Abstract

The invention discloses a portable jack, which comprises: a disc, a suspension pan, a connecting shaft, and three tripods, wherein the surface of the connecting shaft has threads, and the middle part of the disc is connected to the A screw hole is provided in the middle of the suspension plate, and the connecting shaft passes through the screw hole to fix the suspension plate below the disc, and the two ends of the connecting shaft are fastened with nuts; wherein, the 3 One end of each tripod is connected to the disc through a bolt, and the other end is connected to a base, wherein the tripod is composed of a first main body frame and a second main body frame, and the first main body frame is connected to the second main body frame. N positioning holes are provided on the surface of the second main body frame, and bolts are used to pass through the positioning holes and cooperate with nuts to fix between the first main body frame and the second main body, realizing the structural design of the lifting device Reasonable, high-efficiency, low-cost, convenient and fast, and no material waste.

Description

technical field [0001] The invention relates to the field of electric equipment research, in particular to a portable jack. Background technique [0002] With the advancement and development of science and technology, the demand for electricity in people's life and production is increasing, and the equipment, construction, and maintenance of the corresponding power sector are also increasing year by year. Heavy equipment for auxiliary work. [0003] In the prior art, wooden squares and iron wires were often used to lap the lifting frame on site in the past temporary lifting operations. Such an operation method is time-consuming and laborious, and after the operation is completed, the lifting frame needs to be disassembled in time to exit the operation site , resulting in a waste of material. Or utilize large-scale hoisting equipment, and large-scale equipment cannot utilize in mountainous area, and cost is higher. [0004] To sum up, in the process of realizing the techni...
