Abstract

The utility model relates to an outdoor advertising device, more specifically, the utility model discloses an automatic resistance reducing advertising board. The utility model is composed of a big frame and a panel, which is characterized in that a support frame in a shape like the Chinese character 'jing' is arranged in the big frame to form a plurality of small frames with definite sizes, and a movable acanthus is connected to the inner side of each of the small frames through a shaft. The movable acanthus can be embedded in the support frame, and the panel is formed from the front part of the movable acanthus, the back part of the movable acanthus and the support frame which are in parallel. The lower end of the movable acanthus can turn breadthwise, advertisements can be directly drawn on the panel, or an advertisement picture which can be decomposd can be respectively attached on the support frame and the movable acanthus to form a whole picture through split joint. The utility model which discloses a resistance reducing advertising board has the advantages of simple structure, easy manufacturing and safe use.

Description

A kind of automatic drag reduction billboard

Technical field

The utility model relates to a kind of outdoor advertising device, exactly is a kind of billboard of automatic drag reduction.

Background technology

In modern society, advertisement has been a kind of important means of market competition, people will contact many advertisements every day, every gram is many when per is transmitting various information to people, yet, in nearest several years, we often hear the news that billboard is blown off and hurts sb.'s feelings by strong wind, the large-scale advertisement of establishing in the top and the highway both sides in building particularly, and its windward side has tens square metres, particularly will be subjected to tens tons pressure in the typhoon at strong wind, be easy to billboard be blown down or blow off, the security of billboard has become the hot issue that the public extremely pays close attention to, at present, in order to solve the safety problem of billboard, the way of reinforcing, the billboard of highway both sides, nearly 100 centimeters of its column diameters of adopting more, billboard also adopts very thick steel plate, waste material increases cost, does not also fundamentally solve safety problem, therefore, the security that how to strengthen large board is the major issue that advertising circle presses for solution.

Summary of the invention

The purpose of this utility model provides a kind of billboard, fundamentally solves the safety issue of billboard in strong wind, requires to have simple in structure, handling ease, advantage safe in utilization.

Goal of the invention of the present utility model is achieved by following technical proposals.

A kind of automatic drag reduction billboard, form by big frame and panel, it is characterized in that in big frame, being provided with the bracing frame of groined type, form some a certain size small frames, all pass through one in each small frame and connect an active leave board, active leave board embeds bracing frame, concordant formation panel with bracing frame, formation can be rotated in front and back in the lower end of active leave board, and advertisement can directly be drawn on the panel, be attached to respectively on bracing frame and the active leave board after perhaps advertisement poster being decomposed, be spliced to form whole picture.Also can a spring be set between active leave board and the bracing frame with the resistance of increase active leave board rotation and the restoring force after the rotation.

Adopted rotating active leave board in the utility model, when wind-force reaches certain degree, the lower end of impeller begins to rotate with the wind, form one ventilative mouthful, automatically reduced wind surface, just reduced the pressure that whole billboard is subjected to, wind-force is big more, and the angle of rotation is big more, ventilative mouthful of forming is big more, the pressure that whole billboard is subjected to remains unchanged substantially, realizes the effect of automatic drag reduction, has improved the security of billboard, one spring is set between active leave board and bracing frame can increases the resistance that active leave board rotates, hour maintenance is motionless at wind-force, increases restoring force after rotation, makes billboard recover former state rapidly.Owing to be large-scale outdoor advertising, when not having wind or gentle breeze, billboard and other billboards have no difference, when medium wind-force, active leave board rotates and has opened a less angle, the panel injustice, but far seeing can be too unobvious, does not influence advertising results, and because the swing of active leave board forms some variations of panel, be more prone to attract passerby's sight line, advertising results are better, having strong wind or typhoon to come temporarily, because active leave board has opened a bigger angle, destroyed globality, but at this moment basic nobody can remove to note billboard, also can not influence result of use, adopts the method for small panel splicing, processing is more prone to, and, can correspondingly reduce the size of the bracing frame or the column of billboard because the stressed of billboard reduced, reduced cost, therefore, a kind of drag reduction billboard of the utility model has simple in structure, handling ease, advantage safe in utilization.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the spring structure synoptic diagram.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Adopt the square steel pipe welding of 5CM*5CM to form a high 3200CM, the framework 1 of wide 9500CM, the centre adds a strut rail and erects shelves as bracing frame 2 every 100CM, form the small frame 5 of 27 100CM*100CM, again with 5MM thick steel plate or 27 small panel 4 of aluminium sheet processing, four limits of small panel are rolled over backward and are made and just can put into small frame, an axis hole is opened in upper end on the both sides of rolling over backward, on the relevant position of small frame, also open two axis holes, with one 3 small panel is connected on the small frame, form active leave board, on axle, put two springs 6 as shown in Figure 2, one end 7 of spring is fixed on the small frame, the other end 8 is fixed on the small panel, make that the front of small panel is concordant with the front of small frame, when not having wind, keep the front to form a complete plane, draw advertisement in the plane, again whole billboard is fixed on the support, the large board that can resist typhoon has just been made, at wind-force hour, active leave board can not rotate, situation as A window among Fig. 1, at this moment be a complete billboard, advertising results are unaffected, when wind-force reaches certain degree, the lower end of impeller begins to rotate with the wind, situation as B window among Fig. 1, form one ventilative mouthful, automatically reduced wind surface, just reduced the pressure that whole billboard is subjected to, wind-force is big more, the angle of rotating is big more, ventilative mouthful of forming is big more, as C among Fig. 1, the situation of D window, the pressure that whole billboard is subjected to remains unchanged substantially, realize the effect of automatic drag reduction, improved the security of billboard, a spring is set between active leave board and bracing frame can increase the resistance that active leave board rotates, and hour maintenance is motionless at wind-force, after rotation, increase restoring force, make billboard recover former state rapidly.Owing to be large-scale outdoor advertising, when not having wind or gentle breeze, billboard and other billboards have no difference, when wind is arranged, active leave board rotates gradually and has opened an angle, the panel injustice, as long as billboard is firm when not having wind, big again wind can not blow down it yet, and this is the billboard of an overall safety.
