[0029] The following description, with reference to the accompanying drawings, depicts a high-strength load-bearing foam base according to an embodiment of this application.

[0030] like Figures 1-2 As shown in the embodiment of this application, a high-strength load-bearing foam base includes a packaging box 1 for packaging. Load-bearing base plates 2 are stacked from bottom to top inside the packaging box 1, and items 22 are securely placed between the upper and lower load-bearing base plates 2 via placement slots 21. Multiple sets of items 22 can then be fixed by the load-bearing base plates 2, allowing for stable transportation. Support blocks 26 for supporting intervals are provided at the four corners of the bottom surface of the load-bearing base plates 2, and a push-back component is also provided on the load-bearing base plates 2 to push back the spacing between adjacent load-bearing base plates 2.

[0031] First embodiment, such as Figures 3-7 As shown, the reverse thrust assembly consists of a lifting block 27 capable of telescopic displacement and a sliding block 24 capable of lateral sliding. Simultaneously, a sliding groove 23 is provided inward around the perimeter of the load-bearing base plate 2, allowing the sliding block 24 to slide laterally. The surface of the sliding groove 23 that contacts the sliding block 24 is set with an inclined structure. Therefore, when the load-bearing base plates 2 are stacked inside the packaging box 1, the sliding block 24 can slide laterally. At the same time, since the sliding groove 23 is set with an inclined structure, the surface of the sliding block 24 is moved away from the side wall of the packaging box 1, forming a certain gap, so that the side wall of the load-bearing base plate 2 will not be blocked by the side wall of the packaging box 1 after it is removed.

[0032] Meanwhile, a hand holding groove 322 is formed through the upper surface of the moving block 24 downward, and the supporting bottom plate 2 can be conveniently taken out from the packaging box 1 through the hand holding groove 322. Meanwhile, a sliding groove 231 is formed in the inner wall of the moving groove 23, and the sliding groove 231 can be in a T-shaped structure. Meanwhile, the sliding block on the surface of the moving block 24 can slide and displace along the inside of the sliding groove 231.

[0033] A belt 25 is arranged at the head and tail of the moving block 24, and a rotatable rotating block 28 is arranged at the inner wall of the belt 25. A gear 282 is arranged on the outer circumferential surface of the rotating block 28, and the gear 282 can be engaged with the belt 25. Therefore, after the moving block 24 is transversely displaced, the four groups of moving blocks 24 can be displaced through the belt 25. Meanwhile, the belt 25 can drive the rotating block 28 to rotate. A threaded hole 281 is formed upward on the bottom surface of the rotating block 28, and a threaded rod 271 is arranged inside the lifting block 27 and extends to the inside of the threaded hole 281. The lifting block 27 can be telescopically displaced through the lifting groove 261 formed through the bottom of the supporting block 26. The lifting groove 261 is preferably in a rectangular structure. When the supporting bottom plate 2 needs to be taken out from the inside of the packaging box 1, the moving block 24 can be transversely slid, and then a gap is formed between the side wall of the moving block 24 and the inner wall of the packaging box 1, so that the stacked supporting bottom plate 2 can be taken out. Meanwhile, when the moving block 24 is moved, the belt 25 arranged at one end of the moving block 24 can pull the rotating block 28 to rotate, and then the threaded rod 271 connected with the bottom of the rotating block 28 can be moved downward, so that the upper supporting bottom plate 2 can be pushed back through the lifting block 27, so that the placing groove 21 arranged at the bottom of the supporting bottom plate 2 can be separated from the placed object 22, and then the supporting bottom plate 2 can be taken out.

[0034] The second embodiment is shown as Figures 8-12 The opposite surfaces of the supporting bottom plate 2 are arranged with a turnover groove 3 downward, and a turnover block 31 is hingedly arranged in the turnover groove 3, so that the turnover block 31 can rotate around the rotating shaft 311 arranged at the two side ends of the turnover block 31. Meanwhile, the surface of the turnover block 31 is arranged with a moving groove two 33 in an inclined structure, and the moving block two 32 can slide and displace in the moving groove two 33. The upper surface of the moving block two 32 is arranged with a hand holding groove 322 downward, which can be held by hand.

[0035] One end of the rotating shaft 311 extends into the interior of the lifting groove 261, while a gear 312 is fixed to the other end of the rotating shaft 311. A rack 361, capable of meshing with the gear 312, is fixed to the top of the lifting block 36 inside the lifting groove 261. Therefore, when the load-bearing base plate 2 needs to be removed, the block 32 can be moved laterally, and then the flipping block 31 can be flipped upwards. The gears 312 at both ends of the flipping block 31 can then mesh with the rack 361, causing the four sets of lifting blocks 36 to extend from inside the lifting groove 261, allowing the lifting blocks 36 to push back and disengage.

