Abstract

The utility model relates to a pen-type gel ink pen with a replaceable pen head, which comprises a pen core head, an ink storing tube, a plastic casing, an inner screw mouth and an outer screw mouth. The pen-type gel ink pen with the replaceable pen head is characterized by further comprising a thin plastic ink-flowing tube. The ink storing tube is a sucking bag type ink storing tube. The pen core head is connected with the sucking bag type ink storing tube through the inner screw mouth. The front end of the pen core head is provided with a small ball. An elastic metal sleeve is arranged outside the sucking bag type ink storing tube. The thin plastic ink-flowing tube is arranged inside the sucking bag type ink storing tube. A layer of soft plastic is covered on the inner screw mouth. When the pen core head is screwed tightly, a main body is tightly matched with the pen core head. Users can replace pen core heads of different models for the pen-type gel ink pen with the replaceable pen head, and ink can be absorbed at any time when ink in the pen-type gel ink pen runs up, thereby saving cost and simultaneously having a environment-friendly function. Further, the pen-type gel ink pen with the replaceable pen head is simple in structure, practical and easy to manufacture.

Description

A kind of pen formula gel ink pen of replaceable nib

Technical field:

The utility model relates to a kind of gel ink pen, especially a kind of pen formula gel ink pen of replaceable nib.

Background technology:

Nib of having only single model of currently marketed gel ink pen.Gel ink pen uses extensively, and output is big, and the small column on the pen core head drops when printing ink is unspent easily sometimes, has caused many inconvenience, after printing ink uses up pen core is thrown away, and has not only wasted but also is unfavorable for environmental protection.

Summary of the invention:

The purpose of the utility model just is the deficiency to above-mentioned technology, and a kind of pen formula gel ink pen of replaceable nib is provided.

The technical scheme of the utility model is:

A kind of pen formula gel ink pen of replaceable nib, it comprises pen core head, Chu Moguan, plastic casing, inside and outside screw socket also comprises the creeping plastic straw; Chu Moguan is for inhaling the capsule formula; Pen core head is connected through interior screw socket with suction capsule formula storage China ink pipe, and wherein the pen core head front end is provided with a little ball; Outside inhaling capsule formula storage China ink pipe, an elastic metallic cover is set; The creeping plastic straw places inhales capsule formula storage China ink pipe inside.Interior screw socket covers one deck flexible plastic outward, and when tightening pen core head, main body and pen core head are in tight fit, at the pen core head front end the one plastics cap for brush is set.

The practical function of the utility model is:

1. the utility model adopts pen formula blotting pen core, makes people can change the nib of different model according to the thickness of writing font, and when not having China ink, can suck at any time, has practiced thrift cost, also environment has been played very big protective effect simultaneously;

2. the utility model is simple in structure, practical and manufacturing easily.

Description of drawings:

Further the utility model is described below in conjunction with accompanying drawing and case study on implementation.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the agent structure sketch map.

Fig. 3 is a pen core head.

Fig. 4 is a plastic casing.

Among the figure, 1 is pen core head, and 2 for inhaling capsule formula storage China ink pipe, and 3 is the creeping plastic straw, and 4 is the elastic metallic cover, and 5 is plastic casing, and 6 is little ball, and 7 is interior screw socket, and 71 is nut, and 72 is screw, and 8 is outer screw socket, and 81 is nut, and 82 is screw.

The specific embodiment:

Like the pen formula gel ink pen of Fig. 1, Fig. 2, Fig. 3, a kind of replaceable nib shown in Figure 4, it comprises pen core head, Chu Moguan, and plastic casing, inside and outside screw socket also comprises the creeping plastic straw; Chu Moguan is for inhaling the capsule formula; Pen core head is connected through interior screw socket with suction capsule formula storage China ink pipe, and wherein the pen core head front end is provided with a little ball; Outside inhaling capsule formula storage China ink pipe, an elastic metallic cover is set; The creeping plastic straw places inhales capsule formula storage China ink pipe inside.Interior screw socket covers one deck flexible plastic outward, and when tightening pen core head, main body and pen core head are in tight fit.

During use: after printing ink uses up, pen core head 1 is turned on, plastic casing 4 is backed out, main body is stretched in the ink bottle, extruding elastic metallic cover 4 after negative pressure sucks printing ink, is screwed on pen core head 1 and plastic casing 4 again, thereby continues to use; When the little ball on the pen core head drops, pen core head 1 is backed out, change another pen core head and get final product; When needs are write the font of different thicknesses, pen core head 1 to be backed out, the pen core head of changing different model just can meet the demands.

Basic principle and the principal character and the advantage of the utility model of more than describing.The utility model does not receive the restriction of above-mentioned case study on implementation; The above-mentioned principle that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all will fall in the scope of the utility model of requirement.
