Abstract
Description
Technical Field
[0001] This utility model relates to the field of ballpoint pen technology, and in particular to a ballpoint pen press structure. Background Technology
[0002] A gel pen is short for a ballpoint pen with gel ink. It is a relatively new writing tool that offers a comfortable writing experience. The ink has low viscosity and contains lubricating substances, resulting in a writing medium with a viscosity between water and oil. Gel pens are categorized into push-button gel pens and cap-type gel pens based on their usage. Push-button gel pens extend and retract the ink cartridge using a push-button mechanism on the pen tube. Pressing the push-button extends the cartridge for writing, and pressing it again retracts it. This cycle allows the cartridge to switch between two states.
[0003] However, in actual use, the press button on the top of the ballpoint pen is prone to accidental operation. That is, the pen refill may not be exposed as intended. For example, when the ballpoint pen is carried in a clothing pocket, the refill may be exposed due to accidental bumping or pressing of the press button. The exposed refill can easily leave a lot of ink scratches in the pocket, and may even puncture the clothing or injure the user's skin, which is not conducive to the user's carrying and use.
[0004] Therefore, it is necessary to provide a new press-type structure for a ballpoint pen to solve the above-mentioned technical problems. Utility Model Content
[0005] To address the technical problem of existing gel pen press structures lacking limiting mechanisms and being prone to accidental activation, this utility model provides a gel pen press structure.

The locking structure includes a connecting piece hinged to the fixing cylinder, a limiting plate hinged to the connecting piece via a connecting shaft, and a locking block fixed to the limiting plate. The support plate is provided with a slot for accommodating the locking block.
[0007] Preferably, the fixing cylinder is made of iron, the limiting plate is fixed with a magnetic piece that can be attracted to the fixing cylinder to stabilize the position of the limiting plate, and the pen body is made of plastic.
[0008] Preferably, the fixed cylinder has an opening for providing a channel for the card block to enter and exit, the pen body is equipped with an mounting plate, the mounting plate is fixed with a rotating shaft, and an adjusting cylinder connected to the connecting piece is movably sleeved outside the rotating shaft.
[0009] Preferably, the pen body is equipped with a connecting tube for sealing the pen body, the pen body contains a ballpoint pen refill, and the connecting tube is covered with an anti-slip sleeve to increase grip friction.
[0010] Preferably, the inner wall of the pen body is provided with a toothed groove, a guide rod is movably installed inside the pen body, a locking ring is provided on the guide rod that contacts the toothed groove, the cap contacts the locking ring, a spring is provided on the outer sleeve of the ballpoint pen refill to assist the locking ring in resetting, and the guide rod contacts the ballpoint pen refill.
[0011] Preferably, the top of the cap has a pressing notch with anti-slip texture, and an extension ring for supporting the spring is installed on the inner wall of the pen body.
[0012] Preferably, a hanging rod for hanging a ballpoint pen is provided on one side of the pen body, and a protrusion for increasing the hanging limit is provided on the side of the hanging rod near the pen body.
[0013] Compared with related technologies, the gel pen press structure provided by this utility model has the following beneficial effects: This utility model provides a press-type structure for a ballpoint pen: By incorporating a locking mechanism, the pen's pressing mechanism is prevented from being accidentally operated.

Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0017] Please refer to the following: Figures 1-4 ,in, Figure 1 A front view schematic diagram of a preferred embodiment of the gel pen press structure provided by this utility model; Figure 2 for Figure 1 An enlarged structural diagram of part A shown in the figure; Figure 3 for Figure 2 An enlarged structural diagram of part B shown in the figure; Figure 4 This is a schematic diagram of the assembly structure of the pen body 1 and the locking ring 18 in this utility model.
[0018] The gel pen's press-button structure includes: a pen body 1; a press cap 2 mounted on the pen body 1 for adjusting the extension and retraction of the gel pen tip; a fixing cylinder 3 fixed to the pen body 1; a support plate 4 mounted on the press cap 2 and extending into the fixing cylinder 3; and a locking structure mounted on the support plate 4 to lock the height of the support plate 4 to prevent accidental operation. The locking structure includes a connecting piece 9 hinged to the fixing cylinder 3, a limiting plate 11 hinged to the connecting piece 9 via a connecting shaft 10, and a locking block fixed to the limiting plate 11. The support plate 4 has a slot for accommodating the locking block. By setting up the locking structure, accidental operation of the gel pen's press-button is prevented. In normal use, the locking structure does not affect the normal pressing and adjustment function of the cap 2 for the extension and retraction of the pen tip. However, when the pen is placed in a pocket or other situation where accidental contact may occur, the locking block is inserted into the slot of the support plate 4 to lock the height of the support plate 4. This prevents the cap 2 from being accidentally touched or pressed, thus avoiding accidental exposure of the pen tip. It effectively prevents the exposed pen tip from leaving ink scratches in the pocket, reduces the risk of puncturing clothing or injuring the user's skin, and improves the safety and convenience of carrying and using the pen.
