Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically to a display screen. Background Technology

[0002] Currently, with the rapid development of the LED industry, outdoor fixed installations of displays are extremely popular. Meanwhile, the industry trend is towards speed, safety, and ease of operation.

[0003] Currently, most outdoor display cabinet modules on the market use a safety rope as their anti-detachment design, with one end attached to the module and the other to the cabinet. If the module uses a magnetic attachment method, the magnetic force weakens over time when exposed to the elements. If the module detaches, it may collide with adjacent modules below, causing damage. Similarly, if the module uses a locking mechanism, it suffers from the same drawback. During front-maintenance installation, the safety rope may be left unattached, leading to serious safety accidents or damage to other modules on the screen after detachment, affecting display quality. Utility Model Content

[0004] The purpose of this invention is to provide a display screen that optimizes the structure of the display screen in related technologies to improve the reliability of the connection between the cabinet and the display module.

[0005] To solve the above-mentioned technical problems, this utility model provides a display screen, comprising: a housing; a display module connected to one side of the housing; and an anti-detachment structure disposed between the housing and the display module. The anti-detachment structure includes: a fixing member fixed to the side of the display module facing the housing, the fixing member having a groove on its side wall, and an installation opening at the end of the groove away from the display module; the groove including a snap-fit ​​section and a release section, the snap-fit ​​section communicating with the release section; and a sleeve fixed to the housing. The connecting shaft is slidably inserted into the sleeve; the connecting shaft is rotatably disposed in the sleeve; a locking post is provided at one end of the connecting shaft near the display module; wherein, the locking post can enter the release section through the mounting port, the locking post can rotate from the release section into the locking section and lock into the locking section to realize the connection between the housing and the display module; the locking post can rotate from the locking section into the release section and can disengage from the fixing member through the release section and the mounting port to realize the disengagement between the housing and the display module.

[0006] In some embodiments, the fixing member is provided with a receiving groove, the receiving groove being open toward the housing; one end of the connecting shaft near the display module can extend into the receiving groove through the opening; the connecting shaft is rotatably disposed in the receiving groove; the sliding groove is formed on the side wall of the fixing member corresponding to the receiving groove.

[0007] In some embodiments, the fastener has a mating portion on the side wall facing the display module, and the surface of the display module has a mating groove, wherein the mating portion and the mating groove are detachably connected.

[0008] In some embodiments, the end of the latching section away from the disengaging section is provided with a latching position, and the latching post can be latched into the latching position.

[0009] In some embodiments, a limiting groove is provided on the outer peripheral wall of the connecting shaft, and a limiting plunger is provided on the sleeve. The limiting plunger slides within the limiting groove to allow the snap-fit ​​pin to enter or disengage from the disengagement section through the mounting port. A first snap-fit ​​and a second snap-fit ​​are respectively provided at both ends of the limiting groove, and the first and second snap-fits extend along the rotation direction of the connecting shaft. When the limiting plunger slides to the end of the limiting groove away from the display module, the limiting plunger can rotate from one end of the limiting groove into the first snap-fit, allowing the snap-fit ​​pin to simultaneously rotate from the snap-fit ​​section into the disengagement section. When the limiting plunger slides to the end of the limiting groove close to the display module, the limiting plunger can rotate from the other end of the limiting groove into the second snap-fit, allowing the snap-fit ​​pin to enter the disengagement section through the mounting port.

[0010] In some embodiments, a mounting hole is provided on the peripheral sidewall of the sleeve, the limiting plunger is fixed at the mounting hole, and one end of the limiting plunger can extend into the sleeve through the mounting hole and slide to connect with the limiting groove.

[0011] In some embodiments, a fixing ring is fixed on the housing, the fixing ring has a through hole in the middle, and the sleeve passes through the through hole; the sleeve has a fixing plate, and the fixing plate is fixedly connected to the fixing ring.

[0012] In some embodiments, the display screen further includes an elastic element sleeved on the connecting shaft; the sleeve has a guide groove, one end of the elastic element extends into the guide groove and abuts against the bottom wall of the guide groove, and the other end of the elastic element abuts against the connecting shaft.

