Abstract

The utility model is composed of a front billboard and a back billboard that are on the upper part, and a post that supports the billboards. The post and the billboards form an eccentric post. The billboards and the post are connected into a part by a connecting shaft sleeve. The lower end of the connecting shaft sleeve is supported by the rotation rail of the post in a rotary way and the upper part of the connecting shaft sleeve is connected with the billboards. A rotary reset device is fixed on the billboards. A supporting post penetrates into the rotary reset device. The rotary reset device mainly includes reset springs, which are arranged on two sides of the supporting post symmetrically, one end of which is connected with a fixed plate that is connected with the two billboards and another end of which is connected with moveable stressed plates. A rotary slider is fixed on the upper part of the supporting post. The slider is equipped between the moveable pressed plate. Two ends of the rotary slider are cones or pyramids. The billboard effectively avoids problems that excessive force produced on the supporting post makes the supporting post broken. The billboard can reset immediately, removes torque, saves raw materials and lowers raw material cost.

Description

The roadside windproof advertising board

Technical field: the utility model relates to a kind of billboard, relates in particular to a kind of large-scale roadside windproof advertising board that is arranged on highway, bridge both sides.

Background technology: along with development of market economy, it is a kind of very important strategy that enterprise is taked in intense market competition that manufacturer and operator utilize various advertisements to propagate with the influence that enlarges product, the popularity that improves enterprise or product.Particularly along the line at highway, bridge both sides, the large board of all establishing the design of each businessman or producer is to attract the dealing notice of guest to own product of passing by on one's way.This set is a bigger giant billboard above the large board structure in roadside is, giant billboard is by a column fixed support.This roadside poster is simple in structure, make easily, but its deficiency is: because billboard is bigger, thereby its front face area is big, and it is big to be subjected to the wind-force bump, and the moment of torsion of formation is big, particularly when running into the storm wind of big level type, its column is easy to fracture, makes producer or businessman cause very big loss.

Summary of the invention: run into the easily problem of fracture of high wind column for solving large-scale roadside poster, the purpose of this utility model provide a kind of can make the billboard box haul and change advertisement to the position, prevent that column is subjected to the influence of powerful wind and the roadside windproof advertising board that ruptures.

The technical solution of the utility model realizes in the following manner:

A kind of roadside windproof advertising board, it is made up of the tow sides billboard of top, the column of support billboard, wherein, column and billboard form an eccentric column, be connected as a single entity by a connecting bushing between billboard and the column, the connecting bushing lower end is rotated on the rotation track that is supported on column, fixedlys connected with billboard in top; On billboard, be fixedly connected with the rotation resetting means, support column penetrates and rotates in the resetting means, rotate resetting means mainly comprise be arranged on that the support column symmetria bilateralis is arranged, back-moving spring that an end and the fixed head connection that is connected two billboards, the other end are connected with stressed portable plate, be fixed with a turning block on support column top, turning block is clamped between the stressed portable plate, and the turning block two ends are cone.

Establish some groups of back-moving springs between stressed portable plate and the fixed head, establish 1-4 spring between every square metre of movable stressed plate and the fixed head.

Bearing is housed to reduce rotation friction between connecting bushing and column.

The column center is 2/3 of the whole advertisement length of side to billboard distance " L " on one side.

Stressed portable plate by the limiting plate block at two ends in case stressed portable plate deflection.

Rotation track is provided with one makes the billboard rotational angle less than 90 ° limiting block.

Good effect of the present utility model is:

1, effectively prevents the stressed excessive problem that causes the pillar fracture of billboard, because billboard and pillar are movably connected, both can relatively rotate, thereby along with the increase of wind-force, wind speed, billboard rotates around pillar, the windward side of billboard is diminished and reduce wind, reduce moment of torsion, guarantee the pillar safety and stability the billboard impulsive contact force.

2, in time reset, because when billboard rotates with the wind-force increase, the turning block center line is changed to the upright position gradually by the movable stressed plate parallel position with the both sides resetting means, the both sides back-moving spring is compressed, form moment of torsion, in case when wind-force reduces, under the tension force effect of spring, make billboard rotate back into original position again and remove moment of torsion.

3, save the starting material investment, because the rotation resetting means is set, the torsion that bears of column is reduced, the material standard of its column can suitably reduce, and column diameter also can reduce, thereby saves starting material, reduces the starting material investment.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing: by Fig. 1-Fig. 4 as can be seen: this roadside windproof advertising board is made up of positive and negative two billboards 1 of top, the column 8 of support billboard, its column 8 is supported on billboard 1 center one side and forms an eccentric column, and column 8 centers are 2/3 of the whole advertisement length of side to billboard distance " L " on one side; Be connected as a single entity by a connecting bushing 6 between billboard 1 and the column 8, connecting bushing 6 lower ends are rotated on the rotation track 8 that is supported on column, and top and billboard 1 are solid

The fixed connection; By Fig. 3, Fig. 4 as can be seen, mainly comprise two fixed heads 6 that are fixedly connected between two billboards at rotation resetting means fixedly connected between positive and negative two billboards, two stressed portable plates 5 in two fixed heads, between two billboards, between the stressed portable plate 5 of homonymy and fixed head 2, be connected with back-moving spring 3, be fixed with a turning block 4 on support column 7 tops, turning block is clamped between the two movable stressed portable plates 5, and the turning block two ends are cone.

Also can be found out by Fig. 2: between connecting bushing 6 and column 7 bearing 9 is housed, bearing 9 is supported on the slideway of column and rotates along slideway; Stressed portable plate 5 by limiting plate 10 block at two ends in case stressed portable plate deflection.
