Abstract

The utility model discloses a scroll billboard. At least two closed-loop chains which are driven by synchronous chain wheels are arranged in a machine frame, and a track which is used for supporting the closed-loop chains and limits the movement of the closed-loop chains is fixed on the machine frame, wherein, the track is sectionally arranged between the synchronous chain wheels. An annular rotating advertisement picture is tensioned and hung between the closed-loop chains through a buckle appliance. The utility model can ensure the tension and the stable operation of the annular rotating advertisement picture without the affection of the outer disturbing force. Furthermore, the turning radius can be small, and the thickness can be small. Thus, the utility model is not only suitable for advertisement devices of various places of street lamp boxes, court advertisements, etc., but can be arranged on various dynamic carriers which comprise the vehicles.

Description

The rolling billboard

The utility model relates to a kind of advertising facility, especially a kind of billboard with dynamic rolling bandwagon effect.

Flourish along with advertising, multiple scheme has appearred in the advertisement facility of picture rolling, and wherein in use the easy sideslip of ubiquity picture, difficulty such as tighten at problem with the comparatively approaching ring-like band advertisement of the utility model.In addition, according to applicant retrieval, the applying date is that August 24, application number in 1998 are the new-type billboard that 98207847.1 Chinese patent " billboard " discloses a kind of picture rolling realized that is made of casing, closed loop tracks, small rail car etc.The chain rail structure of this product is similar substantially to the structure of industrial hook chain rail conveyor, and fixedly strip advertisement on its small rail car moves in ring-like chain track.Because small rail car moves in track, so advertisement picture is reliable.Yet because the track radius of turn of this structure can not be less than the minimal curve radius of dolly, the result causes the equipment integral size bigger, inapplicable slim rolling advertisement facility.

In addition, along with the development of advertising, automotive advertising has become important branch of outdoor advertising, is widely adopted because of it has very strong a surname's power of dying.Yet owing to there is vibration in the vehicle traveling process, existing advertisement facility is difficult to adapt to, and does not therefore occur the stronger Rolling vehicle advertisement facility of the power of playing up so far.

Given this, the purpose of this utility model is: a kind of compact conformation, reliable rolling billboard are provided, and this billboard decapacitation is applicable to outside the fixed-sites such as station, street, also should be able to be applicable to as on the dynamic carriers such as automobile.

For achieving the above object, at least two closed loop chain that driven by synchronous sprocket wheel are housed in the frame of the utility model rolling billboard, also be fixed with the track that supports and limit the chain operation on the frame, track section wherein is placed between the sprocket wheel, and stretching tight by fastener between the chain hangs with ring-like rotation advertisement picture.In the use, when power drive two chain run-in synchronisms, chain drives the advertisement picture circumduction by fastener, forms the rolling advertising results.Because the chain constrained by rail between sprocket wheel that is connected at interval with small rail car is supported by sprocket wheel again outside track, can guarantee that therefore advertisement picture tightens all the time, running is not subjected to the influence of external disturbance power reposefully.In addition, at the chain turning, the small rail car constraint that de-orbits, so radius of turn can be very little, thickness can be thinner.Good resistance to shock and compact structure make rolling billboard of the present utility model can be installed on the various dynamic carriers that comprise vehicle, and the scope of application is extensive.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of embodiment one of the present utility model.

Fig. 2 is the structural representation of Fig. 1 embodiment track and chain and small rail car junction.

Fig. 3 is the structural representation of embodiment two tracks and chain and small rail car junction.

Fig. 1 is a kind of rolling billboard of small breadth.Its main member organic frame 1, track 8, closed loop chain 7, small rail car 4, sprocket wheel 3, axle 2, advertisement picture 10, draw button 11, spring 6, propulsion system 9 etc.Wherein, advertisement picture 10 is tensioned to up and down between the parallel annular chain 7 by drawing button 11 and spring 6 hooks.Chain 7 is driven by rack-mounted sprocket wheel 3.Track 8 segmentations are fixed on the frame between the sprocket wheel 3.Chain 7 the part between the sprocket wheel 3 by with its small rail car that is connected at regular intervals 4 bearings in track 8.As seen from Figure 2, the chain 7 of present embodiment directly is connected with the small rail car 4 of band roller by the lengthening bearing pin.

During work, propulsion system 9 are gone up lower sprocket 3 by axle 2 drives and are synchronized with the movement, and advertisement picture 10 is rolled change face.Since last lower chain 7 symmetries, the motion strict synchronism, so advertisement picture 10 is smooth all the time, keeps good form.Draw button 11 and spring 6 as fastener and adopt, then reduced the making accuracy requirement of advertisement picture 10, operability is good.In addition, because at sprocket wheel 3 places, small rail car 48 constraints that de-orbit, so the radius of turn of chain track can be very little make this billboard thin thickness, and volume is little, is convenient to flexible laying, and helps the storage of multi-picture.Experiment showed, that the required driving force of this billboard is little, flexible operation, steady, noise is little, and its scope of application is extensive.

The difference of embodiment two and embodiment one as shown in Figure 3, chain 7 in the direct bearing of the part between the sprocket wheel 3 in track 8.This spline structure is simpler and more direct, and manufacturing cost is more economical.

In addition to the implementation, the utility model can also have many versions, and the track 8 of for example segmentation is a curve shape, has more relief rolling advertisement picture thereby form.For another example, chain 7 is connected by the small rail car 4 of carrier bar with the band roller.And so on, all belong to protection domain of the present utility model.
