Description

A kind of ball-pen point connection structure

Technical field

The utility model relates to a kind of ball pens, more particularly, to a kind of ball-pen point connection structure.

Background technique

Ball pen (Ball Point Pen) or ballpoint pen are freely to be turned using dry consistence ink by nib Dynamic steel ball brings out a kind of writing implement in transcription to paper.Ball pen is simple, easy to carry with structure, writes lubrication, And the advantages that being suitable for for making carbon copies, thus, the people from all walks of life such as civilian personnel from the student of school to office building are happy to make With.

Ball pen is various in style, style is different, has pressing, bushing type etc. a variety of.One of the most common type ball pen at present Including pen core, pen body, nib and pen cap, wherein pen cap is placed on the pen tip protected in pen core outside nib, and pen core is located in pen body, pen Pen tip in core passes through nib and is exposed to outside nib, and pen core is pressed in pen body by the gland on pen body top so that circle Pearl pen pen core when writing will not be retracted in pen body, and now for the ease of replacing pen core, it is usually removable between nib and pen body Connection is unloaded, the most common connection type is using threaded connection, i.e. pen body inner wall is equipped with internal screw thread, and written upper end is equipped with screw thread Thread segment is inserted into pen body when connection and screwed by section.Nib with using being threadedly coupled, needed between pen body by written or pen The two could be fully connected fixation by body multi-turn rotation, more time-consuming and laborious, while in writing process, the two is easy to occur It relatively rotates, so that the pen tip in pen core can be retracted in pen body, stability in use is poor, will affect writing.

Utility model content

The utility model is to solve the nib of the prior art with pen body using being threadedly coupled, and assembly is time-consuming and laborious, together When in writing process, the two is easy to relatively rotate so that the pen tip in pen core can be retracted in pen body, stability in use Difference the problem of will affect writing, provides that a kind of structure is simple, and quickly, conveniently, nib is connected firmly with pen body for assembly, is not easy It disengages, the good ball-pen point connection structure of stability in use.

To achieve the goals above, the utility model uses following technical scheme:

A kind of ball-pen point connection structure of the utility model, including pen body and nib, the nib include in being The pinching of hollow tube-like structure holds section and card with section, it is described pinch to hold stop collar side is equipped on the outside of section upper opening, the stop collar side Outer diameter is greater than the outer diameter of pen body, and stop collar side is contacted with pen body lower end surface, and the card is set on stop collar side with section and card is matched Section lower end is fixedly connected with stop collar side, and card is adapted with section outer diameter with pen body internal diameter, is blocked and is matched that section lateral surface is circumferentially spaced to be set There are several raised lines, be interference fitted between the raised line and pen body inner wall, the card above raised line is equipped with limit with section lateral surface Bulge loop, the pen body inner wall are equipped with the cyclic annular limiting slot to match with position limiting convex ring, and card is equipped with guide section, the guiding with section upper end Section outer diameter is less than card and matches section outer diameter.The utility model abandoned nib with the traditional thread connecting mode of pen body, using nib with The connection type of pen body inserting improves the connection structure of ball-pen point；Play limit in stop collar side in nib Effect (depth of the limitation card with section insertion pen body), while the effect of positioning is also acted as, when end in contact under stop collar side and pen body When, position limiting convex ring is just caught in cyclic annular limiting slot；Guide section plays guiding role, since guide section outer diameter is less than card with outside section Diameter, so that guide section can be readily intercalated into pen body；Since card is adapted with section outer diameter with pen body internal diameter, when card is inserted into pen body with section When middle, card is just squeezed and is interference fitted between pen body inner wall with the raised line on section lateral surface, so that raised line and pen It is not likely to produce relative displacement between body inner wall, realizes the fixation of nib with pen body；Position limiting convex ring is adapted with cyclic annular limiting slot, energy Nib is further avoided to exit from pen body.

Preferably, the lateral angle of the guide section upper end is set as outer chamfer.The lateral angle of guide section upper end falls outside being set as Angle, outer chamfer can be rounded corner, play the role of guiding, convenient in guide section quick insertion pen body.

Preferably, the upper end end face of the raised line is set as inclined-plane, which forms guide surface, between guide surface and raised line Turning point arc transition.The upper end end face of raised line is set as inclined-plane, and the turning point arc transition between guide surface and raised line works as card When in section insertion pen body, the resistance between raised line and pen body is small, convenient for card in section quick insertion pen body.

Preferably, the card is set as outer chamfer with the lateral angle of section upper end.The lateral angle that card matches section upper end falls outside being set as Angle, outer chamfer can be rounded corner, play the role of guiding, convenient for card in section quick insertion pen body.

Preferably, described pinch holds section, blocks and integrally tie with section, stop collar side, raised line, position limiting convex ring and guide section for homogeneity Structure.Pinching and holding section, card with section, stop collar side, raised line, position limiting convex ring and guide section is homogeneity integral structure, and structural strength is good, processing Convenient formation, using integrally formed.

Therefore, the utility model has the following beneficial effects: structure is simple, assembly quickly, conveniently, passes through raised line and pen body The dual fixation that interference fit, position limiting convex ring and cyclic annular limiting slot card are matched between inner wall to realize between nib and pen body jointly It is fixedly connected, so that nib is connected firmly with pen body, is not easy to disengage, stability in use is good.
