Detailed Description
For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings 1-3.
Combine attached figure 1-3, the self-adaptation bill-board of this embodiment, including advertisement frame 1 and bill-board 2, the upper end both sides of bill-board 2 have linked firmly pivot 3 respectively, pivot 3 and 2 integrated into one piece of bill-board, offer the through-hole that is used for installing pivot 3 on the advertisement frame 1, bill-board 2 is rotatable through pivot 3 installs on advertisement frame 1, the end connection of pivot 3 has damping device, damping device exerts the resistance when pivot 3 rotates.
The self-adaptive billboard reduces the rotating speed of the billboard 2 when rotating by applying resistance to the rotating shaft 3 through the arrangement of the damping device when the billboard 2 is turned over under the action of wind power, between two gusts of wind, the billboard 2 can be turned downwards under the action of gravity to reset because of not being influenced by wind force, at the moment, the damping device applies resistance to the rotating shaft 3 to reduce the rotating speed of the billboard 2 when resetting, if the next gust of wind reaches the goal of continuously blowing the billboard 2 to turn upwards in the resetting process, in general, the self-adaptive billboard greatly reduces the rotating speed of the billboard 2 when rotating through the damping device, so that the billboard 2 does not shake violently on the advertisement frame 1 and the turning speed of the billboard 2 is reduced because of the indirect blowing of the wind, the noise generated when the billboard overturns under the action of wind power can be reduced, and the stability of the billboard in windy weather is greatly improved.
As an alternative of the present invention, the damping device is installed in the advertisement frame 1, the damping device includes a damping shaft 41 and a casing 42, the inside of the casing 42 is a hollow structure, the casing 42 is filled with a damping medium, one end of the damping shaft 41 is rotatably disposed in the casing 42, the other end of the damping shaft 41 extends out of the casing 42, the damping shaft 41 is provided with a plurality of damping fins 411 along the circumferential direction thereof, the damping fins 411 are rectangular sheets integrally formed on the surface of the damping shaft 41, the damping fins 411 are located in the casing 42, and the damping shaft 41 is connected with the rotating shaft 3 through a transmission structure; in the process of rotating the rotating shaft 3, the damping shaft 41 rotates together with the rotating shaft 3 under the action of the transmission structure, the damping shaft 41 drives the damping fins 411 to rotate in the shell 42, the shell 42 is filled with damping media, the damping fins 411 generate certain blocking effect on the damping shaft 41 by the resistance between the damping fins 411 and the damping media when rotating, further, the transmission structure generates certain resistance on the rotation of the rotating shaft 3, the rotating speed is reduced when the rotating shaft 3 receives the resistance, the damping device generates the resistance by the damping fins 411 and the damping media, no matter whether the damping fins 411 rotate forwards or backwards in the damping media, the resistance can be increased along with the increase of the rotating speed of the damping fins 411, and therefore the resistance of the damping device on the rotating shaft 3 can be adjusted in a self-adaptive mode according to the size of wind power.
In this embodiment, the damping medium in the housing 42 is viscous oil, the object moves relative to the fluid in the fluid, and the boundary layer on the surface of the object has a velocity gradient and a viscous force, which are expressed as a resistance of the object, and the smaller object slowly moves in the fluid with a larger viscosity, i.e. under the condition of a small reynolds number, the resistance is a main factor, which is called viscous resistance or viscous resistance.
As an alternative of the present invention, the transmission structure includes a first transmission gear 51 and a second transmission gear 52, the first transmission gear 51 is sleeved on the damping shaft 41, the second transmission gear 52 is sleeved on the rotating shaft 3, the first transmission gear 51 and the second transmission gear 52 are engaged for transmission, transmission can be realized between the damping shaft 41 and the rotating shaft 3 through the engagement transmission of the first transmission gear 51 and the second transmission gear 52, and the transmission ratio of the first transmission gear 51 to the second transmission gear 52 is 2: 1; when the second transmission gear 52 rotates under the driving of the rotating shaft 3, the second transmission gear 52 drives the first transmission gear 51 to rotate, since the transmission ratio of the first transmission gear 51 to the second transmission gear 52 is 2:1, the rotating speed of the first transmission gear 51 is greater than that of the second transmission gear 52, which is equivalent to the rotating speed of the damping shaft 41 being greater than that of the rotating shaft 3, the speed of the damping shaft 41 is increased, the resistance on the damping shaft 41 is increased, so that the resistance on the rotating shaft 3 is increased, and the damping device can provide greater resistance for the billboard 2 to reduce the overturning speed of the billboard.
As the utility model discloses an alternative, be equipped with reinforcing ring 421 in the casing 42, reinforcing ring 421 sets up along the circumferencial direction of damping axle 41, damping piece 411's outer end links firmly with reinforcing ring 421, through the setting of reinforcing ring 421 for damping piece 411's outer end is fixed by reinforcing ring 421, and damping piece 411 is difficult for receiving the resistance and takes place deformation, helps improving damping piece 411's structural strength, thereby prolongs its life.
As an alternative of the present invention, the advertisement board 2 includes a rotation portion 21, a first advertisement board 22 and a second advertisement board 23, the rotation portion 21, the first advertisement board 22 and the second advertisement board 23 are integrally formed, the first advertisement board 22 and the second advertisement board 23 are relatively parallel to each other and are disposed below the rotation portion 21, the first advertisement board 22 and the second advertisement board 23 are disposed at intervals, a plurality of first ventilation holes 221 are distributed on the first advertisement board 22, and a second ventilation hole 231 is disposed on the second advertisement board 23 at a position corresponding to a position between two adjacent first ventilation holes 221; wind on one side of the first advertising board 22 can be discharged from the other side of the second advertising board 23 through the first ventilation hole 221 and the second ventilation hole 231, so that an air leakage system is formed between the first advertising board 22 and the second advertising board 23, the advertising board 2 can be kept stable through the air leakage system in breeze weather, the situation that the advertising board swings indefinitely due to breeze is avoided, meanwhile, the advertisement patterns on the inner side of the first advertising board 22 can supplement missing contents at the second ventilation hole 231 of the first advertising board 22 through the second ventilation hole 231, and the advertisement contents on the advertising board are kept complete;
as the utility model discloses an alternative, bill-board 2 is provided with a plurality ofly from top to bottom on advertisement frame 1, the quantity of bill-board 2 can set up to 2, 4, 8 and so on, avoids a monoblock bill-board 2 too huge to lead to the windy weather unable to be blown.
