The utility model has the advantages that: the utility model provides a take liquid level warning plastic power steering oil tank, liquid level warning device is kept apart with the oil tank body, avoids falling the risk that fluid leaked from the liquid level warning device position.
Drawings
Fig. 1 is a cross-sectional view of an embodiment of the present invention.
Detailed Description
For a better understanding of the present invention, the present invention will be further described with reference to the accompanying drawings and examples.
As shown in figure 1, the plastic power steering oil tank with the liquid level alarm comprises an oil tank assembly 1, a liquid level alarm device and a wiring harness 2, wherein the liquid level alarm device comprises an electric protection tube 3, a circuit board 4, a reed pipe 5, a magnetic buoy 6 and a protective sleeve 7, the electric protection tube is arranged in an inner cavity at the bottom of the oil tank assembly and is integrally formed with the oil tank assembly, the circuit board is connected with the reed pipe and is arranged inside the electric protection tube, the magnetic buoy is sleeved outside the electric protection tube, a limit baffle plate 8 is arranged at the top of the electric protection tube, a bottom opening is sealed through the protective sleeve, and one end of the wiring harness penetrates through the protective sleeve and is connected with the connected circuit board.
The electric protection tube is a diameter-variable cylindrical tube with thick bottom and thin top, the inner diameter of the magnetic buoy is larger than the outer diameter of the top of the electric protection tube and smaller than the outer diameter of the bottom, and the magnetic buoy is sleeved on the top of the electric protection tube and has a certain gap with the electric protection tube, wherein the certain gap is 0.8-1.2 mm. The magnetic buoy is a plastic piece and is internally provided with a magnetic ring. The magnetic buoy can not be blocked when moving up and down along the electric protection tube, and the problem of blocked material magnetization can not be caused.
