[0028] An embodiment of the present application provides a lifting cart.

[0029] Reference Figure 1 and Figure 2 The lifting cart includes a frame 100 , a hydraulic module 200 , a telescopic rod 300 and a table 400 .

[0030] Among them, the hydraulic module 200 is arranged on the frame 100, and the hydraulic module 200 includes a hydraulic pump, an oil tank 230, a first oil pipe 210 and a second oil pipe 220, and the hydraulic pump is connected to the oil tank 230; the telescopic rod 300 is arranged on the frame 100, and the telescopic rod 300 includes a hollow rod body 301, a piston and a connecting rod 302, the piston is located in the hollow rod body 301, and the hollow rod body 301 is provided with a first through port 351 and a second through port 352, and the first through port 351 and the second through port 352 are respectively located on both sides of the piston, and the two ends of the first oil pipe 210 are respectively connected to the first through port 351 and the hydraulic pump, and the two ends of the second oil pipe 220 are respectively connected to the second through port 352 and the oil tank 230; the connecting rod 302 is passed through the hollow rod body 301, and the two ends of the connecting rod 302 are respectively connected to the table 400 and the piston.

[0031] In this embodiment, a heavy object, such as a server, is placed on the table 400. When the heavy object needs to be raised, the hydraulic pump operates, pumping hydraulic oil from the oil tank 230 and delivering it to the hollow rod body 301 from the first port 351 through the first oil pipe 210. As the hydraulic oil continues to enter the hollow rod body 301, the hydraulic oil pushes the piston upward, driving the connecting rod 302 connected to the piston and the table 400 connected to the connecting rod 302 upward, thereby raising the heavy object. When the heavy object needs to be lowered, the hydraulic oil in the hollow rod body 301 flows out from the second port 352 and flows back into the oil tank 230 through the second oil pipe 220. The piston moves downward under the action of gravity and external load, driving the connecting rod 302 connected to the piston and the table 400 connected to the connecting rod 302 downward, thereby lowering the heavy object.

[0032] The lifting trolley can provide stable and powerful lifting force. While carrying and transporting heavy objects, it can easily lift and lower heavy objects, greatly improving the convenience of operation.

[0033] It is understandable that the hollow rod body 301 forms a hydraulic cylinder, which cooperates with the hydraulic oil to control the movement of the piston.

[0034] The second oil pipe 220 is provided with an oil return valve. When the weight needs to be lowered, the oil return valve is adjusted to allow the hydraulic oil in the hollow rod body 301 to flow out of the second port 352 and back into the oil tank 230 through the second oil pipe 220. The piston moves downward under the action of gravity and external load, driving the connecting rod 302 connected to the piston and the table 400 connected to the connecting rod 302 downward, thereby lowering the weight.

[0035] The return valve is equipped with a knob and a flow control valve. The knob and the flow control valve are connected. The flow control valve is set in the channel of the return valve. Turning the knob adjusts the size of the flow control valve, which in turn controls the flow and pressure of the hydraulic oil, thereby adjusting the lifting speed and load capacity.

[0036] The frame 100 is rotatably connected to a handlebar 500. The user holds the handlebar 500 to push the lift cart, which is convenient for the user to push the lift cart.

[0037] The handlebar 500 is connected to the hydraulic pump via a horizontal jack assembly. One end of the handlebar 500 is mounted on a lever base 510. The lever base 510 allows the user to utilize the lever principle to swing the handlebar 500 to press the horizontal jack assembly, saving effort and improving ease of use.

[0038] The horizontal jack components can adopt the corresponding components in the T82251 horizontal jack.

[0039] With the aid of the horizontal jack assembly and lever base 510, the lifting and lowering motion of the lifting rod can be adjusted by swinging the handlebar 500. Closing the oil return valve on the second oil pipe 220 and then swinging the handlebar 500 up and down will cause the horizontal plate of the lever base 510 to drive the hydraulic pump piston to perform a reciprocating pumping motion. As hydraulic oil continuously enters the hollow rod body 301, it pushes the piston upward, driving the connecting rod 302 connected to the piston and the table 400 connected to the connecting rod 302 upward, thereby lifting the heavy object. Opening the oil return valve on the second oil pipe 220 allows the hydraulic oil in the hollow rod body 301 to flow out of the second port 352 and back into the oil tank 230 through the second oil pipe 220. The piston moves downward under the action of gravity and external load, driving the connecting rod 302 connected to the piston and the table 400 connected to the connecting rod 302 downward, thereby lowering the heavy object.

[0040] The frame 100 is provided with wheels 600. The wheels 600 are universal wheels. This makes it more convenient to transport heavy objects with the cart, saves the user's energy, and improves the convenience of use.

[0041] Reference Figure 3The hollow rod 301 includes a first rod 310, a second rod 320, a first reinforcing rod 330, and a second reinforcing rod 340. The first rod 310 and the second rod 320 are arranged in parallel. One side of the first rod 310 and the second rod 320 is connected by the first reinforcing rod 330, and the other side of the first rod 310 and the second rod 320 is connected by the second reinforcing rod 340. The first reinforcing rod 330 and the second reinforcing rod 340 play a reinforcing role, so that the hollow rod 301 can stably support the table 400 and the heavy objects on the table 400. The table 400 is rectangular. To match the rectangular table 400, the frame 100 is provided with two first rods 310 and two second rods 320, a total of four vertical rods, to support the rectangular table 400.

[0042] The two groups of first rods 310 and second rods 320 are correspondingly arranged. The corresponding two first rods 310 can be connected by a reinforcement strip, and the corresponding two second rods 320 can be connected by a reinforcement strip, which plays a role of further reinforcement.

[0043] A piston is provided in the channel of the first rod body 310, a piston is provided in the channel of the second rod body 320, the channel of the first reinforcement rod body 330 is connected to the channels of the first rod body 310 and the second rod body 320, the channel of the second reinforcement rod body 340 is connected to the channels of the first rod body 310 and the second rod body 320, the first reinforcement rod body 330 is provided with a first opening 351, and the second reinforcement rod body 340 is provided with a second opening 352.

[0044] When a heavy object needs to be lifted, the hydraulic pump operates, pumping hydraulic oil from the oil tank 230 and delivering it through the first oil pipe 210 and the first opening 351 to the first reinforcing rod 330. The hydraulic oil then flows along the channels of the first reinforcing rod 330 to both sides, entering the channels of the first rod 310 and the second rod 320. As the hydraulic oil continues to enter the hollow rod 301, it pushes the piston upward, driving the connecting rod 302 connected to the piston and the table 400 connected to the connecting rod 302 upward, thereby lifting the heavy object. When the heavy object needs to be lowered, the hydraulic oil in the channel of the first rod body 310 and the hydraulic oil in the channel of the second rod body 320 flow into the channel of the second reinforcing rod body 340, and flow out from the second opening 352 of the second reinforcing rod body 340, and return to the oil tank 230 through the second oil pipe 220. The piston moves downward under the action of gravity and external load, driving the connecting rod 302 connected to the piston and the table 400 connected to the connecting rod 302 to move downward, thereby lowering the heavy object.

[0045] The first reinforcing rod 330 is provided with a through hole 331 for the second oil pipe 220 to pass through. The second oil pipe 220 is connected to the second opening 352 of the second rod 320 after passing through the through hole 331. The through hole 331 plays a role in fixing the second oil pipe 220 and saves space.
