[0024] The technical solutions provided by the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5As shown, the foldable forklift of this embodiment includes a base 1, a connecting assembly 2, a connecting frame 3, wheels 4, a drive assembly 6, a lifting assembly 7, and a support base rod 8. The two ends of the base 1 are respectively fixedly connected to the connecting assemblies 2. The two connecting assemblies 2 are rotatably connected to one end of the support base rod 8. The other end of the support base rod 8 is fixedly connected to a mounting seat 81. The mounting seat 81 is equipped with a support wheel 82. Specifically, the connecting assembly 2 includes a connecting seat 21, a first connecting seat 22, a second connecting end 76, and a hinge shaft 24. The end of the connecting seat 21 away from the lifting plate 71 is symmetrically fixedly connected to the first connecting seat 22. One end of the support base rod 8 is rotatably connected to the two first connecting seats 22 through the hinge shaft 24. The end of the connecting seat 21 near the lifting plate 71 is symmetrically fixedly connected to the second connecting seat 23. The two second connecting seats 23 are respectively provided with first fixing screw holes 25. The support base rod 8 is symmetrically provided with mating bolt holes on both sides. When goods need to be moved, rotate the support base 8 to a horizontal position. At this time, the mating bolt hole of the support base 8 corresponds to the first fixing bolt hole 25 of the second connecting seat 23. The support base 8 and the second connecting seat 23 can then be connected by fixing bolts. After use, when the forklift needs to be folded, first remove the fixing bolts and rotate the support base 8 clockwise around the hinge axis 24 until the mating bolt hole of the support base 8 corresponds to the second fixing bolt hole 32 on the connecting frame 3. The support base 8 and the connecting frame 3 can then be connected by fixing bolts, realizing the folding of the support base 8, which can effectively save space and is convenient to carry.

[0026] In this design, two connecting components 2 are fixedly connected to connecting brackets 3 on opposite sides. The wheel 4 is detachably installed in the wheel 4 mounting hole 31 of the connecting bracket 3. By providing a detachable wheel 4, space can be further saved. Since the wheel 4 is detachably installed in the wheel 4 mounting hole 31 of the connecting bracket 3, when the wheel 4 is worn, damaged, or needs to be replaced, it can be easily removed from the connecting bracket 3 and a new wheel 4 can be installed. This simplifies the wheel 4 replacement process, reduces maintenance costs, and improves maintenance efficiency.

[0027] Specifically, the upper parts of the two connecting components 2 are respectively fixedly connected to a first fixing rod 13 and a second fixing rod 14. The top of the first fixing rod 13 and the second fixing rod 14 are respectively provided with handles. By providing handles, the movement of the forklift can be facilitated. In order to improve the stability of the connection between the first fixing rod 13 and the second fixing rod 14, a connecting rod 15 is fixedly connected between the upper parts of the first fixing rod 13 and the second fixing rod 14. Furthermore, a handle cover 16 is provided on the handle at the top of the first fixing rod 13 and the second fixing rod 14, and the outer surface of the handle cover 16 is provided with an anti-slip pattern.

[0028] In this embodiment, the lifting assembly 7 includes a lifting plate 71, side connecting plates 72, a rotating shaft 73, a first fork 75, and a second fork 77. The lifting plate 71 has side connecting plates 72 fixedly connected to both ends, and a rotating shaft 73 connects the two side connecting plates 72. The rotating shaft 73 is located on the side of the lifting plate 71 away from the drive assembly 6. A first connecting end 74 and a second connecting end 76 are rotatably connected to the rotating shaft 73. The first fork 75 is fixedly connected to the first connecting end 74, and the second fork 77 is fixedly connected to the second connecting end 76. The drive assembly 6 can drive the lifting plate 71 to achieve lifting movement. Preferably, a connecting shaft 78 is connected to the opposite side of the two side connecting plates 72, and a guide wheel 79 is rotatably connected to the connecting shaft 78. The two guide wheels 79 are respectively connected to the first fixed rod 13 and the second fixed rod 14.

[0029] At this point, the lifting plate 71, as the main load-bearing component, has side connecting plates 72 fixedly connected to both ends, providing stable support for the rotating shaft 73 and other connecting components. The rotating shaft 73 is located on the side of the lifting plate 71 away from the drive assembly 6. By connecting the first connecting end 74 and the second connecting end 76, the first fork 75 and the second fork 77 are rotatably connected. The first fork 75 and the second fork 77 can rotate clockwise or counterclockwise around the rotating shaft 73. The first fork 75 and the second fork 77 are fixedly connected to the first connecting end 74 and the second connecting end 76, respectively, for carrying and transporting goods. The drive assembly 6 is responsible for driving the lifting plate 71 to achieve lifting and lowering movements, thereby driving the entire lifting assembly 7 and the goods to move vertically. Furthermore, the guide wheels 79 are connected to the first fixed rod 13 and the second fixed rod 14, respectively, to provide guidance and stability during the lifting process, preventing the lifting assembly 7 from shifting or shaking during the lifting process. This lifting assembly 7 has the advantages of stable structure, high flexibility, high lifting efficiency, convenient maintenance, and wide applicability, and can meet the needs of goods handling in different scenarios.

