Outdoor LED display screen for windy area
Technical field
The utility model relates to a kind of LED display, specifically refers to a kind of outdoor LED display screen for windy area.
Background technology
Outdoor LED display screen for windy area, as the new lover of outdoor demonstration in future advertising media, be widely used in finance, the tax, industry and commerce, post and telecommunications, physical culture, advertisement, industrial enterprise, communications and transportation, educational system, station, harbour, airport, market, hospital, hotel, bank, securities market, construction market, auction room, Industrial Management and other public place.Have display advertising, information issue, traffic guidance, the purposes such as intention demonstration.For the outdoor LED display screen of windy area: area general tens square metres square metre even larger to hundreds of, brightness is high, can work greatly in the sun in visual angle, has certain windproof, rainproof, water-proof function.Be mainly used in outdoor advertising, station, square, market etc.
Outdoor LED display screen for windy area occurs with the form of outdoor media conventionally.Outdoor media refer to key construction roof and sowntown in front of the door, the medium of the information of the releasing advertisements that arranges of the outdoor sports ground such as roadside, principal mode comprises paths of LEDs display screen, LED electronic display, LED full-color screen, LED screen, balloon, dirigible, compartment, large-scale Inflated model etc.
Outdoor LED electrical screen media are the trend of 21 century advertising development, are the indoor outer advertisement display devices with audio frequency and video function, belong to high-tech product leading in the world.Such equipment appearance is novel unique, and its area can arbitrarily be adjusted, can not only playing audio-video advertising programme, and four sides also can fill fixedly lamp box advertisement position, and existing various places government all encourages to carry out using outdoor LED to shield, and cancels successively canvas advertisement, lamp box advertisement is examined.Outdoor LED screen is the desirable substitute products of canvas advertisement, lamp box advertisement.LED electrical screen media are divided into picture and text display media and video display media, by LED matrix-block, form.Picture and text display media can with computing machine simultaneous display Chinese character, English text and figure; Video display media adopts microcomputer to control, picture and text, image luxuriant, with in real time, synchronously, information propagation pattern is play various information clearly, also can show two dimension, three-dimensional animation, video recording, TV, VCD program and on-the-spot circumstance.The display frame of LED electrical screen media is bright in luster, stereoscopic sensation is strong, quiet as oil painting, moving as film, be widely used in finance, the tax, industry and commerce, post and telecommunications, physical culture, advertisement, industrial enterprise, communications and transportation, educational system, station, harbour, airport, market, hospital, hotel, bank, securities market, construction market, auction room, Industrial Management and other public place.
Outdoor LED display screen for windy area of the prior art; do not design special wind resistance protection structure; when running into strong wind; the wind lotus of bearing for the outdoor LED display screen of windy area is very large; although all have the pedestal of steelframe structure or cement framework that wind resistance support is provided for some large-scale screens; but for some little LED display; narrower long strip type LED display is more particularly connected; this class display screen is often used for some information such as demonstration shop trick; it does not have solid windproof wind resistance pedestal, and wind resistance is very poor.In sum, be badly in need of at present a kind of wind resistance better for the outdoor LED display screen for windy area of the strips such as demonstration shop trick.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of wind resistance better for the outdoor LED display screen for windy area of the strips such as demonstration shop trick.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of outdoor LED display screen for windy area, it comprises display screen main body, and described display screen main body is provided with the LED lamp pearl by array distribution, and described display screen main body overcoat has transparent bearing; Display screen main body upper top is provided with weathervane; Described transparent bearing comprises outer ring, inner ring and ball; Ball is arranged between outer ring and inner ring; Inner ring is connected by connecting rod with described display screen main body, described outer ring be provided with two be located along the same line and one towards previous drag reduction tip backwards, described weathervane is connected with outer ring by connecting link, and the sensing of weathervane immobilizes with the sensing relative position identical and between the two of drag reduction tip; The below of described display screen main body is connected with expansion link, and the below of expansion link is provided with pedestal, and the periphery of expansion link is provided with hurricane globe.
Described ball divides two groups, one group of top being located between outer ring and inner ring, and another group is located at the bottom between outer ring and inner ring; Described ball consists of transparent material.
Adopt after said structure, the utlity model has following advantage: described display screen main body overcoat has transparent bearing; Display screen main body upper top is provided with weathervane; Described transparent bearing comprises outer ring, inner ring and ball; Ball is arranged between outer ring and inner ring; Inner ring is connected by connecting rod with described display screen main body, described outer ring be provided with two be located along the same line and one towards previous drag reduction tip backwards, described weathervane is connected with outer ring by connecting link, and the sensing of weathervane immobilizes with the sensing relative position identical and between the two of drag reduction tip.Combination by transparent bearing and weathervane can drive weathervane to rotate by wind, weathervane drives the outer ring of transparent bearing synchronously to rotate again, transparent bearing can drive the drag reduction tip on outer ring to rotate simultaneously, due to drag reduction tip towards with weathervane towards being the same, when so each strong wind comes, weathervane can drive drag reduction head to rotate very fast, makes it aim at the direction that wind comes, and the wind load that display screen main body is subject to is minimum.Bearing arrangement cleverly in addition, display screen main body can't be followed weathervane and be rotated together with outer ring.The below of described display screen main body is connected with expansion link, and the below of expansion link is provided with pedestal, and the periphery of expansion link is provided with hurricane globe.When running into the forecast informations such as strong wind or typhoon, managerial personnel can be on the scene in advance expansion link is contracted downwards, and display screen main body is retracted in hurricane globe together with structures such as transparent bearings, effectively display screen main body are protected.
Also have described ball to divide two groups, one group of top being located between outer ring and inner ring, another group is located at the bottom between outer ring and inner ring; Described ball consists of transparent material.This design has been eliminated ball completely on the impact of display screen main body, can not stop the demonstration of display screen main body.
In sum, the utility model provides a kind of wind resistance better for the outdoor LED display screen for windy area of the strips such as demonstration shop trick.
