CN101670731A - Automatic pen - Google Patents

Abstract

The invention relates to an automatic pen, comprising an inner pipe, an inner barrel, a middle barrel, an outer barrel and a chuck, wherein the de-coring manner realizes de-coring by stopping the penwhen in use, and a user holds the outer barrel (5) and stops the pen tip so that the movement control of the pen core can be realized. The pen core is filled inside the middle barrel (4) while the traditional similar one is used, namely, the pen core and the top core (2) are filled in the same passage, thus causing the following two questions: firstly, if the pen core is filled from the tail part,the top core (2) must be pulled out; and secondly, the used pen core must be as thick as the top core (2). The invention solves such two problems that the top core (2) is not needed to pull out whilethe pen core is filled from the rear end of the pen. The used pen core can be thinner than the top core (2).

Description

From starting writing

(1) technical field:

The present invention relates to a kind of stationery, a kind of specifically from starting writing.

(2) background technology:

Knockout mode during use has realized a knockout, and the user holds urceolus (a 5) some nib, can realize the control of moving to pen core.

Similar product in the past are filled in middle tube (4) the inside to pen core in use, that is to say that a pen core and plunger tip (2) are filled in the same passage, and this has mainly produced two problems: 1. if load pen core from afterbody, must take out plunger tip (2).2. employed pen core must and plunger tip (2) etc. slightly.The present invention is directed to these two problems solves.When using, the user, needn't take out plunger tip (2) if load pen core from the rear end of pen.Pen core used in the present invention can be thinner than plunger tip (2).

(3) summary of the invention:

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

Interior pipe (10) is provided with cannelure.

Employed pen core is filled in the interior pipe (10).

Plunger tip (2) is provided with dop (3) and pawl (11).

Plunger tip (2) is enclosed within interior pipe (10) outside, and pawl (11) sees through the cannelure of interior pipe (10) and fixes the interior pen core of interior pipe (10).

Inner core (1) is provided with cannelure.

Inner core (1) is enclosed within plunger tip (2) outside.Dop (3) is stuck in the cannelure of inner core (1).

Middle tube (4) is provided with helicla flute.

Middle tube (4) is enclosed within inner core (1) outside.The cannelure that dop (3) sees through inner core (1) is stuck in the helicla flute of middle tube (4).

In the rotation of tube (4) can drive dop (3) and be moved along the cannelure of inner core (1), be moved thereby drive plunger tip (2), so realized moving of pen core.

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

Figure 16 is that embodiment 1 is with the design sketch after urceolus (5) vertical profile.Be from the state of starting writing when writing at this moment.

Figure 17 is that embodiment 1 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 18 is that embodiment 1 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 19 is that embodiment 1 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:

Embodiment 1:

Can establish nipper (6) and back tooth (7) at middle tube (4) during concrete enforcement, establish preceding apical tooth (8) and back apical tooth (9) at urceolus (5).

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 plunger tip (2) and inner core (1) in, move, thereby realize pen core mobile in interior pipe (10).

Plunger tip (2) can be fallen back on a tail when user uses, pawl (11) can open the interior pipe (10) of at this moment new pen core can being packed into from the rear end of pen by nature.Load pen core from the rear end of pen, 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 nib when user uses, pen core moves backward with respect to urceolus (5), and pen core moves drive plunger tip (2) and moves, tube (4) moved during plunger tip (2) drove, by the interaction between tooth and the apical tooth, this moves middle tube (4) is rotated, thereby has realized moving of pen core.
