Abstract

A wind resistance billboard relates to the billboard outdoors and at the high-level buildings. A gear wheel 3 of a fan shaft is connected to a movable slide wheel 6 through a speed transforming gear 4, and one end of the steel wire rope 7 is fixed at the movable slide wheel, while another end thereof is connected with a rotary wheel 17 through passing a guide wheel 9. The rotary wheel is fixed at the lower end of the central shaft 13 of the inner exhibition board 10 of the frame 11, and a spring 19 is fixed at the rotary wheel along the central shaft 13. When meeting the fierce wind, the fan rotates to drive the rotary wheel through the transmission mechanism to make the exhibition board rotate and reduce the wind facing surface. When without wind, the spring can make the rotary wheel return to the former position. Because the utility model uses the machinery rotation without power, the utility model takes advantages of low fault efficiency with saving energy, and can protect the billboard from being damaged by adjusting the wind force according to the wind facing surface.

Description

The wind resistance billboard

One, technical field:

The utility model belongs to the Advertisement label on outdoor and the high-rise.

Two, prospect technology:

Existing outdoor billboard mostly use wooden or steel design as framework, the panel that the surface is fixed with is wooden, dry goods, plastics or glass are made, on paint the displaying content.Such billboard stock size is bigger, so wind surface is also bigger under its upright state, is usually scratched, blows down by strong wind, or fall down from high-rise, easily personal safety is constituted a threat to.Stability and the soundness of people in order to strengthen billboard prevents that strong wind from producing destruction to it, just uses the timber or the steel of excess when preparing advertising board, thereby the cost of the board of preparing advertising is increased, bulky, heavy, simultaneously, also increased the installation difficulty of billboard.

Three, summary of the invention:

The utility model is opened along with the size of wind-force automatically with the panel on the billboard or closed, minimizings wind area is a purpose, protects billboard not to be damaged.The utility model mainly is made up of mechanical driving part and billboard panel two parts.In mechanical driving part, gear on the fan shaft, by a speed gear, driving-belt, connect travelling block, wire rope one end is fixed on the travelling block, and the other end passes angle sheave and is connected with rotor wheel, and the transhipment wheel is fixed in the lower end of panel central shaft in the framework, spring is fixed on the wheel around central shaft, is used for making panel to reset.Be fixed on the rotor wheel of central shaft lower end, link to each other with wire rope by stay cord, the stop pin is fixed on the central shaft on the rotor wheel.In billboard panel part: panel by the bearing fixing on its central shaft two ends on framework, built-in fluorescent tube, illuminating line is penetrated by central shaft, the quantity of panel is one or more, adjacent bond face between the panel and between panel and the framework is that the scarf central shaft that coincide each other connects, and is independent of each other when rotating.When strong wind was arranged, fan rotated, and drove mechanical transmission mechanism, the pulling wire rope, and rotor wheel rotates, and panel is rotated around central shaft, reduces wind surface, by springs return, returns original state when calm.The utility model need not electric power owing to adopt mechanical drive, has characteristics such as failure rate is low, the saving energy, can adjust the wind area of panel at any time according to the wind-force size, and the protection billboard is not destroyed.

Four, description of drawings:

Accompanying drawing is one-piece construction synoptic diagram (partial cutaway).

Five, embodiment:

As shown in FIG., in support 1, be fixed with a fan 2, gear 3 on the fan shaft drives travelling block 6 by a speed gear 4 by driving-belt 5, is connected with a wire rope 7 on the travelling block, by angle sheave 9 fixing on the support 8, the bottom of the framework 11 of wire rope 7 guide securement Graphic Panels 10.Framework 11 is a steel construction, is fixed with five panels 10 above, and each panel is supported by steel skeleton 12.In the centre of panel, all be installed with a steel central shaft 13, the two ends of central shaft are fixed with bearing 14, and the bearing fixing at two ends is on framework 11, and panel 10 can be rotated around central shaft 13.Be independent of each other when rotating for making, between the panel and the adjacent surface between panel and the framework be scarf.The outside surface of the panel 10 that central shaft connects is a glass, on the skeleton 12 of portion, is fixed with four fluorescent tubes 15 within it, and the illuminating line 16 that fluorescent tube is used is introduced by central shaft 13, draws in the perforate in the middle of the central shaft, is connected on the fluorescent tube.At each central shaft 13 bottom, outside the framework 11, all be fixed with rotor wheel 17.On rotor wheel 17, be fixed with a stay cord 18, stay cord 18 all is connected with wire rope 7, and the rotor wheel of distal-most end is then directly fixedlyed connected with the termination of wire rope.Around central shaft 13, be fixed with a back-moving spring 19 above the rotor wheel, when wire rope pulling rotor wheel rotated, 19 on spring was screwed, and when wire rope did not have pulling force, spring then opened, and drove rotor wheel and resetted.Be welded with a stop pin 20 on the central shaft on the rotor wheel 17, the termination of stop pin is fixed with a magnet, when rotor wheel rotation 90 is spent, top stop pin is fixed on the scotch 21 that rotates on the roller box 22 and blocks, can prevent that rotor wheel from driving the panel rotation excessively, because of panel when forwarding windward side 90 to and spend, it is subjected to wind-force face minimum.Whole rotor wheel is rotated roller box and covers, and can prevent from that it from drenching with rain to get rusty.

When strong wind was arranged, fan rotated, and by speed gear, travelling block, pulling wire rope, rotor wheel are subjected to begin to rotate behind the pulling force, and panel just begins to rotate around central shaft, is stopped behind rotation 90 degree; When calm, the spring on the rotor wheel opens, and panel goes back to original position, and the magnet on the stop pin can guarantee that panel resets tightly.
