Abstract
The utility model relates to an improved structure of a disposable sample-adding tip, which comprises a sample-adding tube. The sample-adding tube comprises a sample-adding tube head, a sample-adding tube middle part and a sample-adding tube tip part in sequence from the upper part to the lower part; a ring-shaped sealing groove with an external depression is arranged along the circumferential direction of the cavity of the sample-adding tube head; the section of the ring-shaped sealing groove is semicircular; two inward convex rings are arranged along the circumferential direction of the cavity of the sample-adding tube head; and the two convex rings are respectively positioned on the upper side and the lower side of the ring-shaped sealing groove. The structure ensures that an O-shaped rubber sealing ring contacts with the ring-shaped sealing groove and simultaneously contacts with the opposite surfaces of the two convex rings, the contact area of the O-shaped rubber sealing ring and the sample-adding tip is increased, and the upper end of the sample-adding tip is better sealed, thereby the phenomenon of air leakage and liquid leakage is reduced, and the sampling and sample-adding quantity can be effectively controlled.
Description
Technical field
The utility model relates to the structure-improved of disposable application of sample point.
Background technology
Disposable application of sample point is the optimal design that realizes micro-sample dispensing, can be widely used in the distribution of various liquid, comprising: organic liquor, inorganic liquid, mixed liquor, liquid-liquid extraction etc.Disposable application of sample point generally comprises the application of sample pipe, this application of sample pipe comprises application of sample tube head, application of sample pipe middle part and application of sample tip portion from top to bottom successively, described application of sample tube head inner chamber recessed annular seal groove outside it is circumferentially opened, the cross section of this annular seal groove are semicircle.What relatively use always in the prior art is to take a sample and application of sample in conjunction with disposable application of sample point by the sample charging mechanism of full-automatic enzyme non-analysis meter, the sample charging mechanism of full-automatic enzyme non-analysis meter comprises a plurality of liquid-transfering gun heads, the liquid-transfering gun head is corresponding one by one with disposable application of sample point, part rifle head extend in the application of sample tube head inner chamber of disposable application of sample point, be arranged with one " O " type rubber seal on the rifle head, making O-ring seal produce by the axial compression O-ring seal is radially expanded, O-ring seal is stuck in the annular seal groove, thereby make the application of sample point be fixed on the rifle head and form the upper end sealing of application of sample point, and then change by the pressure in the control application of sample point inner chamber and to realize sampling and application of sample.This structure makes O-ring seal produce in the process that is radially expanded in compresses seal; the cross section of " O " type rubber seal becomes oval or irregular closed curve by circle; in fact the contact area of " O " type rubber seal and annular seal groove is less; add rubber seal wearing and tearing in use; therefore; in use leak air and the phenomenon of leakage, cause the amount of sampling and application of sample uncontrollable through regular meeting.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of and is difficult for leaking air and the phenomenon of leakage, can effectively controls the structure-improved of the sampling and the disposable application of sample point of application of sample amount.
The structure-improved of the disposable application of sample point that provides according to the utility model, comprise the application of sample pipe, this application of sample pipe comprises application of sample tube head, application of sample pipe middle part and application of sample tip portion from top to bottom successively, described application of sample tube head inner chamber recessed annular seal groove outside it is circumferentially opened, the cross section of this annular seal groove is semicircle, described application of sample tube head inner chamber is circumferentially with the bulge loop of two convexes along it, and described two bulge loops lay respectively at the upper and lower both sides of described annular seal groove.
The structure-improved of the disposable application of sample point that provides according to the utility model also has following attached technical characterictic:
Described application of sample pipe periphery wall is along being circumferentially with a plurality of bar shaped fins, and the lower surface of described a plurality of fins at grade.
Described application of sample pipe periphery wall is along circumferentially being evenly equipped with six bar shaped fins.
Described application of sample tube head, described application of sample pipe middle part, described application of sample tip portion all are the cone that shrinks gradually from top to bottom, the external diameter of described application of sample tube head lower end is greater than the diameter of upper end, described application of sample pipe middle part, thereby form an annular table terrace, each described fin extends shaping from ring-shaped step towards application of sample pipe middle part.
The structure-improved of the disposable application of sample point that provides according to the utility model compared with prior art has following advantage: described application of sample tube head inner chamber is circumferentially with the bulge loop of two convexes along it, described two bulge loops lay respectively at described annular seal groove on, following both sides, this structure make " O " type rubber seal with basis that annular seal groove contacts on, contact with the opposite face of two bulge loops simultaneously, strengthened the contact area of " O " type rubber seal and application of sample point, make the sealing of application of sample point upper end better, leak air and the phenomenon of leakage thereby reduced, can effectively control sampling and application of sample amount.
Description of drawings
Fig. 1 is a structure cross-sectional schematic of the present utility model.
Fig. 2 is a side-looking enlarged diagram of the present utility model.
Fig. 3 is an A place enlarged diagram among Fig. 1.
Embodiment
Referring to Fig. 1 to Fig. 3, structure improved a kind of embodiment of the disposable application of sample point of the utility model is shown, comprise application of sample pipe 1, this application of sample pipe comprises application of sample tube head 10, application of sample pipe middle part 11 and application of sample tip portion 12 from top to bottom successively, described application of sample tube head, described application of sample pipe middle part, described application of sample tip portion all are the cone that shrinks gradually from top to bottom, the external diameter of described application of sample tube head lower end is greater than the diameter of upper end, described application of sample pipe middle part, thereby forms an annular table terrace 4.Described application of sample tube head inner chamber recessed annular seal groove 2 outside it is circumferentially opened, the cross section of this annular seal groove 2 is semicircle, described application of sample tube head inner chamber is circumferentially with the bulge loop 20 of two convexes along it, and described two bulge loops 20 lay respectively at the upper and lower both sides of described annular seal groove 4.This structure make " O " type rubber seal with basis that annular seal groove contacts on, contact with the opposite face of two bulge loops simultaneously, strengthened the contact area of " O " type rubber seal and application of sample point, make the upper end sealing of application of sample point better, leak air and the phenomenon of leakage, can effectively control sampling and application of sample amount thereby reduced.