[0019] The fixing cylinder 3 is made of iron, and a magnetic piece 12 that can be attracted to the fixing cylinder 3 to stabilize the position of the limiting plate 11 is fixed on the limiting plate 11. The pen body 1 is made of plastic. By setting up the iron fixing cylinder 3, the magnetic piece 12 that can be attracted to the fixing cylinder 3 and fixed on the limiting plate 11, and the plastic pen body 1, the iron fixing cylinder 3 provides a stable base for the magnetic piece 12 to be attracted. When the limiting plate 11 needs to be fixed in position to prevent accidental contact, the magnetic piece 12 can be tightly attracted to the fixing cylinder 3, which plays a role in stabilizing the position of the limiting plate 11. This effectively avoids the limiting plate 11 from shifting due to shaking or other factors during carrying, thereby preventing the pen refill from being accidentally exposed and reducing the risk of ink scratches, tearing clothing, or puncturing the skin. The pen body 1 is made of plastic. On the one hand, plastic is lighter, making the whole ballpoint pen more portable and reducing the burden on the user. On the other hand, the plastic material will not interfere with the magnetic attraction between the magnetic piece 12 and the iron fixing cylinder 3, ensuring the stability and reliability of the locking structure.
[0020] The fixed cylinder 3 has an opening 5 for providing a channel for the card block to enter and exit. The pen body 1 is equipped with an mounting plate 6, and a rotating shaft 7 is fixed on the mounting plate 6. An adjusting cylinder 8 connected to the connecting piece 9 is movably sleeved outside the rotating shaft 7. By setting the opening 5 on the fixed cylinder 3, the mounting plate 6 on the pen body 1, the rotating shaft 7 fixed on the mounting plate 6, and the adjusting cylinder 8 movably sleeved outside the rotating shaft 7 and connected to the connecting piece 9, the stability of the pressing structure is increased. The opening 5 on the fixed cylinder 3 provides a channel for the card block to enter and exit. When it is necessary to lock or unlock the height of the support plate 4, the card block can smoothly pass through the opening 5 to engage or disengage with the slot on the support plate 4. The mounting plate 6 installed on the pen body 1 provides a stable mounting base for the rotating shaft 7. The setting of the rotating shaft 7 and the adjusting cylinder 8 allows the connecting piece 9 to rotate flexibly, thereby driving the limiting plate 11 to move, realizing the engagement or disengagement of the card block with the slot.
[0021] A connecting sleeve 14 for sealing the pen body 1 is installed on the pen body 1. The pen body 1 contains a ballpoint pen refill. The connecting sleeve 14 is covered with an anti-slip sleeve 15 to increase grip friction. By setting the connecting sleeve 14 on the pen body 1 to seal the pen body 1, and covering the connecting sleeve 14 with an anti-slip sleeve 15 to increase grip friction, the dual effects of improving the performance of the ballpoint pen and the user experience are achieved. The connecting sleeve 14 plays a good sealing role for the pen body 1. It can effectively protect the ballpoint pen refill inside the pen body 1, prevent external dust, debris, etc. from entering the pen body 1, avoid contamination or damage to the refill, thereby extending the life of the refill, ensuring smooth ink output during writing, and improving the writing quality. The anti-slip sleeve 15, covered by the connecting sleeve 14, greatly increases the friction when the user holds the ballpoint pen. During the writing process, even if the hand is sweaty or there is slight slippage, the anti-slip sleeve 15 can ensure that the user holds the pen firmly and is not prone to slippage, making writing smoother and reducing writing errors caused by hand slippage.
