Description

Pen phase and pen

Technical Field

The utility model relates to the technical field of stationery, in particular to a pen phase and a pen.

Background

The pen point of the watercolor pen is usually fixed by the fixing rib in the pen phase, and the fixing mode can fix the pen point, but the fixing force is small, so that a user can 'stamp' the pen point into the pen phase and even into the pen shell by only using force, and the pen point cannot be taken out for reuse; or the pen point can be pulled out by only one force, so that the watercolor pen is damaged. Especially when the watercolor pencil is used by the young children, the two conditions are frequently caused by the driving of curiosity, so that a limiting structure capable of effectively preventing the pen point from being 'poked in' or pulled out is needed to be provided.

The utility model patent with the application number of CN202120883194.X discloses a pen point anti-falling structure, wherein a pen point sleeve (pen phase) is sleeved outside the pen point, the pen point sleeve is provided with a first sleeve and a second sleeve with reduced inner diameters from top to bottom, the anti-falling structure comprises a clamping groove arranged on the pen point and a clamping table arranged on the inner wall of the second sleeve, four first guide ribs are annularly and equidistantly arranged on the inner wall of the second sleeve along the direction of a central axis, and the clamping table is formed by a tip extending from the top of the first guide ribs towards the central axis. The four clamping tables are all clamped in the clamping grooves, so that the tip sleeve is used for limiting the pen point in the central axial direction, namely, the pen point can be limited upwards and downwards relative to the tip sleeve, the phenomenon that the pen point is prevented from falling off from the tip sleeve in a channeling mode can be effectively prevented, the pen point is not easy to damage, and the normal use function of the pen is guaranteed. The second sleeve inner wall is located between two adjacent first guide convex ribs and is also provided with a second guide convex rib along the central axis direction. The diameter of the circle formed by the one ends of four first guide convex ribs and the second guide convex ribs far away from the inner wall of the second sleeve is matched with the diameter of the pen point, so that the pen point is not only guided when being installed, but also has good positioning and supporting effects on the circumference, the pen point is prevented from shaking, and the stability in use is improved (refer to figure 1).

According to the scheme, the falling of the pen point is effectively prevented by utilizing the matching effect of the clamping groove arranged on the pen point and the clamping table on the guide rib, but ink in the pen core flows to the guide rib/the fixing rib easily when flowing through the pen point, and the ink can be attached to the pen phase for a long time, so that the ink is wasted, and the pen phase and the hand of a user are polluted.

Preferably, the pen is a watercolor pen.

The technical scheme of the utility model has the following beneficial effects:

1) After the pen point is inserted into the first part with smaller inner diameter, the pen point positioned at the outer side of the first part is clamped on the supporting part and cannot be poked into the pen phase, and the part of the pen point is surrounded and supported by the supporting part, so that the shaking of the pen point during writing is avoided; because the diameter of the pen point is larger, the pen point positioned at the inner side of the first part can expand and is clamped in the second part after expansion, so that the pen point cannot be pulled out;

and the pen phase avoids fixing the pen point by using the fixing ribs, the surface is smooth and is not stained with ink (especially is not stained with water-based ink), if ink drips down, the ink can flow back to the pen point again along the smooth surface, the ink in the pen core is prevented from flowing to the fixing ribs and adhering to the pen phase when flowing through the pen point, and the ink is saved while the pen phase is kept clean.

2) The setting of pothook can further block the nib of inflation on the pothook, further reduces the risk that the nib was pulled out.

Detailed Description

The technical scheme of the utility model claimed in the utility model is further clearly described below with reference to the accompanying drawings and specific embodiments.

Example 1

The pen phase provided in this embodiment is shown in fig. 2, in which the pen head 1 is fixed, and the pen phase sequentially includes, from bottom to top, a first portion 2, a second portion 3, and a third portion 4, where the third portion 4 is connected to the pen shell 5. The pen point 1 sequentially penetrates through the cavities of the first part 2, the second part 3 and the third part 4 and then is connected to the pen core 6, and the pen core 6 is accommodated in the pen shell 5. The inner diameter of the second part 3 is larger than that of the first part 2, the inner diameter of the first part 2 is smaller than that of the pen point 1, the lower end of the first part 2 is also connected with a supporting part 7, and the inner diameter of the supporting part 7 is equal to that of the pen point 1.

Since the second portion 3 of the pen phase has an inner diameter smaller than the diameter of said nib 1, the nib 1 can be inserted into the first portion 2 during manufacture by applying a suitable force with the device (but without which the nib can be inserted and extracted). After the pen point 1 is inserted, the pen point positioned at the outer side of the first part 2 is clamped on the supporting part 7 and cannot be poked into the pen, and the pen point is circumferentially supported by the supporting part 7, so that the shaking of the pen point during writing is avoided. Because the diameter of the nib is large, the nib located inside the first portion 2 will expand and then be trapped inside the second portion 3, so that the nib 1 cannot be pulled out.

In addition, the pen phase of the embodiment avoids the use of the fixing ribs for fixing the pen point, the surface is smooth and is not stained with ink (especially is not stained with water-based ink), and if ink is dripped, the ink can flow back to the pen point again along the smooth surface. Compared with the existing design containing the fixing ribs (as shown in the attached figures 1-2), the ink in the pen refill can be prevented from flowing to the fixing ribs and attaching to the pen phase when flowing through the pen point, so that the pen phase is kept clean and tidy, and meanwhile, the ink is saved.

Specifically, the inner side wall at the bottom end of the second portion 3 is provided with an upwardly extending hook 11. Due to the larger diameter of the nib, the nib positioned on the inner side of the second portion 3 will be clamped on the hook 11 after being expanded, so that the risk of the nib being pulled out is further reduced.

Wherein the third part 4 is connected to the inner surface of the pen housing 5 by an outer surface. In particular, the outer surface of the third portion 4 may comprise an external thread for connecting to the inner surface of the pen housing 5. The inner diameter of the third part 4 is larger than that of the second part 3, and the bottom of the pen core 6 abuts against a platform 8 formed by the difference between the inner diameters of the third part 4 and the second part 3. The platform 8 is formed to better secure the cartridge inside the pen housing.

Specifically, the second portion 3 includes a joint member 9 connected to the third portion 4 and a grip portion 10 connected to a lower portion of the joint member 9 for a user to grip, and the grip portion 10 is connected to the first portion 2 and has a tapered diameter from top to bottom.

Wherein the diameter of the engagement member 9 is larger than the diameter of the third portion 4.

Wherein the engagement member 9 is partially accommodated inside the pen housing 5 after the pen housing 5 is coupled with the third portion 4.

In particular, the pen phase is made transparent, for example, from plastic or acrylic.
