Description

Technical Field

[0001] The invention relates to the technical field of food detection, in particular to a sample storage device for bean product microorganism detection. Background Art

[0002] Soy products are processed foods made from beans such as soybeans, adzuki beans, green beans, peas, and broad beans. Most soy products are tofu and its products made from coagulated soybean milk. China is the home of soybeans, and China has a history of 5,000 years of soybean cultivation. Soy products are also included in the dietary taboos for gout patients. In ancient China, various beans were used to create tofu, tofu silk, fermented bean curd, soy milk, fermented black beans, soy sauce, bean sausage, and bean tendons. By processing soy milk into more complex soy products, different food flavors can be obtained, and the shelf life of food can also be extended to a certain extent. However, tofu-like soy products still have the problem of short shelf life and easy spoilage.

[0003] Food microbiological testing is a testing method that uses the theories and methods of microbiology to examine the types, quantity, properties of microorganisms in food and their impact on human health, in order to determine whether the food meets the quality standards. In order to obtain a unique flavor, soy products need to adopt a variety of different and very unique production methods. Fresh soy products have a short shelf life. In order to obtain a longer shelf life, soy products such as dried tofu and fermented black beans will choose to change the properties and taste of soy products by pickling and fermenting. Therefore, soy products generally need to be tested for microorganisms during and after production to ensure food safety.

[0004] When testing soy products, it is generally necessary to take samples from multiple locations on the sampled soy products, mix them thoroughly to obtain extracts or soy product materials, store them in test tubes, and finally conduct unified testing in the laboratory. The sample storage device is a device used to store sampling test tubes. It can generally store a large number of sampling test tubes, and also needs to have temperature control effects such as refrigeration. Existing storage devices with heat preservation effects generally have thicker inner walls for heat preservation, resulting in a smaller internal space.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 8 In an embodiment of the present invention, a sample storage device for detecting microorganisms of bean products comprises a box body 1 and a test tube 4; a support plate 3 is installed in the box body 1, and a plurality of primary through holes 31 are opened on the support plate 3, and the test tube 4 is placed in the primary through hole 31; a vertical support column 4 is installed in the middle of the box body 1, and a lifting structure 6 is installed inside the box body 1, and the lifting structure 6 comprises a mounting seat 62 symmetrically installed on both sides of the box body 1, and a plurality of row grooves 622 are opened on the mounting seat 62, and a plurality of support rows 61 are slidably installed in the row grooves 622, and the support rows 6 1 is provided with a row of primary grooves 611 corresponding to the primary through holes 31, and the test tube 4 is placed in the primary grooves 611; the side of the mounting seat 62 away from the support plate 3 is provided with through grooves 623 corresponding to the rows of grooves 622, and a V-shaped adjustment plate 65 is rotatably installed in the through groove 623, and one end of the adjustment plate 65 is against the end surface of the support row 61; the lifting structure 6 includes an adjustment rod 63 vertically passing through the support column 4, and a symmetrical support rod 64 is installed on the adjustment rod 63, and the end of the adjustment plate 65 away from the support row 61 is connected to the support rod 64; A buckle structure 7 is installed in the support column 4, and the buckle structure 7 is used to lock the height position of the adjustment rod 63; A fastening structure 5 is disposed in the box body 1 , and the fastening structure 5 is used to clamp the test tube 4 .

[0028] In the present device, a support plate 3 is placed in a box body 1, and a primary through hole 31 is opened on the support plate 3 for placing a test tube 4 to provide support for the test tube 4. A lifting structure 6 is also arranged inside the box body 1. The mounting seat 62 of the lifting structure 6 is fixed in position, and a support row 61 is placed inside the mounting seat 62 using a row groove 622. The width of the through groove 623 at the bottom is smaller than the width of the row groove 622, so that the support row 61 can be prevented from falling. The support row 61 can be raised and lowered, and a primary groove 611 is arranged on the support row 61. The bottom of the test tube 4 is inserted into the primary groove 611 to keep the test tube 4 vertical.

[0029] The adjustment plate 65 in the through slot 623 can rotate relative to its middle position, and one end of the adjustment plate 65 remains approximately horizontal and rests on the support row 61, while the other end is connected to the adjustment rod 63 located inside the support column 4 through the support rod 64. The device mainly adjusts the lifting structure 6 by controlling the adjustment rod 63. When a test tube 4 located in a row needs to be taken, the adjustment rod 63 corresponding to the row in the middle area is pressed. As the adjustment rod 63 is pressed down, the support rod 64 pushes the adjustment plate 65 to rotate. The adjustment plate 65 rotates outward and lifts the support row 61, so that the test tube 4 in the corresponding row can be lifted synchronously, which is convenient for the inspector to take.

