Description

Twenty skilful plate

Technical field

The utility model belongs to jigsaw puzzle game, relates in particular to a kind of twenty skilful plate that can improve observation, the power of imagination, shape analysis and intention logic.

Background technology

A kind of riddle that seven-piece puzzle is comprised of seven blocks of plates.This seven this piece plate can be combined into many figures (more than 1600 kinds), for example: triangle, parallelogram, irregular polygon, player also can be combined into various personages, image, animal, bridge, room, tower etc. it, also some Chinese characters and English alphabet.Its weak point is that the number of patterns of risking is less because plate number is less, and details is not abundant, not image.

Summary of the invention

The purpose of this utility model is to provide a kind of twenty skilful plate, can risk the pattern that details is abundant, vivid, thereby improves the ability of observation, the power of imagination, shape analysis and intention logic.

For achieving the above object, the utility model adopts following technical scheme: a kind of twenty skilful plate, is comprised of the quadrangular plate of circular arc in the right angle pentagonal panel of circular arc in two congruent little isosceles right-angled triangle plates, two congruent large isosceles right-angled triangle plates, two blocks of congruent right-angled trapezium plates, two congruent hexagonal plates with right angle corner, four congruent semicircular plates, four congruent bands and four congruent bands.

Large isosceles right-angled triangle plate, right-angled trapezium plate equate with the area of hexagonal plate with right angle corner, the area of little isosceles right-angled triangle plate is half of large isosceles right triangle area, in band, in the area of the right angle pentagonal panel of circular arc and band, the area of the quadrangular plate of circular arc equates, in four bands, the right angle pentagonal panel of circular arc and the area sum of two semicircular plates equal the area of a large isosceles right-angled triangle plate.

The diameter of semicircular plate is 2/3rds of little isosceles right-angled triangle plate right-angle side length; In band, in the right angle pentagonal panel of circular arc, the length that has two limits is half of little isosceles right triangle right-angle side length, and the length that separately has two limits is the sixth of little isosceles right triangle right-angle side length, and in it, the radian of circular arc is 90 degree; In band, in the quadrangular plate of circular arc, the length on its base and little isosceles right triangle right-angle side are equal in length, and the angle on another two straight flanges and base is 45 degree, and in it, the radian of circular arc is 90 degree.

The upper base edge lengths of right-angled trapezium plate is 1/3rd of bottom length, and it is highly two times of upper base edge lengths.

Adopt twenty skilful plate of technique scheme, comprise 12 the interior arc plate of band and semicircular plates that area is less, therefore the pattern kind of being risked by it changes more, details is abundanter, more vivid, contributes to improve the ability of picture mosaic person's observation, the power of imagination, shape analysis and intention logic.Be more suitable for adult after the leisure, use one's hands and brains, temper finger, cultivate one's taste.

The specific embodiment

Twenty skilful plate as shown in Figure 1, is comprised of 19,20, two congruent quadrangular plate 5,6,7,8 with circular arc in 11,12,13,14 and four congruent bands of right angle pentagonal panel of circular arc in 9,10,15,16, four congruent bands of 17,18, four congruent semicircular plates of hexagonal plate of right angle corner of 2,3, two blocks of congruent right-angled trapezium plates of 1,4, two congruent large isosceles right-angled triangle plates of two congruent little isosceles right-angled triangle plates.

As shown in Figure 2, large isosceles right-angled triangle plate 2, right-angled trapezium plate 19 equate with the area of hexagonal plate 17 with right angle corner, the area of little isosceles right-angled triangle plate 1 is half of large isosceles right triangle 2 areas, in band, in the area of the right angle pentagonal panel 11 of circular arc and band, the area of the quadrangular plate 5 of circular arc equates, in four bands, the area sum of 11,12,13,14 and two semicircular plates 15,16 of right angle pentagonal panel of circular arc equals the area of a large isosceles right-angled triangle plate 2.The diameter of semicircular plate 9 is 2/3rds of little isosceles right-angled triangle plate 1 right-angle side length; In band, in the right angle pentagonal panel 11 of circular arc, the length that has two limits is half of little isosceles right triangle 1 right-angle side length, and the length that separately has two limits is the sixth of little isosceles right triangle 1 right-angle side length, and in it, the radian of circular arc is 90 degree; In band, in the quadrangular plate 6 of circular arc, the length on its base and little isosceles right triangle 1 right-angle side are equal in length, and the angle on another two straight flanges and base is 45 degree, and in it, the radian of circular arc is 90 degree.The upper base edge lengths of right-angled trapezium plate 19 is 1/3rd of bottom length, and it is highly two times of upper base edge lengths.

Use the utility model, can risk the patterns such as personage, scenery with hills and waters, flowers and trees, word, implements.As shown in Figure 3, the pattern called after of risking " Bao Chai play butterfly ".As shown in Figure 4, the pattern of risking is " black pigment used by women in ancient times to paint their eyebrows jade is buried flower ".As shown in Figure 5, the implements pattern of risking is " lacquerware ".As shown in Figure 6, the implements pattern of risking is " cup ".As shown in Figure 7, use the utility model to risk " gold " word.As shown in Figure 8, risk " mound " word.As shown in Figure 9, risk pattern " the negative figure of Longma makes river figure ".As shown in figure 10, risk pattern " turtle is carried book and becomes Eight Diagrams ".As shown in figure 11, risk pattern " the celestial pavilion of the imperial fruit of sweet spring water emperor ".As shown in figure 12, risk pattern " though cucurbit little Zang world ".

According to the size of every block of plate, by little isosceles right-angled triangle plate 1,4, large isosceles right-angled triangle plate 2,3, be called large plate with hexagonal plate 17,18, the right-angled trapezium plate 19,20 of right angle corner, all the other are called platelet.The quantity of platelet is 12, accounts for 3/5 of total quantity; The area occupied of platelet accounts for 2/9 of the gross area.Can find out, because the quantity of platelet is more, pattern kind that twenty skilful plate is risked is many, details is abundanter.It is more suitable for adult after the leisure, uses one's hands and brains, and tempers finger, cultivates one's taste.Contribute to improve the ability of picture mosaic person's observation, the power of imagination, shape analysis and intention logic.
