CN201511669U - Automatic pen - Google Patents

Abstract

The utility model relates to an automatic pen, which includes a pen cylinder, an outer sleeve with a spiral groove, and a refill capable of being removed from the pen refill. The automatic pen has the advantage that the maximum using rate of the pen refill can be achieved.

Description

From starting writing

(1) technical field:

The utility model relates to a kind of stationery, and is a kind of specifically from starting writing.

(2) background technology:

The employed pen core of the utility model can be loaded from the tail end of pen.

Thereby mainly solved pen core and can't use wasting drawback fully.

(3) summary of the invention:

The utility model provides a kind of writing implement, needn't directly grip pen core again when the user is write.

Compare with existing writing implement, the problem that the utility model solves is to provide new knockout mode, the rotation knockout.And allow the user to load pen core from the tail end of pen.

This comprises chalk, pencil, wax crayon, rubber from the employed pen core of starting writing.

Pen container (1) is provided with cannelure, and urceolus (4) is provided with helicla flute, and urceolus (4) is enclosed within pen container (1) outside, and inner core (2) is contained in pen container (1) the inside, and inner core (2) is provided with dop (3).

The cannelure that dop (3) sees through pen container (1) is stuck in the helicla flute of urceolus (4), and rotation urceolus (4) can drive dop (3) and move along the cannelure of pen container (1), thereby it is mobile pen container (1) in to drive inner core (2).

Inner core (2) can drive pen core and move.

Dop (3) is scalable.

After dop (3) withdrawal, inner core (2) pen container (1) of can packing into also can take out in pen container (1).

Can be when the user uses this to start writing certainly by advancing of pen core being controlled in the rotation of urceolus (4) or being retreated.

This allows the user from starting writing, can load pen core from the front end of pen, also can load pen core from the rear end of pen.

The user loads pen core if inner core (2) is taken out from the rear end of pen in pen container (1), its advantage is to take out residual pen core, and residual pen core still can continue to use behind the new pen core of packing into, thereby reaches the best utilization rate of pen core.

(4) description of drawings:

Fig. 1 is from starting writing overall diagram.(1) is pen container among the figure, and (2) are inner cores, and (4) are urceolus.

Fig. 2 is all parts after taking apart.(1) is pen container among the figure, and (2) are inner cores, and (3) are dops, and (4) are urceolus.

Fig. 3 is the top vertical view of urceolus (4).

Fig. 4 is the sectional side elevation of urceolus (4).

Fig. 5 is the top vertical view of pen container (1).

Fig. 6 is the outside drawing of pen container (1).

Fig. 7 is the outside drawing of inner core (2).

(5) specific embodiment:

Can be when the user uses this to start writing certainly by advancing of pen core being controlled in the rotation of urceolus (4) or being retreated.

When using, the user loads pen core from the rear end of starting writing certainly if select, can not take out residual pen core, inner core (2) is taken out from the rear end of pen container (1), the new pen core of packing into from the rear end of pen container (1), the pen container (1) of again inner core (2) being packed into from the rear end of pen container (1), the cannelure that makes dop (3) on the inner core (2) see through pen container (1) snaps in the helicla flute of urceolus (4), at this moment can turn urceolus (4) with hand, urceolus (4) drives inner core (2) by rotation and advances in pen container (1), inner core (2) drives new pen core and advances, new pen core drives residual pen core and advances, and residual pen core can continue to use, thereby reaches the best utilization rate of pen core.

Claims (4)

1. start writing certainly for one kind, it is characterized in that: parts have pen container (1), inner core (2), dop (3), urceolus (4), and dop (3) is scalable.

2. according to claim 1 from starting writing, it is characterized in that: pen container (1) is provided with cannelure.

3. according to claim 1 from starting writing, it is characterized in that: inner core (2) is provided with dop (3).

4. according to claim 1 from starting writing, it is characterized in that: urceolus (4) is provided with helicla flute.