[0030] The buckle structure 7 is used to clamp the adjusting rod 63 after the adjusting rod 63 is pressed down, so that the test tube 4 remains in the lifted state after the operator lets go, which is convenient for taking. After use, the corresponding adjusting rod 63 is released by the buckle structure 7, so that the support row 61 falls again. The fastening structure 5 is used to fasten the test tube 4 in this process, that is, the test tube 4 is basically not subject to resistance when inserted downward, but after the test tube 4 is inserted, the process of pulling it out upward will be subject to resistance, so as to avoid shaking and collision during transportation, or the test tube 4 falling due to the tilt of the box body 1 after the box body 1 is opened. In addition, after a certain adjusting rod 63 is pressed down, the fastening structure 5 of the corresponding row will lose the fastening effect, which will not affect the lifting of the test tube 4 and the operation of the operator taking the test tube 4.

[0031] As another embodiment of the present invention, please refer to Figures 2 to 5 The lifting structure 6 includes a cross bar 66, which connects one end of each adjustment plate 65 away from the support row 61, and the cross bar 66 is parallel to the bottom surface of the box body 1. A pressing rod 631 is installed on the adjustment rod 63, and the pressing rod 631 passes through the support plate 3. The width of the pressing rod 631 is greater than the width of the adjustment rod 63, and the support plate 3 is provided with a primary through slot 32 corresponding to the pressing rod 631. The cross bar 66 is used to connect multiple adjustment plates 65 located on the same side, so that the adjustment plates 65 can rotate synchronously, so that the support row 61 remains horizontal after being lifted. The pressing rod 631 increases the length of the adjustment rod 63 to facilitate the pressing operation. By making the pressing rod 631 have a width greater than the adjustment rod 63, it is convenient to use the step-like structure at the connection between the pressing rod 631 and the adjustment rod 63 to adjust the fastening structure 5.

[0032] See also Figure 2 , Figure 3 and Figure 6The buckle structure 7 includes a clamping plate 71 passing through the support column 4, and a plurality of secondary through grooves 711 are formed on the clamping plate 71. The adjusting rods 63 pass through the corresponding secondary through grooves 711 respectively, and wedge blocks 632 are fixedly installed on both sides of the adjusting rod 63, and wedge-shaped stoppers 712 are respectively provided on the inner walls on both sides of the secondary through grooves 711. The clamping plate 71 can only slide horizontally inside the support column 4, and the adjustment rod 63 passes through the secondary through slot 711. Under normal conditions, the height of the wedge block 632 is higher than the height of the clamping plate 71. When the adjustment rod 63 is pressed down, the wedge block 632 abuts against the stopper 712 and pushes the clamping plate 71 to move horizontally. After the wedge block 632 passes through the clamping plate 71, the clamping plate 71 is reset, and the stopper 712 clamps the wedge block 632 to prevent the adjustment rod 63 from resetting. After taking the test tube 4, the clamping plate 71 is controlled to slide again to release the constraint on the wedge block 632. The weight of the test tube 4 and the support row 61 presses the adjustment plate 65 downward, and finally drives the adjustment rod 63 to automatically rise and reset. In addition, an elastic member such as a spring can be used between the bottom of the adjustment rod 63 box 1 to support it, so as to ensure that the reset operation of the adjustment rod 63 can be carried out stably.

[0033] See also Figure 1 and Figure 6 , one end of the clamping plate 71 is connected to a pressing block 72, and the pressing block 72 passes through the side wall of the box body 1. The end of the clamping plate 71 close to the pressing block 72 is installed with a primary spring 73 opposite to the installation direction of the pressing block 72, and the primary spring 73 is connected to the support column 4. After taking the test tube 4, the pressing block 72 is squeezed inward from the outside to open the buckle structure 7, and the test tube 4 automatically falls down. The opening at the pressing block 72 is very small, which basically does not affect the internal insulation effect of the box body 1. In order to further improve the insulation effect, a flexible film material can also be used to cover the pressing block 72 to reduce the gas circulation inside and outside the box body 1. The primary spring 73 is used to achieve the effect of automatic resetting of the clamping plate 71.

[0034] See also Figure 2 , Figure 7 and Figure 8 The fastening structure 5 includes a positioning row 51 and a limiting frame 52. The limiting frame 52 is fixedly installed on both sides of the support column 4. The positioning row 51 is provided with a secondary through hole 511 corresponding to the position of the primary through hole 31. The positioning row 51 is slidably connected with the support column 4. The internal cross-section of the limiting frame 52 is a trapezoid. The limiting frame 52 is located between the support plate 3 and the positioning row 51. The limiting frame 52 is located above the positioning row 51, and the limiting frame 52 cooperates with the positioning row 51 to limit the test tube 4.

