Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to an arc-shaped LED display screen capable of double-sided display. Background Art

[0002] Double-sided display screens are widely used on the roofs of taxis to display various information. Because they are double-sided, they can display more comprehensive information. However, in actual use, we found that the existing double-sided display screens still have the following disadvantages when used:

[0003] 1. Existing double-sided display screens all use straight screens. Under the same width of space, the straight screen displays relatively less information;

[0004] 2. The existing double-sided display screen is not provided with a protective structure. When encountering some bad weather or when not used for a long time, the display screen is easily damaged by external factors. Utility Model Content

[0008] A double-sided display mechanism, the double-sided display mechanism includes a mounting seat fixedly connected to the upper end of a mounting plate, and arc-shaped display screens are installed on the front and rear sides of the mounting seat; a limiting mechanism, the limiting mechanism includes two connecting boxes symmetrically fixedly connected to the upper end of the mounting plate, and strip-shaped openings are provided on opposite sides of the two connecting boxes, and slides that can slide left and right are provided in the two connecting boxes, and the opposite sides of the two slides are elastically connected to the inner walls of the corresponding connecting boxes through springs, and wedge blocks are fixedly connected to the opposite sides of the two slides, and the other side of each wedge block passes through the strip-shaped opening, and limiting grooves are provided on the left and right sides of the connecting box.

[0009] Preferably, the inclined surfaces of the two wedge-shaped blocks are both facing upwards.

[0010] Preferably, opposite sides of the two slide plates are fixedly connected with pull rods, and the other ends of the two pull rods penetrate the inner wall of the corresponding connection box and extend to the outside.

[0011] Preferably, opposite sides of the two slide plates are fixedly connected with pull rods, and the other ends of the two pull rods penetrate the inner wall of the corresponding connection box and extend to the outside.

[0012] Preferably, a plurality of guide posts are fixedly connected to the upper end of the mounting plate, a guide opening is provided at the lower end of the cover body, and the plurality of guide posts are matched with the plurality of guide openings.

[0013] Preferably, both of the two arc-shaped display screens are LED display screens.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By using a double-sided display mechanism and cooperating with the curved structure of the display screen, more information can be displayed within a limited width. When the display part needs to be protected, it is only necessary to first align the multiple guide openings on the cover body with the multiple guide columns, and then press the cover body downward. The cover body can be used for protection. When disassembly is required later, only one person needs to pull the two pull rods away from each other, and after the wedge block leaves the limit groove, the cover body can be removed. The disassembly and assembly of the protective part is also relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 4 , a double-sided curved LED display screen, comprising a mounting plate 1 and a cover 5;

[0023] The double-sided display mechanism includes a mounting base 8 fixedly connected to the upper end of the mounting plate 1, and arc-shaped display screens 2 are installed on the front and rear sides of the mounting base 8. Both arc-shaped display screens 2 are LED display screens. By using the double-sided display mechanism and the arc surface structure of the display screen, more information can be displayed within a limited width. The LED screen is a new type of imaging electronic device made of light-emitting diodes arranged in sequence. Due to its high brightness, wide viewing angle, long life and other characteristics, it is widely used in outdoor advertising screens and other products.

[0024] Wherein, it also includes a limiting mechanism, which includes two connection boxes 3 symmetrically fixedly connected to the upper end of the mounting plate 1, and strip-shaped openings 9 are provided on opposite sides of the two connection boxes 3. Slide plates 11 that can slide left and right are provided in the two connection boxes 3, and the opposite sides of the two slide plates 11 are elastically connected to the inner wall of the corresponding connection box 3 through springs 14. Wedge blocks 10 are fixedly connected to the opposite sides of the two slide plates 11, and the inclined surfaces of the two wedge blocks 10 are facing upward. The other side of each wedge block 10 passes through the strip-shaped opening 9, and limiting grooves 6 are provided on the left and right sides of the connection box 3. Pull rods 7 are fixedly connected to the opposite sides of the two slide plates 11, and the other ends of the two pull rods 7 pass through the inner wall of the corresponding connection box 3 and extend to the outside, and each pull rod 7 is penetrated by an opening 13;

[0025] The upper end of the mounting plate 1 is fixedly connected with a plurality of guide posts 4 , and the lower end of the cover body 5 is provided with a guide opening 12 , and the plurality of guide posts 4 are matched with the plurality of guide openings 12 .

[0026] In the present invention, when used, the double-sided display mechanism is used in combination with the curved surface structure of the display screen to display more information within a limited width.

[0027] When the display part needs to be protected, it is only necessary to align the multiple guide openings 12 on the cover body 5 with the multiple guide columns 4, and then press the cover body 5 downward. The lower end part of the cover body 5 will first push against the two wedge blocks 10, and use the slide plate 11 to compress the corresponding spring 14. When the lower end of the cover body 5 contacts the upper end surface of the mounting plate 1, the lower end surface of the wedge block 10 is just flush with the inner bottom surface of the limiting groove 6. At this time, under the elastic action of the spring 14, the two wedge blocks 10 will be inserted into the limiting groove 6 to complete the limiting. The cover body 5 can be used for protection. When disassembly is required later, only one person needs to pull the two pull rods 7 to move in opposite directions. After the wedge block 10 leaves the limiting groove 6, the cover body 5 can be removed.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
