The side corners of the box cover and the box body are all anti-collision rounded corners, and the annular structure is adapted to the outer shapes of the box cover and the box body.

[0008] For further improvement, the connecting belt preferably covers one side edge of the bottom opening of the box cover, and the zipper covers three side edges of the bottom opening of the box cover.

[0009] As an improvement, a connecting lug is preferably provided on each of the left and right side walls of the box body, and a "day"-shaped movable member is provided at the end of the carrying strap. One end of the movable member is rotatably connected to the corresponding connecting lug, and the other end of the movable member is movably connected to the end of the corresponding carrying strap.

[0010] For further improvement, the connecting lug and the box body are preferably an integrally formed integral structure.

[0011] For further improvement, an annular reinforcing rib is preferably provided on the outer wall of the box body corresponding to the connecting lug.

[0012] As an improvement, a water collecting trough is preferably provided on the top of the box cover.

[0013] As an improvement, friction strips are preferably distributed at the bottom of the box body.

[0014] Compared with the prior art, the advantages of the present utility model are as follows: both the box cover and the box body are made of EVA material, with soft texture, wear resistance, and good heat preservation effect; the structure of this application is simple, the whole is light, the backpack straps are comfortable, and it is convenient to carry, with a long service life; the carrying strap is connected to the bag body through the connecting lug, and the end of the carrying strap has a large degree of freedom and good fixing effect, further extending the service life of the insulation box.