[0013] In some embodiments, a baffle is provided at one end of the connecting shaft away from the display module, the baffle being able to cover the opening of the guide groove, and the end of the elastic member away from the guide groove abutting against the baffle.

[0014] In some embodiments, the slide groove is provided in two sets, and the two sets of slide grooves are rotationally symmetrical about the axis of the fixing member; the snap-fit ​​post is provided in two sets, and the two snap-fit ​​posts are respectively provided on opposite sides of the connecting shaft.

[0015] As can be seen from the above technical solution, this utility model has at least the following beneficial effects: This utility model provides a display screen, which may include a housing, a display module, and an anti-detachment structure. The anti-detachment structure includes a fixing member, a sleeve, and a connecting shaft. A locking post can extend into the release section of a sliding groove through an installation port and slide along the release section. The locking post can slide along the release section to a position where the release section and the locking section connect. At this point, rotating the connecting shaft in the forward direction causes the locking post to rotate synchronously in the forward direction, thereby allowing the locking post to rotate and engage within the locking section. This achieves the connection between the locking section and the fixing member, and thus the connection between the display module and the housing. This prevents the display module from detaching from the housing, thereby improving the reliability of the connection between the housing and the display module. Meanwhile, when the user needs to disassemble the display module, the user can rotate the connecting shaft in the opposite direction, so that the connecting shaft can drive the locking pin to rotate in the opposite direction synchronously. This allows the locking pin to rotate from the locking section to the disengagement section. At this time, the display module can move away from the cabinet under the action of external force, which drives the fixing part to move away from the cabinet. This causes the locking pin to disengage from the fixing part from the disengagement section and the mounting port, thereby realizing the disengagement of the cabinet from the display module, which makes it convenient for the user to replace and repair the display module.

[0033] Currently, most outdoor display cabinet modules on the market use a safety rope as their anti-detachment design, with one end attached to the module and the other to the cabinet. If the module uses a magnetic attachment method, the magnetic force weakens over time when exposed to the elements. If the module detaches, it may collide with adjacent modules below, causing damage. Similarly, if the module uses a locking mechanism, it suffers from the same drawback. During front-maintenance installation, the safety rope may be left unattached, leading to serious safety accidents or damage to other modules on the screen after detachment, affecting display quality.

[0034] Figure 1 This is a structural schematic diagram of an embodiment of the display screen 100 of this utility model. Figure 2 yes Figure 1 The exploded diagram. Figure 3 This is a schematic diagram of the structure of display module 2.

[0035] Please see Figures 1 to 3 As shown, in some embodiments, the display screen 100 provided by the present invention includes multiple display units. The multiple display units can be arranged in a spliced ​​manner. Each display unit may include a housing 1 and a display module 2 disposed on the housing 1.

[0036] In some embodiments, multiple boxes 1 may be provided, and the multiple boxes 1 may be arranged in a spliced ​​manner. The multiple boxes 1 may be arranged in a rectangular array or the like.

[0037] It should be noted that in some other embodiments, the multiple boxes 1 may also be arranged in a polygonal or other shape.

[0038] In some embodiments, multiple display modules 2 may be provided. The multiple display modules 2 can be arranged in a one-to-one correspondence with multiple cabinets 1, that is, each cabinet 1 is equipped with one display module 2. The display modules 2 can be installed on one side of the cabinet 1. The multiple display modules 2 can be arranged in a rectangular array. The distance between each display module 2 and the cabinet 1 is equal, so that the side of the multiple display modules 2 facing away from the cabinet 1 can form a flat display surface.

[0039] It should be noted that in some other embodiments, each housing 1 may also be equipped with multiple display modules 2.

[0040] It should also be noted that in some other embodiments, the multiple display modules 2 may be arranged in a polygonal or other shape.

