Technical Field

[0001] The invention relates to the field of light boxes, and in particular to an outdoor publicity advertising light box. Background Art

[0002] Outdoor advertising light boxes occupy an important position in today's advertising field due to their unique structure, remarkable features and wide range of applicable scenarios. They can not only effectively convey information and expand influence, but also add beautiful scenery to the city. By coordinating with lights or patterns, they can attract attention, effectively publicize the content of the advertising panel on the light box, and enhance brand influence.

[0003] The structure of an outdoor light box is usually composed of a supporting frame made of metal or injection molding and a translucent advertising panel. The supporting frame is strong and can well withstand strong winds outdoors. However, the advertising panel must also be translucent and is therefore relatively thin. It is easily damaged and broken under strong winds, resulting in the internal structure of the light box (such as the light source, electrical box) being exposed, which increases the failure rate. The purpose of the present invention is to propose an outdoor light box with good protection against strong winds to solve the above technical problems. Summary of the invention

[0004] The purpose of the present invention is to provide an outdoor advertising light box to solve the problems mentioned in the background technology.

[0006] In order to optimize the above technical scheme, further measures are taken as follows: the limit device includes a limit rod, a limit groove, a receiving panel and a spring. An opening is provided on the second mounting plate. The middle part of the limit rod is located in the opening and is hinged to the second mounting plate. The limit rod can rotate in the horizontal direction. The limit groove is horizontally opened on the side of the light box body. One end of the limit rod is against the limit groove. The receiving panel is arranged at the end of the limit rod. The receiving panel and the limit groove are perpendicular to each other in length direction. The springs are symmetrically arranged on both sides of the limit rod. One end of the spring is connected to the second mounting plate and the other end is connected to the limit rod.

[0007] As a further improvement to the above technical solution: a ball is embedded in the contact end of the limit rod and the limit groove, and the ball can convert sliding friction into rolling friction, reduce the friction between the limit rod and the limit groove, and ensure smooth travel of the limit rod in the limit groove.

[0008] As a further improvement of the technical solution: the protective device includes a track, a protective plate and a rubber band. The track is arranged in pairs and is respectively located at the top and bottom of the first mounting plate and the second mounting plate. The longitudinal section of the protective plate is in the shape of a], and the two ends of the protective plate are against the track to form a moving pair in the vertical direction. The shape of the protective plate matches the front and rear surfaces of the light box body and can cover the advertising panel. The rubber band is arranged along the length direction of the protective plate, and the rubber band connects the track and the protective plate.

[0009] As an improvement to the above technical solution: an anti-drop block is formed at the end of the track, and the length direction of the anti-drop block is perpendicular to the length direction of the track. By setting the anti-drop block, the protective plate can be prevented from falling off the track, ensuring that the protective plate can protect the light box body.

[0010] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages:

[0011] The present invention provides an outdoor publicity advertising light box, which feeds back wind force through a protective device, and can cover the advertising panels on the front and rear sides of the light box body after being triggered, thereby protecting the advertising panels and preventing the advertising panels from being damaged by wind force. At the same time, the orientation of the advertising panels can be changed from front-to-back orientation to up-and-down orientation during the process, thereby preventing the advertising panels from direct contact with wind force, helping to reduce the damage rate of the advertising panels, and having practical significance and promotion value.
