Abstract

The invention relates to a self-expansion oil pipe connector and a using method of the self-expansion oil pipe connector. The self-expansion oil pipe connector mainly comprises an oil pipe connector body and a driving block arranged in the oil pipe connector body. The driving block is provided with multiple pushing keys protruding out of the wall of the oil pipe connector body, and the surfaces of the pushing keys are oblique planes. A spring used for pushing the driving block is arranged in the oil pipe connector body. A limiting screw for mounting is arranged on the wall of the oil pipe connector body. After the oil pipe connector is mounted, the limiting screw can be directly screwed out, self-moving of the driving block can be achieved, the pushing keys will drive a rubber ring wrapping the outer wall of the oil pipe connector body to expand while moving, and therefore the binding force between the oil pipe connector and the wall of an oil pipe can be increased.

Description

technical field [0001] The invention relates to a self-expanding oil pipe connector and a method for using the same, belonging to the field of oil supply pipe connectors for hydraulic equipment. Background technique [0002] With the rapid development of industry and more and more large-scale equipment, hydraulic pressure is widely used in many driving or load-bearing fields; [0003] First of all, in the field of construction, in order to reduce the impact of the construction site on the local environment (such as the dust brought by cement powder), it is generally used to make prefabricated parts outside the construction site, and then move them to the construction site for assembly by large machinery. ; [0004] Furthermore, in the mining industry, the demand for coal mines and stone materials is also increasing. Traditional small-scale excavation machinery can no longer meet the current demand. If the local production and construction of related equipment can save costs...