[0041] Please see Figure 2 As shown, in some embodiments, the display screen 100 may include an anti-detachment structure 3. The anti-detachment structure 3 may be disposed between the display module 2 and the housing 1. The anti-detachment structure 3 is used to prevent loosening, detachment, or misalignment between the display module 2 and the housing 1 under external force or long-term use, thereby ensuring the functionality, stability, and safety of the display screen 100. Simultaneously, the anti-detachment structure 3 can be detachably disposed between the display module 2 and the housing 1, allowing the user to remove the display module 2 from the housing 1, improving the maintenance efficiency of the display module 2.

[0042] Figure 4 yes Figure 2 A schematic diagram of the anti-hair loss structure 3. Figure 5 yes Figure 4 A structural diagram from another perspective. Figure 6 yes Figure 2 Enlarged view of section A.

[0043] Please see Figures 2 to 6 As shown, in some embodiments, the anti-detachment structure 3 may include a fixing member 31 and a connecting component. One end of the fixing member 31 can be fixed to the display module 2, and the other end of the fixing member 31 can be detachably connected to the connecting component. The connecting component can be fixed to the display module 2, thereby enabling the detachable connection between the display module 2 and the housing 1 through the detachable connection between the fixing member 31 and the connecting component.

[0044] In some embodiments, a first fixing hole 311 may be provided on the fixing member 31. The first fixing hole 311 may extend through the middle of the fixing member 31. A second fixing hole 21 may be provided on one side surface of the display module 2. The second fixing hole 21 may be provided on the back side of the display module 2. The second fixing hole 21 may be arranged opposite to the first fixing hole 311, so that the fixing member 31 and the display module 2 can be fixedly connected through the first fixing hole 311 and the second fixing hole 21.

[0045] In some embodiments, the second fixing hole 21 can be a threaded hole. A bolt can pass through the first fixing hole 311 and be threaded into the second fixing hole 21. Therefore, using bolts to connect the fixing member 31 and the display module 2 can improve the stability of the connection between the fixing member 31 and the display module 2.

[0046] In some embodiments, the fixing member 31 may be provided with a mating portion 312. The mating portion 312 may protrude from the side wall of the fixing member 31 near the display module 2. A mating groove 22 may be provided on the surface of the display module 2. The mating groove 22 can be adapted to the mating portion 312. The mating portion 312 can be detachably connected to the mating groove 22. The mating portion 312 on the fixing member 31 can extend into and mat with the mating groove 22, thereby realizing the mating and positioning of the fixing member 31 and the display module 2, thereby improving the installation efficiency of the fixing member 31 on the display module 2. Furthermore, by using the mating portion 312 to extend into and mat with the mating groove 22, the fixing member 31 can be limited, preventing the fixing member 31 from rotating relative to the display module 2, thus improving the installation stability of the fixing member 31 on the display module 2.

[0047] Please see Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the connecting component can be fixed to the housing 1. One end of the connecting component can pass through the housing 1 and be detachably connected to the fastener 31 to achieve a detachable connection between the housing 1 and the fastener 31, thereby achieving a detachable connection between the housing 1 and the display module 2.

[0048] Figure 7 yes Figure 5 The exploded diagram.

[0049] Please see Figures 5 to 7As shown, in some embodiments, the connecting assembly may include a sleeve 32 and a connecting shaft 33. The sleeve 32 can be fixed to the housing 1, and the connecting shaft 33 can slide through the sleeve 32. One end of the connecting shaft 33 passing through the sleeve 32 can be detachably connected to the fixing member 31. Thus, by utilizing the cooperation between the connecting shaft 33 and the fixing member 31, the connection between the housing 1 and the display module 2 can be realized, improving the reliability of the connection between the housing 1 and the display module 2. It also allows for the detachment of the housing 1 and the display module 2, thereby facilitating the user's replacement and maintenance of the display module 2.

[0050] In some embodiments, the housing 1 may be provided with a retaining ring 11. A sleeve 32 can be fixedly connected to the retaining ring 11.

