technical field

The utility model relates to the field of advertising devices, in particular to a rotatable advertising board.

Background technique

When people walk on the street, whether in a bustling metropolis or in a remote small town, they can see advertisements. When people turn on the TV and radio, they can often see and hear various advertisements; When you open newspapers and magazines, take a car, or go to the mall, you can feel that advertisements abound. Advertising has penetrated into all aspects of people's clothing, food, housing, and transportation. It is like an invisible bond that connects enterprises, businesses and consumers around the world. domain plays an important role. There are various forms of advertising, among which the use of billboards for advertising display is an economical and effective way of advertising. Traditional billboards are mostly fixed and cannot be rotated. Basically, they use single-sided advertising display, and the utilization efficiency of billboards is not high. High, if a multi-faceted advertisement is used, the billboard with a fixed structure cannot switch the viewing angle.

Utility model content

The utility model provides a rotatable billboard. The rotatable billboard can display advertisements on four sides at the same time, and can realize intermittent rotation. The billboard can be switched automatically and intermittently, avoiding the problem of blocking the viewing angle and improving the efficiency of advertisement publicity. .

In order to achieve the above purpose, the utility model provides the following technical solutions: a rotatable billboard, including a fixed base, a box assembly, an intermittent rotation mechanism and a billboard assembly, the middle part of the fixed base is provided with a bearing, and the box The body assembly is fixedly installed on a fixed base. The intermittent rotation mechanism is composed of a motor and a rotating shaft. The motor is fixedly installed on a fixed base. The output shaft end of the motor is fixed with an incomplete bevel gear. The incomplete The bevel gear is provided with a tooth sector, the rotating shaft is rotatably connected with the bearing, and is rotatably connected with the box assembly, and the driven bevel gear is fixed on the rotating shaft, and the driven bevel gear meshes with the tooth sector, and the The billboard assembly is threaded on the axis of rotation.

Preferably, the box assembly includes a motor box and a gear box, both of which are fixedly mounted on a fixed base, and the motor box is fixedly mounted on a side end of the gear box.

Preferably, the upper end of the gearbox is provided with a guide sleeve column, and the rotating shaft is rotatably connected to the guide sleeve column.

Preferably, the tooth sector is 90°.

Preferably, a limiting tray is arranged on the rotating shaft.

Preferably, the billboard assembly includes a cross mounting frame and a billboard. There are four billboards, and the four billboards are welded in sequence to form a square structure. Each side of the cross mounting frame is welded to the middle of the back end of the billboard respectively. , and is threadedly connected with the rotating shaft, and is tightly connected by screws, and the bottom end of the cross mounting bracket is in contact with the limit tray.

The beneficial effects of adopting the above technical scheme are: the structure of the utility model is a rotatable billboard, and the device is provided with four billboards, that is, the four billboards constitute a four-sided structure, and the four billboards can post different advertisements , the motor is connected to an external power supply circuit. The rotatable billboard can mainly realize intermittent rotation. Specifically, if the incomplete bevel gear is a complete bevel gear, it is exactly the same as the driven bevel gear. The motor rotates, Realize the incomplete bevel gear rotation, the incomplete bevel gear and the driven bevel gear mesh only when the tooth sector is in position, the tooth sector is only a quarter turn, and the driven bevel gear will be driven to rotate during the meshing process of the tooth sector, that is to say, The rotation of the rotating shaft realizes the rotation of the billboard assembly. When the gear fan rotates, it just drives the rotating shaft to rotate a quarter of a turn, and it just makes one of the billboards rotate 90 degrees, that is, it has been switched under the same viewing angle. For a billboard, when the incomplete bevel gear rotates at the position of three-quarters of the non-toothed sector, the billboard remains still. By reducing the speed of the motor, the dwelling time of each billboard can be increased. In summary , the rotatable billboard can display advertisements on four sides at the same time, can realize intermittent rotation, and automatically and intermittently realize the switching of the billboard, avoiding the problem of blocking the viewing angle and improving the efficiency of advertising.

Detailed ways

Next, with reference to the accompanying drawings, through the description of the embodiments, the specific implementation of the present utility model will be further described in detail, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present utility model , and contribute to its implementation.

Figures 1 to 3 show a specific embodiment of the present invention: a rotatable billboard, including a fixed base 1, a box assembly 2, an intermittent rotation mechanism 3 and a billboard assembly 4, and the middle part of the fixed base 1 is provided with Bearing 11, the box assembly 2 is fixedly mounted on the fixed base 1, the intermittent rotation mechanism 3 is composed of a motor 31 and a rotating shaft 32, the motor 31 is fixedly mounted on the fixed base 1, the output of the motor 31 The shaft end is fixed with an incomplete bevel gear 31-1, the incomplete bevel gear 31-1 is provided with a gear sector 31-11, the rotating shaft 32 is rotatably connected with the bearing 11, and is rotatably connected with the box assembly 2, The rotating shaft 32 is fixed with a driven bevel gear 32 - 1 , the driven bevel gear 32 - 1 meshes with the gear sector 31 - 11 , and the billboard assembly 4 is screwed on the rotating shaft 32 .

In this embodiment, the box assembly 2 includes a motor box 21 and a gear box 22, both of which are fixedly mounted on the fixed base 1, and the motor box 21 is fixedly mounted on the side of the gear box 22 At the end, the box assembly 2 provides structural protection.

In this embodiment, the upper end of the gear box 22 is provided with a guide sleeve post 22-1, and the rotating shaft 32 is rotationally connected with the guide sleeve post 22-1, and the guide post sleeve 22-1 can enhance structural strength and stability.

Principle of the utility model and working process thereof:

Based on the above, the structure of the utility model is a rotatable billboard, and the device is provided with four billboards, that is, four billboards 42 constitute a four-sided structure, and the four billboards 42 can post different advertisements, and the motor 31 is When connected to an external power supply circuit, the rotatable billboard can mainly realize intermittent rotation. Specifically, if the incomplete bevel gear 31-1 is a complete bevel gear, it is exactly the same as the driven bevel gear 32-1. The motor 31 rotates to realize the rotation of the incomplete bevel gear 31-1. The incomplete bevel gear 31-1 and the driven bevel gear 32-1 are only meshed at the position of the tooth sector 31-11, and the tooth sector 31-11 is only 1/4 One turn, during the meshing process of the toothed sector 31-11, the driven bevel gear 32-1 will be driven to rotate, that is, the rotation of the rotating shaft 32 will be realized, thereby realizing the rotation of the billboard assembly 4. When the toothed sector 31-11 rotates, just Driving the rotating shaft 32 to rotate a quarter of a circle also just makes one of the billboards 42 rotate 90 degrees, that is, a billboard 42 has been switched under the same viewing angle, and the incomplete bevel gear 31-1 is in the three-quarters non-rotating position. During the rotation of the gear sector 31-11 position, the billboard 42 remains motionless all the time, and the time for each billboard 42 to stay can be increased by reducing the rotating speed of the motor 31. In summary, the rotatable billboard can simultaneously Displaying four-sided advertisements can realize intermittent rotation, and automatically and intermittently switch billboards 42, avoiding the problem of viewing angle occlusion, and improving the efficiency of advertising.

The utility model has been exemplarily described above in conjunction with the accompanying drawings.
