Abstract

The utility model relates to an adjustable and automatic core ejecting pen. The utility model comprises a pen holder, a pen tip, a pen core pipe, a middle sleeve pipe, and a pen cap, wherein the pen core pipe is sleeved inside the middle sleeve pipe, the middle sleeve pipe is sleeved in the pen holder, the upper part of the middle sleeve pip is connected with the upper part of the pen holder through thread, a pen hanging sleeve is combined at the upper part of the pen holder through thread, the pen cap is sleeved at the top part of the pen hanging sleeve, an adjusting button is arranged at the top part of the pen cap, and a pressing plate at the bottom end of the adjusting button is contacted with the top end of the pen core pipe. The adjustable and automatic core ejecting pen has the advantages that the structure is simple, the pen core is uneasy to be broken off, the core ejecting speed is quick, the core ejecting resistance force is small, and the chalk can be taken as the pen core, therefore the adjustable and automatic core ejecting pen can be widely applied to various fields of witting, drawing, and charting, etc.

Description

Adjustable automatic propelling pencil

Technical field

The utility model relates to a kind of stationery, especially relates to a kind of adjustable automatic propelling pencil.

Background technology

At present, the propelling pencil of selling on the market is generally by pen container (shell) and formations such as pen core tube, intermediate casing, and its taper nib directly is threaded with intermediate casing, there are a lot of problems in such structure, as load onto taper when nib as the user, very easily cause between the knockout pipeline of nib and the pen core tube to misplace, thereby the lead for retractable pencil frangibility occurs, not play core, problem such as time core resistance is big.And the knockout length of existing propelling pencil can not in time be controlled, the pencil lead for retractable pencil that fractures when usually causing writing because knockout is long.

In addition, write problems such as unhygienic, frangibility in order to solve chalk, people once attempted having now automatic pencil structure and amplified clamping chalk afterwards, but often bigger because of the pen core tube and the space between the pen container of above-mentioned propelling pencil, and pen core tube is softer and can't realize this design.

Summary of the invention

The utility model purpose provides a kind of adjustable automatic propelling pencil, technical problems such as problem such as existing propelling pencil knockout length can not be controlled to solve, lead for retractable pencil frangibility, the core resistance is big down.

The utility model has also solved existing chalk simultaneously and has write unhygienic, problem such as frangibility when chalk is write.

The utility model is mainly solved the problems of the technologies described above by following technical proposals: it comprises pen container, nib, pen core tube, intermediate casing, the cap for brush, described pen core tube is set in the intermediate casing, and intermediate casing is set in the pen container, the top of its top and pen container is by being threaded, top at pen container has also screwed togather the pen hanging cover, the top of this pen hanging cover is arranged with the cap for brush, and the top of the described cap for brush is provided with adjusting knob nail, and the pressing plate of this adjusting knob nail bottom contacts with the top of pen core tube.

As preferably, described pen container and written one constitute.

As preferably, there is a gap on the pressing plate of described cap for brush bottom and the top of intermediate casing.

As preferably, the top of the described cap for brush is provided with a baffle plate, and there is a gap on the top of this baffle plate and pen hanging cover.

In the utility model, its pen container and nib become one, and intermediate casing extends to the top of pen container, and the major part of pen core tube is entangled, and accurately contraposition between the knockout pipeline of nib and the pen core tube can prevent from like this that pen core from producing to fracture in installation process.In addition, owing to the slit between pen core tube, intermediate casing, the pen container is smaller, the slip that pen core tube can be stable in intermediate casing; and be subjected to the protection of intermediate casing, and intermediate casing is fixed in the pen container, is subjected to the protection of pen container again; after pen container bumped, its pen core can not fracture yet like this.Moreover the cap for brush of the present utility model top is provided with the adjusting knob nail, and this adjusting knob nail can be regulated the distance that pen core tube descends, and then can control the length that pen core exposes on written tip.

On the other hand, after structure of the present utility model is amplified, can also clamping chalk core, allow chalk send core to become a reality automatically like this, write problems such as unhygienic, chalk frangibility thereby solved chalk.

Advantages such as eventually the above the utlity model has rational in infrastructurely, and pen core is not easy to fracture, core is fast down, the core resistance is little down, especially it can be pen core with the chalk.Therefore can be widely used in writing, paint, field such as drawing.

Description of drawings

Below by the specific embodiment and accompanying drawing, the technical solution of the utility model is described in further detail.

Fig. 1 is the structural representation of first kind of preferred implementation of the utility model;

Fig. 2 is the structural representation of second kind of preferred implementation of the utility model;

Fig. 3 is the structural representation of the third preferred implementation of the utility model.

The specific embodiment

Fig. 1 is the structural representation of first kind of preferred implementation of the utility model.It is by pen container 5, formations such as pen core tube 4, intermediate casing 7, the cap for brush 2.Wherein pen core tube 4 is set in the intermediate casing 7, and intermediate casing 7 is set in the pen container 5, and this pen container 5 constitutes with written 10 one.

Spring 8 is equipped with in the bottom of intermediate casing 7, and its top is provided with external screw thread, and this intermediate casing is screwed in the internal thread on the top of pen container 5.The outer surface top of pen container 5 is provided with external screw thread, has screwed togather pen hanging cover 3 on it, and the cap for brush 2 is set in the pen hanging cover 3.

In order to control the stroke of the cap for brush 2, the top of the cap for brush 2 is provided with adjusting knob nail 1, and this adjusting knob is followed closely the pressing plate 11 of 1 bottom and contacted with the top of pen core tube 4, makes the cap for brush 2 unsettled, thereby causes the bottom of the cap for brush 2 and the top of intermediate casing 7 that a gap is arranged.Like this, rotation adjusting knob nail 1 just can be adjusted the distance in above-mentioned gap, and then can control the optimum distance that pen core 6 is released.After adjusting adjusting knob nail 1, press the cap for brush 2 down, pressing plate 11 just promotes pen core tube 4, and simultaneously, pen core tube 4 is released pen core 6; Then, the sandwich device 9 of pen core tube 4 bottoms unclamps, and pen core 6 just exposes from nib.After pressing down certain distance, owing to be subjected to stopping of intermediate casing 7 tops, the cap for brush 2 just can not readvance.So unclamp the cap for brush 2, pen core tube 4 drives sandwich device 9 returns under the effect of spring 8, and the pen core 6 of releasing optimum distance is clamped again.

Fig. 2 is the structural representation of second kind of preferred implementation of the utility model.Different with first kind of preferred implementation is: the top of its cap for brush is provided with a baffle plate 21, and this baffle plate 21 has a gap with the top of pen hanging cover 3.

Fig. 3 is the structural representation of the third preferred implementation of the utility model.As shown in FIG., with pen container 5 in first kind of preferred implementation of the utility model, the enlarged-diameter of associated components such as pen core tube 4, intermediate casing 7 (expand to its pen core tube 4 can by a chalk 61) can realize, but the just automatic propelling of chalk of packing in the pen core tube like this.
