Description

Technical Field

[0001] The utility model relates to the technical field of food safety detection, in particular to a food safety detection sample placing device. Background Art

[0002] Food safety testing is to detect harmful substances in food according to national indicators, mainly some harmful and toxic indicators, such as heavy metals, aflatoxin, etc. An important aspect of food science and engineering is to introduce and apply chemical unit operations, and develop food engineering unit operations, so as to promote the development of the food industry in the direction of large-scale, continuous and automated. The content of food inspection is very rich, including food nutritional component analysis, food pollutant analysis, food auxiliary materials and food additives analysis, food sensory identification, etc. Because the material of food samples is relatively easy to extract, especially liquid food, such as egg liquid, etc., the sample is often directly placed in a test tube through a burette for testing.

[0003] In order to ensure the freshness of food samples, the food needs to be stored in a low temperature environment. Usually, test tubes are placed in a storage box and ice is placed in the storage box. However, the existing storage box has poor sealing performance, which makes the ice melt quickly. Ice needs to be added to the storage box regularly, which greatly increases the labor intensity. In addition, since the storage box is in a low temperature environment, water droplets are easily condensed on the outer wall of the test tube. When the test tube is taken out, it is easy for the test tube to slide off, and the water droplets are easy to drip on the ground and cause pollution. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing placement box has poor sealing performance, which makes the ice melt faster and requires adding ice to the inside of the placement box regularly, which greatly increases the labor intensity. In addition, since the inside of the placement box is in a low temperature environment, water droplets are easily condensed on the outer wall of the test tube, and the test tube is easy to slide when the test tube is taken out, and the water droplets are easy to drip on the ground and cause pollution. A food safety testing sample placement device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a food safety testing sample placement device, comprising a placement box, a storage cavity is opened inside the placement box, a movable cover is movably installed at the rear end of the placement box, a drain pipe is fixedly connected to the surface of the placement box, baffles are movably installed on both sides of the outer wall of the placement box, fixed blocks are fixedly connected on both sides of the inner wall of the storage cavity, a fixed seat is fixedly installed on the top of the placement box, a placement groove is opened on the top of the fixed seat, a placement rack is fixedly connected to the bottom of the fixed seat, two mounting racks are fixedly connected to the inner wall of the placement rack, and a first scraper and a second scraper are respectively provided on the inner sides of the placement rack.

[0006] Preferably, the inner wall of the storage box is provided with heat-insulating cotton, one side of the baffle is located inside the storage cavity, one end of the drain pipe is located inside the storage cavity, and the other end of the drain pipe is provided with a baffle.

[0007] Preferably, a slide cylinder 1 is movably mounted on one side of the baffle, a connecting shaft is fixedly mounted on the surface of the baffle, and the connecting shaft is movably mounted on the inner wall of the placement box.

[0008] Preferably, a slide cylinder 2 is movably mounted on the bottom end of the fixed block, a guide rod is movably mounted inside the slide cylinder 2, the bottom end of the guide rod is movably mounted inside the slide cylinder 1, and a spring is provided on the surface of the guide rod.

[0009] Preferably, the top of the placement rack is communicated with the bottom of the placement groove, the surface of the placement rack is provided with air holes, and the bottom of the placement rack is provided with water leakage holes.

[0010] Preferably, a groove is provided on one side of the mounting frame, and a torsion spring is fixedly installed on the inner wall of the groove of the mounting frame.

The bottom end of the storage rack is located inside the storage cavity. Test tubes containing food samples are placed in the storage rack for storage. The ice cubes inside the storage cavity can keep the test tubes in a low-temperature state to ensure the freshness of the food samples. The spring installed on the surface of the guide rod can reset the baffle when it rotates, thereby improving the sealing of the storage box. The heat-insulating cotton arranged inside the storage box can improve the heat-insulating effect inside the storage cavity and reduce the temperature loss rate.

[0025] In this embodiment, the test tube containing the food sample is placed in the placement rack 3 through the placement groove 201, the bottom end of the placement rack 3 is located in the storage chamber 101, the movable cover 11 is closed to store the test tube, the baffle 13 is pushed inward to rotate around the connecting shaft 132, and then ice cubes are added to the storage chamber 101. When the baffle 13 rotates inward, the slide 131 moves upward to squeeze the spring 61 on the surface of the guide rod 6, and the baffle 13 is released. The spring 61 resets the baffle 13 to make the storage chamber 101 in a closed state. The thermal insulation cotton 15 arranged in the placement box 1 can improve the thermal insulation effect inside the storage chamber 101 and prevent the ice cubes from melting too quickly.

[0026] Example 2

[0027] like Figure 1-Figure 5 As shown, the top of the placement rack 3 is connected to the bottom of the placement groove 201, the surface of the placement rack 3 is provided with an air vent 301, the bottom of the placement rack 3 is provided with a water leakage hole 302, one side of the mounting rack 31 is provided with a groove, the inner wall of the groove of the mounting rack 31 is fixedly installed with a torsion spring 32, the first scraper 4 and the second scraper 5 have the same structure, one side of the outer wall of the first scraper 4 is fixedly connected with a connecting block 41, the interior of the connecting block 41 is fixedly installed with a fixed shaft 42, both ends of the fixed shaft 42 are movably connected to the inner wall of the groove of the mounting rack 31, and the fixed shaft 42 is located on the inner side of the torsion spring 32.

[0028] In this embodiment, when the test tube is placed in the placement rack 3, the test tube moves downward by the first scraper 4 and the second scraper 5 to squeeze it so that it is in an inclined state. The first scraper 4 twists the torsion spring 32 when rotating. At this time, the first scraper 4 and the second scraper 5 are in contact with the outer wall of the test tube, and the cold air in the storage chamber 101 contacts the outer wall of the test tube through the air vent 301.
