Abstract

The utility model provides a circulating showing advertisement drawing box with large capacity. The utility model is characterized in that a wire rope driving device is arranged in a framework type frame; a motor of the wire rope driving device drives a coaxial driving corner wheel and a guiding wheel to rotate through a synchronous belt retarding mechanism, and thus an upper and a lower wire ropes circularly move around the corner wheel and the guiding wheel. Interlink drawing canvas are clamped on the wire ropes in an equidistance mode through many small pulley cranes and move along with the wire ropes to show the interlink drawing canvas; one end of each small pulley crane is buckled on a T-shaped guide way, and the other end is connected with the interlink drawing canvas. Compared with the existing advertisement devices, the utility model has the advantages of large capacity, low cost, continuous show, etc., and is suitable for showing large-scale advertisements.

Description

Large capacity circulating advertising printing support

The utility model relates to a kind of advertisement poster extending apparatus, and exhibition advertisement poster case is put in particularly a kind of high capacity circulation, is suitable for advertisement capacious and uses.

In prior art, show that the device of advertisement mainly contains three kinds: steelframe is fixed, little triangular discontinuities rotary type and computer giant-screen (LED electronic display curtain).First kind of cost is minimum, but capacity is little, and dullness is inconspicuous, weak effect; Though can intermittently show three advertisements for second kind, cost is higher, and between each triangle the slit is arranged, image quality is bad, and effect is undesirable; The third effect is best, and capacity is big, the easy conversion of picture, and also bright in colour, but cost is very high, and power consumption is big, and failure rate is difficult to apply than higher.

The purpose of this utility model is to overcome the deficiency of prior art, provides the high capacity circulation that a kind of capacity is big, cost is low, the exhibition of can circulating is continuously put to put exhibition advertisement poster case.

Task of the present utility model realizes by this way: this advertisement cabinet is mainly by frame, motor, be with reducing gear synchronously, initiatively corner is taken turns, the corner wheel, the active angle sheave, passive angle sheave, T type guide rail, wire rope, pulley telpher and a chain of painting canvas are formed, frame is the rectangular parallelepiped of a framed structure, being provided with a pair of coaxial active corner wheel and two pairs in two corners of the corner of one end and the other end up and down respectively takes turns with Shaft angle, on the corner wheel, the two ends of lower plane also be provided with one group by many to coaxial active angle sheave to many to concentric passive angle sheave to constitute in order to increase the guide wheel group of a chain of painting canvas walking length, each one up and down of wire rope, crossing two pairs of corners wheels behind active corner wheel walks around every pair respectively at interval by the trend of a plurality of zig-zag types more initiatively angle sheave and passive angle sheave gets back to that initiatively the corner wheel is end to end, article two, T type guide rail is separately positioned on the above and below of wire rope according to wire rope run trace correspondence, the pulley telpher is equidistant being anchored on the wire rope at interval, and snap onto up and down on the T type guide rail with a pair of pulley on its top, a chain of painting canvas is also pressed the setting of wire rope run trace, fuse with wire rope with its upper and lower side and the binding of pulley telpher, initiatively corner is taken turns, the corner wheel, active angle sheave and passive angle sheave, have steel wire rope groove and with the identical gear teeth of pulley telpher pitch, motor is connected with the coaxial runner of corner wheel and active angle sheave initiatively by synchronous band reducing gear.

The utility model is like this work: advertisement poster pastes or directly is plotted in by on the open a chain of painting canvas of pulley telpher up and down, starter motor, band reducing gear and drive synchronously be corner wheel and initiatively angle sheave rotation initiatively, the wire rope of contact is with it walked about, walk around every pair respectively by zig-zag type from active corner wheel again through three pairs of corners wheels and initiatively get back to initiatively constantly walking of corner wheel circulation behind angle sheave and the passive angle sheave, a plurality of advertisement posters in the painting canvas can be put with the display port exhibition that low speed circulates in frame.

From structure of the present utility model as can be known, the picture of painting canvas is big, and painting canvas is very long, adopts common gear train to drive again, and therefore, it is big that compared with the prior art the utility model has an advertisement capacity, the advantage that cost is low and the exhibition of can circulating is continuously put.Be particularly suitable for exhibit halls, square and highway and do to show advertisement and the use of economy and trade information.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

Fig. 1 is a kind of concrete structure of the utility model cross-sectional schematic longitudinally.

Fig. 2 is along the cut-open view of A-A line among Fig. 1.
