Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, an example provided by the present solution: the utility model provides a bottom is from locking-type dampproofing corrugated box, including carton main part 1, the bottom symmetry of carton main part 1 is fixed to be equipped with two and can turn over a cardboard 6, can turn over the fixed rectangle board 5 that can fold that is equipped with in below of a cardboard 6, waist shape hole has been seted up to the bilateral symmetry of carton main part 1, the equal activity joint in inside in waist shape hole has waist shape plastic ring 3, a plurality of ropes 7 of fixedly connected with between two waist shape plastic ring 3, the equal fixed inlaying of rope 7 is in the tank wall of carton main part 1, rope 7 is fixed to be inlayed in the inside that can fold over rectangle board 5.

In this embodiment, the outer portion of the waist-shaped hole is provided with a waist-shaped annular groove, and the inner portion of the waist-shaped annular groove is movably clamped outside the waist-shaped hole.

In this embodiment, a plurality of through holes 4 are formed in the foldable rectangular plate 5, and the through holes 4 are movably sleeved outside the rope 7.

In this embodiment, two can turn over the B face that a cardboard 6 kept away from each other all with carton main part 1's bottom inner wall fixed connection, can turn over 5 other faces that a cardboard 6 all not with carton main part 1 fixed connection.

In the embodiment, the foldable rectangular plate 5 is a cube, the foldable rectangular plate 5 is cut into two isosceles triangular plates along one diagonal line, the rope 7 is not broken, the foldable rectangular plate 5 is pre-creased along the other diagonal line, and the two foldable rectangular plates 5 can be folded around the pre-creased line A-A.
