Description

Technical Field

[0001] The utility model relates to the technical field of billboards, in particular to an LED billboard with a windproof function. Background Art

[0002] Billboards are a common form of physical advertising. To achieve better publicity effects, billboards generally have a large installation surface to accommodate large-sized advertising screens. This causes them to be subject to great pressure in strong winds, posing a high risk of structural fracture and collapse.

[0003] In order to improve the safety of billboards, it is necessary to set up windproof structures on the billboards. Generally, a certain number of front-to-back vents are opened on the billboards. The vents provide channels for strong winds to pass through to reduce the pressure of strong winds. However, the advertising curtain needs to remove the parts corresponding to the vents. When the removed parts contain important advertising graphics, it will have a greater impact on the publicity effect. To address this type of defect, covering plates that match the vents are often installed on the vents. The front of the covering plate is coated with advertising graphics corresponding to the vent position of the advertising curtain, and the back of the covering plate is connected to an elastic part that pushes the covering plate toward the vent. When strong winds do not appear, the advertising curtain can maintain the integrity of the advertising graphics with the covering plate blocking the vent. When strong winds blow from the front, the covering plate is pushed away from the vent, and the strong wind can pass through the vent, reducing the strong wind pressure and playing a windproof function. However, when strong winds blow from the back, the push plate is firmly pressed on the vent, which still cannot meet the windproof needs. Utility Model Content

[0004] The utility model aims to provide an LED billboard with a windproof function, which has the advantages of good windproof performance, little interference with publicity effects and a wide range of applications.

[0005] The technical solution of the utility model is as follows:

[0006] An LED billboard with a windproof function comprises an outer frame, vertical bars and horizontal bars. The outer frame is rectangular in shape. A plurality of vertical bars are evenly arranged in the left-right direction and a plurality of horizontal bars are evenly arranged in the up-down direction on the square opening surrounded by the outer frame.

DETAILED DESCRIPTION

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example:

[0022] like Figures 1 to 4As shown, this embodiment provides an LED billboard with a windproof function, including an outer frame 1, vertical bars 2 and horizontal bars 3. The outer frame 1 is rectangular in shape. A plurality of vertical bars 2 are evenly arranged on the square opening surrounded by the outer frame 1 in the left and right directions, and a plurality of horizontal bars 3 are evenly arranged in the up and down directions. The vertical bars 2 and the horizontal bars 3 divide the square opening into a plurality of squares 4 of similar shape. A portion of the squares 4 is rotatably connected to a rotating plate 5. The squares 4 connected to the rotating plates 5 are distributed at intervals. A torsion spring shaft 6 is coaxially connected to the rotating connection portion of the rotating plate 5 on the square 4. The torsion spring shaft 6 is in an initial state. In the initial state, the front of the rotating plate 5 connected to it is flush with the front of the outer frame 1, the center line of the rotating plate 5 coincides with the rotation axis of the rotating plate 5, and a locking component 7 for controlling the rotation ability of the rotating plate 5 is provided on the grid 4. An advertising screen 8 is provided on the front of the outer frame 1. The front of part of the rotating plate 5 is connected to the part of the advertising screen 8 that coincides with the position. The part of the advertising screen 8 connected to the rotating plate 5 is separated from the rest of the part. The rotating plate 5 connected to the advertising screen 8 is not stopped from rotating by the locking component 7, and the rotating plate 5 not connected to the advertising screen 8 is stopped from rotating by the locking component 7.

[0023] A rotating plate 5 is rotatably connected to the grid 4, and part of the rotating plate 5 is connected to the part of the advertising curtain 8 that overlaps with the position. When there is no strong wind, the rotating plate 5 stays in the initial position, and the part of the advertising curtain 8 connected to the rotating plate 5 is pieced together with the rest to form a complete advertising image and text, which does not affect the advertising. When there is a strong wind blowing from the front or back, the rotating plate 5 rotates to follow the direction of the strong wind. After the rotating plate 5 is turned away, the strong wind can pass through the grid 4, reducing the thrust of the strong wind on the advertising curtain 8 and reducing the risk of being blown down by the strong wind. The grid 4 is provided with a torsion spring shaft 6 connected to the rotating connection part of the rotating plate 5, so that the rotating plate 5 can automatically return to the initial position after the strong wind disappears. The grids 4 with rotating plates 5 are distributed in multiple places, and the grids 4 with rotating plates 5 are provided with locking components 7 for controlling the rotation ability of the rotating plates 5, so that the staff can connect the non-essential parts of the advertising screen 8 with the rotating plates 5 and rotate with the rotating plates 5, and keep the necessary parts of the advertising screen 8 not connected with the rotating plates 5 and keep the rotating plates 5 fixed in the initial position, thereby improving the windproof ability while ensuring the publicity effect of the advertising screen 8, and can be applicable to various advertising screens 8 printed with different advertising graphics.

