After the pen refill is arranged, the pen cap is compressed, a positioning stuck point is locked between a pen point and a circle A, the length of the pen cap is consistent with the length of the neutral pen cap in the present condition; the pen cap is stretched, the positioning stuck point is blocked between a circle B and a circle C, the pen cap is longer than the other pen cap in the present condition, the pen refill can be concealed, to reach the purpose of protecting the pen refill and avoiding pollution.

Description

The drawing neutral pen cap of pen core that protects
Affiliated technical field
The utility model relates to a kind of drawing neutral pen cap of pen core that protects.
Background technology
At present, the neutral pen cap great majority of selling on the market by the cap for brush and a body independently two parts form, this kind pen cap uses trouble and cap for brush part easily to lose.
Summary of the invention
In order to overcome the shortcoming that the above-mentioned pen cap uses trouble and cap for brush part easily to lose, the utility model provides a kind of drawing neutral pen cap of pen core that protects.
The technical scheme that its technical problem of solving the utility model adopts is: the interior pen cap one end is a nib, the other end be diameter less than nib at the bottom of the cylinder of diameter.The circle of three projections is set around cylinder outer wall---circle A, circle B, circle C.The circle C place the interior pen cap one end margin and a little more than the circle A and the circle B.Enclose between A, circle B, the circle C at a distance of suitable distance.Inboard, one section edge of the outer pen cap arranges the location stuck point of four projections.After the inside and outside pen cap connected, under the effect of certain external force, the location stuck point can move about between circle C and nib.The other end of the outer pen cap links to each other with screw thread with the pen core fixture.In the pen core fixture inner and outer ring is set, its internal diameter size is consistent with two kinds of Neutral ball-point for ball-point pen external diameters on the market.After pen core was installed, the compression pen cap, location stuck point were stuck between nib and the circle A, and this moment, this pen cap was consistent with other neutral pen cap length; The stretching pen cap, location stuck point are stuck between circle B and the circle C, and this moment, this pen cap was longer than other pens cap, can hide pen core, reached protection pen core and antipollution purpose.
The beneficial effects of the utility model are: need not add separately and have protection pen core and antipollution function with the cap for brush, and easy to use, simple in structure.

Fig. 2 is interior pen cap schematic diagram.
Fig. 3 is outer pen cap schematic diagram.
Pen core fixture schematic diagram during Fig. 4.
1. nibs among the figure, 2. in the pen cap, 3. circle A, 4. cylinder, 5. location stuck point, 6. circle B, 7. circle C, the 8. outer pen cap, 9. screw thread, 10. outer shroud encircles 12. pen core fixtures in 11..
Specific embodiments
In Fig. 1, circle C7 is squeezed into the outer pen cap 8 by stuck point 5 places, the inboard location of an end margin of the outer pen cap 8, thereby the interior pen cap 2 and the outer pen cap 8 are coupled together.Because circle C7 is a little more than circle A3 and circle B6, location stuck point 5 is difficult for skidding off circle C7, and under the effect of certain external force, location stuck point 5 can slip over circle A3 and circle B6, slides between nib 1 and the circle C7.The other end of the outer pen cap 8 is connected with pen core fixture 12 usefulness screw threads 9.
In Fig. 2, nib 1 and circle A3 be at a distance of about 2 millimeters, and circle A3 and circle B6 be at a distance of about 1 centimetre, and circle B6 and circle C7 stretch or the compression pen cap at a distance of about 2 millimeters, can make location stuck point 5 be stuck between circle B6 and the circle C7 or nib 1 and enclosing between the A3.
In Fig. 4, outer shroud 10 is from outside to inside slightly gradually little with interior ring 11 internal diameter sizes, and it is about respectively 7 millimeters and 4 millimeters, namely conform to two kinds of Neutral ball-point for ball-point pen external diameters selling on the market, thus the fixing pen core of this device.
