Description

Technical Field

[0001] This utility model relates to a non-contact sampler for food testing, belonging to the technical field of food sampling and testing equipment. Background Technology

[0002] To ensure public health, food safety is of paramount importance. Therefore, food sampling and inspection are necessary during production. Food testing can help identify and prevent the presence of harmful substances (such as pathogens, chemical contaminants, and heavy metal residues), ensuring consumers can consume safe food.

[0003] However, in existing technologies, during food testing, the food to be tested is moved and handled by the operator's hands. Since hands are used for other tasks, contamination is unavoidable, making it impossible to completely prevent contamination of the food. Therefore, this invention proposes a non-contact sampler for food testing. Utility Model Content

[0004] Based on the above background, the purpose of this utility model is to provide a non-contact sampler for food testing, thereby solving the problems in the background technology.

[0005] This utility model provides the following technical solution:

[0007] Preferably, the linkage assembly includes a set of first hinge plates, a set of second hinge plates, and a hinge rod. The set of first hinge plates is fixedly connected to the center of the bottom of the movable plate, the set of second hinge plates is fixedly connected to the side of the baffle located inside the receiving cavity, and the two ends of the hinge rod are respectively hinged between the set of first hinge plates and the set of second hinge plates via hinge shafts.

[0008] Preferably, the elastic pressing assembly includes a spring and a limiting plug. The top of the inner wall of the outer sleeve is provided with an internal thread, and the outer wall of the limiting plug is provided with an external thread. The internal thread and the external thread are threadedly connected to each other, thereby detachably connecting the limiting plug to the inside of the outer sleeve. The spring is placed between the limiting plug and the movable plate inside the outer sleeve.

[0009] Preferably, the limiting plug is provided with a connecting post at the top, and the connecting post is provided with a turntable at the top.

[0010] Preferably, the bottom of the handle is provided with a groove, and the grip can be moved into the groove.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model discloses a non-contact sampler for food testing. By setting a receiving groove inside the sampling block and hinged a baffle inside the receiving groove, during sampling, the sampler can hold the handle to insert the sampling block into the food to be tested, and then hold the handle upward to drive the movable plate upward. The connecting rod assembly can drive the baffle to block the opening of the receiving groove, keeping the food to be tested inside the receiving groove for sampling, thus preventing food contamination and achieving the purpose of non-contact sampling.

[0020] like Figures 1-2 As shown, a non-contact sampler for food testing includes an outer sleeve 1. A sampling block 2 is provided at the bottom of the outer sleeve 1. An inclined surface 3 is provided on the bottom right side of the sampling block 2. A receiving groove 4 is provided on the inclined surface 3 of the sampling block 2. A through hole 5 communicating with the inner cavity of the outer sleeve 1 is provided on the top surface of the receiving groove 4. A baffle 6 is hinged in the receiving groove 4. The upper part of the baffle 6 is hinged to the inner wall of the receiving cavity near the top. A handle 7 is provided on the outer side of the outer sleeve 1 near the top. A through groove 8 is provided at the bottom of the handle 7 on the outer sleeve 1. A grip 9 is provided in the through groove 8. A groove 18 is provided at the bottom of the handle 7. The grip can be moved into the groove 18. A circular movable plate 10 is movably arranged inside the outer sleeve 1. The movable plate 10 is hinged to the baffle 6 through a connecting rod assembly. An elastic pressing assembly is also provided at the top inside the outer sleeve 1.

[0021] In the above technical solution, by setting a receiving groove 4 inside the sampling block 2 and by hinged baffle 6 inside the receiving groove 4, when sampling, the sampling block 2 can be inserted into the food to be tested by holding the handle 7, and then the handle can be held upward to drive the movable plate 10 to move upward. The connecting rod assembly can be used to drive the baffle 6 to block the opening of the receiving groove 4, and the food to be tested can be blocked in the receiving groove 4 for sampling, so as to prevent food contamination and achieve the purpose of non-contact sampling.

[0022] In this utility model, the connecting rod assembly includes a set of first hinge plates 11, a set of second hinge plates 12, and a hinge rod 13.
