The pen core 2, including pen core tube 13 and pen core head 14, the pen core head 14 are mounted on the front end of pen core tube 13, institute 13 center of pen core tube is stated equipped with inner hole 15, inner hole 15 is perfused with pen core oil, is equipped with oil seal groove, the oil in the front end of pen core tube 13 Oil sealing 16 is equipped in sealing groove, the oil sealing 16 includes epipharynx 17 and outer lip 18, card slot 19 is formd between epipharynx 17 and outer lip 18, The inner wall of epipharynx 17 is equipped with multi-stage sealed tooth lip 20, and the pen core head 14 includes mounting rod 21 and nib 22, the mounting rod 21 It is equipped with positioning ring 23, mounting rod 21 passes through the mounting hole 24 that multi-stage sealed tooth lip 20 is formed and positioning ring 23 is made to be fastened on pen core In the locating slot 26 of 25 inner wall of location hole of 13 front end of pipe；The top of the epipharynx 17 of the oil sealing 16 is centered around the week of mounting hole 24 Side is equipped with several flexible sheets 27, and several combinations of flexible sheet 27 form diaphragm seal 28, and the matching of diaphragm seal 28 seals installation Hole 24, so as to seal the leakage of pen core oil.

The bottom end of the oil sealing 16 is equipped with annular groove 29, and 22 top of nib of the pen core head 14 has annular protrusion 30, The annular protrusion 30 is embedded in annular groove 29.

The multi-stage sealed tooth lip 20 includes that upper combination lip 31 combines lip 32 under, and the upper combination lip 31 inclines including several Obliquely in the upper lip ring 33 being spaced apart, lower combination lip 32 include it is several diagonally downward in the lower lip ring being spaced apart 34, the upper lip ring 33 and lower lip ring 34 are mutually symmetrical.

The corrugated structure 35 of the outer peripheral surface of the outer lip 18 of the oil sealing 16；The outer peripheral surface of the epipharynx 17 is equipped with snap ring 36, the snap ring 36 is flushed with the top surface of epipharynx 17.

It makes an explanation below to the structural principle of the practice of the utility model pen:

The practice pen of the utility model, when in use, index finger, thumb, the middle finger of finger are matched respectively in the first groove 3 Pinch plate 6, the pinch plate 6 of the second groove 4, third groove 5, it is vertical between the first groove 3, the second groove 4 and third groove 5 The position of finger when the spacing in direction just matches correct holding-posture, so the pen holding posture of beginner can be corrected, and keeps Good writing habit.When hold a pen tension when, the huge power of pinching leads to 6 pressure-ram 7 of pinch plate, and the head of push rod 7 is taper, this Sample, excessive active force make push rod 7 squeeze spring 9, finally surmount the elastic force of spring 9, and electroconductive elastic sheet 10 is made to contact button electricity The anode in pond 11 makes the circuit of the anode of button cell 11, cathode one closure of formation of indicator light 12, button cell 11, this When, indicator light 12 is shinny, reminds practitioner to loosen, carries out accurate grip position.

In use, practice is easy to happen with pen and is dropped, and the pen core head 14 of pen core 2 is easiest to occur outside being exposed to Damage, the ball 37 in pen core head 14 after damage can not normally continue to roll on paper, write, so, the utility model Pen core 2 can use simple tweezers tool after damage, the firmly outside drawing of pen core head 14 be clamped, when the power of drawing surmounts When binding force between the positioning ring 23 of pen core head 14 and the locating slot 26 of location hole 25, pen core head 14 is drawn out pen core tube 13 Front end, as pen core head 14 is pulled out, several flexible sheets 27 on oil sealing 16 inwardly reset, and form diaphragm seal 28 and seal peace Hole 24 is filled, to prevent pen core oil from leaking after pen core head 14 is pulled out, the mounting rod 21 of new pen core 2 is then inserted into peace Dress hole 24 is simultaneously set up to positioning ring 23 blocks into locating slot 26, and in the process, mounting rod 21 squeezes flexible sheet 27, to make Flexible sheet 27 is fitted in the outer surface of mounting rod 21, cooperates the epipharynx 17 of oil sealing 16, plays comprehensive sealing function；Pen core First 14 22 position of nib has annular protrusion 30, and correspondence is fastened in the annular groove 29 of oil sealing 16, and pen core head 14 can be more Stablize, securely, when writing, stable writing experience can be brought.

The oil sealing 16 of the utility model, is divided into epipharynx 17 and outer lip 18, can be combined with pen core tube 13 it is stronger, Can more gluing, sealing pen core head 14, upper combination lip 31 and the lower setting for combining lip 32 replace the plug of pen core head 14, Better protective effect is played, the service life of oil sealing 16 is extended.

Practice provided by the utility model embodiment is described in detail with pen above, it is used herein specifically A example is expounded the principles of the present invention and embodiment, and the above embodiments are only used to help understand originally The revealed technical solution of utility model；At the same time, for those skilled in the art, based on the idea of the present invention, There will be changes in the specific implementation manner and application range, in conclusion the content of the present specification should not be construed as this reality With novel limitation.
