Embodiment 1

[0020] A nib 1 and a barrel 3 with an ink chamber 2. The nib 1 includes a nib body 1-1 with a cavity 1-3 and a ball 1-2 arranged at the front end of the nib body 1-1, and there is an ink outlet gap between the ball 1-2 and the nib body 1-1. The rear end of the pen head body 1-1 is connected to the front end of the pen holder 3, and the cavity 1-3 of the pen head body 1-1 communicates with the ink chamber 2 of the pen holder 3. The ink chamber 2 of the penholder 3 is divided into two ink chambers along the length direction of the penholder 3, and the two grinding chambers are the first ink chamber 2-2 and the second ink chamber 2-3, which are respectively installed Available in red and blue ink.

[0021] A piston pushing ink device 4 for pushing ink to move to the front end is arranged in the rear end of the ink chamber. The size of the piston device is not larger than the size of the ink chamber, and the piston can move along the ink chamber. When promoting the first mill c...

Embodiment 2

[0024] The difference between embodiment 2 and embodiment 1 is that the ink pushing device 4 described in embodiment 1 is not provided in embodiment 2. The pen holder 3 in embodiment 2 is made of extrudable plastic tube. When in use, the pen holder 3 is squeezed, so that the inks of different colors therein are moved forward, and different colors are generated during painting. Such as image 3 shown.

Embodiment 3

[0026] 1cm thick cylindrical roller ball, the ball installation shaft passes through the cylindrical roller ball, and is installed on the nib body. The two sides of the cylindrical roller ball are planes. After rotation, the ink will slide out along the horizontal plane and write a 1cm wide line. Such as Figure 4 shown.

Abstract

The invention discloses a ballpoint pen, comprising a pen head (1) and a pen holder (3) with an ink cavity (2); the pen head (1) includes a pen head body (1-1) with a cavity (1-3) and a The ball (1-2) at the front end of the pen head body (1-1) has an ink outlet gap between the ball (1-2) and the pen head body (1-1); the rear end of the pen head body (1-1) and the pen holder (3 ) are connected at the front end, and the cavity (1-3) of the pen body (1-1) communicates with the ink cavity (2) of the pen holder (3); it is characterized in that: the ink chamber (2) of the pen holder (3) is along the The longitudinal direction of (3) is divided into at least two ink chambers, and each ink chamber is filled with ink of different colors. The advantages of the present invention are: the present invention has multiple ink chambers, and each ink chamber is filled with inks of different colors. When in use, the inks of different colors can flow out from the ink outlet gap of the pen head, and color blocks with different color differences can be painted. , especially for painting. The invention has simple structure and convenient use.

Description

technical field [0001] The invention relates to a ball-point pen, in particular a multi-color thick ball-point pen for painting. Background technique [0002] The existing ballpoint pen comprises a nib and a pen holder with an ink cavity; the nib includes a nib body with a cavity and a ball arranged at the front end of the nib body, and an ink outlet gap is arranged between the ball and the nib body; the rear end of the nib body is connected with the front end of the pen holder , the cavity of the pen head body communicates with the ink cavity of the pen holder. But because the penholder is thinner, the amount of ink accommodated in the ink cavity is limited; in addition, generally only one color of ink can be accommodated in the penholder. When drawing, need have the ink of a large amount of different colors, obviously existing ball-point pen can't satisfy the requirement. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the p...
