Abstract

The utility model discloses an automatic needle tube pen, which comprises a hollow pen holder, a spring, a sandwich hand, a press cap, a hollow ink tube, a sandwich tube, a piston, an ink controlling core, a pen head and a pen core, wherein the sandwich hand, the spring and the press cap are successively arranged in the inner cavity of the open holder in a sliding mode; the outer end of the press cap is arranged at the outer side of one end of the pen holder; the ink tube is arranged at the other end of the pen holder; the sandwich tube is arranged on the sandwich hand in a movable and clamping mode; one end of the sandwich tube is arranged in the inner cavity of the pen holder, and the other end of the sandwich tube is placed in the inner cavity of the ink tube; the piston is arranged on the sandwich tube in the inner cavity of the sandwich tube; the ink controlling core is arranged at the port of the top of the ink tube; the pen head is arranged in the ink controlling core; the pen core is arranged in the sandwich tube; the top of the pen core penetrates through the inner cavity of the ink tube and the pen head in turn; the top of the pen core is arranged at the outer side of the pen head. The automatic needle tube pen has the advantages that the automatic needle tube pen is convenient and high in utilization rate, the problem that the pen head of the needle tube pen is abraded can be well solved, and the pen core can be outwardly knocked out, so the utilization rate of the pen core is improved, the evaporation of the pen ink is prevented, ink can be filled in the ink tube, and the automatic needle tube pen can be repeatedly used.

Description

The automatic needle tube pen

Technical field:

The utility model relates to a kind of drawing pen, relates in particular to a kind of automatic needle tube pen.

Background technology:

Existing drawing pen, nib is thinner, limited length, very easily wearing and tearing, in the later stage use procedure, easily cause the inconsistent situation with scratching paper of line weight of pen to occur, do not use for a long time and can cause pen and ink easily dry, can not recycle, service life is shorter, causes to a great extent the waste of pen.

The utility model content:

The purpose of this utility model is to provide a kind of convenience, the automatic needle tube pen that utilization rate is high.

The utility model is implemented by following technical scheme: the automatic needle tube pen, and it comprises penholder, spring, sandwich hand, the China ink pipe by cap, hollow, sandwich tube, piston, control China ink core, nib and the pen core of hollow; Wherein, slide successively and be provided with described sandwich hand, described spring and described by cap at described penholder inner chamber, describedly by the cap outer end, be placed in the described penholder one end outside; At the described penholder other end, be provided with described China ink pipe, described sandwich on hand active card be connected to described sandwich tube, described sandwich tube one end is placed in described penholder inner chamber, the described sandwich tube other end is placed in described black tube cavity; On the described sandwich tube of described black tube cavity, be provided with described piston, the port on described China ink pipe top is provided with the black core of described control, is provided with described nib at the black in-core of described control, is filled with ink at described piston to the described black tube cavity between the black core of described control; In described sandwich tube, be provided with described pen core, described pen core top is passed described black tube cavity and described nib successively, and described pen core top is placed in the described nib outside.

Advantage of the present utility model: can solve the nib wearing and tearing of needle tubing pen, pen core can outwards be got, and has improved the utilization rate of pen core, has prevented the evaporation of pen and ink, and in black pipe, can fill with ink can reuse.

The accompanying drawing explanation:

Fig. 1 is generalized section of the present utility model.

Penholder 1, spring 2, sandwich hand 3, press cap 4, China ink pipe 5, sandwich tube 6, piston 7, the black core 8 of control, nib 9, pen core 10.

The specific embodiment: as shown in Figure 1, the automatic needle tube pen, it comprises penholder 1, spring 2, sandwich hand 3, the China ink pipe 5 by cap 4, hollow, sandwich tube 6, piston 7, the black core 8 of control, nib 9, the pen core 10 of hollow; Wherein, at penholder 1 inner chamber, slide successively and be provided with sandwich hand 3, spring 2 and, by cap 4, be placed in the penholder 1 one ends outsides by cap 4 outer ends; At penholder 1 other end, be provided with China ink pipe 5, active card is connected to sandwich tube 6 on sandwich hand 3, and sandwich tube 6 one ends are placed in penholder 1 inner chamber, and sandwich tube 6 other ends are placed in China ink pipe 5 inner chambers; On the sandwich tube 6 of China ink pipe 5 inner chambers, be provided with piston 7, the port on China ink pipe 5 tops is provided with the black core 8 of control, is provided with nib 9 in the black core 8 of control, at piston 7 to China ink pipe 5 lumen loadings between the black core 8 of control, ink is arranged; In sandwich tube 6, be provided with pen core 10, pen core 10 tops are passed China ink pipe 5 inner chambers and nib 9 successively, and pen core 10 tops are placed in written 9 outsides.

Operation instruction: press penholder 1 end by cap 4, promoting spring 2 shrinks, sandwich hand 3 stretches out downwards, and sandwich tube 6 is ejected to penholder 1 top, and pushing piston 7 ejects downwards with pen core 10, control black core 8 and control the outflow of ink, after pen core 10 ejected, the cap for brush 4 recovered initial point, and spring 2 recovers, sandwich hand 3 clamps sandwich tube 6 to reclaiming contracting, and pen core 10 is fixing.So action repeats until the top length of pen core 10 is satisfied.
