Description

The propelling pencil of auto-feed pencil lead

Technical field

The utility model relates to a kind of propelling pencils of auto-feed pencil lead, belong to novel office table separation.

Background technique

Currently, common propelling pencil can only fill one-pen lead when in use, pencil lead is needed replacing after being finished, influences to learn Efficiency.In addition, pencil lead quality is different in the market, propelling pencil user is mostly students in middle and primary schools, regular contact pencil lead, pencil lead Powder can stick to your hands, and cleaning or wiping not in time will affect health.This product uses certainly for student or office worker When dynamic pencil is largely write, change-fountain pen lead is inconvenient dangerous and designs.A kind of propelling pencil for not needing to change label manually often out.

Utility model content

The technical problem to be solved by the utility model is to overcoming the deficiencies of the prior art and provide a kind of auto-feed pen The propelling pencil of lead, it can accommodate more pencil leads simultaneously, and pencil lead auto-feed can be made to enter working position.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is: a kind of automatic lead of auto-feed pencil lead Pen, including inner cylinder, and the pen core being supported in inner cylinder, the region between the pen core and inner cylinder is pencil lead rest area, described Pen core includes the workspace of lower part and the supporting region on top, and close to pen tip, the supporting region is described close to tail for the workspace The supporting region side fluting for making the pencil lead feeding in pencil lead rest area fall into supporting region is provided on the supporting region of pen core, it is described interior The bottom of cylinder is set as the tilting baffle of spiral, and the bottom position of the tilting baffle of spiral extends to the bottom of supporting region side fluting, Also, the tilting baffle of spiral is tilted from the edge of the inner cylinder to pen core direction.

Further, the workspace of the pen core and the junction of supporting region are arc transition connection structure so that pencil lead from Supporting region side fluting slides into workspace after entering automatically.

Further, the supporting region of the pen core is 1.5 times of the cylindrical drum that diameter is the vertical diameter of one-pen, the supporting region Side fluting is located at the side wall of cylindrical drum, and the width of the supporting region side fluting is also 1.5 times of the vertical diameter of one-pen.

Further, the workspace of the pen core is connected with pencil lead telescopic device.

Further, it is equipped in the tail end of the pen core for pressing pen core so that the pressure head that pencil lead is constantly sent out.

Further, the supporting region of the pen core extends upwardly to a tail from the workspace of pen core.

Further, this propelling pencil further includes outer cylinder, and the inner cylinder is supported in the outer cylinder, and the diameter of the outer cylinder is 8-15mm, the diameter of the inner cylinder are 6-9mm.

Further, the spiral tail cap of rotatable dismounting is installed in the tail portion of the inner cylinder.

Further, the outer cylinder and inner cylinder utilize transparent plastic material, using the plastic shaping for squeezing out or being blow molded Technique forms.

After above-mentioned technical proposal, the utility model have the utility model has the advantages that

1) the utility model adds a pen core in the inside of inner cylinder, by be arranged in pen core side supporting region side slot with Inner cylinder connection, the bottom of inner cylinder are set as the tilting baffle of spiral, prevent pencil lead from freely falling, and play the guiding role to pencil lead movement, So that the pencil lead being placed in pencil lead rest area automatically falls into pen core, obtain after the pencil lead in pen core is finished, pencil lead is certainly The effect of dynamic feeding, and inner cylinder has the function of a certain amount of pencil lead of storage, plays and saves the time, improves efficiency, reduction pair The effect of health infringement；This product meets the requirement that student attends class using propelling pencil, saves the time for changing lead, improves Learn office efficiency, substantially reduces the harm to body；

2) bottom of the inner cylinder of the utility model is set as the tilting baffle of spiral, so that being every time finished the pencil lead in pen core Afterwards, the pencil lead above the tilting baffle of spiral will start automatic toward pen core feeding, since the tilting baffle of spiral is that screw type is tilting , so the height of every pencil lead bottom end is all different, fed successively to pen core from low to high from the bottom of baffle；

3) it is connected between the workspace and supporting region of pen core with arc transition, opens pencil lead by the supporting region side of supporting region It can be passed through when slot, pencil lead is facilitated to enter the center of pen core, be conducive to the release of pencil lead；

4) diameter of the supporting region of the pen core of the utility model is about 1.5 times of the vertical diameter of one-pen, also, is held in pen core Carrying the supporting region side fluting on area's side wall is the through slot that the width opened from top to bottom is 1.5 times of pencil lead diameter, so that every time only The risk that pencil lead falls parallel in feeding can be allowed to avoid by one-pen lead；

5) by rotating the spiral tail cap for a tail of dismantling, a large amount of pencil lead is disposably put into the pen between pen core and inner cylinder Lead rest area, for realizing later auto-feed.
