Detailed Description

The attached drawings are the best embodiments of the automatic rotary outdoor advertisement multi-surface display device, and the invention is further described in detail with reference to the attached drawings.

As shown in the attached drawings 1 to 5, the automatic rotary outdoor advertisement multi-surface display device comprises an arc-shaped display board 1, a rotary drum 2, a central shaft 3, a bottom board 4 and a friction ring 5.

A plurality of arc panels 1 surround 2 axis equipartitions of rotary drum 2 outsides, and 2 covers of rotary drum are established on center pin 3, center pin 3 below and bottom plate 4 fixed connection. In order to watch the content on the arc panel 1 not influenced, the equipartition has 2 ~ 4 arc panels 1 on the rotary drum 2, and this embodiment adopts 3 arc panels 1.

The vertical surfaces of two sides of the arc-shaped display board 1 are provided with clamping strips 101, the circumferential surface of the rotary drum 2 is inwards provided with clamping grooves 201 in a concave mode, and the clamping strips 101 are inserted into the clamping grooves 201.

In order to ensure that the rotary drum 2 cannot move up and down, the upper end of the central shaft 3 is provided with a top limiting cap 301, the lower end of the central shaft is fixed with a bottom limiting column 302, the rotary drum 2 is positioned between the top limiting cap 301 and the bottom limiting column 302, and the bottom surface of the bottom limiting column 302 is fixedly connected with the bottom plate 4. The bottom surface of the top limit cap 301 is in contact with the top surface of the rotary drum 2, the top limit cap 301 is fixedly connected with the central shaft 3 or in threaded connection with the central shaft 3, and if the top limit cap 301 is fixedly connected with the central shaft 3, the top limit cap 301 does not shield the clamping groove 201.

In order to reduce the friction between the rotating drum 2 and the central shaft 3 when rotating, a rotating shaft bearing 6 is arranged between the inner wall of the rotating drum 2 and the central shaft 3.

In order to further reduce the weight of the drum 2, the circumferential surface of the drum 2 is recessed with weight-reducing grooves 202.

2 ~ 6U type poles 203 are evenly distributed to 2 periphery lower extreme equipartitions of rotary drum, all rotate on every U type pole 203 and be connected with a rubber rope 204, rubber rope 204 is located U type pole 203 below. The top of the rubber rope 204 is rotationally connected with the U-shaped rod 203 through a hanging ring, and the lower end of the rubber rope 204 is fixed with a counterweight ball 205. The rubber string 204 may be a rubber rod.

A friction ring 5 is arranged above the bottom plate 4, the friction ring 5 is sleeved outside the central shaft 3 and the rubber rope 204, the friction ring 5 is highly positioned between the U-shaped rod 203 and the counterweight ball 205, and the friction ring 5 is fixedly connected with the bottom plate 4 through a support rod 501.

When the rotary drum 2 rotates, under the action of centrifugal force, the counterweight ball 205 moves towards the direction far away from the central shaft 3, so that an included angle is formed between the rubber rope 204 and the central shaft 3, and the faster the rotary speed of the rotary drum 2 is, the larger the included angle between the rubber rope 204 and the central shaft 3 is. When the rotational speed of rotary drum 2 reached the threshold value,

rubber rope

204 and 5 contacts of friction ring, improve rotary drum 2 pivoted resistance, and then reduce rotary drum 2's rotational speed, avoid the rotary drum 2 rotational speed too high, people watch the content on the arc panel 1 and cause the eye discomfort.

Wind direction changes in four seasons, for example, the northeast wind changes into the southwest wind. At this time, as shown in fig. 6, the clamping bar 101 of the arc display board 1 can be taken out of the clamping groove 201, the arc display board 1 rotates 180 degrees, and the clamping bar 101 on the other side is reinserted into the clamping groove 201, so that the concave surface of the arc display board 1 is always aligned to the wind direction.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge of those skilled in the art.