[0052] Please participate Figures 8 to 10As shown, in some embodiments, a groove 313 may be provided on the side wall of the fixing member 31. A mounting port 3131 is provided at the end of the groove 313 away from the display module 2. The groove 313 can communicate with the external space of the groove 313 through the mounting port 3131. The groove 313 may include a snap-fit ​​section 3133 and a release section 3132. The snap-fit ​​section 3133 can communicate with the release section 3132. A snap-fit ​​post 331 is provided at the end of the connecting shaft 33 near the display module 2. The snap-fit ​​post 331 can extend into the release section 3132 of the slide groove 313 through the mounting port 3131 and slide along the release section 3132. The snap-fit ​​post 331 can slide along the release section 3132 to the position where the release section 3132 and the snap-fit ​​section 3133 are connected. At this time, the connecting shaft 33 is rotated in the forward direction, and the connecting shaft 33 can drive the snap-fit ​​post 331 to rotate synchronously in the forward direction, so that the snap-fit ​​post 331 can rotate and snap into the snap-fit ​​section 3133, so as to realize the connection between the snap-fit ​​section 3133 and the fixing member 31, thereby realizing the connection between the display module 2 and the cabinet 1, thus preventing the display module 2 from separating from the cabinet 1, and thus improving the reliability of the connection between the cabinet 1 and the display module 2. Meanwhile, when the user needs to disassemble the display module 2, the user can rotate the connecting shaft 33 in the opposite direction, so that the connecting shaft 33 can drive the locking post 331 to rotate in the opposite direction synchronously, so that the locking post 331 can rotate from the locking section 3133 to the disengagement section 3132. At this time, the display module 2 can move away from the cabinet 1 under the action of external force, driving the fixing part 31 to move away from the cabinet 1, and causing the locking post 331 to disengage from the fixing part 31 from the disengagement section 3132 and the mounting port 3131, thereby realizing the disengagement of the cabinet 1 from the display module 2, which makes it convenient for the user to replace and repair the display module 2.

[0053] In some embodiments, two sets of slide grooves 313 may be provided. The two sets of slide grooves 313 may be rotationally symmetrical about the axis of the fixing member 31, and two locking posts 331 may be provided, with the two locking posts 331 respectively located on opposite sides of the connecting shaft 33. The two locking posts 331 can be arranged opposite to the two slide grooves 313 respectively, thereby improving the stability of the connection between the locking posts 331 and the fixing member 31 by simultaneously engaging the two slide grooves 313 with the two locking posts 331.

[0054] In some embodiments, the slide 313 may be L-shaped. When the user needs to disassemble the display module 2, the user can apply a force away from the housing 1 to the display module 2, causing the display module 2 to move away from the housing 1. The direction of extension of the disengagement section 3132 is the same as the direction of movement of the display module 2, so that when the display module 2 drives the fixing member 31 to move away from the housing 1, the locking post 331 is locked in the locking section 3133, which can prevent the display module 2 from separating from the housing 1, thereby improving the reliability of the connection between the housing 1 and the display module 2.

[0055] In some embodiments, the snap-fit ​​section 3133 may extend along the rotation direction of the connecting shaft 33. When the user needs to replace or repair the display module 2, the user can rotate the connecting shaft 33, causing the snap-fit ​​post 331 to rotate synchronously. This causes the snap-fit ​​post 331 to move along the snap-fit ​​section 3133 and rotate from the snap-fit ​​section 3133 into the disengagement section 3132. At this time, the display module 2 is subjected to a force away from the housing 1, causing the snap-fit ​​post 331 to disengage from the fastener 31 through the disengagement section 3132 and the mounting port 3131, thereby achieving the disengagement of the housing 1 from the display module 2. In some embodiments, the end of the latching segment 3133 away from the disengagement segment 3132 is provided with a latching position 3134. The latching position 3134 may be formed by recessing the end of the latching segment 3133 away from the disengagement segment 3132 in a direction away from the display module 2. The latching post 331 can be latched in the latching position 3134, improving the stability of the latching post 331 in the latching segment 3133, preventing the latching post 331 from disengaging from the latching segment 3133 without rotating the connecting shaft 33, thereby improving the stability of the latching between the latching post 331 and the latching segment 3133.

