Abstract
The utility model relates to a drawing pencil composed of a lead and a penholder. The lead shape is that two mutually parallel surfaces are arranged along the axial direction of the lead to form a flat lead. Thereby, when the utility model is in use, uniform thick solid lines on an engineering drawing can be directly drawn without sharpening, and thus drawing quality and work efficiency can be improved. The pencil is a practical drawing pencil during drawing and sketching.
Description
The utility model belongs to a kind of drawing pencil, a kind of drawing pencil that can be used for drawing even heavy line on the engineering drawing.
Existing drawing pencil, its lead for retractable pencil all is columniform, when being used for the heavy line drafting, the drawing personnel must become pancake (from section, generally being rectangle) with lead for retractable pencil by cylindrical reconditioning earlier, could adapt to the heavy line rendering request.But, the lead for retractable pencil reconditioning is become this shape, more bothersome, also pollute drawing easily; In addition, drawing a drawing generally needs repeatedly reconditioning lead for retractable pencil, and the shape of each reconditioning is often inconsistent, thereby causes figure line thickness inequality, influences drawing quality.Therefore, designing a kind of extraordinary core shape drawing pencil that need not the reconditioning lead for retractable pencil, is very necessary.
The purpose of this utility model will provide a kind of exactly and can adapt to the extraordinary core shape drawing pencil of drawing the heavy line requirement.The lead for retractable pencil of this drawing pencil has two surfaces parallel to each other along its axis direction, promptly is a kind of flat lead for retractable pencil, so do not need reconditioning can directly be used for drawing uniform heavy line.
Accompanying drawing 1 is a stereogram of the present utility model.
Accompanying drawing 2 is the cross-sectional view of three kinds of shape lead for retractable pencils in the utility model.
With reference to accompanying drawing 1, accompanying drawing 2, the utility model is made of lead for retractable pencil (1) and penholder (2).Lead for retractable pencil (1) has two surfaces parallel to each other along its axis direction, and the cross section of lead for retractable pencil can be a rectangle, and in this rectangular four jiaos of processing fillets or chamfering, in order to improving lead for retractable pencil intensity; The cross section of lead for retractable pencil also can be by two sections parallel segments and two sections sealing surfaces that circular arc is formed, thereby form a kind of flat lead for retractable pencil of non-cylindrical.Like this, during use, the drawing personnel need not reconditioning as long as lead for retractable pencil is cut out, can be directly used in heavy line and draw, and the trouble of having removed the reconditioning lead for retractable pencil from has improved operating efficiency, and has graphed even, quality of drawing height, advantage such as lead for retractable pencil intensity is big.This kind pencil all can use all kinds of drawing personnel, as engineers and technicians, the student of college etc.When it was used for drawing sketch, effect was also fine, was a kind of drawing pencil of practicality.
The utility model is simple in structure, and manufacturing process is easy, compares with existing cylindrical lead for retractable pencil drawing pencil, and production technology is similar, and production cost does not increase, and can satisfy the requirement of producing technology in enormous quantities.
Claims (3)
1, a kind of drawing pencil that is made of lead for retractable pencil (1), penholder (2) is characterized in that lead for retractable pencil (1) has two surfaces parallel to each other along its axis direction, thereby forms a kind of drawing pencil of flat lead for retractable pencil.
2, a kind of drawing pencil according to claim 1, the cross section that it is characterized in that lead for retractable pencil is a rectangle, and in this rectangular four angles processing fillet or chamfering.
3, a kind of drawing pencil according to claim 1, the cross section that it is characterized in that lead for retractable pencil are by two sections parallel segments and two sections sealing surfaces that circular arc constitutes.
