[0020] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown: A double-opening folding storage toolbox includes a toolbox structure 1, which includes a bottom box 10, two sets of middle folding boxes 13 and two sets of long folding boxes 15, and also includes a placement structure 2. The lower end of the placement structure 2 is provided with a support structure 4, and the upper end of the toolbox structure 1 is provided with a shielding structure 5. The placement structure 2 includes a first flip plate 20, two sets of limiting plate bodies 21, and a second flip plate 23. A first adapter 22 is fixedly installed at the lower end of the second flip plate 23, located at both side edges. A second adapter 221 is fixedly installed at the lower end of the first flip plate 20. A limiting protruding strip 24 is fixedly installed at one end of each of the two sets of limiting plate bodies 21. A guide telescopic rod 25 is fixedly installed at one end of each of the two sets of limiting plate bodies 21, near both side edges. A mating groove 26 is formed at one end of both the first flip plate 20 and the second flip plate 23, near both side edges. Tensile elastic elements 27 are fixedly installed on the inner sidewalls of the four sets of mating grooves 26. The two sets of first adapters 22 and... The adapter 221 has a mounting shaft 29 inserted inside. Both ends of the mounting shaft 29 are threaded with limit nuts 28. The flip plate 1 20 and the flip plate 23 are located directly above the bottom box 10. The lower parts of the two sets of limit plates 21 are respectively set inside the two sets of long folding boxes 15. The lower ends of the two sets of limit protrusions 24 are respectively in contact with the upper ends of the long folding boxes 15. The other ends of the four sets of guide telescopic rods 25 are respectively inserted into the four sets of mating grooves 26. The other ends of the four sets of tension elastic elements 27 are respectively fixed to one end of the two sets of limit plates 21, and the four sets of tension elastic elements 27 are respectively sleeved on the outer wall of the four sets of guide telescopic rods 25. Lower short folding arms 11 are rotatably installed on both sides of the bottom box 10 and near the edges of both sides. Two sets of long folding arms 12 are rotatably installed on both sides of the bottom box 10. Upper short folding arms 14 are rotatably installed on both sides of the two sets of middle folding boxes 13 and near the edges of both sides. The other four protruding parts of the four sets of lower short folding arms 11 are rotatably installed on both sides of the two sets of middle folding boxes 13. The other four protruding parts of the four sets of long folding arms 12 are rotatably installed on both sides of the long folding box 15. The other four protruding parts of the four sets of upper short folding arms 14 are rotatably installed on both sides of the long folding box 15. The lower ends of the two sets of long folding boxes 15 are in contact with the upper ends of the two sets of middle folding boxes 13. The lower ends of the two sets of middle folding boxes 13 are in contact with the upper ends of the bottom box 10.

[0021] In this embodiment, the first flip plate 20 and the second flip plate 23 are first flipped open, so that one end of them contacts each other. The first flip plate 20 and the second flip plate 23 respectively drive the second adapter 221 and the first adapter 22 to move, so that the second adapter 221 and the first adapter 22 rotate on the outer wall of the mounting shaft rod 29. Then, the two sets of limiting plate bodies 21 are stretched to move to both ends. During this process, the two sets of limiting plate bodies 21 respectively drive the two sets of tension elastic members 27 to pull, so that the four sets of tension elastic members 27 extend outward inside the four sets of mating circular grooves 26. At the same time, they also drive the four sets of guide telescopic rods 25 to move in the four sets of mating circular grooves 26. The internal sliding mechanism allows the two sets of limiting plates 21 to be snapped into the inside of the two sets of long folding boxes 15, until the two sets of limiting protruding plates 24 are attached to the upper ends of the two sets of long folding boxes 15. With the cooperation of the four sets of guide telescopic rods 25 and the two sets of limiting protruding plates 24, the flip plate 1 20 and the flip plate 23 can be supported. In this way, a temporary workbench can be obtained for convenient work. This allows the toolbox to not only serve the function of storage, but also eliminates the need for an additional workbench to temporarily place tools or equipment during work operations, making the toolbox convenient to use. When storing and carrying, the two sets of limiting nuts 28 are screwed down to screw down from the outer wall of the mounting shaft rod 29. Then the mounting shaft rod 29 is pulled out and moved out from the inside of the adapter seat 1 22 and adapter seat 221. Then the flip plate 1 20 and flip plate 23 are stacked together and placed in the bottom box 10 for storage and use, making it more convenient to carry. When the two sets of limiting plate bodies 21 move, the two sets of limiting plate bodies 21 drive the two sets of guide telescopic rods 25 to move, so that the four sets of guide telescopic rods 25 slide inside the four sets of mating circular grooves 26 respectively, thus increasing the stability of the flip plate one 20 and the flip plate two 23. By opening the two sets of middle folding boxes 13 to both ends, the two sets of middle folding boxes 13 will drive the four sets of lower short folding rotating arms 11 to move. The two protruding parts of the four sets of lower short folding rotating arms 11 will rotate on the two sides of the bottom box 10 and the two outer walls of the two sets of middle folding boxes 13 respectively. By opening the two sets of long folding boxes 15 to both ends, the two sets of long folding boxes 15 will drive the four sets of long folding rotating arms 12 and the four sets of upper short folding rotating arms 14 to move. This will cause the eight protruding parts of the four sets of long folding rotating arms 12 to rotate on the two side walls of the bottom box 10 and the two side walls of the two sets of long folding boxes 15 respectively. The eight protruding parts of the four sets of upper short folding rotating arms 14 will rotate on the two outer walls of the two sets of middle folding boxes 13 and the two outer walls of the two sets of long folding boxes 15 respectively. Thus, the storage toolbox can be opened for convenient use later.

