Description

Technical Field

[0001] This utility model relates to the technical field of fountain pens, specifically a drop-proof fountain pen. Background Technology

[0002] Fountain pens, as widely used writing instruments, typically have nibs made of metal, offering a unique smoothness and elasticity during writing. However, in daily use, fountain pens are easily dropped from desks or accidentally knocked off due to various unforeseen circumstances. Because the nib is relatively dense, the pen's center of gravity is close to the nib, meaning the nib often hits the ground first upon impact. Once the nib is impacted, it is easily damaged, such as splitting, deformation, or wear. This not only affects the smoothness of writing but can also render the entire pen unusable, causing financial loss and inconvenience to the user. To address the problem of easily damaged fountain pen nibs, various technological attempts have been made. For example, some drop-resistant fountain pens use a weight fixed to the end of the barrel away from the nib, attempting to use the weight to make the barrel land end-to-end, thus protecting the nib. However, because the distance from the desk to the ground is relatively short, and the weight cannot easily adjust its center of gravity during the fall, the protective effect is limited and cannot completely prevent nib damage. Some fountain pens employ automatic nib retraction mechanisms, such as a slot at the rear of the nib that engages with a clip inside the barrel. A telescopic bracket connects to the rear of the slot, and a button and spring control the nib's extension and retraction, ensuring the nib only protrudes from the barrel during writing and retracts automatically otherwise. However, these mechanisms are relatively complex, and components like the button and spring are prone to malfunction after prolonged use, affecting normal operation. Furthermore, features like a sponge layer inside the cap to absorb spilled ink and a light bulb at the rear of the pen, while increasing practicality to some extent, do not provide a comprehensive and effective solution to the core issue of drop protection. In conclusion, developing a drop-resistant fountain pen that more effectively protects the nib, has a reasonable structure, and stable performance is of significant practical importance.

[0003] Application number CN201521019354.7 discloses a drop-resistant fountain pen, comprising a pen cap, a pen neck, a pen refill component, a pen barrel, and a tail cap. The pen refill component is tightly fixed inside the pen barrel by the pen neck. A weight is provided inside the tail cap, and an eccentric structure is provided on the pen barrel. The eccentric structure is composed of multiple annular fins, with adjacent annular fins evenly spaced. From the tail cap to the end, the diameter of the annular fins first increases and then decreases. The cross-section of the eccentric structure through the axis is shaped like an "()". The weight and eccentric structure at the tail ensure that the pen tip is pointing upwards when the pen falls, preventing the pen tip from directly contacting the ground and being damaged. The eccentric structure can also prevent secondary impact to the pen tip caused by rebound. However, the device has shortcomings; it cannot guarantee that the pen tip will not be damaged in any falling scenario regardless of the angle. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a shockproof pen, including a shockproof pen cap assembly 1, and a telescopic adjustable pen body assembly 2 is installed on one side of the inside of the shockproof pen cap assembly 1.

[0026] The anti-drop pen cap assembly 1 includes a protective pen cap 101. The outer wall of the protective pen cap 101 is fixedly provided with anti-slip silicone 102, and a viewing port 104 is fixedly installed on one side of the protective pen cap 101. Anti-drop airbags 103 are fixedly installed around the periphery of several anti-slip silicone 102.

[0027] By installing a drop-proof pen cap component 1 on the device, when using the device, after use, the pen cap can be put on, and the drop-proof pen cap component 1 can provide corresponding limiting protection for the pen tip, thus reducing the chance of accidental damage to the device.

[0028] Anti-slip silicone 102 and anti-drop airbag 103 are evenly distributed around the outer wall of the protective pen cap 101. In the anti-drop pen cap assembly 1, the anti-slip silicone 102 and the anti-drop airbag 103 on the outer wall of the protective pen cap 101 provide dual protection. The anti-slip silicone 102 increases the friction when gripping, preventing the pen from slipping from the hand; the anti-drop airbag 103 absorbs the impact force through its own elastic deformation when the pen is dropped, reducing damage to the pen.

[0029] The telescopic adjustable pen body assembly 2 includes a telescopic pen barrel 201. A rotating screw 202 is fixedly installed at the end of the telescopic pen barrel 201. The rotating screw 202 is threadedly installed inside the threaded storage pen barrel 203, and a pen tip 205 is fixedly installed at the front end of the rotating screw 202. A second anti-drop airbag 204 is fixedly installed around the outer wall of the threaded storage pen barrel 203. In the telescopic adjustable pen body assembly 2, the telescopic pen barrel 201 and the threaded storage pen barrel 203 are connected by the rotating screw 202 to achieve telescopic adjustment, which allows users to adjust the pen body length according to their own needs and improve writing comfort. At the same time, the second anti-drop airbag 204 on the outer wall of the threaded storage pen barrel 203 further enhances the anti-drop performance of the pen body.

