Pressure testing device for cabin opening oil cylinder

The utility model discloses a pressure testing device for a cabin opening oil cylinder. The cabin opening oil cylinder is provided with a first oil chamber and a second oil cavity. The pressure testing device comprises a low-pressure oil tank unit, a low-pressure oil pump unit, a control valve unit, an oil pipe connector unit and a high-pressure oil pump unit. The low-pressure oil pump unit is used for conveying hydraulic oil in the low-pressure oil tank unit to the cabin opening oil cylinder. The control valve unit is used for controlling the flow direction of gas, the hydraulic oil or high-pressure oil in the cabin opening oil cylinder. The oil pipe connector unit is used for enabling the high-pressure oil pump unit to be connected with the cabin opening oil cylinder rapidly and displaying testing pressure. The high-pressure oil pump unit is used for improving the testing pressure needed by the cabin opening oil cylinder. The pressure testing device for the cabin opening oil cylinder is simple and reliable in structure and convenient to operate, labor intensity is relieved, the oil loss and pollution are reduced, working efficiency is improved, production cost is reduced, and frequent refueling is avoided.
