Description
Technical Field
The utility model belongs to teaching and decoration goods of furniture for display rather than for use field relates to an utilize moire fringe to produce device of kinematical picture.
Background
Moire fringes are an optical phenomenon first discovered by mr moire of french researchers in the 18 th century. Technically speaking, moire is the visual result of interference between two wires or two objects at a constant angle and frequency. When the human eye cannot distinguish the two lines or objects, only the interference pattern is visible, and the pattern in this optical phenomenon is the moire fringes. Nowadays, people also make a plurality of dynamic pictures by utilizing the moire fringe principle, such as pictures of running courser, butterflies for flaring wings, big mouths for eating beans, tornadoes and the like which repeatedly act. The principle is that a grid film sheet which is transparent at uniform intervals is stacked on another grid drawing paper containing more than two pieces of pattern information, all patterns in the grid drawing paper are overlapped, and the same pattern is displayed at uniform intervals in sequence to form a pattern strip; the light transmission width between the grid bars of the grid bar film sheet is set to ensure that the grid bar film sheet can only penetrate through the picture of one pattern on the grid bar drawing paper, the grid bars block pictures of other patterns, the other pattern is exposed by moving the grid bar film sheet to block the previous pattern, and the patterns are sequentially and circularly displayed by continuously moving the grid bar film sheet, so that the effect of moving pictures is achieved. However, at present, the grid film sheet and the grid drawing paper are both manually stacked for demonstration, so that the grid film sheet cannot move circularly, and once the grid drawing paper is moved out, the movement is finished, or the movement is carried out again, or the movement is carried out reversely; and the grid in the grid film sheet is difficult to be aligned with the pattern strips in the grid drawing paper manually, so that the display effect of the motion picture is influenced.
Disclosure of Invention
The utility model provides a can last let moire fringe kinematical device of moving picture.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the Moire fringe dynamic demonstration device comprises a grid film sheet, grid drawing paper and a circulating operation device which enables the grid film sheet and the grid drawing paper to continuously move relatively, wherein two rotating shafts which are vertically arranged are arranged on the left and the right of the device, the rotating shafts have the same diameter, one of the rotating shafts is a driving shaft, the other rotating shaft is a tensioning shaft, and the driving shaft is connected with an output shaft of a speed reducing motor through a gear set; the grid film sheets are transversely connected end to form an annular belt sleeved on the driving shaft and the tensioning shaft; and arranging a pattern lamp box between the driving shaft and the tensioning shaft, wherein the thickness of the pattern lamp box is the same as the diameter of the driving shaft or the tensioning shaft, and the grid strip drawing paper is attached to one surface or two surfaces of the pattern lamp box.
The grid drawing paper comprises 3-4 continuous action patterns, and the animation effect is good.
The surface of the driving shaft is pasted with a rubber strip or a double-sided adhesive tape, so that slipping between the driving shaft and the grid strip film sheet can be avoided.
The utility model discloses a can conveniently demonstrate the moire fringe principle in succession, be a collection recreational, decorative, knowledge nature teaching device as an organic whole.
Drawings
Fig. 1 is a schematic structural view of a circulation operation device of the moire fringe dynamic demonstration device of the present invention.
Fig. 2 is a schematic view of an embodiment of the moire fringe dynamic demonstration apparatus of the present invention.
In the figure: 1. tensioning shaft, 2, drive shaft, 3, pattern lamp house, 4, gear motor. 5. Gear train, 6, rubber strip, 7, fixed axle, 8, bearing, 9, upper plate frame, 10, lower plate frame, 11, bottom plate, 12, pillar, 13, grid film sheet, 14, grid drawing paper.
Detailed Description
Fig. 1 is the utility model discloses circulation operation device structure sketch map, there are two vertical pivots of placing the same diameter about the device, one of them is drive shaft 2, and another is tensioning shaft 1, and drive shaft 2 and tensioning shaft 1 are installed between last grillage 9 and lower grillage 10 through coaxial fixed axle 7 respectively, go up grillage 9 and lower grillage 10 and link as an organic wholely through the pattern lamp house 3 that is located between drive shaft 2 and the tensioning shaft 1, the thickness of this pattern lamp house 3 with the diameter of drive shaft and tensioning shaft is unanimous. Each fixed shaft 7 is movably connected with the upper plate frame 9 and the lower plate frame 10 through four bearings 8. The above components are mounted on the base plate 11 by four support columns 12.
Wherein the fixed shaft 7 in the driving shaft is connected with the output shaft of the gear motor 4 through the gear set 5 so as to drive the driving shaft 2 to rotate, and the gear motor 4 is arranged between the lower plate frame 10 and the bottom plate 11. The speed reducing motor 4 adopts a motor with the rotating speed of about 5rap/min, and the rotating speed ratio of the gear set 5 is 5: 1; or a 1rap/min speed reducing motor and a gear set with a gear ratio of 1 can be adopted, or the output shaft of the speed reducing motor is directly connected with the fixed shaft 7.
The grid film sheets 13 are transversely connected end to form an annular belt which is sleeved on the driving shaft 2 and the tensioning shaft 1; one or two pieces of grid drawing paper 14 are adhered to one or both sides of the pattern light box.
In order to prevent the driving shaft 2 and the grid film sheet 13 from slipping, the driving shaft 2 can drive the grid film sheet 13 to circularly move, and the driving shaft 2 can be stuck with the rubber strip 6 or the double-sided adhesive tape.
The connection of the upper plate frame 9 and the pattern lamp box 3 can adopt a mortise and tenon structure insertion mode, so that the upper plate frame 9 can be conveniently taken down to replace the grid drawing paper 14 with different patterns. Two grid drawing paper can be connected into a cylinder to be sleeved on the pattern lamp box 3 in an ending way, the grid drawing paper 14 can be replaced more conveniently, and the two sides of the pattern lamp box 3 are provided with the moving pictures.
