[0002] With the development of Chinese society and the increase in the number of cars, car maintenance is very common. When repairing a car, it is necessary to repair the bottom of the car. However, the current car lifts can only lift the car vertically, but cannot tilt the car, which is inconvenient for local maintenance and affects the maintenance efficiency. Moreover, during the maintenance process, the car body cannot be moved, rotated, tilted, etc. in position and orientation, which increases the difficulty of workers in maintenance operations and greatly reduces work efficiency.
[0003] The existing patent (Announcement No.: CN107265346A) discloses a maintenance lifting platform for automobile maintenance. By setting a separate floating plate on the traditional support plate, and the floating plate only needs to be supported at one end, the height adjustment of both sides can be achieved, which saves manufacturing cost and use cost, and can achieve the height adjustment of both ends of the vehicle after lifting, which is more convenient for maintenance workers to operate. In the process of implementing this solution, it was found that the following problems exist in the prior art and have not been well solved:
[0004] Existing cars often need door-to-door maintenance when they are being overhauled, but the lifting platform cannot cope with the situation of door-to-door maintenance when in use, which makes its use limited. Secondly, the hydraulic cylinder needs to be overhauled during use, and the hydraulic cylinder needs to be disassembled during the overhaul process, making the disassembly of the hydraulic cylinder more difficult.

[0031] A first rotating rod 9 is connected to the bottom of the floating plate 2, and a movable block 8 is connected to the inner side of the first rotating rod 9. The movable block 8 is used to quickly fix and disassemble the extension rod 11, which is convenient for subsequent maintenance and separation. An extension rod 11 is arranged inside the movable block 8, and a second rotating rod 12 is connected to the inside of the extension rod 11. The second rotating rod 12 is used to connect the support plate 13, which facilitates the support plate 13 to support the car. The inner side of the second rotating rod 12 is connected to the support plate 13, and a fixed block 10 is connected to the bottom of the extension rod 11.

The bottom plates 4 are symmetrically distributed on both sides of the device body 1. Sawtooth blocks 5 are evenly and equidistantly distributed below the bottom plate 4. The sawtooth blocks 5 strengthen the grip of the bottom plate 4 to ensure that the hydraulic cylinder 3 is stable when used alone.
[0033] See the attached drawings in the specification Figure 1-5 The connection between the hydraulic cylinder 3 and the hydraulic rod 6 is a piston connection. The hydraulic cylinder 3 and the base plate 4 are installed in an integrated manner. The hydraulic rod 6 and the fixed block 10 are installed in an integrated manner. The hydraulic cylinder 3 cooperates with the hydraulic rod 6 to drive the fixed block 10 to rise and fall, thereby ensuring the subsequent lifting and lowering of the floating plate 2.
[0034] See the attached drawings in the specification Figure 1-5 The rubber layer 7 fits tightly against the hydraulic rod 6, the center point of the rubber layer 7 coincides with the center point of the hydraulic cylinder 3, the diameter of the rubber layer 7 is larger than the diameter of the bottom plate 4, the number of rubber layers 7 is consistent with the number of hydraulic cylinders 3, and the rubber layer 7 is used to seal the periphery of the hydraulic rod 6 to prevent debris from entering the connection between the hydraulic rod 6 and the device body 1, thereby facilitating the protection of the device body 1.
