Description

A drop-resistant fountain pen with triple protection

technical field

The utility model relates to a fountain pen, in particular to an anti-fall fountain pen with triple protection, belonging to the field of office and stationery supplies.

Background technique

As a widely used writing instrument, fountain pens are loved by the public for their smooth, elastic and smooth writing characteristics. However, the fountain pen often falls down due to human carelessness or other accidents during use, thus causing the nib or feed of the fountain pen to be damaged.

Invention patent 201210253015.X discloses a drop-resistant fountain pen, including a nib and a pen holder. A spring is arranged between the bottom and the pen holder, and a pen cover is arranged on the button. When in use, after the hand holds the button, the guard bar at the front is tilted up to expose the nib. After the hand holding the button is removed, the guard bar returns to the initial state due to the reaction of the spring, and the pen tip is effectively protected. However, its structure is slightly complicated, its maintainability is poor, its protection function is single, and it has certain requirements on the strength of the holding hand during the use of the pen, which is easy to make people feel tired.

Utility model content

In order to avoid the deficiencies of the existing technology, the utility model proposes a triple-protection anti-drop pen, which adopts a magnetic steel ring installed at the end of the pen, adds a protective hard shell on the upper part of the nib, and installs a spring on the tongue for shock absorption. , not only prevent or reduce the chance of the pen slipping, but also strengthen the protective measures of the nib and feed; the anti-drop pen has a simple structure, low production cost, and is suitable for mass production.

The technical solution adopted by the utility model to solve the technical problem is: comprising spring, pen feed, protective hard shell, nib, pen holder, magnetic steel ring, pen tail screw cap, pen feed sheath, the pen feed sheath is positioned at the pen holder front end, The feed, nib, protective hard shell, and spring are fixedly connected to the pen barrel through the feed sheath, and the other end of the pen barrel is connected to the pen tail screw cap. The magnetic steel ring is located between the pen barrel and the pen tail screw cap; The spring fits on the feed of the pen, one end rests on the round platform at the end of the feed, and the other end rests on the back of the groove of the boss on the nib; the protective hard shell is located on the top of the nib and parallel to the nib, and the protrusion at the end is in line with the nib The clamping groove of the upper boss cooperates with clamping to form a simply supported structure that protects the hard shell and the nib.

The magnetic steel ring is a ring structure.

The protective hard shell is a thin shell structure that is similar to the nib and smaller than the nib. The end of the protective hard shell is provided with a bump, and the middle part has a small bump.

The diameter of the truncated cone at the end of the tongue is larger than the average diameter of the tongue.

The boss slot on the nib is an inverted L-shaped structure.

Beneficial effect

The utility model proposes a triple-protection anti-fall pen, which adopts a magnetic steel ring at the end of the pen, adds a protective hard shell on the top of the pen tip, and adopts spring shock absorption measures at the pen tongue, which not only prevents or reduces the slipping of the pen probability, and strengthened the protection of the nib and feed. The magnetic steel ring is installed at the tail of the pen through the threaded connection between the tail screw cap and the pen barrel, which can effectively prevent or slow down the slipping of the pen on the desk with metal products. The protective hard shell and the nib are installed in parallel, and there is a certain gap between the protective hard shell and the nib. When the back or inside of the nib is hit, the protective hard shell can be used as a buffer or limit for the nib, thereby effectively protecting the nib. The spring is installed on the feed of the pen. One end of the spring is against the back of the boss slot on the nib, and the other end is against the round platform at the upper end of the feed. When the pen falls and the nib is bumped, the spring is compressed, and the nib and feed Sliding relative to each other effectively reduces the force caused by the collision, slows down the vibration, and protects the nib and feed.

Detailed ways

The present embodiment is a kind of anti-fall fountain pen of triple protection.

Referring to Fig. 1-Fig. 5, the anti-drop fountain pen with triple protection of the utility model consists of a spring 1, a pen feed 2, a protective hard shell 3, a nib 4, a pen holder 5, a magnetic steel ring 6, a pen tail screw cover 7, and a pen feed sheath 8 components, the tongue sheath 8 is connected to the front end of the pen barrel 5, the other end of the pen barrel 5 is connected to the pen tail screw cap 7, the magnetic steel ring 6 is installed between the pen barrel 5 and the pen tail screw cap 7; The card slot is an inverted L-shaped structure, the nib 4 is installed on the front end of the upper part of the feed 2, the spring 1 is set on the feed 2, the diameter of the circular platform at the end of the feed 2 is larger than the average diameter of the feed, and one end of the spring 1 is against the feed On the round platform at the end of 2, the other end of the spring 1 is pushed against the back of the boss slot on the nib 4; the protective hard shell 3 is located on the top of the nib 4 and installed parallel to the nib, and the protrusion at the end of the protective hard shell 3 and the upper protrusion of the nib 4 The table card slot cooperates with clamping to form a simply supported structure of the protective hard shell 3 and the nib 4;

The magnetic steel ring 6 is a ring structure, and the magnetic steel ring 6 is fixed on the tail of the pen through the threaded cooperation between the pen tail screw cover 7 and the pen holder 5; The pen is placed on the desktop, and due to the attraction of the magnetic steel ring 6 at the end of the pen and the metal on the table, the pen will not roll off the desk and protect the pen from damage.

The protective hard shell 3 has a thin shell structure and is similar in shape to the nib 4. In order to avoid affecting writing, the protective hard shell 3 is slightly smaller than the nib 4. The protective hard shell 3 is installed on the back side of the nib 4 and is parallel to the nib to protect the end of the hard shell 3. There is a bump, and there is a small bump in the middle. The bump at the end of the protective hard shell 3 is in interference fit with the boss slot on the nib 4, and the clamping force generated by the interference fit generates frictional self-locking to realize the protection of the hard shell. The connection between the shell 3 and the nib 4, and the middle protrusion make the protective hard shell 3 and the nib 4 form a simply supported structure when the force is applied to enhance the protective effect. The pen accidentally slips from the user's hand, and the nib part hits the ground. When the back of the nib 4 is hit and the falling speed is not high, the deformation elastic force of the protective hard shell 3 is sufficient to withstand the impact force, and can directly play the role of buffer protection ; When the inner side of the nib 4 is collided, the existence of the protective hard shell 3 can limit the deformation of the nib 4, which also plays a protective role; Compress the spring 1 to reduce the impact and protect the pen from damage.