[0030] The protective pen cap 101 includes a pen cap tube 1011, an anti-drop silicone ring 1012 is fixedly installed inside the pen cap tube 1011, and a positioning clip 1014 is fixedly installed on one side of the outer wall of the pen cap tube 1011. At the same time, a limiting buckle 1015 is fixedly installed on the inner wall of the pen cap tube 1011 near the outer side. A limiting slot 1013 is opened in the middle of the anti-drop silicone ring 1012. The pen tip 205 is installed inside the limiting slot 1013. The anti-drop silicone ring 1012, the limiting slot 1013 and the limiting buckle 1015 in the protective pen cap 101 cooperate with the assembly buckle ring 2031 of the telescopic adjustable pen body assembly 2 to ensure that the pen cap is firmly connected to the pen body and effectively protect the pen tip 205 when it is dropped.

[0031] An assembly buckle ring 2031 is fixedly installed on the outer wall of one end of the threaded pen barrel 203.

[0032] The assembly buckle 2031 and the limit buckle 1015 mutually limit each other.

[0033] This drop-resistant fountain pen achieves both drop protection and ease of use through the coordinated design of the drop-resistant cap assembly 1 and the telescopic adjustable pen body assembly 2. In the drop-resistant cap assembly 1, the anti-slip silicone 102 on the outer wall of the protective cap 101 and the drop-resistant airbag 103 provide dual protection. The anti-slip silicone 102 increases friction when gripping, preventing the pen from slipping from the hand; the drop-resistant airbag 103 absorbs impact through its elastic deformation when the pen is dropped, reducing damage. In the telescopic adjustable pen body assembly 2, the telescopic pen barrel 201 and the threaded storage pen barrel 203 are connected by a rotating screw 202 to achieve telescopic adjustment, allowing users to adjust the pen length according to their needs and improve writing comfort; simultaneously, the drop-resistant airbag 204 on the outer wall of the threaded storage pen barrel 203 further enhances the pen's drop resistance. Furthermore, the anti-drop silicone ring 1012, limiting slot 1013, and limiting buckle 1015 inside the protective pen cap 101 cooperate with the assembly buckle ring 2031 of the telescopic adjustable pen body assembly 2 to ensure a secure connection between the pen cap and the pen body, effectively protecting the pen tip 205 in case of a fall. In the workflow, preparation work is first done before use. When the pen needs to be used, the user can adjust the pen body length by rotating the telescopic pen lever 201 according to their own grip habits, which drives the rotating screw 202 to rotate within the threaded pen lever 203. After the pen body is adjusted to the appropriate length, the rotation is stopped. At this time, the telescopic adjustable pen body assembly 2 is in a usable state, and the protective pen cap 101 is mutually limited and fixed by the limiting buckle 1015 and the assembly buckle ring 2031 of the threaded pen lever 203.Before use, the user needs to remove the protective pen cap 101 from the telescopic adjustable pen body assembly 2. During the removal process, the pen tip 205 disengages from the limiting slot 1013 of the anti-drop silicone ring 1012. When using the pen, after removing the protective pen cap 101, the user holds the pen body part covered by the anti-slip silicone 102 for writing. The anti-slip silicone 102 provides a good grip and prevents the pen from slipping during writing. If the user needs to adjust the pen body length during writing, it can be adjusted at any time by rotating the telescopic pen lever 201. In the event of an accidental drop, when the pen is accidentally dropped, the anti-drop airbag 103 on the outer wall of the protective pen cap 101 will first contact the ground or other objects, absorbing most of the impact force through compression and deformation, reducing the impact on the pen as a whole. If the pen body part is dropped first... Upon landing, the shock-absorbing airbag 204 on the outer wall of the threaded pen barrel 203 will function, similarly cushioning the impact through elastic deformation, protecting the internal structure of the pen body and the nib 205. Even if the nib 205 is facing down when the pen is dropped, the shock-absorbing silicone ring 1012 and the limiting slot 1013 inside the protective cap 101 can also cushion the impact on the nib 205 to a certain extent, preventing damage to the nib 205 due to collision. After use, it needs to be stored. After use, the protective cap 101 is put back on the telescopic adjustable pen body assembly 2, so that the assembly buckle ring 2031 and the limiting buckle 1015 limit each other. At the same time, the nib 205 is inserted into the limiting slot 1013 of the shock-absorbing silicone ring 1012, completing the storage of the pen and preparing it for the next use.
