Description

A kind of ink box cover

Technical field

The utility model relates to ink print consumptive material fields, more particularly to a kind of ink box cover.

Background technique

As illustrated in fig. 1 and 2, ink box cover 1 covers ink cartridge mouth 2 for sealing, including coaxially arranged lid 11 and column Plug 12.Lid 11 has internal screw thread 111, and for cooperating with the external screw thread 21 of ink cartridge mouth 2, plunger 12 is out of, lid 11 top Side extends downwardly.The plunger 12 of existing ink box cover 1 has circular hole 121, and ink enters in circular hole 121 in order to prevent, usually It needs to place a leak-proof washer 3 with gasket film 31 between plunger 12 and the ink export 22 of ink cartridge mouth 2.This not only increases Add material cost, and assembled trouble, increases cost of labor.In addition, when in use, it is also necessary to gasket film 31 is broken, It is very inconvenient.

Summary of the invention

The utility model is intended to provide a kind of ink box cover, to solve the above problems.For this purpose, the tool that the utility model uses Body technique scheme is as follows:

A kind of ink box cover, including coaxially arranged lid and plunger, the lid has internal screw thread, is used for and ink cartridge The external screw thread of mouth cooperates, and the plunger is extended downwardly from the inside top of the lid, wherein the terminal part of the plunger is flat Face, for sealing the ink export in the ink cartridge mouth.

Further, the plunger has a cavity, and the cavities open is in the lid upper surface.

Further, the cavity is funnel-shaped.

Further, the ink box cover is made of plastics.

The utility model by adopting the above technical scheme, has the beneficial effect that the utility model by by the end of plunger End is changed to plane, eliminates leak-proof washer, saves material cost, the convenience for substantially increasing assembling and using.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

As shown in Figures 3 and 4, a kind of ink box cover 1 includes coaxially arranged lid 11 and plunger 12.The structure of lid 11 with The prior art is the same.Lid 11 has internal screw thread 111, for cooperating with the external screw thread 21 of ink cartridge mouth 2 (referring to Fig. 1).Plunger 12 extend downwardly from the inside top of lid 11, and terminal part 121 is plane, go out for sealing the ink in the ink cartridge mouth Mouth 22.Specifically, 1 millimeter (thickness of leak-proof washer 3) longer than existing plunger 12 (referring to Fig. 1 and 2) of plunger 12.Therefore, pacify When dress, it is only necessary to which sealing ink export 22 can be realized by tightening ink box cover 1；In use, an ink box cover 1 is only needed to twist off i.e. It can.It assembles and very easy to use.

In order to save material cost, plunger 12 has a cavity 122, and the cavity 122 is opened on 11 upper surface of lid.In In illustrated embodiment, the cavity 122 is funnel-shaped, i.e., its opening is taper.Certainly, cavity 122 is not limited to shown shape.

Ink box cover 1 can be made up of plastics or rubber etc. of injection molding.This is convenient for batch micro operations, saves system Cause this.

Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details On the utility model can be made a variety of changes, be the protection scope of the utility model.
