Description

Technical Field

[0001] This utility model relates to the technical field of oil level floats, and in particular to an oil tank oil level float. Background Technology

[0002] Oil level floats are a common liquid level measuring component used in automobiles, motorcycles, and storage tanks. They primarily function by moving a variable resistor or switch up and down, thus displaying the oil level on the dashboard. Oil level floats include metal and plastic floats. While they are inexpensive and easy to manufacture, they also have some inherent drawbacks. Traditional metal floats are characterized by high cost, heavy weight, slow response, corrosion resistance, chemical stability, and high temperature resistance. Traditional plastic floats are characterized by low cost, light weight, fast response, but are not corrosion-resistant, not heat-resistant, and have low strength. Neither type of float can simultaneously possess all the advantages of the other, failing to meet the needs of users and the market. Utility Model Content

[0003] The purpose of this invention is to provide an oil tank level float that is high in strength, lightweight, fast in response, and resistant to high temperatures.

[0004] The purpose of this utility model is achieved as follows:

[0005] An oil tank level float includes a cover and a cylinder. The top and bottom of the cylinder are open, and the cover is placed on top of the cylinder. The cover has a through hole in its center. Both the cover and the cylinder are made of rigid foam. The bottom edge of the cover is embedded in the cylinder and connected to the inner wall of the cylinder. The cover and the cylinder have a honeycomb structure. The density of the cover and the cylinder is 50 to 100 kg / m³, and the pore size of the honeycomb structure is 0.05 mm to 0.1 mm. The elastic modulus of the rigid foam is 350 MPa to 500 MPa. Compared with metal floats and ordinary plastic floats, the honeycomb structure of this invention results in a fuel tank level float with high hardness, low density, light weight, fast response speed, and high temperature resistance.

[0006] The present invention can be further improved in the following ways.

[0007] The bottom edge of the cover is bonded to the inner wall of the cylinder, making the structure of this utility model more robust.

[0008] The inner wall of the cylinder is provided with a reinforcing protrusion ring, which makes the strength of this utility model higher.

[0009] The inner wall of the cylinder is provided with a support boss on the upper part, and the bottom edge of the cover sits on the support boss and is connected to the support boss.

[0010] The bottom edge of the cover is bonded to the supporting boss, which makes the structure of this utility model more robust.

[0011] The top of the cover has a groove with an annular step inside, and the through hole is located in the center of the groove.

[0012] The lid is shaped like a frustum.

[0013] Rigid foam is a closed-cell foam plastic, which makes it difficult for fuel to penetrate and corrode the float of this invention.

[0014] The beneficial effects of this utility model are as follows:

[0015] Compared to metal floats and ordinary plastic floats, the honeycomb structure of this invention makes the oil level float of this invention have high hardness, low density, light weight, fast response speed, and high temperature resistance. Attached Figure Description
