Abstract

A drawing board with a T-square comprises a drawing board body, wherein a left chute parallel to the left side of the board surface is arranged on the left side of the board surface of the drawing board body; the upper edge of the board surface of the drawing board body is provided with an upper chute parallel to the upper edge of the board surface; the left sliding chute and the upper sliding chute are respectively provided with a roller with the same structure; a roller in the left sliding chute is fixedly connected with one end of the simple T-square I; a roller in the upper chute is fixedly connected with one end of the simple T-square II; the simple T-square I and the simple T-square II are driven by the roller and respectively and freely move in the left sliding groove and the upper sliding groove, so that the drawing function is simple in structure and high in drawing efficiency.

Description

Drawing board with T-square

Technical Field

The invention belongs to the technical field of drawing boards, and particularly relates to a drawing board with a T-square.

Background

Current drawing board or do not have the T square, or be provided with a T square, if [ CN 202115194U ] patent document, it discloses a drawing board of taking the T square, its structure includes the drawing board body, the right side of drawing board body be equipped with the spout parallel with the side, the spout in be equipped with and follow the gliding slider of spout, upper surface one side of slider is equipped with a pivot parallel with the spout, the one end of T square is through pivot and slider activity hinge joint. The method has the defects that the T-square can only be prevented from being opened, the pattern loss in the drawing process can not be effectively avoided, and the drawing efficiency is low.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide a drawing board with a T-square, wherein the left side of the drawing board is provided with a ruler sliding groove which is parallel to the drawing board arranged above the drawing board, a slidable roller is arranged in the sliding groove, the drawing board and the T-square are combined together, and the T-square can slide at two ends, so that the problem that a pattern is lost due to the fact that the T-square is unstable in the drawing process is avoided, the drawing efficiency is improved, a drawer is very convenient to carry, and the problems that the T-square and the drawing board are inconvenient to carry and the T-square is easy to lose are solved; the drawing device has the characteristics of simple structure and high drawing efficiency.

In order to achieve the purpose, the invention adopts the technical scheme that: a drawing board with a T-square comprises a drawing board body, wherein a left chute parallel to the left side of the board surface is arranged on the left side of the board surface of the drawing board body; the upper edge of the board surface of the drawing board body is provided with an upper chute parallel to the upper edge of the board surface; the left sliding chute and the upper sliding chute are respectively provided with a roller with the same structure; a roller in the left sliding chute is fixedly connected with one end of the simple T-square I; and the roller in the upper sliding groove is fixedly connected with one end of the simple T-square II.

The simple T-square I and the simple T-square II are intersected with the drawing board body and can slide mutually.

The two rollers slide up and down and freely slide left and right respectively to be parallel to the drawing board.

The invention has the beneficial effects that:

the invention has the advantages that the T-square and the drawing board are combined together, and the material of the nail ruler is slightly adjusted. Replace with thin card to reach two rulers and do not influence each other, two rulers can be gone up and down and the horizontal slip, avoid drawing in-process pattern to lose, improved the drawing efficiency of person of drawing to and the person of drawing need not carry two things and convenient, be difficult for losing.

Drawings

Fig. 1 is a schematic structural view of the present invention.

Fig. 2 is a schematic structural diagram of the t-square of the present invention.

In the figure: 1. the drawing board, 2, simple T-square I, 3, simple T-square II, 4, the roller, 5, the left chute, 6, go up the chute.

Detailed Description

The structural and operational principles of the present invention are explained in further detail below with reference to the accompanying drawings and examples.

Referring to fig. 1-2, the simple nail starts from the combination of the drawing board, and the drawing board with the t-square comprises a drawing board body 1, wherein a left chute 5 parallel to the left side of the board surface is arranged on the left side of the drawing board body 1; the upper edge of the surface of the drawing board body 1 is provided with an upper chute 6 parallel to the upper edge of the surface; the left chute 5 and the upper chute 6 are respectively provided with a roller 4 with the same structure; a roller 4 in the left sliding groove 5 is fixedly connected with one end of the simple T-square I2; the roller 4 in the upper chute 6 is fixedly connected with one end of the simple T-square II 3.

The simple T-square I2 and the simple T-square II 3 are intersected with the drawing board body 1 and can slide mutually.

During the use, simple and easy T square 2 can be driven by gyro wheel 4 with simple and easy T square two 3, freely remove in left spout 5 and upper chute 6 respectively, in order to realize the function of drawing, because gyro wheel 4 can restraint simple and easy T square 2, simple and easy T square two 3 can not take off the drawing board body 1, avoid drawing in-process simple and easy T square 2 and simple and easy T square two 3 because the pattern that leads to of taking off loses, it directly takes out the drawing paper from simple and easy T square to change the drawing, put new paper again, the person of facilitating the use changes the drawing.

Claims

1. A drawing board with a T-square comprises a drawing board body (1), wherein a left sliding groove (5) parallel to the left side of the board surface is formed in the left side of the board surface of the drawing board body (1); the drawing board is characterized in that an upper sliding groove (6) parallel to the upper edge of the board surface is arranged on the upper edge of the board surface of the drawing board body (1); the left sliding chute (5) and the upper sliding chute (6) are respectively provided with a roller (4) with the same structure; a roller (4) in the left sliding groove (5) is fixedly connected with one end of the simple T-square I (2); the roller (4) in the upper chute (6) is fixedly connected with one end of the simple T-square II (3).

2. A drawing board with T-square according to claim 1, characterized in that the simple T-square I (2) and the simple T-square II (3) intersect with the drawing board body (1) and can slide with each other.
