Description

Technical Field

[0001] This utility model relates to the field of LED display device technology, and more specifically, to an LED display device. Background Technology

[0002] LED displays typically consist of a cabinet and display modules. The display modules are detachably connected to the cabinet, facilitating maintenance. Specifically, the cabinet is equipped with movable retaining pins. When the display modules are installed into the cabinet, the retaining pins are inserted into the receiving portions on the display modules, thereby securing the display modules to the cabinet.

[0003] In existing technology, to facilitate the disassembly of the display module, a through hole is provided on the front side of the display module. When it is necessary to disassemble the display module, the release part passes through the through hole and abuts against the limiting pin. The release part then drives the limiting pin to move, causing the limiting pin to separate from the display module, thereby allowing the display module to be separated from the housing and achieving disassembly. However, this design means that the display module can only be disassembled from the front of the LED display screen, making disassembly inconvenient. Utility Model Content

[0004] The main objective of this invention is to provide an LED display device to solve the problem that LED display modules in related technologies can only be disassembled from the front.

[0005] To achieve the above objectives, this utility model provides an LED display device, comprising: a housing; an LED display module detachably mounted on the housing, the LED display module having a first disassembly hole extending through the LED display module along its thickness direction; a locking structure including a first locking groove and a movably mounted first locking part, one of the first locking part and the first locking groove being mounted on the housing, and the other being mounted on the LED display module, the first locking groove communicating with the first disassembly hole; an operating member having an operating state inserted into the first disassembly hole and a disengaged state separated from the first disassembly hole; and an anti-detachment structure mounted on the LED display module, wherein when the operating member is in the operating state, the operating member and the anti-detachment structure are anti-detached; wherein, when the LED display module is mounted on the housing, the first locking part is in a first extended position inserted into the first locking groove; when the operating member is in the operating state, the operating member triggers the first locking part, which can switch to a first retracted position separated from the first locking groove, so that the LED display module can be separated from the housing.

[0006] Furthermore, the anti-detachment structure is movably configured, and the operating component has a mating part. When the operating component is in the operating state, the anti-detachment structure and the mating part engage to prevent the LED display module from detaching from the operating component.

[0007] Furthermore, the mating part includes a groove, and the anti-detachment structure includes a first elastic reset member and a second locking part. The first elastic reset member applies an elastic force to the second locking part to keep the second locking part in the groove.

[0008] Furthermore, the locking structure also includes a second locking groove and a movably disposed third locking part. One of the third locking part and the second locking groove is disposed on the housing, and the other of the third locking part and the second locking groove is disposed on the LED display module. The LED display module is also provided with a second disassembly hole, which penetrates the LED display module along the thickness direction and is connected to the second locking groove. When the LED display module is installed on the housing, the third locking part is in a second extended position inserted into the second locking groove. When the operating member is in the operating state, the operating member simultaneously triggers the first locking part and the third locking part. The third locking part can switch to a second retracted position separated from the second locking groove, so that the LED display module can be separated from the housing.

[0009] Furthermore, the locking structure also includes a second elastic reset member, which is disposed between the first locking part and the third locking part.

[0010] Furthermore, the operating component includes a first operating piece and a second operating piece connected to the first operating piece. When the operating component is in the operating state, the first operating piece is inserted into the first disassembly hole and triggers the first locking part, and the second operating piece is inserted into the second disassembly hole and triggers the third locking part.

[0011] Furthermore, a guide portion is provided at one end of the first operating piece inserted into the first disassembly hole. When the operating piece switches from the separated state to the operating state, the guide portion abuts and engages with the first locking portion.

[0012] Furthermore, the operating component also includes a gripping part, which is connected between the first operating plate and the second operating plate.

[0013] Furthermore, the first locking part is disposed on the housing, the LED display module includes a lamp board and a first connecting seat disposed on the rear side of the lamp board, the first disassembly hole passes through the lamp board and the first connecting seat, the first locking groove is disposed on the first connecting seat, the first connecting seat is also provided with a connecting hole, and the second locking part passes through the connecting hole and extends into the first disassembly hole.

[0014] Furthermore, the LED display module also includes a second connector disposed on the rear side of the lamp panel. The second connector is spaced apart from the first connector. The first end of the first elastic reset member abuts against the second connector, and the second end of the first elastic reset member abuts against the second locking part.

