Description

A new type of pen

Technical field

The utility model belongs to the field of writing instruments, specifically a new type of pen.

Background technique

Pen is a common hand-held writing instrument. Commonly used pens are composed of a pen core, a pen barrel, a pen cap, and a sealing head. The pen core is usually inserted into the pen barrel. When writing, the hand holds the pen barrel and drives the pen core. The pen tip at the front spits out ink on the paper.

The Chinese patent number is CN201920781296.3, and the patent name is Pen Cap and Its Pen. It is mentioned that the pen cap is equipped with an inner lining, and the inner lining is provided with a pen tip receiving cavity.

Both ends of the pen barrel 16 are open structures. One end of the pen barrel 16 is provided with an opening on the inner wall. There is a sealing block 2, and a perforation is provided on the sealing block 2. The pen tip end of the pen core 14 can pass through the perforation. A first connecting rod 3 is provided on one side wall of the sealing block 2, and one end of the first connecting rod 3 is provided with a third connecting rod 3. a threaded rod 4, a first threaded rod 4

The inner wall of the pen holder 16 is provided with a first orifice plate 5. The first threaded rod 4 can penetrate the first orifice plate 5. A first hole is provided on one side wall of the pen holder 16, and two second holes are symmetrically arranged on the inner wall of the first hole. Axle seat 19, a third gear 18 is provided between the two second axle seats 19, and a fourth gear 22 is provided on one side of the third gear 18;

The inner wall of the pen holder 16 is provided with second clamping plates 20 on both sides close to the fourth gear 22. The second clamping plate 20 is provided with a through hole 25. The first threaded rod 4 passes through the through hole 25. The side walls of the second clamping plate 20 are provided with There is a second round rod 21, and circular grooves 23 are provided on both side walls of the fourth gear 22. The second round rod 21 can extend into the circular groove 23;

A threaded hole 24 is provided in the middle of the fourth gear 22 , and the first threaded rod 4 is threadedly engaged with the threaded hole 24 .

In some examples, a spring 13 is fixed on the side of the stopper 11 close to the pen core 14, and a guide rod 12 is provided at the middle position of the stopper 11 close to the spring 13;

When retracting the pen tip and protective case 1, use your fingers to push the third gear 18 counterclockwise. The third gear 18 drives the fourth gear 22 to rotate. The first threaded rod 4 moves on the fourth gear 22, and the first threaded rod 4 drives the first Connecting rod 3, the first connecting rod 3 pulls the sealing block 2, the sealing block 2 drives the protective shell 1, and at the same time pushes the retaining ring 17, the retaining ring 17 drives the pen core 14 to move, and the pen tip of the pen core 14 will move to the inside of the pen barrel 16;

In some examples, the guide rod 12 has a cylindrical structure, the diameter of the pen core 14 is larger than the diameter of the guide rod 12 , and the extended end of the guide rod 12 can be inserted into the interior of the extended end of the pen core 14 .

In some examples, a retaining ring 17 is provided on one end of the pen core 14 close to the pen tip.

In some examples, a protective shell 1 is provided at one end of the sealing block 2 .

By adopting the above technical solutions:

when using it,

Install the pen core 14: take out the stopper 11, insert the end of the pen core 14 with the pen tip into the pen holder 16 first, and the pen tip passes through the perforation of the sealing block 2. After the retaining ring 17 on the pen core 14 reaches the position of the sealing block 2, the pen tip If it cannot continue to move, then insert the stopper 11 into the opening at one end of the pen barrel 16. At this time, the spring 13 is in contact with the tail end of the pen core 14;

When writing, the user pushes the third gear 18 clockwise with his finger, and the third gear 18 rotates. The third gear 18 drives the fourth gear 22 to rotate. The fourth gear 22 does not move when it rotates.

When the fourth gear 22 rotates, the second round rod 21 on the side wall of the second clamping plate 20 blocks the movement of the fourth gear 22, so that the position of the fourth gear 22 does not move, so that the first threaded rod 4 moves on the fourth gear 22. , when the first threaded rod 4 moves, it drives the first connecting rod 3, and the first connecting rod 3 pushes the sealing block 2 to move. At the same time, the tail end of the pen core 14 is pushed by the spring 13, and the pen core 14 moves with the sealing block 2, thereby realizing the pen The pen tip of the core 14 moves to the outside of the pen holder 16, and the user can write on paper by holding the pen holder 16.

Example 2:

The specific structure of this embodiment is shown in Figures 1-4. A stopper 11 is provided on the inner wall of the opening of one end of the penholder 16 relative to the sealing block 2. A second connecting rod 10 is provided on one side wall of the stopper 11, and the third A second threaded rod 9 is provided at one end of the two connecting rods 10 , and a second orifice plate 6 is provided on the inner wall of the pen shaft 16 , and the second threaded rod 9 can penetrate the second orifice plate 6 .

In some examples, a second hole is opened on one side wall of the penholder 16, and two first axle seats 151 are symmetrically arranged on the inner wall of the second hole, and the first gear 7 is disposed between the two first axle seats 151. A second gear 15 is provided on one side of the first gear 7, and first clamping plates 8 are provided on both sides of the inner wall of the penholder 16 close to the second gear 15. The first gear 7 and the first shaft seat 151 are connected by a shaft body. , when the first gear 7 rotates, it drives the shaft to rotate, and the shaft rotates on the first shaft seat 151;

In some examples, a first round rod 81 is provided on the side wall of the first clamping plate 8, a round hole is opened on the first clamping plate 8, and the second threaded rod 9 can penetrate the round hole;

The second gear 15 is also provided with a threaded hole 24 in the middle. When the second gear 15 rotates, the second threaded rod 9 moves on the second gear 15;

The side wall of the second gear 15 is also provided with a circular groove. The first round rod 81 can extend into the circular groove. When the second gear 15 rotates, the first round rod 81 is in the circular groove. Sliding, so that the position of the second gear 15 can be maintained, and the second gear 15 will not be displaced.

By adopting the above technical solutions:

When in use, when writing, when the user holds the penholder 16 and writes with greater force, the pen core 14 is pressed harder, and at the same time, the tail end of the pen core 14 squeezes the spring 13, because the spring 13 is elastic. , the pen tip of the pen core 14 shakes on the paper, which is not conducive to stable writing. At this time, you can push the first gear 7 clockwise with your fingers. The first gear 7 drives the second gear 15 to rotate. When the second gear 15 rotates, the first gear 7 rotates. The second threaded rod 9 moves in the second gear 15. The second threaded rod 9 pulls the second connecting rod 10. The second connecting rod 10 drives the stopper 11. The stopper 11 moves toward the inside of the pen barrel 16. At this time, the spring 13 squeezes the pen The pen core 14 and the pen core 14 are pressed tightly. When writing, the spring 13 is in a state of being pressed tightly against the pen core 14 and will not bounce around, thereby keeping the pen core 14 stable in the pen barrel 16 .

Finally, it should be noted that: obviously, the above-mentioned embodiments are only examples to clearly illustrate the present invention, and are not intended to limit the implementation. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. An exhaustive list of all implementations is neither necessary nor possible. However, obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
