A kind of seven-piece puzzle

Technical field:

The utility model belongs to a kind of educational toy, particularly a kind of seven-piece puzzle.

Background technology:

On the market present, there are a lot of seven-piece puzzles, but most seven-piece puzzles all can only be put some simple figures, its difficulty is generally lower, it is fit to some preschool children's development intelligence, its applicable scope is extensive inadequately, and can make a kind of scope of application relatively extensively and have certain difficulty, the toy of tap intellectual resources is problem demanding prompt solutions more fully.

Summary of the invention:

Goal of the invention: the utility model provides a kind of seven-piece puzzle, its objective is that solution seven-piece puzzle difficulty in the past is on the low side, the problem of its restricted application.

Technical scheme: the utility model is achieved through the following technical solutions:

A kind of seven-piece puzzle, comprise seven plates, it is characterized in that: this seven-piece puzzle is made up of two isosceles right triangles, different right-angled trapezium, a square and the pentagonal plates of three block sizes, and these seven plates are spliced to form literal, letter or symbol mutually; The hypotenuse butt joint back of two isosceles right triangles in this seven-piece puzzle equates with foursquare area; The different right-angled trapezium of three block sizes is divided into minimum right-angled trapezium, medium right-angled trapezium and maximum right-angled trapezium; Wherein the height of minimum right-angled trapezium equates with the foursquare length of side, and the height of medium right-angled trapezium and maximum right-angled trapezium equates; The hypotenuse of medium right-angled trapezium and the length sum of the hypotenuse of the right-angled trapezium of minimum and the equal in length of pentagon longest edge; The hypotenuse length of maximum right-angled trapezium is identical with the length on pentagonal upward base; Pentagonal little minor face and middle minor face meet at right angles.

Advantage and effect:

The utility model provides a kind of seven-piece puzzle, it is made up of seven plates, change formation a plurality of different literal, letter or symbol by the splicing between the plate, if be applied to juvenile's teaching field, it not only rests on and only teaches the category that children debate the knowledge figure, but, make children in the splicing that beats one's brains, learn to debate the knowledge Chinese character again by juvenile's Chinese character different to being spliced to form of different plates; This seven-piece puzzle has certain degree of difficulty, makes it not only can be applied to the juvenile field, and the difficulty that it is moderate also can become the instrument of some adult's spare time amusements; Therefore, the seven-piece puzzle difficulty that this seven-piece puzzle solves in the past is on the low side, the problem of its restricted application; It is cheap, simple for production, easy to carry, and it has recreational, intellectual, scientific, interesting, helps improving people's intellectual level.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is done nearly step explanation:

The utility model provides a kind of seven-piece puzzle, and this seven-piece puzzle is divided into three right-angled trapezium that differ in size, a square, an irregular pentagon and two isosceles right triangles, and they are spliced to form different literal, letter or symbol mutually; The hypotenuse butt joint back of two isosceles right triangles in this seven-piece puzzle equates with foursquare area; Three right-angled trapezium that differ in size are respectively minimum right-angled trapezium 1, medium right-angled trapezium 2 and maximum right-angled trapezium 3; The height of wherein minimum right-angled trapezium 1 equates that with the foursquare length of side height of medium right-angled trapezium 2 and maximum right-angled trapezium 3 equates; Pentagonal five limits are respectively longest edge 4, go up base 5, little minor face 6, middle minor face 7 and long hypotenuse; The hypotenuse of medium right-angled trapezium 2 equates with pentagon longest edge 4 with the length sum of the hypotenuse of minimum right-angled trapezium 1 in this seven-piece puzzle; The hypotenuse length of maximum right-angled trapezium 3 is identical with the pentagonal base 5 of going up; Pentagonal little minor face 6 meets at right angles with middle minor face 7; The trimness of risking literal and the requirement of tightness have been satisfied in the design of shape in this seven-piece puzzle.

This seven-piece puzzle changes literal or the letter that forms as shown in FIG. by the splicing between seven plates, for example: " fourth " word, " worker " word, " on " word, D score word, " X " word, " soil " word, " ten " word, " T " word, " benevolence " word, " Bian " word, " mountain " word, " people " word or " going into " word.It is recreational, intellectual, scientific, interesting that the utility model has, and helps improving people's intellectual level.