[0015] According to the technical solution of this utility model, the LED display device includes a housing, an LED display module, and a locking structure. The LED display module is detachably mounted on the housing, and a first disassembly hole is provided on the LED display module, penetrating the LED display module along its thickness direction. The locking structure includes a first locking groove and a first locking part. The first locking part is movably mounted on the housing, and the first locking groove is located on the LED display module, communicating with the first disassembly hole. The operating member has an operating state and a disengaged state. When the operating member is in the operating state, it is inserted into the first disassembly hole; when the operating member is in the disengaged state, it is separated from the first disassembly hole. When the LED display module is mounted on the housing, the first locking part is in a first extended position, at which time it is inserted into the first locking groove. When the operating member is in the operating state, the first locking part is triggered by the operating member, and it can switch to a first retracted position. At this time, the first locking part separates from the first locking groove, and the LED display module can be separated from the housing. With the above-described configuration, the first disassembly hole penetrates the thickness direction of the LED display module. This facilitates the operator inserting the operating component from the front or rear of the LED display module. The operating component then triggers the first locking part, causing it to switch from a first extended position to a first retracted position. In other words, the first locking part can separate from the first locking groove, allowing the LED display module to separate from the housing. Therefore, when the first disassembly hole is provided, it is convenient to operate from the front or rear of the LED display module to disassemble it. The anti-detachment structure cooperates with the anti-detachment mechanism of the operating component, ensuring that when the operating component is in operation, pushing it pushes the LED display module out, and the LED display module is not easily separated from the operating component, thus preventing the LED display module from falling off the operating component. Therefore, the technical solution of this application effectively solves the problem in related technologies where LED display modules can only be disassembled from the front.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, 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 utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0032] like Figures 1 to 3 , Figure 6 , Figures 7 to 12As shown, the LED display device of this embodiment includes: a housing 10, an LED display module 20, and a locking structure 30. The LED display module 20 is detachably mounted on the housing 10, and a first disassembly hole 21 is provided on the LED display module 20, extending through the LED display module 20 along its thickness direction. The locking structure 30 includes a first locking groove 31 and a movably mounted first locking part 32. One of the first locking part 32 and the first locking groove 31 is mounted on the housing 10, and the other of the first locking part 32 and the first locking groove 31 is mounted on the LED display module 20. The first locking groove 31 communicates with the first disassembly hole 21. The operating member 40 has an operating state of being inserted into the first disassembly hole 21 and a disengaged state of being separated from the first disassembly hole 21. An anti-detachment structure 50 is provided on the LED display module 20, and when the operating member 40 is in the operating state, the operating member 40 is anti-detached from the anti-detachment structure 50. When the LED display module 20 is installed on the housing 10, the first locking part 32 is in the first extended position inserted into the first locking groove 31. When the operating member 40 is in the operating state, the operating member 40 triggers the first locking part 32, and the first locking part 32 can switch to the first retracted position separated from the first locking groove 31, so that the LED display module 20 can be separated from the housing 10.

[0033] Using the technical solution of this embodiment, the LED display device includes a housing 10, an LED display module 20, and a locking structure 30. The LED display module 20 is detachably mounted on the housing 10, and a first disassembly hole 21 is provided on the LED display module 20, penetrating the LED display module 20 along its thickness direction. The locking structure 30 includes a first locking groove 31 and a first locking part 32. The first locking part 32 is movably mounted on the housing 10, and the first locking groove 31 is mounted on the LED display module 20, communicating with the first disassembly hole 21. The operating member 40 has an operating state and a disengaged state. When the operating member 40 is in the operating state, it is inserted into the first disassembly hole 21; when the operating member 40 is in the disengaged state, it is separated from the first disassembly hole 21. The LED display module 20 is provided with an anti-detachment structure 50, which prevents the operating member 40 from detaching when it is in the operating state. When the LED display module 20 is installed on the housing 10, the first locking part 32 is in the first extended position, at which time the first locking part 32 is inserted into the first locking groove 31. When the operating member 40 is in the operating state, the first locking part 32 is triggered by the operating member 40, and the first locking part 32 can switch to the first retracted position. At this time, the first locking part 32 separates from the first locking groove 31, and the LED display module 20 can be separated from the housing 10. With the above-described configuration, the first disassembly hole 21 extends through the thickness of the LED display module 20, facilitating the insertion of the operating member 40 from either the front or rear of the LED display module 20. This allows the operating member 40 to trigger the first locking part 32, switching it from an extended position to a retracted position. Specifically, the first locking part 32 can separate from the first locking groove 31, allowing the LED display module 20 to separate from the housing 10. Therefore, the first disassembly hole 21 facilitates disassembly of the LED display module 20 from either the front or rear. The anti-detachment structure 50 engages with the operating member 40, preventing the LED display module 20 from easily separating from the operating member 40 when it is in operation. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies that LED display modules can only be disassembled from the front.

