AI Technical Summary
The existing level gauge float is prone to hitting the inner wall of the level gauge housing when it is bumpy, and hitting the same position for a long time will cause leakage.
A structure is designed in which the float can rotate around the center of the detection connecting rod, equipped with a guide sleeve and a lubricating bushing to reduce friction, and a limit plate is used to limit the rotation range of the float to avoid long-term collision with the same position.
It effectively avoids long-term collision between the float and the level gauge housing, prevents leakage, and improves the service life and reliability of the level gauge.

Abstract
Description
Technical Field
[0001] The present invention relates to the field of liquid level gauges, and in particular to a liquid level gauge float. Background Art
[0002] At present, the float of the existing liquid level gauge is fixed at the bottom of the detection connecting rod. When the liquid level gauge is bumpy, the float is easy to hit the inner wall of the liquid level gauge shell. If it hits the same position for a long time, leakage is likely to occur. There is a lack of a liquid level gauge float that can avoid hitting the same position. Summary of the Invention
[0003] The purpose of the present invention is to provide a liquid level meter float to address the above-mentioned deficiencies.
[0004] The invention comprises a detection connecting rod and a floating ball. The floating ball is movably installed at the bottom of the detection connecting rod and can rotate around the detection connecting rod as a center.
[0005] A guide sleeve is provided in the middle of the float, and the guide sleeve is sleeved on the bottom of the detection connecting rod.
[0006] A set of lubricating bushings is provided on the outer wall of the detection connecting rod. When the float rotates, the inner wall of the guide sleeve contacts the lubricating bushings.
[0007] A pair of limiting plates are provided at the bottom of the detection connecting rod, and the lubricating bushing is located between the pair of limiting plates.
[0008] The limiting piece is welded to the outer wall of the detection connecting rod.
[0009] The guide sleeve is welded inside the float, and a hollow area is formed between the outer wall of the guide sleeve and the inner wall of the float.
[0010] The lubricated bushing is a polytetrafluoroethylene bushing.
[0011] The number of lubricating bushings in a set is two.
[0012] The limiting piece is an annular limiting piece, and the diameter of the limiting piece is greater than the diameter of the guide sleeve.
[0013] The present invention has the advantages that the float ball can rotate around the detection connecting rod, thereby avoiding long-term collision with the same position and preventing leakage. BRIEF DESCRIPTION OF THE DRAWINGS