[0022] Example 2: According to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the support structure 4 includes three sets of diagonal bracing cylinders 41 and a connecting seat 43. Each of the three sets of diagonal bracing cylinders 41 has a threaded diagonal rod 42 internally connected. A pressing seat 44 is provided below the connecting seat 43. A detachable limiting seat 46 is installed at the upper end of the connecting seat 43. A telescopic support block 47 is installed inside the detachable limiting seat 46. A fixing head 48 is installed at the upper end of the telescopic support block 47 and at both side edges. Support components 45 are fixedly installed at the upper ends of both sets of fixing heads 48. The three sets of diagonal bracing cylinders 41... All three sets of mating seats 49 are fixedly installed on the outer wall. Movable support rods 410 are rotatably installed inside the grooves of the three sets of mating seats 49. The upper parts of the three sets of inclined support cylinders 41 are rotatably installed inside the three grooves on the outer wall of the connecting seat 43. The other ends of the three sets of movable support rods 410 are rotatably installed inside the three grooves on the outer wall of the pressing seat 44. The lower ends of the three sets of threaded inclined rods 42 are in contact with the inner bottom of the bottom box 10. The upper ends of the two sets of support components 45 are in contact with the lower ends of the flip plate 1 20 and the flip plate 2 23, respectively.

[0023] In this embodiment, by turning the three sets of threaded inclined rods 42 one by one, the three sets of threaded inclined rods 42 rotate inside the inclined support cylinder 41, allowing the three sets of threaded inclined rods 42 to move downwards or upwards, thus extending the length of the three sets of inclined support cylinders 41. Then, by pushing the pressing seat 44 downwards, the pressing seat 44 pushes the three sets of movable support rods 410 downwards together, causing the three sets of movable support rods 410 to move away from the three sets of inclined support cylinders 41. During this process, one end of each of the three sets of movable support rods 410 moves inside the three grooves on the outer wall of the pressing seat 44, and the other end of each of the three sets of movable support rods 410 moves inside the three sets of mating seats 49, thus pushing the three sets of inclined support cylinders 41 outwards. At the same time, the upper parts of the three sets of inclined support cylinders 41 move inside the connecting seat 43, and the three sets of inclined support cylinders 41 also drive the three sets of threaded rods 41. The diagonal rod 42 is moved to unfold three sets of diagonal bracing cylinders 41. Then, the detachable limiting seat 46 is installed on the upper end of the connecting seat 43, and the telescopic support block 47 is installed inside the detachable limiting seat 46. Then, two sets of support components 45 are installed on both ends of the telescopic support block 47. The support structure 4 is placed inside the bottom box 10, and the bottom ends of the three sets of threaded diagonal rods 42 are in contact with the bottom end of the bottom box 10. Then, the lower ends of the flip plate 1 20 and the flip plate 2 23 are respectively in contact with the upper ends of the two sets of support components 45, thereby supporting the flip plate 1 20 and the flip plate 2 23, thus supporting the placement structure 2 and providing a certain load-bearing support effect, improving the firmness and stability of the placement structure 2, and making the toolbox more stable overall.

[0024] Example 3: According to Figure 1 and Figure 8As shown, the shielding structure 5 includes a first cover plate 51 and a second cover plate 52. A handle adapter 6 is fixedly installed at one end of each of the two sets of long folding boxes 15, near the edges on both sides. A shaped adapter block 7 is rotatably installed inside each of the four handle adapter seats 6. The supporting handle structure 3 includes two sets of anti-slip handle rods 30. A damping shaft 32 is fixedly installed on both sides of each of the two sets of long folding boxes 15. A handle rotating arm 31 is rotatably installed on one side of each of the four sets of damping shafts 32. The four handle rotating arms 31 are respectively fixed to the sides of the two sets of anti-slip handle rods 30. One end of each of the four shaped adapter blocks 7 is fixed to one end of the first cover plate 51 and the second cover plate 52. A round hole buckle 8 is fixedly installed at one end of both the first cover plate 51 and the second cover plate 52, and the two sets of round hole buckles 8 are in contact with each other. The lower ends of the first cover plate 51 and the second cover plate 52 are respectively located at the upper ends of the two sets of long folding boxes 15.

