Description

DIY combined pen

The technical field is as follows:

the utility model belongs to the stationery field, in particular to DIY combination pen especially utilizes a pen-holder two, can pack into the refill of different colors as required respectively, makes up the various pen, gel pen, the former pearl pen etc. of different colours.

Background art:

patent application No. 2012102866743 discloses a miniature double-colored pen, including colored pen I and colored pen II, this colored pen I all includes linking up external screw thread and pen-holder external screw thread with colored pen II, and the length that links up the external screw thread is less than the length of pen-holder external screw thread, and simultaneously, miniature double-colored pen includes the double-end pen socket, and the both ends of this double-end pen socket all are equipped with the internal thread, and link up external screw thread, pen-holder external screw thread and internal thread and all match. The color pen with the structure is not a complete structure and can be used for moisturizing and protecting the pen point only by being matched with the pen holder, and one pen holder can only be matched with two color pens, so that the use is troublesome.

The invention content is as follows:

the utility model aims at designing a DIY combination pen which utilizes two ends of a pen holder to match with a plurality of refills and combines different colors.

The utility model discloses technical scheme realizes like this: the utility model provides a DIY combination pen, includes pen-holder and two at least refills, and the refill has nib and the water storage core of taking writing, drawing nib, its characterized in that: the pen holder is of a cylindrical structure, and interfaces with the same specification are formed at two ends of the pen holder; the pen point of the pen core is provided with a pen cap towards the pen point end, one end of the pen core, which faces the water storage core, is provided with a frustum section capable of being matched with the interface of the pen holder, and the frustum section is positioned on the interface of the pen holder.

The pen holder is characterized in that internal threads are formed on the interfaces at the two ends of the pen holder, external threads are formed on the pen core frustum section matched with the internal threads, and the internal threads and the external threads are connected and positioned in a threaded matching mode.

The interfaces at the two ends of the pen holder are matched with the pen core frustum section, and the pen core frustum section are connected and positioned in an interference fit mode.

The pen point of the pen core is provided with anti-slip lines for holding the pen, a convex ring is arranged on the frustum section towards the pen tip, and the pen cap is positioned by utilizing the convex ring; the pen cap is embedded with a sealing cap which can abut against the frustum section to form a sealing effect on the pen point.

The refill of the utility model has a complete structure, and can be matched with the pen holder to combine a double-head color pen, a gel pen, a ball-point pen and the like which can be used for writing; the combination of thickness matching or double-color matching can be realized by DIY, and the operation is convenient; a plurality of pen cores are combined by using a pen holder, so that the pen sleeving cost is saved, and the waste can be reduced.

Description of the drawings:

the present invention will be further explained with reference to the following specific drawings:

FIG. 1 is a schematic view of a DIY pen assembly

FIG. 2 is an exploded view of a DIY pen assembly

FIG. 3 is a cross-sectional view of a DIY pen assembly

FIG. 4 is an enlarged view of part A of FIG. 3

Wherein

The specific implementation mode is as follows:

referring to fig. 1 to 4, the DIY combination pen includes a barrel 1 and a cartridge 2; the penholder 1 is of a cylindrical structure, interfaces 11 with the same specification are formed at two ends of the penholder, internal threads 12 are formed at the interfaces, and the penholders 2 with different colors or thicknesses are assembled by means of the interfaces 11.

The pen core 2 comprises a pen head 21, a water storage core 22 and a pen point 23, wherein the water storage core 22 and the pen point 23 are respectively arranged at two ends of the pen head 21; the pen point of the pen core 2 is provided with a pen cap 3 towards the pen point end, one end of the pen core is provided with a frustum section which can be matched with the interface of the pen holder, an external thread 24 is formed on the frustum section, and the frustum section is positioned on an internal thread 12 of the interface of the pen holder by virtue of the external thread 24 on the frustum section to form the writing pen which is comfortable to hold.

Furthermore, the pen point 21 of the pen core is provided with an anti-slip pattern 211 for holding the pen, a frustum section 212 facing the pen tip is provided with a convex ring 213, and the convex ring 213 is used for positioning the pen cap 3; the pen cap 3 is embedded with a sealing cap 31, and the sealing cap 31 can be abutted against the frustum section 212 to form a sealing effect on the pen point 23.

In addition, the matching of the penholder 1 and the refill 2 can also directly adopt interference fit except adopting threaded fit, namely, the interfaces 11 at the two ends of the penholder are matched with the refill frustum section 212 matched with the interfaces, the frustum section 212 of the refill is directly utilized to be inserted into the interface 11 of the penholder, and the positioning is formed by interference; certainly, if the matching of a convex ring and the like is added at the frustum section and the interface, the positioning tightness is greatly improved.
