Description

Technical Field

[0001] This utility model relates to the field of food safety testing, and in particular to a fixing mechanism for food safety testing tubes. Background Technology

[0002] Food safety testing involves detecting harmful substances in food according to national standards. It relies on basic theories of physics, chemistry, and biochemistry, as well as various technologies, and follows established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products to ensure product quality compliance. Food testing requires sampling of the food being tested.

[0003] Currently, food safety testing requires batch sampling of food from the production line. The sampled food is placed in test tubes and sent to the testing center for quality testing. Because the number of test tubes for food sampling testing is large, the traditional fixed mechanism for food safety testing test tubes is very inconvenient to handle and transport, thus affecting testing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing food safety testing tube fixing mechanisms, which are inconvenient for handling and transporting test tubes, and to propose a fixing mechanism for food safety testing tubes.

[0014] 1. In this utility model, by setting four test tube placement boxes on the trolley, it is convenient for the testing personnel to push the trolley along the food production line to extract food and store it into test tubes. When in use, the positions of the upper test tube placement box and the lower test tube placement box are interchanged. When the positions are interchanged, the test tube placement boxes are kept balanced by the balancing component, so that the test tube placement boxes always face upwards, keeping the test tubes stable, increasing the test tube storage capacity, and making it convenient for the testing personnel to pick up the test tubes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: This example provides a fixing mechanism for food safety test tubes. See [link to example]. Figure 1-4 Specifically, it includes a trolley 1, with fixed plates 11 fixed at both ends of the trolley 1, a fixed shaft 12 fixed in the middle of the fixed plate 11, two rotating rollers 13 symmetrically rotating on the fixed shaft 12, two pairs of support rods 14 symmetrically mounted on each of the rotating rollers 13, and a round shaft 15 rotatably mounted on the inner side of each support rod 14. A test tube placement box 16 is fixed at the end of the round shaft 15, and multiple round grooves are opened on the test tube placement box 16, with rubber pads at the bottom of the round grooves. The trolley 1 is equipped with a balancing component to keep the test tube placement box 16 balanced, and a positioning component to fix the rotating rollers 13.

[0024] By setting four test tube placement boxes 16 on the trolley 1, it is convenient for testing personnel to push the trolley 1 along the food production line to extract and test food. The extracted food is placed into test tubes, which are then inserted into the circular grooves on the test tube placement boxes 16. By rotating the rotating roller 13 along the fixed shaft 12, the upper and lower test tube placement boxes 16 are swapped. During the position swap, the test tube placement boxes 16 are kept balanced by a balancing component, so that the test tube placement boxes 16 always face upwards. This ensures that the sampled food in the test tubes and the test tubes themselves will not fall out, increasing the test tube storage capacity while making it convenient for testing personnel to retrieve the test tubes.

[0025] In the specific implementation process, such as Figure 2 and Figure 4 As shown, the balancing assembly includes a rotating shaft 2 rotatably mounted on one side of the support rod 14. A drive gear 21 is fixedly mounted on the rotating shaft 2. Two fixed gears 22 that mesh with the drive gear 21 are fixedly mounted on the fixed shaft 12. A rotating wheel 23 is fixedly mounted on both the rotating shaft 2 and the round shaft 15. A belt 24 is fitted on the rotating wheel 23. The drive gear 21 and the fixed gears 22 are the same size.

[0026] When the rotating roller 13 rotates along the fixed shaft 12, the support rod 14 will drive the round shaft 15 and the rotating shaft 2 to move synchronously. The drive gear 21 on the rotating shaft 2 will rotate along the fixed gear 22. The rotation of the drive gear 21 will drive the rotating shaft 2 to rotate. The rotating shaft 2 drives the round shaft 15 to rotate through the rotating wheel 23 and the belt 24. The round shaft 15 drives the test tube placement box 16 to rotate synchronously, so that the test tube placement box 16 and the rotating roller 13 rotate in opposite directions, so that the opening of the test tube placement box 16 always faces upward and maintains balance.

[0027] In the specific implementation process, such as Figure 2 and Figure 3 As shown, the positioning assembly includes a rod 3 inserted into the fixed plate 11. Four slots 31 are symmetrically opened on one edge of the rotating roller 13. One end of the rod 3 is inserted into two slots 31. A spring 32 is sleeved on each rod 3. A retaining ring 4 is fixed on the rod 3. One end of the spring 32 is in contact with one side of the retaining ring 4, and the other end of the spring 32 is in contact with the inner side of the fixed plate 11.

[0028] The slots 31 are arranged in a cross shape, while the insertion rod 3 is concave. The insertion rod 3 is pushed by the spring 32, so that the end of the insertion rod 3 is inserted into the two slots 31 to fix the rotating roller 13 and improve the stability of the rotating roller 13.

[0029] In the specific implementation process, such as Figure 2 and Figure 4 As shown, a semi-circular weight 5 is fixed at the center of the lower surface of the test tube placement box 16; the weight 5 increases the bottom position of the test tube placement box 16, further increasing the stability of the test tube placement box 16.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
