Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ballpoint pens, in particular to a drop-proof ballpoint pen. Background Art
[0002] A ballpoint pen is a pen that uses a ball at the front end of the pen or refill to roll out the writing medium. The ball is made of brass, steel or tungsten carbide and can release ink onto paper when writing. Ballpoint pens are easy to use and durable and are therefore very popular in people's daily lives. As there are many students among them, the production of ballpoint pens is increasing day by day. A ballpoint pen is composed of a pen barrel, a pen cap, a pressing device and a refill. The refill of the ballpoint pen can be put in and out by simply pressing the pen cap at the top of the ballpoint pen.
[0003] In daily life, when using a ballpoint pen, the shell of the ballpoint pen does not have a drop-proof structure. When the ballpoint pen slips from your hand and falls to the ground, the pen core may be deformed due to the collision, resulting in intermittent oil flow during subsequent writing. In severe cases, the pen ball may fall out of the pen tip due to the collision, making the ballpoint pen unusable.
[0004] Therefore, it is particularly important to design a drop-proof ballpoint pen to solve the above-mentioned defects. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0026] Example:
[0027] The utility model provides a drop-proof ballpoint pen, which aims to solve the technical problem that the shell of a ballpoint pen in the prior art does not have a drop-proof structure, and when the ballpoint pen slips from the hand, it cannot provide shock absorption protection for the pen core, resulting in damage to the pen core;
[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0029] First, see Figure 1-Figure 3A drop-proof ballpoint pen comprises a pen cover 1, a mounting head 101 is threadedly connected to the top of the pen cover 1, and the mounting head 101 is threadedly connected to the pen cover 1, so as to facilitate the replacement of the pen core 3. A pressing structure 2 is provided inside the mounting head 101 and located inside the pen cover 1, and the pressing structure 2 controls the extension and fixation of the pen tip. A pen cap 201 is fixedly connected above the pressing structure 2 and located on the top of the mounting head 101, and a pen clip 2011 is fixedly connected to one side of the pen cap 201.
[0030] Among them, see Figure 2-Figure 3 A pen core 3 is embedded in the pen cover 1 below the pressing structure 2, a clamping ring 301 is fixedly connected to the outside of the pen cover 1, a limit card 302 is fixedly connected to the inside of the pen cover 1, a spring bar 3011 is arranged between the clamping ring 301 and the limit card 302 and on the outside of the pen core 3, and the pen core 3 assists the pen core 3 to extend and retract through the spring bar 3011, the clamping ring 301 and the limit card 302.
[0031] For further information, see Figure 2-Figure 4 A protective cover 4 is provided at a position of the pen core 3 near the pen tip and inside the pen cover 1, and sliding rods 401 are fixedly connected on both sides of the protective cover 4. A support bar 402 is fixedly connected inside the pen cover 1 and below the sliding rod 401, and a spring bar 2 403 is fixedly connected between the support bar 402 and the sliding rod 401. Bar slide grooves 404 are provided on both sides of the pen cover 1 and at positions corresponding to the sliding rod 401, and the sliding rod 401 is slidably connected to the bar slide groove 404. The elastic force of the spring bar 2 403 drives the protective cover 4 to freely retract and retract to protect the pen tip, and a pair of positioning slots 4041 are provided on both sides of the top of the bar slide groove 404.
[0032] For further information, see Figure 1-Figure 4 A pressing block 5 is provided at one end of the sliding rod 401 away from the refill 3. The pressing block 5 is fixedly connected to the sliding rod 401 through a spring bar 3 501. A pressing groove 502 is provided on one side of the pressing block 5. The pressing block 5 is made of natural rubber. A plug-in strip 503 is fixedly connected to the corresponding position of the pressing block 5 and the positioning slot 4041. The pressing block 5 is plugged and connected to the positioning slot 4041 through the plug-in strip 503. When the ballpoint pen needs to be used for writing, the pressing block 5 is used to drive the sliding rod 401 to move upward. By pressing the pressing block 5, the spring bar three 501 is forced to shrink, the plug-in strip 503 is embedded in the interior of the positioning slot 4041, and the protective cover 4 is retracted into the pen cover 1. The writing posture can be maintained by pinching the pressing block 5 to write. When the ballpoint pen is out of the hand, the spring bar three 501 performs a reset movement, the plug-in strip 503 is separated from the interior of the positioning slot 4041, and the spring bar two 403 performs a reset movement, so that the sliding rod 401 slides downward, driving the protective cover 4 to slide out of the pen cover 1 to protect the pen tip.

The rubber anti-fall cover 6 can alleviate the impact force received by the ballpoint pen when it falls to the ground through the spring group 601, thereby providing shock absorption protection for the ballpoint pen.
[0034] In addition, it should be supplemented according to the content of the above embodiment that the pressing structure 2 is a prior art, and its internal working principle and operation process will not be described in detail here.
[0035] The working process of the utility model is as follows: first, the installation head 101 is connected with the pen cover 1 by a thread, so as to facilitate the installation and replacement of the pen core 3. When the ballpoint pen needs to be used for writing, the pen cap 201 is pressed to make the pressing structure 2 control the pen tip to extend, and the pen core 3 is assisted to extend and retract by the spring strip 1 3011, the clamping ring 301 and the limit clamp 302. The pressing block 5 is used to drive the sliding rod 401 to move upward, and the spring strip 3 501 is contracted by pressing the pressing block 5, and the plug-in strip 503 is embedded in the interior of the positioning slot 4041, and the protective cover 4 is retracted into the pen cover 1. The writing posture is maintained and the pressing block 5 is pinched to proceed. When writing in running script, when the ballpoint pen is out of the hand, the spring bar three 501 performs a reset movement, the connecting bar 503 is separated from the interior of the positioning slot 4041, and the spring bar two 403 performs a reset movement, so that the sliding rod 401 slides downward, driving the protective cover 4 to slide out of the pen cover 1 to protect the pen tip, and the rubber anti-fall cover 6 can alleviate the impact force received by the ballpoint pen falling to the ground through the spring group 601, and provide shock-absorbing protection for the ballpoint pen. The whole operation process is simple and convenient. Compared with the existing ballpoint pens, the utility model can enhance the anti-fall performance of the ballpoint pen through design, and can protect the ballpoint pen tip while providing shock-absorbing protection.
