[0021] The carton body 1 is installed on the top of the waterproof base 2, and the waterproof base 2 is in contact with the ground. At the same time, the interior of the waterproof base 2 is provided with a double waterproof structure. The first waterproof layer 3 made of waterproof oil paper cooperates with the second waterproof layer 5 to effectively avoid the problem of damage to the carton due to moisture at the bottom of the carton. The protective layer 4 made of fiber material enhances the tensile strength of the waterproof base 2, so that the waterproof base 2 will not be easily damaged, thereby increasing the service life of the product.

[0022] The top of one of the carton cover plates 7 is symmetrically connected to an auxiliary plate 8 with a U-shaped cross-section, and the top of the other carton cover plate 7 is symmetrically installed with a hollow plate 9, a rectangular hole 10 is opened on the top of the hollow plate 9, a push plate 11 is slidably installed inside the rectangular hole 10, and the bottom of the push plate 11 is fixedly connected to a plug plate that is compatible with the auxiliary plate 8.

[0023] The two carton cover plates 7 respectively drive the auxiliary plate 8 and the hollow plate 9 with a U-shaped cross-section to move. When the two carton cover plates 7 are close to each other, the push plate 11 is pushed by the rectangular hole 10, and the push plate 11 drives the insertion plate to move. The insertion plate penetrates the auxiliary plate 8 to achieve the initial positioning of the two carton cover plates 7.

[0024] A round rod 12 penetrating the push plate 11 is threadedly mounted on one side of the hollow plate 9 , and a return spring is arranged outside the round rod 12 and inside the rectangular hole 10 , and the central axis of the round rod 12 coincides with the central axis of the return spring.

[0025] In order to prevent the insert plate from penetrating the auxiliary plate 8 and sliding out, causing the carton cover 7 to open, a round rod 12 is threadedly installed on one side of the hollow plate 9, and the round rod 12 passes through the rectangular hole 10. At the same time, a reset spring is installed on one side of the push plate 11. Under the action of the reset spring, the insert plate can be kept in a pushed-out state at all times, thereby realizing the positioning of the two carton cover plates 7.

The protective layer 4 made of fiber material enhances the tensile strength of the waterproof base 2, so that the waterproof base 2 will not be easily damaged, thereby increasing the service life of the product.

[0032] Step 2: When it is necessary to disassemble and assemble the vertical plate 13 and the working plate 15 inside the carton body 1, the auxiliary pull rod 17 is installed under the action of the threaded hole 16, and the vertical plate 13 and the working plate 15 are conveniently taken by moving the auxiliary pull rod 17.

[0033] Step 3: When the two carton cover plates 7 are close to each other, the push plate 11 is pushed by the rectangular hole 10, and the push plate 11 drives the plug plate to move, and the plug plate passes through the auxiliary plate 8. In order to prevent the plug plate from slipping out after passing through the auxiliary plate 8, which causes the carton cover plate 7 to open, a round rod 12 is threadedly installed on one side of the hollow plate 9, and the round rod 12 passes through the rectangular hole 10. At the same time, a reset spring is installed on one side of the push plate 11. Under the action of the reset spring, the plug plate can be kept in a pushed-out state at all times, thereby realizing the positioning of the two carton cover plates 7.
