Description of the embodiments

The invention is further described below with reference to the accompanying drawings.

The snap-in quick-pull pen shown in fig. 1-5 comprises an outer rod 1, an inner rear rod 2, an inner front rod 3, a return spring 5 and a pen core 4. One or more extending clamping tables 21 are arranged on the inner rear rod 2, and using clamping protrusions 211 are arranged on the extending clamping tables 21. One or more sliding grooves 31 are provided on the inner front rod 3. The chute 31 is provided with a use stopper 311. The outer rod 1 is provided with a limiting ring 11, and the outer rod 1 and the inner rear rod 2 are matched with each other. In particular to the fixing by means of a buckle, threads, magnetic attraction, welding, integral forming and/or adhesive. The pen core 4 is positioned in the inner rear rod 2 and the inner front rod 3. The pen core 4 is fixed at the tail end of the inner rear rod 2. The lower end of the chute 31 is also provided with an anti-drop table 33. The drop-off prevention base 33 is not easy to pass through the limit ring 11. The return spring 5 is located in the inner front rod 3. In particular between the inner front rod 3 and the cartridge 4.

When core extraction is needed: the inner rear rod 2 or the outer rod 1 is kept stationary, and the inner front rod 3 is moved toward one end of the inner rear rod 2, so that the use stopper 311 is locked above the use locking protrusion 211. At this time, the pen core is in a core-out state.

When the core needs to be retracted: the inner rear rod 2 or the outer rod 1 is kept still, so that the inner front rod 3 moves towards one end close to the inner front rod 3, the use limiting table 311 is separated from the use clamping protrusion 211, the influence of the long-distance reset slope 2111 or the reset spring 5 is exerted, and the front-back matching distance between the inner front rod 3 and the inner rear rod 2 is maximized. At this time, the pen core is in a core-out state, and the pen point of the pen core is completely hidden in the inner front rod 3.

In order to achieve a better use experience, the following upgrades are made.

1. The inner front rod 3 is detachable into two parts for assembly, and the rear half of the inner front rod can be used as a non-detachable piece to be assembled in the outer rod. The front half part of the inner front rod 3 is not required to be disassembled, and can be used for disassembling and replacing the pen core when the pen core is replaced.

2. The inner rear rod 2 can be split into two parts for assembly, so that the installation and the production are facilitated, otherwise, when metal parts are manufactured, the structure of the inner rear rod 2 is too complex and long, and the actual production is not facilitated. The inside still needs to draw the blank place that carries out the refill, and the size location also can increase the processing degree of difficulty to then need whole metal consumable processing, can be extravagant, but the back of split, then the front half of interior back pole 2 can adopt hollow metal consumable to replace. And is also more beneficial to the assembly and manufacture of the pen clip.

3. The outer rod 1 and the limiting ring 11 can be split into two parts for assembly. The outer rod 1 is prevented from being scratched by the moving inner front rod 3 when the outer rod 1 is made of plastic, in particular transparent plastic. Therefore, the outer rod 1 is preferably not contacted to the inner front rod 3. After the spacing ring 11 is detached to be an independent part, the outer rod can be realized to adopt a transparent plastic part, and the spacing ring 11 is replaced by a metal part or an opaque wear-resistant plastic part, so that the wear resistance and the aesthetic degree of the whole appearance are improved.

In order to make the whole operation process smoother and more natural, and improve the durability of the use. The side of the chute 31 is also provided with a release slot 32. The lower end of the using clamp protrusion 211 is provided with a long-distance resetting slope 2111.

In order to enable a smoother switching of the take-up and take-off states. The use catching protrusion 211 is provided with a non-use detachment slope 2112, and the use stopper 311 is provided with a non-use detachment auxiliary slope 3111 and a use cut-in auxiliary slope 3112.

The angle between the non-use of the disengagement ramp 2112 and the non-use of the disengagement assist ramp 3111 described above is matched to ensure a better disengagement between the non-use of the disengagement ramp 2112 and the non-use of the disengagement assist ramp 3111. The above-described non-use escape slope 2112 and non-use escape auxiliary slope 3111 have a certain inclination angle.

