Description
Technical field
The utility model is related to liquid sensor technical fields, and in particular to a kind of fuel level sensor.
Background technology
Fuel level sensor is to enter after container the variation for causing capacitance between sensor housing and induction electrode using oil,
And this change transitions is detected to the part of oil position in container for curent change, existing fuel level sensor is usually by electric appliance
Box, mounting flange, straight-bar and the fuel feed hole being set on straight-bar and gas vent form, and electrical appliance kit is fixed on by mounting flange
The top of fuel tank.Its shortcoming is：Only upper end is fixed, when straight-bar is long or vehicle on uneven road when driving, with
The shaking of fuel tank intermediate fuel oil, the rotator inertia that oil float generates can be such that straight-bar shakes, easily cause the deformation of fuel level sensor straight-bar,
Root run cracks, oil float clamping stagnation, and fuel level sensor service life is short.
Utility model content
The technical problem to be solved by the utility model is in view of the above shortcomings of the prior art, provide one kind preventing vehicle
The fuel level sensor that fuel level sensor shakes in driving process.
To achieve the above object, the utility model provides following technical solution：A kind of fuel level sensor, including fuel oil
Case, electrical appliance kit, signal wire, mounting flange, the straight-bar being connect with mounting flange and the fuel feed hole being set on straight-bar and exhaust
Hole, it is characterized in that：The mounting flange radial edges are equipped with auxiliary fixing device, and the auxiliary fixing device is equipped with for installing
In the installation component on fuel tank, the straight-bar is equipped with flexible pre-tightening mechanism.
Further setting is the utility model：The auxiliary fixing device includes for detaining mounting flange edge
" 7 " font fastener, the fastener are equipped with the bed course for preventing scratching mounting flange with mounting flange junction.
Further setting is the utility model：The installation component includes that fuel tank end face outside corresponds to fastener position and sets
There is an installation part, the fastener and installation part corresponding position are equipped with the identical threaded hole of coaxial and diameter, are equipped in the threaded hole
Threaded post.
Further setting is the utility model：The flexible pre-tightening mechanism includes straight-bar axially away from mounting flange one end
End is equipped with extension, and the extension is fixed with connector, and the connector is axially arranged with spring, the spring outwards packet
It is wrapped with shell, the shell is equipped with vessel, and the spring is fixedly connected with vessel axial end face, and the vessel diameter is not less than
Connector diameter, outer side contact inner wall of oil tank end face are equipped with non-slip mat.
Further setting is the utility model：End face outside is equipped with strainer at the straight-bar fuel feed hole.
The utility model as characterized above：Auxiliary fixing device reinforces the connection of mounting flange and fuel tank, increases
Bonding strength, flexible pre-tightening mechanism are fixed on the bottom of fuel tank, and the spring of flexible pre-tightening mechanism can buffer the shaking of straight-bar, also
It is absorbable make, the accumulated error that installation process is brought, effectively avoid the shaking of fuel tank inner fluid and caused by straight-bar shake
It is dynamic, the problems such as oil float clamping stagnation, measurement error, the service life of fuel level sensor is extended, measuring accuracy, strainer mistake are improved
Impurity in fuel is filtered, prevents impurity effect fuel level sensor from working.
The utility model is described in further detail with reference to the accompanying drawings and examples.
