Description
Technical field:
This utility model relates to technical field of medical, is a kind of inadvisable insulin syringe of syringe needle, particularly its bindiny mechanism down that has split type interior needle stand specifically.
Background technology
Generally have the fixedly insulin syringe of needle tubing, being connected of overcoat and needle stand all is integral type, needle stand and overcoat integrated injection molding, needle tubing directly is bonded on the needle stand of overcoat head, the insulin syringe of this structure, because overcoat is very elongated on the structure, needle tubing is tiny (to have only 0.25～0.45mm), during the overcoat injection mo(u)lding, be easy to bending occur, needle stand hole deflection causes the needle tubing deflection, the dress pin hole is one-body molded, cause the pulling force instability of bonding needle tubing easily, this three big defective causes insulin syringe production process fraction defective very high, wastes many social resources, to thoroughly eradicate these defectives, become the insulin syringe production industry and endeavour the difficult problem that solves always.
Summary of the invention:
The purpose of this utility model, be to provide a kind of new have split type in the insulin syringe of syringe needle under needle stand inadvisable, it has solved three big defectives the insulin syringe production process that generally has fixing needle tubing from structure and principle, can improve qualification rate, reduce production costs, save social resources.
To achieve these goals, technical scheme of the present invention is; A kind of inadvisable insulin syringe of syringe needle down that has split type interior needle stand, it mainly comprises: overcoat, split type interior needle stand in the tube neck of overcoat top, needle tubing and bonding needle tubing, overcoat, the colloid of needle stand in split type, the pin medicated cap, core bar and the plug and the tail medicated cap that are loaded on the core bar are formed, it is characterized in that: described overcoat top tube neck endoporus is to be with tapering, and be provided with the glue cup of containing binding agent and do not allow split type needle stand to run out of the positioning step of overcoat, the profile of needle stand is provided with and the identical tapering of tube neck endoporus in split type, and with tube neck endoporus interference fit, the needle stand center is provided with the dress pin hole that adapts with needle tubing in split type, dress pin hole head is provided with horn mouth, needle tubing, outer sleeve cervical region position positioning step and split type needle stand are with can the bonded metal material and bonding the coupling together of bonding agent of plastic material, formation has the colloid of certain intensity, such version makes the endoporus of overcoat cervical region become the needle stand size by original-pack aperture size, increase several times, it is crooked easily to have solved overcoat, two hang-ups of the easy deflection of dress pin hole, the dress pin hole of needle stand in split type, horn mouth, the common sticking pin hole of forming of the positioning step at overcoat top and glue cup, hemisphere with wedge angle, this is that integrated syringe is irrealizable forever.
The colloid of this shape has very strong stretching resistance, and it has solved the third-largest difficult problem of insulin production process.
The utility model discloses a kind of inadvisable insulin syringe of syringe needle down that has split type needle stand.Its structural design novelty, exquisiteness, can effectively solve in the insulin syringe production process Three Difficult Issues that exist at present, its product quality can significantly improve, and production cost can obviously reduce, and saves social resources, in terms of existing technologies, have outstanding substantive distinguishing features and marked improvement.
Description of drawings
Fig. 1. be structural representation of the present utility model.
Fig. 2. be the local enlarged diagram of primary structure of the present utility model.
Among the figure: 1, overcoat, 2, the overcoat cervical region, 3, split type in needle stand, 4, needle tubing, 5, colloid, 6, the pin medicated cap, 7, core bar, 8, plug, 9, the tail medicated cap, 10, the glue cup, 11, positioning step, 12, the dress pin hole, 13, horn mouth.
The specific embodiment:
With reference to the accompanying drawings, this utility model is described further.
This utility model is a kind of new inadvisable insulin syringe of syringe needle down that has split type interior needle stand, as shown in Figure 1, it mainly comprises overcoat 1, overcoat cervical region 2, split type interior needle stand 3 in the tube neck, needle tubing 4, the colloid 5 of bonding needle tubing and overcoat and split type interior needle stand, pin medicated cap 6, core bar 7, plug 8 on the core bar and tail medicated cap 9 are formed, it is characterized in that: described overcoat cervical region endoporus is opened greatly, built-in split type interior needle stand, tube neck endoporus has tapering, tapering should be less than 4 °, position and press-fit fixing freely falls when being convenient to assemble split type needle stand, the cervical region inner orifice is provided with the glue cup 10 of containing glue and does not allow split type needle stand to run out of the positioning step 11 of overcoat, the profile of its split type needle stand is provided with and the identical tapering of tube neck endoporus, and with tube neck endoporus interference fit, the magnitude of interference is no more than 0.25mm, and the needle stand center is provided with the dress pin hole 12 that adapts with the needle tubing external diameter in split type, dress pin hole head is provided with horn mouth 13, needle tubing, overcoat cervical region positioning step and split type in needle stand with can the bonded metal material and the binding agent of plastic material be bonded together, formation has the colloid of certain intensity, and then the pin medicated cap is gone up in assembling, core bar and plug and tail medicated cap have been complete insulin syringes.
In the specific implementation, overcoat cervical region tube neck endoporus has tapering, tapering should be less than 4 °, the profile of split type needle stand is provided with and the identical tapering of tube neck, and overall dimensions and tube neck endoporus interference fit, interference fit is no more than 0.25mm, tube neck endoporus is provided with positioning step, such setting, be convenient to freely fall when split type interior needle stand is assembled position and the location positioning that press-fits the split type interior needle stand in back, because the frictional force that the positioning action of positioning step and interference fit produce, needle stand can not come off and be shifted when viscose glue not in split type, the needle stand center is provided with the dress pin hole that adapts with the needle tubing external diameter and horn mouth and links together with overcoat neck tube endoporus oral area glue cup in split type, form a complete dress pin hole, the dress pin hole becomes the hemisphere bodily form of band wedge angle, and it also is the hemisphere bodily form of band wedge angle that adhesive is filled the colloid profile that the back forms, and can increase more than 50% than the colloidal stretching resistance of the hemisphere bodily form of the band fillet of present technology.Split type owing to applying mechanically outward, constitute by overcoat and split type interior needle stand, the pin hole of overcoat top tube neck endoporus and prior art relatively increases several times, core also increases several times in the mould of injection mo(u)lding, reduced the difficulty of outer sleeve forming, be not easy bending, the dress pin hole also has been not easy deflection.This utility model can effectively solve overcoat bending in the present disposable sterilized insulin syringe production process, needle point deflection, the unsettled Three Difficult Issues of stretching resistance (the bonding firmness of needle point), improve qualification rate, reduce production costs, save social resources, in terms of existing technologies, has marked improvement.
