Description
Technical field
The utility model belongs to experimental demonstration device technical field, relates to a kind of optical illusion Phenomena Observation and identification device, is specially a kind of horizontal vertical illusion scope.
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.
Horizontal vertical illusion (horizontal-vertical illusion) is a kind of typical optical illusion phenomenon, it is when equal, the orthogonal line segment of horizontal, vertical two length forms inverse-T-shaped, vertical line seems longer than horizontal line, but in fact vertical line and horizontal line are isometric.At present, the Special Equipment of this horizontal vertical illusion of a kind of clear discriminating is lacked.
Summary of the invention
The purpose of this utility model is the horizontal vertical illusion scope designing the clear demonstration of a kind 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 rectangle base plate, cross bar, montant, rotating shaft, described cross bar is fixed on base plate middle and lower part along base plate long side direction; Montant is made up of the body of rod and the telescopic head being located at body of rod head, and the total length of the body of rod and telescopic head equals the length of cross bar, and wherein body of rod length is not less than 3/5 of cross bar length; Rotating shaft vertical base plate is located on cross bar perpendicular bisector, and rotating shaft equals 1/2 of cross bar length to the vertical range of cross bar; The body of rod is by rotating shaft and base plate rotation-coupled, and the body of rod and rotating shaft junction equal 1/2 of cross bar length to the distance of body of rod afterbody; Time initial, montant is positioned on cross bar perpendicular bisector, and telescopic head is also all pull-outs upward, and montant and cross bar form inverse-T-shaped optical illusion pattern.
Preferentially, the body of rod length of described montant is 2/3 of cross bar length, and telescopic head total length is 1/3 of cross bar length.
The utility model, owing to adopting above-mentioned design, can produce following beneficial effect:
Gone to by montant on cross bar perpendicular bisector, telescopic head is also all pull-outs upward, can form inverse-T-shaped horizontal vertical illusion pattern by montant and cross bar.When observing this pattern, montant seems obviously long than cross bar, forms optical illusion.Montant is gone to horizontal level around the shaft, and now montant is parallel with cross bar, and left end and the right-hand member of montant and cross bar align respectively, and their length is obviously equal, differentiates horizontal vertical illusion thus.
Observer also can first make montant and cross bar form inverse-T-shaped optical illusion pattern, then regulates the length of the telescopic head on (shortening) montant, until montant seems equal with the length of cross bar.Then montant is gone to around the shaft horizontal level to compare as length with cross bar, now the length of apparent montant is less than cross bar, differentiates horizontal vertical illusion thus.
The utility model can hang on all kinds of scientific and technological venue, by eye observation and the hands-on of observer, is conducive to deepening observer to the understanding of horizontal vertical illusion phenomenon.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is formation schematic diagram of the present utility model.
Fig. 2 is the schematic diagram (when montant goes to horizontal level) that the utility model differentiates optical illusion.
In figure: 1. base plate, 2. cross bar, 3. montant, 4. rotating shaft, 31. bodies of rod, 32. telescopic heads.
Embodiment
See such as Fig. 1, the utility model comprises rectangle base plate 1, cross bar 2, montant 3, rotating shaft 4.Cross bar 2 is fixed on base plate 1 middle and lower part along the long side direction of base plate 1; Montant 3 is made up of the body of rod 31 and the telescopic head 32 being located at the body of rod 31 head, and the total length of the body of rod 31 and telescopic head 32 equals the length of cross bar 2, and wherein the length of the body of rod 31 is not less than 3/5 of cross bar 2 length.Rotating shaft 4 vertical base plate 1 is located on the perpendicular bisector of cross bar 2, and rotating shaft 4 equals 1/2 of cross bar 2 length to the vertical range of cross bar 2; The body of rod 31 is by rotating shaft 4 and base plate 1 rotation-coupled, and junction equals 1/2 of cross bar 2 length to the distance of the body of rod 31 afterbody.
In Fig. 1, the length of the body of rod 31 is 2/3 of cross bar 2 length, and the total length of telescopic head 32 is 1/3 of cross bar 2 length, and montant 3 is positioned on the perpendicular bisector of cross bar 2, and telescopic head 32 is also all pull-outs upward.Observe the inverse-T-shaped optical illusion pattern that montant 3 is formed with cross bar 2, now montant 3 seems obviously long than cross bar 2.
See Fig. 2, montant 34 is gone to horizontal level around the shaft, now montant 3 is parallel with cross bar 2, and left end and the right-hand member of montant 3 and cross bar 2 align respectively, and their length is equal, differentiates horizontal vertical illusion thus.
Also first can make montant 3 and the inverse-T-shaped optical illusion pattern in cross bar 2 pie graph 1, then regulate the length of telescopic head 32 on (shortening) montant 3, until the length of montant 3 seems equal with the length of cross bar 2.Then montant 34 is gone to horizontal level and carries out length with cross bar 2 and compare around the shaft.Now montant 3 aligns with one end of cross bar 2, and other end montant 3 is shorter than cross bar 2, and the length obtaining montant 3 is less than cross bar 2, differentiates horizontal vertical illusion thus.
