Problems solved by technology

[0002] At present, in the installation process of the oil level sensor, the oil level sensor is directly installed on the fuel tank through the flange. The fuel tank contains a lot of fuel, and the fuel has a certain fluidity. When the road conditions are poor, the fuel will have more impact on the fuel level sensor, which will cause damage to the rod or floating body of the fuel level sensor, reducing the service life of the fuel level sensor and increasing the cost of use.

Embodiment Construction

[0014] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0015] Such as figure 1 As shown, the present invention is an oil level sensor for a fuel tank. The oil level sensor device installed on the fuel tank 1 includes a circuit box 2, a signal line 3, a flange 4, and a rod body 5. A floating body is provided on the side of the rod body. The floating body includes a football-like float 6 arranged vertically, the axis position of the float is pierced with a floating column 7, and the float is rotatably connected with the floating column, and the floating column slides through the swing arm 8 and the rod body. The contact piece 9 is connected.

[0016] A buffer sleeve 10 is sheathed on the outside of the rod body...

Abstract

The invention discloses a fuel tank oil level sensor. An oil level sensor device installed on a fuel tank includes a circuit box, a signal line, a flange plate, and a rod body. A rod body side is provided with a floating body. The floating body includes a vertically-arranged rugby-body-shaped floater. A floating column passes through an axis position of the floater. The floater is rotatably connected to the floating column. The floating column is connected to a slide contact sheet in the rod body through a swing arm. The floater of the oil level sensor is in a vertically-arranged smooth rugbyshape, and the floater is rotatably connected to the floating column. When a vehicle is running or a road condition is poor and the vehicle is shaking, an impact force of fuel oil in the fuel tank tothe oil level sensor is generally the impact force in a front-rear direction, and then when the floater is impacted, a smooth surface and a rotatable characteristic of the floater can buffer or discharge a lot of the impact force so as to prolong a service life of the floater.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a fuel tank oil level sensor. Background technique [0002] At present, in the installation process of the oil level sensor, the oil level sensor is directly installed on the fuel tank through the flange. The fuel tank contains a lot of fuel, and the fuel has a certain fluidity. When the road conditions are poor, the fuel will have more impact on the fuel level sensor, which will cause damage to the rod or floating body of the fuel level sensor, reducing the service life of the fuel level sensor and increasing the cost of use. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and provide a fuel tank oil level sensor with simple structure, impact resistance, non-damage and prolonged service life. [0004] In order to achieve the above object, the technical solution of the present invention is to design an oil leve...