[0024] Furthermore, the grid 4 is provided with a plurality of limit blocks 9 on the rear side of the rotating plate 5. When the front side of the rotating plate 5 is flush with the front side of the outer frame 1, the limit blocks 9 abut against the back side of the rotating plate 5. The limit blocks 9 are located on the same side of the left and right sides of the rotation axis of the rotating plate 5.

[0025] The limit block 9 can limit the rotation direction of the rotating plate 5, making it easier for the rotating plate 5 to rotate with the wind. When there is no limit block 9, the rotating plate 5 has the problem of being unable to rotate with the wind because the parts on both sides of the rotating axis are subjected to the same force. After the limit block 9 is provided, when a strong wind blows from the front, the side of the rotating plate 5 that is not abutted from the rear by the limit block 9 is pushed by the wind to rotate backward. When a strong wind blows from the back, the side of the rotating plate 5 that is abutted from the rear by the limit block 9 is pushed by the wind to rotate forward.

[0026] Furthermore, the locking assembly 7 is a locking screw 10, and a threaded hole A11 leading to the rotating connection portion of the rotating plate 5 is provided on the grid 4. The threaded hole A11 is threadedly connected with the locking screw 10, and the locking screw 10 can be rotated to abut the rotating connection portion of the rotating plate 5.

[0027] The rotation ability of the rotating plate 5 is controlled by the locking screw 10. When the rotation ability of the rotating plate 5 needs to be stopped, the locking screw 10 is rotated until it is pressed against the rotation connection part of the rotating plate 5. When the rotation ability of the rotating plate 5 needs to be released, the locking screw 10 is rotated until it is separated from the rotation connection part of the rotating plate 5.

[0028] Furthermore, the outer edge of the advertising screen 8 is connected to the outer frame 1, and the outer frame 1, the vertical rod 2, the horizontal rod 3 and the front of the rotating plate 5 are in contact with the advertising screen 8. The front end of the grid 4 is evenly provided with threaded holes B12 along the outer edge, and the front of the rotating plate 5 is evenly provided with threaded holes B12 along the edge. The threaded holes B12 are threadedly connected to the threaded rods 13. A through hole is opened on the advertising screen 8 for the threaded rods 13 to pass through. A pressure plate 14 is provided on the outer end of the threaded rod 13, and the pressure plate 14 is pressed on the advertising screen 8.

[0029] By using the pressure plate 14, the threaded rod 13 and the threaded hole B12 in combination, the portion cut from the advertising screen 8 is stably connected to the rotating plate 5, and the gap in the advertising screen 8 caused by the cut portion is stably pressed against the edge of the front end of the grid 4, reducing the risk of the advertising screen 8 being torn due to the gap being blown up by strong wind. In addition, the operation of holding the pressure plate 14 to rotate the threaded rod 13 is simple, which makes it convenient for the staff to fix the gap and the cut portion of the advertising screen 8.

[0030] Furthermore, a reinforcing frame 15 is provided on the grid 4 not connected to the rotating plate 5 .

[0031] The reinforcing frame 15 enhances the structural strength of the grid 4 and reduces the risk of deformation.

[0032] The working principle and use process of this utility model:

[0033] The staff installs the advertising screen 8 on the outer frame 1, determines the necessity of each part based on the advertising graphics on the advertising screen 8, connects the non-essential parts to their corresponding rotating plates 5, then cuts off the part of the advertising screen 8 connected to the rotating plates 5 from the advertising screen 8, and uses the locking assembly 7 to stop the rotation of the remaining rotating plates 5 that are not connected to the advertising screen 8. Finally, the outer frame 1 is installed on the corresponding mounting frame or mounting column for advertising.

[0034] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
