Description

Technical Field

[0001] This utility model relates to the field of sample testing technology, and in particular to a food testing sample storage device. Background Technology

[0002] Food testing involves detecting harmful substances in food according to national standards, primarily analyzing harmful and toxic indicators such as heavy metals and aflatoxin, to ensure food quality and safety and compliance with relevant standards and regulations. In addition to regular sampling inspections by regulatory authorities, food manufacturers also need to conduct safety tests on food produced on their production lines. Food testing requires sampling, storing the samples in test tubes or glass bottles, and then placing the containers in a storage box for unified storage. This ensures the representativeness of the collected samples and the accuracy of subsequent test results. Existing sample storage devices typically use a perforated fixing plate to limit the upper part of the test tube, with the bottom of the test tube resting directly on a base. This method cannot reliably secure the test tube and is not suitable for test tubes of different diameters, limiting its applicability. Utility Model Content

[0003] The technical problem this invention aims to solve is that existing sample storage devices generally use a fixed plate with holes to limit the upper part of the test tube, and the bottom of the test tube is placed directly on the base, which cannot securely fix the test tube and is not suitable for test tubes of different diameters, thus having a limited range of applications.

[0004] To address the aforementioned issues, this utility model provides a food testing sample storage device. The device includes a horizontal plate inside the box, with multiple placement holes spaced apart on the horizontal plate. Multiple elastic support plates are spaced apart along the circumference of each placement hole. An arc-shaped plate is rotatably mounted on the bottom plate of the box, and multiple arc-shaped plates are spaced apart along the circumference of the placement holes. An elastic element is provided between the arc-shaped plate and the bottom plate of the box, allowing the outer side of the arc-shaped plate to remain open.

[0005] The food testing sample storage device provided by this utility model also has the following technical features:

[0006] The bottom plate of the box is provided with a support base, and the middle of the arc plate is integrally formed with a rotating shaft. The end of the rotating shaft is rotatably connected to the support base, and the elastic element is a torsion spring sleeved on the rotating shaft.

[0007] The surfaces of the arc-shaped plate and the support base are equipped with locking posts to limit the two ends of the torsion spring.

[0008] The concave surface of the arc-shaped plate faces upward and is provided with multiple raised pads at intervals.

[0009] The elastic support sheet is fan-shaped and made of rubber or silicone.

[0010] The end of the horizontal plate is provided with a sliding rod, and the inner wall of the box is provided with a vertical groove corresponding to the sliding rod; the outer side of the sliding rod is provided with a groove, and the box is provided with a threaded hole communicating with the vertical groove. A locking bolt is provided in the threaded hole, and the end of the locking bolt can be inserted into the groove.

[0011] This invention has the following advantages: A test tube containing a food sample is inserted downwards through the placement hole until the bottom of the test tube contacts and pushes the inner side of the arc-shaped plate, causing the inner side of the arc-shaped plate to rotate downwards and the outer side inwards until the inner side of the arc-shaped plate contacts the bottom plate of the box and the outer side of the arc-shaped plate contacts the outer surface of the bottom of the test tube, thus supporting and fixing the bottom of the test tube. The elastic support piece inside the placement hole supports the upper part of the test tube, thereby firmly fixing the entire test tube and preventing it from shaking. It is also suitable for test tubes of different diameters, thus expanding its applicability. Attached Figure Description

An elastic member 25 is provided between the arc plate 24 and the bottom plate of the box 10 so that the outer side of the arc plate 24 can remain open.

[0018] Insert the test tube containing the food sample downwards through the placement hole 22 until the bottom of the test tube touches and pushes the inner side of the arc plate 24, causing the inner side of the arc plate 24 to rotate downwards and the outer side to rotate inwards until the inner side of the arc plate 24 touches the bottom plate of the box 10 and the outer side of the arc plate 24 touches the outer surface of the bottom of the test tube, thereby supporting and fixing the bottom of the test tube. The elastic support piece 23 in the placement hole 22 supports the upper part of the test tube, thus firmly fixing the entire test tube and preventing it from shaking. It is also suitable for test tubes of different diameters, thus expanding its applicability.

[0019] The box body 10 has an opening on its upper side and is equipped with a cover plate 11. One side of the cover plate 11 is rotatably connected to the box body 10, and the other end is detachably connected to the box body 10 via a snap-fit.
