Description

Can change the portable advertisement cabinet of picture automatically

Technical field

The utility model belongs to the convertible advertising device of picture, particularly can change the portable advertisement cabinet of picture automatically.

Background technology

At present, in the hotel, doorway, public arena such as market, supermarket, exhibition is provided with the billboard that is used to release news more, the picture of this billboard is stationary state, lack dynamic, the content of showing on the picture is single, and can the amount of releasing news few, advertising results be very desirable.For this reason, people have developed the convertible advertising device of some pictures, be provided with main in the casing of these advertising devices respectively, driven cylinder, leading, reeling respectively on the driven cylinder and be painted with the flexibility band of advertisement poster on it, control the master respectively by two motors, driven cylinder rotates, the two receipts one is put, get final product the circularly exhibiting advertisement picture, though the advertising message that its weak point is such advertising device shows is many, the advertisement picture of showing is non-exchange, show that content is comparatively single, and its complex structure, volume is big, and cost of manufacture is very high, be used for the issue of outdoor large advertisement more, limited its use occasion.

The utility model content

The purpose of this utility model is to provide a kind of portable advertisement cabinet that can change picture automatically, not only can change the displaying picture at any time, show that content is versatile and flexible, and it is simple in structure, volume is little, in light weight, low production cost both can be used for the issue of outdoor advertising, also can be used for the issue of indoor advertisement, be not subjected to the restriction in place, the application scenario is extensive.

The purpose of this utility model is achieved in that a kind of portable advertisement cabinet that can change picture automatically, comprise the casing that has view window, in casing, present, on the layout of following horizontal interval, lower roller and motor, reduction gearing by electric-motor drive is being set on the roll shaft of lower roller one sidepiece, lower roller rotates by beaming roller in the flexible circumferential transmission, the length of the width of flexible circumferential and beaming roller roll surface is complementary, on the outside surface of flexible circumferential two vertical zone faces, the bottom is horizontally set respectively and the advertisement poster clamp bar, on the homonymy, advertisement poster in clamping between the following clamp bar, at least on the flexible circumferential zone face that is positioned at middle part, lower roller bottom surface, the positioning convex that stretches out is being set downwards, on the bottom surface of casing, be provided with respectively near the switch and the time relay, corresponding near switch with the position of positioning convex, link together by the time relay and electric electromechanics near switch.

During use, turn-on time relay power supply, the time relay work that picks up counting, timing finishes, the corresponding contacts closure of the time relay, the power supply of connection motor, motor slowly rotates by the reduction gearing drive lower roller that is installed on the lower roller roll shaft, lower roller drives by flexible circumferential again and goes up the beaming roller rotation, and like this, the advertisement poster that is installed in the vertical zone face of the flexible circumferential outside just can rotate displaying.When the positioning convex on being arranged on the flexible circumferential zone face forwards to again and locates near the position of the switch, near switch motion, cut off the circuit of motor, the motor stall, the time relay picks up counting again, and timing finishes, and connects the circuit of motor, motor begins again to rotate, and drives advertisement poster continuation rotation and shows.The utility model is when work, and the motion state of advertisement picture is to be association of activity and inertia, and is easy to attract people's notice, can open the replacing advertisement picture to the advertisement poster clamp bar at any time, thereby show that content is versatile and flexible, good advertising effect, it is simple in structure, and volume is little, and is in light weight, be easy to hang, low production cost both can be used for the issue of outdoor advertising, also can be used for the issue of indoor advertisement, be not subjected to the restriction in place, the application scenario is extensive.

Embodiment

A kind of portable advertisement cabinet that can change picture automatically, as Fig. 1, Fig. 2, shown in Figure 3, comprise the casing 2 that has view window 3, upper and

lower beaming roller

4,10 and the motor 15 that in casing 2, goes to upper and lower the horizontal interval layout, motor 15 is installed on the tank wall of casing 2 lower side, and motor 15 should be selected miniwatt, slow-revving motor for use.Reduction gearing 14 by motor 15 transmissions is being set on the roll shaft of lower roller 10 1 sidepieces, and lower roller 10 rotates by beaming roller in flexible circumferential 7 transmissions 4, and flexible circumferential 7 is plastic tape or belt or strap.The length of the width of flexible circumferential 7 and beaming roller roll surface is complementary.As Fig. 2, shown in Figure 3, be horizontally set respectively in the outside surface upper and lower part of 7 liang of vertical zone faces of flexible circumferential and advertisement poster clamp bar 6,11, clamp bar 6,11 can be selected xsect common on market plastic clip triangular in shape or metal clip for use, and advertisement poster 8 in clamping between the upper and lower clamp bar 6,11 of homonymy.At least the positioning convex 12 that stretches out is being set being positioned on flexible circumferential 7 zone faces at lower roller 10 bottom surfaces middle parts downwards, certainly, can also on relative flexible circumferential 7 zone faces that are much of beaming roller 4 end faces middle part, also installing a positioning convex with positioning convex 12.On the bottom surface of casing 2, be provided with respectively near the switch 13 and the time relay 18, corresponding near switch 13 with the position of positioning convex 12, be electrically connected by the time relay 18 and motor 15 near switch 13.Can select for use near switch 13 forms such as condenser type or inductance type near switch.If a positioning convex only is installed, the advertisement picture that then is installed in flexible circumferential 7 zone face both sides shows continuously, if a positioning convex is installed respectively at the upper/lower terminal of flexible circumferential 7, and two width of cloth advertisement pictures picture-by-picture show that will pause at interval then.

As Fig. 2, shown in Figure 3, in order to prevent that advertisement poster 8 from damaging owing to unbalance stress produces the process of overturning from beaming roller, affixed at least two spaced springs 5 on last clamp bar 6, the other end of spring 5 all is fixed on the zone face of flexible circumferential 7 by fixture 17.Like this, advertisement poster 8 in the process of upset, spring 5 stretcher strain in advance, thus prevent that advertisement poster 8 from damaging because of producing stretcher strain.Certainly, spring 5 also elastic body such as available bungee replace.

In addition, in order to make the utility model institute advertisement content also can as Fig. 2, shown in Figure 3, on casing 2 inwalls of flexible circumferential 7 both sides, illuminating

lamp tube

9,16 be set vertically respectively for people clearly see at night.

As Fig. 1, Fig. 2, shown in Figure 3, in the both sides of casing 2 end faces adjustment bolt 1 is being set vertically respectively, adjust the bottom that bolt 1 is positioned at casing 2 bearing seat be set respectively, the two ends of last beaming roller 4 roll shafts respectively by Bearing Installation in described bearing seat.Adjust bolt 1 by rotation, beaming roller 4 is promoted or decline, thus can the appropriate rate of tension of adjusting flexible circumferential 7.

As shown in Figure 4, Push switch SB2, auxiliary reclay KA connects circuit, the time closing normally opened contact KT2 closure of time relay KT, and motor rotates, when contact-making switch K disconnects, time relay KT outage, relay K M also cuts off the power supply, the motor stall, when contact-making switch K was closed, time relay KT energising picked up counting again.Push switch SB1, then The whole control down circuitry.
