Abstract

The utility model discloses a dual-purpose self-cleaning pen sleeve, which is mainly composed of a sleeve body and a cleaning piston, wherein the sleeve body is in the shape of a hollow-out column, two ends of the sleeve body are respectively provided with an opening matched with the shape of a pen tube in the axial direction, the two ends of the sleeve body are communicated through the two openings, the cleaning piston is embedded in the sleeve body, and the outer wall of the cleaning piston clings to the inner wall of the sleeve body. The cleaning piston is movably embedded into a hollow-out cavity of the sleeve body, and the axis of the cleaning piston is in coincidence with that of the sleeve body. The pen sleeve is capable of effectively removing ink smudges remained in the pen sleeve, thereby avoiding the fact that hands of users are stained by the ink smudges which are transferred to the pen tube from a pen cap.

Description

The dual-purpose self-cleaning pen cap

Technical field

The utility model relates to a kind of stationery, is specifically related to a kind of dual-purpose self-cleaning pen cap.

Background technology

Traditional pen cap is the hollow structure of column; when pen (as free ink pens such as pen or signature pens) inserts the pen cap or extracts in the process of the pen cap; the as easy as rolling off a log inwall of being infected with the pen cap of ink marks on the pen; residual ink marks can go on the shaft of a writing brush on the pen cap inwall like this, and allows user's hand when using next time can adhere to ink marks.

The utility model content

Technical problem to be solved in the utility model provides a kind of dual-purpose self-cleaning pen cap, and it can effectively eliminate the ink marks that residues in the pen cap.

For addressing the above problem, a kind of dual-purpose self-cleaning pen cap that the utility model is designed comprises the body of a hollow columnar, and the axial two ends of described body respectively offer an opening that matches with shaft of a writing brush shape, and these 2 openings connect the two ends of body; The cleaning piston that is with a cylindricality is also established in the inside of above-mentioned body, and the inwall of this cleaning piston outer wall and body fits, and the cleaning piston activity is nested in the hollow cavity of body, and the dead in line of the axis of cleaning piston and body.

For the ease of the embedding of nib, the axial two ends of the described cleaning piston of such scheme preferably respectively are provided with an embedded groove that caves in vertically.

In the such scheme, the center of embedded groove preferably is positioned on the axis of cleaning piston.

In order to improve the adsorptivity of cleaning piston, the described cleaning piston of such scheme preferably adopts plastic material to make.

Deviate from for fear of cleaning piston from body, preferably be provided with anti-drop convex clip near the inwall the described body both ends open of such scheme.

Preferably also be fixed with a two-way pen button on the lateral wall of the described body of such scheme.

Compared with prior art, the utlity model has following characteristics:

1, the body two ends of the pen cap are all established opening and are gone into for penholder, and portion sets movable cleaning piston within it; When an end from body inserted, cleaning piston was pushed into the other end of body by nib like this; Pen alternately inserts from the two ends of body, promotes cleaning piston and promotes repeatedly in the inside of body, can reach the effect of cleaning pen cap inwall pen and ink, thus avoid ink marks by the cap for brush go to allow on the shaft of a writing brush user in use hand adhere to ink marks;

2, body both ends open inboard is provided with anti-drop convex clip and limits built-in cleaning piston, deviates from body in the process of two-way ejection to prevent cleaning piston;

3, but the pen button on the pen cap shell also is designed to two use, no matter pen inserts the pen cap from which head, can be inserted on the pocket as conventional pen like this.

Description of drawings

Fig. 1 is the schematic diagram of a kind of dual-purpose self-cleaning pen cap of the utility model;

Fig. 2 is the parts packing figure of Fig. 1.

Indicate among the figure: 1, body; 1-1, anti-drop convex clip; 2, cleaning piston; 2-1, embedded groove; 3, pen button.

The specific embodiment

Referring to Fig. 1, be a kind of dual-purpose self-cleaning pen cap of the utility model, it mainly is made up of body 1 and cleaning piston 2.Wherein body 1 is hollow columnar, and the axial two ends of this body 1 respectively offer an opening that matches with shaft of a writing brush shape, and these 2 openings connect the two ends of body 1.Cleaning piston 2 is nested in the body 1, and the inwall of cleaning piston 2 outer walls and body 1 fits.Cleaning piston 2 activities are nested in the hollow cavity of body 1, the axis of cleaning piston 2 and the dead in line of body 1.Dual-purpose self-cleaning pen cap outward appearance is as a body 1 that connects in opposite directions, and pen can at will insert the built-in cleaning piston 2 that can move at body 1 two ends from two.After taking pen, it is residual that the inwall of body 1 often has ink marks, at this moment pen inserted from body 1 other end, just body 1 built-in cleaning piston 2 can be extruded onto an end that leaves ink marks.Replace like this from the two ends insertion pen of the body 1 of body 1, can impel cleaning piston 2 in body 1, to promote repeatedly, the friction of the outer wall by cleaning piston 2 and the inside of body 1 is adsorbed on the ink marks on the pen cap on the cleaning sleeve, can reach the purpose of cleaning pen cap inwall.

In order to allow pen better embed in the pen cap, simultaneously also in order better to drive cleaning piston 2 moving in body 1, the axial two ends of described cleaning piston 2 also respectively are provided with an embedded groove 2-1 who caves in vertically, and on the axis that is centered close to cleaning piston 2 of this embedded groove 2-1.Pen is in the process of inserting the pen cap like this, and its nib can snap in this embedded groove 2-1; And when pen in extracting the process of the pen cap, cleaning piston 2 just can be with extracting of beginning to write and retreat to the wherein end of body 1.Cleaning piston 2 of the present utility model can adopt as the material with absorption property to be made, and makes as materials such as hard foam, silica gel or plastic cement.And in the utility model preferred embodiment, described cleaning piston 2 adopts plastic material to make.The cleaning piston 2 of plastic cement quality can single injection-molded, and has certain toughness; So not only be convenient to produce but also can resist pushing repeatedly of nib and indeformable.

Deviate from 1 for fear of cleaning piston 2 from body, also be provided with anti-drop convex clip 1-1 near the inwall described body 1 both ends open.In the utility model preferred embodiment, described anti-drop convex clip 1-1 is 3 small embossments, and these 3 projectioies are distributed in the opening inboard of body 1, is used to block movable built-in cleaning piston 2.In addition, be fixed with a two-way pen button 3 on the lateral wall of described body 1, use, no matter pen inserts the pen cap from which head, can be inserted on the pocket like this as conventional pen but pen button 3 is designed to two.
