Abstract
The utility model discloses a kind of sample injector of continuous and quantitative, comprise syringe and propeller, described syringe inwall uniform intervals is distributed with some dome-type salient points, described propeller comprises push rod and piston, it is inner that described push rod is located at described syringe in mobilizable mode, described piston is located at the front end of described push rod, and described piston outer periphery is annular fan-shaped tangent plane, and described piston is positioned on described salient point.The utility model, by arranging uniform salient point at syringe inwall, makes sample injector realize the operation of continuous and quantitative, strengthens the stability of loaded sample, and improve operating efficiency.
Description
Technical field
The utility model belongs to the technical field of sample injector, particularly relates to a kind of sample injector of continuous and quantitative.
Background technology
Sample injector, be widely used in biology at present, the laboratories such as food, or in enterprise, as sample adding device, application of sample can be carried out to liquid rapidly, at present, the design of sample injector, be provided with scale at syringe outer wall, when needs are quantitative, pressing propeller completes quantitative work to the scale of specifying, but when reality uses, must very careful operation, because propeller is in the process advanced, the scale of specifying likely can be exceeded, or be also less than the scale of specifying, exert a certain influence to the stability of production batch.
In view of this, the present inventor studies and devises a kind of sample injector of continuous and quantitative, and this case produces thus.
Utility model content
The purpose of this utility model is the sample injector providing a kind of continuous and quantitative, by arranging uniform salient point at syringe inwall, makes sample injector realize the operation of continuous and quantitative, strengthens the stability of loaded sample, and increases work efficiency.
In order to solve above-mentioned purpose, the technical scheme that the utility model adopts is:
A kind of sample injector of continuous and quantitative, comprise syringe and propeller, described syringe inwall uniform intervals is distributed with some dome-type salient points, described propeller comprises push rod and piston, it is inner that described push rod is located at described syringe in mobilizable mode, described piston is located at the front end of described push rod, and described piston outer periphery is annular fan-shaped tangent plane, and described piston is positioned on described salient point.
As the preferred embodiment of embodiment, the material that described syringe adopts is transparent material.
As the preferred embodiment of embodiment, outside described syringe, indicate the scale for measuring.
Because the sample injector of a kind of continuous and quantitative of the utility model have employed above-mentioned technical scheme, namely syringe and propeller is comprised, described syringe inwall uniform intervals is distributed with some dome-type salient points, described propeller comprises push rod and piston, it is inner that described push rod is located at described syringe in mobilizable mode, described piston is located at the front end of described push rod, and described piston outer periphery is annular fan-shaped tangent plane, and described piston is positioned on described salient point; The utility model by arranging uniform salient point at syringe inwall, can be made sample injector realize the operation of continuous and quantitative, strengthening the stability of loaded sample, and improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of sample injector of continuous and quantitative, comprise syringe 1 and propeller 2, described syringe 1 inwall uniform intervals is distributed with some dome-type salient points 11, described propeller 2 comprises push rod 21 and piston 22, and it is inner that described push rod 21 is located at described syringe 1 in mobilizable mode, and described piston 22 is located at the front end of described push rod 21, described piston 22 periphery is annular fan-shaped tangent plane, and described piston 22 is positioned on described salient point 11.
As the preferred embodiment of embodiment, the material that described syringe 1 adopts is transparent material.
As the preferred embodiment of embodiment, outside described syringe 1, indicate the scale for measuring.
When using the utility model structure, syringe needle point is injected and treats, in the liquid of application of sample, propeller to be pulled outward, treat that sample adding liquid body is sucked in barrel chamber, during application of sample, pressing propeller, treat that sample adding liquid body is extruded out in syringe, when being pushed into first salient point, producing screens, quantitatively adding liquid, continue propelling and can cross this salient point, arrive second salient point and produce screens, again quantitatively add liquid, so until liquid is added.The operation of the utility model continuous and quantitative, strengthens the stability of loaded sample, and improves operating efficiency.
The above, be only the utility model preferred embodiment, therefore the scope that the utility model implements can not be limited successively, the equivalence namely done according to the utility model the scope of the claims and description change with modify, all should still belong in scope that the utility model contains.
