DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4 In the embodiment, the corrugated paper box with the anti-tearing function comprises a reinforcing frame 1, a footing 3 is installed at the bottom of the reinforcing frame 1, corner columns 14 are fixedly connected to the four corners of the upper surface of the bottom of the reinforcing frame 1, a buffer air cushion 2 is arranged on the upper surface of the bottom of the reinforcing frame 1, the buffer air cushion 2 is made of plastic film and filled with gas, the buffer air cushion 2 is fixedly connected to the bottom of the reinforcing frame 1 through double-sided adhesive or glue, and a box 4 is arranged on the upper part of the buffer air cushion 2.

[0024] The box 4 is placed along the four corner columns 14 of the reinforcing frame 1, the bottom of the reinforcing frame 1 is further provided with four footings 3, the box 4 is reinforced by the reinforcing frame 1 and the footings 3, so that the box 4 is not easily deformed and torn, the buffer air cushion 2 is pasted on the bottom of the reinforcing frame 1, can absorb and disperse energy, reduce the direct action of external force on the paperboard of the paper box, and avoid tearing of the paperboard due to excessive instantaneous impact force.

[0025] The box 4 is externally provided with a handle 6, which is fixedly installed on the front and back of the box 4, facilitating the taking out and putting in of the box 4. The box 4 internally comprises a first base layer 9, the outer side of which is attached to a shock-absorbing layer 10, the outer side of which is attached to a corrugated core paper 11, the outer side of which is attached to a second base layer 12. The first base layer 9 and the second base layer 12 are made of kraft paper, which can well achieve moisture-proof and damp-proof. The material of the box 4 is also provided with a shock-absorbing layer 10, which has the same effect as the air cushion 2. The corrugated core paper 11 is V-shaped corrugated and has high compressive strength and elasticity. The use of raw materials is also relatively reasonable, and it is a widely used corrugated shape at present.

[0026] The box 4 is externally provided with a handle 6, which is fixedly installed on the front and back of the box 4, facilitating the taking out and putting in of the box 4. The box 4 internally comprises a first base layer 9, the outer side of which is attached to a shock-absorbing layer 10, the outer side of which is attached to a corrugated core paper 11, the outer side of which is attached to a second base layer 12. The first base layer 9 and the second base layer 12 are made of kraft paper, which can well achieve moisture-proof and damp-proof. The material of the box 4 is also provided with a shock-absorbing layer 10, which has the same effect as the air cushion 2. The corrugated core paper 11 is V-shaped corrugated and has high compressive strength and elasticity. The use of raw materials is also relatively reasonable, and it is a widely used corrugated shape at present.

[0027] The wrench 801 is placed flat to the horizontal position, at which time the spring 805 is loose. Since the rotating block 803 is fixedly connected to the wrench 801 through the cylinder 804, rotating the wrench 801 adjusts the bottom rotating block 803 to the same position as the groove on the connecting block 5, so that the rotating block 803 passes through the groove. When the bottom of the fixed block 7 and the upper surface of the connecting block 5 are tightly attached, it indicates that the box cover 13 has been tightly covered. We only need to rotate the wrench 801 to make the rotating block 803 deviate from the position of the groove, and rotate the wrench 801 by 90° to make it vertical. At this time, the wrench 801 drives the rotating block 803 to move upward through the cylinder 804. The upward movement of the rotating block 803 extrudes and contracts the spring 805, so that the rotating block 803 tightly attaches to the bottom surface of the connecting block 5. Because of the force of the spring 805, it will not be loose. The operation is simple and can stably seal the box 4.

[0028] In the implementation, the following steps are performed:

[0029] 1) First, place the box 4 along the corner column 14, and then place the items to be transported into the box 4;

[0030] 2) Then cover the box cover 13, rotate the wrench 801 to make the rotating block 803 pass through the groove on the connecting block 5, at which time the connecting block 5 and the fixed block 7 are tightly attached. Rotate the wrench 801 to make it vertical and contract the spring 805, and the sealing is completed;

[0031] 3) Finally, when taking out, the plate wrench 801 is loosened to the horizontal spring 805, and the rotating handle 801 drives the rotating block 803 and the groove on the connecting block 5 to the same position, and then it can be taken out.

[0032] In summary, the corrugated carton with anti-tearing function, the box body 4 is placed along the four corner columns 14 of the reinforcing frame 1, and the reinforcing frame 1 at the bottom is also provided with four footings 3, which can play a reinforcing role on the box body 4 through the wrapping of the reinforcing frame 1 and the footings 3, so that it is not easy to deform and tear. The reinforcing frame 1 at the bottom is pasted with a buffer air cushion 2, and the material inside the box body 4 is also provided with a shock-absorbing layer 10, which can absorb and disperse energy, reduce the direct action of external force on the paperboard of the carton, and avoid tearing of the paperboard due to excessive instantaneous impact force. The first base layer 9 and the second base layer 12 of the box body 4 are both kraft paper, which can well prevent moisture and humidity. The self-locking structure 8 is set to make it very convenient to seal the box cover 13. The wrench 801 is placed horizontally to the horizontal position, and the spring 805 is loosened at this time. Because the rotating block 803 is fixedly connected through the cylinder 804 and the plate wrench 801, the rotating handle 801 adjusts the rotating block 803 at the bottom to the same position as the groove on the connecting block 5, so that the rotating block 803 passes through the groove. When the fixed block 7 at the bottom and the upper surface of the connecting block 5 are tightly attached, it means that the box cover 13 has been tightly covered. We only need to rotate the wrench 801 to make the rotating block 803 deviate from the position of the groove, and the plate wrench 801 is rotated by 90° to make it vertical. At this time, the wrench 801 drives the rotating block 803 to move upward through the cylinder 804, and the upward movement of the rotating block 803 extrudes the spring 805 to shrink, so that the rotating block 803 is tightly attached to the bottom surface of the connecting block 5. Because of the force of the spring 805, it will not be loosened. The operation is simple and can stably seal the box body 4.
