Abstract
The utility model discloses an oil leakage prevention structure of an automobile engine oil filling machine, which comprises an oil inlet pipeline and an oil filling nozzle, wherein the oil filling nozzle is connected with the oil inlet pipeline through an oil filling nozzle fixing seat; the oil inlet pipeline is provided with a one-way valve and an air blowing joint; the blowing joint is arranged at the lower end of the one-way valve, an oil leakage prevention baffle plate is arranged at the position of a connecting port of the oil filling nozzle fixing seat and the oil inlet pipeline, and the blowing joint is arranged at the tail end of the one-way valve, so that residual oil can be blown along the flow direction of a pipeline to blow out the residual oil; the oil leakage prevention baffle can prevent engine oil which flows down due to poor sealing, and the engine oil can not leak from the outlet of the oil filling nozzle, so that the purpose of preventing leakage is achieved.
Description
Technical Field
The utility model relates to an automobile engine machine oil filling machine technical field specifically is an automobile engine machine oil filling machine's leak protection oil structure.
Background
After the automobile engine is assembled and tested on a production line, quantitative engine oil needs to be filled into the engine; current tanker aircraft nozzle structure still has the residual oil to leak out from the oil filler hole after refueling, drips on the engine, causes the quality bad, and its reason includes: (1) a certain distance is reserved between the outlet of the oil filling nozzle and the one-way valve, and after the oil filling valve is closed, a certain amount of engine oil remains in a pipeline between the one-way valve and the outlet of the oil filling nozzle; (2) in the prior art, residual oil in a pipeline is blown out by blowing, but the oil product has viscosity and is attached to the inner wall of the pipeline, so that the residual oil cannot be blown out completely; (3) the air blowing port is opposite to the oil inlet, residual oil can flow reversely when air is blown, and the residual oil flows back and leaks after air blowing is stopped; (3) fittings in the pipeline, such as one-way valves, pipe fittings and the like, have limited sealing performance and still have oil leakage.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an automobile engine machine oil filling machine's leak protection oil structure for solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
an oil leakage prevention structure of an automobile engine oil filling machine comprises an oil inlet pipeline and an oil filling nozzle, wherein the oil filling nozzle is connected with the oil inlet pipeline through an oil filling nozzle fixing seat; the oil inlet pipeline is provided with a one-way valve and an air blowing joint; the method is characterized in that: the air blowing joint is arranged at the lower end of the one-way valve, and an oil leakage prevention baffle plate is arranged at a connecting port of the oil filling nozzle fixing seat and the oil inlet pipeline.
Preferably, the oil inlet pipeline is connected with the oil filling nozzle through an elbow pipe fitting.
Preferably, an upward extending plate is arranged on the oil filling nozzle fixing seat and on the inner side of the oil inlet pipeline connecting port to form the oil leakage preventing baffle.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides an oil leakage prevention structure of an automobile engine oil filling machine, wherein a blowing joint is arranged at the tail end of a one-way valve, so that residual oil can be blown along the flow direction of a pipeline to blow out the residual oil; the oil leakage prevention baffle can prevent engine oil which flows down due to poor sealing, and the engine oil can not leak from the outlet of the oil filling nozzle, so that the purpose of preventing leakage is achieved.
