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 present invention provides a kind of pen cap of signature pen, can mate the pen core of all lengths, and the pen cap of signature pen is fully utilized.

For realizing above-mentioned purpose, the present 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 said outer pen cap in said;

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

Preferably, the inner tip of the said outer pen cap is the conical taper structure.

Preferably, also comprise:

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

Can know via above-mentioned technical scheme; Compared with prior art; The pen cap of signature pen according to the invention through on the pen cap convexity being set outside, and is provided with the barb groove that is complementary with said convexity 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

To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, 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 are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

Referring to Fig. 1, be the pen cap sketch map of the said signature pen of the embodiment of the invention.As shown in Figure 1, the said 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 said outer pen cap 101 in said; The inwall of the said outer pen cap 101 is provided with protruding 1011; On the outer wall of the pen cap 102, be provided with the barb groove 1021 that is complementary with said barb in said.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 convexity 1011 on the outer pen cap 101 is stuck on the pen cap 102.Convexity 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 according to the invention can mate the pen core of all lengths.

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

Referring to Fig. 3, be the said 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 said interior pen cap 102, also be provided with the groove 1022 that is complementary with said protruding 101 on the outer wall of the said interior pen cap 102.

Said 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 convexity 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, protruding 1011 are 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 can rotate in the barb groove 1021 protruding 1011.Through above-mentioned steps, can realize nested and fixing to the inside and outside pen cap.

It is thus clear that the pen cap according to the invention through on the pen cap convexity being set outside, and is provided with the barb groove that is complementary with said convexity 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 said outer pen cap of the embodiment of the invention is the conical taper structure.

Referring to Fig. 4, be outer pen cap sketch map according to the invention.As shown in Figure 4, the inner tip of the said outer pen cap is a conical taper structure 1012.The conical taper structure can be fit to the different pen core of thickness.

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

Referring to Fig. 6, for the outer pen cap top sketch map of thin pen core is installed.As shown in Figure 6, pen core 103 is thinner, and then diameter is less, leans on last part relatively with being stuck in conical taper structure 1012.

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:

Among Fig. 1, spring 1013 is between the nib exit of the convexity of pen core 103 lower ends and the interior pen cap.The existence of spring 1013; Can play following effect: the convexity 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; Said spring 1013 can outwards push up the interior pen cap, so that said protruding 1011 can withstand on the groove of barb groove 1021.In addition, when not using signature pen, can also interior pen cap rotation 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 convexity 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 General Principle can realize under the situation that does not break away from the spirit or scope of the present invention in other embodiments among this paper.Therefore, the present invention will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
