Abstract

The invention discloses a safe cartridge, which belongs to the stationery. The safe cartridge mainly solves the problem that the traditional cartridge is likely to damage. The safe cartridge structurally comprises a cartridge body, wherein the outer edge of the pen point of the cartridge body is provided with an extruded lifting lug; a casing pipe is a hollow pipe of which the internal diameter is more than the external diameter of the cartridge body; one end of the casing pipe is a sealing end; the other end of the casing pipe is an open end; one end of a spring is sheathed with the upper end of the cartridge body; and the other end of the spring is sheathed with the open end of the casing pipe. The safe cartridge disclosed by the invention has the advantages of simple structure, safety and convenience in use and easiness in operation, the cartridge discarding phenomenon can be effectively reduced and avoided, and the waste is reduced.

Description

A kind of safe pen core

Technical field

The present invention relates to a kind of stationery, specifically is a kind of safe pen core.

Background technology

Signature pen, ball pen all are the writing implements that people generally use, it writes round and smooth and flexible with it, quite smooth and be subject to liking of people, but because the pen core of above two kinds of pens mostly is disposable, the nib place is comparatively fragile, and when pen core dropped on the ground or bumps with comparatively hard object, nib was easy to impaired, thereby cause whole pen to scrap, impact is used.

Summary of the invention

The object of the present invention is to provide a kind of safe pen core, this pen core has the function of buffering when being subject to clashing into.

The present invention solves the technical scheme that its technical problem takes: a kind of safe pen core, its structure comprises the pen core body, outward flange at the nib place of pen core body is provided with the hanger of projection, sleeve pipe is that internal diameter is greater than the hollow pipe of this body diameter of pen core, one end of sleeve pipe is blind end, the other end is the open end, an end of spring and the socket of the upper end of pen core body, the open end socket of the other end and sleeve pipe.

The invention has the beneficial effects as follows: during use, pen core is passed spring and insert in the sleeve pipe, this moment, spring one end withstood on the hanger place of pen core, the other end withstands on the edge of sleeve pipe, to be clashed at nib or hard thing when conflicting, can rely on the elastic force of spring to cushion, thereby protection pen core and nib are not damaged; The present invention is simple in structure, uses safety, convenient, easy to operate, can effectively reduce and avoid the phenomenon of scrapping of pen core, cuts the waste.

Description of drawings

Fig. 1 is structural representation of the present invention.

Among the figure: 1 pen core body, 2 springs, 3 sleeve pipes.

The specific embodiment

As shown in Figure 1.A kind of safe pen core, its structure comprises pen core body 1, outward flange at the nib place of pen core body 1 is provided with the hanger of projection, sleeve pipe 3 is that internal diameter is greater than the hollow pipe of pen core body 1 external diameter, one end of sleeve pipe 3 is blind end, the other end is the open end, an end of spring 2 and the socket of the upper end of pen core body 1, the open end socket of the other end and sleeve pipe 3.

During use, pen core body 1 is passed spring 2 and insert in the sleeve pipe 3, this moment, spring 2 one ends withstood on the hanger place of pen core body 1, the other end withstands on the edge of sleeve pipe 3, to be clashed at nib or hard thing when conflicting, can rely on the elastic force of spring 2 to cushion, thereby protection pen core body 1 and nib are not damaged; The present invention is simple in structure, uses safety, convenient, easy to operate, can effectively reduce and avoid the phenomenon of scrapping of pen core, cuts the waste.

Claims

1. safe pen core, comprise the pen core body, it is characterized in that, outward flange at the nib place of pen core body is provided with the hanger of projection, sleeve pipe be internal diameter greater than the hollow pipe of this body diameter of pen core, an end of sleeve pipe is blind end, the other end is the open end, one end of spring and the socket of the upper end of pen core body, the open end socket of the other end and sleeve pipe.