[0034] The thickness direction of the LED display module is parallel to the direction from the front side to the rear side of the LED display module.

[0035] The first locking part 32 has a tapered end that inserts into the first locking groove 31, making it easier for the first locking part 32 to be inserted into the first locking groove 31. The first locking part 32 includes a first locking pin, which has a T-shaped structure. The cross-section of the first locking pin can be circular, square, rectangular, or other shapes.

[0036] In other embodiments, a first locking groove 31 is disposed on the housing 10, the first locking groove 31 extends through the thickness direction of the housing 10, and a first locking part 32 is disposed on the LED display module 20.

[0037] In other embodiments, the operating element 40 can be supplied separately.

[0038] like Figure 1 , Figure 3 , Figure 5 as well as Figure 9 As shown, in this embodiment, the anti-detachment structure 50 is movably disposed, and the operating member 40 has a mating portion 43. When the operating member 40 is in the operating state, the anti-detachment structure 50 engages with the mating portion 43 to prevent the LED display module 20 from detaching from the operating member 40. Movement of the anti-detachment structure 50 allows it to either engage with the mating portion 43 or separate from it. When the anti-detachment structure 50 engages with the mating portion 43, the relative position between the operating member 40 and the LED display module 20 remains stable, preventing the LED display module 20 from detaching from the operating member 40. When the anti-detachment structure 50 separates from the mating portion 43, the operating member 40 can be detached from the LED display module 20.

[0039] like Figure 8 and Figure 9As shown, in this embodiment, the mating part 43 includes a groove 431, and the anti-detachment structure 50 includes a first elastic reset member 51 and a second locking part 52. The first elastic reset member 51 applies an elastic force to the second locking part 52 to keep the second locking part 52 within the groove 431. The provision of the first elastic reset member 51 facilitates the movement of the second locking part 52 into the groove 431 and also enables the second locking part 52 to be kept within the groove 431. When it is necessary to separate the operating member 40 from the LED display module 20, a force is applied to the operating member 40 in a direction away from the LED display module 20. As a result, the mating part 43 can press the second locking part 52, and the second locking part 52 can press the first elastic reset member 51, so that the second locking part 52 moves in a direction away from the operating member 40 until the second locking part 52 separates from the groove 431. Then the operating member 40 can be separated from the LED display module 20. That is, by setting the anti-detachment structure 50, a certain force is required to disassemble the operating member 40, avoiding the problem that when the anti-detachment structure 50 is not set, the operating member can slide in the first disassembly hole 21 and the operating member 40 can be separated from the LED display module 20 with a small force.

[0040] In other embodiments, the anti-detachment structure 50 includes a first protrusion disposed within the first disassembly hole 21, while the mating part 43 is not provided. The first protrusion can press against the wall of the first disassembly hole 21 to compress the operating member 40, so that when the operating member 40 is separated from the LED display module 20, a certain amount of pulling force needs to be applied, avoiding the need to use a small force to pull the operating member out of the first disassembly hole 21.

[0041] In other embodiments, the anti-detachment structure 50 includes a second locking part that is movably disposed but will not detach from the LED display module.

