Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of food microbial testing sampling boxes, specifically to a foldable food microbial testing sampling box. Background Technology
[0002] Food microorganisms are closely related to humans, and research on food microorganisms requires sample collection. Sampling must be carried out on-site. After refrigeration, samples must be immediately transferred to a 0-4℃ environment for storage to ensure that bacteria do not multiply or die during the time from sampling to laboratory testing, so that the test results are closer to the actual situation.
[0003] A search revealed existing technology (publication number: CN220643131U), which describes "a food microbial testing sampling box, including an insulated box body. Several rotating heads are rotatably connected to both sides of the top of the insulated box body. A test tube storage sleeve is fixedly connected to the center of the bottom of each of the rotating heads. A through hole is opened at the center of each rotating head, communicating with the interior of the test tube storage sleeve. The bottom of the test tube storage sleeve is rotatably connected to the bottom surface of the inner wall of the insulated box body. Several telescopic rods are fixedly connected to both sides of the bottom of the inner wall of the insulated box body." The advantage of this invention is that when the rotating heads rotate, causing the test tube storage sleeve to rotate, a spiral guide groove can cause a push plate to slide upwards, pushing out a portion of the test tube inside the storage sleeve. This allows the outer wall of the test tube to be grasped and pulled outwards without opening the test tube stopper. Furthermore, the test tube can be completely inserted deep into the test tube storage sleeve, improving the refrigeration and insulation effect.
[0004] While existing food microbiology testing sampling boxes achieve refrigeration and insulation, as well as easy removal of test tube stoppers, they still have some shortcomings: Firstly, existing boxes typically only have a single compartment for holding test tubes, resulting in a limited storage capacity. When testing multiple foods for microbiology, multiple compartments are required, which is cumbersome. Secondly, when removing test tubes for testing, opening the lid exposes all tubes at once, making untested tubes susceptible to contamination during individual testing. This necessitates repeatedly opening and closing the lid to seal untested tubes, which is inconvenient. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, a foldable food microbial testing sampling box is provided to solve the problems mentioned in the background technology.
[0006] To achieve the above objectives, a foldable food microbial testing sampling box is provided, comprising: a box body and a box lid, wherein the box body and the box lid are hinged, and a flat buckle is provided on the outer wall of the corresponding side of the box body and the box lid; both the box body and the box lid have a placement slot and an ice tank inside; a limiting slot is provided at the upper end of the placement slot, and a guide sleeve is provided on the lower side of the placement slot; a rectangular sealing plug is provided at the upper end of the ice tank; a test tube is inserted inside the guide sleeve, and a cylindrical sealing plug is provided on the upper side of the test tube; a heat-conducting plate is provided on the outer wall of the guide sleeve, and a heat-conducting wall is connected in the middle of the heat-conducting plate, and the heat-conducting wall is the side wall of the ice tank.
[0007] Furthermore, both the box body and the box cover have internal cavities, and the guide sleeve is fixed in the internal cavity.
[0008] Furthermore, the placement groove is connected to the limiting groove, and both the placement groove and the limiting groove are designed as open slots.
[0009] Furthermore, an L-shaped pressure block is connected to the outer wall of the upper opening of the test tube, and the pressure block is correspondingly inserted into the limiting groove.
[0010] Furthermore, the rectangular sealing plug is designed as a T-shaped structure, and the protruding outer edge of the rectangular sealing plug is engaged in an open slot opened at the upper end of the ice tank.
[0011] Furthermore, the upper end of the cylindrical sealing plug is provided with a limiting block, and the upper end of the limiting block is provided with a handle, and the limiting block is in contact with the upper end of the test tube.
[0012] Furthermore, the heat-conducting plates are symmetrically connected to both sides of the heat-conducting wall, and the heat-conducting plates are placed in the inner cavity. The heat-conducting plates have through holes inside, and the guide sleeve is inserted into the through holes.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. When using the box for food microbial sampling, first open the flat snap to open the lid, allowing the top of the lid to flip onto a table or platform flush with the box. Then, pull the cylindrical sealing plug using the handle. At this time, the test tube will be lifted along with the plug by friction. Then, stabilize the pressure block with your other hand and pull the cylindrical sealing plug off to obtain the empty test tube. After the sample is collected, replace the cylindrical sealing plug and insert it into the guide sleeve through the placement slot. The guide sleeve and test tubes inside both the box and the lid allow the same sampling box to hold multiple test tubes, which is more convenient to use. Place the ice pack inside the ice tank and seal it with the rectangular sealing plug. The heat-conducting wall and heat-conducting plate cool the heat-conducting sleeve, and the heat-conducting sleeve conducts heat to cool the test tube.
