Abstract
The invention relates to an injection pen which comprises a threaded button, a lead screw and a buckle. The threaded button is in a hollow shape with one end being open, and the inner wall of the threaded button is provided with threads. The surface of the lead screw is provided with threads, one end of the lead screw is inserted into the threaded button in a screw mode, the other end of the lead screw is exposed, and the lead screw is used for pushing a medicine bottle to conduct injection. The buckle is arranged at the opening end of the threaded button and is embedded on the lead screw in a sleeving mode, and the main structure is two symmetrical inverted hooks relative to the lead screw. The injection pen is simple in structure and convenient to use and carry, and the injection amount can be adjusted randomly.
Description
Technical field
The present invention relates to medical instruments field, specifically disclose a kind of injection pen.
Background technology
The injection pen existed in the market is of a great variety, and structure is changeable, and main exist some deficiency following:
1, existing syringe mostly is built-in medicine bottle, single use, can not realize recycled for multiple times, is unfavorable for reclaiming;
2, the production cost of product is higher, brings larger financial burden to consumer;
3, product component is various, and assembly technology is too complicated;
4, existing product size is comparatively large, not portable.
Summary of the invention
The object of the invention is to: provide that a kind of structure is simple for overcoming the above problems, volume be littlely easy to carry, easy to use, can the injection pen of recycled for multiple times.
The technical solution adopted in the present invention is such:
A kind of injection pen, comprises screw thread button, screw mandrel, buckle, and described screw thread button is the hollow form design of one end open, and within it wall is provided with screw thread; Described screw mandrel surface has screw thread, and its one end spiral inserts described screw thread button interior, and the other end exposes, and injects for advancing medicine bottle; Described buckle is arranged at described screw thread button openings end, is nested on described screw mandrel, and its agent structure is two barbs of relatively described screw mandrel symmetry.
Further, described screw thread button inner thread length is 1 ~ 3cm.
Further, described screw mandrel is symmetrically distributed with inclined-plane guide frame along its length, and on described buckle, barb and guide frame place, described inclined-plane abut against.
Further, described screw thread button all can rotate freely relatively with described screw mandrel.
Further, the pitch of described screw mandrel is 0.5 ~ 1.5mm.
In sum, owing to adopting technique scheme, the invention has the beneficial effects as follows:
1, each component structural of the present invention is simple, is convenient to manufacture;
2, user can regulate any injection volume according to the demand of oneself;
3, the design of buckle and screw mandrel in the present invention, can make this product repeatedly use, and dismounting is simple, easy to use;
4, compact structure of the present invention, is easy to carry.

Fig. 1 is structural representation of the present invention;
Fig. 2 is that Fig. 1 is along A-A direction sectional view;
Fig. 3 is screw thread press-button structure schematic diagram of the present invention;
Fig. 4 is screw structure schematic diagram of the present invention;
Fig. 5 is buckle structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Fig. 1 ~ 5, a kind of injection pen, comprises screw thread button 1, screw mandrel 2, buckle 3, and described screw thread button 1 is the hollow form design of one end open, and within it wall is provided with screw thread, and reach is 2cm; Described screw mandrel 2 surface has screw thread, and it is inner that its one end spiral inserts described screw thread button 1, and the other end exposes, and injects for advancing medicine bottle 4; Described buckle 3 is arranged at described screw thread button 1 opening, is nested on described screw mandrel 2, and its agent structure is two barbs of relatively described screw mandrel 2 symmetry.
Described screw mandrel 2 is symmetrically distributed with inclined-plane guide frame along its length, and on described buckle 3, barb and guide frame place, inclined-plane abut against; Described screw thread button 1 all can rotate freely relatively with described screw mandrel 2; The pitch of described screw mandrel 2 is 1mm.
Operation principle:
Before not loading medicine bottle 4, screw mandrel 2 and screw knob 1 all can rotate freely, and after loading medicine bottle 4, medicine bottle 4 inwall can force buckle 3 to be blocked by screw mandrel 2 (blocking screw mandrel 2 inclined-plane guide frame); Because screw mandrel 2 is stuck, and screw mandrel 2 has inclined-plane navigation designing above, and therefore screw knob 1 can only be rotated rise by user in use, and due to threaded function, screw knob 1 can rise arbitrary height according to user intention.After mixing up, directly pressed by screw knob 1, complete injection, because buckle 3 blocks screw mandrel 2 inclined-plane guide frame instead of screw thread place, therefore screw mandrel 2 carries out injection propelling easily through buckle 3; When needing to change dressings, directly taken down by medicine bottle 4, then buckle 3 can return to initial conditions, now screw mandrel 2 can be reversely rotated rollback and go back, to use next time.
The foregoing is only specific embodiments of the invention, be not limited to the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
