CN202345104U - Novel refill - Google Patents

Abstract

The utility model discloses a novel refill which comprises an ink pipe and a nib. The upper end of the ink pipe is in a spiral shape, the lower end of the ink pipe is a straight pipe, a spring is arranged at the lower end of the ink pipe, and the spring clamps the junction position of the spiral-shape portion and the straight pipe portion. According to the novel refill, the ink pipe is provided with the spiral-shape portion, the capacity is added by more than two times without change of the existing pen case, in view of the service life of the nib, the diameter of the spiral-shape portion is no more than 1cm, therefore the service life of the refill is almost ends when ink is used up, and resources are fully used.

Description

A kind of novel pen core

Technical field

The utility model relates to a kind of pen core, relates in particular to a kind of durable pen core.

Background technology

For ball pen or water-color paintbrush, when using up a ball pen, the few really can not change-fountain pen of a change-fountain pen core shell, so resource, every day in waste, reducing, this is undoubtedly.How to cut the waste low-carbon (LC) life the becoming task of top priority of response country.

Summary of the invention

To above-mentioned technological deficiency, the utility model proposes a kind of novel pen core.

In order to solve the problems of the technologies described above, the technical scheme of the utility model is following:

A kind of novel pen core comprises ink barrel and nib, and twist, the lower end is straight tube on the said ink barrel.

As possibility, said ink barrel lower end is provided with spring, and said spring one end blocks the intersection of said spirality and straight tube.

As possibility, said spirality diameter is no more than 1cm.

The beneficial effect of the utility model is: through ink barrel is made as spirality; When not changing an existing shell, capacity has been increased nearly more than 2 times, consider the problem in service life of nib; The spirality diameter is no more than 1cm; When ink used up, the life-span of pen core also almost finished, and has made full use of resource like this.

Description of drawings

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

The specific embodiment

To combine accompanying drawing and specific embodiment that the utility model is done further explanation below.

As shown in Figure 1, a kind of novel pen core comprises ink barrel 1 and nib 2; Twist, the lower end is straight tube on the said ink barrel, in the cost while of constant shell; Increase the capacity of ink more than 2 times; Said ink barrel 1 lower end can be provided with spring, and said spring one end blocks the intersection of said spirality and straight tube, and such design need not change the manufacturing cost of a telescopic spring shell basically.Because the limited service life of nib 2, impossible unlimited increase ink obtains through a large amount of experimental summaries, when said spirality diameter is no more than 1cm, can make both life-spans reach consistent, like this can utilize resources synthetically.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the utility model protection domain.

Claims (2)

1. a novel pen core comprises ink barrel and nib, it is characterized in that, twist, the lower end is straight tube on the said ink barrel, and said ink barrel lower end is provided with spring, and said spring one end blocks the intersection of said spirality and straight tube.

2. a kind of novel pen core according to claim 1 is characterized in that, said spirality diameter is no more than 1cm.
