Embodiment Construction

[0019] The application will be described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific embodiments are only used to further illustrate the application, and cannot be interpreted as limiting the protection scope of the application. The above application content makes some non-essential improvements and adjustments to this application.

[0020] combine figure 1 and figure 2 As shown, a liquid level sensor pipeline connection and positioning structure, the liquid level sensor includes an information tube 1 and a fixing frame 2, and of course other existing structures, such as oil pipes, wire harness pipes, floats, top seats, etc., all pipes The tops of the pipelines are all connected to the top base, and can be sealed and fixed with epoxy resin, while the bottoms of other pipelines except the information tube 1 are directly connected with the fixing frame 2 through rivets. The improvement of the p...

Abstract

The invention discloses a pipeline connection and positioning structure of a liquid level sensor. The liquid level sensor includes an information tube and a fixing frame. The connection and positioning structure includes: a plug connected to the bottom end of the information tube; A first plug-in part is formed; a second plug-in part is set on the fixing frame; the first plug-in part is plugged into the second plug-in part from the non-information tube length direction to realize the connection and positioning of the information tube. This structure inserts and fits the bottom of the information tube and the fixing frame, replacing the traditional rivet connection, so that the information tube cannot be rotated or shaken, effectively avoiding the phenomenon that the information tube falls off and the float touches other pipelines The phenomenon of not being able to slide up and down guarantees the service life and the detection accuracy of the sensor; more importantly, this structure helps to determine the positioning reference point of the entire sensor, and install the sensor based on this reference point.

Description

technical field [0001] The invention relates to the technical field of liquid level sensors, in particular to a pipeline connection and positioning structure of a liquid level sensor. Background technique [0002] The vehicle fuel level sensor is generally composed of a top seat, an information tube, a float, an oil suction pipe, a wire harness tube, a fixing frame and other components. The bottom end of the filter is positioned by the fixing frame, and the fixing frame can also be used to install the filter screen assembly of the oil suction pipe. Through the cooperation of the top seat and the fixing frame, there is a certain gap between the pipelines and they are kept parallel to each other. [0003] Among them, for the installation of the information tube and the fixing frame, the specific connection method currently used is to open a hole in the fixing frame, directly connect the information tube to the opening position of the fixing frame, and then use rivets to fix t...
