Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of optical illusion phenomenon demonstrator, is specially a kind of diagonal of a parallelogram length optical illusion instrument.
Background technology
Optical illusion is when people observe some object, the false judgment to the object of observation formed based on empiricism or improper reference and perception.The kind of optical illusion has a lot, as geometry illusion, light and shade illusion, color illusion, shape illusion, illusion of movement, shade illusion etc.Optical illusion all has a wide range of applications in fields such as psychology, physiology, physics, design sciences.Design optical illusion is observed and identification device, is conducive to the content enriching activity to popularize scientific knowledge, excites student to probe into the interest of science secret.At present, the special demonstration equipment of various clear observation and resolution optical illusion is lacked.
Summary of the invention
The purpose of this utility model is a kind of diagonal of a parallelogram length optical illusion instrument designing the clear demonstration of energy and be conducive to illusion resolution.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: comprise base plate, the first stock, the second stock, the first quarter butt, the second quarter butt, the 3rd quarter butt, the first king-rod, the second king-rod, rotating shaft, the first block, the second block; Described first stock is equal with the length of the second stock, and the length of the first quarter butt, the second quarter butt, the 3rd quarter butt is equal; First stock, the first quarter butt, the second stock, the second quarter butt headtotail form a parallelogram and are fixed on base plate; 3rd quarter butt is located between the first stock with the second stock, parallel with the first quarter butt, the point of intersection of the first stock perpendicular bisector and the second stock is fixed in its lower end; The length of the first king-rod, the second king-rod equals the distance of intersection point to the first stock either end of the first stock perpendicular bisector and the second stock; Rotating shaft vertical base plate is fixed on the point of intersection of the first stock perpendicular bisector and the second stock; The lower end of the first king-rod and the second king-rod is separately fixed in rotating shaft can freely rotate around the shaft; First block and the second block are located at respectively and are close on the base plate of line below rotating shaft and the first two ends, stock left and right line; The shaft of the first king-rod and the second king-rod is movable by being located on the first block and the second block respectively, and the upper end of the first king-rod and the second king-rod lays respectively at the two ends, left and right of the first stock.
The angle of described second quarter butt and the second stock is less than or equal to 75 degree.
Owing to adopting above-mentioned design, the utility model can produce following beneficial effect: by the 3rd quarter butt, the parallelogram that first stock, the first quarter butt, the second stock, the second quarter butt headtotail are formed is divided into two into left and right two parallelogram, first king-rod and the second king-rod are respectively the diagonal line of these two parallelogram, now, the diagonal line (i.e. the first king-rod) of left side parallelogram seems obviously long than the diagonal line (i.e. the second king-rod) of the right parallelogram, forms optical illusion thus.Rotate around the axis the first king-rod to the second king-rod position, or rotate the second king-rod to the first king-rod position, or rotate the first king-rod simultaneously and make it to overlap with the second king-rod, compared by length, known first king-rod of observer is equal with the length of the second king-rod, can judge that this diagonal line length is optical illusion illusion thus.The utility model can hang on all kinds of scientific and technological venue, can clear demonstration and start to differentiate optical illusion, is conducive to deepening understanding to optical illusion phenomenon.
Accompanying drawing explanation