[0056] In some embodiments, the fixing member 31 may be provided with a receiving groove 314. The receiving groove 314 may open toward the housing 1. One end of the connecting shaft 33 near the display module 2 may extend into the receiving groove 314 through the opening. The connecting shaft 33 may be rotatably disposed in the receiving groove 314. A sliding groove 313 may be formed on the side wall of the receiving groove 314 corresponding to the fixing member 31. Thus, the receiving groove 314 can accommodate the rotating connecting shaft 33, thereby allowing the locking pin 331 to rotate synchronously within the sliding groove 313.

[0057] In some embodiments, a through hole 323 may be provided on the side wall of the sleeve 32. The connecting shaft 33 may extend along the moving direction of the display module 2. The connecting shaft 33 may slidably pass through the through hole 323 into the sleeve 32. A locking post 331 may be provided on the peripheral side wall of the connecting shaft 33. The locking post 331 may abut against the peripheral edge of the through hole 323 to prevent the locking post 331 from passing through the through hole 323, thereby limiting the sliding of the connecting shaft 33.

[0058] In some embodiments, a baffle 332 is provided at the end of the connecting shaft 33 away from the locking post 331. The baffle 332 can abut against the peripheral edge of the through hole 323, thereby preventing the baffle 332 from passing through the through hole 323, thereby limiting the sliding of the connecting shaft 33 and preventing the connecting shaft 33 from disengaging from the sleeve 32 under the action of the fixing member 31.

[0059] In some embodiments, the display screen 100 may include an elastic element 34. The elastic element 34 may be sleeved on the connecting shaft 33. A guide groove 320 may be provided inside the sleeve 32. One end of the elastic element 34 can extend into the guide groove 320 and abut against the bottom wall of the guide groove 320, while the other end of the elastic element 34 can abut against the connecting shaft 33, thereby enabling the elastic element 34 to extend and retract on the connecting shaft 33. The guide groove 320 can guide the extension and retraction of the elastic element 34, thereby improving the stability of the elastic element 34 during extension and retraction.

[0060] In some embodiments, the end of the elastic member 34 near the display module 2 abuts against the bottom wall of the guide groove 320, and the end of the elastic member 34 away from the display module 2 abuts against the baffle 332. When the user applies a force to the display module 2 away from the housing 1, the display module 2 can drive the fixing member 31 to move away from the housing 1. Thus, the fixing member 31 can drive the locking pin 331 to move away from the housing 1 via the locking section 3133, thereby driving the connecting shaft 33 to move away from the housing 1. This causes the elastic member 34 to be compressed by the connecting shaft 33, allowing the elastic member 34 to apply a reverse force to the connecting shaft 33, thereby making the locking pin 331 more stably locked within the locking section 3133.

[0061] Figure 11 yes Figure 5 A structural schematic diagram of another embodiment. Figure 12 yes Figure 11 The exploded diagram. Figure 13 yes Figure 12 A schematic diagram of the connecting shaft 33.

[0062] Please see Figures 11 to 13 As shown, in some embodiments, a limiting groove 333 may be provided on the outer peripheral wall of the connecting shaft 33. The extending direction of the limiting groove 333 may be the same as the extending direction of the connecting shaft 33. A limiting plunger 35 may be provided on the sleeve 32. The limiting plunger 35 can slide and limit within the limiting groove 333, so that the locking pin 331 can enter or disengage from the disengagement section 3132 through the mounting port 3131. Thus, by using the limiting plunger 35 to slide and limit the limiting groove 333, the movement of the connecting shaft 33 is more accurate, preventing the connecting shaft 33 from rotating within the disengagement section 3132, thereby improving the stability of the connecting shaft 33 during movement.

[0063] In some embodiments, the two ends of the limiting groove 333 may be respectively provided with a first latch 334 and a second latch 335. The first latch 334 and the second latch 335 can extend along the rotation direction of the connecting shaft 33. The first latch 334 may be located at the end of the limiting groove 333 away from the display module 2. The second latch 335 may be located at the end of the limiting groove 333 near the display module 2. The extending direction of the first latch 334 and the extending direction of the second latch 335 may be opposite.