[0042] like Figure 3As shown, in this embodiment, the locking structure 30 further includes a second locking groove 33 and a movably disposed third locking part 34. The third locking part 34 is disposed on the housing 10, and the second locking groove 33 is disposed on the LED display module 20. The LED display module 20 is also provided with a second disassembly hole 22, which penetrates the LED display module 20 along its thickness direction and communicates with the second locking groove 33. When the LED display module 20 is installed on the housing 10, the third locking part 34 is in a second extended position inserted into the second locking groove 33. When the operating member 40 is in the operating state, the operating member 40 simultaneously triggers the first locking part 32 and the third locking part 34. The third locking part 34 can switch to a second retracted position separated from the second locking groove 33, so that the LED display module 20 can be separated from the housing 10. The third locking part 34 can switch between the second extended position and the second retracted position, which facilitates the assembly and disassembly of the LED display module 20 from the housing 10. The second disassembly hole 22 allows operators to insert the operating member 40 from either the front or rear of the LED display module 20. The operating member 40 then triggers the third locking part 34, causing it to switch to the second retracted position, thus separating the LED display module 20 from the housing 10. This facilitates disassembly of the LED display module 20 from either the front or rear. The operating member 40 can simultaneously trigger both the first locking part 32 and the third locking part 34, reducing the number of operating members required. A single operating member 40 can unlock both the first and third locking parts 32 and 34 simultaneously, avoiding the need for separate operating members 40 for each part.

[0043] When the operating member 40 is in the operating state, the operating member 40 is simultaneously inserted into the first disassembly hole 21 and the second disassembly hole 22, and simultaneously triggers the first locking part 32 and the third locking part 34. When the operating member 40 is in the disassembly state, the operating member 40 is simultaneously removed from the first disassembly hole 21 and the second disassembly hole 22.

[0044] The third locking part 34 and the first locking part 32 are symmetrically arranged in the height direction of the LED display module 20. The end of the third locking part 34 that inserts into the second locking groove 33 is also tapered, which makes it easier for the third locking part 34 to be inserted into the second locking groove 33. The third locking part 34 includes a second locking pin, which is T-shaped. The cross-section of the second locking pin can be circular, square, rectangular, or other shapes.

[0045] In other embodiments, the second locking groove 33 is disposed on the housing 10, and the third locking part 34 is disposed on the LED display module 20.

[0046] like Figures 3 to 5 As shown, in this embodiment, the locking structure 30 further includes a second elastic reset member 35, which is disposed between the first locking portion 32 and the third locking portion 34. The second elastic reset member 35 can apply an elastic reset force to the first locking portion 32 and the third locking portion 34, so that the first locking portion 32 is held in the first extended position and the third locking portion 34 is held in the second extended position. Disposing the second elastic reset member 35 between the first locking portion 32 and the third locking portion 34 also simplifies the structure of the locking structure 30, avoiding the need to separately provide elastic reset members corresponding to the first locking portion 32 and the third locking portion 34.

[0047] It should be noted that the second elastic reset member 35 includes the first compression spring.

[0048] The housing 10 includes a housing body 11 and a cover 12, with a receiving space formed between the housing body 11 and the cover 12. The first locking part 32, the third locking part 34 and the second elastic reset member 35 are clamped in the receiving space.

[0049] The box body 11 and the cover 12 are connected by fasteners.

[0050] like Figure 8 , Figure 9 as well as Figure 12 As shown, in this embodiment, the operating member 40 includes a first operating piece 41 and a second operating piece 44 connected to the first operating piece 41. When the operating member 40 is in the operating state, the first operating piece 41 is inserted into the first disassembly hole 21 and triggers the first locking part 32, and the second operating piece 44 is inserted into the second disassembly hole 22 and triggers the third locking part 34. The first operating piece 41 has a small thickness, which can adapt to the LED display module 20 with a small pitch of lamp beads.

[0051] like Figure 12 As shown, in this embodiment, the end of the operating member 40 inserted into the first disassembly hole 21 is provided with a guide portion 42. When the operating member 40 switches from the disassembled state to the operating state, the guide portion 42 abuts against the first locking portion 32. The guide portion 42 abuts against the first locking portion 32, allowing the operating member 40 to be inserted between the hole wall of the first disassembly hole 21 and the first locking portion 32. In this way, the guide portion 42 can press the first locking portion 32 to move away from the first locking groove 31, making it easier for the first locking portion 32 to separate from the first locking groove 31.

[0052] It should be noted that the guide portion 42, which is provided at the end of the operating member 40 that is inserted into the first disassembly hole 21, is provided at the end of the first operating piece 41 that is inserted into the first disassembly hole 21.

[0053] The guide section 42 includes a first guide ramp.

