Description

Technical Field

[0001] The utility model relates to the technical field of food preservation boxes, in particular to a food preservation box. Background Art

[0002] Food inspection refers to a discipline that studies and evaluates food quality and its changes. It is based on some basic theories and various technologies of physics, chemistry and biochemistry, and in accordance with established technical standards, such as international and national food hygiene and safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products and by-products to ensure the quality of the products. In the process of food inspection, food preservation boxes are often used to store and transport food samples.

[0003] The announcement number authorized by China is CN217865566U, and it is named a patent for a food preservation box for food inspection. The device includes a box body, a partition box, a slot and a locking mechanism arranged on the surface of the box body, the partition box fits into the interior of the box body, the slot is fixedly connected to the surface of the partition box, and the locking mechanism includes a transmission component and a fixing component; the transmission component includes a slide bar, a sliding plate and a nut. By setting the sliding plate, it is only necessary to rotate the nut to disengage it from the surface of the box body, and then pull the slide bar downward, and the sliding plate fixedly connected to the slide bar will move downward accordingly, and then the convex rod on the sliding plate will then slide along the surface of the rotating plate and drive the rotating plate to swing downward, and then the card plate connected to the box body through a spring will pop out of the slot, and then the partition box will lose its fixed state, and finally the partition box can be taken out from the inside of the box body for cleaning.

[0004] Although the above device is easy to clean, there are still some problems when using the device:

[0005] 1. The device does not have a test tube anti-jump structure, and food inspection often requires the use of test tubes to store food samples. When the device stores and transports test tubes, the test tubes can easily collide with the internal structure of the device due to bumps, causing the test tubes to break and the samples to leak. It is also easy to cut people's hands during cleaning, creating safety hazards.

[0006] 2. The device does not have a heat preservation and refrigeration mechanism. Food samples stored in the device are prone to spoilage, resulting in inaccurate test results.

[0007] In view of the above situation, technical innovation is carried out on the basis of the existing food preservation boxes. Utility Model Content

[0008] The purpose of the utility model is to provide a food preservation box to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a food preservation box, comprising an insulation box cover and an insulation box body, a hand-pressure air pump is fixed to one side of the top of the insulation box cover, and an exhaust valve is fixed to the end of the top of the insulation box cover away from the hand-pressure air pump, a telescopic air bag is fixed to the bottom wall of the insulation box cover, and a pressure plate is fixed to the bottom end of the telescopic air bag, a foam layer is provided at the bottom end of the pressure plate, and the foam layer and the pressure plate are adhesively fixed, the insulation box body is arranged at the bottom end of the insulation box cover, and a test tube rack is fixed to the top of the inner wall of the insulation box body, and sample test tubes are placed on the inner side of the test tube rack, and the sample test tubes are test tubes with covers.

[0012] Furthermore, a hollow trap door is hinged on the top of the breathable mesh plate, and two magnetic blocks are inlaid and fixed on the bottom walls at the left and right ends of the hollow trap door.

[0013] Furthermore, an ice bag is arranged at the inner bottom end of the heat preservation box, and a plurality of ice bags are arranged.

[0014] Furthermore, universal wheel assemblies are fixed on both left and right sides of the bottom end of the thermal insulation box body, and the universal wheel assembly includes a rotating mechanism and a locking caster, and a locking caster is fixed on the bottom end of the rotating mechanism.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the device is provided with a squeezing mechanism, which can press the sample test tube, thereby preventing the test tube from being broken due to bumping and jumping during transportation and movement, which is beneficial to improving the safety of the device; at the same time, the device is provided with an ice bag cooling mechanism, which can effectively reduce the storage temperature of the device and prolong the storage time of food, which is beneficial to improving the practicality of the device.

[0016] 1. The utility model is provided with an insulated box cover, a hand pressure air pump, an exhaust valve, a telescopic air bag, a pressing plate, a foam layer, a test tube rack and a sample test tube. When a user uses the device to transport the test tube, the hand pressure air pump can be pressed, and the air outlet of the hand pressure air pump is connected to the telescopic air bag. When the user presses the hand pressure air pump, the hand pressure air pump will inflate the telescopic air bag to make the telescopic air bag expand. At this time, the telescopic air bag will drive the pressing plate and the foam layer to press down, thereby pressing the sample test tube on the test tube rack to avoid excessive transportation. During the process, the sample test tube jumps due to the bumps, causing the sample test tube to be broken. The foam layer can effectively ensure that each sample test tube can contact the squeezing mechanism. The exhaust valve is connected to the telescopic airbag, and the telescopic airbag is an elastic airbag. When the exhaust valve is opened, the telescopic airbag will shrink under its own resilience, and then discharge the gas from the exhaust valve 3. Through the above structure, the device can press the sample test tube, thereby preventing the test tube from being broken due to bumps and jumps during transportation and movement, which is beneficial to improving the safety of the device.

[0017] 2. The utility model is provided with a breathable mesh plate, a magnetic block 1, a hollow trap door, a magnetic block 2 and an ice bag. The ice bag can be a pure water ice bag or a dry ice ice bag. The ice bag can effectively reduce the internal temperature of the heat preservation box. In addition, the heat preservation performance of the heat preservation box and the heat preservation box cover is good, and the ice bag melts slowly. Therefore, the heat preservation box can maintain a low temperature for a long time, which is convenient for storing food samples and effectively slows down the deterioration rate of food samples. The breathable mesh plate and the hollow trap door can block the ice bag, effectively preventing the ice bag from jumping up and contacting the sample test tube during transportation. The hollow trap door is hinged to the breathable mesh plate, and the open end of the hollow trap door is attracted to the breathable mesh plate by the magnetic block 1 and the magnetic block 2, which can prevent the hollow trap door from being opened. When the user needs to replace the ice bag, the hollow trap door can be opened for replacement. Through the above structure, the storage temperature of the device can be effectively reduced, the shelf life of food can be extended, and the practicality of the device can be improved.
