DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] Example:

[0024] like Figure 1 - Figure 2 As shown, the present invention provides a technical solution for an advertising light box that is easy to maintain:

[0025] As shown in the figure, an advertising light box which is easy to maintain, its structure includes an advertising light box body 1, a rotating torsion shaft 2 arranged on the upper part of the advertising light box body 1, a movable cover plate 3 connected to the rotating torsion shaft 2 and a support structure 4 for connecting the movable cover plate 3 with the advertising light box body 1, the support structure 4 includes an arc groove 41, side groove bars 42 symmetrically arranged on both sides of the arc groove 41, a limiting groove 43 located inside the side groove bars 42, a spring 44 arranged at the inner end of the arc groove 41, a support rod 45 with one end extending into the arc groove 41 and connected to the spring 44 and the other end connected to the movable cover plate 3, a limiting clamping plate 46 arranged at the end of the support rod 45, a positioning screw hole 47 opened on the surface of the support rod 45, a through hole 48 arranged on the side of the advertising light box body 1 and corresponding to the positioning screw hole 47, and a positioning rod 49 used for positioning the support rod 45 and cooperating with the positioning screw hole 47.

[0026] The support rod 45 is consistent in shape with the arc groove 41 and is movably matched with it in a clearance, which is conducive to the support rod sliding out from the inside of the arc groove and conveniently adjusting the rotation angle of the movable cover.

[0027] There are four positioning screw holes 47 which are evenly and equidistantly spaced. Internal threads are arranged inside the positioning screw holes 47 to facilitate the rotation and fixation of the positioning rod.

[0028] The outer surface of the positioning rod 49 is provided with a rotating pattern that matches the thread pattern provided inside the positioning screw hole 47, which is conducive to fixing the support rod, thereby achieving the fixing of the opening angle of the movable cover and the advertising light box body.

[0029] The number of through holes 48 and the positioning screw holes 47 are the same and they are arranged correspondingly, so that the adjusted support rod can be fixed after the positioning rod passes through the through holes and rotates with the positioning screw holes.

[0030] There are a plurality of limiting grooves 43 which are evenly and equidistantly arranged to achieve locking and positioning with the limiting clamping plate.

[0031] Both ends of the limiting clamping plate 46 are respectively provided with buckling balls that match the limiting grooves 43, which is conducive to clamping and fixing the support rod after adjustment.

[0032] Two supporting structures 4 are provided and are symmetrically arranged on both sides of the advertising light box body 1 and connected to the movable cover plate 3 to support the movable cover plate, making it convenient for maintenance personnel to repair the advertising light box.

[0033] The specific implementation principle is as follows: when the advertising light box body 1 needs to be repaired, the movable cover 3 is lifted up so that it is separated from the advertising light box body 1 with the cooperation of the rotating torsion shaft 2. The support rod 45 is slowly pulled out from the inside of the arc groove 41 under the pulling of the movable cover 3, and the spring 44 is in an extended state. During the pulling process, the limit card 46 is in a limit engagement with the limit groove 43, thereby having a certain resistance to the pulling of the support rod 45. After the movable cover 3 is adjusted to the required position, the positioning rod 49 is extended into the through hole 48 to contact the positioning screw hole 47, and the positioning rod 49 is rotated so that it is rotationally fixedly connected with the positioning screw hole 47 through the internal thread pattern, thereby fixing the support rod 45 to prevent the movable cover 3 from falling off during the work of the maintenance personnel.

[0034] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
