Description

Technical Field

[0001] The utility model relates to the technical field of samplers, in particular to a testing sampler. Background Art

[0002] A sampler is a tool or device used to obtain a small sample from a larger volume of a substance. Samplers are often used in scientific experiments, industrial production, medical testing and other fields. Their purpose is to ensure that a representative sample is obtained from a large volume of a substance for analysis, testing or quality control.

[0003] For example, a Chinese utility model patent (CN220872103U) discloses a food inspection and testing sampler, which records: "The threaded sleeve can drive the threaded push rod to push into the sampling drill barrel, so that the taken sample can be gradually pushed out through the push plate. Since the threaded push rod can be completely pulled out of the sampling drill barrel, the sampling space occupied inside the sampling drill barrel is greatly reduced. Moreover, when pushing out the material, the movable drill can be reversed without manual operation, thereby improving the convenience of sampling." It also records: "The food inspection and testing sampler has a technical problem that the push rod occupies a certain space inside the sampler body, affecting the maximum sampling depth. At the same time, the screw rod needs to be manually rotated when pushing out the sample, which is inconvenient to operate."

[0004] To sum up the above, it can be known that in the prior art, an electric drill is used to drive the sampling sleeve to rotate and cooperate with a threaded push rod to achieve the effect of using a push plate to push out the sample in the sampling sleeve. However, this method has the following technical problems: during the actual sampling process, the rotating sampling sleeve contacts the sample for sampling, which will cause sample residue to splash. This part of the residue may cause damage to the operator's skin and eyes, etc., which is not conducive to actual use. For this reason, the present application proposes a test sampler to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content

[0005] Based on this, it is necessary to provide an inspection and detection sampler to address the above technical problems. The opening of the protective tube is pressed against the surface of the sample, and the driving motor is controlled to drive the sampling tube to rotate, so that the sample can be cut and sampled. The rotation of the sampling tube will also drive the moving block to move toward the grasping block under the restriction of the limiting rod, so that the protective tube and the sampling tube are relatively displaced. In the process of the sampling tube extending into the interior of the sample, the protective tube is always kept against the outside of the sample to avoid splashing of sample residues during the sampling process and causing damage to the eyes or skin of the sampler, thereby improving the safety of the use of the device and the practicality of the device. Pulling the protective tube can separate the protective tube from the moving block, which is convenient for the user to clean the sample residues on the inner wall of the protective tube and the bristles, reducing the difficulty of later maintenance of the device.

[0028] As described in the background art, during the actual sampling process of the device, when the rotating sampling sleeve contacts the sample for sampling, sample residue may splash, which may cause damage to the operator's skin and eyes, etc., and is not conducive to actual use.

[0029] Specifically, please refer to Figure 1-Figure 2 , the inspection and testing sampler specifically includes:

[0030] A gripping block 1, on which a protection mechanism 3 is provided, a driving motor 2 is fixedly mounted on the gripping block 1, an output end of the driving motor 2 is fixedly connected to a sampling tube 4, and the sampling tube 4 is rotatably connected to the inner wall of the gripping block 1;

Pulling the protective tube 7 can separate the protective tube 7 from the moving block 5, which is convenient for the user to clean the sample residues on the inner wall of the protective tube 7 and the bristles 13, reducing the difficulty of later device maintenance.

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] Embodiment 1:

[0035] Please refer to Figure 5-Figure 6 , a test sampler, comprising:

[0036] The anti-splash component includes a limiting spring 9, and a plurality of limiting springs 9 are fixedly connected to the inner wall of the moving block 5. The end of the limiting spring 9 close to the central axis of the moving block 5 is fixedly connected to a limiting plate 10.

[0038] Through the above structural design, the opening of the protective tube 7 is pressed against the surface of the sample, and then the driving motor 2 is controlled to drive the sampling tube 4 to rotate, so that the sample can be cut and sampled. The rotation of the sampling tube 4 will also drive the moving block 5 to move toward the grasping block 1 under the restriction of the limiting rod 6, so that the protective tube 7 and the sampling tube 4 are relatively displaced, and then in the process of the sampling tube 4 extending into the interior of the sample, the protective tube 7 is always kept against the outside of the sample. In this process, the sample residues generated by the sampling tube 4 when cutting the sample will splash outward and then be blocked by the protective tube 7. After the sampling of the device is completed, the sample residues inside the protective tube 7 can be cleaned, and the protective tube 7 and the moving block 5 can be pulled to both sides respectively, so that The block 8 on the protective tube 7 squeezes the limiting block 11, forcing the limiting block 11 to slide toward the inside of the moving block 5. During this process, the limiting plate 10 slides toward the position of the limiting spring 9, and the limiting spring 9 is deformed accordingly. Then, as the protective tube 7 continues to be pulled, the block 8 can be allowed to leave the restriction of the limiting block 11, and then, under the action of the elastic force of the limiting spring 9, the limiting plate 10 and the limiting block 11 can be driven to slide a certain distance toward the center axis of the moving block 5, and then the inside of the protective tube 7 and the sample residues on the bristles 13 can be cleaned. After cleaning, the block 8 on the protective tube 7 is inserted into the appropriate position in the moving block 5, and the protective tube 7 is pushed so that the limiting block 11 is stuck in the inside of the block 8.

[0042] The auxiliary component includes a rubber pad 15, and the side of the protective tube 7 away from the moving block 5 is fixedly connected with the rubber pad 15. The rubber pad 15 may be provided with textures to adapt to temperature changes. The end of the protective tube 7 away from the moving block 5 is detachably connected to the protective cover 14 through threads.

[0043] Through the above-mentioned structural design, after the sample is cut into the inside of the sampling tube 4, the opening of the sampling tube 4 is aligned with the place where the sample is placed, and then the driving motor 2 is controlled to drive the sampling tube 4 to rotate in the opposite direction, so that the protective tube 7 moves to the position of the opening of the sampling tube 4, and then the pressure of the retaining ring 19 on the connecting rod 18 is released, so that the push plate 16 moves to the opening of the sampling tube 4 under the action of the elastic force of the reset spring 20, and then the sample inside the sampling tube 4 can be squeezed to the place where the sample is placed, and then after the device is used and cleaned, the protective cover 14 can be closed on the protective tube 7 through the threaded cover.
