Description

Pen

Technical field

The present invention relates to cultural goods field, especially a kind of pen cap is not easy the pen lost.

Background technology

The pen that current people use, generally comprises penholder and the pen cap, and penholder and the pen cap are independent settings.The pen of this structure in use, the pen cap is generally inoperative, when taking off the pen cap and using this, because the pen cap and penholder are separately independently, the pen cap is set in this other end, place it on one side individually, the pen cap is easily lost, thus the storage that pen is brought because not having the pen cap, the inconvenience of carrying.

For preventing the loss of the pen cap, application number disclosed in 4 days November in 2009 be 200820223613.1 innovation and creation disclose a kind of pen, comprise the pen cap and a body, body is provided with a bar, the pen cap is flexibly connected by strap means with bar, the pen cap is arranged a plug, and a body tail end has an opening, during use in plug insertion opening, thus the pen cap is not easily dropped.A program belt is connected in the pen cap on penholder, although the pen cap not easily drops, when using, because the pen cap is inserted in it pen, changes the center of gravity of pen entirety, uses feel bad.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of pen cap to be not easy the pen lost.

For achieving the above object, technical scheme of the present invention is: pen, comprise the pen cap, body, pen core and a body base, support and pen core base is provided with in described body, described support is provided with the hole passed through for pen core, described pen core base is provided with the depression inserted for pen core, spring is provided with between described support and pen core base, described pen core is through spring, described body base is provided with groove, convex shape card is provided with in the described pen cap, when the pen cap is enclosed within body, convex shape card ejects body by extruding pen core base the nib of pen core through groove, the described pen cap passes through turning handle convex shape card on pen core base.

The outside of the described pen cap is provided with pen clip, described pen clip and convex shape card in the same plane.

The described pen cap is made up of transparent material.

The invention has the beneficial effects as follows: when (1) uses, the convex shape card of the pen cap is ejected body by extruding pen core base the nib of pen core through groove, that is this is only had and could be used by the cooperation of the pen cap, the situation throwing out the pen cap without care can not be produced, avoid the loss of the pen cap; (2) the little ear of the band that the pen core on market has, what have does not have, has plenty of fountain pen refill, has plenty of ball pen, cooperatively interact between support of the present invention, pen core base, spring, these pen cores can be filled use on the invention, breach the conventional thought that fountain pen refill can only be used in a water-color paintbrush body, ball pen can only be used in ball pen body; (3) the convex shape card of the pen cap is owing to being arranged on pen cap inside, convex shape card to be inserted in a groove of body base and have certain difficulty, pen cap transparent material is made and is conducive to seeing convex shape card clearly, in convenient groove convex shape card being inserted a body base, optionally, also can at the arranged outside pen clip of the pen cap, pen clip and convex shape card in the same plane, cue mark is made, also in convenient groove convex shape card being inserted a body base with pen clip; (4) the present invention also has the advantage that structure is simple, easy to operate, be easy to carry about with one.

In figure: the pen cap 1, convex shape card 11, pen clip 12, a body 2, pen core 3, a body base 4, groove 41, support 5, hole 51, pen core base 6, depression 61, spring 7.

Detailed description of the invention

Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.

As shown in Figure 1 to 4, pen, comprise the pen cap 1, body 2, pen core 3 and a body base 4, support 5 and pen core base 6 is provided with in described body 2, described support 5 is circular, support 5 and be provided with the hole 51 passed through for pen core 3, described pen core base 6 is provided with the depression 61 inserted for pen core 3, depression 61 is cylindrical, columniform diameter is a bit larger tham the diameter of pen core 3, spring 7 is provided with between described support 5 and pen core base 6, described pen core 3 is through spring 7, described body base 4 is provided with groove 41, convex shape card 11 is provided with in the described pen cap 1, when the pen cap 1 is enclosed within body 2, convex shape card 11 ejects body 2 by extruding pen core base 6 the nib of pen core 3 through groove 41, the described pen cap 1 is stuck on pen core base 6 by turning handle convex shape card 11, after pen is finished using, rotate the pen cap 1 again, convex shape card 11 is alignd with groove 41 backed off after random groove 41, now the nib of pen core 3 is just retracted in a body 2.

Optionally, at the arranged outside pen clip 12 of the pen cap 1, pen clip 12 is in the same plane with convex shape card 11, makes cue mark with pen clip 12, also facilitates and convex shape card 11 is inserted in a groove of body base 4 41.

The described pen cap 1 is made up of transparent material, and naked eyes can see the structure of convex shape card 11 through the pen cap 1.

The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
