Abstract
Description
Technical Field
[0001] This utility model relates to the field of food inspection and sampling technology, specifically a food inspection sampling box assembly. Background Technology
[0002] Food testing sampling kits are a standardized set of tools used in the food sampling process to ensure the standardization of sampling, the safety and integrity of samples. Their design aims to ensure that samples remain uncontaminated and stable throughout the entire process from sampling to laboratory testing, thereby guaranteeing the accuracy and reliability of test results.
[0003] A search revealed a Chinese patent document that discloses a food testing sampling box device (publication number: CN208393974U). Although the device includes a sorting box, a sponge layer, a spring, a fixing groove, a test tube placement box, a pull head, a sealing cap, a plug, and a sampling tube, the sorting box is located inside the left side of the sampling box body, the sponge layer is laid on the inner wall of the sorting box, the spring is located on the upper end face of the fixing groove, and the fixing groove is located inside the lower side of the sorting box.
[0004] The existing testing and sampling boxes of the aforementioned equipment have significant shortcomings: they do not achieve "one box for two purposes," food samples and tools are often mixed together in a disorderly manner, which can easily lead to contamination. When sampling in the market, due to the large quantity of food, there is often insufficient space in the box, which means that some samples cannot be refrigerated, which may cause food spoilage, affect the accuracy of testing, and even require repeated sampling due to sample failure, increasing workload and cost. At the same time, there is a risk of cross-contamination, which is not conducive to the implementation of sampling procedures and the assurance of the reliability of test results. Utility Model Content
[0005] The purpose of this invention is to provide a food testing sampling box assembly to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a food inspection sampling box assembly, including a box body, a top cover rotatably connected to the top of the box body, a handle fixedly connected to one side of the top cover, a splicing assembly movably connected to the bottom of the box body, an extension box fixedly connected to the bottom of the splicing assembly, a baffle fixedly connected to the middle of the inner cavity of the box body, a first cavity and a second cavity opening in the inner cavity of the box body, with the baffle located between the first and second cavity openings, and a placement structure rotatably connected to the inner cavity of the second cavity opening. This design allows for flexible combination of the box body and the extension box through the splicing assembly, solving the problem of insufficient capacity when there are too many samples. The inner cavity of the box body is clearly divided, the first and second cavity openings, together with the baffle, provide efficient classification, and the rotatable placement structure of the second cavity opening improves space utilization and ease of retrieval. The top cover and handle design enhances portability, and the overall design balances expansion needs with operational practicality, making it suitable for large-scale sampling scenarios in the food market.
[0007] Preferably, the two sides of the box are movably connected with diagonal straps, and the four corners of the bottom of the box have first insertion ports. A refrigerated drawer is slidably connected to one side of the box, and a test tube drawer is slidably connected to one side of the extension box. Second insertion ports are provided on all four sides of the extension box. The refrigerated drawer is made of insulating material to ensure sample freshness, while the test tube drawer facilitates the categorized storage of small samples. The box and extension box are securely connected via insertion ports and buckles, balancing capacity expansion and structural stability. The combination of partitioned storage and temperature control functions meets the needs of storing multiple samples while ensuring the quality of tested samples, making it highly practical.
[0008] Preferably, the splicing assembly has two connecting posts, with a threaded rod threaded between them. Each end of the two connecting posts is rotatably connected to a first adjusting rod. A recoil spring is fixedly connected to the surface of each first adjusting rod. A fixing plate is fixedly connected to one end of each first adjusting rod. A right-angle post and two fixing stakes are fixedly connected to the top and bottom ends of the fixing plate, respectively, with the two fixing stakes located on either side of the right-angle post. The splicing assembly is ingeniously designed; the connecting posts and threaded rods work together to adjust the spacing, adapting to different splicing requirements. The first adjusting rod, combined with the recoil spring, can flexibly buffer external forces and protect the internal sample.
[0009] Preferably, one side of each of the fixed posts is fixedly connected to an insertion post, and one end of the insertion post is respectively inserted into the first socket and the second socket. One side of each of the two first adjusting rods is fixedly connected to a recovery spring. One end of each of the two connecting posts is rotatably connected to a second adjusting rod, and one end of each of the two second adjusting rods rotates intersectingly. The insertion post is inserted into the first socket and the second socket, which strengthens the connection stability between the box and the extension box and prevents the splicing from loosening. The recovery spring provides elastic buffer for the first adjusting rod and reduces the impact of vibration on the sample during transportation.
