Description

Portable pen

The utility model relates to a kind of pen.

People often wish to carry ball pen short and small, comfortable, easy to use or pencil, foam pen etc. are standby when going out.Existing a kind of common short type ball pen has the pen cap and pen core, and the pen cap is sheathed on the pen core front end, and the pen cap and pen core match.This kind pen in fact still is the structure of common office with lettering pen, has only chosen less size on length.Like this, though its short and small profile helps carrying, when writing, often give uncomfortable sensation because of it is too short and small with it.Simultaneously and since when collection its pen core only can partly be inserted in the pen cap, do not maximally utilise space in the pen cap, so the handwriting length during its collection is still longer comparatively speaking.So above-mentioned existing pen exists defective.

The purpose of this utility model provide a kind of volume small and exquisite, write comfortable portable pen.

Portable pen of the present utility model has the pen cap and pen core, and the pen cap and pen core match.Axially offer the chute that runs through wall cover sidewall especially at the pen cap upper edge pen cap, be provided with lateral positioning groove at this chute wall.Pen core is arranged in the pen cap, and the pen core front end points to pen cap opening.Be provided with the protruding slide block to pen cap sidewall that can embed lateral positioning groove on the pen cap at the pen core end, this slide block matches with described chute.In the utility model, by stirring the terminal slide block that is provided with of pen core, slide in the chute that makes it on the pen cap, to be provided with, can drive pen core and slide before and after in the pen cap, and then make the pen core front end stretch out or withdraw from pen cap opening part.When collection, can make pen core in the pen cap, be retracted state.When needs are write, stir slide block the pen core front end is stretched out from pen cap opening part, and slide block is embedded lateral positioning groove, avoid slide block to continue to endwisely slip along the pen cap, can form the pen that has sufficient length, is convenient to write.Write finish after, slide block is withdrawed from lateral positioning groove, allow it drive pen core and return collection in the pen cap.In the utility model, can one or more lateral positioning grooves axially be set at upper edge, the chute path pen cap.When a plurality of lateral positioning groove is set, embed different detents by making slide block, can regulate the length of pen easily.In addition, the pen core of setting can be refill for ball-point pen, also can be pencil or foam pen core.

Portable pen of the present utility model is compared with aforementioned existing similar pen, because pen core can all be regained the pen cap, utilizes space in the pen cap fully, thereby the length of pen is shortened when collection to greatest extent.When writing, after pen core stretched out the location in the pen cap, the pen core and the pen cap fully, were stably realized splicing, and reaching is enough to comfortable length of writing.Therefore, portable pen of the present utility model has the advantages that volume is small and exquisite, be convenient to write.

Content of the present utility model is further described with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is the pen cap structure chart of portable pen among the embodiment.

Fig. 2 is the pen core structure chart.

Fig. 3 is the right view of pen core.

Fig. 4 is the elongation state figure of portable pen.

Fig. 5 is the collecting state figure of portable pen.

Shown in Fig. 1～5, the portable pen among the embodiment has the pen cap 1 and ball pen 5, and the pen cap and pen core match.Axially offer the chute 2 that runs through wall cover sidewall at the pen cap upper edge pen cap, on the sidewall of the both sides at these chute two ends, be respectively arranged with transverse concave groove 3,4.Pen core 5 is arranged in the pen cap 1, and pen core front end 6 points to pen cap opening 12.Be provided with protruding slide block 8 to the pen cap at the pen core end, this slide block is fixed in the top of reed 7, and the pen core end is fixed in the bottom of reed 7, and the elastic top thrust of reed is pointed to pen cap sidewall.Have contraction section 9 and the section of widening 10 respectively in the upper and lower of slide block 8, this contraction section 9 matches with chute 2, and the section of widening 10 matches with transverse concave groove 3,4.For ease of carrying, on the outer wall of the pen cap 1, be set with and hang tag 11, this opposite face that hangs tag with the pen cap is a toothed surface, this helps preventing losing when handwriting from hanging attached carrying.When portable of use present embodiment, by stirring slide block 8, its contraction section 9 is slided in chute 2, can drive pen core 5 and in the pen cap 1, slide.When slide block 8 slid into transverse concave groove 3 places of chute left end, under the pushing tow of reed 7, the section of widening of slide block 10 embedded transverse concave groove 3 location, and the portable pen of this moment is the elongation state of being convenient to write.When need are collected, press sliding block 8, the embedding state that the section of widening 10 is removed groove 3, and promote slide block 8 immediately, make slide block proceed to the location, transverse concave groove 4 places (its locate mode is to preceding similar) of chute right-hand member along chute.In this process, pen core also moves with slide block, finishes the collection process.

The left and right end transverse concave groove 3,4 of chute in the present embodiment also can only be opened in a side sidewall of chute.Corresponding, the section of widening of slide block 10 also should suitably be revised, and the groove that makes it and be arranged at chute one side adapts.In addition, as new embodiment, also being connected of pen core and slide block can be connected to change into by elastic spring and be rigidly connected.When slide block slides into the transverse concave groove place and when needing the location, only need laterally stir slide block, make slide block laterally embed transverse concave groove, can prevent limited slip block voluntarily along the chute axially-movable, thereby realize the location.In this process, with the rigidly connected pen core of slide block also along with the horizontal embedding of slide block in the pen cap rotating certain angle.In an embodiment after this, the unnecessary setting of the section of widening 10 of slide block bottom among the former embodiment.
