Abstract
An automatic nib-protection pen comprises a cartridge (1), a spring (7) and a pen cap (2); a sliding table (6) which is integrated with the cartridge is arranged at the front part of the cartridge (1); a pair of telescopic press blocks (5) are arranged on the pen cap (2), corresponding to the position of the sliding table (6) of the cartridge. The sliding table (6) is a conical lug; the front end surface of the lug is vertical to the axis of the cartridge. A spring seat (8) vertical to the middle axis is arranged inside the front end of the pen cap (2); the spring (7) is sleeved outside the cartridge (1) and between the spring seat (8) and sliding table (6). The press blocks (5) are embedded in a slide channel (4) which is arranged on the pen cap (2) and is vertical to the middle axis and are movably matched with the slide channel; the external end face each press block (5) is an arc surface parallel to the side wall of the pen cap. The utility model achieves automatic nib protection without special nib protection operations and is applied to gel-ink pens and ball-point pens.
Description
Technical field
The utility model relates to stationery, is a kind of pen that can protect nib automatically specifically.
Background technology
Nib be one-pen most important also be the part of most fragile, just can't use in case nib damages pen.Pen cap of present general use is protected nib, and ball pen generally need be pressed the button of regaining nib, but often people can forget the operation that these protect nibs, and the pen cap also is easy to lose, thereby makes nib lose protection, faces impaired danger.
Summary of the invention
The purpose of this utility model provides a kind of special operational motion that need not, and promptly can protect the pen of nib automatically.
The pen of described automatic protection nib comprises pen core 1, spring 7 and the pen cap 2, it is characterized in that: described pen core 1 front portion is provided with a slide unit 6 with pen core 1 one; Described slide unit 6 is a conical protrusions, the front end surface of projection and pen core axis normal or acutangulate introversion, its conical surface smooth surface with pen core 1; The described pen cap 2 is provided with a pair of scalable briquetting 5 in slide unit 6 conical surface positions of corresponding pen core.The front end inside of the described pen cap 2 is provided with the spring platform 8 of a circle and pen core axis normal, and spring 7 is enclosed within outside the pen core 1, between spring platform 8 and slide unit 6.Described scalable briquetting 5 is embedded on the pen cap 2 in the slideway 4 that be provided with and the pen core axis normal and movable with it cooperations, and the outer face of scalable briquetting 5 be and the cambered surface of pen cap parallel sidewalls, and its outside can be with one and enclose rubber and hold and overlap 3.
The utility model has been realized the automatic protection of nib with structure cleverly, and need not special protection nib operation, is applicable to gel ink pen, ball pen and the various pen that has pen core.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: the 1-pen core, the 2-pen cap, 3-rubber is held cover, 4-slideway, the scalable briquetting of 5-, 6-slide unit, 7-spring, 8-spring platform.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified: the pen of automatic protection nib as shown in fig. 1 is characterized in that: described pen core 1 front portion is provided with a slide unit 6 with pen core 1 one, and slide unit 6 and pen core 1 one-shot forming are made; The position of slide unit 6 is finger pen griping position when writing; The described pen cap 2 is provided with a pair of scalable briquetting 5 in slide unit 6 conical surface positions of corresponding pen core 1.
Described slide unit 6 is a conical protrusions, and conical protrusions is a symmetry axis with the axis of pen core 1, front end surface that this is protruding and pen core 1 axis normal or acutangulate introversion, its conical surface smooth surface with pen core 1.This slide unit 6 plays the effect of spring 7 restriction ends and guiding sliding surface simultaneously; and make pen core 1 when slide unit 6 is subjected to 5 compressings of scalable briquetting; whole pen core 1 is to front slide; therefore nib stretches out outside the pen cap 2; for can normally writing state, and after pressure cancels, be subjected to the back stretch effect of spring 7; pen core 1 whole back is sliding, and therefore nib is protected in the withdrawal pen cap 2.
The front end inside of the described pen cap 2 is provided with the circle spring platform 8 vertical with the axis, and spring 7 is enclosed within outside the pen core 1, between spring platform 8 and slide unit 6.Be subjected to the effect of spring 7, pen core 1 has been realized automatic retraction, has promptly protected nib automatically.
Described scalable briquetting 5 be embedded on the pen cap 2 be provided with the vertical slideway 4 in axis in and movable with it cooperations, the outer face of scalable briquetting 5 be and the cambered surface of pen cap parallel sidewalls, its outside can be with one and enclose rubber and hold and overlap 3.The shape of the inner face of scalable briquetting 5 can not limit, and during the pressure of finger, scalable briquetting 5 front ends inwardly move, and slide unit 6 is produced pressure when scalable briquetting 5 is subjected to writing, and slide unit 6 and pen core 1 one travel forward.The whole pen cap 2 is with rubber and holds cover 3 at scalable briquetting 5 places, so that the feel that holds a pen is steady, and can prevent dust.
As seen, the pen of protecting nib automatically is as long as holding scalable briquetting 5 positions, and nib promptly can be overhanging, so finger pinches this position when writing, nib is simultaneously overhanging; Nib can bounce back automatically when loosing one's grip.
Claims (3)
1. the automatic pen of protection nib comprises pen core (1), spring (7) and the pen cap (2), it is characterized in that: described pen core (1) front portion is provided with a slide unit (6) with pen core (1) one; Described slide unit (6) is a conical protrusions, the front end surface and pen core (1) axis normal of projection; The described pen cap (2) is provided with a pair of scalable briquetting (5) in slide unit (6) conical surface position of corresponding pen core (1).
2. the pen of automatic protection nib according to claim 1 is characterized in that: the front end inside of the described pen cap (2) is provided with the spring platform (8) of a circle and pen core (1) axis normal, and spring (7) is enclosed within outside the pen core (1), is positioned between spring platform (8) and the slide unit (6).
