Abstract

A pen refill belongs the technical field of pen manufacture, is in H series and B series lead and elongated, has an oval section, and is provided with a refill point at the front end. The pen refill has a simple and reasonable structure, is easy to product and manufacture, and low in cost. The pen refill is matched with a pen for use, and is directly inserted into a pen holder. A refill clamping port and an elastic clamping head can easily clamp and fix the flat (the cross section is oval) refill, so that the sliding phenomenon can be avoided. When the pen refill is used, a pusher pushes the pen refill unceasingly to a needed length, so that writing can be conducted. The operating mode is very simple and fast and convenient. The pen refill can be used to be remained with the length of 0.5-1cm, so that discarding of long pen point and pen refill can be avoided, resources are saved, and the environment is protected. The pen refill has the using range of H series and B series lead, color and water-solubility lead, crayon and chalks used by children and the like.

Description

A kind of pen core

Technical field

The utility model relates to a kind of structure of pen core, relates in particular to a kind of environmental protection, and the structure of health, the lead for retractable pencil that economizes on resources belongs to system pen technology field.

Background technology

The traditional pencil and the pen core of colored pencil all are the cylinder rods generally, are wrapped in the wood pen holder.In the use, need often planing, make pen core expose use, when pencil uses residue 5-6 centimetre when long or when more longer, used just inconveniently, tend to thrown away, waste very big because of the inconvenience quilt that holds a pen.Volume is cut in the use wood chip, lead powder can't reclaim use, also cause very big waste, simultaneously contaminated environment.People protect environment for resource conservation, and are easy to use, and the lettering pen that comprises pencil has been done many researchs; For example number of patent application is a kind of pen of 200920283162.5, and pen core adopts traditional cylinder rod, and pen core places in the chamber of pen; Easy to use, economize on resources the protection environment.Sliding phenomenon appears in the fixing main sandwich mouth and the collet of leaning on of cylinder rod pen core easily.So, be badly in need of on the market wanting the matching used of a kind of and this pen, be easy to fix the pen core of good stability.

The utility model content

The purpose of the utility model is exactly for satisfying the needs in market, a kind of pen core is provided, and this pen core is easy to fix, good stability, and environmental protection, health, utilization rate is high.

The purpose of the utility model is achieved in that a kind of pen core, it is characterized in that said pen core is a lead for retractable pencil, and pen core is a strip, and section ovalize, front end are provided with the pen core point.

Said lead for retractable pencil is H series and B series.

Said ovalize is that a relative edge is a straight flange, and another relative edge is the quadrangle on circular arc limit.

The utility model is simple and reasonable, manufactures easily, and cost is low.This pen core and the patent No. are 200920283162.5 the supporting use of a kind of pen, and pen core is directly inserted in the penholder.Sandwich mouth and collet, the pen core of flat (the section ovalize) that be easy to be fixedly clamped can avoid occurring sliding phenomenon.Promoting propeller on the penholder in use releases the laggard running hand of length that needs endlessly with pen core and writes.Its mode of operation is very simple, efficient and convenient.Can avoid very long nib, pen core to be dropped with pen core with only remaining 0.5 to 1 centimeter to the end, waste resource, contaminated environment.The utility model pen core scope of application has: H series and B series lead for retractable pencil, colored and water-soluble lead for retractable pencil.Also can be the crayon that uses of children and chalk etc.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is an A-A cross-sectional view among Fig. 1;

Fig. 3 is the front end nib structure sketch map of the utility model.

Among the figure: 1 pen core, 2 pen cores point.

The specific embodiment

Pen core 1 is H series and B series lead for retractable pencil.Pen core is the strip flat, and section ovalize (relative edge is a straight flange, and another relative edge is the quadrangle on circular arc limit), front end have pen core point 2.The pen core and the patent No. are 200920283162.5 the supporting use of a kind of pen, pen core are inserted in the penholder the be fixedly clamped pen core of flat (section ovalize) of sandwich mouth and collet.The propeller that promotes on the penholder during use is released pen core gradually.
