Problems solved by technology

[0002] At present, the general hydraulic jack is composed of oil suction oil passage, oil pressure oil passage, oil discharge oil passage, base, piston cylinder, and manual plunger pump. It is widely used, but in some other occasions, it is necessary to use the jack upside down or lay it flat. At this time, due to the structural reasons of the existing jack, the existing jack cannot be used upside down or laid flat, which not only causes some work. Trouble, and also limits the range of jacks that can be used

Abstract

The utility model relates to a novel jack structure, a main oil suction pipe, a high-pressure channel and an oil drainage channel are pre-arranged on a base; a one-way valve is arranged at the outlet end of the high-pressure channel; a piston cylinder is installed and fixed on the upper surface of the base; a three-way valve is arranged at the middle part of an oil tank, and a conversion handle of the three-way valve is positioned outside the oil tank; an oil suction pipe A and an oil suction pipe B are respectively connected with the three-way valve; the two ends of the main oil suction pipe are respectively communicated with a manual hydraulic pump and one of channels of the three-way valve; a piston is installed in the piston cylinder; an adjusting screw rod is installed on the piston; and an oil discharge valve is installed at the position in the middle of the oil drainage channel on the base.

Description

technical field [0001] The invention relates to a jack structure, in particular to a novel jack structure, and belongs to the technical field of hydraulic jacks. Background technique [0002] At present, the general hydraulic jack is composed of oil suction oil passage, oil pressure oil passage, oil discharge oil passage, base, piston cylinder, and manual plunger pump. It is widely used. However, in some other occasions, it is necessary to use the jack upside down or lay it flat. At this time, due to the structural reasons of the existing jack, the existing jack cannot be used upside down or laid flat. This not only causes some work. The hassle, at the same time, also limits the jack's range of use. Contents of the invention [0003] The object of the present invention is to provide a new type of jack structure, which has strong adaptability and effectively expands the application range of the jack. [0004] The technical scheme adopted by the present invention to achiev...
