Problems solved by technology
[0002] In traditional outdoor billboards, there is no protective device for the screen. In rainy days and windy days, it is easy to accelerate the oxidation of the screen due to rain, and objects blown by the wind may hit the screen and cause damage. Therefore, it is necessary to design a Outdoor billboards that can be raised and lowered and have rain protection function to solve the above problems

Embodiment Construction
[0018] Combine below Figure 1-5 The present invention is described in detail, wherein, for the convenience of description, the orientations mentioned below are now defined as follows: figure 1 The projection relationship of itself is the same as the up, down, left, right, front, and rear directions.
[0019] The lower support column 10 described in conjunction with FIGS. 1-5 is provided with a first rotation cavity 74 inside the lower support column 10 , and a first rotation shaft 11 is arranged inside the first rotation cavity 74 . A pin 13 is fixed on the left wall of the rotating cavity 74, and the pin 13 is slidably connected to the first rotating shaft 11. The left side of the first rotating cavity 74 is provided with a positioning rod 12 extending upward. The positioning rod 12 Slidingly connected with the lower support column 10 , a second rotating shaft 20 extending upward is fixed above the first rotating shaft 11 , a main box 24 is arranged above the lower supporti...

The invention relates to the field of advertising boards, in particular to a liftable outdoor advertising board with a rain shielding function. The liftable outdoor advertising board with the rain shielding function comprises a lower supporting column; a first rotating cavity is formed in the lower supporting column; a first rotating shaft is arranged in the first rotating cavity; a pin is fixedlyarranged on the left wall surface of the first rotating cavity; and the pin is connected with the first rotating shaft in a sliding manner. The advertising board is simple in structure, the functionsof protecting an advertising screen in rainy days and removing dust can be achieved, a shielding plate can be automatically lowered in the rainy days, the screen is prevented from making contact withwater, the screen is prevented from being contaminated by rainwater to cause rapid oxidation of the surface of the screen, meanwhile, the advertising board can be lifted, and the visual range of theadvertising board is widened.
Description
technical field [0001] The invention relates to the field of billboards, in particular to an outdoor billboard that can be lifted up and down and has a rain-proof function. Background technique [0002] In traditional outdoor billboards, there is no protection device for the screen. In rainy days and windy days, it is easy to accelerate the oxidation of the screen due to the rain, and the objects blown by the wind from the outside may hit the screen and cause it to be damaged. Therefore, it is necessary to design a kind of Outdoor billboards that can be raised and lowered and have a rain-proof function can solve the above problems. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an outdoor billboard that can be raised and lowered and has a rain-blocking function, which can overcome the above-mentioned defects of the prior art, thereby improving the practicability of the device. [0004] The technical solution adopted by the present inv...
