Abstract
The present invention relates to the technical field of a pen, which is designed in order to simplify a structure. A telescopic pen comprises an upper pipe outer sleeve, a lower pipe inner column and a cartridge, wherein the lower pipe inner column is connected with the inner part of a middle cavity of the upper pipe outer sleeve in the mode of insertion. The present invention is characterized in that the upper pipe outer sleeve is provided with the middle cavity of which the cross section is rectangular, and a cuboid is correspondingly arranged in the lower pipe inner column. The cuboid is provided with a telescopic locking device which is matched with a plurality of positioning holes on the surface of the upper pipe outer sleeve, a spring is supported between the top end of the cuboid and the top end of the middle cavity of the upper pipe outer sleeve, the lower pipe inner column is also provided with a cavity, and the inner part is provided with the cartridge and is screwed and connected with a pen cap. The present invention has the advantages of simple structure, steady locking and easy use; the present invention is suitable for being extensively applied by people for study.
Description
Technical field
The present invention relates to the especially flexible pen technology field of pen in the stationery.
Background technology
Pen is the instrument that be unable to do without in people's learning life in the stationery, and conventional pen is fine long, and its shortcoming is to account for than large space, is not easy to carry.The someone designs telescopic pen for this reason, it as application number 95219003.6 Chinese patent " a kind of concertina type penholder ", it is made up of nib pipe and some telescoping tubes, radially have the hole clipping of symmetry in the inner of pipe, insert card and card pin in the hole clipping, cover one spring also has bayonet socket, with the motion of control valve on the card in the pipe.Its shortcoming structure is complicated, and the penholder that will firmly stretch during use just can make penholder extend, and on the other hand, in the process of writing, might overexert, and the penholder compression is shortened, and influences people and uses easily.
Summary of the invention
Technical problem to be solved by this invention provide a kind of simple in structure, locking is firm, be convenient to the flexible pen of production and assembly.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this flexible pen includes the pipe overcoat, under manage inner prop, pen core, under manage inner prop and be plugged in the pipe overcoat middle cavity, it is characterized in that it is rectangular middle cavity that the pipe overcoat has the cross section, corresponding buried pipe inner prop one end also is the rectangular cuboid in cross section, cuboid is provided with the elastic locking device with a plurality of locating hole couplings of last pipe sleeve surface, be supported with spring between cuboid top and the last pipe overcoat middle cavity top, under manage inner prop and also have cavity, interior dress pen core, a mouth again has been threaded.
Above-mentioned elastic locking device is that cuboid has the hole, and puts little spring, is pressed with the projection dop again;
Above-mentioned elastic locking device is that cuboid has the hole, and built-in flexure strip is pressed with the projection dop again.
Compared with prior art, the invention has the advantages that: this flexible pen, simple in structure, be convenient to production and assembly, and when using one by the projection dop, pen core can eject automatically, so very convenient to use, the locking device locking is also more firm, be difficult for making pen to overexert and cause flexible phenomenon, whole flexible pen compress its volume less, also be easy to carry.

The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, this flexible pen includes and manages overcoat 2, manages inner prop 8, pen core down; Under manage inner prop and be plugged in the pipe overcoat middle cavity, it is that rectangle is preferably foursquare middle cavity that last pipe overcoat has the cross section, corresponding buried pipe inner prop one end is that rectangle is preferably square cuboid 7 for the cross section also, cuboid is provided with the elastic locking device with a plurality of locating hole 3 couplings of last pipe sleeve surface, this locking device can be and has hole 5 on the cuboid, built-in little spring 4 or flexure strip, be pressed with projection dop 6 again, be supported with spring 1 between cuboid top and the last pipe overcoat middle cavity top, under manage and also have cavity in the middle of the inner prop, interior dress pen core, the mouth 9 that has been threaded again, going up pipe overcoat locating hole number preferably is 2-3.
Claims (5)
