for this we propose a test sample extractor.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a test sample extractor, overcomes the defects of the prior art, and aims to solve the problems of troublesome and time-consuming quantitative sample extraction of the existing straw.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the inspection sample injector comprises a holding rod, an inner cylinder is fixedly arranged in the holding rod, a socket is arranged at the end part of the inner cylinder, a sampling tube is fixedly inserted through the socket, a driving gear is movably connected to one side of the top of the inner cylinder, and a poking wheel coaxial with the driving gear is movably arranged outside the holding rod;

the inner cylinder is internally provided with a lifting rod, the end part of the lifting rod is fixedly connected with a piston, and the outer part of the lifting rod is also sleeved with a return spring.

As a preferable technical scheme of the utility model, tooth grooves meshed with a driving gear are uniformly distributed on one side surface of the lifting rod;

the two ends of the return spring are respectively abutted against the inner side of the end part of the inner cylinder and the top of the piston;

by adopting the technical scheme, the driving wheel can be stirred to drive the coaxial driving gear to push the lifting rod to drive upwards, so that the piston is driven to move in the inner cylinder, and the piston can sink and reset under the action of the reset spring after the driving wheel is loosened.

As a preferable technical scheme of the utility model, the sampling tube is made of PP consumable materials, and the surface of the sampling tube is marked with scales;

through adopting above-mentioned technical scheme, conveniently change the sampling tube, the volume of knowing the extraction sample that simultaneously can be swift.

As a preferable technical scheme of the utility model, a sealing plug is arranged in the socket, and a lug made of hard silica gel is also arranged on the outer side of the end part of the sampling tube;

through adopting above-mentioned technical scheme, through sealing plug seal socket and sampling tube between, prevent that the sample from excessive, utilize the lug to let the sampling tube can block into in the socket simultaneously, prevent that the sampling tube from dropping.

The utility model has the beneficial effects that: the sampling tube consumable is inserted into the socket, the thumb is only required to stir the thumb wheel to drive the piston in the inner tube to move, then the sample is pumped into the sampling tube, the sample is better quantified due to the fact that the thumb is slightly stirred, the sample quantity is rapidly read through the scale in the sampling tube, the thumb is loosened to reset the piston to extrude the sample under the action of the reset spring, the sample is only in the sampling tube, the sample cannot pollute the sample injector, and therefore the sampling operation of various samples can be realized only by replacing the sampling tube consumable, and the practicability is strong.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the present embodiment

Referring to fig. 1-3, the inspection sample extractor comprises a holding rod 1, an inner cylinder 5 is fixedly arranged in the holding rod 1, a socket 9 is arranged at the end part of the inner cylinder 5, a sampling tube 3 is fixedly inserted through the socket 9, a driving gear 4 is movably connected to one side of the holding rod 1 at the top of the inner cylinder 5, and a thumb wheel 2 coaxial with the driving gear 4 is movably arranged outside the holding rod 1;

the inside of inner tube 5 is provided with pull rod 6, and the tip fixedly connected with piston 8 of pull rod 6 still overlaps the outside of pull rod 6 and is equipped with reset spring 7.

In this embodiment, tooth grooves meshed with the driving gear 4 are uniformly distributed on one side surface of the lifting rod 6, two ends of the reset spring 7 respectively abut against the inner side of the end part of the inner cylinder 5 and the top of the piston 8, so that the coaxial driving gear 4 can be driven to push the lifting rod 6 to drive upwards by stirring the driving wheel 2, the piston 8 is driven to move in the inner cylinder 5, and the piston 8 can sink and reset under the action of the reset spring 7 by loosening the driving wheel 2;