[0015] 2. By using a cylindrical sealing plug, when opening the chamber for testing, the test tube can be pulled out as a whole through the cylindrical sealing plug. Then, in the same way as removing an empty test tube, the cylindrical sealing plug can be removed to take out the food sample in the test tube. This allows the test tubes to be opened gradually during testing, avoiding contamination of the remaining untested test tubes. Attached Figure Description

[0022] Reference Figures 1 to 5 As shown, this utility model provides a foldable food microbial testing sampling box, including: a box body 1 and a box cover 2, the box body 1 and the box cover 2 are hinged, and the outer wall of the corresponding side of the box body 1 and the box cover 2 is provided with a flat buckle. The box body 1 and the box cover 2 are both provided with a placement groove 11 and an ice tank 12. The upper port of the placement groove 11 is provided with a limiting groove 111, and the lower side of the placement groove 11 is provided with a guide sleeve 14. Meanwhile, the upper end of the ice tank 12 is provided with a rectangular sealing plug 121. A test tube 3 is inserted inside the guide sleeve 14, and a cylindrical sealing plug 32 is provided on the upper side of the test tube 3. A heat-conducting plate 123 is provided on the outer wall of the guide sleeve 14. A heat-conducting wall 122 is connected in the middle of the heat-conducting plate 123, and the heat-conducting wall 122 is set as the two side walls of the ice tank 12.
[0023] In this embodiment, the box body 1 and the box cover 2 constitute the main structure of the foldable food microbial detection sampling box involved in this application. By folding and opening the box body 1 and the box cover 2, the sampling capacity of the test tube 3 can be diversified and expanded.
[0024] Specifically, the placement slots 11 are arranged in a matrix, and the test tubes 3, cylindrical sealing plugs 32, and rectangular sealing plugs 121 do not affect the folding and closing of the lid 2 and the box body 1 after installation.
[0025] Specifically, the guide sleeve 14 includes an outer metal material and an inner thermally conductive silicone material to cool the outer wall of the test tube 3.
[0026] Specifically, both the cylindrical sealing plug 32 and the rectangular sealing plug 121 are made of rubber, and the lower end of the sealing plug has an arc-shaped chamfer.
[0027] like Figures 2 to 4 In the middle, both the box body 1 and the box cover 2 have an inner cavity 13, and the guide sleeve 14 is fixed in the inner cavity 13. The placement groove 11 is connected to the limiting groove 111, and both the placement groove 111 and the limiting groove 111 are open grooves. The outer wall of the upper tube opening of the test tube 3 is connected to an L-shaped pressure block 31, and the pressure block 31 is inserted into the limiting groove 111. The rectangular sealing plug 121 is a T-shaped structure, and the protruding outer edge of the rectangular sealing plug 121 is engaged with the inner cavity. In the open slot at the upper end of the ice tank 12, the upper end of the cylindrical sealing plug 32 is provided with a limiting block 33, and the upper end of the limiting block 33 is provided with a handle 34. The limiting block 33 is in contact with the upper end of the test tube 3. The heat-conducting plate 123 is symmetrically connected to both sides of the heat-conducting wall 122, and the heat-conducting plate 123 is placed in the inner cavity 13. The heat-conducting plate 123 has a through hole 124 inside, and the guide sleeve 14 is inserted into the through hole 124.
[0028] Specifically, the pressure block 31 and the test tube 3 are made of quartz glass as a whole, and after the pressure block 31 is engaged with the limiting groove 111, the upper end is flush with the limiting groove 111.
[0029] Specifically, both the heat-conducting wall 122 and the heat-conducting plate 123 are made of heat-conducting material, and the heat-conducting plate 123 fixes the guide sleeve 14.
[0030] When using this device for food microbiological sampling, first open the flat latch to open the lid, allowing the top of the lid to flip onto a table or platform flush with the device. Then, pull the cylindrical sealing plug using the handle. The friction will lift the test tube along with the plug. Stabilize the pressure block with your other hand, and then forcefully pull off the cylindrical sealing plug to obtain the empty test tube. After sample collection, replace the cylindrical sealing plug and insert the tube downwards into the guide sleeve through the placement slot. The guide sleeves and test tubes inside both the device and the lid allow the same sampling box to hold multiple tubes. The previous method, which involved using individual test tubes and was therefore cumbersome, utilizes an ice tank to place ice packs inside, which are then sealed with rectangular plugs. Cooling of the test tubes is achieved through heat-conducting walls and plates, and the heat-conducting sleeve also cools the test tubes through conduction. The use of cylindrical plugs allows for easy removal of the entire test tube when opening the chamber for testing. The plug is first pulled out along with the test tube, and then, similar to removing an empty test tube, the plug is removed to retrieve the food sample. This allows for the gradual opening of test tubes during testing, preventing contamination of untested tubes.
[0031] This invention achieves the effect of expanding the capacity of a single sampling box to include multiple sampling tubes, based on existing foldable food microbial testing sampling box technology, and ensures that samples remain uncontaminated during sequential testing, making the overall operation more convenient.
