Abstract
The utility model discloses a needle filling component which comprises a needle tube sleeve and a needle tube nested in the needle tube sleeve. One end of the needle tube sleeve is provided with a first inner hole which closely attaches to and is matched with the outer wall of the needle tube. The other end of the needle tube sleeve is provided with a second inner hole. The second inner hole is communicated with the first inner hole and the diameter of the second inner hole is larger than that of the second inner hole. A flaring part which closely attaches to and is matched with the inner wall of the second inner hole is disposed at an inlet end of the needle tube. The needle filling component is convenient to clean, free of pollution, less prone to pollution generation and cross infection, and the like.
Description
Technical field
The utility model relates generally to food, medical packaging mechanical field, refers in particular to a kind of filling needle assemblies.
Background technology
As shown in Figure 1, existing filling needle assemblies generally is made up of needle tubing cover 1 and needle tubing 2, and needle tubing cover 1 adopts bar elder generation processing endoporus to process outside face to required form then and forms.Because needle tubing cover 1 is longer, during the processing endoporus, once boring can't drill through, and generally adopts in twice boring in bar two ends; Namely earlier get out the hole adaptive with needle tubing 2 at an end of bar, the other end boring at bar connects with it then.When the other end boring of bar, to stagger for fear of holing with the first time, the general employing than the brill flower of holing bigger for the first time makes the profile of holing contain the profile of boring for the first time.During assembling, the arrival end 21 that makes needle tubing 2 penetrates from the big nose end of needle tubing cover 1, and makes arrival end 21 end faces of needle tubing 2 concordant with the small bore end end face of needle tubing cover 1, then with concordant both ends of the surface joint place employing laser welding.But, there is bigger slit between the big nose end of needle tubing cover 1 and needle tubing 2 outer walls, if not with this gap closing, so in the use of irritating needle assemblies, untight slit is easy to generate hydrops, and is residual dirty, and is difficult to clean up, pollute and cross pollution thereby produce, do not meet the requirement of new edition GMP.If adopt the laser welding sealing, because the wall thickness of needle tubing 2 is only about 0.25mm, the material of the 316L(needle tubing cover that wlding is fused into) temperature of liquid metal surpasses 1400 ℃ (fusing point of 316L), when it fills this slit, can and penetrate the needle tubing wall with thin-walled needle tubing instant melting, make needle tubing destroyed.Existing processing method generally is to adopt low-melting wlding, be lower than 800 ℃ of solderings, although needle tubing can not destroyed by burn through, but the composition of weighting material is not corrosion-resistant steel 316L, weighting material does not possess good anti-corrosion and rust-preventing characteristic, easily with soup generation chemical reaction, the risk of pollution soup is very big, does not meet the GMP requirement.
The utility model content
The technical problems to be solved in the utility model is: at the deficiency that prior art exists, provide a kind of and be convenient to clean, do not shelter evil people and countenance evil practices, be difficult for producing the filling needle assemblies of pollution and cross pollution.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of filling needle assemblies, comprise the needle tubing cover and be sheathed on the interior needle tubing of needle tubing cover, one end of described needle tubing cover is provided with the needle tubing outer wall and is adjacent to first endoporus that cooperates, the other end of described needle tubing cover offer connect with first endoporus and diameter greater than second endoporus of first endoporus, the arrival end of described needle tubing is provided with the second endoporus inwall and is adjacent to the expansion mouth that cooperates.
Irritate the further improvement of needle assemblies as the utility model:
The place of being adjacent to of described needle tubing cover two ends and needle tubing all welds fixing.
The place of being adjacent to of described needle tubing cover two ends and needle tubing is provided with the weld seam that laser welding forms.
It is concordant that arrival end end face and the needle tubing of described needle tubing overlaps the end face of the second endoporus place end.
Described expansion mouth is taper.
Compared with prior art, advantage of the present utility model is: filling needle assemblies of the present utility model, the arrival end of its needle tubing are provided with the expansion mouth that is adjacent to the second endoporus inwall, so that welding; Adding that the first endoporus place end itself just is adjacent to needle tubing cooperates, can directly weld, thereby make needle tubing cover two ends all can with the needle tubing welded seal, make and reach seamless sealing state between needle tubing cover and the needle tubing, thereby be convenient to clean, do not shelter evil people and countenance evil practices, be difficult for producing and pollute and cross pollution, meet the requirement of new edition GMP.

Marginal data: 1, needle tubing cover; 11, first endoporus; 12, second endoporus; 2, needle tubing; 21, arrival end; 22, exit end; 23, expansion mouth.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is described in further detail.
As shown in Figure 2, filling needle assemblies of the present utility model, comprise needle tubing cover 1 and be sheathed on needle tubing and overlap 1 interior needle tubing 2, one end of needle tubing cover 1 is provided with needle tubing 2 and is adjacent to first endoporus 11 that cooperates, the other end of needle tubing cover 1 offer connect with first endoporus 11 and diameter greater than second endoporus 12 of first endoporus 11, and the circumferential profile of second endoporus 12 contains the circumferential profile of first endoporus 11.The arrival end 21 of needle tubing 2 is provided with second endoporus, 12 inwalls and is adjacent to the expansion mouth 23 that cooperates, and in the present embodiment, expansion mouth 23 is taper, can adopt the enlarging mould enlarging of taper to form, and is easily manufactured.
In the present embodiment, the place of being adjacent to that needle tubing overlaps 1 two ends and needle tubing 2 all welds fixing, it is fixing to be that the place of being adjacent to of expansion mouth 23 and second endoporus, 12 inwalls and the place of being adjacent to that needle tubing overlaps 1 first endoporus, 11 place ends and needle tubing 2 outer walls all weld, and needle tubing is overlapped reach seamless sealing state between 1 two ends and the needle tubing 2.In the present embodiment, the place of being adjacent to that needle tubing overlaps 1 two ends and needle tubing 2 adopts laser welding, and the place of being adjacent to that needle tubing overlaps 1 two ends and needle tubing 2 is provided with the weld seam that laser welding forms.
In the present embodiment, it is concordant that arrival end 21 end faces and the needle tubing of needle tubing 2 overlaps the end face of 1 second endoporus, 12 place ends, so that welding.
Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to above-described embodiment, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
