Description

reusable gel pen

technical field

The utility model belongs to the technical field of gel pens, in particular to a reusable gel pen.

Background technique

The gel pen is a ball-point pen whose viscosity of the writing medium is between water and oil; the gel pen originated in Japan and is a novel writing instrument popular in the world at present. Gel pens have the advantages of both fountain pens and ballpoint pens, with comfortable writing, low ink viscosity, and added substances that are easy to lubricate, so they are smoother than ordinary oily ballpoint pens, and are an upgraded product of oily ballpoint pens. The most important thing about gel pens is gel refills. China uses about 15 billion gel refills every year. Small gel refills are poisonous all over the body. The material of gel refills is polyethylene. This material will last within 200 years. Non-biodegradable, the nib material includes iron, chromium, nickel, lead, copper, tungsten, most of which are heavy metals, and the residue of the gel pen core is butter and ink. The gel refills in the market are disposable, and they are discarded directly after use, which not only pollutes the environment, but also wastes a lot of resources.

Utility model content

The purpose of the utility model is to overcome the defects in the prior art and provide a reusable gel pen with simple and reasonable structural design, simple operation, and the refill of the gel pen can be reused to save resources.

The purpose of this utility model is achieved in that the gel pen includes two parts: a gel pen for writing and a piston for adding ink, the gel pen for writing includes a pen holder and a nib located at the lower end of the pen holder, and the nib includes a hoop , the nib set in the hoop and the ink ball installed on the nib, the piston for adding ink includes a hollow piston rod, the piston rod is provided with a built-in piston rod, and the bottom of the piston rod is provided with a piston A piston handle is provided on the top of the head and the piston rod, and a built-in piston handle is provided on the top of the built-in piston rod.

Preferably, the size of the piston handle is larger than that of the built-in piston handle.

Preferably, the outer diameter of the piston head is equal to the inner diameter of the pen shaft.

Preferably, the pen tip is fitted with a pen cap.

Preferably, the diameter of the pen holder is 11mm.

After the ink is used up, the utility model can use the ink-filling piston to refill ink into the pen holder, thereby realizing the reuse of gel pens. It has reasonable structure design, simple and convenient operation, and can realize the reuse of gel pens and save resources. The advantages.

detailed description

In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation of the utility model is now described with reference to the accompanying drawings, in which the same reference numerals represent the same components. In order to make the drawings concise, each drawing only schematically shows the parts related to the utility model, and they do not represent the actual structure of the product.

As shown in Figures 1, 2, 3, and 4, the utility model is a reusable gel pen, which includes two parts: a gel pen for writing and a piston for adding ink. The pen includes a pen holder 1 and a nib 2 located at the lower end of the pen holder 1. The nib 2 includes a hoop 3, a nib 4 set in the hoop 3 and an ink ball 5 installed on the nib 4. The piston for adding ink includes a hollow structure of the piston rod 6, the inside of the piston rod 6 is provided with a built-in piston rod 7, the bottom of the piston rod 6 is provided with a piston head 8, and the top of the piston rod 6 is provided with a piston handle 9, and the inside of the described piston rod 7 The top is provided with a built-in piston handle 10. The size of the piston handle 9 is greater than that of the built-in piston handle 10 . The outer diameter of the piston head 8 is equal to the inner diameter of the penholder 1 . The pen tip 2 is covered with a pen cap 11 . The diameter of described penholder 1 is 11mm.

The working principle of the utility model is as follows: when the ink in the pen holder 1 is used up, the built-in piston rod 7 is packed into the piston rod 6, and the piston head 8 is installed on the bottom of the piston rod 6, thus forming a piston for adding ink. , and then put the piston for adding ink into the penholder 1, press and hold the piston handle 9 and gently push the piston rod 6, pay attention not to press the built-in piston handle 10 at this time, compress the air in the closed space between the piston rod 6 and the penholder 1, and compress the air The pressure increases, and then the air pushes away the built-in piston rod 7 and discharges the excess air in the closed space between the piston rod 6 and the pen holder 1. When the piston head 8 is close to the butter, the index finger and middle finger clamp the piston handle 9, and the thumb presses the built-in piston handle 10 Pull the piston rod 6 out for a short distance, the purpose is to reduce the air pressure in the closed space between the piston rod 6 and the pen holder 1, at this time, unscrew the nib 2, because the air pressure in the closed space between the piston rod 6 and the pen holder 1 There is tension on the surface of the liquid, so the ink and butter remaining in the pen barrel 1 will not flow out. Insert the pen barrel 1 into the ink bottle, clamp the piston handle 9 with the index finger and middle finger, press the built-in piston handle 10 with the thumb and pull the piston rod 6 , under the effect of atmospheric pressure, ink just enters in the pen holder 1. After filling the ink, you can continue to use the writing. The diameter of penholder 1 of the present utility model is 11mm, can directly use.

The utility model can save a lot of resources by reusing the gel pen, and at the same time has the effect of environmental protection.

The above detailed description is only a specific description of the feasible implementation of the present utility model, and they are not used to limit the protection scope of the present utility model. Any equivalent implementation, change and transformation made without departing from the technical spirit of the present utility model All should be included within the protection scope of the present utility model.
