Description

Technical Field

[0001] This utility model belongs to the field of LED transparent display screens, and specifically relates to a maintenance lock for LED transparent display screens. Background Technology

[0002] LED displays are widely used in rooftops, commercial performances, advertising, and other occasions due to their excellent display effects. Large-scale splicing screens are generally composed of multiple independent display components.

[0003] Chinese Patent No. CN218992826U discloses a quick-installation locking device for LED transparent displays, including a mounting plate and a connecting plate. The front surface of the connecting plate has a guide hole along its length. A fixing post is connected to the center of the rear end of the mounting plate. A clamping plate is connected to the end of the fixing post through the guide hole. A pressing sleeve is fitted onto the fixing post at the front end of the connecting plate. A fastening spring is abutting between the end face of the pressing sleeve and the mounting plate, pressing the pressing sleeve against the front face of the connecting plate. Simultaneously, the clamping plate abuts against the rear end face of the connecting plate. The mounting plate is connected and fixed to the display screen. The mounting plate is connected and fixed using the connecting plate to splice and fix the display screen. The mounting plate slides along the guide hole of the connecting plate using the fixing post to adjust the display screen spacing. The fastening spring pushes the pressing sleeve against the front face of the connecting plate. Simultaneously, the connecting plate pushes the mounting plate and pulls the clamping plate via the fixing post. The clamping plate abuts against the rear end face of the connecting plate. The pressing sleeve, together with the clamping plate, clamps and fixes the connecting plate.

[0004] In practical use, the existing technology described above uses a fixed column that slides within a connecting plate to adjust the distance between the LED transparent displays and arrange them accordingly. However, when one of the LED transparent displays is damaged and needs repair, each LED transparent display needs to be slid out of the connecting plate one by one, which is inconvenient for disassembly and repair. Therefore, a locking mechanism for maintaining LED transparent displays is needed.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a maintenance lock for LED transparent displays.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A maintenance lock for an LED transparent display screen includes a connecting plate and an LED transparent display screen, with a snap-fit ​​component provided between the connecting plate and the LED transparent display screen;

[0009] The snap-fit ​​assembly includes a limiting plate that slides inside the connecting plate, a fixed cylinder installed at one end of the limiting plate, a support rod installed on one side of the LED transparent display screen, a top column installed on the support rod, a U-shaped frame that slides inside both sides of the fixed cylinder, a top plate that slides inside the fixed cylinder, and a first reset component installed between the top plate and the bottom of the inner wall of the fixed cylinder. The top column cooperates with the U-shaped frame and the top plate, and the top column slides inside the fixed cylinder with the support rod.

[0010] Optionally, a first groove is provided on one side of the connecting plate, and the limiting plate slides inside the first groove. A circular groove is provided on the top of the inner wall of the first groove, and the limiting plate slides inside the circular groove. A threaded rod is installed between the fixed cylinder and the limiting plate, and the threaded rod slides inside the first groove and the circular groove. A threaded cylinder is threaded onto the threaded rod, and the threaded cylinder cooperates with the connecting plate.

[0011] Optionally, the inner sides of the fixed cylinder are provided with second sliding grooves, and two third sliding grooves are provided on one side of the inner wall of each second sliding groove. The U-shaped frame slides and engages inside the second and third sliding grooves. Multiple second reset components are installed between the inner wall of the second sliding groove and the U-shaped frame.

[0012] Optionally, guide grooves are provided on both sides of the inner wall of the fixed cylinder, and guide sliders are installed on opposite sides of the top plate, with the guide sliders slidingly engaged inside the guide grooves.

[0013] Optionally, a support column is installed between one side of the LED transparent display screen and the support rod.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] The sliding fixed cylinder drives the limiting plate to slide inside the connecting plate, facilitating the adjustment of the distance between the LED transparent displays. When connecting the LED transparent displays to the connecting plate, the top post on the support rod is aligned with the fixed cylinder and inserted, so that the lower side of the top post contacts the inclined surface of the two U-shaped frames. This causes the two U-shaped frames to be pressed and move outward. At the same time, the top plate and the lower side of the top post are in contact and press the first reset component. After the top post is inserted into the corresponding position, the inner wall of the two U-shaped frames will abut against the upper side of the top post, thus facilitating the connection between the LED transparent displays and the connecting plate. When disassembling and repairing the LED transparent displays, pressure is applied to the LED transparent displays, and the top post on the support rod will move downward, causing the U-shaped frames to slide outward toward the fixed cylinder, disengaging from the top post. At the same time, under the elastic force of the first reset component, the top plate moves upward, pushing the top post outward, thereby causing the support rod and top post to exit from the fixed cylinder, completing the unlocking process, thus facilitating the disassembly and repair of the LED transparent displays.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this embodiment provides a maintenance lock for an LED transparent display screen, including a connecting plate 1 and an LED transparent display screen 2, with a snap-fit ​​component provided between the connecting plate 1 and the LED transparent display screen 2;

[0027] The snap-fit ​​assembly includes a limiting plate 5 that slides inside the connecting plate 1, a fixing cylinder 10 installed at one end of the limiting plate 5, a support rod 17 installed on one side of the LED transparent display screen 2, a top post 18 installed on the support rod 17, a U-shaped frame 13 that slides inside both sides of the fixing cylinder 10, a top plate 15 that slides inside the fixing cylinder 10, and a first reset member 16 installed between the top plate 15 and the bottom of the inner wall of the fixing cylinder 10. The top post 18 cooperates with the U-shaped frame 13 and the top plate 15, and the top post 18 slides inside the fixing cylinder 10 with the support rod 17.

