Description

Technical Field

[0001] This utility model relates to the field of fountain pen technology, specifically to a fountain pen that prevents the cap from accidentally coming off. Background Technology

[0002] A fountain pen is a writing instrument, typically composed of a metal nib, feed, barrel, and cap. The nib is made of metal and contains an ink reservoir. The ink flows out evenly through capillary action, allowing the pen to write or draw on paper. It is widely loved for its smooth writing and clear, beautiful handwriting.

[0003] Existing fountain pen caps are prone to detaching. This unstable adhesion not only forces users to frequently check the cap's position during use but also increases the risk of loss. If the cap accidentally falls off, it may damage the cap itself and even the nib due to impact, affecting writing quality. Furthermore, a lost cap may roll into a hard-to-find corner, causing unnecessary trouble and loss. In important occasions or emergencies, a detached cap can also delay writing progress, affecting work efficiency or academic performance. Therefore, we propose a fountain pen that prevents the cap from accidentally detaching. Utility Model Content

[0004] The purpose of this invention is to provide a fountain pen that prevents the cap from accidentally falling off, thereby solving the problem mentioned in the background art where the cap of existing fountain pens is prone to falling off. This unstable adhesion not only requires users to frequently check whether the cap is securely in place during use, but also increases the risk of loss. Once the cap falls off accidentally, it may damage the cap itself and the pen tip due to impact, affecting the writing effect. At the same time, the lost cap may roll into a hard-to-find corner, causing unnecessary trouble and loss to the user. In addition, in important occasions or emergencies, the falling off of the cap may delay the writing progress and affect work efficiency or academic performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fountain pen to prevent accidental removal of the cap, comprising a pen body, a pen tip fixedly connected to the center of one end of the pen body, a pen cap provided at one end of the pen body, an annular groove provided on one side of the inner wall of the pen cap, mounting cavities provided on one side of the top and bottom of the pen body, springs fixedly connected to the top and bottom of the two mounting cavities, the two springs being arranged symmetrically above and below, a spring plate fixedly connected to one end of each spring, a locking head fixedly connected to one side of the top and bottom of the two spring plates, a groove provided on one side of the top and bottom of the pen body, a pressing block provided inside the two grooves, and a connecting rod fixedly connected to one side of the top and bottom of the two pressing blocks.

[0006] Compared with the prior art, the beneficial effects of this utility model are:

[0007] This fountain pen, designed to prevent accidental cap removal, utilizes a design incorporating a ring-shaped groove, spring, spring plate, locking head, recess, connecting rod, and buttons. The spring's elasticity ensures the locking head on the spring plate engages securely with the ring-shaped groove. This locking mechanism effectively prevents the cap from accidentally falling off, protecting the pen nib from damage, preventing accidental ink spills, and avoiding the inconvenience of a lost cap. Furthermore, the design prioritizes user convenience. By simultaneously pressing two buttons, the connecting rod moves, causing the spring plate to move and allowing the locking head to disengage smoothly from the ring-shaped groove. Users can easily remove the cap from the pen without effort or the need for additional tools, making the operation extremely convenient. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: a fountain pen to prevent accidental removal of the pen cap, including a pen body 1, a pen tip 3 fixedly connected to the center of one end of the pen body 1, a pen cap 2 provided at one end of the pen body 1, an annular groove 4 provided on one side of the inner wall of the pen cap 2, mounting cavities 5 provided on one side of the top and bottom of the pen body 1, springs 6 fixedly connected to the top and bottom of the two mounting cavities 5, the two springs 6 are arranged symmetrically, a spring plate 8 fixedly connected to one end of the spring 6, a locking head 9 fixedly connected to one side of the top and bottom of the two spring plates 8, a groove 10 provided on one side of the top and bottom of the pen body 1, a pressing block 12 provided inside the two grooves 10, and a connecting rod 11 fixedly connected to one side of the top and bottom of the two pressing blocks 12.

