near the reset member 33 is engaged with the first hinge pin 514. The reset member 33 cannot pull the first connecting rod 521, so that the locking pin 51 remains in the unlocked position.

[0048] During the transition from the unlocked to the locked position, the traction assembly 31 pulls the first connecting rod 521, causing its second end to rotate around the third hinge axis 516. This rotation, along with the first limiting elongated hole 517 on the first connecting rod 521, pushes the first hinge axis 514, causing it to slide within the first limiting elongated hole 517. Simultaneously, this moves the locking pin 51 from the unlocked to the locked position on the support plane 111. During this process, the side wall of the second limiting elongated hole 518 near the pusher 23 engages with the second hinge axis 515, keeping the second connecting rod 522 stationary. When the first segment 512 of the locking pin 51 engages with the end wall of the limiting cavity away from the reset member 33, the first hinge axis 514 on the locking pin 51 stops sliding, and the side wall of the first limiting elongated hole 517 away from the reset member 33 engages with the first hinge axis 514. At this point, the locking pin 51 is in the locked position.

[0049] During the process of switching from the locked position to the abutting position, the traction assembly 31 continues to pull the first connecting rod 521. At this time, the second end of the first connecting rod 521 changes from rotating around the third hinge axis 516 to rotating around the first hinge axis 514. It pushes the second end of the second connecting rod 522 to move away from the reset member 33 through the third hinge axis 516. At this time, the second limiting elongated hole 518 on the second connecting rod 522 pushes the second hinge axis 515, causing the second hinge axis 515 to slide in the second limiting elongated hole 518. At the same time, it drives the lifting member 53 to rotate around the push member 23. Since the first inclined surface 532 on the lifting member 53 contacts and engages with the second inclined surface 113, the rotation of the lifting member 53 can be converted into the movement of the lifting locking pin 51. When the locking pin 51 moves to contact the top wall of the mating hole 40, the locking pin 51 can engage with the push member 23, and the second hinge axis 515 stops sliding. At this time, the locking pin 51 is in the abutting position.

[0050] When the second hinge pin 515 stops sliding, the side wall of the second limiting elongated hole 518 away from the pusher 23 is engaged with the second hinge pin 515, the position of the second connecting rod 522 remains stationary, and the traction assembly 31 cannot pull the first connecting rod 521 so that the locking pin 51 is kept in the abutting position.

[0051] like Figure 3 , Figure 6 and Figure 7 As shown, the traction assembly 31 includes a traction seat 311, a traction plate 312, and a traction line 313. The traction seat 311 is disposed outside the first insertion / removal assembly 10. The traction plate 312 is rotatably disposed on the traction seat 311. The first end of the traction line 313 is connected to the linkage structure 52, and the second end of the traction line 313 is connected to the traction plate 312 via a connecting shaft 314. The connecting shaft 314 and the rotation axis of the traction plate 312 are spaced apart so that the second end of the traction line 313 rotates around the rotation axis of the traction plate 312. The traction line 313 applies a traction force to the locking assembly 50. In this way, the traction plate 312 rotates on the traction seat 311 to pull the traction line 313, causing the traction plate 312 to drive the second end of the traction line 313 to rotate around the rotation axis of the traction plate 312 via the connecting shaft 314. Thus, the traction line 313 can apply a traction force to the linkage structure 52, facilitating the movement of the locking assembly 50 from the unlocked position to the locked position and then from the locked position to the abutment position. Conversely, when the reset member 33 pulls the connecting rod structure 52, a reset force is applied to the connecting rod structure 52, which facilitates the connecting rod structure 52 to drive the locking component 50 from the abutting position to the locked position and then from the locked position to the unlocked position.

[0052] Specifically, the first end of the traction line 313 is hinged to the first link 521 via a connecting hinge.

