Description

Can use the pen of ink barrel instead

Technical field

The utility model relates to a kind of writing implement, the removable pen of especially a kind of ink barrel.

Background technology

Present known pen has generally comprised a body, nib and ink barrel, ink barrel and a body be connected as a single entity indissociable; After ink in the ink barrel uses up, must put in nib and draw ink in the ink bottle, be filled ink after; The part of a nib and a body all speckles with ink; Need wiping, the inconvenience hand of also making dirty easily, and also ink bottle is carried also inconvenient.

The utility model content

The utility model provides a kind of pen of using ink barrel instead, and it can solve existing pen and when ink, must put in ink bottle to nib and draw ink, add the black problem of making hand dirty of being inconvenient to be prone to.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: include a body, nib and ink barrel; Said body is communicated in the passage of said nib the thimble pipe is housed, and said passage is an I shape, and the head of said thimble pipe places on the step surface on said passage top; The bottom of said thimble pipe places under the step surface of said passage bottom, and said body is connected with said ink barrel through screw thread.

In the technique scheme, scheme is more specifically: the head of said thimble pipe can be through the thimble pipe cap that has been threaded, and the bottom of this thimble pipe cap can be provided with the sealing gasket that is used to seal the ink channel mouth; The bottom of said thimble pipe can be provided with boss, can be provided with the compression spring between the step surface of said boss and said passage bottom, and the lower surface of said boss can be provided with sealing gasket; The said thimble pipe afterbody that stretches in the said ink barrel can be cylindrical body; Be provided with sealing ring between this thimble pipe afterbody and the said ink barrel, be provided with sealing ring between said thimble pipe top and said body, the said thimble pipe afterbody that stretches in the said ink barrel also can be reverse frustoconic; The bottom of said boss and the said contacted face of pipe of going up are provided with sealing gasket; Be provided with sealing ring between said thimble pipe top and said body, said ink barrel is made up of with managing down last pipe, and the said pipe of going up is hard tube; Said down pipe is flexible pipe, the bottom of said pipe box down pipe on said.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, because a body is connected with ink barrel through screw thread, when the needs ink, the rotation ink barrel can make an ink barrel and a status leave; Be screwed to pen to another ink barrel of filling ink and get final product on one's body, very convenient quick, and place the thimble tube head in the passage to stretch out on the step surface on passage top; When outwarding winding ink barrel; The thimble tube head moves down, and blocks ink channel, and the ink that remains in the nib can not spill.

2, the head of thimble pipe has the bottom to be provided with the thimble pipe cap of sealing gasket; When moving down, can better block ink channel like this; Good airproof performance, and be provided with the compression spring between the step surface of boss on the thimble pipe and passage bottom, make the thimble pipe move down fast more rapidly.

The specific embodiment

Below in conjunction with the accompanying drawing instance the utility model is done further to detail:

Embodiment 1 as shown in Figure 1 includes a body 9, nib 15 and by last pipe 3 and the following ink barrel formed of pipe 2, on to manage 3 be hard tube; Under manage 2 for flexible pipe, following pipe 2 is enclosed within manages 3 bottom, a body 9 is communicated in written 15 the passage 16 thimble pipe 7 is housed; Passage 16 is an I shape, and the head of thimble pipe 7 places on the step surface on passage 16 tops, and the bottom of thimble pipe 7 places under the step surface of passage 16 bottoms; Body 9 is managed 3 head through screw thread 5 and going up of ink barrel and is connected; The head of thimble pipe 7 is connected with thimble pipe cap 11 through screw thread 10, and the bottom of this thimble pipe cap is provided with the sealing gasket 6 that is used to seal ink channel mouth 17, has so just formed the seal switch; The bottom of thimble pipe 7 is provided with boss 7-1; Be provided with compression spring 8 between the step surface of boss 7-1 and passage 16 bottoms, the lower surface of boss 7-1 is provided with sealing gasket 6, and stretching into the thimble pipe afterbody 7-2 that manage in 3 on the ink barrel is cylindrical body; Going up between the pipe 3 of this thimble pipe afterbody 7-2 and ink barrel is provided with sealing ring 4, is provided with sealing ring 4 between thimble pipe 7 tops and the body 9.

After ink 1 used up, the derotation ink barrel was after the back-out; Thimble pipe 7 moves down under the active force of spring 8, and the step surface on sealing gasket pinch off channel 16 tops under the thimble pipe cap is sealed ink channel 17; Thereby remain in the ink in the nib in the sealing, make it to change an ink barrel that installs ink in advance then not toward dirty; It is screwed in the screw thread of a body, be screwed into the position after, the thimble pipe upwards moves; The lower surface of boss 7-1 is provided with sealing gasket 6 and two sealing rings and seals up ink and do not outbound flow, and squeezes pipe 2 down then, can normally use pen after discharging the air in ink barrel.
