Description

Technical Field

[0001] The utility model relates to the technical field of food insulation bags, in particular to a food insulation bag with a layered structure. Background Art

[0002] Food insulation bags are bags used to hold various foods and keep the food temperature and fresh. They can be used for outdoor picnics or daily life, so that the food can still have a certain temperature and retain most of the taste and taste for a period of time after the food is cooked.

[0003] As the demand of urban residents for getting closer to nature continues to increase, people are more and more inclined to go camping and picnicking in parks, natural scenic spots and other places full of natural atmosphere during holidays. During the camping and picnicking process, some food is often prepared in advance. In order to ensure that the food has a better taste and texture when eaten after arriving at the picnic camp, it is usually necessary to place the food in an insulation bag for insulation storage.

[0004] The Chinese utility model patent with patent application number CN202221144149.3 records a food insulation bag with a temperature display, which insulates the food placed in the bag well by providing a bag body, an inner lining, an insulation layer and a waterproof layer. At the same time, the upper edge of the waterproof layer is connected to the upper edge of the bag body by sewing lines, so that the waterproof layer can be turned out for easy cleaning. However, when storing food in the above-mentioned food insulation bag, the food is stacked in the internal space of the bag body. When people carry the food insulation bag to move, if the food insulation bag shakes significantly, the food placed inside will shake or even fall over, which may cause the soup in the food with soup to spill, and then cause all the food in the insulation bag to be stained with the soup, which seriously reduces the subsequent dining experience. At the same time, the entire internal space of the bag needs to be cleaned, making the cleaning work more troublesome. Utility Model Content

[0005] The purpose of the present application is to provide a food insulation bag with a layered structure to solve the problem proposed in the above background technology that when storing food, the existing food insulation bag is piled in the internal space of the bag. When the food soup is spilled, all the food in the insulation bag will be stained with the soup, which seriously reduces the subsequent dining experience.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a food insulation bag with a layered structure, comprising an outer body, a first cover is provided on the top of the outer body, the first cover is connected to the top of the outer body through a first zipper, two handles are symmetrically provided on the front and rear sides of the outer body, a plurality of inner bodies are stacked in sequence from bottom to top in the inner cavity of the outer body, a second cover is provided on the top of the inner body, and the second cover is connected to the top of the inner body through a second zipper.

At the top of the plate, the two support plates located on the uppermost side are located on the top of the uppermost inner package. The advantage of such a configuration is that a plurality of inner packages can be supported and stabilized by the support rods and the support plates, the support rods and the support frame can reduce the pressure transmitted to the inner package after the outer package is squeezed, and prevent the inner package from deforming, and the support plates can prevent the two upper and lower adjacent inner packages from being severely squeezed, thereby ensuring the safety of the food in the inner package, and at the same time preventing the inner package from shaking in the inner cavity of the outer package, thereby reducing the shaking amplitude of the food in the inner package, preventing the food in the inner package from spilling, and improving the reliability of the thermal insulation bag.

[0008] Preferably, it also includes a tensioning component arranged in the outer body, and the tensioning component is used to tighten and stabilize the inner body. The advantage of such a setting is that it can cooperate with the stabilizing component to further improve the stability of the inner body in the inner cavity of the outer body, thereby further improving the reliability of the insulation bag.

[0009] Preferably, the tensioning assembly includes two groups of slide grooves symmetrically opened on the adjacent sides of the two groups of support rods, each group of the slide grooves has two slide grooves, and a plurality of iron blocks are arranged in the slide grooves from top to bottom, and the number of iron blocks in each slide groove is equal to the number of inner enclosures. The tensioning assembly also includes two groups of fixed cloth sleeves fixedly connected to the left and right sides of the inner enclosure, each group of the fixed cloth sleeves has two fixed cloth sleeves, and the ends of the two groups of fixed cloth sleeves that are away from each other are fixedly sleeved with magnetic blocks, and the four magnetic blocks on the inner enclosure are respectively slidably connected to the two groups of slide grooves, and the magnetic blocks on the plurality of inner enclosures are respectively adsorbed by the two groups of iron blocks, and the tensioning assembly also includes a driving unit, which is used to drive the iron blocks to move so as to be adsorbed with the magnetic blocks.

[0010] Preferably, the driving unit includes two groups of second damping rotating shafts symmetrically and rotatably connected on the adjacent sides of the two groups of support rods, the number of the second damping rotating shafts in each group is equal to and corresponds to the number of the first damping rotating shafts in each group, the front and rear ends of the second damping rotating shaft respectively penetrate into the interior of the front and rear two sliding grooves, and the two iron blocks at the same height in each group of two sliding grooves are symmetrically and fixedly sleeved on the outer circumferences of the front and rear ends of the second damping rotating shaft, the outer circumference of the second damping rotating shaft is symmetrically and fixedly sleeved with two first driving wheels, and the driving unit also includes two second driving wheels symmetrically and fixedly sleeved on the outer circumference of the first damping rotating shaft, the outer circumference of the first driving wheel is adjacent to the outer circumference of the first driving wheel. The outer peripheral surface of the second driving wheel conflicts with each other. The advantage of such a setting is that when placing several inner bodies in the inner cavity of the outer body from bottom to top in sequence, the support plate can be rotated synchronously from bottom to top in sequence, and then the support plate drives the first damping shaft to rotate. The first damping shaft drives the corresponding iron block to rotate through the second driving wheel, the first driving wheel and the second damping shaft to reduce the distance between the iron block and the magnetic block, so that the iron block and the magnetic block can be adsorbed together, ensuring that the tensioning assembly can work normally. In the process of placing the inner body, the iron block is rotated in the opposite direction away from the magnetic block, so that the magnetic block will not be adsorbed with the iron block during the placement process, ensuring that the inner body can be smoothly placed in the inner cavity of the outer body.

[0033] Specifically, when placing several inner enclosures 2 in the inner cavity of the outer enclosure 1 from bottom to top, the support plate 34 can be rotated synchronously from bottom to top, and then the support plate 34 drives the first damping shaft 33 to rotate. The first damping shaft 33 drives the corresponding iron block 42 to rotate through the second driving wheel 453, the first driving wheel 452 and the second damping shaft 451 to reduce the distance between the iron block 42 and the magnetic block 44, so that the iron block 42 and the magnetic block 44 can be adsorbed together to ensure that the tensioning assembly 4 can work normally. In the process of placing the inner enclosure 2, the iron block 42 is rotated in the opposite direction away from the magnetic block 44, so that the magnetic block 44 will not be adsorbed with the iron block 42 during the placement process, thereby ensuring that the inner enclosure 2 can be smoothly placed in the inner cavity of the outer enclosure 1.
