Description

Fountain-pen with changable writing core

The utility model relates to Fountain-pen with changable writing core, and (IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or the drawing article group, and the pen technical group field of ink storing tube is arranged in the penholder.Be numbered B43K5/00.

At present, the technology about pen that ink storing tube is arranged in the penholder existing and that once had was all done very fruitful effort to the demand that makes things convenient for function of pen, also once designed many outstanding technical schemes.As declaring of the nineteen ninety-five Decree of Patent Office of China by Ding Shiwei, Granted publication number is CN2215992Y, China Patent No. (ZL) is: No. 95207491.5 utility model title is the utility model patent of " the automatic absorbent pen of hydraulic type ", the technical scheme that is adopted.The pen technical elements that ink storing tube is arranged in penholder is a routine of great value invention, and it has solved the problem of the automatic absorbent function of compression type of pen effectively.But still have some deficits, it also is difficult to solve the inconvenience of suction and the problem that is convenient for changing of suction pen core.

The purpose of this utility model is to provide a kind of Fountain-pen with changable writing core.With inconvenience that solves suction and the problem that is convenient for changing that absorbs water pen core.

The purpose of this utility model is achieved in that this utility model Fountain-pen with changable writing core.Mainly by pen, spiral handspike, piston, water pipe, screw pair, pen core revolve the hole, pen stand revolves the hole and constitutes.The hard plastic material injection moulding processing and manufacturing of its major part water pipe, spiral handspike.The suction pen core of pen can be changed, the head of spiral handspike is installed piston, cover is installed in the water pipe, the head of suction pen core is that pen core revolves the hole, revolving the hole spiral by screw pair and pen stand is connected, it is aperture that pen core revolves the hole, and the ink in the water pipe can not flow out by the liquid tension effect, has so just realized the purpose of this utility model.

There is the technology of the pen of ink storing tube to compare an advantage and improvement in the utility model and the original penholder;

The first, because the utility model has designed pen core and revolved the hole in technical scheme, screw pair and pen stand revolve the hole, can change the suction pen core easily.Thereby the inconvenience of suction and the problem that is convenient for changing of suction pen core just can have more effectively been solved.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the outboard structure schematic diagram of the utility model Fountain-pen with changable writing core;

Fig. 2 is the hydrating structure schematic diagram of the utility model Fountain-pen with changable writing core;

The numbering of parts explanation in the schematic diagram: (1) pen (2) spiral handspike (3) piston (4) water pipe (5) screw pair (6) pen core revolves hole (7) pen stand and revolves the hole

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, the utility model Fountain-pen with changable writing core. Mainly by pen (1), spiral push rod (2), Piston (3), water pipe (4), spiral pair (5), pen core revolve hole (6), pen stand revolves hole (7) Consist of. Its main part water pipe (4), spiral push rod (2) are used the hard plastic material injection molding Make. The suction pen core of pen (1) can be changed, the head installation piston of spiral push rod (2) ( 3), cover is installed in the water pipe (4), and the head of suction pen core is that pen core revolves hole (6), by Spiral pair (5) is revolved hole (7) spiral with pen stand and is connected, and it is aperture that pen core revolves hole (6), water pipe (4) ink in can not flow out by the liquid tension effect, has so just realized of the present utility model Purpose. Thereby the inconvenience of suction and the problem that is convenient for changing of suction pen core just can have been solved.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in use, if the ink in the water pipe (4) has been used up, can change the pen core of the water of substituting the bad for the good, and by screw pair (5) pen core revolved hole (6) and pen stand and revolves hole (7) and be connected and get final product, and is convenient simple and direct.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with the duroplasts, utilize the basic equipment of making a factory, take to assemble in batch to produce by batch, the demand with in the supply study and work so just can realize practical value of the present utility model and economic worth better.
