Description

Technical Field

[0001] The utility model relates to the technical field of multi-section separable hydraulic jacks, and particularly relates to a multi-section separable hydraulic jack. Background Technique

[0002] A hydraulic jack is driven by human or electric power to a hydraulic pump, transmitted through a hydraulic system, and uses a cylinder body or a piston as a lifting member. The separable hydraulic jack is separated from the hydraulic pump and connected by a high-pressure hose in the middle. It consists of a cylinder body and a piston rod. An oil hole is provided on the cylinder body. The bottom end of the cylinder body is supported on the ground. A piston head is installed at the upper end of the piston rod. When the hydraulic pump supplies oil to the cylinder body, the piston rod moves out along the direction of the cylinder body. After the piston head jacks up the equipment to be lifted to a predetermined height, it is locked by a hydraulic lock in the oil circuit to ensure the lifting height of the equipment. The hydraulic jack has a compact structure, can smoothly jack up heavy objects, works stably, has a self-locking function, and has a relatively high transmission efficiency.

[0003] The contact area between the upper end of the existing multi-section separable hydraulic jack and an object is small, so it cannot be jacked up well during use.

[0004] Therefore, a multi-section separable hydraulic jack is needed to improve the above problems. Content of the Utility Model
