[0022] like Figures 1 to 5 As shown, the utility model provides a wear-resistant printed carton with high strength, including a hard carton 1, the upper side of the outer surface of the hard carton 1 is movably connected with a hard box cover 2, the front and rear sides of the lower surface of the hard box cover 2 are fixedly connected with a No. 1 connecting block 3, the number of No. 1 connecting blocks 3 is two, the outer surfaces of the two No. 1 connecting blocks 3 are movably connected with a No. 2 connecting block 4, the No. 2 connecting block 4 is fixedly connected to the outer surface of the hard carton 1, the inner surfaces of the left and right sides of the No. 2 connecting block 4 are movably connected with spring blocks 5, the outer surface of the spring block 5 and the inner surface of the No. 1 connecting block 3 are movably connected, the inner surface of the spring block 5 is fixedly connected to a No. 1 spring 6, and the other end of the No. 1 spring 6 is fixedly connected to the inner surface of the No. 1 connecting block 3.

[0023] Due to the external design of the No. 2 connecting block 4 and the spring block 5, when the hard case cover 2 and the No. 1 connecting block 3 are subjected to a large upward pulling force as a whole, the spring block 5 will retract into the interior of the No. 1 connecting block 3 under the squeezing of the No. 2 connecting block 4, thereby releasing the spring block 5 from fixing the hard case cover 2 and the No. 1 connecting block 3 as a whole.

[0024] The inner surface of the hard carton 1 is fixedly connected with wax paper 8 , and the top of the inner surface of the hard box cover 2 is fixedly connected with a sponge board 17 .

[0025] The design of the wax paper 8 can prevent external moisture from entering the interior of the hard carton 1, while the sponge board 17 has a certain elasticity and can be compressed under the pressure of external force.

[0026] Among them, the outer surfaces on both sides of the hard box cover 2 are provided with hand-pull grooves 7, the number of the hand-pull grooves 7 is two, and the positions of the two hand-pull grooves 7 are symmetrical about the hard carton 1.

[0027] The design of the hand-pull groove 7 makes it easy for the operator to pull the hard case cover 2 as a whole.

[0028] Among them, the outer surfaces of the front and rear sides of the hard cardboard box 1 are movably connected with triangular blocks 10, the lower surface of the triangular block 10 is fixedly connected with a grinding block 11, and the outer surfaces of the front and rear sides of the hard cardboard box 1 are fixedly connected with round blocks 9, the outer end of the round block 9 passes through the triangular block 10 and extends to the outside of the triangular block 10, and the outer surface of the round block 9 and the inner surface of the triangular block 10 are movably connected.

[0029] The design of the round block 9 and the triangular block 10 allows the operator to remove the triangular block 10 from the outer surface of the round block 9 .

[0030] Among them, the outer surface of the round block 9 is movably connected to the baffles 12 located on the front and rear sides of the triangular block 10, and the outer surface of the baffle 12 is fixedly connected to the movable block 13, and the movable block 13 is movably connected to the outer surface of the hard carton 1.

[0031] When the baffle 12 and the movable block 13 move so that the baffle 12 is out of contact with the outer surface of the triangular block 10 , the fixation of the entire triangular block 10 will be released.

[0032] Among them, the outer surfaces of the front and rear sides of the rigid carton 1 are fixedly connected with a fixed plate 15, the outer surface of the fixed plate 15 is fixedly connected with a limiting rod 14, the other end of the limiting rod 14 passes through the movable block 13 and extends to the outside of the movable block 13, and the outer surface of the limiting rod 14 and the inner surface of the movable block 13 are movably connected.

[0033] The design of the limiting rod 14 serves to limit the movable block 13 .

[0034] The outer surface of the fixed plate 15 is fixedly connected to a No. 2 spring 16 , and the other end of the No. 2 spring 16 is fixedly connected to the outer surface of the movable block 13 .

[0035] The design of the No. 2 spring 16 allows the baffle 12 to resume contact with the round block 9 under the elastic force of the No. 2 spring 16 .

[0036] The working principle and use process of this utility model:

[0037] When the grinding block 11 is excessively worn, the operator pulls the movable block 13, so that the movable block 13 and the baffle 12 begin to move toward the fixed plate 15. When the baffle 12 no longer contacts the outer surface of the triangular block 10, the fixation of the triangular block 10 as a whole from the round block 9 and the baffle 12 will be released. At this time, the operator can directly remove the triangular block 10 as a whole for replacement, thereby ensuring the wear resistance of the hard carton 1 as a whole during subsequent use.

[0038] When the operator needs to seal the goods inside the hard carton 1, the operator first puts the hard box cover 2 and the No. 1 connecting block 3 on the outer surface of the hard carton 1, and aligns the outer surface of the No. 1 connecting block 3 with the inner surface of the No. 2 connecting block 4. Then the operator presses the hard box cover 2 downward as a whole. As the hard box cover 2 and the No. 1 connecting block 3 move, the spring block 5 will be squeezed by the outer surface of the No. 2 connecting block 4 and shrink into the interior of the No. 1 connecting block 3. When the lower surface of the No. 1 connecting block 3 and the No. 2 connecting block 4 are aligned, the spring block 5 will shrink into the interior of the No. 1 connecting block 3. When the No. 1 connecting block 4 comes into contact, the spring block 5 will come into contact with the inner surface of the No. 2 connecting block 4 due to the elastic force of the No. 1 spring 6. At this time, the hard box cover 2 and the No. 1 connecting block 3 will be fixed on the top of the hard carton 1 by the spring block 5 as a whole. Then the operator releases the hard box cover 2. At this time, the sponge board 17 begins to recover to its original shape because it is no longer squeezed by external force, which makes the gap between the hard carton 1 and the hard box cover 2 filled with the sponge board 17, thereby achieving the sealing of the goods inside the hard carton 1.
