CN201501199U - Autopen - Google Patents

Abstract

The utility model discloses an autopen belonging to a writing instrument. The structure thereof comprises an outer barrel, a middle barrel, an inner tube and a top core, wherein a chuck and a claw are arranged on the top core. Longitudinal grooves are respectively arranged on the inner tube and the middle barrel. A spiral groove is arranged on the outer barrel. The top core is sheathed outside the inner tube, the middle barrel is sheathed outside the top core, and the outer barrel is sheathed outside the middle barrel. The decoring mode is rotary decoring. When the autopen is used, a pen core can be packed inside from the rear end of the autopen. The autopen has the advantage of achieving the optimal usage rate of the pen core. Compared with the existing like products, the autopen solves the problem that the top core needs to be as thick as the used pen core, thereby leading the pen core used by the autopen to be considerably thin.

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 utility model can be realized moving of pen core by the rotation to urceolus (6) in use.

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 utility model solves at these two problems just.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:

The utility model discloses a kind ofly from starting writing, belong to a kind of writing appliance.

The knockout mode is the rotation knockout.

During use, the user can load pen core from the rear end of pen, and its advantage is the best utilization rate that reaches pen core.

Compare with similar product in the past, the utility model solved plunger tip must and thick problem such as employed pen core, thereby make the employed pen core of the utility model can be very thin.

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

Interior pipe (1) is provided with cannelure.

Employed pen core is filled in the interior pipe (1).

Plunger tip (2) is provided with dop (3) and pawl (5).

Plunger tip (2) is enclosed within interior pipe (1) outside, and pawl (5) sees through the cannelure of interior pipe (1) and fixes the interior pen core of interior pipe (1).

Middle tube (4) is provided with cannelure.

Middle tube (4) is enclosed within plunger tip (2) outside.Dop (3) is stuck in the cannelure of middle tube (4).

Urceolus (6) is provided with helicla flute.

Urceolus (6) is enclosed within middle tube (4) outside.The cannelure that dop (3) sees through middle tube (4) is stuck in the helicla flute of urceolus (6).

The cannelure that the rotation of urceolus (6) can drive tube (4) in dop (3) edge is moved, and is moved thereby drive plunger tip (2), so realized moving of pen core.

(4) description of drawings:

Fig. 1 is the overall appearance front view.(1) is interior pipe among the figure, and (4) are middle tubes, and (6) are urceolus.

Fig. 2 is the positive side figure of overall appearance 90 degree.(1) is interior pipe among the figure, and (4) are middle tubes, and (6) are urceolus.

Fig. 3 removes urceolus (6) front view afterwards.(1) is interior pipe among the figure, and (2) are plunger tips, and (3) are dops, and (4) are middle tubes.

Fig. 4 removes urceolus (6) the positive side figure of 90 degree afterwards.(1) is interior pipe among the figure, and (3) are dops, and (4) are middle tubes.

Fig. 5 removes urceolus (6) 45 degree side views afterwards.(1) is interior pipe among the figure, and (2) are plunger tips, and (3) are dops, and (4) are middle tubes.

Fig. 6 is the perspective view of urceolus (6).

Fig. 7 is the front appearance figure of urceolus (6).

Fig. 8 is the sectional side elevation of urceolus (6).

Fig. 9 is a middle tube (4).

Figure 10 is interior pipe (1).

Figure 11 is plunger tip (2).(3) are dops among the figure, and (5) are pawls.

(5) specific embodiment:

Can be fixed with each other interior pipe (1) and middle tube (4) during concrete enforcement at the front end of pen.

When using, the user can realize the control of moving by rotation to urceolus (6) to pen core.

The user can select to load pen core from the front end of pen.

When the user selects when pen core is loaded in the rear end of pen, can be by rotation to urceolus (6), plunger tip (2) is shifted onto the tail end of middle tube (4), and at this moment pawl (5) can open by nature, the user just can be from the rear end of pen toward interior pipe (1) in the employed pen core of filling.

The advantage of loading pen core from the rear end of pen is, can not 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.

Claims (1)

1. start writing certainly for one kind, it is characterized in that: parts have interior pipe (1), plunger tip (2), dop (3), middle tube (4), pawl (5), urceolus (6), interior pipe (1) is provided with cannelure, plunger tip (2) is provided with dop (3) and pawl (5), middle tube (4) is provided with cannelure, and urceolus (6) is provided with helicla flute, and plunger tip (2) is in interior pipe (1) outside, middle tube (4) is in plunger tip (2) outside, and urceolus (6) is in middle tube (4) outside.