[0054] The end of the operating member 40 that is inserted into the second disassembly hole 22 is also provided with a guide portion 42. When the operating member 40 is switched from the disassembled state to the operating state, the guide portion 42 at the end of the operating member 40 that is inserted into the second disassembly hole 22 abuts against the third locking portion 34. This makes it easier for the operating member 40 to be inserted between the hole wall of the second disassembly hole 22 and the third locking portion 34, so that the third locking portion 34 can be more easily separated from the second locking groove 33.

[0055] It should be noted that the guide portion 42, which is provided at the end of the operating member 40 that is inserted into the second disassembly hole 22, is provided at the end of the second operating piece 44 that is inserted into the second disassembly hole 22.

[0056] The operating component of this embodiment can be further applied to the front and rear maintenance of LED display modules 20 with small dot pitch, and the thickness of the operating component 40 can be very small. The first operating piece 41 and the second operating piece 44 have the same thickness, 0.2 mm, which can adapt to LED display modules 20 with small lamp bead pitch, such as P2 dot pitch LED display modules. The first operating piece 41 and the second operating piece 44 have the same structure. The first operating piece 41 and the second operating piece 44 are symmetrically arranged.

[0057] like Figure 12 As shown, in this embodiment, the operating member 40 further includes a gripping portion 45, which is connected between the first operating piece 41 and the second operating piece 44. By gripping the gripping portion 45, the operator can easily operate the operating member 40 to insert the first operating piece 41 into the first disassembly hole 21 and to insert the second operating piece 44 into the second disassembly hole 22, or to separate the first operating piece 41 from the first disassembly hole 21 and to separate the second operating piece 44 from the second disassembly hole 22.

[0058] The first end of the gripping part 45 is connected to the first operating plate 41, and the second end of the gripping part 45 is connected to the second operating plate 44. When the operating member 40 switches from the detached state to the operating state, the operator grips the gripping part 45. The gripping part 45 includes a grip plate. The thickness of the grip plate is the same as the thickness of the first operating plate 41.

[0059] The operating component 40 has a U-shaped structure, with the first operating piece 41, the grip plate, and the second operating piece 44 forming a U-shaped structure.

[0060] The operating component 40 also includes a second guide slope 46 disposed on the first operating piece 41, the second guide slope 46 being located on the side of the first operating piece 41 away from the first locking part 32. The second guide slope 46 is guided and engaged with the anti-disengagement structure 50.

[0061] It should be noted that there are two anti-detachment structures 50, and the two anti-detachment structures 50 respectively correspond to and cooperate with the mating part 43 on the first operating plate 41 and the mating part 43 on the second operating plate 44.

[0062] Two anti-detachment structures are symmetrically arranged.

[0063] The first locking part 32 and the anti-detachment structure 50 corresponding to the first operating piece 41 are located on both sides of the first operating piece 41.

[0064] In other embodiments, the anti-detachment structure 50 may be disposed on the operating member 40, and the mating part 43 may be disposed on the LED display module 20.

[0065] It should be noted that, in this embodiment, the groove 431 is disposed on the first operating piece 41, and the groove 431 is an arc-shaped groove. The groove 431 is disposed on the side of the first operating piece 41 away from the second operating piece 44.

[0066] In other embodiments, the groove 431 may be disposed on one of the two surfaces in the thickness direction of the first operating piece 41, or it may be disposed on the side of the first operating piece 41 near the second operating piece 44.

[0067] The second locking part 52 is inserted into the groove 431 with a rounded transition at one end, which makes it easier for the third locking part 34 to be inserted into the groove 431.

[0068] The second locking part 52 includes a third locking pin, which has a T-shaped structure. The first elastic reset member 51 includes a second compression spring. The cross-section of the third locking pin can be circular, square, rectangular, or other shapes.

[0069] In other embodiments, the mating part 43 may be disposed on the surface of the operating member 40 in the thickness direction, and the anti-detachment structure 50 is disposed corresponding to the mating part 43. That is, at this time, the extension direction of the anti-detachment structure 50 is set at an angle to the extension direction of the first locking part 32. Specifically, the extension direction of the anti-detachment structure 50 is set perpendicular to the extension direction of the first locking part 32.

[0070] In other embodiments, a third guide slope is provided between the side wall of the groove 431 near the end of the operating member 40 that is inserted into the first disassembly hole 21 and the outer surface of the operating member 40. The third guide slope is guided and cooperated with the anti-detachment structure 50, so that the operating member 40 can be more easily separated from the LED display module 20.

