Description

A chalk set capable of drawing grid lines

Technical Field

The utility model relates to the technical field of stationery, in particular to a chalk set capable of drawing grid lines.

Background technique

Chalk is a widely used tool in the teaching industry, and is generally used for writing on blackboards. Currently, there are mainly two types of chalks: dust-free chalk and water-soluble chalk, and their shapes include truncated cone, cylinder, prism, etc. However, due to structural limitations, the lines of existing chalks when writing or drawing are relatively thin, that is, the same chalk can only draw lines of the same width or fineness. For some occasions where it is necessary to write or draw lines of multiple widths and finenesses at the same time, such as writing Tibetan, the existing chalks cannot meet their needs.

Chinese patent CN202221523691.X, a chalk that can draw lines and write, solves the above problems well, and realizes the function of chalk to draw lines. However, due to the structural limitations of the chalk itself, the marking part cannot be made too long, so there will be a problem that the marking part is quickly used up and not enough for drawing lines, which limits the chalk from drawing lines, or requires another chalk to draw lines, causing waste. On the other hand, when the user holds the chalk to write to the end, a larger section of chalk will be left that cannot be used again, which will also cause waste.

Therefore, those skilled in the art are committed to developing a chalk cover with unrestricted grid lines and reduced waste.

Utility Model Content

In view of the above defects of the prior art, the utility model discloses a chalk cover capable of drawing grid lines, and the technical problem to be solved is to provide a chalk cover capable of drawing grid lines without restriction and reducing waste.

To achieve the above object, the utility model provides a chalk cover capable of drawing grid lines, comprising a hollow cover body, the outer side of the cover body being provided with a drawing line portion, the drawing line portion being a plurality of side covers arranged in a row along the length direction of the cover body.

Preferably, the side cover has a receiving groove for installing chalk. In order to make the grid lines drawn evenly and improve the utilization rate of the chalk, the side cover is arranged perpendicular to the pen cover body.

Preferably, the line drawing portion includes a first grid line portion and a second grid line portion which are arranged opposite to each other.

Preferably, the number of the side sleeves of the first grid-line portion is at least three, and the side sleeves are equidistantly distributed.

Preferably, the number of side sleeves of the second grid-line portion is at least two.

Because some writing requires only two grid lines, and some require multiple grid lines, by providing two grid line parts, different types of grid line drawing requirements can be met. At the same time, the drawing parts are arranged oppositely, and the scribing part is preferably arranged on a narrower surface, which can leave a larger space for the user to hold the chalk, avoid interference with the fingers, and improve the comfort of use.

Preferably, the cross-sectional shape of the pen cover body is circular, quadrilateral, hexagonal or regular polygonal.

Preferably, the cross-sectional shape of the receiving groove is circular, quadrilateral, hexagonal or regular polygonal.

Chalks of different shapes can be selected according to writing needs to achieve writing of grid lines or fonts of different thicknesses. The side cover can be the same shape as the pen cover body or a different shape from the pen cover body. In general, the utility model can manufacture chalk covers of different structures through different combinations, thereby meeting different market needs.

Preferably, the outer side surface of the pen cover body along the length is provided with scales, and through the setting of the scales, the measurement function can also be realized when writing.

Preferably, the protruding height of the side sleeve is 1 to 2 mm. By providing the side sleeve, the height of the marking part directly provided on the chalk is reduced.

Preferably, the length of the pen cover body is 3 to 5 cm.

The above specification settings ensure the comfort of the chalk cover during use, while providing convenient guarantees for packaging, transportation and storage in the early stages of use, and greatly improving the practicality of the product.

The beneficial effects of the utility model are:

Through the structural setting of the utility model, a conventional thicker chalk can be inserted into the pen cover body for writing, and a thinner chalk can be inserted into the side cover of the drawing part for drawing grid lines. In this way, even if the chalk in the side cover is used up, it can be replaced and continued to be used, so that the chalk is no longer limited by the specifications of the chalk itself when drawing grid lines, thereby avoiding waste. In addition, the use of the chalk cover can increase the utilization of the chalk, and even if it is used to be shorter, it can still be used without affecting the grip, further avoiding waste, and improving the user's comfort.
