The invention discloses an oil drain overhauling device which comprises a cover plate for being fixed to an oil drain opening. A through hole penetrating through the cover plate is formed in the cover plate. The cover plate is provided with a first boss, the side wall of the first boss is provided with a groove for embedding sealing rings, and the middle of the first boss protrudes upwards to form a second boss. The through hole is located in the middle of the second boss. The upper portion of the through hole is provided with a blocking ball, wherein the diameter of the blocking ball is larger than that of the through hole and the blocking ball can block the through hole through oil pressure. The edge of the through hole is provided with at least three bolts for preventing the blocking ball from disengaging. According to the oil drain overhauling device, the blocking ball sinks downwards under the action of the oil pressure, a screw hole is blocked, oil liquid is prevented from flowing out, and the temporary sealing function is achieved. When oil drain is needed, the blocking ball is supported up through a tool, and the oil liquid flows out through seams. The oil drain overhauling device is simple in structure and capable of preventing dirt blocking due to the fact that the second boss is arranged at the position of the through hole.
Description
technical field [0001] The invention relates to an oil discharge device for maintenance. Background technique [0002] The current maintenance and oil discharge device generally uses a spring and a screw plug to cooperate with each other, and the screw plug acts as a jacking force under the action of the spring, but the structure is complicated, and the oil flow cannot be controlled during the maintenance and oil discharge, which easily causes oil leakage. Flow out randomly, causing pollution and waste, and the complicated structure is easy to be blocked. Contents of the invention [0003] The purpose of the present invention is to provide an inspection and maintenance oil discharge device which is simple in structure, easy to use and not easy to be blocked. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a maintenance oil discharge device, including a cover plate for fixing on the oil discharge port, the cover pl...
