CN201201446Y - Braille geometry template - Google Patents

Abstract

The utility model relates to a braille geometric pattern template, which is composed of a template and a bottom plate. The template is provided with a geometric pattern mold, and its edge is provided with continuous positioning holes. At the same time, put the paper between the template and the bottom plate, and use a braille pen to write continuously along the positioning holes of the graphic mold to draw the corresponding geometric figures, which is easy to operate and easy to use.

Description

Braille geometric figure template

Technical field

The utility model belongs to blind person's schooling apparatus technical field, specifically relates to a kind of blind person's geometric construction template.

Background technology

Draw is that the puzzlement blind child is familiar with a geometric difficult problem always, and existing braille letter stencil, word pen can't be mapped, and the geometric figure template that the normal child uses is not suitable for blind child's use.

Summary of the invention

The purpose of this utility model provides a kind of template of the blind person's of being convenient to drawing geometric figures.

The technical scheme that its technical problem that solves the utility model adopts is: it comprises base plate, base plate top is provided with the template of living and connecting with it, template is provided with the geometric figure mould, figure mould sideline is made up of the locating hole that is coupled to each other, locating hole is an arc, the arc limit that is decided to be the hole interconnects, and makes figure mould edge in wave shape, and the bottom on waveform limit is provided with depression on the base plate.

Because the utility model is made up of template and base plate, template is provided with the geometric figure mould, its edge is provided with continuous locating hole, be decided to be on the base plate of bottom, hole and be provided with depression accordingly, during mapping, paper is put between template and the base plate, start writing continuously along the locating hole of figure mould with the braille pen, can draw corresponding geometric figure, simple to operate, easy to use.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a main body schematic diagram of the present utility model.
