[0030] The utility model provides a kind of fresh-keeping box with self-locking function in combination with the drawings and specific embodiments is described in detail below.It is explained here that, in order to make embodiment more detailed, the following embodiment is best, preferred embodiment, for some known technology, other alternative ways can also be used by the person skilled in the art to be implemented;And the part of drawing is only for more specific description of embodiment, and is not intended to be specific to the utility model.

[0031] As Figures 1-8 Indicated, the embodiment of the utility model provides a kind of fresh-keeping box with self-locking function, including box body 1, box body 1 is covered with box cover 2, box body 1 and box cover 2 can be square also can be circular, further include:

[0032] The storage grid 5 is placed in the box body 1, and the storage grid 5 can be square or circular. A cavity is arranged between the bottom of the storage grid 5 and the inner wall bottom of the box body 1, and the cavity is used for storing low-temperature medium, and the low-temperature medium is ice. The side of the box body 1 is fixed with a hollow shaft 14, the circumferential surface of the hollow shaft 14 is sleeved with a U-shaped handle 4, the hollow shaft 14 is inserted with a latch 15 for positioning the U-shaped handle 4, and the end of the U-shaped handle 4 is provided with a lock catch 7. The side of the box cover 2 is provided with an arc block 13, the lock catch 7 is buckled on the arc block 13 for locking the box cover 2. The box body 1 and the box cover 2 form the basic shell of the fresh-keeping box, and provide a closed space for internal storage. The plurality of storage grids 5 can classify and place different types of fruits or vegetables or fruits or vegetables that need to be stored separately, so that the inside of the fresh-keeping box is more organized. The ice is placed between the bottom of the storage grid 5 and the bottom of the box body 1 to reduce the temperature in the storage grid 5, create a low-temperature fresh-keeping environment, inhibit the growth of bacteria, prolong the fresh-keeping period of fruits or vegetables, improve the fresh-keeping capacity of the fresh-keeping box, and provide a rotating support point for the U-shaped handle 4.
