Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
The pen of fountain pen nib telescopic protection as shown in Figure 1 to 9, comprises pen item, cap part, pen corePart and penholder.
Cap parts: form cap by the pen cap 1, for the protection of nib. The profile of the pen cap is the head of rabbit,More lovely, be vulnerable to the welcome of women and children population.
Although in the present embodiment can by rotation by pen core parts retraction penholder, nib with flowAir contact still can make evaporation of ink, and therefore cap parts still need.
Pen core parts: formed by nib 2, water receiver 5, pen item 4 and muffler 7 and skin courage 9 successively.
Water receiver 5 is positioned at pen item 4, and pen 4 inwall coordinate water receivers 5 to make ink concentrate on water receiver 5And in gap between pen item 4 inwalls; Secondly, on pen item 4, band is useful on matching thread, can be by pen coreParts tightly be fixed on penholder 8 inside.
Penholder parts: formed by point cover 3, screw rod 6, penholder 8 and tail cap 10. Point cover 3 is for fixingNib 2.
Screw rod 6 is arranged between tail cap 10 and pen item 4, and screw rod 6, comprises threaded rod 61 and limited post62, threaded rod 61 is provided with external screw thread 610, threaded rod 61 and the one-body molded setting of limited post 62, spiralBar 6 fixes with the outer wall of pen item 4.
On tail cap 10, being provided with tail keyholed back plate 100, as shown in Figure 3, is once penholder 8, tail control from outside to insidePipe 100 and threaded rod 61; Tail keyholed back plate 100 is between penholder 8 and threaded rod 61, in tail keyholed back plate 100Wall is provided with the internal thread 101 coordinating with external screw thread 610.
Limited post 62 is cylindric, and sidewall surfaces is provided with chute 620, the axle of chute 620 directions and penholder 8The heart is identical, and the inwall of penholder 8 is provided with the slide block 80 coordinating with chute. Slide block coordinates with chute, restrictionThe rotation of screw rod 6, in the time that tail cap 10 drives on screw rod 6 that threaded rod 61 rotates, screw rod 6 only canMove up and down.
Screw rod fixes with a pen outer wall, and then drives flexible up and down in penholder inside of pen core parts, reachesTo the object of protection nib.
Limited post 62 sidewalls are provided with totally 4 sliding groups, and 4 sliding groups are relative between two, the angle between adjacent sliding groupDegree difference is 90 °, and each sliding group is made up of 2 chutes 620, and the differential seat angle of interior two chutes 620 of sliding group is littleIn 45 °, the slide block 80 of penholder 8 inwalls is corresponding with chute 620.
The position of the slip of screw rod 6 is concentrated in 4 relative directions, and sliding process is more fluent.
The outer wall of tail keyholed back plate 100 is also provided with position limiting convex ring 102, and penholder 8 inwalls are provided with for position limiting convex ring 102 joinsThe limited ring groove closing. Position limiting convex ring 102 is provided with towards one end of pen item 4 and snaps in spacing for position limiting convex ring 102The transition cambered surface of annular groove.
Set up after position limiting convex ring 102, can make position-limiting action more obvious, replace original clamping type rotation,Make spacing safer reliably, avoid tail cap to deviate from, transition cambered surface is to facilitate position limiting convex ring to snap in limited ring grooveIn.
The above makes preferred embodiment of the present utility model, for the person of ordinary skill of the artDo not depart under the prerequisite of the utility model principle, can also make some modification and improvement, these also should be considered asProtection domain of the present utility model.
