Abstract
The utility model provides a special pen for civil engineering drawing, which belongs to a pen and structurally comprises a pen cap, a pen holder, a pen head, a lead sleeve barrel and a U-shaped pen cap, wherein the end part of the pen cap is movably hinged at the middle part of the pen holder through a pin shaft, a lead is arranged in the lead sleeve barrel, the cross section of the lead is in a rectangular shape, an annular bulge is respectively arranged on the front part of the lead sleeve barrel and the inner side surface of the pen holder, a spring is arranged between the annular bulges, and a clamping sleeve for fixing the lead is also arranged on the pen head. Compared with the prior art, the novel special pen for civil engineering drawing has the characteristics of reasonable design, simple structure, complete function and the like, the drawn engineering drawings have the advantages of high quality, attractive appearance and uniform thickness, the errors are little, in addition, the lead gets out automatically, and the use is very convenient.
Description
Technical field
The utility model relates to a kind of pen, a kind of specifically simple in structure, multiple functional civil engineering drawing special pens.
Background technology
Civil engineering is the general designation of building the science and technology of all kinds of job facilities, relates to various explorations, design, and Graphing of Engineering then is the work that often will do.The wooden pencil of the main employing of prior art mapping, the lead for retractable pencil of pencil is cylindric, line weight inequality in the time of drawing, overall appearance is bad, and influences picture progress, quality and picture person's thinking.And the appearance of pencil is cylindrical, is placed on when the staff is unwanted and causes pencil to drop on certain desktop easily, increases unnecessary trouble in the use.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of civil engineering simple in structure, easy to use drawing special pens is provided.
The technical solution of the utility model realizes in the following manner, this civil engineering drawing special pens, its structure comprises cap, penholder, nib, lead for retractable pencil sleeve, also comprise " U " shape cap for brush, described cap for brush end is by the active penholder middle part that is hinged on of bearing pin, in the above-mentioned lead for retractable pencil sleeve lead for retractable pencil is installed, the cross section of this lead for retractable pencil is a rectangle, on the front portion of described lead for retractable pencil sleeve, penholder medial surface, an annular protrusion is set all, install between this annular protrusion and be provided with spring, also be provided with the fixedly gripping sleeve of lead for retractable pencil on the described nib.
The described cap for brush is around bearing pin 360 degree rotations.
Described gripping sleeve adopts elastic rubber material to make.
Described penholder is shaped as prismatic body.
Described prismatic body is triangular prism, tetrahedron, pentahedron or hexahedron.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that a kind of civil engineering drawing special pens of the present utility model has is simple in structure, easy to use, be skillfully constructed, its penholder adopts prismatic body, make this special pens can not tumble easily, fixation, the cap for brush adopts rotary, made things convenient for the placement of the cap for brush, removed the trouble that needs to place separately the cap for brush when using from, automatically going out plumbous structure setting has made things convenient for the staff to continue to draw, lead for retractable pencil is wide rectangular-shaped, make setting-out even thickness unanimity, institute's engineering drawing of painting is not only attractive in appearance and quality is better.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Mark in the accompanying drawing is represented respectively:
1, cap, 2, penholder, 3, bearing pin, 4, nib, 5, the lead for retractable pencil sleeve, 6, spring, 7, annular protrusion, 8, lead for retractable pencil, 9, gripping sleeve, 10, the cap for brush.
The specific embodiment
Below in conjunction with accompanying drawing civil engineering drawing special pens of the present utility model is done following detailed description the in detail.
As shown in Figure 1, this civil engineering drawing special pens, its structure comprises cap 1, penholder 2, nib 4, lead for retractable pencil sleeve 5, also comprise " U " shape cap for brush 10, the described cap for brush 10 ends are by bearing pin 3 active penholder 2 middle parts that are hinged on, the cap for brush 10 can rotate by 360 degree around bearing pin 3, in the above-mentioned lead for retractable pencil sleeve 5 lead for retractable pencil 8 is installed, the cross section of this lead for retractable pencil 8 is a rectangle, on the front portion of described lead for retractable pencil sleeve 5, penholder 2 medial surfaces, an annular protrusion 7 is set all, install between this annular protrusion 7 and be provided with spring 6, also be provided with the fixedly gripping sleeve 9 of lead for retractable pencil 8 on described written 4.
This gripping sleeve 9 adopts elastic rubber material to make, only need manually push cap 1 when using, cap 1 presses lead for retractable pencil sleeve 5, and lead for retractable pencil sleeve 5 is pushed ahead, under this thrust, the opening part of rubber-like gripping sleeve 9 opens, lead for retractable pencil 8 promotes forward to drop out, after loosing one's grip, under elastic reaction, gripping sleeve 9 is clamped lead for retractable pencil 8 automatically, and the staff uses and gets final product.
Described penholder 2 is shaped as prismatic body, and this prismatic body is triangular prism, tetrahedron, pentahedron or hexahedron, and this structure is arranged so that penholder 2 is difficult for sliding fixation.