[0025] In this embodiment, with the cooperation of cover plate 1 51 and cover plate 2 52, cover plate 1 51 and cover plate 2 52 respectively cover the upper ends of the two sets of long folding boxes 15, thereby achieving a sealing effect. The two sets of round hole buckles 8 are designed so that after cover plate 1 51 and cover plate 2 52 are flipped inward to close, the lock head can be inserted through the through hole in the two sets of round hole buckles 8 to lock them, which is convenient for limiting cover plate 1 51 and cover plate 2 52 and making it more convenient to use. With the cooperation of four sets of handle adapter seats 6 and four sets of irregularly shaped adapter blocks 7, by flipping the cover plate 1 51 and cover plate 2 52 one by one, cover plate 1 51 will drive two sets of irregularly shaped adapter blocks 7 to rotate inside the two sets of handle adapter seats 6, while cover plate 2 52 will drive the other two sets of irregularly shaped adapter blocks 7 to rotate inside the other two sets of handle adapter seats 6, thereby flipping cover plate 1 51 and cover plate 2 52, so that the two sets of long folding boxes 15 can be exposed. By rotating the two sets of anti-slip handles 30 one by one, the two sets of anti-slip handles 30 will drive the four sets of handle rotating arms 31 to move. The protrusions of the four sets of handle rotating arms 31 will rotate inside the four sets of damping rotating shafts 32 respectively, until the two sets of anti-slip handles 30 are pressed against the ground below, which can play a certain role in bearing the load and supporting the force, thereby making the overall structure of the toolbox 1 more stable. In addition, after the two sets of anti-slip handles 30 are folded up and the two sets of anti-slip handles 30 are in contact, it is convenient for the user to lift the storage toolbox, improving the convenience of storing the toolbox.

[0026] The usage method and working principle of this device are as follows: First, when using it, unfold the two sets of medium folding boxes 13 and the two sets of long folding boxes 15 outwards respectively, and then flip the cover plate 1 51 and the cover plate 2 52 over so that they are separated from the two sets of long folding boxes 15 respectively. Then, each of the three sets of threaded inclined rods 42 is turned individually, causing them to rotate within the threads of the inclined support cylinders 41. This allows the three sets of threaded inclined rods 42 to move downwards or upwards, extending the length of the three sets of inclined support cylinders 41. Then, by pushing the pressing seat 44 downwards, the pressing seat 44 pushes the three sets of movable support rods 410 downwards together, causing them to move away from the three sets of inclined support cylinders 41. During this process, one end of each of the three sets of movable support rods 410 moves within one of the three grooves on the outer wall of the pressing seat 44, while the other end moves within one of the three sets of mating seats 49, pushing the three sets of inclined support cylinders 41 outwards. Meanwhile, the upper parts of the three sets of inclined support cylinders 41 move inside the connecting seat 43. The three sets of inclined support cylinders 41 also drive the three sets of threaded inclined rods 42 to move. The three sets of inclined support cylinders 41 can be unfolded. Then, the detachable limiting seat 46 is installed on the upper end of the connecting seat 43, and the telescopic support block 47 is installed inside the detachable limiting seat 46. Then, the two sets of support components 45 are installed on both ends of the telescopic support block 47. The support structure 4 is placed inside the bottom box 10, and the bottom ends of the three sets of threaded inclined rods 42 are in contact with the bottom end of the bottom box 10. Then, the lower ends of the flip plate 1 20 and the flip plate 2 23 are in contact with the upper ends of the two sets of support components 45 respectively. Finally, flip open flip plate 1 20 and flip plate 23 so that one end of them contacts each other. Flip plate 1 20 and flip plate 23 respectively drive adapter 2 221 and adapter 1 22 to move, so that adapter 2 221 and adapter 1 22 rotate on the outer wall of the mounting shaft rod 29. Then, stretch the two sets of limiting plate bodies 21 to move to both ends. During this process, the two sets of limiting plate bodies 21 respectively drive and pull the two sets of tension elastic elements 27, so that the four sets of tension elastic elements 27 respectively move into the four sets of mating circular grooves 26. The inside extends outward, and at the same time, it will drive the four sets of guide telescopic rods 25 to slide inside the four sets of mating circular grooves 26 respectively. Then, the two sets of limiting plate bodies 21 are respectively snapped into the inside of the two sets of long folding boxes 15 until the two sets of limiting convex plates 24 are respectively attached to the upper end of the two sets of long folding boxes 15. With the cooperation of the four sets of guide telescopic rods 25 and the two sets of limiting convex plates 24, the flip plate one 20 and the flip plate two 23 can be supported. In this way, a temporary workbench can be obtained for convenient work.