[0010] Preferably, two rotating fans are fixedly connected to the bottom of the first cavity, and a second placement rack is fixedly connected to the four sides of the inner wall of the first cavity. A first placement rack is movably connected to the top of the second placement rack. Several food tubes are fitted and connected to the inner cavity of the first placement rack. Since the first cavity is to hold food tubes, the inner wall of the first cavity is made of heat-insulating material, which can flexibly adjust the opening and closing of the internal space to facilitate the placement and removal of food tubes. The double-layer placement rack improves space utilization, meets the storage of samples of various specifications, and the heat-insulating material inner wall can maintain a constant temperature at the cavity, avoiding temperature changes from affecting the quality of food samples.
[0011] Preferably, the placement structure includes a first shelf, with fourth rotating rods rotatably connected to both sides of one end of the first shelf, and one end of each of the two fourth rotating rods rotatably connected to both sides of the inner wall of the second cavity. Third rotating rods are rotatably connected to both sides of the other end of the first shelf. A second shelf is rotatably connected between the two third rotating rods, with first rotating rods rotatably connected to both sides of the second shelf, and one end of each of the two first rotating rods rotatably connected to both sides of the inner wall of the second cavity. A second rotating rod is rotatably connected to one side of each of the two third rotating rods. One side of each of the two second rotating rods is rotatably connected to both sides of the inner cavity of the top cover. The placement structure achieves coordinated action between the first and second shelves and the top cover through the linkage of multiple sets of rotating rods: when the top cover is opened, the rotating rods drive the shelves to unfold automatically, increasing the usable space of the second cavity opening; when the top cover is closed, the shelves fold and store with the rotating rods, saving space. Compared with the prior art, the beneficial effects of this utility model are: the interior of the box is divided into two, one side holds the food to be inspected, and the other side holds tools through the first and second shelves; the first cavity opening is made of heat-insulating material, and the bottom rotating fan helps the cold air flow of the refrigerated drawer to ensure heat preservation. For a large amount of food, the splicing component can rotate the threaded rod to fix the fixed plate structure to the box body, achieving flexible expansion and adapting to the large sampling needs of the market.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0019] Please see Figure 1-5 This utility model provides a food inspection sampling box assembly, including a box body 4, a top cover 2 rotatably connected to the top of the box body 4, a handle 1 fixedly connected to one side of the top cover 2, a splicing assembly 6 movably connected to the bottom of the box body 4, an extension box 5 fixedly connected to the bottom of the splicing assembly 6, a baffle 31 fixedly connected to the middle of the inner cavity of the box body 4, a first cavity 32 and a second cavity 33 opened in the inner cavity of the box body 4, and the baffle 31 is located between the first cavity 32 and the second cavity 33. A placement structure 8 is rotatably connected to the inner cavity of the second cavity 33. When there are many food items to be inspected in the market and the box body 4 cannot hold them all, the extension box 5 can be spliced together with the whole by adjusting the splicing assembly 6. The whole can be opened by lifting the handle 1, and the tool rack can be placed on the placement structure 8 to prevent the inside from being cluttered and contaminated.
[0020] In this embodiment of the application, the following features are used: a diagonal strap 3 is movably connected to both sides of the box body 4; a first insertion port 7 is provided at the four corners of the bottom of the box body 4; a refrigerator drawer 27 is slidably connected to one side of the box body 4; a test tube drawer 9 is slidably connected to one side of the extension box 5; and a second insertion port 10 is provided around the extension box 5, allowing the diagonal strap 3 to be draped over the user for movement. In addition, the first insertion port 7 at the bottom of the box body 4 facilitates splicing with the splicing component 6. Furthermore, there are second insertion ports 10 at the top and bottom of the extension box 5, facilitating the subsequent accumulation and fixation of other extension boxes 5.
[0021] In this embodiment, the splicing component 6 has two connecting posts 16, with a threaded rod 15 threaded between them. Both ends of the two connecting posts 16 are rotatably connected to first adjusting rods 13. Each surface of the first adjusting rod 13 is fixedly connected to a reclining spring 17. One end of each first adjusting rod 13 is fixedly connected to a fixing plate 14. The top and bottom ends of the fixing plate 14 are respectively fixedly connected to a right-angle post 11 and two fixing stakes 12, with the two fixing stakes 12 located on both sides of the right-angle post 11. One side of each fixing stake 12 is fixedly connected to an insertion post 29, with one end of the insertion post 29 inserted into a first insertion port 7 and a second insertion port 10. One side of each of the two first adjusting rods 13 is fixedly connected to a reclining spring 17. One end of each of the two connecting posts 16 is rotatably connected to a second adjusting rod 18. One end of the assembly is rotated to place the splicing component 6 on top of the extension box 5, and then the box body 4 is placed on top. At this time, the whole assembly is supported and unfolded by two second adjusting rods 18. The operator takes out a power tool and puts it on one end of the threaded rod 15. After putting it on, it is rotated. Because the middle of the two fixing plates 14 is a threaded hole, the second adjusting rods 18 on both sides will be adjusted when rotating. At the same time, several first adjusting rods 13 will adjust the angle between the first adjusting rods 13 and the two ends of the fixing plate 14 according to the rotation of the threaded rod 15, so that one side of the right-angle post 11 on the upper and lower sides of the fixing plate 14 contacts the corner of the box body 4 and the extension box 5. When rotating, according to the adjustment, several insertion posts 29 will be inserted into the first insertion port 7 and the second insertion port 10 to ensure that the box body 4 and the extension box 5 do not fall off during operation, thus completing the splicing work.