The inclination angle between the pen body axis and the auxiliary separation slope 3111 without using the separation slope 2112 has good effect between 30 and 80 degrees, and the optimal angle is between 50 and 75 degrees; of course, the actual movable distance between the use of the catch 211 and the use of the stop 311 is largely determined by the deformability of the body carried by the use of the catch 211 and the use of the stop 311. The specific separation force is larger than the external force of shaking and the elasticity of the reset spring which can be caused when normal writing is performed at ordinary times.

When the main body is deformed by using the clamping protrusion 211 and the limiting table 311, the main body is preferably deformed transversely, rather than vertically, so that the pen refill 4 and the outer rod 1 are prevented from being contacted, and unnecessary friction contact and abrasion of the outer rod 1 are avoided.

The use of the cut-in auxiliary ramp 3112 may better assist in extending the catch 21 into the chute 31.

Examples

A snap-in quick pull pen as shown in fig. 13 or 19, comprising an outer rod 1, an inner rear rod 2, an inner front rod 3 and a cartridge 4. One or more extending clamping tables 21 are arranged on the inner rear rod 2, and using clamping protrusions 211 are arranged on the extending clamping tables 21. One or more sliding grooves 31 are provided on the inner front rod 3. The chute 31 is provided with a use stopper 311. The outer rod 1 is provided with a limiting ring 11, and the outer rod 1 and the inner rear rod 2 are matched with each other. In particular to the fixing by means of a buckle, threads, magnetic attraction, welding, integral forming and/or adhesive. The pen core 4 is positioned in the inner rear rod 2 and the inner front rod 3. The pen core 4 is fixed at the tail end of the inner rear rod 2. The side of the chute 31 is also provided with a release slot 32. The lower end of the chute 31 is also provided with an anti-drop table 33. The drop-off prevention base 33 is not easy to pass through the limit ring 11. The lower end of the using clamp protrusion 211 is provided with a long-distance resetting slope 2111.

The adoption of the anti-deflection sliding column and/or the method for preventing the two sides of the sliding groove from tilting can better ensure that the clamping convex 211 and the limiting table 311 are used for bearing the main body to realize transverse deformation, and the method for preventing the two sides of the sliding groove has a lower effect than the combination effect of the anti-deflection sliding column and the anti-deflection sliding groove, because the anti-deflection sliding column and the anti-deflection sliding groove can ensure that the two sides of the sliding groove do not deviate up and down, the anti-deflection of the two sides of the sliding groove can only be realized without upwards deviation, and the inner wall of the outer rod is not ground. However, there is some influence on the cartridge, but this influence falls within an acceptable range, and thus an effective solution.

The manufacturing process comprises the following steps: the inner structure of the pen outer rod is difficult to manufacture no matter the pen is made of metal or plastic, and many processes are difficult to manufacture at present, and some processes cannot be manufactured at present. Although 3D printing can be realized, 3D printing is currently costly to produce and slow to produce. Because of the problem of the manufacturing process, the 3D printed finished product is brittle, stable in size and mass production, large in vertical deviation and poor in smoothness. The assemblability cannot be very stable and fine. The external penetrability processing is very simple and easy to realize. Either existing processes or 3D printing may be perfectly adequate.

Description of transparent plastics: at present, the plastic material with good high permeability is mainly PC, but the material is not wear-resistant. At present, no transparent plastic can be wear-resistant and high-permeability, and cannot bear long-term movement of the inner part even if the transparent plastic is wear-resistant. Therefore, if the outer rod with the conventional structure adopts transparent plastic, the inner part of the outer rod is worn after a period of use, so that the high-permeability effect is poor.

The problem can be perfectly solved by the following method:

1. By adopting the structural design of the invention, most of the problems can be solved, and the influence is reduced to be small;

2. after the outer rod structure is disassembled and reassembled, the problem of abrasion can be further solved;

3. by adopting the scheme of embodiment 5, through the method of preventing the deflection of the sliding column and/or preventing the two sides of the sliding chute from tilting, the influence of the outer rod can be reduced to 0 by ensuring the use of the clamping convex 211 and the use of the limiting table 311 to bear the main body to realize transverse deformation, so that the problem of abrasion caused by the inner part of the outer rod in the use process is completely avoided.

In order to ensure high transparency and better texture, the outer rod can be made of glass, so that the outer rod is more transparent and has wear resistance, but the glass is high in manufacturing cost and high in manufacturing difficulty, and meanwhile, the outer rod is easy to damage and has residues after being broken, so that the outer rod can be only used as a candidate scheme.
