Abstract

The utility model relates to a propelling pencil, particularly a propelling pencil with environmental protection function. The propelling pencil with environmental protection function improves a traditional pressing type, uses a screw rod rotating type pushing device to be matched with a special pencil core knife, and overcomes the disadvantages that the pencil cores of previous propelling pencils are easy to break, and the application are greatly limited. The utility model has convenient operation, saves wood, and has a certain environmental protection function, and the pencil cores are not easy to break with wide range of application.

Description

A kind of propelling pencil

The utility model relates to a kind of pencil, especially a kind of propelling pencil with environmental-protection function.

The manufacturing of traditional wooden pencil need expend a large amount of timber usually; also produce the pencil bits during use; be unfavorable for sanitation and hygiene and environmental protection; use and also feel inconvenience very much; especially in modern society; people's study, work rhythm are accelerated, and no matter are the angles from environmental protection and learning efficiency, and its many weak points are all arranged.Propelling pencil in the prior art is the finger pressure push type, though solved environmental issue, and improved service efficiency to a certain extent, but still it is not ideal enough, its major defect is that the pen core that uses is too thin, very easily fracture in the use, and pen core is difficult to adapt to the requirement of writing of various various objectives without sharpening.When for example drawing or tabulating, need thicker lines sometimes, need thinner lines sometimes, the propelling pencil in the prior art is difficult to satisfy the needs of this respect.

The purpose of this utility model is exactly the above-mentioned shortcoming that will overcome prior art, and a kind of timber of both having saved is provided, and pen core is frangibility not again, and uses the wider again propelling pencil with environment protection significance of adaptive surface.

The utility model is achieved through the following technical solutions:

Propelling pencil is made up of nib (1), pencil-lead (2), spring leaf (3), pen core fixed cover (4), pen container (5), screw rod positioning sleeve (6), screw rod (7), positioning sleeve (8), regulating handle (9), pencil-lead cross section (10), pen core connecting hole (11), location annular ring (12), centring ring (13), special-purpose pen core cutter (14), the pen core blade (15) etc. of digging.It is characterized in that: the pencil-lead that is arranged in pen container during use passes nib (1), and is connected with the screw rod propulsion plant by pen core fixed cover (4).The screw rod propulsion plant is made up of pen core fixed cover (4), screw rod positioning sleeve (6), screw rod (7), positioning sleeve (8), regulating handle (9) etc., and is fixed in the pen container (5) by positioning sleeve (8).

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the utility model sectional structure chart;

Fig. 2 is the utility model pencil-lead connecting hole sectional view;

Fig. 3 is a T-shape spring leaf side view of the present utility model;

Fig. 4 is the utility model pen core knife structure figure.

Each part title is identical with the coding of above-mentioned title among the figure.

Pen container (5) is a working of plastics, also can adopt metalwork etc. as required, one end of pen container (5) is a nib, nib (1) can be working of plastics, also can use metalwork, and the central authorities of nib (1) are a pencil-lead hole, the size of neglecting the pencil-lead that is adopted greatly in hole and deciding, one end of pencil-lead (2) has a cross section (10), and pencil-lead one end that has the cross section inserts the pen core connecting hole (11) that is positioned on the pen core fixed cover (4), and also there is a cross section in this hole and matches with the pencil-lead that has the cross section (2).Pen core connecting hole (11) is built-in with a "T"-shaped spring leaf (3) that is used for fixing pencil-lead (2), and spring leaf and pencil-lead direction of insertion are the arc shape of protuberance, and pencil-lead plays fixation when inserting.

Pen core fixed cover (4) fuses with screwed screw rod positioning sleeve (6), and the degree of depth of screwed hole is by the length decision of pencil-lead (2) and pen container (5) and screw rod (7).Regulating handle (9) the inboard screw rod (7) of ining succession, screw rod (7) is rotated into the screwed hole of screw rod positioning sleeve (6), there is screw thread or other shape for lugs of being convenient to turn-knob on the surface of regulating handle (9), the annular ring (12) that the lower end of regulating handle (9) has a diameter and pen container (5) internal diameter to coincide, there is the centring ring (13) of a projection outside of screw rod positioning sleeve (6) and pen core fixed cover (4).Annular ring (12), positioning sleeve (8) and centring ring (13) are positioned at the screw rod propulsion plant in the pen container (5).

Nib (1) is connected with pen container (5) by screw thread, and the junction of regulating handle (9) and pen container (5) has a regulating handle (9) to be enclosed within positioning sleeve (8) in the pen container (5).Pen core cutter (14) is made of plastic casing and sharpener (15), and pen core cutter inlet also is conical, matches with nib, the angle of pen core sharpener is 18～22 degree, the length of sharpener is 6～10 millimeters, is about 1/3rd of pencil sharpener commonly used, and it is fixed in pen core cutter circular cone porch rear side end.During actual the use, the core that only sharpens a pencil, and can not cut to nib (1).

End with pencil-lead band cross section during use passes nib hole, inserts pen core connecting hole (11), turns regulating handle (9) promotion pen core fixed cover and pencil-lead forward, gets final product with the outer pencil-lead of the outstanding nib of special-purpose pen core cutter sharpening.

Propelling pencil described in the utility model, it is simple to have manufacturing technology, and the user makes, and removes Outside the easily-consumed products pencil-lead, but this pen Reusability is saved timber, environment purification, and pen core is stable, Polarization is good, frangibility not, and have the advantages such as applicable surface is wider, be particularly suitable for vast Use among the students in middle and primary schools.
