Description

Technical Field

[0001] This utility model relates to the field of stationery-related technology, and in particular to a convenient gel pen with a one-button opening mechanism. Background Technology

[0002] A gel pen is short for a ballpoint pen with neutral ink. It is a common writing tool. It can be divided into different types according to the type of pen tip, ink color and structure. Gel pens have the advantages of fountain pens and oil-based ballpoint pens. They have a comfortable writing feel, lower ink viscosity, and appropriate lubricant. The viscosity of the writing medium is between that of fountain pens and oil-based pens, making them smoother than ordinary oil-based pens.

[0003] Existing ballpoint pens require considerable force to open, making them inconvenient to operate. To ensure easy opening and closing and achieve one-button opening, the existing ballpoint pen structure needs to be improved. Utility Model Content

[0004] The present invention aims to overcome the inconvenience of opening the cap when using the pen in the prior art, and provides a convenient one-button cap opening gel pen that is easy to operate.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a one-button opening type convenient gel pen, comprising:

[0006] The pen tube has a slot at its lower end and a clearance hole on its side wall. The clearance hole communicates with the slot, and a pen cap is fastened to the slot at the lower end of the pen tube.

[0007] A pressure rod is placed inside a clearance hole and matches the pen cap.

[0008] This ballpoint pen features a pen tube with a slot at its lower end and a clearance hole on the side wall of the tube. The lower end of the clearance hole communicates with the slot, allowing the pen cap to engage with it. A pressing rod is inserted into the clearance hole, matching the pen cap. When the pen cap is fastened to the pen tube, the pressing rod engages with it. To prevent detachment, pressing the pressing rod pushes the pen cap out, allowing for one-click cap removal and easy operation.

Specifically, a clearance groove is provided at the lower end of the clearance hole, and an ejector block is provided on the side wall of the lower end of the pressing rod, which is placed within the clearance groove. Simultaneously, a locking block is provided at the upper opening of the pen cap. When the pressing rod is pressed down, the ejector block pushes out the locking block, allowing the pen cap to disengage from the locking groove, thus achieving one-click cap removal and opening, making the operation simple and convenient.

[0010] Preferably, the lower surface of the locking block is provided with a locking hole, the side wall of the pressing rod is provided with a locking rod, and the end of the locking rod is provided with a locking block, which is embedded in the locking hole. Specifically, the locking hole on the lower surface of the locking block and the locking rod on the side wall of the pressing block allow the locking block to be inserted into the locking hole when the pen cap is inserted into the slot, and simultaneously, when the pressing block is pressed down, the locking block retracts from the locking hole. This ensures easy removal of the pen cap when the ejector block contacts the locking block, thus simplifying and facilitating one-click cap removal and opening.

[0011] Preferably, the bottom surface of the pressing rod is provided with a guide hole, and the bottom of the clearance hole is provided with a guide rod, which is inserted into the guide hole. Specifically, the guide hole on the bottom surface of the pressing rod and the guide rod on the bottom surface of the clearance hole, with the guide rod sleeved in the guide hole, serve a guiding function and ensure the stability of the pressing rod's movement, thus enabling one-click cap removal and opening during operation.

[0012] Preferably, the guide rod is fitted with a spring, and the top of the spring is connected to the guide rod. Specifically, the spring, with its top connected to the guide rod, ensures that when the pen cap is inserted into the slot, the pressing rod can move upwards, allowing the locking block to be inserted into the locking hole, thus completing the locking of the pen cap and ensuring stable engagement.

[0013] Preferably, the lower surface of the card block is provided with a guide slope. This guide slope facilitates the insertion and removal of the pen cap from the slot, ensuring simple and convenient operation.

[0014] Preferably, a pressing block is connected to the top of the pressing rod. The pressing block, made of rubber, is located at the top of the pressing rod to ensure its effectiveness.

[0015] The beneficial effects of this utility model are: the neutral pen makes the cap removal and cap opening operation simple and convenient, ensuring one-click cap opening. Attached Figure Description
