Description

A kind of pen

Technical field

This utility model is related to writing pen technical field, specially a kind of pen.

Background technology

Conventional ink pen is mainly by nib, blotting hydrophone, ink storage pipe and penholder composition.In use, inhale repeatedly Ink is received, can be just continuing with.Conventional ink pen in blotting process needs for nib and penholder to inject ink bottle, and extruding is deposited Chu Guan, blotter sucking ink function.But when writing, due to the defect of internal structure design, ink water outlet and sealing effect Really bad, or it is suddenly too many to go out ink, or not going out suddenly ink, it is not uniform enough ink when causing to write, and affects ink The application of water-color paintbrush.

Utility model content

The purpose of this utility model is to provide a kind of pen, to solve the problems, such as to propose in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme：

A kind of pen, including pen core, a predecessor and clear pen urosome, the pen core activity are plugged in a predecessor, pen The outside of a predecessor is stretched out in one end of core, and the other end of the pen core connects one end of sealing ring, and sealing ring activity is placed in the In one snap ring inner chamber, on the pen core, be socketed with sponge ring, sponge ring is located in the inner chamber of a predecessor, the sealing ring it is another End connection expansion link one end, and the other end of expansion link be located at the second snap ring inner chamber in, the lateral wall of the expansion link and The internal chamber wall of the second snap ring is connected by spring, and first snap ring is connected in the inner chamber of the second snap ring, and the second snap ring is inserted It is connected in the inner chamber of the 3rd snap ring, the 3rd snap ring is provided with mounting groove, and mounting groove and sealing away from one end of the second snap ring Pearl interference fit, the threaded one end connection of described predecessor one end and clear pen urosome away from pen core, sets in clear pen urosome There is ink holding tank.

Preferably, described predecessor is provided with female thread, the lateral surface of the clear pen urosome away from the one side of pen core External screw thread is provided with, and female thread and external screw thread matching are arranged.

Preferably, the two ends pore size of the inner chamber of first snap ring is different, and the first snap ring is from away from pen core Hold and taper near the aperture of one end of pen core.

Preferably, the intersection of the expansion link and the second snap ring is provided with step trough, and spring is placed in step trough.

Compared with prior art, the beneficial effects of the utility model are：This ink pen structure is simple, the first snap ring, second The mutual clamping of three of snap ring and the 3rd snap ring, constitutes stable inner-cavity structure, sealing is provided with the inner chamber of the first snap ring Circle so that the good seal performance of whole ink, while being provided with mounting groove in one end of the 3rd snap ring, mounting groove is and sealing pearl mistake Be full of cooperation so that whole pen in use, by the blocking and separation of sealing pearl and mounting groove so that internal structure Freedom of motion, water steadying out of ink, clear pen urosome is due to being made of transparent plastics, it can be seen that last melted ink is finished, Improve the superior function of pen.

Specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Fig. 1-6 are referred to, this utility model provides a kind of technical scheme：

A kind of pen, including pen core 1, a predecessor 2 and clear pen urosome 12,1 activity of pen core are plugged in a predecessor 2, The outside of a predecessor 2 is stretched out in one end of pen core 1, and the other end of pen core 1 connects one end of sealing ring 4, and 4 activity of sealing ring is placed in In first snap ring, 5 inner chamber, on pen core 1, be socketed with sponge ring 3, sponge ring 3 is located in the inner chamber of a predecessor 2, sealing ring 4 it is another End connection expansion link 6 one end, and the other end of expansion link 6 be located at the second snap ring 7 inner chamber in, the lateral wall of expansion link 6 and The internal chamber wall of the second snap ring 7 is connected by spring 9, and the first snap ring 5 is connected in the inner chamber of the second snap ring 7, and the second snap ring 7 is inserted It is connected in the inner chamber of the 3rd snap ring 8, the 3rd snap ring 8 is provided with mounting groove 10 away from one end of the second snap ring 7, and mounting groove 10 and only 11 interference fit of the globule, the threaded one end connection an of predecessor 2 one end and clear pen urosome 12 away from pen core 1, and clear pen tail Ink holding tank is provided with body 12, a predecessor 2 is provided with female thread, the outside of clear pen urosome 12 away from the one side of pen core 1 Face is provided with external screw thread, and female thread and external screw thread matching are arranged, and the two ends pore size of the inner chamber of the first snap ring 5 is different, and First snap ring 5 is tapered into from the one end away from pen core 1 to the aperture of one end near pen core 1, expansion link 6 and the second snap ring 7 Intersection be provided with step trough, and spring 9 is placed in step trough.

Operation principle：When writing, due under the naturalness that the elastic force of spring 9 is acted on so that flexible Bar 6 withstands sealing ring 4, so that sealing ring 4 blocks the inner chamber of the first snap ring 5, ink will not flow out, when needing to write Wait, can firmly extrude pen core 1, now, pen core 1 can promote sealing ring 4 and expansion link 6 together towards clear pen urosome 12 Mobile, spring 9 is squeezed, while sealing pearl 11 is backed down, is provided with ink holding tank in dropping into clear pen urosome 12, ink Then water smoothly write out ink through the inner chamber of the 3rd snap ring 8, the inner chamber of the second snap ring 7, the inner chamber of the first snap ring 5 and pen core 1 The uniform font of water, clear pen urosome 12 is due to being made of transparent plastics, it can be seen that last melted ink is finished.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, Be appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repair Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
