It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Folding LED billboard, including

[0026] The frame 1 has an opening 11 on the top and a support column 12 inside;

[0027] A movable frame 2, which is movably arranged relative to the frame 1, and a first billboard 21 is provided on the front of the movable frame 2, and a second billboard 22 is provided on the back;

[0028] A lifting mechanism 3, which is used to drive the movable frame 2 to move up and down, so as to be lifted out of the frame 1 from the opening 11 or retracted into the frame 1;

[0029] The transverse movement mechanism 4 is disposed between the movable frame 2 and the second billboard 22 , so as to allow the second billboard 22 to move transversely relative to the movable frame 2 .

[0030] The utility model provides a foldable LED billboard. When displaying advertisements, the movable frame is lifted out from the opening by the lifting mechanism, and then the second billboard is driven to move horizontally by the horizontal movement mechanism, so that the first billboard and the second billboard are displayed side by side. When not in use, the first billboard and the second billboard are stored in the frame for protection to prevent damage or posting of small advertisements or graffiti.

[0031] Further, as a preferred embodiment of the present invention but not a limitation, the second billboard 22 is moved between the display position and the folded position by the lateral movement mechanism 4. When the second billboard 22 is in the display position, it is placed side by side with the first billboard 21. When the second billboard 22 is in the folded position, it is overlapped with the first billboard 21 front and back. This arrangement can save space and display more advertisements. Advertisements can be displayed on both the front and back of the first billboard and the second billboard.

[0032] Further, as a preferred embodiment of the present invention but not limiting, a cover plate 23 is provided on the top of the movable frame 2, and the movable frame 2 is moved between the raised position and the storage position by the lifting mechanism 3, and when the movable frame 2 is in the storage position, the cover plate 23 covers the opening 11. After covering, effective protection can be provided.

[0033] Further, as a preferred embodiment of the present invention but not limiting, the lifting mechanism 3 includes a lifting slide bar 31 provided on the support column 12, a lifting rack 32 provided on the lifting slide bar 31, a lifting drive assembly 33 for driving the lifting rack 32 to move, and a lifting slider 34 provided on the movable frame 2 and slidably matched with the lifting slide bar 31. The lifting slide bar and the lifting slider are conducive to improving the stability of the lifting and lowering.

[0034] Further, as a preferred embodiment of the present invention but not limiting, the lifting drive assembly 33 includes a rotating shaft 331, a lifting gear 332 disposed on the rotating shaft 331 and meshing with the lifting rack 32, a sprocket 333 disposed on the rotating shaft 331, a chain 334 matched with the sprocket 333, and a linear motor driving the chain 334. The rotating shaft extends to both sides of the movable frame. The sprocket is not easy to slip, and is safe and reliable.

[0035] Furthermore, as a preferred embodiment of the present invention but not a limitation, the linear motor includes a linear rail 337, a linear slider 338 disposed on the linear rail 337, and a clamping member 336 disposed on the linear slider 338, and the linear slider 338 and the clamping member 336 clamp the chain 334.

[0036] Further, as a preferred embodiment of the present invention but not limiting, the transverse movement mechanism 4 includes a transverse movement track 41 provided on the movable frame 2, and a transverse movement slider 42 provided on the second billboard 22. The second billboard can be manually pulled.

[0037] Furthermore, as a preferred embodiment of the present invention but not limiting, a limiting mechanism 5 is further included. When the second billboard 22 is in the display position, the limiting mechanism 5 locks the movable frame 2 and the support column 12 to limit the movable frame 2 to remain in the raised position. This prevents the movable frame from falling when the second billboard is not in the folded position, causing a collision. At the same time, it can provide support force to reduce the force on the gear rack and sprocket chain.

[0038] Further, as a preferred embodiment of the present invention but not limiting, the lateral movement mechanism 4 further includes a main track 43, a main slider 44 disposed on the main track 43, and the limiting mechanism 5 includes a connecting rod 51 disposed on the main slider 44, one end of the connecting rod 51 is connected to the second billboard 22, and the other end is used to pass through the movable frame 2 and the support column 12 when the second billboard 22 is in the exhibition position. The main slider can be driven manually or electrically.

[0039] Further, as a preferred implementation of the present solution but not limiting, the frame 1 is provided with a protective member 6, which is arranged corresponding to the storage position. The protective member can be a protective net or tempered glass, and when stored, the first billboard can be seen through the protective member.

[0040] Further, as a preferred implementation of the present solution but not a limitation, the first billboard and the second billboard are display screens.

[0041] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
