Description

A kind of syringe pen

Technical field

A kind of pen is the utility model is related to, especially a kind of syringe pen.

Background technology

The history of pen writing is very remote, but pen, which will be write, needs ink, and the ink sac of pen Finite capacity, therefore time for once writing of pen or number of words are limited, it is necessary to fill ink again, and while filling ink need the pen cap Remove, when blotting is also easy to fall the effect of ink, and makes tables and human hand dirty.

Therefore need a kind of blotting convenient, and the pen with larger capacity.

In order to improve writing applicability, more people use ball pen or water-color paintbrush now, still, ball pen and water-color paintbrush Pen core can not be reused after being finished, and can only abandon, and the empty pen core quantity abandoned every year is very big, causes larger waste, It can cause certain environmental pollution.

Therefore need a kind of pen core to reuse, without abandoning, reduce and waste, avoid environmental pollution.

The content of the invention

The defects of the utility model solves existing pen and fills ink inconvenience, and the small writing time of ink sac capacity is short, there is provided A kind of syringe pen, using syringe-type penholder, ink is filled using drawing-in type, fills ink conveniently, and the capacity increase of ink sac, extends once book Write the time.

The pen core that the utility model also solves existing ball pen or water-color paintbrush can not be reused, and cause larger waste And the defects of polluting the environment, there is provided a kind of syringe pen, using syringe-type penholder, repeats suction ink, without abandoning pen core, It will not cause to waste.

Technical solution is used by the utility model solves its technical problem：A kind of syringe pen, including interconnection Nib and penholder, penholder are in syringe-shaped, and penholder includes pen body and the piston rod being inserted in pen body.Penholder is syringe-shaped, is used Ink is filled during suction, fills ink conveniently, and the size of pen body can be larger, so that the volume increase of ink sac, improves ink reservoir volume, prolongs A long writing time；And pen body can be reused, without abandoning, avoid wasting, also avoid causing environmental pollution.

Preferably, pen body is internally provided with pen container, the end position of piston rod insertion pen container is equipped with sealing ring, seals The inner wall of ring and pen container mutually seals.By seal ring seal between piston rod and pen container, sealing ring is multiple tracks, so improves sealing Property, place ink and oozed out from the tail end of pen container.

Preferably, pen container is inner to be coniform, the end of piston rod is coniform.It is coniform to coordinate raising property out of ink, Avoid also leaving more ink in piston rod cutter head pen body.

Preferably, the tail end of pen body is provided with ear mount, the appearance of pen body is provided with scale.Ear mount facilitates piston rod to grasp Make；Syringe pen is also used as other injection ink device, and scale can just show filling ink amount.

Preferably, pen body has the front end that diameter reduces, front end is provided with ladder endoporus, and written interference is inserted into ladder Endoporus is interior and forms sealed connection.Stepped hole is interference fitted with nib, can be played preferably sealing function, be placed connecting portion at this Position leaks.

Preferably, nib and pen body are removable connection, nib is pen nib or ball-pen point or water-color paintbrush pen Head.Removable nib, one easy to suction ink, and is convenient for changing nib, coordinates different nibs to form different books Write effect.

Preferably, nib includes the nib being mutually inserted and written body, written body are inserted into the front end of pen body, nib For syringe needle nib.

Preferably, the end of nib is splay end, the tip of splay end is bulb.

The beneficial effects of the utility model are：Penholder is syringe-shaped, using filling ink during suction, fills black convenient, and pen body Size can be larger, so that the volume increase of ink sac, improves ink reservoir volume, extend a writing time；And pen body can repeat Use, without abandoning, avoid wasting, also avoid causing environmental pollution.

Embodiment

Below by specific embodiment, and with reference to attached drawing, the technical solution of the utility model is made more specifically It is bright.

Embodiment：A kind of syringe pen（Referring to Fig. 1 Fig. 2）, include the nib and penholder of interconnection.

Nib includes nib 1 and written body 2, and nib is inserted into nib in vivo, and the outside of written body is provided with location division 11, The shape of location division is circle, and the diameter of location division is more than the diameter of written body, and one end interference of written body is inserted into penholder Formed and be tightly connected, the inserted terminal of written body is stepped, and location division is in contact with the end of pen body.

Penholder is in syringe-shaped, and penholder includes pen body 4 and the piston rod 7 being inserted in pen body.Pen body is internally provided with pen container 5, the outside diameter of piston rod is less than the diameter of pen container, and the end position of piston rod insertion pen container is equipped with sealing ring 9, sealing ring totally three Road, the inner wall of sealing ring and pen container mutually seal.Pen container is inner to be coniform, and the end of piston rod is coniform.The tail end of pen body Symmetrical two ear mounts 6 are provided with, the appearance of pen body is provided with scale, and 8 diameter of tail end of piston rod is more than the diameter of pen container, living The length of stopper rod is more than the length of pen container.
