It is big that utility model content the purpose of this utility model is to provide a kind of sorption extraction testing sample scope, makes full use of sample substrate, improves the effect of sorption extraction, protects fiber head, reduces the fiber head solid-phase micro-extracting device of cost.
This utility model specifically includes that extraction equipment shell, annular chassis, contiguous block, fan blades, spring base, hollow axle, gear A, gear B, motor, fixing needle tubing, depression bar, cylindrical rubber resistance plug, fiber head, strip groove, cylindrical connecting rod and spring. Wherein, extraction equipment shell is the transparent cylindrical housing of upper and lower opening, and the lower end of extraction equipment shell is fixing connects annular chassis. Being provided with contiguous block in the inside of extraction equipment shell, contiguous block is hollow cylindrical, and the bottom of contiguous block connects some fan blades by articulate, it is desirable to the bottom of contiguous block connects three fan blades by articulate. The medial wall of each fan blades is respectively fixedly connected with a spring base. The hollow axle of the middle part grafting upper and lower opening of contiguous block, the external diameter of hollow axle is less than the annular diameters of annular chassis. Being socketed gear A on hollow axle, gear A is placed in the top of contiguous block, and gear A is meshed with gear B. The output shaft of grafting motor in the middle part of gear B. Being provided with fixing needle tubing in above-mentioned hollow axle, fixing needle tubing is cylindrical shell, at the external diameter of this fixing needle tubing less than the internal diameter of hollow axle. The upper end of fixing needle tubing is provided with depression bar, and the upper end grafting cylindrical rubber resistance plug of depression bar, the external diameter of cylindrical rubber resistance plug is identical with the internal diameter of extraction equipment shell. This depression bar extends to the outside of hollow axle upper end, and the lower end of fixing needle tubing is provided with fiber head, and this fiber head extends to the outside of hollow axle lower end.On the outer wall of fixing needle tubing, it is provided with some vertical strip grooves, it is desirable on the outer wall of fixing needle tubing, is provided with three vertical strip grooves. Each groove medial wall is respectively equipped with the cylindrical connecting rod of level, the outside of each cylindrical connecting rod is socketed spring respectively, one end of this spring is socketed in the outside of cylindrical connecting rod, and the other end of spring is connected with the spring base on the medial wall of corresponding fan blades.
This utility model is in use, upwards take off cylindrical rubber resistance plug, press down on bar, treat that fiber head is placed in the outside of hollow axle, when extending to extraction equipment shell lower end outside, contiguous block being placed on the lower end of hollow axle, the other end of spring is socketed on the spring base of corresponding fan blades medial wall, installs cylindrical rubber resistance plug. The output shaft driven gear B of driven by motor rotates, and gear B engages with gear A, and gear A drives hollow axle to rotate, and the contiguous block on hollow axle also rotates with, thus driving flabellum to rotate. Sample to be extracted substrate is allocated until balancing at fixing phase coating and sample room, stops flabellum and rotates, fiber head inserts the injection port of relevant analytical tool, completes to resolve.
This utility model compared with prior art has the advantage that sorption extraction testing sample scope is big, makes full use of sample substrate, improves the effect of sorption extraction, protects fiber head, reduces cost.
