The side is fixedly connected with two passive magnets whose magnetic field direction is the vertical direction, the magnetic poles of the two passive magnets are opposite, the two passive magnets cooperate with the two active magnets, and the two passive magnets are respectively arranged directly above or Directly below. The structure of the utility model enables the advertising content on the four sides of the billboard to be viewed at any angle by turning the billboard without moving the angle of view, and after the hand stops turning and the hand is released, the billboard can automatically reset, which is convenient to place and neat beautiful.

Description

Automatic reset billboard

technical field

The invention relates to an automatic reset billboard.

Background technique

There are two kinds of common billboards at present, one is directly fixed by components such as fasteners, and the billboard is fixed and cannot be rotated; the other is that the billboard is fixed on a shaft, and the billboard can be rotated. The first type of fixed billboard, people can only see the advertisement content on one side. To see the other side, people need to go to the other side of the billboard or move the whole billboard + base bracket together, which is inconvenient to see and does not need to be placed Neatly placed; the second type of rotatable billboards, billboards can be rotated independently, but the angle is not fixed, if several billboards together, it will appear messy, not neat and beautiful.

Contents of the invention

In order to overcome the defects of the prior art, the present invention provides the following technical solutions:

A self-resetting billboard, which includes a base and a billboard body that is rotatably connected to the base through a vertical shaft. It is fixedly connected with the base, and there is a horizontal support plate inside the main body of the billboard, and a through hole is set on the support plate, and the upper end of the rotating shaft passes through the above through hole, and the support plates on both sides of the through hole are inlaid with An active magnet whose magnetic field direction is a vertical direction, the magnetic poles of the two active magnets are opposite, and the two sides of the upper part of the rotating shaft are fixedly connected with two passive magnets whose magnetic field direction is a vertical direction, and the magnetic poles of the two passive magnets are opposite. The passive magnet cooperates with the two active magnets, and the two passive magnets are respectively arranged directly above or directly below the two active magnets.

The beneficial effects brought by the present invention are:

1. It is convenient for the display and viewing of billboards. You can see the display content from various angles, which is convenient for placement. No matter from which angle you look at it, the billboards will return to their original positions, and there is no need to reorganize them repeatedly. It is neat and beautiful;

2. It can be extended from the billboard to other applications that need to rotate and automatically reset.

Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

As shown in Figures 1 to 4, a self-resetting billboard includes a base 1 and a billboard body 2 rotatably connected to the base through a vertical rotating shaft 3, the rotating shaft 3 is arranged inside the billboard body 2, The lower end of the billboard main body 2 is inlaid with a bearing 31, and the lower end of the rotating shaft 3 passes through the bearing 31 and is fixedly connected with the base 1. The inside of the billboard main body 2 is provided with a horizontal support plate 4, and the support plate 4 is provided with a through hole. The upper end of the rotating shaft 3 passes through the above-mentioned through hole, and the supporting plates 4 on both sides of the through hole are respectively inlaid with an active magnet 5 whose magnetic field direction is a vertical direction, and the magnetic poles of the two active magnets 5 are opposite. The side is fixedly connected with two passive magnets 6 whose magnetic field direction is the vertical direction. The magnetic poles of the two passive magnets 6 are opposite. The two passive magnets 6 are matched with the two active magnets 5. directly above or directly below the active magnet 5. Turning the main body 2 of the billboard, due to the effect of the magnetic field force of the magnet, like poles repel and opposite poles attract each other. No matter the billboard is at any angle, it can always return to the initial position when the force is stopped.

The advantages of the embodiments of the present invention are: the advertisement content on the four sides of the billboard can be viewed from any angle by rotating the billboard without moving the angle of view, and the billboard can be automatically reset after the hand stops turning and the hand is released. Easy to place, neat and beautiful.

The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto, and any person skilled in the art may make changes or modifications without creative work within the technical scope disclosed in the present invention. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope defined in the claims.
