[0017] Reference Figures 1 to 6This utility model provides a cardboard box with an anti-compression structure, comprising a box body 1 and four bottom blocks 2. The four bottom blocks 2 are respectively disposed on the bottom inner walls of the four ends of the box body 1. Positioning rods 3 are fixedly installed on the upper surface of each of the four bottom blocks 2. Lifting cylinders 4 are sleeved on the outer surface of the positioning rods 3. Several sleeves 5 and sleeve rods 6 are provided on the inner walls of the four sides of the box body 1. The sleeve rods 6 are inserted into the sleeves 5. Connecting blocks 7 are fixedly installed on the ends of the sleeves 5 and sleeve rods 6 that are away from each other. The bottom blocks 2 and the lifting cylinders 4 are fixedly installed on the side walls away from the inner walls of the box body 1. A connecting sleeve 8 is fitted with a connecting block 7. A positioning block 9 is fixedly installed on the outer surface of the connecting block 7. A positioning groove 10 is opened through the outer wall of the connecting sleeve 8. The positioning groove 10 is L-shaped. The positioning block 9 is slidably connected to the inner wall of the positioning groove 10. The outer surfaces of the four sleeves 5 near the top of the lifting cylinder 4 are threaded with limit bolts 11. The limit bolts 11 penetrate the outer surface of the sleeves 5 and extend into the interior of the sleeves 5. The outer surfaces of the four corresponding sleeve rods 6 are provided with several limit holes that are inserted into the limit bolts 11.

[0018] In order to raise and lower the lifting cylinder 4, the top of each of the four positioning rods 3 is fixedly installed with a limit block 12, and the inner wall of each of the four lifting cylinders 4 is provided with a limit groove that matches the limit block 12. The top of one lifting cylinder 4 is threadedly connected with a lead screw 13, which passes through the upper surface of the lifting cylinder 4 and extends into the interior of the lifting cylinder 4. The top of each of the four corresponding positioning rods 3 is provided with a threaded hole that meshes with the lead screw 13, and a rotating block 14 is fixedly installed on the top of the lead screw 13.

[0019] By setting up a box body 1, a bottom block 2, a positioning rod 3, a lifting cylinder 4, a sleeve 5, a sleeve rod 6, a connecting block 7, a connecting sleeve 8, a positioning block 9, a positioning groove 10, a limiting bolt 11, a limiting block 12, a lead screw 13, and a rotating block 14, the function of resisting compression of the carton is realized. By using four sets of bottom blocks 2 and lifting cylinders 4 in cooperation with several sets of sleeves 5 and sleeve rods 6, the inner wall of the box body 1 is supported to prevent the carton from deforming and ensure the normal use of the carton. At the same time, it prevents the carton from tipping over and avoids damage to the carton and the objects inside the carton, thereby improving the practicality and service life of the carton. At the same time, the anti-compression structure can be adjusted according to the size of the box body 1, so that the anti-compression structure can be applied to cartons of different specifications.

[0020] Each of the four base blocks 2 has a fixing component at its bottom end. The fixing component includes a fixing plate 15, which is fixedly installed at the bottom end of the base block 2. A positioning plate 16 is provided on the lower surface of the fixing plate 15. A screw 17 is fixedly installed on the upper surface of the positioning plate 16. A nut 18 is threadedly connected to the outer surface of the top end of the screw 17. All four screws 17 pass through the lower surface of the corresponding fixing plate 15. The four nuts 18 abut against the upper surface of the corresponding fixing plate 15. Adhesive 19 is fixedly installed on the lower surface of the positioning plate 16.

[0021] By setting up a fixing plate 15, a positioning plate 16, a screw 17, a nut 18, and adhesive 19, the bottom block 2 is positioned and fixed. The positioning plate 16 is positioned and fixed by using adhesive 19, and the fixing plate 15 is fixed by using screw 17 and nut 18, thereby positioning and fixing the bottom block 2. The process is convenient and quick, saving time and effort, and improving the convenience of the cardboard box's compression-resistant structure.

[0022] Working principle: When resisting compression of the carton, firstly, the four positioning plates 16 are fixed to the bottom walls of the four ends of the carton body 1 with adhesive 19. Then, the four sets of bottom blocks 2 and the lifting cylinder 4 are brought close to the corresponding positioning plates 16, so that the four screws 17 pass through the corresponding fixing plates 15. Then, the four nuts 18 are screwed onto the corresponding screws 17, and the four nuts 18 are abutted against the upper surface of the corresponding fixing plates 15 to fix the four fixing plates 15, thereby fixing the four bottom blocks 2.

[0023] Next, the corresponding sleeves 5 and rods 6 are brought close to the inner walls of the housing 1, and all sleeves 5 and rods 6 are stretched so that the connecting blocks 7 of sleeves 5 and rods 6 slide into the interior of the connecting sleeves 8, and the positioning blocks 9 slide into the interior of the positioning grooves 10. Then, the sleeves 5 and rods 6 are rotated so that the positioning blocks 9 rotate to the bottom of the positioning grooves 10, so that the sleeves 5 and rods 6 are connected to the bottom block 2 and the lifting cylinder 4 through the connecting blocks 7 and the connecting sleeves 8. Then, the four limiting bolts 11 are tightened so that the four limiting bolts 11 pass through the corresponding sleeves 5 and are inserted into the limiting holes on the corresponding rods 6, thereby fixing the sleeves 5 and rods 6, thus supporting and resisting compression of the inner walls of the housing 1.

[0024] Next, rotate the rotating block 14, which drives the lead screw 13 to rotate. When the lead screw 13 rotates, with the bottom block 2 and the positioning rod 3 fixed, the lead screw 13 moves up and down through the threaded hole, thereby driving the lifting cylinder 4 to move up and down. Under the action of the sleeve 5 and the sleeve rod 6, the four lifting cylinders 4 move up and down simultaneously. When the four lifting cylinders 4 have reached the appropriate position, stop rotating the rotating block 14 to fix the position of the lifting cylinders 4, thus completing the support and anti-compression of the carton.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
