[0002] The "Food Safety Operation Specifications for Catering Services" stipulates that food samples should be placed in cleaned and disinfected sealed special containers according to their variety, and stored in special refrigerated facilities at 4°C for 48 hours. The sample quantity of each variety should meet the inspection needs and be no less than 100g. The name of the sample food, sample quantity, sample time, sample retention personnel, and review personnel should be recorded to facilitate the inspection of stored food after a food poisoning accident occurs, to promptly identify the cause of the food poisoning accident, and to provide a basis for rapid treatment. However, there are no special refrigeration facilities during field training, and the food will be moved at any time, which is not conducive to the retention of food samples. Therefore, a portable refrigerated sample box is specially designed;

[0003] The existing sample box can only accommodate sample tubes of a specific diameter. When the diameter of the sample tube to be assembled changes, the sample box needs to be specially matched again. This will cause the staff to prepare sample boxes of various specifications for backup, which is inconvenient to use. Utility Model Content

[0026] like Figure 1-Figure 3As shown, a portable refrigerated sample box includes a refrigerated box body 1, a limiting frame 2 is fixedly installed on the inner wall of the refrigerated box body 1, and a first curved plate 21 is provided inside the limiting frame 2, which is characterized in that: multiple groups of support bars 22 are fixedly installed inside the limiting frame 2, the first curved plate 21 is fixedly connected to one side of the support bar 22, two support rods 3 are provided on the top of the limiting frame 2, and movable bars 31 corresponding to the number of support bars 22 are fixedly installed between the two support rods 3, and the distance between two adjacent movable bars 31 is equal to the distance between two adjacent support bars 22, and a second curved plate 32 corresponding to the first curved plate 21 is fixedly installed on one side of the movable bar 31, and multiple threaded holes 4 are opened on both sides of the top of the limiting frame 2 and located in the center, and the threaded holes 4 are evenly spaced along the length direction of the support rod 3 toward the opening of the first curved plate 21, and an ear plate 33 is fixedly installed on one side of the support rod 3, and the ear plate 33 is fixedly connected to the limiting frame 2 by a screw threaded connection with the threaded hole 4.

[0027] like Figure 2 and Figure 3 As shown, the left movable bar 31 and the second left support bar 22 are in an overlapping correspondence relationship.

[0028] Specifically, the distance between the first curved plate 21 and the second curved plate 32 can be guaranteed to the maximum extent, thereby increasing the maximum value of the diameter of the sampling tube that the device can accommodate.

[0029] like Figure 2 and Figure 3 As shown, an extension plate 5 is fixedly installed at the center of the opening ends of the first arc plate 21 and the second arc plate 32.

[0030] Specifically, the extension plate 5 can enhance the longitudinal limiting capability, while ensuring the limiting capability between the first arc plate 21 and the second arc plate 32 that are vertically staggered.

[0031] like Figure 3 As shown, a buffer rubber strip is fixedly installed on one side of the first curved plate 21, the second curved plate 32 and the extension plate 5.

[0032] Specifically: Increase cushioning and effectively protect the sampling tube.

[0033] like Figure 2 and Figure 3 As shown: slide plates 14 are fixedly installed on both sides of the top of the limit frame 2, and a sliding groove 15 adapted to the slide plates 14 is opened on one side of the support rod 3.

[0034] Specifically, it makes it easier to move the support rod 3 and increases the stability of the connection between the support rod 3 and the limit frame 2.

[0035] Example 2

[0036] like Figure 1and Figure 4 As shown: a bottom plate 11 is provided at the bottom inner side of the refrigerated box body 1, the width of the bottom plate 11 is less than the height between the bottom of the limit frame 2 and the bottom end of the inner wall of the refrigerated box body 1, and a raising plate 12 is fixedly installed on both sides of the top end of the bottom plate 11 along its length direction, and a positioning plate 16 of the same width is fixedly installed at the bottom end of the bottom plate 11 at the corresponding position of the raising plate 12, and a positioning groove adapted to the width of the raising plate 12 and the positioning plate 16 is provided at the bottom of the inner wall of the refrigerated box body 1, and the height of the raising plate 12 is greater than the height of the positioning plate 16.

[0037] Specifically, the positioning groove and the positioning plate 16 can prevent the bottom plate 11 from shifting forward and backward, and the positioning groove and the heightening plate 12 can also prevent the bottom plate 11 from shifting forward and backward.

[0038] like Figure 2 、 Figure 3 and Figure 4 As shown: conical grooves 13 are provided at the top and bottom ends of the bottom plate 11. The number of conical grooves 13 on one side is equal to the number of the first curved plate 21. The center of the bottom circle of the conical groove 13 is located at the midpoint of the running trajectory of the center point between the first curved plate 21 and the second curved plate 32.

[0039] Specifically, the sampling tubes with different diameters can be minimized from tilting when they are limited by the first curved plate 21 and the second curved plate 32 .

[0040] Principle of use: A limiting space is formed between the first curved plate 21 and the second curved plate 32. When the sampling tube is placed therein, it can be firmly limited and prevented from falling. When the sampling tube is thin, loosen the screws to separate the ear plate 33 from the limiting frame 2, then move the support rod 3 to drive the movable bar 31 to move the second curved plate 32 closer to the first curved plate 21, thereby reducing the distance between the first curved plate 21 and the second curved plate 32. Finally, re-tighten the screws to fix the ear plate 33. At this time, the sampling tube with a smaller diameter can be placed. Conversely, when the sampling tube is thicker, repeat the above operation and move the ear plate 33 in the opposite direction.

[0041] When the sampling tube is short, the bottom plate 11 can be flipped over so that the heightened plate 12 contacts the bottom end of the interior of the refrigerated box 1, thereby changing the distance between the first curved plate 21 and the second curved plate 32 and the bottom plate 11, so that when the sampling tube falls on the top of the conical groove 13, the top of the sampling tube can be located within the limited space between the first curved plate 21 and the second curved plate 32.

[0042] The foregoing description is merely a detailed description of specific embodiments of the present invention, intended to enable those skilled in the art to understand and implement the present invention.
