The bottom sealing frame 2 6 A partition plate 27 is fixedly connected to the top, and a vertical partition plate 28 is provided on the top of the partition plate 27. A bayonet is provided at the front and rear ends of the partition plate 27. One end of the surface of the T-shaped round bar 24 matches the inside of the bayonet. A circular groove is provided at the front and rear ends of the interior of the box body 1. The surface of the ring 22 is rotatably connected to the inside of the circular groove. A sealing hole is provided at the top of the box body 1. The surface of the sealing sleeve 241 is tightly fitted in the sealing hole. The surface of the vertical rod 23 is tightly fitted in the inside of the sealing sleeve 241. A circular cavity is provided inside the four ends of the box body 1. The surface of the T-shaped rod 29 is slidably connected to the inside of the circular cavity. A through hole is provided at the top of the circular cavity. The surface of the T-shaped rod 29 passes through the through hole provided at the top of the circular cavity.

[0031] Furthermore, a partition groove is provided on the top of the partition plate 27, and the lower surface of the vertical partition plate 28 is plugged into the interior of the partition groove. The bottom sealing frame 26 on the partition plate 27 penetrates into the interior of the box body 1 to seal the bottom layer, and when the partition plate 27 moves downward, it drives the T-shaped rod 29 downward and elastically compresses the second spring 291 to a certain depth, and then rotates the lever 25 to drive the vertical rod 23 to rotate, thereby driving the T-shaped round bar 24 to be stuck into the notch inside one end of the partition plate 27 during rotation, thereby fixing the partition plate 27 in position, and while ensuring the sealing of the bottom layer, it can play a corresponding stratification role.

[0032] Example 2

[0033] See Figure 1-6 , and on the basis of Example 1, it is further obtained that the sealing mechanism 3 includes a support 31, there are two supports 31, the two supports 31 are fixedly connected to the left and right sides of the box body 1 respectively, one end of the support 31 is fixedly connected to the third spring 32, the front end of the third spring 32 is fixedly connected to the T-shaped rod 33, a connecting strip 34 is provided on the surface of the T-shaped rod 33, the top of the connecting strip 34 is rotatably connected to the inside of the card rod 36, the surface of the card rod 36 is rotatably connected to the door-shaped strip 35, one side of the door-shaped strip 35 is fixedly connected to the cover plate 38, the bottom end of the cover plate 38 is fixedly connected to the top sealing frame 39, the top of the box body 1 is fixedly connected to the inside of the sealing groove seat 37, the top of the sealing groove seat 37 is provided with a sealing frame groove, and the surface of the top sealing frame 39 is tightly fitted with the inside of the sealing frame groove.

[0034] Furthermore, a circular hole is opened inside the support 31, and the surface of the T-shaped rod 33 is slidably connected to the circular hole. The top sealing frame 39 under the cover 38 is buckled inside the sealing groove seat 37 to seal the inside of the box body 1. In addition, the T-shaped rod 33 is pulled open to move, and then after the cover 38 is closed, the connecting strip 34 is rotated to one end of the T-shaped rod 33. At this time, the T-shaped rod 33 is inserted into the perforation inside the connecting strip 34, so that the cover 38 can be fixed and limited after being closed, thereby preventing the cover 38 from falling off.

At this time, the bottom sealing frame 26 on the partition plate 27 penetrates into the box body 1 to seal the bottom layer. When the partition plate 27 moves downward, it drives the T-shaped rod 29 downward and elastically compresses the second spring 291 to a certain depth. Then, the lever 25 is rotated to drive the vertical rod 23 to rotate, thereby driving the T-shaped round bar 24 to engage in the notch inside one end of the partition plate 27 during rotation, thereby locking the partition plate 27 in place and ensuring the sealing of the bottom layer. It can also play a corresponding layering role.

[0036] After that, when placing the upper layer of food, a perforation is opened inside the connecting strip 34, and the vertical dividing plate 28 can separate the food. When closing the cover, the top sealing frame 39 below the cover 38 is buckled inside the sealing groove seat 37 to seal the inside of the box body 1. In addition, the T-shaped rod 33 is pulled open to move, and then after the cover 38 is closed, the connecting strip 34 is rotated to one end of the T-shaped rod 33. At this time, the T-shaped rod 33 is inserted into the perforation inside the connecting strip 34, so that the cover 38 can be fixed and limited after closing, thereby preventing the cover 38 from falling off.
