Abstract

The invention relates to a gel pen capable of being recycled. The gel pen comprises a tubular pen core, a pen head and pen oil. The pen head is inserted at one end of the pen core. The other end of the pen core is open. The top portion of a push rod is in a disc shape, and a rubber mat is sleeved on the top portion of the disc. The diameter of the top disc of the push rod is smaller than the inner diameter of the pen core. In addition, a sucking pipe is arranged, the length of the sucking pipe is 4-6 cm, and the inner diameter of the sucking pipe is equal to the outer diameter of the pen core. A circle of annular protrusion is arranged at the portion at one end of the pen head, and the distance between the portion and the pen head is 2-3 cm. After the pen oil in the pen core is used up, a user can take off the pen head and mount the sucking pipe, then the push rod is pulled upwards, and due to movement of the push rod, the inner pressure of a pen core pipe is reduced. Due to effect of outside barometric pressure, the pen oil enters the pen core pipe through the sucking pipe. When the pen oil is full by sucking, the sucking pipe is taken off, the pen head is mounted again for being used continuously, and recycling of the gel pen core is achieved. The gel pen capable of being recycled has the advantages of being reasonable in structure, convenient to use, simple in operation and the like.

Description

A kind of pen core capable of circulation

Technical field

The present invention relates to a kind of writing implement, especially a kind of Neutral ball-point for ball-point pen that can recycle.

Background technology

Key in herein background technology and describe paragraph.Neutral ball-point for ball-point pen is very important a member in stationery, and consumption figure is very big.China is nearly 300,000,000 students at present, and everyone week will 15,000,000,000 with a calculation.The material of refill of gel-ink pen is polystyrene or MPS, and with ageing-resistant, anticorrosive famous, this principle with super-thin plastic bag hard degradation is consistent, is embedded in soil the basic need time of 100 years could degrade voluntarily; Also often contain some heavy metal elements (as nickel, chromium, lead, mercury etc.) in most of nibs and printing ink.After pen core was arbitrarily abandoned, these materials will gather together in soil environment is caused great pollution.Can produce carcinogenic smoke contamination atmosphere when polystyrene burns, especially bioxin has serious harmfulness to the liver of crops and animal etc.The another overall situation killer of Neutral ball-point for ball-point pen after white garbage, old and useless battery! But gel ink pen is easy to use, so welcome by everybody.All gel ink pens problem that all can't solution must not recycle at present.

Summary of the invention

The purpose of this invention is to provide a kind of gel ink pen that can be recycled, be used for solving the gel ink pen consumption large, but not capable of circulation, the problem of contaminated environment.

For achieving the above object, the pen core that the present invention is capable of circulation comprises tubulose pen core, nib and pen oil, pen core one end is assigned nib, and the other end is opening, and a catch bar top is disc-shaped structure, and cover has rubber blanket at the disk top, and the rubber blanket slightly larger in diameter is in the pen core internal diameter; Catch bar top disc diameter is slightly less than the pen core internal diameter; In addition, the length that also has an internal diameter to equal the pen core external diameter is the suction pipe of 4-6 centimetre; Apart from written 2-3 centimeters, one circle annular protrusions is being arranged near a written end.The pen core front end has external screw thread, and nib and suction pipe have internal thread, and there is soft packing ring nib and suction pipe inside, and pen core connects by interference with being connected, by the soft washer sealing of written inside; Pen core and suction pipe are threaded connection, by the soft packing ring realization sealing of suction pipe inside.

After adopting said structure, after the oil consumption in pen core to the greatest extent, the user can take off nib, loads onto suction pipe, then upwards pulls catch bar, due to the penetrator ram motion, the pen core intraductal pressure is reduced.Due to external atmosphere pressure effect, make pen oil enter pen core tube by suction pipe.When pen oil is filled, take off suction pipe, again load onto nib and can continue to use, thereby realize recycling of Neutral ball-point for ball-point pen.In a written side, projection being set is for when drawing pen oil, easily operation.

Advantage of the present invention is rational in infrastructure, and is easy to use, and flexible operation can be by manually solving pen core problem not capable of circulation, the living burden that has reduced environmental pollution and the wasting of resources and alleviated the student.

The specific embodiment

As shown in Figure 1, 2, the present invention's Neutral ball-point for ball-point pen capable of circulation, comprise tubulose pen core 1, nib 6 and printing ink 3 and suction pipe 7, pen core 1 one ends are installed nib 6, and ball is equipped with in written end, and the other end is opening, a catch bar 4 inserts in pen core 1 pipe from opening, catch bar 4 tops are disc-shaped structure, and rubber blanket 5 is arranged on disk, and the rubber blanket diameter is greater than 0.5 millimeter of pen core internal diameter; The diameter of catch bar 4 top disc is less than 0.5 millimeter of the internal diameter of pen core; In addition, the length that also has an internal diameter to equal the pen core external diameter is the suction pipe of 4-6 centimetre; Apart from written 2-3 centimeters, one circle annular protrusions 2 is being arranged near a written end.The pen core front end has external screw thread, and suction pipe has internal thread, and there is soft packing ring nib and suction pipe inside, and pen core connects by interference with being connected, by the soft washer sealing of written inside; Pen core and suction pipe are threaded connection, by the soft packing ring realization sealing of suction pipe inside.
