CN2146040Y - Mechanical cartoon effect demonstrator with variable pictures - Google Patents

Abstract

The utility model discloses a mechanical cartoon effect demonstrator with variable pictures, composed of a motor and an indication mechanism comprising a belt gear, a driving rotary column with multi-arris surfaces or a drop-in leaf driven by a retarding mechanism. The belt gear is composed of a belt pulley, a belt, a transmission bar fixed on the belt and a transmission pulley fixed on the indication mechanism and matched with the transmission bar. The length of the transmission bar is at least the required length of a transmission picture in the indication mechanism driven by the transmission pulley. The utility model can make every display surface change pictures in turn to get cartoon or wave mobile effect.

Description

Mechanical cartoon effect demonstrator with variable pictures

The utility model relates to the variable picture mechanical display devices, and relating in particular to picture is upset successively successively, with the mechanical display devices that realizes that animation effect and wave picture show.

Existing display device is generally the fixedly billboard formula of single width.Because it can only show a width of cloth picture regularly, capacity is little, and is dull inflexible, do not satisfy the needs of growing advertising cause far away.Though the electron optics advertisement display capacity of up-to-date appearance is big, it is colorful to change irregularly, and is rich in innervation, is much better than the fixedly billboard of single width on the effect, and its expensive price to the environmental requirement height, still is difficult to popularize.Also have a kind of variable picture mechanical display devices in addition, it mainly is made of the indication mechanism that motor, speed change intermittent drive mechanism, many faceted pebbles rotary column or drop in leaf constitute.Each display surface at many faceted pebbles rotary column or drop in leaf is arranged different pictures, make it to show within a certain period of time certain combined picture, the picture conversion of each display surface is carried out simultaneously then, therefore the capacity that shows and dynamic aspect all obviously superior than the fixed billboard formula of single width, but still lack the variation of continuity and strong innervation, still seem dull.

The purpose of this utility model provides the mechanical display devices of a kind of variable picture animation or wave effect, each display surface of forming picture is sequentially and rotational transform, thereby make the conversion successively of each display surface, utilize the persistence of vision effect of human eye, obtain animation effect, perhaps can obtain awave effect.

The purpose of this utility model is achieved in that variable picture animation effect mechanical display devices, motor and reducing gear are arranged, the indication mechanism that many faceted pebbles rotary column or drop in leaf constitute, the belt gear that motor and reducing gear drive, and then drive indication mechanism conversion picture.Belt gear is by belt pulley, belt, is fixed on transmission bar on the belt, power wheel that cooperate with the transmission bar, that be fixed on the indication mechanism constitutes.The length of transmission bar is minimum to make length that picture is required of indication mechanism conversion for driving power wheel.

The utility model will be further described below in conjunction with accompanying drawing.Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the utility model detent mechanism structural representation.Wherein (1) is three faceted pebble rotary columns, and (2) are the transmission bars, and (3) are belt pulleys, and (4) are belts, and (5) are carrier wheels, and (6) are power wheels, and (7) are locating wheels, and (8) are backstays, and (9) are springs.With reference to the accompanying drawings 1, motor rotates by reducing gear (as adopting train of reduction gears) drive pulley (3), thereby drive belt (4) motion, and fix a transmission bar (2) (available one section flexible rack or toothed chain or vee belt etc.) on the belt (4), transmission bar (2) cooperates (power wheel can be gear, sprocket wheel or belt pulley) with power wheel (6) on the rotary column (1) again, the length of transmission bar (2) just makes power wheel (6) rotate 120 ° angle, makes three faceted pebble rotary columns (1) just rotate a faceted pebble.Belt (4) is being with transmission bar (2) moving linearly from left to right, just makes each rotary column (1) in turn rotate 120 ° from left to right.Carrier wheel (5) is as the location and the tensioning of belt.The frequency of each rotary column conversion picture and speed can be determined by the speed ratio that changes reducing gear.(2) with reference to the accompanying drawings, with the coaxial locating wheel (7) that is equipped with of power wheel (6), locating wheel (7) has recess in a picture institute of rotary column conversion rotational angle corresponding position, is combined with backstay (8) with locating wheel (7), and backstay (8) is subjected to spring (9) effect.Backstay (8) snaps in the recess of locating wheel (7) under the effect of spring (9), make picture displayed over against the place ahead, realizes the location.The size of recess and acting force of the spring should make rotary column (1) can rotate smoothly under the effect of transmission bar (2), prevents being rotated further of rotary column (1) reliably after transmission bar (2) effect is finished.

The utility model has been realized each display surface of indication mechanism conversion picture successively, utilizes people's persistence of vision effect, obtains the wave effect or is similar to the visual effect of cartoon type.Simple and reliable for structure, novel and high-efficiency.Its propaganda display effect is rich dynamic.

Claims (4)

1, variable picture animation effect mechanical display devices, the indication mechanism that has motor and reducing gear, many faceted pebbles rotary column or drop in leaf to constitute, it is characterized in that having the belt gear of motor and reducing gear drive, said belt gear is by belt pulley, belt, be fixed on transmission bar on the belt, biography wheel that cooperate with the transmission bar, that be fixed on the indication mechanism constitutes, and the length of transmission bar is minimum to make length that picture is required of indication mechanism conversion for driving power wheel.

2, variable picture animation effect mechanical display devices according to claim 1 is characterized in that said transmission bar can be a flexible rack, and the power wheel of Pei Heing is a gear with it.

3, variable picture animation effect mechanical display devices according to claim 1 is characterized in that said transmission bar can be a driving belt, and the power wheel of Pei Heing is a belt pulley with it.

4, according to claim 1 or 2 or 3 described variable picture animation effect mechanical display devices, it is characterized in that and the coaxial detent mechanism that spring constituted that locating wheel, the backstay that cooperates with locating wheel is installed, acts on backstay of power wheel, have recess in picture institute gyration corresponding position of conversion on the locating wheel, backstay snaps in said recess under the effect of spring, make picture displayed over against the place ahead.