[0064] In some embodiments, when the user needs to disassemble the display module 2 and move it away from the housing 1, the fixing member 31 can drive the connecting shaft 33 to move synchronously, so that the limiting plunger 35 slides the limiting groove 333 to one end away from the display module 2. At this time, the connecting shaft 33 is rotated so that the limiting plunger 35 can be rotated from one end of the limiting groove 333 into the first bayonet 334, and the locking post 331 can be rotated from the locking section 3133 into the disengagement section 3132, thereby allowing the fixing member 31 to move relative to the locking post 331, thereby realizing the disengagement of the fixing member 31 and the connecting shaft 33, and thus realizing the disengagement of the display module 2 and the housing 1.

[0065] In some embodiments, when the display module 2 is disengaged from the housing 1 and the limiting plunger 35 is located in the first bayonet 334, the elastic member 34 is in a compressed state. At this time, when the connecting shaft 33 is rotated to make the limiting plunger 35 return from the first bayonet 334 to the limiting groove 333, the elastic member 34 can drive the connecting shaft 33 to move away from the sleeve 32 and complete the reset. At this time, the limiting plunger 35 can be located at one end of the limiting groove 333 near the display module 2.

[0066] In some embodiments, when the user needs to reinstall the display module 2, the limiting plunger 35 is located at one end of the limiting groove 333 near the display module 2. When the connecting shaft 33 is rotated, the limiting plunger 35 can rotate from the end of the limiting groove 333 near the sleeve 32 into the second bayonet 335, allowing the locking pin 331 to enter the disengagement section 3132 from the mounting port 3131 and slide to the connection point between the disengagement section 3132 and the locking section 3133. Then, by rotating the connecting shaft 33 in the opposite direction, the limiting plunger 35 can return to the limiting groove 333, allowing the locking pin 331 to rotate into the locking section 3133, thus achieving the locking of the locking pin 331 with the locking section 3133.

[0067] In some embodiments, a mounting hole 324 is provided on the peripheral sidewall of the sleeve 32, and a limiting plunger 35 is fixed at the mounting hole 324. One end of the limiting plunger 35 can extend into the sleeve 32 through the mounting hole 324 and slide to connect with the limiting groove 333.

[0068] As can be seen from the above technical solution, this utility model has at least the following beneficial effects: This utility model provides a display screen 100, which may include a housing 1, a display module 2, and an anti-detachment structure 3. The anti-detachment structure 3 includes a fixing member 31, a sleeve 32, and a connecting shaft 33. The locking post 331 can extend into the disengagement section 3132 of the slide groove 313 through the mounting port 3131 and can slide along the disengagement section 3132. The locking post 331 can slide along the disengagement section 3132 to the position where the disengagement section 3132 and the locking section 3133 are connected. At this time, the connecting shaft 33 is rotated in the forward direction, and the connecting shaft 33 can drive the locking post 331 to rotate synchronously in the forward direction, so that the locking post 331 can rotate and lock into the locking section 3133, thereby realizing the connection between the locking section 3133 and the fixing member 31, and thus realizing the connection between the display module 2 and the housing 1. This can prevent the display module 2 from detaching from the housing 1, thereby improving the reliability of the connection between the housing 1 and the display module 2. Meanwhile, when the user needs to disassemble the display module 2, the user can rotate the connecting shaft 33 in the opposite direction, so that the connecting shaft 33 can drive the locking post 331 to rotate in the opposite direction synchronously, so that the locking post 331 can rotate from the locking section 3133 to the disengagement section 3132. At this time, the display module 2 can move away from the cabinet 1 under the action of external force, driving the fixing part 31 to move away from the cabinet 1, and causing the locking post 331 to disengage from the fixing part 31 from the disengagement section 3132 and the mounting port 3131, thereby realizing the disengagement of the cabinet 1 from the display module 2, which makes it convenient for the user to replace and repair the display module 2.
