Problems solved by technology
[0002] At present, although hydraulic pressure regulating devices are not the same in terms of structural principles and specifications, they generally have the defects of complex structure, high cost, and inconvenient pressure adjustment. For example: Chinese patent number is: 94241769.0, and the patent name is "mechanic "Pressure regulating device", although this technology has certain advantages of convenient pressure regulation, but because the cam mechanism is used as the pressure regulating mechanism, not only the whole mechanism is complicated, the cost is high, but there is also the defect of inconvenient pressure regulation

The invention relates to a pressure regulating device which has a structure that a tubular throttling hood is fixedly arranged in the middle of a base, open slots are symmetrically formed in the right end wall of the throttling hood, and a fixed oil inlet nozzle is installed at the opening of the bottom of the throttling hood. A housing is fixedly installed on the base, a lead screw is fixedly arranged in the middle of the housing by a pressure cover, and a pressure regulating nut is arranged on the lead screw inside an outer cover. The pressure regulating nut is located in an inner hole of the throttling hood, a rolling stopper pin is fixed with the pressure regulating nut through the open slots in both sides of the throttling hood, a valve core is arranged in the throttling hood between the oil inlet nozzle and the pressure regulating nut, and the valve core is connected with the pressure regulating nut through a spring. The pressure regulating device provided by the invention has the advantage of simple structure, and also has the advantage of convenience in pressure regulation.
Description
technical field [0001] The invention relates to a hydraulic control device, in particular to a hydraulic pressure regulating device, which belongs to the technical field of hydraulic control components. Background technique [0002] At present, although hydraulic pressure regulating devices are not the same in terms of structural principles and specifications, they generally have the defects of complex structure, high cost, and inconvenient pressure adjustment. For example: Chinese patent number is: 94241769.0, and the patent name is "mechanic Although this technology has the advantages of convenient pressure regulation, the use of a cam mechanism as a pressure regulation mechanism not only makes the whole mechanism complicated and costly, but also has the disadvantage of inconvenient pressure regulation. Contents of the invention [0003] The purpose of the present invention is to provide a new type of pressure regulating device to overcome the above defects in the exist...
