Specific implementation manners

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0026] As Figure 1-7 shown, a leak-proof and waterproof corrugated paper packaging box includes a corrugated paper packaging box body 1. The corrugated paper packaging box body 1 includes a waterproof oil film 101, a compression layer 102, a flame retardant layer 103 and a waterproof layer 104. The waterproof oil film 101, the compression layer 102, the flame retardant layer 103 and the waterproof layer 104 are bonded together by glue. A reinforcing frame 1021 is arranged inside the compression layer 102;

The top ends of the waterproof oil film 101, the compression layer 102, the flame retardant layer 103 and the waterproof layer 104 are fixedly connected with an installation frame 3. A top cover 5 is arranged above the corrugated paper packaging box body 1. The top cover 5 and the installation frame 3 are connected by a limiting mechanism. The use of tape can be avoided by the arranged limiting mechanism.

[0028] In this embodiment, the limiting mechanism includes a square groove 501 opened at the bottom end of the top cover 5. The square groove 501 and the installation frame 3 are of matching shapes. During installation, the square groove 501 is stuck on the installation frame 3 to complete the encapsulation of the corrugated paper packaging box body 1.

[0029] In this embodiment, card columns 8 are symmetrically and slidably penetrated through both ends of the top cover 5 and extend into the square groove 501. Card slots 4 matching the shapes of the card columns 8 are symmetrically opened at both ends of the installation frame 3. The top cover 5 is limited and fixed by the card columns 8 being stuck in the card slots 4.

[0030] In this embodiment, connecting columns 7 are fixedly connected to the ends of the two groups of card columns 8 far away from the top cover 5.

[0033] It should be noted that the present utility model is a corrugated paper packaging box with leak-proof and waterproof functions. During use, the waterproof oil film 101 provided can prevent water on the ground from entering and penetrating into the inside of the corrugated paper packaging box body 1, and when placed on the ground, the wear-resistant support strips 2 provided can support the corrugated paper packaging box body 1, avoiding contact with the ground, thereby reducing the wear of the corrugated paper packaging box body 1 and extending the service life. Moreover, the compressive layer 102 and the reinforcing frame 1021 can strengthen the strength of the four sides and the bottom of the corrugated paper packaging box body 1, and can increase the compressive capacity to prevent it from being crushed and damaged. The provided flame-retardant layer 103 can prevent the corrugated paper packaging box body 1 from catching fire, and the waterproof layer 104 can improve the waterproof effect inside the corrugated paper packaging box body 1, and in cooperation with the waterproof oil film 101, improve the overall waterproof effect;

[0034] And during use, pull the connecting column 7 outward and make the installation frame 3 stuck in the square groove 501. At this time, release the connecting column 7, and under the elastic reset action of the spring 6, the connecting column 7 is reset and the clamping column 8 is stuck in the clamping groove 4, completing the encapsulation of the corrugated paper packaging box body 1, and without using tape, thereby avoiding damage to the corrugated paper packaging box body 1 caused by tearing the tape, and preventing the tape from adhering to the corrugated paper packaging box body 1 and affecting the appearance.
