Abstract

The utility model discloses a learning pen. The learning pen comprises an outer pen sleeve, a pen point which is arranged at one end of the outer pen sleeve, and a pen refill, wherein a pen point groove corresponding to the pen refill is formed in the pen point; the outer pen sleeve is further internally provided with an inner pen sleeve capable of moving axially along the outer pen sleeve; the pen refill is arranged on the inner side of the inner pen sleeve; a using position or a storage position is arranged between the inner pen sleeve and the outer pen sleeve; when the inner pen sleeve and the outer pen sleeve are located at the using position, the end of the pen refill penetrates through the pen point groove to be located at the outer end; when the inner pen sleeve and the outer pen sleeve are located at the storage position, the end of the pen refill is located at the interior of the outer pen sleeve. According to the learning pen, the pen refill is installed by setting the movable inner pen sleeve, so that the pen refill can switch back and forth between the using position and the storage position conveniently, thus the pen refill is protected from being damaged.

Description

A kind of learning pen

Technical field

The utility model relates to study article technical field, in particular, and particularly a kind of learning pen.

Background technology

Existing learning pen structure generally comprises the pen cap, pen core and nib; and the end of pen core is the exposed outside at pen core; pen core position is also immutable; generally the end that special protective sleeve is protected pen core need to be installed on nib in use; and because protective sleeve is very easy to lose; the easy like this pen core that makes sustains damage, as: drop, collide with etc.Therefore, be necessary to design a kind of novel learning pen.

Utility model content

The purpose of this utility model is to provide a kind of learning pen that can protect pen core to be difficult for sustaining damage.

In order to solve problem set forth above, the technical solution adopted in the utility model is:

A kind of learning pen, comprise the outer pen cap, be located at the nib of outer pen cap one end, and pen core, described nib is provided with the nib groove corresponding with pen core, is also provided with and can makes the axially movable interior pen cap along the outer pen cap in the described outer pen cap, described pen core is located at interior pen cap inner side, and between the described interior pen cap and the described outer pen cap, have use location or memory location, the described interior pen cap and the outer pen cap are when use location, and the end of described pen core is positioned at outer end through nib groove; The described interior pen cap and the outer pen cap are when memory location, and it is inner that the end of described pen core is positioned at the outer pen cap.

According to a preferred embodiment of the present utility model: the inwall of the described outer pen cap is provided with the first locked groove, projection and the second locked groove from top to bottom successively, and the outer wall of the described interior pen cap is provided with the snap close matching with described the first locked groove or the second locked groove; When described projection is positioned at the first locked groove, the described interior pen cap and the outer pen cap are in use location, and when described projection is positioned at the second locked groove, the described interior pen cap and the outer pen cap are in memory location.

According to a preferred embodiment of the present utility model: the surface of described projection is arcwall face, and all matches with snap close in the two ends up and down of described convex curved surface.

Compared with prior art, the beneficial effects of the utility model are: the utility model is installed pen core by the pen cap in arranging movably, can make pen core between use location and memory location, switch back and forth easily, and then protection pen core is difficult for sustaining damage.

Description of reference numerals: 10, nib groove, 20, nib, the 30, first locked groove, 40, snap close, 50, projection, 60, pen core, the 70, second locked groove, 80, the outer pen cap, 90, the interior pen cap.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.

The object of the utility model design is: by the pen cap in arranging movably in the pen cap outside, pen core is installed, can make pen core between use location and memory location, switch back and forth easily, and then protection pen core is difficult for sustaining damage.

Consult shown in Fig. 1, the utility model provides a kind of learning pen, comprise the outer pen cap 80, be located at the nib 20 of the outer pen cap 80 one end, with pen core 60, on nib 20, be provided with the nib groove 10 corresponding with pen core 60, wherein: the utility model is also provided with and can makes the axially movable interior pen cap 90 along the outer pen cap 80 in the pen cap 80 outside, pen core 60 is located to the interior pen cap 90 inner sides, and there is use location or memory location between the interior pen cap 90 and the outer pen cap 80, when the interior pen cap 90 is with the outer pen cap 80 during in use location, the end of pen core 60 is positioned at outer end through nib groove 10, can write, as shown in Figure 1, when the interior pen cap 90 is with the outer pen cap 80 during in memory location, the end of pen core 60 is positioned at the outer pen cap 80 inside, as shown in Figure 2.

Concrete, the inwall of the pen cap 80 is provided with the first locked groove 30, projection the 50 and second locked groove 70 from top to bottom successively outside, and is provided with at the outer wall of the interior pen cap 90 snap close 40 matching with the first locked groove 30 or the second locked groove 70; Now, when projection 50 is positioned at the first locked groove 30, the interior pen cap 90 is with the outer pen cap 80 in use location, and when projection 50 is positioned at the second locked groove 70, the interior pen cap 90 and the outer pen cap 80 are in memory location.The utility model makes snap close 40 on the interior pen cap 90 between the first locked groove 30 of the pen cap 80 and the second locked groove 70, switch back and forth to reach outside use or the protection of pen core 60 by the pen cap 90 in mobile.
