Description

Technical Field

[0001] The utility model relates to the technical field of lifts, in particular to an outer guardrail of a lift. Background Art

[0002] A lawn mower is also called a lawn mower, a lawn mower, a lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns and vegetation. It is composed of a cutter, an engine, a running wheel, a frame, an armrest, and a control part. After the lawn mower is used, a lift is required to place it and perform subsequent maintenance.

[0003] Among them, the existing patent CN202320392091.2 is a double-column lift hydraulic cylinder. The double-column lift hydraulic cylinder obtained by the above design can be used. When the hydraulic cylinder body needs to be repaired, the piston rod of the hydraulic cylinder body is controlled to retract, so that the lifting arm is against the bottom plate, the threaded sleeve and the threaded cap are rotated to make the threaded sleeve and the threaded cap separate from the semi-threaded column, and then the locking piece is rotated to unscrew the locking piece, open the second shell, and the hydraulic cylinder body can be taken out from the first shell. After the repair of the hydraulic cylinder body is completed, the activity of the hydraulic cylinder body is controlled. The plug rod retracts to the initial position, and then the hydraulic cylinder body is clamped into the clamping groove, the second shell is closed, and the locking piece is threaded through the connecting plate. When the hydraulic cylinder body is fixed in the first shell, the semi-threaded column is also fitted with the piston rod of the hydraulic cylinder body, and then the threaded sleeve and the threaded cap are threaded on the semi-threaded column and the piston rod of the hydraulic cylinder body, and the lift can be used. The hydraulic cylinder of the double-column lift only needs to remove one locking piece, and unscrew the threaded sleeve and the threaded cap to realize the disassembly of the hydraulic cylinder body, which saves time and effort and improves the maintenance efficiency of the hydraulic cylinder body.

[0004] However, the contact area between the bottom support of the existing lift and the ground is relatively fixed. As the lifting height increases, when the contact area with the ground is smaller, it will cause its operation to be unstable. At the same time, when the contact point between the lift and the vehicle deviates from the center of gravity of the vehicle, it will inevitably cause uneven force on the contact point between the hydraulic rod of the lift or its base and the ground, thereby causing the lawn mower to slip. Therefore, it does not meet the existing needs. We have proposed an outer guardrail for the lift. Utility Model Content
