Abstract

The utility model discloses a three neutral pencil refills, including the ink tube, connecting piece and the nib that connect gradually, be provided with three independent ink passageways in the connecting piece, the arranging of three independent ink passageways is three horn shapes and distributes, and the front end of three independent ink passageways communicates respectively has the ink tube, and the end of three independent ink passageways communicates respectively has the nib. The neutral three-head refill can be matched with the existing pen holder at will to form a three-head pen, the three-head pen can draw different parallel three lines according to the pen holding angle, the line drawing is convenient, and the cost of using the three-head pen is low; and the ink tube of the neutral three-head refill is a neutral ink tube which can be matched with neutral ink respectively to realize three-line three-color.

Description

Neutral three-head refill

Technical Field

The utility model relates to a refill especially relates to a three neutral-head refill.

Background

Under the conditions of art drawing, building drawing and the like, three parallel marking lines with different colors are often required to be drawn, different requirements can be met by the distance between the three marking lines, three pen cores are required to be used, a special three-head pen core is not provided, the design of some three-line pens is that three pen points parallel to each other are arranged side by side according to a special pen type, the three-line pens are complex to manufacture, special pen holder matching is required, the use range of the pen cores is small, the three-line pens cannot be matched with pen holders on the market to use, and the use cost is high.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses a three neutral pencil refills.

The utility model adopts the following technical scheme:

a neutral three-head refill comprises an ink tube, a connecting piece and a pen point which are sequentially connected, wherein three independent ink channels are arranged in the connecting piece, the three independent ink channels are distributed in a triangular shape, the front ends of the three independent ink channels are respectively communicated with the ink tube, and the tail ends of the three independent ink channels are respectively communicated with the pen point.

Preferably, the three independent ink channels are distributed in a regular triangle shape.

Preferably, the front ends of the three independent ink channels are respectively provided with an ink tube limiting ring, the front ends of the three independent ink channels are matched with respective ink tubes, the ink tube limiting rings limit the positions of the ink tubes, and the three independent ink channels are respectively communicated with the respective ink tubes.

Preferably, the tail ends of the three independent ink channels are respectively provided with a pen point limiting step, the tail ends of the three independent ink channels are matched with the pen points, and the pen point limiting steps limit the positions of the pen points inserted into the channels.

Preferably, the three independent ink channels are separated by a barrier.

The utility model has the advantages that: (1) the utility model provides a neutral three-head refill, which can be matched with the existing pen holder at will to form a three-head pen, the three-head pen can draw different parallel three lines according to the pen holding angle, the line drawing is convenient, and the cost of using the three-head pen is low; (2) the ink tube of the neutral three-head refill is a neutral ink tube which can be matched with neutral ink respectively to realize three-line three-color.

FIG. 2 is a partial schematic structural view of the internal structure of the connector of the present invention;

FIG. 3 is a schematic view of a structure of the pen head of the present invention;

in the figure: 1. the ink tube comprises an ink tube 2, a connecting piece 3, a pen point 4, an ink channel 5, an ink tube limiting ring 6, a pen point limiting step 7 and an interlayer.

Detailed Description

The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

example (b): as shown in attached figures 1-3, the neutral three-head refill comprises an ink tube 1, a connecting piece 2 and a pen point 3 which are sequentially connected, wherein three independent ink channels 4 are arranged in the connecting piece, the three independent ink channels are distributed in a regular triangle shape, the front ends of the three independent ink channels are respectively communicated with the ink tube, and the tail ends of the three independent ink channels are respectively communicated with the pen point. The front ends of the three independent ink channels are respectively provided with an ink tube limiting ring 5, the front ends of the three independent ink channels are matched with respective ink tubes, the positions of the ink tubes are limited by the ink tube limiting rings, and the three independent ink channels are respectively communicated with the respective ink tubes. The tail ends of the three independent ink channels are respectively provided with pen point limiting steps 6, the tail ends of the three independent ink channels are matched with respective pen points, and the pen point limiting steps limit the positions of the pen points inserted into the channels. The three independent ink channels are separated by a partition 7.

When the neutral three-head refill is used, the small-diameter pen point is adopted, and the diameter of the pen point is half of that of a conventional refill, so that the neutral double-line refill can be matched with the conventional pen holder at will to form a neutral three-head pen, and the cost of using the neutral three-head pen is low. The ink tube of the neutral three-head refill is a neutral ink tube which can be matched with neutral ink respectively to realize three-line three-color.

The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the scope of the claims.
