Abstract

The invention relates to a moveable signboard adaptable to wind direction, comprising a vertical column (10) and a signboard main body (20), wherein the vertical column (10) is rotatably connected with the signboard body (20); the vertical column (10) is a columnar body, wherein the upper end and the lower end of the vertical column (10) are respectively provided with a first bearing (31); a connecting sleeve (21) is arranged at the lower part of the signboard main body (20); the connecting sleeve (20) is moveably sleeved outside the vertical column (10) and rotatably connected with the first bearing (31). The upper part of the vertical column (10) can also be inserted into the signboard main body (20); and the upper end and the lower end of the inserted part of the vertical column (10) are respectively provided with the first bearing (31), respectively. The signboard main body (20) is subjected to rotating by a certain angle around the vertical column (10) under the function of the wind power. The moveable signboard is capable of rotating by a certain angle along with the wind direction so as to prevent the signboard from being broken by continuous function of the front wind power, thereby effectively prolonging the service life of the signboard.

Description

The movable billboard that can adapt to wind direction

[technical field]

The present invention relates to outdoor billboard, but particularly relate to a kind of box haul and turn an angle, to avoid the movable billboard of the adapted to wind direction that billboard damages because of the continuous effect that receives front wind-force.

[background technology]

In modern society, advertisement has become the part in people's life, and it appears at various medium and mode in face of the people, and outdoor advertising is exactly wherein a kind of.Outdoor advertising comprises and is arranged on the advertisement on the buildings and is erected at the road both sides, for example the billboard of highway both sides.The area of roadside poster is much bigger than the regular price-line advertising board with height, and that existing roadside poster is is fixed, and the lower end and the ground of its column are fixed, and the upper end and the billboard of column are fixed.Because the billboard height is higher, regular meeting receives the effect of front wind-force, is running under the large wind effect situation such as typhoon, and the acting force that billboard bears is very big, will inevitably cause the damage of billboard and the increase of maintenance cost through long-term wind action.

[summary of the invention]

The present invention is intended to address the above problem, but and a kind of box haul be provided and turn an angle, damage the movable billboard of adapted to wind direction that can effectively prolong the serviceable life of billboard because of the continuous effect that receives front wind-force to avoid billboard.

For realizing above-mentioned purpose; The present invention provides a kind of movable billboard that adapts to wind direction, and this movable billboard comprises column and billboard main body, it is characterized in that; Said column and billboard main body make the billboard main body under wind action, to turn an angle around column for being rotationally connected.

Column is a right cylinder; It respectively is equipped with a clutch shaft bearing in two ends up and down, is provided with adapter sleeve in the billboard lower body part, and it is outside that this adapter sleeve is movably set in said column; And form with said clutch shaft bearing and to be rotationally connected, make the billboard main body to rotate around said column.

Insert in the said billboard main body on column top; At the two ends up and down of column insertion portion a clutch shaft bearing is housed respectively; This clutch shaft bearing forms with the bearing seat that is separately fixed at the interior two ends up and down of said billboard main body and is rotationally connected, and makes the billboard main body to rotate around said column.

Column is a right cylinder; Its top is provided with first pit; Said adapter sleeve inner top be provided with column on corresponding second pit of first pit, in said first pit and second pit steel ball is housed versatilely, in the lower end of column second bearing is housed; Said adapter sleeve and said steel ball and second bearing form and are rotationally connected, and make the billboard main body to rotate around said column.

Column is eccentric and is provided with, and it inserts the longitudinal centre line of the position deviation billboard main body in the said billboard main body.

Clutch shaft bearing is a radial thrust bearing, and said second bearing is a sliding bearing.

Contribution of the present invention is that it efficiently solves outdoor billboard because of the stressed problem that is easy to damage of facining the wind.The present invention's billboard and its support post are set to rotation connection structure; Make billboard when receiving positive wind action; But box haul and turning an angle; Thereby can effectively avoid billboard to damage because of the continuous effect that receives front wind-force, and can effectively prolong the serviceable life of billboard, save maintenance cost.Characteristics such as the present invention also has simple in structure, and cost is low.

[embodiment]

The following example is to further explanation of the present invention and explanation, and the present invention is not constituted any limitation.

Embodiment 1

Consult Fig. 1, Fig. 2, the movable billboard that adapts to wind direction of the present invention comprises column 10, billboard main body 20, clutch shaft bearing 31, steel ball 33 and second bearing 34.

Main points of the present invention are, said column 10 is rotationally connected with billboard main body 20, makes billboard main body 20 when receiving wind action, can turn an angle and avoid the front wind-engaging around column 10.

Particularly, as shown in Figure 1, said column 10 is a right cylinder, and ground is fixed in foot bolt in its lower end.A clutch shaft bearing 31 respectively is equipped with at place, axle rank at the two ends up and down of column 10, and wherein, the diameter of the endoporus of the clutch shaft bearing of upper end is less than the diameter of bore of the clutch shaft bearing of lower end, in order to assembling.This clutch shaft bearing 31 is a radial thrust bearing.Be provided with adapter sleeve 21 in billboard main body 20 bottoms, the two ends up and down of adapter sleeve 21 are respectively equipped with annular terrace, are used for being complementary with the outer ring of clutch shaft bearing 31, and wherein the diameter of the annular terrace of upper end is greater than the diameter of lower end annular terrace.This adapter sleeve 21 is movably set in said column 10 outsides, and is rotationally connected with said clutch shaft bearing 31 formation, makes billboard main body 20 to rotate around said column 10.

Embodiment 2

Basic structure is with embodiment 1; Different is; Like Fig. 3, shown in Figure 4, insert in the said billboard main body 20 on the top of said column 10, at the two ends up and down of column 10 insertion portions a clutch shaft bearing 31 is housed respectively; Two clutch shaft bearings 31 are contained in respectively in two bearing seats 32; Two ends about two 32 of bearing seats are separately fixed in the said billboard main body 20 make billboard main body 20 form through two bearing seats 32 and two clutch shaft bearings 31 and are rotationally connected, thereby make billboard main body 20 to rotate around said column 10.Like Fig. 3; In the present embodiment; Said column 10 is eccentric and is provided with, and the longitudinal centre line that it inserts the position deviation billboard main body 20 in the said billboard main body 20 makes billboard main body 20 be easy to stop at the position perpendicular with wind surface after wind action turns an angle receiving.
