Description

Technical Field

[0001] This utility model relates to the field of stationery product technology, specifically to a shock-absorbing neutral pen. Background Technology

[0002] A gel pen, also known as a gel ink ballpoint pen, originated in Japan and is a writing instrument that combines the advantages of fountain pens and oil-based ballpoint pens. Its ink viscosity is between that of water-based and oil-based pens, resulting in smooth writing and good lubrication; it is an upgraded product of oil-based ballpoint pens.

[0003] In existing technologies, the refill and barrel of ordinary ballpoint pens are mostly fixed with hard plastic or metal structures, and the pen tip lacks an effective radial limiting design. When writing, the pen tip and pen tip assembly undergo slight displacement due to uneven force, causing the pen tip to wobble and accompanied by a "beep beep beep" mechanical noise, which interferes with writing concentration. This exacerbates user fatigue, especially during prolonged use. Furthermore, when the user applies pressure to the paper, the friction between the pen tip and the paper increases, leading to hand muscle fatigue and a stiff writing experience, which is particularly unfriendly to students and office workers who need to write frequently.

[0023] 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.

[0024] Please see Figure 1-5 This utility model discloses a shock-absorbing neutral pen, including a pen shell 1. The pen shell 1 contains a pen refill 11. The pen shell 1 also contains a soft rubber straightening sleeve 12 located at one end of the pen tip of the pen refill 11 and a soft rubber buffer pad 13 located at the other end of the pen refill 11. The soft rubber straightening sleeve 12 is designed to fit snugly against the outer diameter of the pen tip of the pen refill 11, thus eliminating the "beep beep beep" shaking noise that occurs with ordinary pens when writing. The soft rubber buffer pad 13 absorbs the writing pressure from the pen tip, reducing the friction between the pen tip and the paper surface under the same writing pressure, keeping the writing pressure within a lighter range, and making the writing experience more comfortable.

[0025] Specifically, the pen casing 1 includes a bottom casing 101 and an upper casing 102, with the bottom casing 101 and the upper casing 102 being threadedly connected at their opposite ends.

[0026] In this embodiment, the bottom shell 101 and the upper shell 102 are connected by threads, which facilitates disassembly and replacement of the pen refill 11 later.

[0027] Specifically, the bottom shell 101 is movably fitted with an anti-slip sleeve 15.

[0028] In this embodiment, the anti-slip sleeve 15 can be made of soft rubber material, which is made of silicone. The anti-slip sleeve 15 ensures the smoothness of the pen when the user holds it, and at the same time reduces the occurrence of slippage.

[0029] Specifically, one side of the upper shell 102 is movably hinged to a hanging ear 17 via a hinge seat 16, and a spring 18 located on one side of the hinge seat 16 is also provided between one side of the upper shell 102 and the hanging ear 17.

[0030] In this embodiment, compared to the traditional hook 17 that relies on its own material properties to rebound, the hook 17 is lifted by a spring 18, so that the hook 17 always maintains a stable clamping force.

[0031] Specifically, the soft rubber straightening sleeve 12 is disposed inside the bottom shell 101, and a spring 2 19 is also disposed between the top of the soft rubber straightening sleeve 12 and the bottom step of the pen refill 11.

[0032] In this embodiment, at the stepped area formed by the reduced diameter at the bottom of the pen refill 11, when the pen refill 11 is pressed, the second spring 19 is compressed through the bottom stepped area. The second spring 19 continuously applies a rebound force to the pen refill 11, which is used in conjunction with the pen refill drive mechanism 14.

[0033] Specifically, the pen casing 1 is internally provided with a pen refill drive mechanism 14 for driving the pen refill 11 to extend and retract. The pen refill drive mechanism 14 includes a rotating component 141 and a drive component 142. The top of the soft rubber buffer pad 13 is movably inserted into the interior of the rotating component 141. The top of the drive component 142 extends to the top of the upper shell 102. The bottom of the drive component 142 is provided with a ring of drive teeth 143. The top of the rotating component 141 is provided with a ring of helical teeth 144 that match the drive teeth 143. The inner wall of the upper shell 102 is provided with a plurality of slides 103 and positioning grooves 104. The slides 103 and positioning grooves 104 are spaced apart. The exterior of the drive component 142 is provided with a plurality of sliders 145. The sliders 145 and the helical teeth 144 are slidably connected to the interior of the slides 103.

[0034] In this embodiment, the automatic pen drive structure is the automatic retraction mechanism of the pen refill 11 commonly used in ballpoint pens and gel pens. When the user needs to extend the pen refill 11, pressing the drive component 142 causes it to descend. The drive component 142 abuts against the rotating component 141 and the pen refill 11, causing it to descend. The spring 19 is compressed at the bottom of the pen refill 11, and the drive component 142 drives the slider 145 to slide inside the slide rail 103. The drive component 142 does not rotate. The drive teeth 143 at the bottom of the drive component 142 are partially misaligned with the helical teeth 144. When the drive component 142 descends and drives the drive tooth 143 to contact the helical tooth 144, the helical tooth 144 descends and slides out from the inside of the slide rail 103. It is then rotated by the contact of the helical tooth 144, so that the helical tooth 144 is opposite to the positioning groove 104. When the drive component 142 is released, the spring 19 rebounds and lifts the pen refill 11, the soft rubber buffer pad 13, the rotating component 141 and the drive component 142 to rise. At this time, the helical tooth 144 is stuck inside the positioning groove 104 and cannot rise to the correct position, so that the pen tip of the pen refill 11 is exposed, and writing can be performed.

[0035] In summary, this shock-absorbing gel pen features a soft rubber straightening sleeve 12. The inner diameter of the sleeve 12 fits snugly against the outer diameter of the pen tip, eliminating the "drip-drip-drip" noise common with ordinary pens. The soft rubber cushioning pad 13 absorbs writing pressure from the pen tip, reducing friction between the pen tip and the paper surface under the same writing pressure. This keeps the writing pressure relatively light, resulting in a more comfortable writing experience. The pen's simple and compact structure is economical and has broad application prospects.
