Description

Technical Field

[0001] This utility model relates to the field of pre-prepared food processing technology, specifically a pre-prepared food preservation and transportation box. Background Technology

[0002] Pre-cooked meals eliminate the hassle of sourcing ingredients and simplify the preparation process. After being packaged hygienically and scientifically, they can be cooked directly as convenient and special dishes on the table by heating or steaming / stirring. To ensure their freshness, pre-cooked meals need to be refrigerated at low temperatures during transportation. In current technology, pre-cooked meals are packaged in box form, and these boxes are usually stacked in refrigerated transport containers for transportation.

[0003] A search revealed a utility model patent in China, Chinese Patent Publication (Announcement) No. CN221893154U, which discloses a pre-prepared vegetable preservation and transportation box. The general description includes a base plate, with a preservation box fixedly connected to one side of the upper surface of the base plate. The inner walls of the preservation box have grooves on both sides. In use, several sliders are installed inside the grooves, facilitating the sliding of several connecting plates inside the preservation box. Several springs connect adjacent protective plates. When several pre-prepared vegetable packaging boxes are placed between two protective plates, the outward force exerted by the springs on the protective plates restricts the movement of the pre-prepared vegetable packaging boxes inside the preservation box. The above-mentioned device achieves the effect of preventing the pre-prepared food packaging boxes from shaking and colliding during transportation, which could easily cause the pre-prepared food to spill. However, the above-mentioned device still has some shortcomings. For example, when transporting pre-prepared food packaging boxes, it is sometimes necessary to open the refrigerated box multiple times to take out a small number of pre-prepared food packaging boxes. However, the above-mentioned device directly opens the lid each time the refrigerated box is opened to take out the pre-prepared food packaging boxes, which will result in a lot of cold air leakage. Moreover, the above-mentioned device is not convenient for accurately classifying the pre-prepared food packaging boxes. It takes time to search for the packaging boxes when taking them out, which further accelerates the leakage of cold air and reduces the refrigeration and preservation effect. Therefore, we propose a pre-prepared food preservation and transportation box. Utility Model Content

Limiting mechanisms are set on the opening, the support plate 6, and the placement rack 5. Spring 1 is used to provide elastic force. Clamping plate 10 and placement frame 8 are used to limit the placement of pre-made food packaging boxes of different sizes. Staff can write on the label 12 to achieve the purpose of classifying pre-made food packaging boxes. It is used to reduce the leakage of cold air when taking them out. Slider 1 4 and slide 1 are used to improve the stability of the placement rack 5 and limit the placement rack 5, avoiding direct removal of the placement rack 5.

[0016] The limiting mechanism includes a second slide groove and two slots 13. The second slide groove is opened in the opening, and the two slots 13 are respectively opened on the support plate 6 and the placement frame 5. A second slider 14 is slidably connected in the second slide groove. Two springs 2 are provided between the second slider 14 and the second slide groove. A control block 15 is fixedly connected to the second slider 14. The control block 15 passes through the second slide groove through the control port. One end of the second slider 14 is located in one of the slots 13. The second spring is used to provide elastic force. The second slider 14 is used to lock into the slot 13 for limiting and fixing the support plate 6 or the placement frame 5.

[0017] A threaded shaft 16 is rotatably connected to the placement rack 5. Two threaded tubes are threadedly fitted onto the threaded shaft 16. A pressure plate 17 is fixedly connected to each of the two threaded tubes. Through holes are opened on both placement plates 7. The threaded shaft 16 is located in the two through holes. The threaded shaft 16 passes through the support plate 6 and is fixedly connected to an adjustment knob 18, which is used to lower and press down on the pre-prepared food packaging box, thereby improving the stability of the pre-prepared food packaging box.

The pull ring 19 is used to facilitate the movement of the clamping plate 10, and the handle is used to facilitate the movement of the entire device in conjunction with the self-locking rollers.

[0019] A mesh plate 20 is fixedly connected inside the food storage box 2. Due to the characteristic that cold air flows downwards, cold air circulates under the mesh plate 20, which helps to improve the preservation effect inside the food storage box 2.

[0020] The support plate 6 has an annular groove, and a sealing ring gasket 21 is provided on the annular groove to seal and prevent cold air leakage.

[0021] It should be further explained that the refrigeration unit 3 in this embodiment is a conventional device known to those skilled in the art and available on the market. The model can be selected or customized according to actual needs. In this patent, we only use it without improving its structure and function. Its setting method, installation method and electrical connection method can be adjusted and operated by those skilled in the art according to the requirements of its instruction manual. It will not be described in detail here. The refrigeration unit 3 is equipped with a matching control switch. The installation position of the control switch can be selected according to the actual use needs to facilitate the operation and control by the operator.

[0022] In summary, the working principle and process of this pre-prepared vegetable preservation and transportation box are as follows: First, the pre-prepared vegetable preservation and transportation box is placed at the desired location. Then, when in use, the refrigeration unit 3 is started. The refrigeration unit 3 generates cold air, which is delivered into the interior of the preservation box 2 through a flexible hose to achieve the function of refrigeration and preservation. It should be noted that when moving the entire device, a corresponding battery can be provided for the refrigeration unit 3 to operate. The battery is a common device on the market, and the model can be selected or customized according to actual needs. Specific details will not be described here. Then, when removing the pre-prepared vegetable packaging box, the control block 15 moves the slider 14, which compresses the spring 2, causing the slider 14 to move out of the support plate 6. With the slot 13 on the top, use the handle 11 to pull the support plate 6, the placement rack 5, and the slider 4 upwards. When the placement rack 5 moves to its limit, release the control block 15, the spring 2 returns, and the slider 2 14 enters the slot 13 of the placement rack 5. Then, rotate the adjustment knob 18 and the threaded shaft 16. The threaded shaft 16 will drive the threaded tube and the pressure plate 17 to move. The pressure plate 17 moves up and down within the placement rack 5. After the pressure plate 17 no longer limits the pre-prepared food packaging box, the pull ring 19 can be used to move the clamping plate 10. The clamping plate 10 squeezes the spring 1 and the telescopic rod 9, thereby removing the pre-prepared food packaging box. This makes it easy to accurately remove the corresponding pre-prepared food and avoids a large amount of cold air leakage, which is conducive to better refrigeration and preservation of pre-prepared food.

[0023] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
