Description

Technical Field

[0001] The present application belongs to the technical field of crayons, and more specifically, to a solid paint pen. Background Art

[0002] Industrial crayons are a kind of drawing or marking tool used in industrial production. Industrial crayons have bright colors and can provide clear and eye-catching colors, which are easy to identify and distinguish. In addition, industrial crayons are more wear-resistant than ordinary crayons and can maintain the integrity of colors and marks in various industrial environments. At the same time, industrial crayons have a wide range of applications and can be used to mark the surfaces of various materials such as metal, wood, and plastic. Therefore, industrial crayons are widely used in machinery manufacturing, construction, automobiles and other industries, such as marking parts, marking dimensions, drawing simple patterns, etc. Compared with ordinary crayons, they usually pay more attention to durability and applicability in specific industrial scenarios. Retractable industrial crayons are a type of industrial crayons, and their structural components usually include a pen shell, a pen cap, a pen core, a slide, a handle, a spring and a pen head. The pen shell is the outer shell of the crayon, which is usually made of plastic or metal and is used to protect the pen core and provide a pen-holding part. The pen cap is set on the pen shell to protect the pen tip. The pen core is the core part of the crayon, which is a mixture of pigment and wax, and determines the color and drawing performance of the crayon. The slide seat is located in the pen shell and can slide in the pen shell to adjust the extension length of the pen core. The handle is connected to the slide seat, and the slide seat can be driven to slide in the pen shell by turning the handle, thereby realizing the extension and retraction of the pen core. The spring is located in the pen shell, one end of which is connected to the handle, and the other end is connected to the pen core or the slide seat, which is used to provide the extension and retraction power of the pen core and make the pen core have a certain elasticity when in use. The pen tip is the drawing part of the crayon, which is usually conical or flat. Pen tips of different shapes can be used for different painting needs.

[0003] However, in order to reduce the material cost of the pen cap, the existing retractable industrial crayons often have a cavity on the pen cap for accommodating the pen tip that is much larger than the pen tip. However, since the wax core has a certain volatility, part of the wax on the pen tip may evaporate into the cavity of the pen cap, thereby causing the pen tip to deform and affecting the use effect of the industrial crayons.
