Description
Technical field
The utility model relates to a kind of stationery, specifically a kind of ink leakage proof pen can avoiding ink leakage.
Background technology
Existing pen generally includes nib, proposition, penholder, barrel and the cap for brush, nib, proposition, barrel and the cap for brush are all arranged on penholder, ink in barrel flows on proposition by an ink barrel, then wetting nib, and such user just can use pen to carry out having write.Existing pen is owing to freely communicating between barrel and proposition, and the area of proposition is comparatively large, also comparatively large to the volatilization of ink, therefore easily occurs the situation of ink abnormal waste-ink leak.
Based on this, special proposition the utility model.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the utility model provides a kind of ink leakage proof pen, and the situation can preventing and treating the abnormal waste-ink leak of ink occurs.
The utility model adopts following technical scheme: a kind of ink leakage proof pen, comprise nib, proposition, penholder, barrel and the cap for brush, nib, proposition, barrel and the cap for brush are all arranged on penholder, there is through side opening vertical with ink channel the position that penholder holds a pen, in side opening, plunger assembly is installed, axially extending bore in described plunger assembly and ink channel stagger a segment distance, axially extending bore will be caused to be communicated with ink channel after the spring pressurized in plunger assembly.
Further, described plunger assembly comprises plunger bushing, plunger and spring, described plunger bushing has the first through hole and the second through hole that are communicated with ink channel, described plunger and described enclosing springs are in described plunger bushing, plunger has described axially extending bore, the first through hole on described axially extending bore and plunger bushing and the second through hole stagger a segment distance, compress described spring and axially extending bore can be allowed to be communicated with the second through hole with the first through hole on plunger bushing.
Further, described plunger assembly also comprises a threaded block, and described threaded block is socketed in the tail end of plunger bushing, and threaded block is threaded with penholder.
The beneficial effects of the utility model: 1, owing to have employed normally closed plunger assembly, ink channel only just conducting with when thumb or forefinger pressing, can guarantee that pen can not ink leak like this; 2, ink leakage proof pen structure of the present utility model is simple, easy for installation.

Detailed description of the invention
Be described further below in conjunction with a kind of ink leakage proof pen of accompanying drawing 1,2 pairs of the utility model.
As shown in Figure 1, 2, ink leakage proof pen comprises the common part of existing common pen, as nib 1, proposition (not shown), penholder 2, barrel (not shown) and the cap for brush 3, nib 1, proposition, barrel and the cap for brush 3 is all arranged on penholder 2, there is through side opening 21 vertical with ink channel 5 position that penholder 2 holds a pen, plunger assembly 4 is installed in side opening 21, axially extending bore in described plunger assembly 4 421 and ink channel 5 stagger a segment distance, axially extending bore 421 will be caused to be communicated with ink channel 5 after the spring pressurized in plunger assembly 4.
Plunger assembly 4 comprises plunger bushing 41, plunger 42 and spring 43, described plunger bushing 41 has the first through hole 411 and the second through hole 412 be communicated with ink channel 5, described plunger 42 and described spring 43 are encapsulated in described plunger bushing 41, plunger 42 has described axially extending bore 421, described axially extending bore 421 and the first through hole 411 on plunger bushing 41 and the second through hole 412 stagger a segment distance, compress described spring 43 and axially extending bore 421 can be allowed to be communicated with the second through hole 412 with the first through hole 411 on plunger bushing 41.
Plunger assembly 4 can adopt various ways to be arranged on penholder 2, and such as, side opening 21 on penholder 2 is screwed hole, and plunger bushing 41 outer surface is shaped with screw thread, is arranged on penholder 2 by plunger assembly 4 by threaded engagement.Preferably, penholder 2 has relatively two holes, one is through hole, another is screwed hole, and plunger assembly 4 also comprises a threaded block 44, and described threaded block 44 is socketed in the tail end of plunger bushing 41, the two adopts interference fit, and threaded block 44 is threaded with penholder 42.
This ink leakage proof pen of the present utility model, only have in use due to hold a pen produce grip make plunger 42 inwards movement make ink channel 5 conducting of penholder 2, ink can flow to nib 1 by barrel, the used time does not act on lower plunger 42 at spring 43 and the ink channel 5 of penholder 2 is blocked cut-off, the pen ink leak when not using can be prevented, easy to use and ink leakage proof is effective compared with existing pen.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the present utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
