Abstract
The utility model discloses a mechanical display device with changeable picture, which is composed of a display board, a motor and a transmission mechanism. The display board is composed of the external plane surfaces of a plurality of equilateral triangular prisms which are arranged in axial in parallel. The equilateral triangular prisms respectively simultaneously intermittently rotate winding rotation shafts under the driving of the motor and the transmission mechanism. The plane surface of the display board recombine once when the equilateral triangular prisms rotate once, therefore, the mechanical display device with changeable picture can display three different pictures in alternation and has the advantages of simple structure and low cost compared with display devices which are controlled by electronic technology for changing the pictures. The utility model is a borne for large-sized billboards.
Description
The utility model belongs to the mechanical type display device.
Existing display device as uses such as advertisings can be divided into picture fixing with variable two types of picture, the former makes plate object with metal, plastics, timber etc., directly on the plate face, draw a picture, simple in structure, cost is low, but can only show a fixed image; The latter adopts electronic technology control usually, by changing pixel conversion picture arbitrarily, but complex structure, the cost height.
The purpose of this utility model is to provide a kind of can show several different pictures by turns, and mechanical type display device simple in structure, that cost is low.
The related display device of the utility model is made up of display board, motor and gear train, and wherein the outerplanar of the display board equilateral triangle prism being arranged, can be swayed separately by several axially parallels combines.
For making display frame stable, effective, indexing mechanism is set in gear train, all equilateral triangle prisms are done intermittently to rotate synchronously under gear train drives separately around the shaft, and each rotation process turned over for 1/3 week.
The utility model can show three different pictures by turns, and is simple in structure, cost is low, is particularly suitable for as large board.
Below in conjunction with drawings and Examples the utility model is described in detail.
Accompanying drawing 1, display device structure synoptic diagram (a) are front elevation, (b) are right side cross-sectional view.
As can be seen from the figure, behind the rotation of motor (1) the process speed reduction unit (2), drive indexing mechanism (3) motion.Here indexing mechanism has adopted Geneva mechanism, and driving wheel is established a pin on (3.1), establishes the radial slot of n symmetry on the sheave (3.2), and when driving wheel (3.1) changeed 360 °, sheave (3.2) changeed 360 °/n.When under the effect of indexing mechanism (3), forming one with the coaxial sprocket wheel I (4) of sheave (3.2) and rotate, the time and the geneva motion that stops, the ratio of rotation time and stand-by time can be adjusted by the diameter that changes driving wheel (3.1).Sprocket wheel I (4) is intermittently moved this by chain (5) and is passed to several and be installed in sprocket wheel II (8) in a certain side rotating shaft of each equilateral triangle prism (9) with one heart, thereby equilateral triangle prism (9) is also just done intermittently to rotate synchronously under the drive of sprocket wheel, chain separately around the shaft.In mechanism design, make the each angle of rotating of ratio of gear between sprocket wheel I and the sprocket wheel II and sheave (promptly 360 °/n) long-pending be 120 °, promptly guarantee equilateral triangle prism (9) at every turn rotation process turned over for 1/3 week.The rotating shaft two ends of all equilateral triangle prisms (9) are supported by a frame (10), make the rotating shaft of each equilateral triangle prism (9) be located along the same line, and the rotating shaft core between per two triangular prism bodies is apart from the length of side that equals the triangular prism body.Adjust the position (angle) of each equilateral triangle prism (9) when mounted, make when they do intermittently to rotate under gear train drives, whenever rotation stops, their a certain corresponding outerplanar place just is combined into a bigger plane display board at grade.Because triangular prism body (9) is equilateral, thereby two corresponding outerplanars also can form kindred circumstances in addition.Utilize and various means such as to draw, to paste, inlay and on display board (being each corresponding outerplanar of equilateral triangle prism), make required picture, under motor and gear train drive, at regular intervals, the plane of display board just reconfigures once, thereby picture also with regard to conversion once, and three picture circulations show.
Stretching pulley among the figure (6) is the tightness that is used for regulating chain (5).The effect of transition wheel (7) is to change the cornerite of chain (5), makes the running of sprocket wheel II (8) steady, and is reliable.Equilateral triangle prism (9) can be used various material such as metal, plastics, hollowly or solid all can, as long as can guarantee the unlikely distortion of the rigidity of itself, its size and number can decide according to the size of need display frame, can be as accompanying drawing 1(a) shown in transversely arranged, also can uprightly arrange (this moment gear train, frame will be adjusted accordingly).Speed reduction unit (2) can adopt reducer of turbodrill, also can adopt other form such as harmonic speed reducer etc.Reduction gear ratio can be calculated as follows:
Reduction gear ratio i=(motor speed (rev/min))/(per minute needs the number of times of conversion picture) indexing mechanism (3) also can adopt intermittent gear and star-wheel mechanism etc. except that adopting Geneva mechanism.Chain (5) adopts common bush roller chain to get final product.
Claims (2)
1, a kind of mechanical type display device of convertible picture is made up of display board, motor and gear train, it is characterized in that the outerplanar of the equilateral triangle prism that display board is arranged, can be swayed separately by axially parallel combines.
2, mechanical type display device as claimed in claim 1 is characterized in that being provided with indexing mechanism in gear train, all equilateral triangle prisms are done intermittently to rotate synchronously under gear train drives separately around the shaft, and each rotation process turned over for 1/3 week.