[0035] See also Figure 2 , Figure 7 and Figure 8Two opposite extrusion plates 53 are placed in the limit frame 52. The outer side of the extrusion plates 53 matches the trapezoidal inner side of the limit frame 52. The inner side of the extrusion plates 53 is provided with a secondary groove 531 that matches the shape of the secondary through hole 511. The thickness of the extrusion plates 53 is greater than the thickness of the limit frame 52. The extrusion plates 53 are located in the limit frame 52, and the positioning row 51 is pushed up, and the two extrusion plates 53 are pressed tightly in the limit frame 52. When the test tube 4 is inserted downward, the resistance generated causes the positioning row 51 to move downward, and the extrusion plates 53 fall downward, and the spacing becomes larger, so that the test tube 4 can be inserted normally. After the position of the test tube 4 is fixed, due to the lack of downward thrust, the positioning row 51 moves up again, and the test tube 4 is pressed again by the extrusion plates 53. After this, if the test tube 4 is subjected to an upward external force, the extrusion plates 53 continue to move upward under the resistance, and will only be pressed tighter and tighter in the limit frame 52 to ensure that the test tube 4 will not slide.

[0036] See also Figure 2 , Figure 7 and Figure 8 , a three-level through slot 512 corresponding to the cross section of the adjusting rod 63 is opened in the middle of the positioning row 51, and a three-level groove 532 corresponding to the cross section of the pressing rod 631 is opened in the middle of the squeezing plate 53. When the adjusting rod 63 corresponding to a row is pressed, since the three-level through slot 512 on the positioning row 51 matches the cross section of the adjusting rod 63, which is smaller than the cross section of the pressing rod 631, the downward movement of the pressing rod 631 will cause the positioning row 51 to passively move downward, and the squeezing plate 53 will fall and unfold, then the test tube 4 will lose its fastening force and can be taken out directly. Through this structure, the fixing effect of the test tube 4 can be significantly enhanced, and the fastening effect will not conflict with the lifting function when the lifting structure 6 lifts the test tube 4, avoiding the shaking or falling of the test tube 4 caused by the shaking or tipping of the box body 1 during transportation, resulting in the occurrence of breakage.

[0037] See also Figure 2 , Figure 7 and Figure 8 , the two ends of the positioning row 51 are respectively installed with an insertion rod 54, the mounting seat 62 is provided with a concave hole 621 corresponding to the insertion rod 54, the insertion rod 54 is inserted into the concave hole 621, and the insertion rod 54 is sleeved with a secondary spring 55. The insertion rod 54 is inserted into the concave hole 621 on the positioning seat, and the positioning of the positioning row 51 can be enhanced by the insertion rod 54. The secondary spring 55 provides support for the positioning row 51. Under the premise of no external force, the positioning row 51 can naturally press the extrusion plate 53 into the limit frame 52.

[0038] See also Figures 1 to 3, an exhaust port 11 is provided on one side of the box 1, a plurality of semiconductor refrigerators 12 are installed inside the exhaust port 11, and a battery 13 is installed inside the box 1. The semiconductor refrigerator 12 is used to provide refrigeration and heat preservation effects inside the box 1, and fans for enhancing airflow are provided on both sides of the semiconductor refrigerator 12, the exhaust port 11 is used to discharge hot air, and the battery 13 supplies energy for the device. In order to improve the refrigeration and heat preservation effects, a temperature sensor should also be provided in the box 1. Since this structure is a common sense structure, it is not described restrictively.

[0039] See also Figure 1 and Figure 3 The box body 1 is provided with a cover plate 2, a lock 22 is connected between the cover plate 2 and the box body 1, a handle 23 is provided on the cover plate 2, a buffer pad 21 is provided inside the cover plate 2, and a four-level groove 211 is provided in the middle of the buffer pad 21. The lock 22 is used to fix the cover plate 2, and the handle 23 can be installed on the cover plate 2 or on both sides of the box body 1, so that the operator can carry the device and move it. The buffer pad 21 is pressed on the surface of the test tube 4 after the cover plate 2 is closed, so as to further prevent the test tube 4 from shaking. The four-level groove 211 corresponds to the position of the pressing rod 631.

[0040] The working principle of the present invention is: The device is provided with a semiconductor refrigerator 12 inside the box body 1 for heat preservation and refrigeration. A support plate 3 with a primary through hole 31 is installed near the surface of the box body 1. A lifting structure 6 is provided inside the box body 1.
