[0022] like Figure 1-4As shown, the utility model provides a food safety detection sampling device, including a food detection sampling box 1 and a sample storage column 6 fixedly installed inside the food detection sampling box 1. The upper surface of the sample storage column 6 is provided with a plurality of food sample storage cavities 7. When collecting food samples, the collected food samples can be directly stored inside the food sample storage cavity 7. At this time, the outer periphery of the food sample storage cavity 7 can be made of glass material. In another implementation mode, the food samples can be collected and stored in a test tube, and then the test tube is stored inside the food sample storage cavity 7. In this way, the food sample storage cavity 7 can be The outer periphery is configured to be made of rubber material. At this time, the internal stability of the test tube placed in the food sample storage chamber 7 is higher. An internal thread area 11 is provided on the inner surface of the food detection sampling box 1. The second closing cover 3 is threadedly connected to the internal thread area 11. The bottom end of the second closing cover 3 is rotatably connected with a rotating cover plate 4. After the second closing cover 3 is installed on the top of the food detection sampling box 1, the lower surface of the rotating cover plate 4 is attached to the upper surface of the sample storage cylinder 6 to close the top of all food sample storage chambers 7. A sealing rubber pad can be fixedly installed on the lower surface of the rotating cover plate 4 to improve the sealing of the food sample storage chamber 7 by the rotating cover plate 4. In order to achieve the sealing effect after the sample is collected, a food sample taking and placing notch 5 is provided on the rotating cover plate 4, and the area of the food sample taking and placing notch 5 is larger than the cross-section of the food sample storage cavity 7. After the food sample taking and placing notch 5 is located directly above the food sample storage cavity 7, the top opening of the food sample storage cavity 7 is completely exposed. In the process of collecting food samples and testing food samples, the position of the food sample taking and placing notch 5 can be adjusted by rotating so that the food sample taking and placing notch 5 is located above the corresponding food sample storage cavity 7, and the collected sample is placed in the food sample storage cavity 7 and the food sample is placed in the food sample storage cavity 7 by using the food sample taking and placing notch 5. The samples in the storage cavity 7 are taken out for testing, which avoids the need to open and close the food testing sampling box 1 many times during the process of collecting and testing food samples, which is easy to cause the growth of bacteria, affecting the results of food testing and the safety of food. A first closing cover 2 is detachably provided on the top of the food testing sampling box 1, and an external threaded area 10 is provided on the top of the food testing sampling box 1. The first closing cover 2 is threadedly connected to the external threaded area 10. Under normal conditions, the first closing cover 2 is installed on the top of the food testing sampling box 1 to further improve the sealing effect of the internal cavity of the food testing sampling box 1.
[0023] Furthermore, a collecting clamp placement cavity 9 is opened on the sample storage column 6, and a collecting clamp 12 is stored inside the collecting clamp placement cavity 9. The collecting clamp 12 is used to clamp a cotton ball and dip it into the food sample, and then the food sample is tested. A limiting block 13 is fixedly installed on the top of the collecting clamp 12, and the end of the limiting block 13 is fitted on the edge of the food sample taking and placing notch 5. After the two are fitted, the limiting block 13 can limit the rotation of the rotating cover plate 4 to prevent the rotating cover plate 4 from rotating so that the food sample taking and placing notch 5 is located above the top of the food sample storage cavity 7. A clamping block is rotatably installed on the inner bottom surface of the first closing cover 2. After the first closing cover 2 is installed on the top of the food detection sampling box 1, the clamping block is fitted on the top of the collecting clamp 12 to limit the collecting clamp 12.
[0024] Furthermore, a cotton ball storage cavity 8 for storing cotton balls is provided on the upper surface of the sample storage column 6. When the rotation of the rotating cover 4 is restricted by the limit block 13, the cotton ball storage cavity 8, like all food sample storage cavities 7, is staggered with the food sample taking and placing notch 5.
[0025] Furthermore, a pair of connecting rings are rotatably connected on the outer surface of the food detection sampling box 1, and the two connecting rings are connected by a lifting strap 14. It will be simpler and more convenient to carry the food detection sampling box 1 using the lifting strap 14, and it will be more convenient.
[0026] The above description is only a preferred embodiment of the utility model and does not limit the utility model in any form.
