CN201501201U - Autopen - Google Patents

Abstract

The utility model relates to an autopen the structure of which comprises an inner barrel provided with a longitudinal groove, a middle barrel provided with a spiral groove, an outer barrel provided with front and rear teeth and an inner core which can be taken out from a pen barrel. The autopen has the advantage that the optimal usage rate of a pen core 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:

Thereby mainly having solved pen core, the utility model can't use wasting drawback fully.

Knockout mode of the present utility model has realized a knockout.Hold urceolus during use, a some nib can go out pen core automatically.

(3) summary of the invention:

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

Inner core (1) is provided with cannelure, and middle tube (4) is provided with helicla flute, and middle tube (4) is enclosed within inner core (1) outside, and inner core (2) is contained in inner core (1) the inside, and inner core (2) is provided with dop (3).

The cannelure that dop (3) sees through inner core (1) is stuck in the helicla flute of middle tube (4), and the rotation of middle tube (4) can drive dop (3) and be moved along the cannelure of inner core (1), is moved in inner core (1) thereby drive inner core (2).

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

Dop (3) is scalable, and after dop (3) withdrawal, inner core (2) inner core (1) of can packing into also can take out in inner core (1).

Middle tube (4) is provided with nipper (6) and back tooth (7), and urceolus (5) is provided with preceding apical tooth (8) and back apical tooth (9).

Urceolus (5) is enclosed within the outside of middle tube (4).

When the user makes urceolus (5) when moving forward, the back apical tooth (9) of urceolus (5) comes in contact with the back tooth (7) of middle tube (4), and this contact rotates middle tube (4).

The user moves urceolus (5) backward then, and the preceding apical tooth (8) of urceolus (5) comes in contact with the nipper (6) of middle tube (4), and this contact rotates middle tube (4).

In the rotation of tube (4) drive inner core (2) and inner core (1) in, move, thereby realize pen core mobile in inner core (1).

(4) description of drawings:

Fig. 1 is from starting writing overall appearance figure.(1) is inner core among the figure, and (2) are inner cores, and (5) are urceolus.

Fig. 2 is all parts after taking apart.(1) is inner core among the figure, and (2) are inner cores, and (3) are dops, and (4) are middle tubes, and (5) are urceolus.

Fig. 3 is the outside drawing of urceolus (5).

Fig. 4 is the sectional side elevation of urceolus (5).Can see preceding apical tooth (8), back apical tooth (9) after cutting open.

Fig. 5 is the outside drawing of middle tube (4).(6) are nippers among the figure, and (7) are the back teeth.

Fig. 6 is the perspective view of middle tube (4).

Fig. 7 is the sectional side elevation of middle tube (4).(6) are nippers among the figure, and (7) are the back teeth.

Fig. 8 is the outside drawing of inner core (1).

Fig. 9 is the perspective view of inner core (1).

Figure 10 is the outside drawing of inner core (2).(3) are dops among the figure.

Figure 11 is with the design sketch after urceolus (5) vertical profile.Be from the state of starting writing when writing at this moment.

Figure 12 is with the design sketch after urceolus (5) vertical profile.Be the state of urceolus (5) when moving forward at this moment,

Back apical tooth (9) and back tooth (7) come in contact, and middle tube (4) will be rotated.

Figure 13 is with the design sketch after urceolus (5) vertical profile.Be the state of urceolus (5) when mobile backward at this moment,

Preceding apical tooth (8) and nipper (6) come in contact, and middle tube (4) will be rotated.

Figure 14 is with the design sketch after urceolus (5) vertical profile.Be urceolus (5) state during mobile end backward at this moment, middle tube (4) rotates.

(5) specific embodiment:

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.

Can put a pen core when user uses, pen core moves backward with respect to urceolus (5), and pen core moves drive inner core (2) and moves, and tube (4) moved during inner core (2) drove, and this moves middle (4) are rotated, thereby has realized moving of pen core.

Claims (1)

1. start writing certainly for one kind, it is characterized in that: parts have inner core (1), inner core (2), dop (3), middle tube (4), urceolus (5), nipper (6), back tooth (7), preceding apical tooth (8), back apical tooth (9), inner core (1) is provided with cannelure, inner core (2) is provided with dop (3), dop (3) is scalable, middle tube (4) is provided with helicla flute, middle tube (4) is provided with nipper (6) and back tooth (7), urceolus (5) is provided with preceding apical tooth (8) and back apical tooth (9), inner core (1) is in inner core (2) outside, middle tube (4) is in inner core (1) outside, and urceolus (5) is in middle tube (4) outside.
