Description

Chalk sleeve capable of drawing grid lines

Technical Field

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

Background

Chalk is a widely used tool in the teaching industry and is generally used for writing on a blackboard. The existing chalk mainly comprises dust-free chalks and water-soluble chalks, the shapes of the existing chalks comprise cone frustum shapes, cylindrical shapes, prismatic shapes and the like, but the existing chalks are limited by structures, lines of the existing chalks are thinner when writing or drawing, namely, the same chalk only can draw lines with the same width or fineness, and for certain occasions needing to write or draw multiple widths and fineness of lines at the same time, for example, in Tibetan writing, the existing chalks cannot meet the requirements.

The chalk which can be used for drawing grid lines and calligraphy and painting well solves the problems and achieves the function of drawing the grid lines. However, the scribing portion cannot be made too long due to the structural limitation of the chalk itself, so that the scribing portion is quickly used up and is not sufficiently scribed, so that the chalk lines are limited, or another piece of chalk is needed for scribing, and waste is caused. On the other hand, a user holds the chalk to write until the end, a large section of chalk is left and cannot be reused, and waste is caused.

Accordingly, those skilled in the art have focused on developing a chalk sleeve that is not limited in the drawing of grid lines and that reduces wastage.

Disclosure of Invention

In view of the above-mentioned drawbacks of the prior art, the present utility model discloses a chalk sleeve capable of drawing lattice lines, and aims to provide a chalk sleeve which is not limited in lattice line drawing and can reduce waste.

In order to achieve the above purpose, the utility model provides a chalk sleeve capable of drawing lattice lines, which comprises a hollow pen sleeve body, wherein the outer side surface of the pen sleeve body is provided with line drawing parts, and the line drawing parts are a plurality of side sleeves which are arranged in a row along the length direction of the pen sleeve body.

Preferably, the side sleeve is provided with a containing groove for installing chalk, and is perpendicular to the pen sleeve body in order to enable the grid lines to be drawn uniformly and improve the utilization rate of the chalk.

Preferably, the line drawing part comprises a first grid line part and a second grid line part which are oppositely arranged.

Preferably, the number of the side sleeves of the first grid line part is at least three, and the side sleeves are distributed at equal intervals.

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

As only two grid lines are needed for writing and a plurality of grid lines are needed, the line drawing requirements of different types of grid lines can be realized by arranging two grid line parts. Meanwhile, the scribing parts are oppositely arranged, and the scribing parts are preferably arranged on narrower surfaces, so that a larger space is reserved for a user to hold the chalk, interference with fingers is avoided, and the use comfort is improved.

Preferably, the cross section of the pen cap body is round or quadrilateral or hexagonal or regular polygon.

Preferably, the cross section of the accommodating groove is circular or quadrilateral or hexagonal or regular polygon.

Chalk with different shapes can be selected according to writing requirements, so that grid lines or fonts with different thicknesses can be written. The side sleeve can be in the same shape as the pen cap body or in a different shape from the pen cap body, and in general, the chalk cap with different structures can be manufactured through different combinations, so that different market demands can be met.

Preferably, the pen cap body is provided with scales along the outer side surface of the length aspect, and the measuring function can be realized during writing through the arrangement of the scales.

Preferably, the protruding height of the side sleeve is 1-2 mm, and the height of the scribing part directly arranged on the chalk is reduced by arranging the side sleeve.

Preferably, the length of the pen cap body is 3-5 cm.

The above specification sets up the travelling comfort of having guaranteed the chalk cover in the use, has provided convenient guarantee for earlier stage of use such as packing, transportation and depositing simultaneously, has also improved the practicality of product greatly.

The beneficial effects of the utility model are as follows:

through the structure arrangement of the utility model, the conventional thicker chalk can be inserted into the pen cap body for writing, and the thinner chalk can be inserted into the side sleeve of the line drawing part for drawing the grid lines. Therefore, even if the chalk in the side sleeve is used up, the chalk can be replaced and then used continuously, so that the chalk is not limited by the specification of the chalk when the chalk is used up, and waste is avoided. In addition, the chalk sleeve can improve the utilization amount of the chalk, and the chalk can be continuously used even if the chalk sleeve is used to be shorter, so that the holding is not affected, the waste is further avoided, and the use comfort of a user is improved.
