The Moveable signboard of wind direction can be adapted to
[technical field]
The present invention relates to outdoor billboard, particularly relating to one can box haul and turning an angle, to avoid billboard because of the Moveable signboard of the continuous effect and the adapted to wind direction damaged that are subject to front wind-force.
[background technology]
In modern society, advertisement has become the part in people's life, and it appears in face of people with various media and mode, and outdoor advertising is exactly wherein a kind of.Outdoor advertising comprises the advertisement that is arranged on buildings and is erected at road both sides, the such as billboard of highway both sides.Area and the height of roadside poster are much bigger compared with regular price-line advertising board, and existing roadside poster is fixed, and lower end and the ground of its column are fixed, and upper end and the billboard of column are fixed.Because billboard height is higher, often can be subject to the effect of front wind-force, run under the large wind operative condition such as typhoon, the acting force that billboard bears is very large, will inevitably cause the damage of billboard and the increase of maintenance cost through long-term wind-force effect.
[summary of the invention]
The present invention is intended to solve the problem, and provides one can box haul and turning an angle, and to avoid billboard to damage because being subject to the continuous effect of front wind-force, effectively can extend the Moveable signboard of the adapted to wind direction in the serviceable life of billboard.
For achieving the above object, the invention provides a kind of Moveable signboard adapting to wind direction, this Moveable signboard comprises column and billboard main body, it is characterized in that, described column and billboard main body, for being rotationally connected, make billboard main body can turn an angle around column under wind-force effect.
Column is right cylinder, a clutch shaft bearing is respectively equipped with at its upper and lower two ends, is provided with adapter sleeve in billboard lower body part, and it is outside that this adapter sleeve is movably set in described column, and formed with described clutch shaft bearing and be rotationally connected, billboard main body can be rotated around described column.
Column top is inserted in described billboard main body, at the two ends up and down of column insertion portion, a clutch shaft bearing is respectively housed, this clutch shaft bearing is formed with the bearing seat being separately fixed at two ends up and down in described billboard main body and is rotationally connected, and billboard main body can be rotated around described column.
Column is right cylinder, its top is provided with the first pit, second pit corresponding with the first pit on column is provided with at described adapter sleeve inner top, actively steel ball is housed in described first pit and the second pit, in the lower end of column, the second bearing is housed, described adapter sleeve and described steel ball and the second bearing are formed and are rotationally connected, and billboard main body can be rotated around described column.
Column is eccentric setting, and the longitudinal centre line of billboard main body is departed from its position of inserting in described billboard main body.
Clutch shaft bearing is radial thrust bearing, and described second bearing is sliding bearing.
Contribution of the present invention is, it efficiently solves the problem that outdoor billboard is easy to because of stressed windward damage.Billboard and its support post are set to rotation connection structure by the present invention, make billboard when the wind-force effect being subject to front, can box haul and turning an angle, thus billboard can be effectively avoided to damage because being subject to the continuous effect of front wind-force, and effectively can extend the serviceable life of billboard, save maintenance cost.It is simple that the present invention also has structure, the features such as cost is low.

[embodiment]
The following example is further explanation of the present invention, does not constitute any limitation the present invention.
Embodiment 1
Consult Fig. 1, Fig. 2, the Moveable signboard adapting to wind direction of the present invention comprises column 10, billboard main body 20, clutch shaft bearing 31, steel ball 33 and the second bearing 34.
Main points of the present invention are, described column 10 is rotationally connected with billboard main body 20, making billboard main body 20 when being subject to wind-force effect, can turn an angle around column 10 and avoid front wind-engaging.
Particularly, as shown in Figure 1, described column 10 is right cylinder, and its lower end foot bolt is fixed on ground.At the axle rank place at the two ends up and down of column 10, a clutch shaft bearing 31 is respectively housed, 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 radial thrust bearing.Be provided with adapter sleeve 21 in billboard main body 20 bottom, the two ends up and down of adapter sleeve 21 are respectively equipped with annular terrace, and for matching with the outer ring of clutch shaft bearing 31, wherein the diameter of the annular terrace of upper end is greater than the diameter of lower end annular terrace.It is outside that this adapter sleeve 21 is movably set in described column 10, and formed with described clutch shaft bearing 31 and be rotationally connected, and billboard main body 20 can be rotated around described column 10.
Embodiment 2
Basic structure is with embodiment 1, difference is, as shown in Figure 3, Figure 4, the top of described column 10 is inserted in described billboard main body 20, at the two ends up and down of column 10 insertion portion, a clutch shaft bearing 31 is respectively housed, two clutch shaft bearings 31 are contained in two bearing seats 32 respectively, two bearing seats 32 are separately fixed at upper and lower two ends in described billboard main body 20, billboard main body 20 is formed by two bearing seats 32 and two clutch shaft bearings 31 be rotationally connected, thus billboard main body 20 can be rotated around described column 10.As Fig. 3, in the present embodiment, described column 10 is in eccentric setting, and the longitudinal centre line of billboard main body 20 is departed from its position of inserting in described billboard main body 20, makes billboard main body 20 be subject to being easy to stop at the position perpendicular with wind surface after wind-force effect turns an angle.
Embodiment 3
Basic structure is with embodiment 1, and difference is, as shown in Figure 5,
Column 10 is right cylinder, its top is provided with the first pit 11, second pit 211 corresponding with the first pit 11 on column is provided with at described adapter sleeve 21 inner top, in described first pit 11 and the second pit 211, steel ball 33 is housed actively, rotates in the circular hole that this steel ball 33 can surround at the first pit 11 and the second pit 211.Second bearing 34 is housed in the lower end of column 10, and this second bearing 34 is sliding bearing.Described adapter sleeve 21 is formed with described steel ball 33 and the second bearing 34 and is rotationally connected, and billboard main body 20 can be rotated around described column 10.