[0022] The inner wall of the pen body 1 is provided with a toothed groove 16. A guide rod 17 is movably installed inside the pen body 1. A locking ring 18 is provided on the guide rod 17, which contacts the toothed groove 16. The button cap 2 contacts the locking ring 18. A spring is provided on the outer sleeve of the ballpoint pen refill to assist the locking ring 18 in resetting. The guide rod 17 contacts the ballpoint pen refill. Through the toothed groove 16, the guide rod 17, the locking ring 18, the button cap 2 that contacts the locking ring 18, the spring that assists the locking ring 18 in resetting, and the guide rod 17 that contacts the ballpoint pen refill, the pen is controlled. The refill extension effect is achieved by the toothed groove 16 on the inner wall of the pen body 1 cooperating with the locking ring 18 on the guide rod 17. When the cap 2 is pressed, the locking ring 18 can move between the toothed grooves 16, realizing graded control of the refill extension. This allows the user to flexibly adjust the exposed length of the refill according to their needs. The spring assists the locking ring 18 to reset. After the pressing operation is completed, the locking ring 18 can be quickly pulled back to its original position to ensure the stability of the structure. The guide rod 17 contacts the pen refill and plays the role of transmitting the pressing power and guiding the direction of the refill extension.
[0023] The top of the button cap 2 has a pressing notch with anti-slip texture. An extension ring for supporting the spring is installed on the inner wall of the pen body 1. The pressing notch on the top of the button cap 2 provides a clear pressing position for the user's fingers, making the pressing operation more targeted and avoiding the inconvenience caused by blind pressing, thus improving the accuracy of operation. The anti-slip texture in the pressing notch further enhances the friction between the finger and the button cap 2, ensuring stable execution of the pressing action even when the user's hands are sweaty or in a relatively humid environment, effectively preventing the fingers from slipping during pressing, making the pressing operation smoother and less strenuous. The extension ring installed on the inner wall of the pen body 1 provides stable support for the spring, allowing the spring to maintain the correct position and direction during extension and retraction, ensuring the stable and reliable reset function of the spring on components such as the locking ring 18. This not only facilitates the smooth extension and retraction of the pen refill but also extends the service life of the entire pressing structure and reduces the probability of failure caused by spring displacement or deformation.
[0024] A hanging rod 13 for hanging ballpoint pens is provided on one side of the pen body 1. The side of the hanging rod 13 near the pen body 1 has a protrusion for increasing the hanging limit. The hanging rod 13 provides users with a variety of storage options. In daily life, users can easily hang the ballpoint pen on the side pocket of a backpack, the edge of a folder, or the partition of an office desk, etc., for easy access. This avoids the problem of losing or finding the ballpoint pen due to random placement, greatly improving the convenience of use. The protrusion on the side of the hanging rod 13 near the pen body 1 acts as a limit. When the ballpoint pen is hung in the corresponding position, the protrusion can effectively prevent the ballpoint pen from easily slipping off due to shaking or external force during the hanging process. It increases the friction and resistance when hanging, so that the ballpoint pen can stay firmly at the hanging position, reducing the risk of damage caused by the pen falling.
[0025] The working principle of the gel pen press structure provided by this utility model is as follows: In use, the user places their finger on the pressing notch at the top of the button cap 2 and presses it down. The button cap 2 contacts the locking ring 18, causing the locking ring 18 to move between the teeth 16 on the inner wall of the pen body 1. The guide rod 17 contacts the pen refill, transmitting the pressing force and guiding the refill's extension and retraction direction. Simultaneously, the spring that assists in the locking ring 18's reset is compressed during the pressing process, achieving graded control of the refill's extension and retraction, allowing the user to flexibly adjust the exposed length of the refill as needed. After the pressing operation is completed, the spring quickly pulls the locking ring 18 back to its original position. To ensure structural stability and keep the pen refill in its corresponding extension and retraction state, when the pen needs to be placed in a pocket or other place where it may be accidentally touched, the adjusting cylinder 8 is rotated. The adjusting cylinder 8 drives the connecting piece 9 to rotate, and the connecting piece 9 drives the limiting plate 11 to move through the connecting shaft 10. This causes the magnet 12 fixed on the limiting plate 11 to be attracted to the iron fixing cylinder 3. At this time, the locking block extends into the locking slot, which plays a role in stabilizing the position of the limiting plate 11. At this time, even if the button 2 is accidentally touched or pressed, the button 2 will not drive the support plate 4 to move, thus preventing the pen refill from being accidentally exposed.
[0026] This utility model provides a gel pen press structure. By setting a locking structure, it prevents the gel pen press from being accidentally operated. At the same time, it does not affect the adjustment function of the cap 2 for the extension and retraction of the gel pen tip during normal use, avoids accidental exposure of the pen tip, reduces the risk of ink scratches, tearing clothing or puncturing the skin, and improves the safety and convenience during carrying and use.
