[0002] Food safety testing involves detecting harmful substances in food according to national standards, primarily focusing on harmful and toxic indicators such as heavy metals and aflatoxin. An important aspect of food science and engineering is the introduction and application of chemical unit operations, developing them into food engineering unit operations, thereby promoting the food industry towards large-scale, continuous, and automated production.

[0003] Test tube racks are the most basic experimental instruments in a chemistry laboratory, used to store and dry test tubes. The test tube racks have a corresponding number of small wooden posts and holes.

[0004] However, the existing test tube rack technology has the following shortcomings:

[0005] 1. When sampling samples for food testing, multiple test tube racks are required. However, the existing equipment makes it difficult to connect the test tube racks together. It cannot connect several test tube racks together as needed, resulting in a large space occupied by the test tube racks. Alternatively, the test tube racks cannot be adjusted to carry different numbers of test tubes as needed, leading to waste and affecting the food testing experiments.

[0006] 2. Furthermore, the existing device has poor fixation of the test tubes, which makes the test tubes prone to shaking during transportation and movement, resulting in damage to the test tubes and reducing the protective effect on the test tubes. In addition, the existing test tube rack is inconvenient for collecting waste liquid and has poor sealing effect. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-5 This utility model provides a technical solution: a splicing multi-channel test tube rack for food testing, including a test tube rack 1, a base 2 at the bottom of the test tube rack 1, and a splicing mechanism on one side of the base 2;

[0036] The splicing mechanism includes a rectangular block 4, a slide rail 6, a slide groove 7, a slider 8, a slide bar 9, a first spring 10, and a locking block 11;

[0037] A rectangular block 4 is provided on one side of the base 2. The rectangular block 4 supports its internal structure. A slide rail 6 is installed on the inner side of the rectangular block 4. A slide groove 7 is opened on the outer side of the slide rail 6. A slider 8 is embedded in the inner cavity of the slide groove 7. There are two sliders 8, which are evenly and symmetrically distributed in the inner cavity of the slide groove 7. The sliders 8 can slide in the inner cavity of the slide groove 7. A slide bar 9 is installed on the outer side of the slider 8. The block 8 drives the slide bar 9 to slide. A first spring 10 is installed on the inner side of the slide bar 9. There are multiple first springs 10, which are evenly distributed on the inner side of the slide bar 9. A locking block 11 is installed on the outer side of the slide bar 9. The cross-section of the locking block 11 is an isosceles trapezoid. The slide bar 9 moves inward to compress the first spring 10. When the center position of the inner cavity of the insertion block 5 passes the locking block 11, the first spring 10 resets and locks the left and right test tube racks 1.

[0038] A plug-in mechanism is provided on the other side of the base 2;

[0039] The insertion mechanism includes an insertion block 5, a socket 13, and a slot 12;

[0040] On the other side of the base 2, there is a plug block 5. A socket 13 is opened on one side of the plug block 5. A slot 12 is opened at the center of the inner cavity of the plug block 5. The cross-section of the slot 12 is an isosceles trapezoid. At this time, the plug block 5 is in contact with the rectangular block 4 and continues to push the two test tube racks 1 inward. At this time, the inner cavity of the rectangular block 4 pushes the slide bar 9 inward through the plug block 5.

[0041] As a preferred embodiment, the multi-channel test tube rack further includes a removable clamping mechanism, which includes a clamp 14, an insert block 16, and a second spring 15.

[0042] A second spring 15 is fixedly connected to the inner side of the clamp 14 along the left and right direction. The clamp 14 is U-shaped. Insert blocks 16 are symmetrically arranged at the center of the top of the inner side of the clamp 14. The insert blocks 16 of the clamping mechanism are inserted into the slots 12 on the left and right sides of the plug block 5. The slot blocks 11 are pushed out of the slots 12, and the test tube rack 1 can be pulled out.

[0043] As a preferred option, the inner cavity of the test tube rack 1 is provided with an annular guide groove, which serves to guide the flow. A waste liquid collection hole is provided on one side of the annular guide groove, which serves to collect waste liquid.

[0044] As a preferred option, the test tube rack 1 is further provided with a slot module in its inner cavity. The slot module facilitates the entry of test tubes into the test tube rack 1. The slot module is equipped with a spring sealing ring inside, which protects the test tubes. During the transportation and movement of the test tube rack, the test tubes are not easily shaken, which will not cause damage to the test tubes and improves the protection effect of the test tubes. The bottom of the slot module is equipped with a leak-proof diaphragm, which prevents waste liquid from leaking out.

[0045] As a preferred option, the test tube rack 1 is further equipped with a rotating label ring 3 on the front side. The rotating label ring 3 facilitates the classification and storage of different test tubes, making them convenient for observation and use.

[0046] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0047] In use, the operator first moves the two test tube racks 1 towards each other. At this time, the insertion block 5 contacts the rectangular block 4. Continue to push the two test tube racks 1 inward. At this time, the inner cavity of the rectangular block 4 pushes the slide bar 9 inward through the insertion block 5. The slide bar 9 moves inward and compresses the first spring 10. When the center position of the inner cavity of the insertion block 5 passes the locking block 11, the first spring 10 returns to its original position and locks the two test tube racks 1, thus achieving the splicing of the two test tube racks 1. When disassembly is required, the insertion block 16 of the easy-to-disassemble clamping mechanism is inserted into the slots 12 on the left and right sides of the insertion block 5, and the locking block 11 is pushed out of the slots 12. At this time, the test tube rack 1 can be pulled out. This design has a simple structure, obvious benefits, and is worth promoting.
