Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, specifically to a sample storage device for food inspection and testing. Background Technology

[0002] Food testing analyzes microbial indicators in food samples to determine whether they contain excessive levels of pathogenic bacteria or illegal additives. To ensure the accuracy of test results, samples must be immediately sealed and stored after collection to prevent microbial proliferation due to environmental exposure during delivery and testing. Therefore, sample storage equipment must meet the requirements of airtightness and sterility to prevent contamination of samples by harmful bacteria in the air, thereby ensuring that the data obtained during the testing process truly reflects the actual safety status of the food.

[0003] Chinese Patent Publication No. CN218594924U discloses a sample storage device for product inspection and testing, relating to the field of sample storage technology. The device includes a storage box with a freely movable protective door. Adjustment grooves are formed on both inner side walls of the storage box, and a fixed shaft is fixedly installed inside each of the two adjustment grooves. Guide grooves are also formed on both inner side walls of the storage box. In this invention, through the equally spaced partition holes, a large gap is created between the test tubes after they are stored inside the test tube clamping plate, preventing collisions during transport. Simultaneously, the test tube clamping plate can move between the two guide grooves via two guide rollers on the side walls. When storing or retrieving test tubes, the entire test tube clamping plate can be pulled out of the storage box, making it convenient for storing test tubes of different lengths.

[0004] However, in actual use, this utility model has the following problems: all the samples to be tested are in one space. When storing and taking out samples, the temperature of the entire chamber will be affected, which will affect other samples and may cause cross-infection and contamination of the samples, thus affecting the final test results.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a sample storage device for food inspection and testing. In this embodiment, the structure of the sample storage device for food inspection and testing is improved so that it has the advantage of independent storage.

[0026] Example 1:

[0027] Please see Figures 1 to 2A servo motor 2 is fixedly connected to the top of the base plate 1. Eight isolation plates 7 are fixedly connected to the top of the support plate 6. A support column 8 is fixedly connected to the top of the support plate 6. One end of the eight isolation plates 7 is fixedly connected to the outer surface of the support column 8. Ventilation holes are opened on the outer surface of the support column 8. A test tube rack 16 is placed on the upper end of the support plate 6. A support leg 13 is fixedly connected to the top of the base plate 1. A shell 12 is fixedly connected to the top of the support leg 13. A cabinet door 14 is connected to the outer surface of the shell 12 by a hinge. A useful observation window is opened on the outer surface of the cabinet door 14. A handle 15 is fixedly connected to the outer surface of the cabinet door 14. A rubber sleeve for anti-slip is fixedly connected to the outer surface of the handle 15. A rubber pad for anti-slip is fixedly connected to the bottom of the base plate 1.

[0028] With the support plate 6, eight isolation plates 7 are fixedly installed on the top of the support plate 6. The function is to isolate the space above the isolation plate 7 into individual small compartments. Each individual small compartment holds a test tube rack 16 to securely place test tubes for storing samples. Ventilation holes are opened on the outer surface of the support column 8 fixedly connected to the support plate 6, so that the cold air at the top can enter each independent space to avoid cross-contamination. The support leg 13 provides stable support, and the outer shell 12 fixedly connected to the top of the support leg 13 protects the samples. The outer surface of the cabinet door 14 has a useful observation window, which allows for easy observation of the storage status of the samples at any time. The outer surface of the cabinet door 14 is fixedly connected to a handle 15, which can be used to open and close the cabinet door 14 for easy storage and retrieval of samples to be tested.

[0029] Example 2:

[0030] Please see Figures 2 to 3 In order to rotate the support plate, a servo motor 2 is installed at the top of the base plate 1. The output end of the servo motor 2 is fixedly connected to a quarter gear 3. The outer surface of the quarter gear 3 is meshed with a driven gear 4. The top of the base plate 1 is rotatably connected to a drive shaft 5. The outer surface of the drive shaft 5 is fixedly connected to the inner wall of the driven gear 4. The other end of the drive shaft 5 is fixedly connected to a support plate 6. The top of the outer shell 12 is fixedly connected to a fixing ring 9. The inner wall of the fixing ring 9 is fixedly connected to a glass plate 10. The other side of the glass plate 10 is fixedly connected to a support column 8. The top of the support column 8 is fixedly connected to a cooling module 11.

[0031] With the servo motor 2 in place, the servo motor 2 can provide power for the rotation of the quarter gear 3. Since the outer surface of the driven gear 4 meshes with the outer surface of the quarter gear 3, the quarter gear 3 drives the driven gear 4 to rotate. The inner wall of the driven gear 4 is fixedly connected to the outer surface of the transmission shaft 5, which drives the transmission shaft 5 to rotate. One end of the transmission shaft 5 is fixedly connected to the support plate 6, which drives the support plate 6 to rotate. This allows the isolation plate 7 to rotate in the space separated on the top of the support plate 6, making it convenient to take out and store samples in each space. The inner wall of the outer shell 12 is fixedly connected to the glass plate 10, which allows the status of all stored samples to be clearly observed from above. The cooling module 11 is fixedly installed above the support column 8. The surface of the support column 8 is full of ventilation holes, which allow the lighter cold air to enter the small spaces below through the ventilation holes to achieve the effect of low temperature preservation.

[0032] Example 3:

[0033] Please see Figures 3 to 4 In order to make the test tubes more stable, a test tube rack 16 is placed on the upper end of the support plate 6. The base of the test tube rack 16 is fixedly connected with a rubber pad for anti-slip, and the top of the outer shell 12 is fixedly connected with a glass cover 17 for shielding.

[0034] The test tube rack 16 is placed on the upper end of the support plate 6, which allows the sample to be tested to be placed stably in the small space for storage. A rubber pad is added to the bottom of the test tube rack 16 to make the whole placement more stable. A glass cover 17 is added to the top of the outer shell 12, which can serve to observe the sample status, shield and protect it.

[0035] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0036] In this invention, the working steps of the device are as follows:

[0037] First, place the equipment in an empty area of ​​the laboratory and open the cabinet door 14. Then, place the prepared test tubes into the test tube rack 16 in sequence. Depending on the sampling time, the test tube rack 16 can be placed into the space separated by the isolation plate 7 on the top of the support plate 6. Next, turn on the upper cooling module 11 to preserve all samples at low temperature. The status of the samples can be viewed through the upper glass plate 10 and the observation window. When it is necessary to take the sample, the servo motor 2 can be started. Driven by the servo motor 2, the quarter gear 3 and the driven gear 4 are rotated, which in turn rotates the support plate 6. When the sample reaches the cabinet door 14, observe through the observation window, glass cover 17 and glass plate 10 on the surface of the cabinet door 14. Then, turn off the servo motor 2, open the cabinet door 14 and take out the sample.