[0036] The surface of the movable block 32 is provided with a limiting post 321, and one end of the limiting post 321 passes through the flip block 31. A transverse groove 34 is opened on the surface of the flip groove 3, and a rotating groove 35 is opened at the end of the transverse groove 34. The movable block 32 can be transversely limited by the limiting post 321, and the flip block 31 can be flipped.

[0037] like Figures 13-16 In the third embodiment, the same structure will not be described again. The movable slot 23 has a movable block 4 inside. An inclined groove 41 is formed on one end of the movable block 4, allowing the pressing block 43 to be pressed down. The pressing block 43 is located at the upper opening of the lifting slot 261. Inside the lifting slot 261, there is a retractable lifting block 42. A storage cavity 421 is located at the top of the lifting block 42, filled with expanding foam. A puncturable aluminum film 422 is provided at the top opening of the storage cavity 421, and a protrusion 44 that can puncture the aluminum film 422 is provided at the bottom of the pressing block 43. The top of the pressing block 43 has an arc-shaped structure. Therefore, when the horizontal sliding relative moving block 3 4 is moved, its inclined groove 41 will press down on the pressing block 43. Then the protrusion 44 at the bottom of the pressing block 43 can pierce the aluminum film 422. The foam inside the storage cavity 421 will then expand and solidify, and then push the lifting block 3 42 back to facilitate the placement groove 21 at the bottom of the load-bearing base plate 2 to be separated from the placed object 22, and then the load-bearing base plate 2 can be taken out.

[0038] The first embodiment is further improved, such as Figures 17-19When the first moving block 24 is moved horizontally to form a gap with the inner wall of the packaging box 1, and is pulled up, the load-bearing bottom plate 2 will also be tilted and pulled out, which will cause the load-bearing bottom plate 2 to be stuck. It is inconvenient to pull out. The bottom of the load-bearing bottom plate 2 is hinged with a rotatable swing rod 29, and the swing rod 29 is symmetrically arranged in two groups. One side of the upper end of one of the swing rods 29 is provided with a gear three 292, and a connecting rod 291 is hinged between the two swing rods 29. One side of the bottom of the first moving block 24 is provided with a rack one 241 which can engage with the gear three 292. When the first moving block 24 is moved horizontally, the rack one 241 can engage the transmission gear three 292, and then one of the swing rods 29 can be swung from a tilted state to a vertical state, and the two swing rods 29 can be straightened through the connecting rod 291. The end of the swing rod 29 is provided with a ball sleeve 293, and the inside of the ball sleeve 293 is also provided with a rolling ball 294. When the swing rod 29 is straightened, the rolling ball 294 can be attached to the inner wall of the packaging box 1, and when the load-bearing bottom plate 2 is pulled out from the inside of the packaging box 1, the rolling ball 294 can be rolled to facilitate the pulling out of the load-bearing bottom plate 2.

[0039] Specifically, the working principle of the high-strength load-bearing foam bottom support is as follows: in the first embodiment, when the load-bearing bottom plate 2 needs to be pulled out from the inside of the packaging box 1, the first moving block 24 can be moved horizontally, and then a gap is formed between the side wall of the first moving block 24 and the inner wall of the packaging box 1 to facilitate the pulling out of the stacked load-bearing bottom plate 2. At the same time, when the first moving block 24 moves, the belt 25 at one end of the first moving block 24 can pull the rotating block 28 to rotate, and then the threaded rod 271 connected to the bottom of the rotating block 28 can move downward, and the upper layer of the stacked load-bearing bottom plate 2 can be pushed back through the lifting block one 27 to facilitate the disengagement of the placing groove 21 at the bottom of the load-bearing bottom plate 2 from the placed object 22, and then the load-bearing bottom plate 2 can be pulled out. And when the first moving block 24 moves horizontally, the rack one 241 can engage the transmission gear three 292, and then one of the swing rods 29 can be swung from a tilted state to a vertical state, and the two swing rods 29 can be straightened through the connecting rod 291. Then, when the swing rod 29 is straightened, the rolling ball 294 can be attached to the inner wall of the packaging box 1, and when the load-bearing bottom plate 2 is pulled out from the inside of the packaging box 1, the rolling ball 294 can be rolled to facilitate the pulling out of the load-bearing bottom plate 2 In the second embodiment, when the load-bearing bottom plate 2 needs to be pulled out, the second moving block 32 can be moved horizontally, and then the flip block 31 can be flipped up, and the gear two 312 at both ends of the flip block 31 can engage the rack two 361, and then the four lifting blocks two 36 can be extended from the inside of the lifting groove 261 to form a pushback to disengage.

[0040] In the third embodiment, when the moving block three 4 slides horizontally, the inclined groove 41 presses the lower pressing block 43, and the protrusion 44 at the bottom of the lower pressing block 43 pierces the aluminum film 422, the foamed glue in the storage cavity 421 expands and solidifies, and then the lifting block three 42 is pushed upward, so that the placing groove 21 at the bottom of the load bearing bottom plate 2 can be separated from the placed object 22, and then the load bearing bottom plate 2 can be taken out.
