Description

A kind of pen cap of signature pen

Technical field

The present invention relates to the office appliance technical field, in particular, relate to a kind of pen cap of signature pen.

Background technology

At present, exist the signature pen of various styles, various brands on the market.The signature pen of different styles or different brands, the model of pen core (for example length or thickness) also is not quite similar.In use, pen core has been used up usually, and the pen cap is also intact, can change pen core and reuse.

But, signature pen of the prior art, because the pen cap is relatively stricter for the length requirement of pen core, the pen core kind that causes the pen cap to mate is limited, can't make full use of the pen cap.

Summary of the invention

In view of this, the invention provides a kind of pen cap of signature pen, can mate the pen core of all lengths, the pen cap of signature pen is fully utilized.

For achieving the above object, the invention provides following technical scheme:

A kind of pen cap of signature pen comprises: the outer pen cap and the interior pen cap; The external diameter of the pen cap is less than the internal diameter of the described outer pen cap in described;

The inwall of the described outer pen cap is provided with projection; On the outer wall of the pen cap, be provided with the barb groove that is complementary with described barb in described; Along the axial direction that is parallel to the described interior pen cap, also be provided with the groove that is complementary with described projection on the outer wall of the described interior pen cap.

Preferably, the inner tip of the described outer pen cap is the taper tapered configuration.

Preferably, also comprise:

Spring; The diameter of described spring, greater than the minimum diameter of the pen cap in described, and less than the projection of pen core lower end usually.

Via above-mentioned technical scheme as can be known, compared with prior art, the pen cap of signature pen of the present invention, by on the pen cap projection being set outside, and the barb groove that is complementary with described projection is set on the interior pen cap, the pen core that can mate all lengths can make the pen cap of signature pen be fully utilized.

The specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

Referring to Fig. 1, be the pen cap schematic diagram of the described signature pen of the embodiment of the invention.As shown in Figure 1, the described pen cap comprises: the outer pen cap 101 and the interior pen cap 102; The external diameter of the pen cap 102 is less than the internal diameter of the described outer pen cap 101 in described; The inwall of the described outer pen cap 101 is provided with projection 1011; On the outer wall of the pen cap 102, be provided with the barb groove 1021 that is complementary with described barb in described.Pen core 103 is normally used common pen core.

Among Fig. 1, pen core 103 is installed in the pen cap.On the barb groove 1021 in projection 1011 on the outer pen cap 101 is stuck on the pen cap 102.Projection 1011 on the outer pen cap 101 is stuck in the particular location on the barb groove 1021, can regulate according to the physical length of pen core 103.Therefore, the pen cap of the present invention can mate the pen core of all lengths.

Referring to Fig. 2, be the described interior pen cap generalized section of the embodiment of the invention.As shown in Figure 2, the described interior pen cap is provided with barb groove 1021.

Referring to Fig. 3, be the described interior pen cap schematic top plan view of the embodiment of the invention.As shown in Figure 3, along the axial direction that is parallel to the described interior pen cap 102, also be provided with and described protruding 101 grooves that are complementary 1022 on the outer wall of the described interior pen cap 102.

Described groove 1022 is used for the interior pen cap 102 is inserted in the outer pen cap 101.Concrete, the groove 1022 in can earlier the projection on the outer pen cap inwall 1011 being aimed on the pen cap outer wall is sent into the interior pen cap in the outer pen cap.At this moment, projection 1011 is arranged in groove 1022.Then, when the sending into length and reach appropriateness of the interior pen cap, rotate the outer pen cap 101, just projection 1011 can be rotated in the barb groove 1021.By above-mentioned steps, can realize nested and fixing to the inside and outside pen cap.

As seen, the pen cap of the present invention by on the pen cap projection being set outside, and is provided with the barb groove that is complementary with described projection on the interior pen cap, can mate the pen core of all lengths, and the pen cap of signature pen is fully utilized.

In the practical application, for the pen core to different thicknesses also can carry out good fixing, the inner tip of the described outer pen cap of the embodiment of the invention is the taper tapered configuration.

Referring to Fig. 4, be outer pen cap schematic diagram of the present invention.As shown in Figure 4, the inner tip of the described outer pen cap is a taper tapered configuration 1012.The taper tapered configuration can be fit to the different pen core of thickness.

Referring to Fig. 5, for the outer pen cap top schematic diagram of thick pen core is installed.As shown in Figure 5, pen core 103 is thicker, and then diameter is bigger, be stuck in taper tapered configuration 1012 relatively by under part.

Referring to Fig. 6, for the outer pen cap top schematic diagram of thin pen core is installed.As shown in Figure 6, pen core 103 is thinner, and then diameter is less, will be stuck in taper tapered configuration 1012 relatively by last part.

In the practical application, for more stable being fixed in the outer pen cap of the interior pen cap, the pen cap of the present invention also comprises:

Spring; The diameter of described spring, greater than the minimum diameter of the pen cap in described, and less than the projection of pen core lower end usually.

Among Fig. 1, spring 1013 is between the nib exit of the projection of pen core 103 lower ends and the interior pen cap.The existence of spring 1013, can play following effect: the projection outside the length of pen core makes on the pen cap, by chance when the groove of the barb groove 1021 on the interior pen cap and the interstitial site between the groove, described spring 1013 can outwards push up the interior pen cap, so that described protruding 1011 can withstand on the groove of barb groove 1021.In addition, when not using signature pen, interior pen cap rotation can also be made groove 1022 alignment bumps 1011.Under the elastic force of spring 1013, the interior pen cap is with protruding, and when the nib of pen core 103 partly was positioned at the inside of the pen cap 102, the pen cap in the rotation made projection 1011 be stuck in the relevant position of barb groove 1021.Like this, can save the cap for brush parts of common signature pen, play the effect of protection nib simultaneously.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
