DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following is a further detailed description of the present application with reference to the Figures 1-5 drawings.

[0021] The embodiment of the present application discloses a compression-resistant packaging carton. Refer to Figure 1, including a placement rack 1 on which a carton body 2 can be placed. The inner wall of the placement rack 1 is slidably connected to the carton body 2. A plurality of support rods 3 are closely attached to the inner walls of the carton body 2, which can be attached to the four corners of the inner wall of the carton body 2 to facilitate improving the compressive resistance of the carton body 2. Two outer shell rods 4 are fixedly connected to the outer walls of the plurality of support rods 3. An inner shell rod 5 is slidably connected to the inner wall of the outer shell rod 4. A connecting shell 6 is fixedly connected to the outer wall of the outer shell rod 4. Two clamping plates 7 are fixedly connected to the inner walls of the connecting shell 6. An insertion rod 8 is slidably connected to the body of the clamping plate 7, which can fix the outer walls of the outer shell rod 4 and the inner shell rod 5. A circular ring plate 9 is fixedly connected to the rod body of the insertion rod 8. Springs 10 are fixedly connected to the bodies of the two clamping plates 7. When passing through the circular ring plate 9, the springs 10 can push the insertion rod 8 into the inside of the slot. The other end of the spring 10 is fixedly connected to the circular ring plate 9. Two winding wheels 11 are rotatably connected to the inner walls of the two connecting shells 6. A rotating sleeve is provided on one side to facilitate rotating the winding wheels 11. Two pull ropes 12 are fixedly connected to the outer walls of the winding wheels 11, which can pull the insertion rod 8 so that the insertion rod 8 can be disengaged from the inside of the slot. The other end of the pull rope 12 is fixedly connected to the insertion rod 8. Two pushing components are provided on the inner walls of the carton body 2.

[0022] Specifically, referring to Figure 5 , the pushing component includes a central shell 13, a first sliding rod 14, a first sliding sleeve 15, a second sliding rod 17, a second sliding sleeve 18, and a rotating support rod 19. The inner walls of the carton body 2 are closely attached to the two central shells 13. The inner wall of the central shell 13 is fixedly connected to the first sliding rod 14. The rod bodies of the first sliding rod 14 are slidably connected to the two first sliding sleeves 15. The inner walls of the plurality of support rods 3 are fixedly connected to the second sliding rod 17. The rod bodies of the second sliding rod 17 are slidably connected to the two second sliding sleeves 18. Both sides of the rotating support rod 19 are hingedly connected to the plurality of first sliding sleeves 15 and the second sliding sleeves 18. The rotating support rod 19 is arranged in an X shape and is rotatably connected to each other in the middle. When the rotating support rod 19 rotates, it can drive the first sliding sleeve 15 and the second sliding sleeve 18 to slide on the rod bodies of the first sliding rod 14 and the second sliding rod 17 respectively, facilitating pushing the support rods 3 to fit at the four corners of the inner wall of the carton body 2.

[0023] Referring to Figure 2 , two baffle plates 21 are clamped and connected to the upper ends of the placement rack 1. A square frame 20 is clamped and connected to the upper ends of the placement rack 1 and the baffle plates 21. The fixing effect of the placement rack 1 on the carton body 2 can be improved through the baffle plates 21 and the square frame 20.

[0024] Referring to Figure 3 , a plurality of slots are opened on the rod bodies of the outer shell rod 4 and the inner shell rod 5. The plurality of insertion rods 8 are clamped and connected to the slots, which can insert the insertion rods 8 into the inside of the slots to facilitate fixing the positions of the outer shell rod 4 and the inner shell rod 5 and facilitating fitting the support rods 3 to the inner wall of the carton.

[0025] Referring to Figure 5, a plurality of screw grooves are formed in the outer walls of the central housing 13. The inner walls of the screw grooves are rotationally connected to the screw rods 16 through threads. One side of the screw rod 16 is rotationally connected to the first sliding sleeve 15 through threads. The screw rod 16 can be rotated into the interior of the first sliding sleeve 15 through the screw groove, facilitating the fixation of the first sliding sleeve 15 on the rod body of the first sliding rod 14, thereby preventing the rotating support rod 19 from rotating.

[0026] The implementation principle of an anti-pressure packaging carton according to an embodiment of the present application is as follows: During use, the carton body 2 can be placed inside the placement rack 1. By splicing the baffle 21 on the surface of the placement rack 1, it is convenient to splice the square frame 20 on the surfaces of the placement rack 1 and the baffle 21. Then, a plurality of support rods 3 are placed inside the carton body 2. By rotating the rotating sleeve on one side of the rope winding wheel 11, the pull rope 12 can pull the insertion rod 8. By moving the outer housing rod 4 and the inner housing rod 5, the support rods 3 on both sides can be attached to the surface of the carton body 2. At the same time, under the action of the spring 10, the insertion rod 8 can be pushed through the circular ring piece 9, so that the insertion rod 8 is inserted into the slot inside the surfaces of the outer housing rod 4 and the inner housing rod 5, facilitating the fixation of the position of one side of the support rod 3. At the same time, rotate the rotating support rod 19, so that the rotating support rod 19 can drive the first sliding sleeve 15 and the second sliding sleeve 18 to slide on the rod bodies of the first sliding rod 14 and the second sliding rod 17 respectively, facilitating the support rod 3 to be pushed against the four corners of the inner wall of the carton body 2. And by rotating the screw rod 16 into the screw grooves inside the central housing 13 and the first sliding sleeve 15, the position of the first sliding sleeve 15 on the surface of the first sliding rod 14 is fixed, facilitating the improvement of the anti-pressure performance of the carton body 2.