[0028] One application of this embodiment is: by sliding the limiting plate 5 inside the connecting plate 1, it drives the fixed cylinder 10 to move, so that the distance between them can be adjusted according to the different sizes of LED transparent display screens 2. When it is necessary to snap the connecting plate 1 and the LED transparent display screen 2 together, push the LED transparent display screen 2 so that the support rod 17 and the top column 18 are inserted into the fixed cylinder 10. As the top post 18 is inserted deeper, it comes into contact with and pushes the U-shaped frame 13 and the top plate 15. The top post 18 pushes the top plate 15 downward, compressing the first reset member 16. At the same time, the top post 18 pushes the U-shaped frame 13 to slide to both sides of the fixed cylinder 10. When the top post 18 moves to the appropriate position, the U-shaped frame 13 will lock in a specific position of the top post 18, thereby restricting the movement of the top post 18 and realizing the locking and fixing of the connecting plate 1 and the LED transparent display screen 2. When it is necessary to release the locking for maintenance or other operations of the LED transparent display screen, pressure is applied to the LED transparent display screen 2, and the top post 18 on the support rod 17 will move downward, causing the U-shaped frame 13 to slide outward in the direction of the fixed cylinder 10, releasing the locking of the top post 18. At the same time, under the elastic force of the first reset member 16, the top plate 15 moves upward, pushing the top post 18 outward, thereby causing the support rod 17 and the top post 18 to exit from the fixed cylinder 10, thus unlocking them and allowing the LED transparent display screen to be disassembled and repaired.

[0029] In this embodiment, a first groove 3 is provided on one side of the connecting plate 1, and the limiting plate 5 is slidably engaged inside the first groove 3. A circular groove 4 is provided on the top of the inner wall of the first groove 3, and the limiting plate 5 is slidably engaged inside the circular groove 4. A threaded rod 7 is installed between the fixing cylinder 10 and the limiting plate 5, and the threaded rod 7 is slidably engaged inside the first groove 3 and the circular groove 4. A threaded cylinder 6 is threadedly engaged on the threaded rod 7, and the threaded cylinder 6 is engaged with the connecting plate 1.

[0030] By aligning the limiting disc 5 with the circular groove 4 and inserting it into the interior of the first sliding groove 3 and making it fit against the inner wall, the sliding disc 5 is then moved by the sliding 10 to slide inside the first sliding groove 3, thereby adjusting the position between the fixing cylinder 10 and the fixing cylinder 10. This facilitates the adjustment of LED transparent display screens 2 of different sizes. Then, the operator rotates the threaded cylinder 6, causing it to rotate along the thread of the threaded rod 7, so that one side of the threaded cylinder 6 fits against one side of the connecting plate 1, thus facilitating fixation. By performing the above reverse operation, the fixation of the fixing cylinder 10 can be released and the spacing can be adjusted, thereby preventing relative displacement between the two during use.

[0031] In this embodiment, the fixed cylinder 10 has a second sliding groove 11 on both sides inside. Two third sliding grooves 12 are opened on one side of the inner wall of the second sliding groove 11. The U-shaped frame 13 slides and fits inside the second sliding groove 11 and the third sliding groove 12. Multiple second reset members 14 are installed between the inner wall of the second sliding groove 11 and the U-shaped frame 13.

[0032] When connecting plate 1 and LED transparent display screen 2 are to be snapped together, push LED transparent display screen 2 so that the top post 18 on the support rod 17 on one side is inserted into the fixed cylinder 10. After the top post 18 enters the fixed cylinder 10, it will contact the top plate 15 and push it downward, compressing the first reset member 16 installed between the top plate 15 and the bottom of the inner wall of the fixed cylinder 10. The first reset member 16 and the second reset member 1 can be any one of spring or flexible sheet. At the same time, the top post 18 will contact the U-shaped frame 13 and push it. The U-shaped frame 13 slides within the second slide groove 11 and the third slide groove 12 as it slides to both sides of the fixed cylinder 10. Since multiple second reset members 14 are installed between the inner wall of the second slide groove 11 and the U-shaped frame 13, the second reset members 14 retract when the U-shaped frame 13 slides to both sides. When the top column 18 moves to the appropriate position, the U-shaped frame 13 is locked in a specific position of the top column 18 under the elastic force of the second reset members 14, restricting the movement of the top column 18, thereby realizing the locking and fixing of the connecting plate 1 and the LED transparent display screen 2.

[0033] In this embodiment, the inner wall of the fixed cylinder 10 is provided with guide grooves 20 on both sides, and the top plate 15 is provided with guide sliders 19 on opposite sides. The guide sliders 19 are slidably fitted inside the guide grooves 20.

[0034] The guide groove 20 and guide slider 19 improve the accuracy and stability of the movement of the top plate 15, thereby enhancing the reliability and stability of the entire snap-fit ​​assembly.

[0035] In this embodiment, a support column 8 is installed between one side of the LED transparent display screen 2 and the support rod 17.

[0036] Support column 8 continuously provides stable support for the entire connection structure.