[0071] like Figure 3 and Figure 8As shown, in this embodiment, the first locking part 32 is disposed on the housing 10. The LED display module 20 includes a lamp plate 23 and a first connecting seat 24 disposed on the rear side of the lamp plate 23. A first disassembly hole 21 penetrates the lamp plate 23 and the first connecting seat 24. A first locking groove 31 is disposed on the first connecting seat 24. The first connecting seat 24 is also provided with a connecting hole 241. The second locking part 52 passes through the connecting hole 241 and extends into the first disassembly hole 21. The first disassembly hole 21 penetrates the lamp plate 23 and the first connecting seat 24, facilitating the insertion of the operating member 40. The connecting hole 241 facilitates the insertion of the third locking part 34 into the first disassembly hole 21 through the connecting hole 241.

[0072] The first connecting seat 24 is provided with a fourth guide slope 242, which guides and cooperates with the first locking part 32, so that the first locking part 32 can enter the first locking groove 31 more easily.

[0073] The third locking pin cooperates with the first connecting seat 24 to prevent the third locking pin from moving excessively into the connecting hole 241.

[0074] The first locking groove 31 and the connecting hole 241 are connected. The cross-section of the first locking groove 31 and the connecting hole 241 can be circular, or of course, other shapes.

[0075] like Figure 3 As shown, in this embodiment, the LED display module 20 further includes a second connecting seat 25 disposed on the rear side of the lamp panel 23. The second connecting seat 25 is spaced apart from the first connecting seat 24. The first end of the first elastic reset member 51 abuts against the second connecting seat 25, and the second end of the first elastic reset member 51 abuts against the second locking part 52. The spaced-apart arrangement of the second connecting seat 25 and the first connecting seat 24 facilitates the placement of the first elastic reset member 51 and the second locking part 52 between the first connecting seat 24 and the second connecting seat 25.

[0076] The second connecting seat 25 is provided with a mounting hole, and the first elastic reset member 51 is disposed in the mounting hole, with the first end of the first elastic reset member 51 abutting against the wall of the mounting hole. This makes it easier to install the first elastic reset member 51 and the second locking part 52 between the first connecting seat 24 and the second connecting seat 25.

[0077] The LED display module 20 also includes a third connecting seat 26 located on the rear side of the lamp plate 23. A second disassembly hole 22 passes through the lamp plate 23 and the third connecting seat 26. A second locking groove 33 is provided on the third connecting seat 26. An avoidance hole is also provided on the third connecting seat 26. A second locking part 52 passes through the avoidance hole and extends into the second disassembly hole 22.

[0078] The third connector 26 has the same structure as the first connector 24.

[0079] The LED display module 20 also includes a fourth connector 27 located on the rear side of the lamp plate 23, which is spaced apart from the third connector 26. The first end of the first elastic reset member 51, which is corresponding to the second operating piece 44, abuts against the third connector 26, and the second end of the first elastic reset member 51, which is corresponding to the second operating piece 44, abuts against the second locking part 52, which is corresponding to the second operating piece 44.

[0080] The fourth connecting seat 27 has the same structure as the second connecting seat 25.

[0081] The LED display module 20 also includes a housing, with a lamp board 23 disposed on the front side of the housing, and a first connecting seat 24, a second connecting seat 25, a third connecting seat 26, and a fourth connecting seat 27 disposed on the rear side of the housing. A first disassembly hole 21 penetrates the housing, the lamp board 23, and the first connecting seat 24. A second disassembly hole 22 penetrates the housing, the lamp board 23, and the third connecting seat 26. Along the height direction of the LED display module 20, the second connecting seat 25, the first connecting seat 24, the third connecting seat 26, and the fourth connecting seat 27 are arranged sequentially at intervals.

[0082] The LED display device further includes at least one connecting structure. Each connecting structure includes a first disassembly hole 21, a second disassembly hole 22, a first connecting seat 24, a second connecting seat 25, a third connecting seat 26, a fourth connecting seat 27, a locking structure 30, an anti-detachment structure 50 corresponding to the second connecting seat 25, and an anti-detachment structure 50 corresponding to the fourth connecting seat 27. In this embodiment, the LED display module 20 is provided with two connecting structures. The two connecting structures are spaced apart in the height direction of the LED display module 20.

[0083] In other embodiments, the LED display module 20 may have more connection structures, at least three.

