Bullet type smart gel pen

Abstract

The invention relates to the field of stationery, in particular to an intelligent bullet roller ball pen. The intelligent bullet roller ball pen comprises a pen rod, a pen core, a pen point, a top cover, a core cap and a pen cap; the pen core is mounted in the pen rod; the pen point is mounted at the lower end of the pen core; the top cover is mounted at the top of the pen rod; the core cap is mounted at the lower part of the pen rod; the pen cap is sleeved on the pen rod; a PLC, a switch, an alarm and a pressure sensor are mounted on the outer side of the pen rod; the middle part of the inner side of the pen rod is fixedly connected with a hollow cylindrical limiting cylinder; the top of the pen core is fixedly connected with an iron block 1; a coil spring is mounted at the upper part of the inner side of the pen rod, and is mounted between the pen rod and the pen core; and a return spring is connected between an electromagnet 1 and the iron block 1 at the top of the pen core. The intelligent bullet roller ball pen can realize automatic shrinkage of the pen core into the core cap, and effectively reduces the probability of scratching skins and clothes of users by the pen point; and the pen core shrinks into the core cap to prevent the probability of damaging the pen point due to falling of the roller ball pen onto the ground caused by collision.

Description

technical field [0001] The invention relates to the field of stationery, in particular to a bullet-type intelligent gel pen. Background technique [0002] A ball-point pen with a writing medium whose viscosity is between water and oil is called a gel pen; the gel pen originated in Japan and is a novel writing tool that is currently popular in the world. 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. [0003] Nib type: [0004] 1. Bullet type [0005] If you look closely at the tip of this gel pen, we will find that they are like a bullet. During the manufacturing process, we cut a raw rod into a complete nib by metal cutting. The bullet type is suitable for making thicker nibs. Most of the nibs on the market are 0.5MM, and the thickest one can reach...
