Description

A large-capacity ink-absorbing gel pen core with replaceable nibs

technical field

The utility model relates to a gel pen core, in particular to a large-capacity ink-absorbing gel gel pen core with replaceable nibs.

Background technique

The gel pen is a novel writing tool popular in the world at present. The gel pen has the advantages of both the fountain pen and the ballpoint pen. Smooth, it is an upgraded product of the oil-based ballpoint pen. There are three types of nibs: cannonball type, needle tube type and half needle tube, which are made of copper alloy, stainless steel or engineering plastics. The balls are mostly made of stainless steel, hard alloy or aluminum oxide and other materials. The diameter of the ball with medium writing is 0.7 mm, and the diameter of the ball with fine writing is 0.5 mm. There are two types of water storage: fiber bundle water storage and non-fiber bundle water storage. , Commonly used ink colors are red, blue, black, green and so on.

But along with the extensive use of neutral pen, caused present a lot of waste of resources and environmental pollution. Moreover, the nibs of gel pens are mostly imported, which will cause excessive production costs and cause a waste of funds. Most of the existing gel pens are disposable products, which are usually thrown away when they are used up. They have little recycling value, and there are no substitutes for them on the market. The cost of nibs is the most expensive in production, and the disposable gel refills we usually use are often discarded. However, the nib part is still usable, and the cost of nibs is the most expensive in production, so throw it away. Unfortunately, if the nib part is designed to be replaceable, it will help us recycle discarded nibs. It not only saves daily expenses but also protects the environment.

Due to the frequent use of disposable gel pens in today's society, many resources are wasted. The material of the pen core rod, polystyrene or modified polystyrene, has the characteristics of aging resistance and corrosion resistance, and it takes 200 years to degrade by itself; the metal pen tip of the pen core Belonging to heavy metals, it will pollute water, soil, etc., and then affect human health through the food chain; waste pen refills are bringing enormous pressure to the environment, and are likely to become another major environmental killer after white garbage and waste batteries.

Contents of the invention

The purpose of this utility model is to provide a large-capacity ink-absorbing gel pen core with replaceable nibs. The pen core is simple in structure, easy to process, and easy to carry. The finished gel nib is environmentally friendly and recyclable, reducing environmental pollution and waste of resources.

The utility model is achieved in this way, a large-capacity ink-absorbing type neutral pen core with replaceable nibs, which includes a replaceable nib, nib plug, pen cap, pen holder, rubber plug, ink-absorbing piston barrel, and external threaded plastic connecting rod , the rear rubber plug and the internal threaded rotating shaft; it is characterized in that: the head and tail of the nib plug have a cylindrical tube respectively, the replaceable nib is connected with the cylindrical tube at the head of the nib plug, and the cylindrical tube at the tail of the nib plug is connected with the pen holder , the pen cap, the replaceable nib, the nib plug, and the pen barrel are connected through threads, the rubber plug and the ink-absorbing piston barrel are connected to the pen barrel, the internally threaded rotating shaft and the externally threaded plastic connecting rod are connected and inserted into the ink-absorbing piston barrel, and the ink-absorbing piston Rubber stopper after barrel connection.

Further, the replaceable nib can be exchanged for an ordinary gel pen nib that we use and prepare to throw away every day.

Further, the nib plug used to fix the nib is made of ordinary rubber, which is the same size as the nibs produced by various manufacturers, and is connected to the pen holder in an interference fit to prevent ink leakage.

Further, the pen cap has an internal thread to realize the connection with the nib plug and the pen barrel.

Further, the replaceable nib, the nib plug and the pen cap can be assembled into one part, that is, the nib part, which is threadedly connected with the pen barrel.

Further, there is a straw-shaped shaft at the front and back of the pen holder, which is designed as two layers, and a small tube of ink leakage inside is wrapped by a cylinder on the outside. The small tube is respectively connected with the nib plug and the small hole at the front end of the pen holder, and the connection method is an interference fit. , the material is ordinary plastic.

Further, the rubber plug and the rear rubber plug are plugs made of rubber material, and the connection method is interference fit to prevent ink leakage.

Further, the ink-absorbing piston cylinder belongs to the piston structure, which can be inserted into the pen holder, and the ink-absorbing piston cylinder can be disassembled from the pen holder, which is convenient for replacing ink bags of various colors.

Further, the internally threaded rotating shaft and the externally threaded plastic connecting rod are threadedly connected, and the internally threaded rotating shaft moves the externally threaded plastic connecting rod up and down to realize the function of pumping ink. The tip of the externally threaded plastic connecting rod is made of rubber.

Further, both the pen holder and the ink-absorbing piston barrel can store ink, so large-capacity storage is realized.

The effect of the utility model is: simple structure, detachable structure, easy to process and shape, easy to use, when the neutral pen has no ink, just unscrew the part of the nib to realize large-capacity ink absorption, which conforms to the concept of recyclable utilization, It solves the bad habit of throwing away gel pens in daily life, and makes a contribution to building a conservation-oriented society.

Detailed ways

As shown in Figure 1, the utility model works and implements like this, a kind of large-capacity ink-absorbing type neutral pen core with replaceable nib, it comprises replaceable nib 1, nib plug 2, pen cap 3, penholder 4, Rubber plug 5, ink-absorbing piston barrel 6, external thread plastic connecting rod 7, rear rubber plug 8 and internal thread plastic rotating shaft 9; it is characterized in that: the head and tail of the nib plug 2 each have a cylindrical tube, which can be replaced The nib 1 is connected to the cylindrical tube at the head of the nib plug 2, and the cylindrical tube at the tail of the nib plug 2 is connected to the pen barrel 4. The pen cap 3 and the replaceable nib 1, the nib plug 2 are interference fit, and the pen barrel 3 is connected by threads, rubber The plug 5 and the ink-absorbing piston barrel 6 are connected to the pen holder 4, the internally threaded rotating shaft 9 and the externally threaded plastic connecting rod 7 are connected and inserted into the ink-absorbing piston barrel 6, and the ink-absorbing piston barrel 6 is connected to the rear rubber plug 8.

When in use, just unscrew the pen cap 3 to take the nib 1 and the nib plug 3 away together. There is an ink suction tube similar to a straw at the pen holder 4. You only need to extend the ink suction tube at the head of the pen holder 4 into the ink to absorb ink That's it.