[0084] The cover 12 includes multiple parts, including a first locking part 32, a third locking part 34 and a second elastic reset member 35, which are correspondingly provided with one cover 12. That is, each connecting structure is provided with one cover 12.

[0085] The housing body 11 includes a frame and two reinforcing plates 111 connected to the two opposing inner walls of the frame. Each reinforcing plate 111 has at least one cover 12. A first locking part 32, a third locking part 34, and a second elastic reset member 35 are provided between the cover 12 and the corresponding reinforcing plate.

[0086] The LED display module 20 includes multiple LED display modules 20 arranged in an array.

[0087] When installing the LED display module 20: The LED display module 20 is inserted into the housing 10 from the front. When the LED display module 20 is inserted, the first locking part 32 on the housing 10 comes into contact with the fourth guide slope 242 on the LED display module 20 and is squeezed. Under the squeezing action of the fourth guide slope 242, the first locking part 32 on the housing 10 compresses the second elastic reset member 35, so the first locking part 32 moves into the receiving space. After the LED display module 20 is inserted, the first locking part 32 rebounds under the reaction force of the second elastic reset member 35, so the first locking part 32 can be locked into the first locking groove 31 on the LED display module 20. The first locking part 32 and the first locking groove 31 cooperate, and under the action of the force of the second elastic reset member 35, the LED display module 20 is fastened. In this way, the LED display module 20 is successfully inserted and locked on the housing 10.

[0088] When maintaining the LED display module 20 from the rear of the housing 10: From the rear of the housing 10, align the first operating piece 41 with the first disassembly hole 21 of the LED display module 20, insert the first operating piece 41, and the first operating piece 41 will press the first locking part 32 inward, causing the first locking part 32 to disengage from the first locking groove 31 on the LED display module 20. Additionally, the groove 431 on the outer side of the first operating piece 41 will engage with the anti-disengagement structure 50, thus combining the first operating piece 41 with the LED display module 20. The working process of the second operating piece 44 is the same as that of the first operating piece 41. The process is the same. Push the operating component 40 to make the LED display module 20 move away from the housing 10 by a certain distance (because the outer side of the operating component 40 is stuck with the anti-detachment structure 50, the groove 431 of the operating component 40 can limit the LED display module 20 so that the LED display module 20 will not fall directly). Then, hold the operating handle of the LED display module 20 and push it outward with force to overcome the effect of the first elastic reset component 51. The operating component 40 will disengage from the second locking part 52. After disengagement, rotate the LED display module 20 by a certain angle. In this way, the LED display module 20 can be easily removed.

[0089] When maintaining the LED display module from the front of the housing: Align the first operating piece 41 with the first disassembly hole 21 of the LED display module 20 from the front of the housing, insert the first operating piece 41, and the first operating piece 41 will press the first locking part 32 inward, causing the first locking part 32 to disengage from the first locking groove 31 on the LED display module 20. In addition, the groove 431 on the outer side of the first operating piece 41 will engage with the anti-disengagement structure 50, thus combining the first operating piece 41 with the LED display module 20. The working process of the second operating piece 44 is the same as that of the first operating piece 41. Push the operating component 40 to move the LED display module 20 a certain distance away from the housing 10 (because the outer side of the operating component 40 is stuck with the anti-detachment structure 50, the groove 431 of the operating component 40 can limit the LED display module 20 so that the LED display module 20 will not fall directly). Then, hold the operating handle of the LED display module 20 and push it outward forcefully to overcome the effect of the first elastic reset component 51. The operating component 40 will disengage from the second locking part 52. After disengagement, rotate the LED display module 20 at a certain angle. In this way, the LED display module 20 can be easily removed.

[0090] Using the operating component 40 of this embodiment can reduce the number of disassembly and assembly mechanisms for the LED display module 20. Two operating components 40 are sufficient for one LED display module 20, or even just one operating component 40 is needed to disassemble and assemble the LED display module 20.

[0091] In this embodiment, the operating member 40 and the locking structure 30 are pressed in the direction of a straight insertion tangential force, which avoids the phenomenon in the prior art where the rotating mechanism cannot rotate and the teeth strip when applying rotational force because the rotating wrench is very small.

[0092] In this embodiment, both the front and rear maintenance of the LED display module 20 can be completed in one step, making the operation simple.
