Description

A multifunctional teaching T-square

technical field

The utility model relates to the technical field of teaching supplies, in particular to a multifunctional teaching T-square.

Background technique

T-shaped ruler, also known as T-shaped ruler, is a "T"-shaped ruler with a crosspiece at one end. It is composed of mutually perpendicular ruler heads and ruler bodies. T-shaped rulers are widely used in various design drawings. During use, T-square can be used in conjunction with drawing tools such as set squares and protractors, so that straight lines with various angles can be drawn according to requirements. When scaling a line segment, it must be used in conjunction with a set square, a protractor, etc., and different tool rulers need to be replaced back and forth. Due to the heavy workload in the drawing process, the drawing efficiency is reduced.

Utility model content

The purpose of the utility model is to provide a multifunctional teaching T-square in order to overcome the deficiencies of the prior art.

The utility model is realized through the following technical solutions:

A multifunctional teaching T-square, comprising a horizontal ruler and a vertical ruler, the horizontal ruler and the longitudinal ruler are arranged perpendicularly to each other, a scale line is arranged along the length direction of the horizontal ruler, and a scale line is arranged along the length direction of the longitudinal ruler There are scale marks, and the horizontal ruler is provided with a right-angled triangle through hole, a protractor through hole, and an isosceles triangle through hole from left to right, and a rubber groove for placing an eraser and a rubber groove for placing an eraser are opened on the longitudinal ruler. Pencil slot for pencils.

As a preferred technical solution of the utility model, the rubber groove and the pencil groove are both bar-shaped grooves.

As a preferred technical solution of the utility model, the horizontal ruler and the longitudinal ruler are fixedly connected.

As a preferred technical solution of the utility model, the pencil groove is arranged above the rubber groove.

Compared with the existing technology, the beneficial effect of the utility model is that the utility model has simple structure and reasonable design, does not need to change the drawing ruler back and forth, and improves the drawing efficiency.

Fig. 1 is the structural representation of the utility model.

In the figure: 1-horizontal ruler; 2-longitudinal ruler; 3-right-angled triangle through hole; 4-protractor through hole; 5-isosceles triangle through hole; 6-rubber groove; 7-pencil groove.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Please refer to Fig. 1, Fig. 1 is the structural representation of the utility model.

The multifunctional teaching T-square includes a horizontal ruler 1 and a vertical ruler 2, the horizontal ruler 1 and the longitudinal ruler 2 are arranged perpendicular to each other, and the horizontal ruler 1 and the longitudinal ruler 2 are fixedly connected. A scale line is provided along the length direction of the horizontal ruler 1, and a scale line is provided along the length direction of the longitudinal ruler 2. A right-angled triangle through hole 3 and a protractor are successively opened on the horizontal ruler 1 from left to right. Through hole 4, isosceles triangle through hole 5, on described longitudinal ruler 2, offer the rubber groove 6 that is used to place eraser and the pencil groove 7 that is used to place pencil, described rubber groove 6 and pencil groove 7 are strips Shape groove, described pencil groove 7 is arranged on the top of rubber groove 6.
