Description
Technical Field
The utility model relates to a gel ink pen head.
Background
The gel pen point is used for a gel pen, is connected with the ink tube of the pen core and is matched with gel ink for use, so that the gel pen point is smooth in writing and comfortable in hand feeling, has the advantages of a fountain pen and an oil-based ball pen, and is comfortable in writing hand feeling. Common gel-ink pens include full-needle gel-ink pens and bullet-type gel-ink pens. The full needle tube type gel ink pen point is processed by the needle tube, is suitable for being manufactured into a thinner pen point, is light and soft, has clearer written characters, and is easy to break. The bullet type neutral pen point is formed by cutting an original rod through a metal cutting process, is stable in ink output, is suitable for being manufactured into a thick pen point, and is not easy to break. At present, the design of the gel ink pen head can only meet the requirement of an ink tube with a conventional capacity (generally, the writing length is 11-14 meters), and if the ink tube is enlarged and thickened to increase the volume capacity of the gel ink in the ink tube, the service life of the existing gel ink pen head cannot be matched with the ink tube with a large capacity.
SUMMERY OF THE UTILITY MODEL
In view of the technical problem who exists among the background art, the utility model provides a technical problem aim at providing a novel longer neutral nib of life to satisfy and increase the use of capacity ink pipe.
In order to solve the technical problem, the utility model discloses a following technical scheme: novel longer neutral pen head of life, including pen point portion and main part, pen point portion links to each other as an organic whole structure with the main part, and the outer lane of pen point portion is the nib conical surface, and the tip of pen point portion is the ball seat, and the pearl of ball seat disposes the ball, its characterized in that in the pearl hole: the outer lane of main part is the face of cylinder and the end is the direction conical surface, the middle of nib portion and main part is the printing ink passageway that link up each other, the entry end of printing ink passageway sets up to the step hole, be the intercommunication aperture between printing ink passageway and the ball seat, be equipped with the axial on the inner wall of intercommunication aperture and cross the oil groove, printing ink passageway internal match has the spring, the needle portion of the front end of spring passes the intercommunication aperture and gets into to the ball downthehole of ball seat, the hole department in step hole has the arch in the middle of the orientation, the arch is located the rear end of spring, protruding and the spacing cooperation of spring.
The ink channel is composed of a plurality of cylindrical cavities with gradually reduced diameters from the main body part to the pen point part.
The projections are formed by stamping.
The beneficial effects of the utility model are that, this novel longer gel ink pen head of life need not additionally to set up the connecting portion that the external diameter diminishes and is used for connecting the printing ink pipe, and the structure is simpler, places the spring in its printing ink passageway after, and the punching press forms the arch on the step hole and is used for spacing fixed spring, and is rational in infrastructure, satisfies this gel ink pen head and increases life's demand relatively thick. Therefore, compared with the prior art, the utility model has substantive characteristics and progress.
Drawings
The following describes details and operational principles of embodiments and examples of the present invention with reference to the drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of a protrusion formed by punching an inner hole of the stepped hole and a spring placed in the inner hole of fig. 1.
Detailed Description
Referring to the attached drawings, the novel gel pen tip with longer service life in the embodiment comprises a pen tip part 1 and a main body part 2, wherein the pen tip part 1 and the main body part 2 are connected into a whole, the outer ring of the pen tip part is a pen tip conical surface 3, the end part of the pen tip part 1 is a ball seat, a ball 4 is arranged in a ball hole of the ball seat, the ball can roll in the ball hole of the ball seat, and the ball is used for writing.
The outer ring of the main body part is a cylindrical surface 5, the tail end of the main body part is a guide conical surface 6, and the main body part of the pen point can be conveniently and directly inserted into the ink tube through the guide conical surface 6. The centre of nib portion and main part is ink passageway 7 that link up each other, ink passageway 7's entry end sets up to step hole 71, be intercommunication aperture 8 between ink passageway and the ball seat, the intercommunication aperture can be processed through the mode of drilling, be equipped with the axial on the inner wall of intercommunication aperture and cross the oil groove (not shown in the figure), so that ink passes through, ink passageway 7 is internal to be furnished with spring 9, the needle portion 91 of the front end of spring passes intercommunication aperture 8 and enters into to the ball hole 41 of ball seat in, the hole department of step hole has the arch 72 towards the centre, arch 72 is located the rear end of spring 9, protruding and the spacing cooperation of spring. The rear end 92 of the spring is wound with a large diameter portion to stabilize in the ink channel. The neutral pen head of this structure can make the thick nib of size relatively, and life is longer, can match the printing ink pipe of large capacity and use, and it is thick to lead to the wall between its printing ink passageway and the outside under the thick condition of size, is difficult to carry out the processing of needle point with the mode of dashing the needle, is difficult to process on the lateral wall from the outside to the inboard bellied needle point of extrusion and is used for spacing spring, and the utility model discloses in with the arch on the step hole be used for spacing fixed spring, rational in infrastructure, satisfy this neutral pen head and strengthen life's demand relatively thick. The bulges are formed by punching, namely, the inner hole of the step hole is punched to form the bulges formed towards the middle, the processing is convenient, the inner hole of the step hole is pressed to the middle bulges by punching, and a triangular punch can be adopted to punch the edges of the inner hole of the step hole to form 3 equally-divided bulges.
In addition, the ink channel is composed of a plurality of cylindrical cavities with gradually reduced diameters from the main body part to the pen point part. The number of cylinder type cavity can be set for according to actual conditions, for example can set up more than 3, conveniently processes the printing ink passageway through the mode of drilling, makes the drill bit waste discharge more smoothly at the during operation, avoids the drill bit to break.
