Abstract

The utility model discloses a variable information billboard, which is composed of an electric motor, a retarding mechanism, an eccentric wheel, a gram pump wheel, a flywheel, drive chains, a shifting axle head and equilateral triangular prisms. The billboard face of the variable information billboard is composed of a plurality of the equilateral triangular prisms. The corresponding faces of the equilateral triangular prisms form one picture. The equilateral triangular prisms can simultaneously synchronically rotate 120 DEG, and can also ordinally sequentially rotate 120 DEG for transforming the advertisement picture. The utility model can transform one picture when rotating 120 DEG, and can transform out three pictures in all. The variable information billboard has multiple angle display, small area and large information quantity because of being made as the billboard with a plurality of boards.

Description

Variable information billboard

The utility model belongs to the billboard of variable information.

In the existing various billboards class be can not information converting billboard, its information directly is plotted on the billboard, the content dullness, the replacement cycle is long; Another kind of is the billboard that utilizes TV tech to make, the various novelty of its content, but cost is higher, be not easy to a large amount of employings, also having a class is that mechanical variable changes the billboard of information such as picture that CN2030358 the provides billboard from line translation and Activity Show device, and it is by being plotted in advertisement on the travelling belt and utilizing mechanical drive principle to realize that picture is from line translation.

The purpose of this utility model be to provide a kind of simple in structure, move flexibly, capacity is big, shows that the many variable information billboards of angle show mass advertising information with small size.

The utility model is by realizing with lower device, the variable information billboard is that the respective face by many groups of equilateral triangular prisms constitutes, each equilateral triangular prism all is fixed on to be stirred on spindle nose and the supporting spindle nose, drive unit drives speed reduction unit, drive the gram pump impeller, stir spindle nose through driving-chain and rotate 120 °, realize simultaneously conversion synchronously; Drive unit drives speed reduction unit and drives flywheel again and stir through compound driving-chain and compoundly stir the spindle nose realization and change in proper order; Each equilateral triangular prism respective face can be formed a width of cloth picture, and three faces can be formed three width of cloth pictures altogether, and equilateral triangular prism revolution can form a width of cloth picture for moving 120 °, can form three width of cloth pictures altogether.

Below in conjunction with accompanying drawing the utility model is described in detail as follows:

The variable information billboard of Fig. 2 for overturning synchronously or overturning continuously;

Fig. 3 is the variable information billboard of multiaspect;

Fig. 4 is a length greater than 2 meters variable information billboard;

Fig. 5 (a), be variable double sided informative advertising board;

(b), be triangle variable information billboard;

Fig. 7 is continous way upset variable information billboard speed reduction unit and gearing synoptic diagram;

Fig. 8 is the compound spindle nose and the scheme of installation stirred of variable information billboard;

Fig. 9 grows up in the connection spindle nose and the scheme of installation of 2 meters variable information billboard for triangular prism;

Figure 10 is the equilateral triangular prism sectional schematic diagram of variable information billboard.

In Fig. 1, motor 1 drives worm screw 2 and drives worm gear 3 again, make 1800 rev/mins of speed of 20 rev/mins that are kept to straight-tooth gear 4 of rotating speed of motor 1, straight-tooth gear 4 drives eccentric gear 5, making eccentric gear 5 rotating speeds is 10 rev/mins, 6 promotions of cranking arm restrain pump impellers 7, turn a fixed angle at every turn, drive by driving-chain with the coaxial straight-tooth gear 8 of gram pump impeller 7 and to stir spindle nose 9(such as Fig. 6) rotate, 120 ° of each rotations, thereby make equilateral triangular prism rotate 120 °, the two ends of equilateral triangular prism are separately fixed at stirs on spindle nose 9 and the supporting spindle nose 10, stir spindle nose and concentrate an end that is fixed on equilateral triangular prism, driving-chain whenever moves a segment distance, and all equilateral triangular prisms all rotate 120 ° synchronously.

Figure 7 shows that the speed reduction unit and the gearing of continous way upset variable information billboard, this gearing inner structure also is a worm screw, worm gear and straight-tooth gear, and it is identical with speed reduction unit shown in Figure 1; Eccentric wheel 5 is coaxial among flywheel 11 among Fig. 7 and Fig. 1, its rotating speed is 10 rev/mins, flywheel 11 drives compound spindle nose 12(such as Fig. 8 of stirring by the combined type driving-chain), rotate an angle, the combined type driving-chain is made up of main chain and auxilliary chain, main chain is the ordinary bicycle chain, auxilliary chain is one section bicycle chain, and with this section bicycle chain with the main chain chain riveting, main chain is on the compound flywheel 13 of stirring spindle nose 12, flywheel 13 is free to rotate and do not influence and stir spindle nose 12 and rotate, when the auxilliary chain of compound driving-chain passes through flywheel 14, promptly stir spindle nose 12 and rotate an angle, its rotational angle is decided with the length of compound driving-chain middle berth chain, the compound chuck 15 of stirring spindle nose 12 is a disk with three semicircle recesses, three recesses are evenly distributed on the disk edge, 16 is register pin, its inside is the steel ball 17 of a band spring, stir moving 120 ° of spindle nose 12 revolutions, just but fastening is on register pin 16, steel ball 17 snaps in the semicircle recess of chuck 15, make the corresponding face keeping parallelism of all equilateral triangular prisms, in the auxilliary chain institute of compound driving-chain through part, auxilliary chain is stirred the corresponding compound spindle nose of stirring, and makes equilateral triangular prism rotate 120 ° successively continuously.

For the variable information billboard of triangular prism length greater than 2 meters, as Fig. 4, can adopt to connect supporting spindle nose 19 at seam crossing 18, supporting spindle nose 19 is fixed on the bearing support 20, leaves the gap between the triangular prism at two ends, so that the arm of bearing support 20 passes from the gap.

Drive motor adopts the interruptedly supplying power mode, finish interruptedly supplying power with relay or timing circuit to motor, after making each rotation there is 10～20 seconds idle hours, thereby make each picture that certain remaining time can be arranged, being convenient to spectators sees clearly, equilateral triangular prism can be made with sheet iron, plank or plastics, and its section as shown in figure 10; Nearest part was at a distance of 2 millimeters between equilateral triangular prism was arranged.

Embodiment of the present utility model as shown in Figure 2, this is a kind of single face billboard, form a width of cloth advertisement picture by the respective face of 24 triangular prisms, stir spindle nose and be installed in the bottom, 4 meters of billboard face widths, high 1 meter, equilateral triangular prism can rotate 120 ° simultaneously and change picture, also can from one end to the other side rotate 120 ° continuously successively, forms new picture.

Fig. 3, Fig. 4 and variable information billboard shown in Figure 5 are this programme embodiment also, Figure 3 shows that 6 variable information billboards, and each face wherein all is to be made of a plurality of equilateral triangular prisms, can be kept upright in the middle of the square; Variable information billboard shown in Figure 5 is to be used for having of shop sign can be fixed on the wall on one side, and billboard shown in Figure 4 is a length greater than 2 meters billboard, long 3.6 meters of this billboard, and high 1.5 meters can be overturn from top to bottom synchronously, also can order upset successively.

The utility model compared with prior art has the following advantages: the memory information amount is big, can move freely, and shows that angle is many, has a fashion style, cost is low, easy to maintenance.