[0015] One end of the pen cap 2 has an annular slot 13, and one end of the pen body 1 is fixedly connected to an annular insert 14. A magnetic sheet is fixedly installed on one side of the inner wall of the annular slot 13. One end of the annular insert 14 passes through the interior of the annular slot 13 and is magnetically connected to one side of the magnetic sheet, thus initially fixing the pen cap 2 and the pen body 1. The magnetic attraction allows the pen cap 2 to be stably fitted onto the pen body 1, increasing the firmness of the connection and the convenience of use.

[0016] A vertical groove 7 is provided on one side of the mounting cavity 5. One side of the spring plate 8 extends through the outside of the vertical groove 7 and into the inside of the pen cap 2. The locking head 9 is a hemispherical structure. The top and bottom of the two locking heads 9 extend into the inside of the annular slot 13 and contact the inner wall of the annular slot 13, ensuring that the pen cap 2 can be firmly locked on the pen body 1 to prevent accidental fall-off. The design of the hemispherical locking head 9 makes it easy to engage and disengage from the annular slot 4, while ensuring the stability of the lock.

[0017] The top and bottom of the two buttons 12 extend to the outside of the two grooves 10, and the top and bottom of the two connecting rods 11 extend to the inside of the two grooves 10 and are fixedly connected to the bottom and top of the two buttons 12, respectively, providing a convenient operation to unlock the pen cap 2. The user only needs to press the two buttons 12 at the same time, and the connecting rods 11 will drive the spring plate 8 to move, so that the locking head 9 will disengage from the annular locking groove 4, thereby easily removing the pen cap 2.

[0018] A clip is fixedly connected to one side of the front surface of the pen cap 2 for clipping the pen to a clothing pocket or a book.

[0019] A rubber pad is fixedly connected to one side inside the pen cap 2. One end of the pen tip 3 contacts one side of the rubber pad. When the pen tip 3 is put into the pen cap 2, it can prevent the pen tip 3 from being deformed or damaged by external pressure.

[0020] Working principle: When the pen cap 2 is placed on the pen body 1, the annular insert 14 is first inserted into the annular slot 13 and magnetically connected with the magnetic sheet to achieve initial fixation. Subsequently, the spring 6 uses its elastic properties to push the spring plate 8 to move into the pen cap 2, so that the hemispherical locking head 9 is tightly locked into the annular slot 4. This physical locking mechanism ensures that the pen cap 2 will not fall off on its own when not subjected to external force. Even if the pen is accidentally knocked off or bumped, the pen cap 2 will remain firmly fixed to the pen body 1, effectively preventing problems such as damage to the pen tip 3, ink spillage, or loss of the pen cap 2 caused by the pen cap 2 falling off. When removing the pen cap 2, the user only needs to press the two buttons 12 at the same time. This action will drive the spring plate 8 into the mounting cavity 5 through the connecting rod 11, thereby causing the locking head 9 to disengage from the annular slot 4. Once the locking head 9 is unlocked, the pen cap 2 can be easily removed from the pen body 1 without effort or finding additional tools. This design not only simplifies the operation steps and improves the efficiency of use, but also makes the pen aesthetically pleasing and practical while providing a good user experience.

[0021] In summary, this fountain pen designed to prevent accidental cap removal utilizes a design incorporating an annular groove 4, a spring 6, a spring plate 8, a locking head 9, a recess 10, a connecting rod 11, and a button 12. The spring 6, with its elastic properties, allows the locking head 9 on the spring plate 8 to firmly engage with the annular groove 4. This locking mechanism effectively prevents the cap 2 from accidentally falling off, thus protecting the pen nib 3 from damage and preventing accidental ink spillage. It also avoids the inconvenience caused by the loss of the cap 2. Furthermore, the design prioritizes user convenience. By simultaneously pressing both buttons 12, the connecting rod 11 moves, causing the spring plate 8 to move, allowing the locking head 9 to smoothly disengage from the annular groove 4. Users can then easily remove the cap 2 from the pen body 1 without effort or the need for additional tools, making the operation extremely convenient.