[0030] A placement plate 9 is fixedly connected between the first fixed rod 13 and the second fixed rod 14. The first fork 75 and the second fork 77 can be placed on the placement plate 9 after rotating around the rotation shaft 73, providing support points for the first fork 75 and the second fork 77 in their non-working state. When it is necessary to move goods, the first fork 75 and the second fork 77 will rotate clockwise around the rotation shaft 73. After rotating to the working position, the lifting plate 71 is lowered to the lowest end by the drive assembly 6, and then the fork tips of the first fork 75 and the second fork 77 are inserted into the bottom of the goods, ready for handling. After use, the lifting plate 71 is raised to a suitable position by the drive assembly 6, and then the first fork 75 and the second fork 77 rotate counterclockwise around the rotation shaft 73 and are placed on the placement plate 9, at which time they are in a non-working state. The placement plate 9 provides a stable support point for the forks. When not in operation, the forks can be smoothly placed on the placement plate 9, avoiding safety hazards caused by shaking or falling off, reducing the space occupied, and making the entire lifting assembly 7 more compact and neat.

[0031] Preferably, to facilitate the fixing of the first fork 75 and the second fork 77, fixing holes 771 are respectively provided at the bottom of the first fork 75 and the second fork 77. A mating block 11 is symmetrically fixed to the side of the base 1 away from the lifting plate 71, and the mating block 11 is engaged with the fixing hole 771. When it is necessary to fix the fork to the base 1, first rotate the fork around the rotating shaft 73 until it overlaps the placement plate 9, then align the mating block 11 with the fixing hole 771 at the bottom of the fork, and connect the mating block 11 to the fixing hole 771 by insertion, rotation, locking, or other means, thereby fixing the fork. Conversely, when it is necessary to release the fork, simply pull the mating block 11 out of the fixing hole 771 or unlock it. This ensures that the fork remains stable in the fixed state, preventing it from shaking or falling off, and improving the safety of the forklift during handling after folding.

[0032] Furthermore, the drive assembly 6 includes a drive cylinder 61, a drive rod 62, a drive sprocket 63, and a drive chain 64. A base plate 5 is fixedly connected to the middle of the base 1. The drive cylinder 61 is fixedly connected to the base plate 5 and a drive pedal 12 is detachably installed at the bottom. The output end of the drive cylinder 61 is vertically upward and connected to the drive rod 62. The two ends of the drive rod 62 are respectively connected to the drive sprocket 63. The drive chain 64 is connected to the drive sprocket 63. One end of the drive chain 64 is fixedly connected to the placement plate 9, and the other end is fixedly connected to the lifting plate 71. The drive cylinder 61 is started by driving the drive pedal 12. The output end of the drive cylinder 61 pushes the drive rod 62 to move up and down. The movement of the drive rod 62 drives the drive sprockets 63 at both ends to move up and down synchronously. When the drive sprockets 63 move up and down, they can drive the drive chain 64 to move accordingly. Since one end of the chain is fixedly connected to the placement plate 9 and the other end is fixedly connected to the lifting plate 71, the movement of the chain will drive the lifting plate 71 to move up and down relative to the placement plate 9. By controlling the extension and retraction of the drive cylinder 61, the lifting height of the lifting plate 71 can be precisely controlled.

[0033] In this embodiment of the foldable forklift, when in use, first install one wheel 4 on the connecting frame 3 on one side, then remove the fixing bolts between the supporting base rod 8 and the connecting frame 3 on that side, causing the supporting base rod 8 to rotate counterclockwise around the hinge axis 24, rotating the supporting base rod 8 to a horizontal state. At this time, the mating bolt holes of the supporting base rod 8 correspond to the positions of the first fixing screw holes 25 of the second connecting seat 23. The supporting base rod 8 and the second connecting seat 23 are then connected again using fixing bolts. Similarly, the same installation and opening operation is performed on the other side's wheel 4 and supporting base rod 8; then... Lift the forklift, then install the drive pedal 12 at the bottom of the drive cylinder 61. The drive pedal 12 drives the drive cylinder 61 to start. The output end of the drive cylinder 61 pushes the drive rod 62 to rise. The rise of the drive rod 62 causes the drive sprockets 63 at both ends to rise synchronously. When the drive sprockets 63 rise, they can drive the drive chain 64 to move accordingly. Since one end of the chain is fixedly connected to the placement plate 9 and the other end is fixedly connected to the lifting plate 71, the movement of the chain will cause the lifting plate 71 to rise relative to the placement plate 9. At this time, the first fork 75 and the second fork 77 are rotated around the rotating shaft 73... The clock hand rotates to the working position, and then the lifting plate 71 is lowered to its lowest point via the drive assembly 6. The tips of the first fork 75 and the second fork 77 are then inserted into the bottom of the goods, ready for transport. After transport, the lifting plate 71 is raised to a suitable position via the drive assembly 6, and the first fork 75 and the second fork 77 rotate counterclockwise around the rotation axis 73 and rest on the placement plate 9. At this point, they are in a non-working state. The mating block 11 of the base 1 is aligned with the fixing hole 771 at the bottom of the fork to secure it. The drive pedal 1 is then removed. 2. Then, detachably connect the drive pedal 12 to the forklift body, then lay the forklift down, remove the wheel 4 on one side of the forklift, and remove the fixing bolt between the support base rod 8 and the second connecting seat 23 on that side. Rotate the support base rod 8 clockwise around the hinge axis 24 until the mating bolt hole of the support base rod 8 corresponds to the position of the second fixing bolt hole 32 on the connecting frame 3. The support base rod 8 and the connecting frame 3 can then be connected by fixing bolts to achieve the folding of the support base rod 8. Similarly, perform the same folding and disassembly operation on the wheel 4 and the support base rod 8 on the other side.

[0034] The foldable forklift of this utility model, by setting up a connecting component, a connecting frame, a drive component, a lifting component and a support base 8, can realize the folding of the support base 8 and the forks, so that the forklift can be folded up when not in use, which greatly saves storage space. The folded size is small and easy to carry, which improves the flexibility of logistics transportation. The overall structure of this utility model is compact, easy to use and highly practical.

[0035] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
