The pen point is of thorough cavity structure, partial cavities of the fixing tube are cylinder-shaped with different diameters, the outer diameter of the portion of the fixing tube matched with ink storage tube is less than that of the remaining portions of the fixing tube, the pen tip is cone-shaped and partial cavities of the pen tip are of cone-shaped structure on both ends, and cylinder-shaped structure on middle portions.
Description
Technical field
The utility model belongs to the stationery field, refers to especially a kind of improvement structure of gel ink pen head.
Background technology
Be used for writing pen, mainly can be divided three classes since modern age: pencil, pen and gel ink pen, the range of application of pencil now mainly concentrates on the field of pupil's use and some specific needs; The scope of application of pen is more extensive, substantially can be applied to each field of writing, but pen also has the defective that is difficult to overcome to need exactly to replenish ink, and particularly now in the situation to the impact of writing popularized of computer, the shortcoming of pen is just more obvious in the fields such as office or enterprise.The advantages such as in order to overcome the defective of pen, gel ink pen has obtained having developed using also and popularized rapidly, and gel ink pen has to be write conveniently, and person's handwriting is lasting, and printing ink is concentrated.
But gel ink pen also has certain defective, the nib of Here it is gel ink pen is ink leak and printing ink that for a long time need not the written section defective of solidifying easily, this mainly is to realize by the space of the ball of nib and nib section by gravity because the existing gel ink pen nib of using is printing ink, printing ink in nib and ball section when the user does not use still exists, will occur like this printing ink overflow or for a long time need not after, be in the printing ink of nib and ball section because stopping up whole nib near the air drying, to whole pen scrapped.
Prior art has had the nib that proposes the centering pen to improve, and by add spring in nib, realizes nib with the tight seal between the ball of nib by the pressure of spring, but also has obvious defective part according to prior art exactly:
Because of the volume of nib place volume much smaller than stationary pipes, the inner chamber of stationary pipes is also greater than the inner chamber at nib place, particularly the nib end is used for by the hole size of spring limited, cause each cavity internal diameter of written section different, just must use the spring of various outer diameter, particularly the top presses ball partial spring diameter to be significantly less than the other parts spring diameter, causes like this pressure of spring to occur tilting, and on the contrary the sealing nib is not played due effect with ball.
The utility model content
The purpose of this utility model is that existing gel ink pen technology is proposed to improve, so that this gel ink pen can provide printing ink according to user's needs, prevents the printing ink spill and leakage or also can reduce difficulty of processing when solidifying.
The utility model is achieved through the following technical solutions:
The improvement structure of gel ink pen head, described nib is divided into stationary pipes and nib two parts, described nib is for there being the perforation cavity structure, described stationary pipes part cavity is different cylindrical of diameter, described stationary pipes is used for the storage ink tube external diameter of part external diameter less than part more than the stationary pipes that match, it is conical that described nib profile is, and described nib part cavity is two terminal circle taper intermediate cylindrical structure.
Described stationary pipes and nib are integrated setting, described nib end is provided with cavity, be provided with ball in the described cavity, described ball partly exposes outside the cavity, described cavity bottom is porose to communicate with stationary pipes and nib, described nib cavity with the cavity bottom hole be connected the part internal diameter identical with the aperture in cavity bottom hole, be provided with the oil storage tank structure around the hole of described cavity bottom, be provided with spring in described stationary pipes and the nib, described spring is pressed ball by the top, hole of cavity bottom, the spiral external diameter that described spring forms is identical, and described stationary pipes inner chamber body is comprised of two different inner diameters, and nearly nib direction internal diameter is little in these two internal diameters.
The minimum diameter that connects in the stationary pipes part taper shape in the described nib part cavity is identical with the intermediate cylindrical internal diameter, and the described minimum diameter that connects in the stationary pipes part taper shape is identical with connecing the conical maximum inner diameter of cavity part.
Described oil storage tank is 3-5, and described oil storage tank is communicated with cavity and nib inner chamber.
The rear end of described cavity is the conical internal cavity wall, and the front end of cavity is cylindrical.
The side of described cavity rear end conical internal cavity wall becomes 120-135 degree angle with the side of cavity front end taper internal chamber wall.
The groove of inwardly giving prominence to that is positioned at same cross section is arranged on the described stationary pipes, and described groove is 3-4.
The beneficial effects of the utility model are:
Pass through the technical solution of the utility model, design to written inner chamber body, so that spring can remain on the same axis, having guaranteed that printing ink can't overflow can guarantee that also air does not enter nib section and prevents ink setting, and directly strengthens the hole of cavity rear end and do not need to process separately oil storage tank or oil storage hole again.

The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, in the example of described embodiment from start to finish same or similar label represent same or similar parts or the parts with identical or similar functions.The embodiment that the following describes is exemplary, only is used for explaining this patent, and can not be interpreted as the restriction to this patent.
With reference to illustrated in figures 1 and 2, the improvement structure of gel ink pen head, described nib is divided into stationary pipes 11 and nib 12 two parts, described nib is for there being the cavity of perforation 17 structures, described stationary pipes part cavity is different cylindrical of diameter, described stationary pipes is used for matching the part external diameter less than the external diameter of part more than the stationary pipes with the storage ink tube, and it is conical that described nib 12 profiles are, and described nib part inner chamber 36 is two terminal circle taper intermediate cylindrical structure.
Described stationary pipes 11 and nib 12 are integrated setting, described nib 11 ends are provided with cavity 13, be provided with ball 14 in the described cavity 13, described ball 14 parts are exposed outside the cavity 13, described cavity bottom porose 15 communicates with stationary pipes 11 and nib 12, described nib inner chamber 36 with cavity bottom hole 15 be connected the part internal diameter identical with the aperture in cavity bottom hole, be provided with oil storage tank (22 around the hole 15 of described cavity bottom, 23,24,25) structure, be provided with spring 16 in described stationary pipes 11 and the nib 12, described spring 16 is pressed ball 14 by 15 tops, hole of cavity bottom, and the spiral external diameter that described spring forms is identical, described stationary pipes inner chamber body is comprised of two different inner diameters, and nearly nib direction internal diameter is little in these two internal diameters.
