Description

Gu the method for folding of angle square box

Technical field

The present invention relates to a kind of method for making of vessel, especially a kind of method for making of paper utensil.

Background technology

At present, known paper square box is mostly solid not, and mainly the structure at box angle is firm not.

Summary of the invention

Mostly solid not in order to overcome existing paper square box, mainly the structure at box angle is not firmly not enough, the invention provides the method for folding of a kind of solid angle square box.

The technical solution adopted for the present invention to solve the technical problems is: get square of paper, and trimming mid point line fold line is done in asking of the trimming mid point on adjacent two trimmings, and four trimming mid point line fold lines form a large square; In large square, do a little square, i.e. square at the bottom of box, the foursquare length of side at the bottom of box is box bottom side length fold line, and the limit corresponding to large square is parallel; Extend box bottom side length fold line to trimming intersection point, its prolongation is the positive broken line of extended line; The positive broken line of extended line and the large foursquare length of side intersect at the first intersection point; Point positive broken line of extended line such as the first intersection point is the short positive broken line of the first extended line near trimming part, in the middle part of paper, be divided into the short positive broken line of the second extended line; The large foursquare length of side is divided into three parts by two the first intersection points in the large square length of side, and middle part is fold line in the middle part of the large length of side; The part at two ends is the positive broken line in large length of side end; Between two trimming intersection points that same paper angular vertex is nearest, do the positive broken line of trimming intersection point line, and between paper angular vertex, form paper angle triangle; Do perpendicular line fold line by the summit of square corner at the bottom of box to nearest trimming, intersect at trimming mid point; Do the first angular bisector fold line at the angle of perpendicular line fold line and the positive broken line of extended line, intersect at the second intersection point with the positive broken line in end; The acute angle formed at the positive broken line of extended line and trimming does the second angular bisector fold line, intersects at the second intersection point with the positive broken line in end; The positive broken line in large length of side end is divided into two parts by the second intersection point, is the short positive broken line of large length of side trimming part near trimming intermediate section, in the middle part of paper, be divided into the short positive broken line of part in large length of side paper; Between nearest two the second intersection points, do the second intersection point line fold line, intersect at the 3rd intersection point with perpendicular line fold line; Perpendicular line fold line is divided into two parts by the 3rd intersection point, is the short positive broken line of perpendicular line near trimming intermediate section, in the middle part of paper, be divided into the short fold line of perpendicular line;

According to the positive broken line of extended line, the first angular bisector fold line, the second angular bisector fold line, the second intersection point line fold line and the large short positive folding line of length of side trimming part, the short positive broken line of perpendicular line overlaps with the short fold line of perpendicular line and is affixed, second intersection point line fold line overlaps with fold line in the middle part of the short positive broken line of part, the large length of side in large length of side paper and is affixed as fold line in the middle part of the large length of side that overlaps, and forms square box preliminary configuration;

According to fold line and the positive folding line of trimming intersection point line in the middle part of the large length of side of coincidence, intersection point line positive broken line in trimming overlaps with box bottom side length fold line and is affixed, and at the bottom of paper angle triangle and box, square is affixed, Gu angle square box completes.

The invention has the beneficial effects as follows, design is unique, novel structure; Draw materials conveniently, make easily; Handsome in appearance, durable.