[0053] like Figure 3 , Figure 6 and Figure 7 As shown, the traction assembly 31 also includes a stop structure 32 spaced apart from the traction seat 311. The stop structure 32 includes a stop seat 321 and a stop pin 322 movably disposed on the stop seat 321. The two ends of the traction plate 312 are respectively provided with a first latch 315 and a second latch 316 that cooperate with the stop pin 322. The connecting shaft 314 is located between the rotation axis of the traction plate 312 and the second latch 316. When the traction plate 312 is driven by the reset force to rotate counterclockwise around its rotation axis, and when it rotates to the position corresponding to the stop pin 322 and the first latch 315, when the stop pin 322 is inserted into the first latch 315, the locking assembly 50 is kept in the unlocked position under the action of the reset force. The traction plate 312 is manually or with the aid of tools driven to rotate clockwise around its rotation axis. When it rotates to the position corresponding to the stop pin 322 and the second latch 316, the locking component 50 is held in the abutting position under the action of the traction force when the stop pin 322 is inserted into the second latch 316. In this embodiment, the traction plate 312 can rotate 180 degrees. When the first latch 315 and the second latch 316 on the traction plate 312 are respectively engaged with the stop pin 322, it is convenient for the locking component 50 to switch between the unlocked position and the abutting position, which is convenient to operate and easy to implement. Moreover, when the locking component 50 is held in the abutting position, it can enhance the stability of locking when the LED display device's plug-in mechanism is engaged. At the same time, when the locking component 50 is held in the unlocked position, the LED display device's plug-in mechanism will not loosen on the display unit, which can enhance the stability of installation.

[0054] In this embodiment, the stop seat 321 is provided with a guide hole for the stop pin 322 to pass through. An elastic element 323 is provided inside the stop seat 321. The elastic element 323 is sleeved on the outside of the stop pin 322 and located between the stop pin 322 and the inner wall of the stop seat 321. The elastic element 323 applies a spring force to the stop pin 322 in the direction of the traction plate 312. Thus, during the rotation of the traction plate 312 by 180 degrees, if the stop pin 322 is manually driven or squeezed by the traction plate 312, the stop pin 322 will retract a certain distance within the stop seat 321. When the traction plate 312 rotates to the position corresponding to the stop pin 322 in the first latch 315 or the second latch 316, under the action of the spring force of the elastic element 323, the stop pin 322 moves towards the traction plate 312 and can be inserted into the first latch 315 or the second latch 316.

[0055] Of course, in embodiments not shown in the figures, the traction assembly includes a traction seat, a traction plate, and a traction line. The traction seat is disposed outside the first plug-in assembly. The traction plate is rotatably disposed on the traction seat. The first end of the traction line is connected to the locking assembly, and the second end of the traction line is connected to the traction plate via a connecting shaft. The connecting shaft is spaced apart from the rotation axis of the traction plate so that the second end of the traction line rotates around the rotation axis of the traction plate. The traction line applies a traction force to the locking assembly. The traction assembly also includes a stop structure spaced apart from the traction seat. The stop structure includes a stop seat and a stop pin movably disposed on the stop seat. The two ends of the traction plate are respectively provided with a first latch and a second latch that cooperate with the stop pin. The connecting shaft is located between the rotation axis of the traction plate and the second latch. When the stop pin is inserted into the first latch, the locking assembly is held in the unlocked position under the action of a reset force. When the stop pin is inserted into the second latch, the locking assembly is held in the locked position under the action of a traction force. In this way, the traction plate rotates on the traction seat to pull the traction line, causing the second end of the traction line to rotate around the rotation axis of the traction plate via the connecting shaft. This allows the traction line to apply traction force to the linkage structure, facilitating the movement of the locking assembly from the unlocked position to the locked position. Conversely, the reset member pulls the linkage structure to apply a reset force, facilitating the linkage structure to move the locking assembly from the locked position to the unlocked position.

