Abstract

The utility model relates to a billboard with a plurality of pictures formed by lateral faces of triangular prisms which are divided into a plurality of groups, and each group is shifted by a driving wheel to slide and rotate in a rectangular guideway; the number of pictures can be 6, 9, 12,...... The billboard has the advantages of large number of publishing advertisements, smooth picture and small edge joint. The utility model can be used for advertising propaganda for large sport or busy locations. If a plurality of billboards are collected together and the fashion of group control is used, the propaganda effect is better.

Description

Overturn prismatic billboard

The utility model relates to the variable picture advertisement board that a kind of picture is combined into by the tri-prismoid side.

The billboard that tri-prismoid rotates around stationary shaft can only provide three pictures, and pivoted billboard picture is more, but the intensity of page or leaf sheet is relatively poor, the impact that is difficult to bear ball or human body, and the front of billboard need stay the page turning space.These reasons have limited the use occasion of pivoted billboard.

The purpose of this utility model provide a kind of by the tri-prismoid side be combined into picture but the variable picture number more than three billboard.

The purpose of this utility model is achieved in that it is made up of the tri-prismoid group, and what of tri-prismoid group are determined by the size of billboard and the size of tri-prismoid.In the tri-prismoid group of six these billboards of picture, tri-prismoid is four, and the end of four tri-prismoids is limited in the square rail.The axle of tri-prismoid is embedded in the shift fork of thumb wheel, and thumb wheel is four shift forks, and less angle is about 71 degree between shift fork, and spring is equipped with at each shift fork place, forces tri-prismoid to be close to square rail.Every replacing one subframe, thumb wheel is by gear train driven rotary 180 degree.In the tri-prismoid group of 12 these billboards of picture, tri-prismoid is eight, and the end of eight tri-prismoids is limited in the rectangular guideway.Thumb wheel is two, rotation in the same way synchronously, and five shift forks of each thumb wheel, the axle of tri-prismoid alternately embeds in the shift fork of two thumb wheels.In order to finish the handing-over of tri-prismoid between two thumb wheels like clockwork, the closed slide and the locating convex block that limit the triangular prism axon also are housed, also there is spring at each shift fork place, force tri-prismoid to be close to rectangular guideway, two thumb wheels of every replacing one subframe drive 144 degree of rotation synchronously by gear train.

Characteristics of the present utility model are:

1. when picture stopped, tri-prismoid all was close on the guide level, makes picture smooth, and piece is also little.

2. tri-prismoid only slides in guide rail and rotates, and tri-prismoid can not exceed plane, picture place when changing picture, even be close to picture glass is installed, and also can not influence rolling of tri-prismoid.

3. the variable picture number is many, and it is convenient to change tri-prismoid.

4. firm, shock-resistant.When ball or human body collision picture, spring (7) can play buffer action.

Further specify below in conjunction with drawings and Examples.

One. this billboard of six pictures: the roll synoptic diagram of mode of every group of tri-prismoid is seen Fig. 1. (8) are square guide rail among the figure.(1), (2), (3), (4) are four tri-prismoids, and the two ends of tri-prismoid are in the square guide rail of packing into.The end of tri-prismoid, but also size is slightly little.And three rolling bearings (9) can be installed, to reduce the friction force between end and guide rail.End size I slightly reduces the piece of picture between group and group.(5) be thumb wheel, four shift forks are arranged on the thumb wheel, the axle of four tri-prismoids (6) is embedded in four shift forks, and the angle on the thumb wheel between less two shift forks of angle is about 71 degree, the size of angle, two pieces between tri-prismoid will be influenced, piece is too small, can influence the rotation of tri-prismoid, and picture is spoilt, at four shift fork places, compression spring (7) (only drawing among the figure one) is housed all on the thumb wheel.The compression spring acting force forces four tri-prismoids to be pressed on all the time on the guide rail on the axle of tri-prismoid, and when changing picture, thumb wheel drives clockwise direction Rotate 180 degree (establish the right side and be the side towards spectators) by gear train at every turn.(3), (4) two tri-prismoids forward (1) to, and on the position of (2) two tri-prismoids, picture has produced once to be changed, and when thumb wheel when Rotate 180 is spent again, (1), (2) two tri-prismoids rotated back into original in the face of on the position of spectators' one side again.Sliding along guide rail when week, these two tri-prismoids counter rotation 120 degree.Make in the face of spectators be not original side, a but new side.Because tri-prismoid is sliding in the week, in the corner of each square rail, tri-prismoid is all wanted counter rotation 30 degree.During rotation, compression spring forces the incline of tri-prismoid to be bearing on the right angle rib of square rail, serves as that axle rotates with this rib.

Two. this billboard of 12 pictures: the roll synoptic diagram of mode of every group of tri-prismoid is seen Fig. 2, and (21) are rectangular guideway among the figure.(11), (12) ..., (18) are eight tri-prismoids.The two ends of tri-prismoid in the rectangular guideway of packing into, except rectangular guideway, also have closed slide (22), (23).Closed slide is used to guide the axle of tri-prismoid, makes the tri-prismoid that has broken away from thumb wheel still can be close to rectangular guideway and slides, and tri-prismoid is by two thumb wheels (19) that synchronously rotate (being clockwise direction among the figure) to same direction, and dial (20) changes.Five shift forks are arranged on each thumb wheel, and the angle of adjacent shift fork is 72 degree.Revolution changes a subframe, and thumb wheel is by gear train driven rotary 144 degree.Compression spring (7) (not drawing among Fig. 2) also is equipped with at each shift fork place, slides and rotates to force tri-prismoid to be close to rectangular guideway.For the axle that makes tri-prismoid can enter in the shift fork of another thumb wheel exactly, locating convex block (24) is housed, (25) on closed slide after breaking away from a thumb wheel.Locating convex block outwards protrudes with the elastic force of spring.When the axle disengaging shift fork of tri-prismoid, be subjected to the restriction of closed slide and the promotion of shift fork, the axle of tri-prismoid is pushed in the locating convex block and is accurately located.When the shift fork of another thumb wheel turned over, the axle of tri-prismoid embedded in this shift fork, thereby forwards in another thumb wheel, and stirred by another thumb wheel.

In service normally, tri-prismoid slides and 30 degree of counter rotation on the corner along the rectangular guideway clockwise direction, and the axle of tri-prismoid is caught by the shift fork of another thumb wheel again after breaking away from from the shift fork of a thumb wheel.

Behind square or rectangular guideway can be taken apart, in order to the replacing tri-prismoid, thereby upgrades the content that billboard publishes.

Because the utility model variable picture number is many, when many type billboards concentrate in together (for example in the venue in athletic meeting),, can cause bigger the effect of publicity if adopt the team control mode.For example at a time allowing on all billboards all is the advertisement of same enterprise.The advertisement that perhaps makes this enterprise is from left to right or from right-to-left, or sequentially occurs at each billboard from the center to the periphery or from the periphery to the center.Because this billboard picture is many, can organize picture with multiple mode when team control.
