Abstract

Disclosed is a multipurpose quick lattice drawing board, comprising a rectangle backing board and a t-square. The utility model is characterized in that the upper part edge of the backing board and the left part edge of the backing board are respectively engraved with an evenly dividing ruler whose graduation is made according to a rule of permutation and combination; the lower part edge of the backing board and the right part edge of the backing board are respectively engraved with an ordinary measuring ruler; simultaneously, the two sides of the upper part edge of the backing board are respectively provided with a positioning spring clamp. When the utility model is used, the dependency number of the evenly dividing ruler on the two edges can be found according to the number of required drawing lattices; therefore, any required square lattice can be drawn. The utility model has the advantages that lattices can be drawn regularly with time saving and labor saving; the evenly dividing ruler and the measuring ruler can be used with multipurpose use of one object; the utility model is convenient for popularization for primary and secondary school students for use, low cost.

Description

Multipurpose quick lattice drawing board

The utility model belongs to a kind of school supply and stationery, particularly a kind of many usefulness that are suitable for middle and elementary school student study plate of drawing squares fast.

At present, often need in the students'learning to draw squares with blank sheet of paper, in order to get evenly neat grid, generally be to get hurdle head line earlier, as required blank sheet of paper is converted into required number of squares then, gets grid by creasing with pen again, this method time and effort consuming and folding paper print also inhomogeneous, bring very burden to the student, as need get do not wait grid or statistical graph then can be more difficulty.

The purpose of this utility model is to provide that a kind of many it can be drawn squares the student and become foolproof operation with the plate of drawing squares fast, and is time saving and energy saving and outward appearance is regular, is a kind of very practical student appliance.

The technical solution of the utility model: a kind of many with the plate of drawing squares fast, comprise a rectangle backing plate and a T-square, it is characterized in that be carved with by the permutation and combination rule on limit and left limit above backing plate determines the Equant ruler that scale is made, the common chi of measuring is carved with on limit and right-hand limit below backing plate, and a holding paper spring locating clip respectively is equipped with in the both sides, limit, top of backing plate simultaneously.

Using method of the present utility model: at first paper is rectified and be sandwiched on the backing plate, chi head with T-square is positioned limit, backing plate left side, get hurdle head line then, get needed horizontal line and the crossing grid of vertical line according to the Equant ruler scale of the left side and top again, use Equant ruler to determine to draw squares and the number of finally drawing squares need only be defined as " amassing " when several, two " factors " that gained " amasss " are the reading of the left side and top Equant ruler, as make a call to 15 lattice, then but the on the left side Equant ruler looks for the scale of all " 5 " to mark horizontal line, on top Equant ruler looks for the scale of all " 3 " to mark vertical line, and this is crossing 15 lattice that are gained of line anyhow.

Superiority of the present utility model is: 1, can get required various grids in the utmost point short time, reach the regular purpose of promptly saving time and draw squares; 2, evenly divided and measure chi and all can use, one-object-many-purposes makes students in middle and primary schools from little the beginning effect of T-square is familiar with to some extent and understand simultaneously; 3, with low cost, be convenient in students in middle and primary schools, apply.

Further specify present technique below in conjunction with drawings and Examples.

Accompanying drawing is the planar structure schematic diagram of the related plate of drawing squares of the utility model.

Wherein 1 is backing plate, and 2 are the retainer spring folder, and 3 is T-square, and 4 is the top Equant ruler, and 5 is left side Equant ruler, and 6 for measuring chi.

Embodiment: a kind of many with the plate of drawing squares fast, comprise a rectangle backing plate 1 and a T-square 3, it is characterized in that be carved with by the permutation and combination rule on limit and left limit above backing plate determines the Equant ruler 4 and 5 that scale is made, and the common chi 6 of measuring is carved with on limit and right-hand limit below backing plate.Holding paper retainer spring folder 2 respectively is equipped with in the both sides, limit, top of backing plate simultaneously.

This plate of drawing squares can adopt the plastic material manufacturing.

Claims

A kind of many with the plate of drawing squares fast, comprise a rectangle backing plate and a T-square, it is characterized in that be carved with by the permutation and combination rule on limit and left limit above backing plate determines the Equant ruler that scale is made, the common chi of measuring is carved with on limit and right-hand limit below backing plate, and a holding paper spring locating clip respectively is equipped with in the both sides, limit, top of backing plate simultaneously.