[0022] In this embodiment of the application, two rotating fans 28 are fixedly connected to the bottom of the first cavity 32. A second placement rack 30 is fixedly connected to the four sides of the inner wall of the first cavity 32. A first placement rack 20 is movably connected to the top of the second placement rack 30. Several food tubes 19 are sleeved and connected to the inner cavity of the first placement rack 20, so that the ice can be placed inside the two refrigerator drawers 27. Since the rotating fans 28 are fixed on the first cavity 32, one end of the rotating fans 28 is aligned with the top of the refrigerator drawers 27. When the rotating fans 28 rotate, they will transfer the cold air drawn from the refrigerator drawers 27 through the other end to ensure the refrigeration effect of the food and prevent the food from spoiling due to weather. In addition, the first placement rack 20 is detachable, and the bottom end of the first placement rack 20 is placed on the second placement rack 30.
[0023] In use, the placement structure 8 includes a first shelf 21. Both sides of one end of the first shelf 21 are rotatably connected to fourth rotating rods 26, and one end of each of the two fourth rotating rods 26 is rotatably connected to both sides of the inner wall of the second cavity 33. Both sides of the other end of the first shelf 21 are rotatably connected to third rotating rods 25. A second shelf 22 is rotatably connected between the two third rotating rods 25. Both sides of the second shelf 22 are rotatably connected to first rotating rods 23, and one end of each of the two first rotating rods 23 is rotatably connected to both sides of the inner wall of the second cavity 33. On one side, two third rotating rods 25 are rotatably connected to a second rotating rod 24, and one side of the two second rotating rods 24 is rotatably connected to both sides of the inner cavity of the top cover 2. Tweezers, cotton swabs, and gloves are placed on the first shelf 21 and the second shelf 22. When the top cover 2 is opened, the second rotating rod 24 will adjust to the inner wall of the top cover 2, so that the first shelf 21 and the second shelf 22 will unfold out of the inner cavity of the second cavity 33 under the rotation of the third rotating rod 25, the first rotating rod 23 and the fourth rotating rod 26.
[0024] In this embodiment of the application, before use, personnel should prepare by placing the sterilized food tube 19, tweezers, cotton swabs, gloves, etc., inside the box 4. After preparation, personnel should open the top cover 2 using the handle 1. The second rotating rod 24 will adjust according to the inner wall of the top cover 2, so that the first shelf 21 and the second shelf 22 are opened from the inner cavity of the second cavity 33 by the rotation of the third rotating rod 25, the first rotating rod 23, and the fourth rotating rod 26. Unfold the container and place the tweezers, cotton swabs, gloves, etc., inside the first shelf 21 and the second shelf 22. Then, place the first shelf 20 onto the second shelf 30 on the inner wall of the first cavity 32. After placement, place the food tubes 19 in the slots inside the first shelf 20 in sequence. When there are many market foods to be sampled, the box body 4 and the extension box 5 need to be assembled in advance to prevent the food samples from not being collected in a unified manner. Place the assembly 6 on top of the extension box 5. After placing the box 4 on top, the entire structure is supported and unfolded by two second adjusting rods 18. The operator takes out a power tool and fits it onto one end of the threaded rod 15. After fitting it, the tool is rotated. Because the middle of the two fixing plates 14 has a threaded hole, the second adjusting rods 18 on both sides will adjust during rotation. At the same time, several first adjusting rods 13 will adjust the angle between the first adjusting rods 13 and the two ends of the fixing plate 14 according to the rotation of the threaded rod 15. This makes one side of the right-angle post 11 on the upper and lower sides of the fixing plate 14 contact the corner of the box 4 and the extension box 5. During rotation, several insertion posts 29 will be inserted into the first insertion port 7 and the second insertion port 10 to ensure that the box 4 and the extension box 5 do not fall off during operation, thus completing the splicing work. The diagonal rope 3 can be hung on the user for movement. After picking up the food at the market, ice is placed inside the refrigerated drawer 27. Pressing the button on one side will rotate the rotating fan 28 to blow air into the interior and ensure the freshness of the food.
[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
