Ball point pen refill

Abstract

The invention provides a ball point pen refill, and relates to the technical field of ballpoint pens. The ball point pen refill comprises a pen point, a first pen tube, a second pen tube, a fixing mechanism and an adjusting mechanism; the fixing mechanism is used for fixing the second pen tube to the first pen tube, and the end, away from the pen point, of the first pen tube is provided with a silicon oil layer for blocking ink; the second pen tube is used for conveying the ink to the pen point and the silicone oil layer in the first pen tube, and when the ink is conveyed into the first pen tube through the second pen tube, the sealing effect of the silicone oil layer is not damaged, and the technical problem that because the cylindrical ball point pen refill is a disposable product in theprior art, a large amount of resources are wasted, and because the internal structure of the ball point pen refill is destroyed when the ball point pen refill is filled with the ink, the ball point pen refill cannot be used and is wasted are solved; the adjusting mechanism is used for adjusting the circulation or closing between the first pen tube and the pen point; and it is guaranteed that no ink overflows from a gap between the pen point and a ball when the ink is injected into the first pen tube, so that the design is more reasonable.

Description

technical field [0001] The invention relates to the technical field of ballpoint pens, in particular to a ballpoint pen core. Background technique [0002] With the rapid development of our country's science and technology, manufacturing level and new materials, ballpoint pens and ballpoint refills have become representative products for one-time use. At present, the annual output of ballpoint pens in my country is 40 billion pieces. Excluding exports and inventory, the average annual consumption of ballpoint pens is as much as 4.5 billion pieces. Most of the ballpoint pen refills are made of stainless steel or copper. Choose the appropriate tip according to the nature of the ink. , and the refill tube is mostly made of plastic material, such a large consumption causes a lot of waste of state-owned resources. [0003] Although there are also ballpoint refills that can add ink in the prior art, since the cylindrical refill is provided with a silicone oil layer inside the refi...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of ballpoint pen refill, to relieve that the cylindrical refill in the prior art is a disposable product, causing a lot of resources to be wasted, and when the cylindrical refill is filled with ink, the internal structure of the cylindrical refill will be destroyed , resulting in unusable, more wasteful technical problems
