Documents two, the patent No.: 201010204868.5, the applying date: 2010.06.21; Notification number: CN101862490A, the patentee: Wenling city Millennium light medical apparatus and instruments company limited, this case discloses " a kind of self-destruction insulin syringe capable of replacing needle "; Comprise syringe, push rod, plug, needle stand, the push rod front end is connected with frustum through the core of the card, and needle stand is removable the connection with the syringe front end; Be provided with the needle holder that syringe needle is installed in the needle stand, be provided with water shutoff O type elastic seal ring between needle holder and the needle stand, it is characterized in that: syringe is provided with the connection needle stand that matches with needle holder; Connect needle stand and be supported and fixed on the syringe front end by supporting seat, the downward elongation moulding of needle holder has retainer ring, connects the needle stand upper end and forms snap ring; Snap ring stretches into the retainer ring endoporus and is fixed togather with retainer ring, and the hole wall that connects the needle stand endoporus is provided with big groove, and the supporting seat upper end is stretched into and connected the needle stand endoporus; The supporting seat upper end forms first elastic pawl of gathering to the center, and the outside, supporting seat upper end is provided with a circle boss, and boss drops in the big groove; And can slide up and down along big groove, connect the needle stand lower end and form the first elasticity support claw, correspondingly the syringe inwall is provided with the embeddable little groove of the first elasticity support claw; The supporting seat lower outside is provided with a circle boss shoulder, and the boss shoulder offsets with the first elasticity support claw.
Be not difficult to find out that from above-mentioned prior art it is too complicated to have the overall structure that can change pin haulback type safe self-breaking syringe now, required assembling parts is more, and can't assemble at the full-automatic rear portion of reality, has had a strong impact on packaging efficiency and assembly precision.
Moreover also there is unreasonable part in the exchangeable needle monomer structure, and for example, sealing effectiveness is not satisfactory, need carry out the secondary demoulding, has increased production cost.
So still need the needle construction of changing of pumpback formula safety self-destructing syringe be further improved.
Summary of the invention
The purpose of this utility model is to provide a kind of needle stand structure that is used for changing the pin safe self-breaking syringe; It is reasonable in design to change the needle stand monomer structure; Can adopt two kinds of forms of evolute and inner-rotary type; The 6:100 international standards are adopted in itself and the interior needle stand screw-on place of syringe, have good sealing effectiveness, have overcome the shortcoming and defect that exists in the prior art.
To achieve these goals; The technical scheme of this utility model is: a kind of needle stand structure that is used for changing the pin safe self-breaking syringe; It comprises the needle stand body, and the needle stand body end is provided with needle tubing, it is characterized in that: said needle stand body outer wall place is provided with at least two rotation fins.
A kind of needle stand structure that is used for to change the pin safe self-breaking syringe; It comprises the needle stand body; The needle stand body end is provided with needle tubing, it is characterized in that: the column cavity of formation and needle tubing UNICOM in the said needle stand body, column cavity inner wall place is provided with at least two rotation fins.
The utility model discloses a kind of needle stand structure that is used for changing the pin safe self-breaking syringe, it adopts built-in rotation fin or two kinds of forms of external rotation fin, matches with the screw thread assembly structure of interior needle stand; Installation step is convenient, and locking effect is stable, and the international standard of 6:100 tapering is all adopted in both screw-on places; Have sealing effectiveness very, it is reasonable to change the needle stand overall construction design, but one-shot forming; Need not the secondary demoulding; Replacement step is simple in the operation, and stable working state has outstanding substantive distinguishing features and marked improvement compared to existing technologies.
