Specific embodiment:

The utility model preferred embodiment is elaborated with reference to the accompanying drawing.

The utility model provides a kind of teaching of Chinese pen, includes penholder 1, nib 2 and pen cap 3, pen cap front end Closed, rear end then offers pen cap opening 31, and the inside of pen cap is hollow, it is possible thereby to protruding into for pen tip is accommodated, thus When not having to pen, pen tip is protected by pen cap, pen tip is prevented to be bent or the pollution such as dust.Penholder rear end is close It closes, the inner hollow of penholder forms accommodating chamber, is formed with penholder opening 11 in the front end of penholder, penholder opening namely accommodates The opening of chamber is provided with rubber ring 4 in penholder opening, and when pen cap is set on penholder, which is clamped in pen cap Between the outer wall of inner wall and the penholder opening of opening, while the rubber plantation also utilizes the elasticity of itself to provide reaction force to penholder The inner wall of outer wall and the pen cap opening of opening, fixes so that both penholder and pen cap are realized, when needing to extract pen cap, pulls at It starts writing cap, so that the frictional force that pulling force is greater than rubber ring can pull out pen cap.

And the mode that nib is then connected through a screw thread rotates the end for being connected to penholder, specifically, in penholder opening Offer internal screw thread on wall, written then include sleeve 21 and pen tip 22, sleeve both ends have been respectively formed opening, and pen tip is threaded through institute It states in sleeve and the front-end and back-end of the pen tip each extends over outside the opening at sleeve both ends, be formed with band in sleeve rear end Externally threaded lug boss 211, the lug boss can be threaded on the inner wall of penholder opening, it is thus achieved that nib and penholder Rotation connection.The rear end of pen tip extends in the accommodating chamber inside penholder after the opening of sleeve, is formed in the rear end of pen tip Have thorn pipe 5 made of metal, be provided with pen core 6 in accommodating chamber, pen core be it is commercially available replace, be similar to ball The pen core of pen and gel ink pen, but unlike in the inner hollow of pen core form inking chamber, ink is filled in inking chamber, Pen core is closed at one end, and the other end is provided with core cap 61, and core cap is just to have covered the end for being located at pen core when leaving the factory, on core cap Ink hole 611 is offered, the fixed cork 7 in ink hole, the cork can be a unit of plastic, utilize in the initial state Cooperation of being full of is connected in ink hole, when metal prong pipe applies inward pressure to it, cork can be pierced through, so that golden Belong to thorn pipe to enter in inking chamber, ink is overflowed from the gap between metal prong pipe and ink hole in order to prevent, pierces the ruler of pipe It is very little to be adapted to as much as possible with the aperture of ink hole, i.e., close to the size with ink hole, since cork is fixed by interference fit In ink hole, when the moment that cork is pierced, the hole wall of ink hole can be from surrounding to contract, so as to be fitted in thorn pipe Outer wall on, realize to the closed of inking chamber.

It is formed with ink flow path (similar with pen in the prior art, therefore be not shown in the figure) in the inside of pen tip, The outlet 8 of ink flow path is offered on the side wall of pen tip front end, and the entrance of ink flow path is then provided with the piercing ink of thorn pipe The end of that one end of chamber, as a result, after piercing pipe and piercing through cork and enter inking chamber, ink in inking chamber can by ink flow path from It overflows outlet.In addition, being additionally provided with supporting block 9 in the front end of pen tip, a support can be played the role of to the tip of pen tip, Prevent pen tip by being bent after external impact.

It holds with a firm grip nib for the ease of user, it is circumferentially arranged on the outer wall of sleeve to have several recessed portions 212, finger Finger tip can protrude into recessed portion 212, and finger is preferably had an effect, and improve writing quality.It is provided on pen cap Pull rod 31, described pull rod one end are tilted outward by the side wall of the pen cap, can be pulled out pen cap from penholder convenient for user.

The above makes preferred embodiments of the present invention, does not depart from for those of ordinary skill in the art Under the premise of the utility model principle, several variations and modifications can also be made, these also should be regarded as the protection of the utility model Range.
