Description

Technical Field

[0001] This utility model relates to the field of livestock product testing technology, and in particular to a sample rack for livestock product safety testing. Background Technology

[0002] Animal product safety testing is a crucial step in ensuring food safety, involving the assessment of the quality, hygiene, and safety of animal-derived products such as meat, dairy products, and eggs. With increasing consumer concern about food safety and stricter regulatory requirements, the efficiency and accuracy of animal product testing have become critical needs. As a fundamental tool in the testing process, the core function of a sample rack is to provide stable support for sample tubes, preventing samples from moving or tipping over during testing.

[0003] Traditional fixed sample racks (such as metal test tube racks and plastic sampling bottle racks) must be fixed on the workbench, refrigerator or shelf, whether or not they are in use. When adding samples or centrifuging, the testing personnel need to frequently move the racks to make room. In addition, crowded workbench may also lead to disordered placement of equipment (such as insufficient spacing between pipettes and centrifuges), increasing the risk of cross-contamination of samples. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing sample rack adopts a fixed structure, which occupies a large space and causes the operating space to be squeezed during use, resulting in a decrease in efficiency. Therefore, a sample rack for the safety testing of livestock products is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: a sample rack for safety testing of livestock products, comprising a base, the internal space of which is divided into a storage cavity and a bottom cavity by a filter screen, wherein two support plates are rotatably connected in the storage cavity by a connecting shaft, and a perforated plate assembly is detachably installed between the two support plates, wherein when the support plates are folded inside the storage cavity, the top of the perforated plate assembly forms a plane with the top of the base.

[0006] As a further description of the above technical solution: the orifice plate assembly includes a fixing plate that is detachably connected to the base, and the fixing plate has a plurality of insertion holes arranged in an array for inserting sampling tubes.

[0007] As a further description of the above technical solution: the two ends of the fixing plate are provided with limiting ends through the opening of the mounting groove, a return spring is provided between the limiting end and the inner wall of the mounting groove, and a handle extending to the outside of the fixing plate is provided on the limiting end.

[0008] The support plate has several pairs of positioning holes along its height direction that cooperate with the limiting end.

[0009] As a further description of the above technical solution: the base has a connecting hole on the inner wall of the storage cavity that mates with the limiting end.

[0010] As a further description of the above technical solution: a gasket is provided on the inner wall of the socket, and the gasket is made of either silicone rubber or polyurethane foam.

[0011] As a further description of the above technical solution: a pair of handles are provided on the base.

[0012] As a further description of the above technical solution: a water collection tray is detachably connected to the bottom cavity, and a handle is provided on the water collection tray.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] By using a foldable sample rack, the rack can be unfolded during testing, transforming from a flat state into a double-layer test tube rack structure to precisely match the current sample volume. During breaks or after operation, the rack can be folded into a flat state and directly stored in the workbench drawer or side wall shelf, freeing up workbench space. This reduces workbench congestion and lowers the risk of cross-contamination when conducting livestock product testing. Attached Figure Description

[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. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 This embodiment provides a sample rack for livestock product safety testing, including a base 1, whose internal space is divided into a storage cavity 3 and a bottom cavity 4 by a filter screen 2. Two support plates 5 are rotatably connected in the storage cavity 3 by a connecting shaft. A perforated plate assembly 6 is detachably installed between the two support plates 5. When the support plates 5 are folded inside the storage cavity 3, the top of the perforated plate assembly 6 forms a plane with the top of the base 1.

[0024] In this invention, the support plate 5 is hinged to the base 1 via a connecting shaft and can be unfolded to a vertical state or folded to a horizontal state. When it is necessary to place the sample tubes during the testing process, the orifice plate assembly 6 is first removed from the base 1, and then the two support plates 5 are unfolded from the storage cavity 3 so that the two support plates 5 are in a vertically parallel state. Then, the orifice plate assembly 6 is snapped between the two support plates 5 to form a sample rack, which realizes the placement of sample tubes. After the test is completed, the orifice plate assembly 6 is removed, and then the two support plates 5 are folded to a horizontal state. The orifice plate assembly 6 is then placed in the storage cavity 3, saving the space occupied by the sample rack.

[0025] Specifically, such as Figures 1-4 As shown, the orifice plate assembly 6 includes a fixing plate 61 that is detachably connected to the base 1. The fixing plate 61 has a plurality of insertion holes 62 for inserting sampling tubes arranged in an array. The two ends of the fixing plate 61 are provided with limiting ends 64 through the mounting grooves 63. A return spring 65 is provided between the limiting ends 64 and the inner wall of the mounting groove 63. The limiting ends 64 are provided with handles 66 extending to the outside of the fixing plate 61. The support plate 5 has a plurality of positioning holes 51 that cooperate with the limiting ends 64 along its height direction.

[0026] In the specific unfolding and storage of the sample rack, during the unfolding process, the support plate 5 is unfolded to a vertical state. The handles 66 at both ends of the fixing plate 61 are pulled towards the middle of the fixing plate 61, so that the fixing plate 61 drives the limiting end 64 to squeeze the return spring 65 and move towards the inside of the mounting groove 63. At this time, the end of the limiting end 64 away from the return spring 65 is flush with the two sides of the fixing plate 61. Maintain this state and place the fixing plate 61 between the two support plates 5. Locate the position of the positioning hole 51 on the support plate 5. Then slowly release the handles 66. The limiting end 64 pops outward under the elastic force of the return spring 65 and gets stuck in the positioning hole 51, so that the fixing plate 61 and the two support plates 5 are kept stable. Then, the test tube containing the livestock product test sample is passed through the insertion hole 62 of the fixing plate 61, so that the bottom of the test tube rests on the filter screen 2 and the test tube is placed.

[0027] After the test is completed, the limiting end 64 is retracted into the mounting groove 63 using the handle 66. At this time, the limiting end 64 disengages from the positioning hole 51 of the support plate 5. The support plate 5 rotates to a horizontal state under the action of the connecting shaft. The support plate 5 is then stored in the storage cavity 3 of the base 1. The fixing plate 61 is kept in the retracted state of the limiting end 64. The fixing plate 61 is placed in the storage cavity 3. At this time, the fixing plate 61 rests on the support plate 5. Since the base 1 has a connecting hole 11 on the inner wall of the storage cavity 3 that mates with the limiting end 64, when the handle 66 is released to release the limiting end 64, the limiting end 64 will be inserted into the connecting hole 11 of the base 1, thereby forming a flat structure for the sample rack, freeing up table space. This reduces table congestion and the risk of cross-contamination during livestock product testing. The base 1 is equipped with a pair of handles, which facilitate transport when the sample rack is folded.

[0028] Additionally, it should be noted that a gasket 67 is provided on the inner wall of the socket 62. The gasket 67 is made of either silicone rubber or polyurethane foam. The elastic material of the gasket 67 can absorb vibration or impact, preventing the sampling tube from being damaged by collision during insertion, fixing, or transportation.

[0029] Specifically, such as Figure 1 and Figure 5 As shown, a detachable water collection tray 7 is connected to the bottom cavity 4, and a handle is provided on the water collection tray 7. The water collection tray 7 is located below the bottom cavity 4 and can collect liquids that leak from the storage cavity 3 after being separated by the filter screen 2 (such as residual water during cleaning, sample overflow, etc.), preventing liquids from directly contacting the laboratory tabletop or equipment, and preventing contamination or corrosion. The water collection tray 7 is detachable from the bottom cavity 4, which facilitates regular disassembly and emptying or cleaning of the accumulated liquids, keeping the inside of the equipment clean.

[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.