[0056] like Figure 1 As shown, the first plug-in member 12 includes a first power plug-in portion 121 and a first signal plug-in portion 122 spaced apart on the first base 11. The driving member 13 drives the first power plug-in portion 121 and the first signal plug-in portion 122 to move. The second plug-in member 22 includes a second power plug-in portion 221 and a second signal plug-in portion 222 spaced apart on the second base 21. When the first power plug-in portion 121 is in contact with the second power plug-in portion 221 and the first signal plug-in portion 122 is in contact with the first signal plug-in portion 122, the first plug-in member 12 is in the conducting position. When the first power plug-in portion 121 is separated from the second power plug-in portion 221 and the first signal plug-in portion 122 is separated from the first signal plug-in portion 122, the first plug-in member 12 is in the disconnected position.

[0057] like Figure 1As shown, the first plug-in component 12 also includes a function switch (not shown in the figure). The driving component 13 includes a first driving component 131 and a second driving component 132. The first driving component 131 is movably disposed on the first base 11 and drives the first power plug-in part 121 to move, and the second driving component 132 is movably disposed on the first base 11 and drives the first signal plug-in part 122 to move. The function switch is movably disposed on the first base 11 and has multiple working positions. When the function switch is in different working positions, it can drive the first driving component 131 and / or the second driving component 132 to move. When the function switch is in the working position that puts the first plug-in part 12 in the conducting position, the push top is inserted into the first base 11 and the first drive part 131 and the second drive part 132 are moved by the function switch, so that the separation of the first power plug-in part 121 and the second power plug-in part 221 is switched to the contact conduction of the first power plug-in part 121 and the second power plug-in part 221, and the separation of the first signal plug-in part 122 and the first signal plug-in part 122 is switched to the contact conduction of the first signal plug-in part 122 and the first signal plug-in part 122.

[0058] This application also provides an LED display device, such as... Figures 8 to 10 As shown, the LED display device of this embodiment includes a first display unit 61, a second display unit 62, and a plug-in mechanism. The first display unit 61 is one of the two adjacent display units mentioned above, and the second display unit 62 is the other of the two adjacent display units mentioned above. The first display unit 61 and the second display unit 62 are arranged vertically. The plug-in mechanism is the plug-in mechanism of the LED display device described above. The first plug-in component 10 of the plug-in mechanism is installed on a first side adjacent to the first display unit 61 and the second display unit 62, the second plug-in component 20 of the plug-in mechanism is installed on a second side adjacent to the second display unit 62 and the first display unit 61, and the locking mechanism 30 of the plug-in mechanism is installed on a third side 611 of the first display unit 61 opposite to the first side. Because the plug-in mechanism of the LED display device described above can solve the problem of sockets and plugs easily becoming loose in related technologies, the LED display device with this plug-in mechanism can solve the same technical problem. Of course, the first plug-in assembly 10, the second plug-in assembly 20 and the locking mechanism 30 of the plug-in mechanism can also be installed on a first display unit 61, that is, the first plug-in assembly 10 of the plug-in mechanism is installed on the first side of the first display unit 61, and the second plug-in assembly 20 and the locking mechanism 30 are both installed on the third side 611 of the first display unit 61 opposite to the first side.

[0059] Specifically, the third side 611 is provided with a second clearance hole and a third clearance hole spaced apart. The traction plate 312 is located in the second clearance hole, and part of the stop pin 322 is located in the third clearance hole. The traction plate 312 and the stop pin 322 can be touched from the outside of the first display unit 61 through the second clearance hole and the third clearance hole. One end of the traction plate 312 can be driven to rotate clockwise around its rotation axis by manually or with the aid of a tool through the second clearance hole. The other end of the traction plate 312 is rotated to the outside of the first display unit 61 through the second clearance hole, which facilitates manual driving of the other end of the traction plate 312 to rotate the traction plate 312 to a position where the first latch 315 or the second latch 316 on the traction plate 312 corresponds to the stop pin 322.
