Abstract

The utility model discloses a wind-destroy resistant advertisement frame and aims at providing a new technical scheme which can lead the length direction of an advertisement board to tend to the wind direction when a devastating wind is blowing, thus avoiding destroy. The wind-destroy resistant advertisement frame comprises an upright post, a sleeve, a spring, an upper ball slot and a lower ball slot, steel balls, an advertisement frame, and the like. The annular lower ball slot the upper side of which is concave to the lower side is fixedly connected on the round upright post; the steel balls are uniformly arranged in the ball slot; the upper ball slot of the same shape the concave surface of which faces to the lower side is arranged on the steel balls; the upper ball slot is not fixedly connected with the wall of the upright post; the lower side opening of one cylindrical matter, namely the sleeve the inner diameter of which is a little larger than the outer diameter of the upright post is fixedly connected with the upper surface of the upper ball slot; the top end of the upright post is provided with a bolt; the lower end of a compression spring the inner diameter of which is larger than the outer diameter of the sleeve extends into a lower clamping hole below the lower ball slot on the wall of the upright pos and the upper end extends an upper clamping hole above the upper ball slot at the lower end of the sleeve; the square advertisement board is then fixedly connected with the sleeve; simultaneously the vertical central line of the advertisement board is arranged to deviate from the axis of the upright post a little.

Description

Wind damage preventing advertising frame

Technical field

The utility model relates to the billboard frame field, specifically is meant the outdoor billboard frame.

Background technology

Advertising campaign is the important component part of modern commerce activity, the outdoor billboard frame then is the important component part of advertising campaign, they generally are plate shape, be installed on the buildings or stand on the circular post, wherein a kind of widely used form then is by mode that cylinder supports independently, because outdoor environment is relatively poor relatively under the plate that is rectangle, particularly under the wreaking havoc of strong wind, this kind billboard frame is repaired time-consuming consumption power because fixing installing often easily loses, and loses huge.

Summary of the invention

The purpose of this utility model just provides a kind of billboard frame of new departure, and it can eliminate above-mentioned deficiency to a large extent.

The technical program is achieved in that the recessed following pearl groove in top of an affixed ring-type on the periphery wall of the position of following mouthful of the close billboard on the column of circle, be arranged with steel ball in the pearl groove uniformly, it on the steel ball the last pearl groove of same shape, just concave surface is installed down, and the discord stud wall is affixed, the tubular article that one internal diameter is slightly larger than the column external diameter be following mouthful of sleeve and aforesaid on pearl groove top affixed, top at column is equiped with nut, one internal diameter stretches into greater than the lower end of the compression spring of sleeve outer diameter in the following hole clipping of strain groove below under being on the stud wall, and being in the last hole clipping above the pearl groove of sleeve lower end then stretched in the upper end; Square billboard is then affixed with sleeve, should make the vertical center line of billboard slightly depart from the axial line installing of column simultaneously.

The design's advantage is when wind comes, billboard can turn to automatically and make the direction of its length trend towards wind direction, like this then avoided damage in the former design because of the fixedly connected huge windage resistance that the windward side produced, after the abatement of wind or eliminating, the bullet torsion of spring can make plate return to design angle again, under cost increase situation seldom, improved its serviceable life, also can suitably regulate the steering angle of plate simultaneously according to needs.

Description of drawings

The overview that Fig. 1 gives an example for the design.

The partial sectional view that Fig. 2 gives an example for the design: partial enlarged views such as the column before the device rectangle billboard, sleeve, nut, among each figure, 1 is billboard, 2 is last hole clipping, 3 is sleeve, and 4 is last pearl groove, and 5 is steel ball, 6 are following pearl groove, 7 is spring, and 8 are following hole clipping, and 9 is column, 10 is footing, and 11 is nut.

Embodiment:

As shown in Figure 2, the circular groove of pearl up and down 4 and 6 of one pair of band groove that installs relatively up and down is installed on the periphery wall of column 9, wherein will descend the pearl grooved ring to be welded in the perisporium outside of column, the steel ball 5 of evenly distributed right quantity in the groove, last pearl groove 4 is pressed on the steel ball and installs, its internal diameter is bigger, the surface contact of discord column is affixed, one internal diameter is placed on the column from the column top greater than the tubular article sleeve 3 of column external diameter, the upper surface welding of its following mouth and last pearl groove 4, the height of sleeve is a little less than the upper end of column, and a nut 11 is fixed in the column upper end by the screw thread that matches simultaneously, it can stop sleeve on move; On the stud wall under the following pearl groove 6, be processed with hole clipping 8 down, the lower end pawl of one spiral spring 7 stretches in the hole clipping 8, the internal diameter of spring 7 is slightly larger than the external diameter of sleeve 3, the upper end is walked around up and down and is stretched in the last hole clipping 2 that is in pearl groove top on the sleeve behind the pearl groove again, and hole clipping can process many to putting the needs at angle to satisfy difference simultaneously up and down; At last billboard 1 is fixed on the sleeve 3, also should allow the vertical center line of billboard and the longitudinal center line of column not overlap simultaneously, it is asymmetrical unit, (right avertence as shown in fig. 1, the right-hand component that is billboard 1 is bigger, the left side is smaller), whole advertisement frame board is then affixed by base angle 10 and the earth under the column 9, the anti-damage billboard that the design like this gives an example is promptly installed and is finished, when strong wind blows, if wind direction is same as the length direction of plate, then the windage of Chan Shenging is minimum, and whole board maintains the original state; If wind direction is perpendicular to the big face of plate or be the wide-angle wind direction, then because asymmetric active connection of board face and column, plate and sleeve can be done to be tending towards the rotation of wind direction up to being same as wind direction around column under the cooperation of up and down pearl groove and steel ball naturally, this moment, windage can drop to 1/tens of former fixedly installing, greatly reduce the stressed of post board, avoided damage, after the abatement of wind or eliminating, the torsion of spring then can make plate set back automatically, does not influence demonstration effect at all.

Claims

1, a kind of wind damage preventing advertising frame, by column, billboard, sleeve, last pearl groove, following pearl groove, steel ball, spring is formed, the recessed following pearl groove in top that it is characterized in that an affixed ring-type on the periphery wall of the position of following mouthful of the close billboard on the column of circle, be arranged with steel ball in the pearl groove uniformly, it on the steel ball the last pearl groove of same shape, just concave surface is installed down, and the discord stud wall is affixed, the tubular article that one internal diameter is slightly larger than the column external diameter be following mouthful of sleeve and aforesaid on pearl groove top affixed, top at column is equiped with nut, one internal diameter stretches into greater than the lower end of the compression spring of sleeve outer diameter in the following hole clipping of strain groove below under being on the stud wall, and being in the last hole clipping above the pearl groove of sleeve lower end then stretched in the upper end; Square billboard is then affixed with sleeve, should make the vertical center line of billboard slightly depart from the axial line installing of column simultaneously.
