Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to a stainless steel joint for an automobile engine oil level sensor. Background Art

[0002] A joint is a component used to connect pipes and is widely used in oil circuit systems. It has good mechanical properties and sealing properties. The main function of the oil level sensor is to detect the amount of oil in the fuel tank and transmit real-time oil level information to the car's control system. It is generally connected to the fuel tank through a joint or flange, and the float is extended to the inside of the fuel tank. The movement of the float in the fuel tank changes the signal of the resistor, thereby determining the liquid level of the fuel tank. The connection method in the prior art generally uses flanges and joints for connection. However, due to the volatility of gasoline and when there is enough gasoline in the car's fuel tank but encounters a bumpy road section, the gasoline in the tank shakes and splashes. The connection between the flange and the joint is likely to cause gasoline to leak from the connection, resulting in poor sealing effect and a safety hazard. Utility Model Content

[0003] The utility model provides a stainless steel joint for an automobile engine oil level sensor, which solves the problems of poor sealing effect and potential safety hazards in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] Automobile engine oil level sensor stainless steel connector, including

[0006] main body;

[0007] A medium channel, the medium channel runs through the main body;

[0008] The characteristic is that the medium channel includes an installation section, a one-way flow guide is arranged in the installation section, the one-way flow guide includes an outer shell, an elastic member and a one-way flow cover, the one-way flow cover is arranged in the outer shell, the elastic member is arranged in the one-way flow cover and connected to the outer shell, and the one-way flow guide is used to realize one-way flow of the medium in the medium channel, so that gasoline can only flow from one direction and cannot pass through the oil level sensor connection, thereby preventing gasoline from flowing back or leaking.

[0009] Furthermore, a limiting surface is formed between the installation section and the medium channel, and the limiting surface is used to limit the one-way flow guide component and determine the installation position of the one-way flow guide component to facilitate installation.

[0010] Furthermore, a sliding groove is provided in the outer shell, and the single-flow cover cooperates with the sliding groove. The single-flow cover moves along the sliding groove, which plays a guiding and limiting effect. When the elastic part is compressed, it drives the single-flow cover to move along the sliding groove. When the elastic part is reset to no pressure or the pressure is less than the elastic force, the elastic part drives the single-flow cover to move in the opposite direction or stop.

[0011] Furthermore, a guide hole is penetrated through the single-flow cover, and a flow groove connected to the sliding groove is provided in the outer shell. The guide hole and the flow groove are in communication. When the single-flow cover allows the medium to flow, the medium enters the flow hole from the flow groove and enters the medium channel. When the single-flow cover is in the opposite direction and cannot allow the medium to pass through, the medium cannot pass through the flow groove.

[0012] Furthermore, a limiting groove communicating with the flow groove is provided in the shell, and a sealing ring is provided in the limiting groove. The sealing ring will fit tightly on the surface of the single-flow cover to form a sealing interface to prevent the medium from leaking from the gap, effectively improve the sealing of the connection, and prevent gasoline leakage.

[0013] Furthermore, a sealing groove is provided in the shell, and a sealing member is provided in the sealing groove. The sealing member has good elasticity and corrosion resistance and can maintain stable sealing performance under various working conditions. Its function is to fill the tiny gap between the sealing groove and the surface to be sealed through its elastic deformation, thereby preventing medium leakage.

[0014] Furthermore, the medium channel also includes a connecting section connected to the installation section, the connecting section is provided with an internal thread, and the main body is threadedly connected to the oil level sensor. The threaded connection makes the installation and disassembly process simple and quick, improves the efficiency of maintenance and replacement, and at the same time, a tight sealing surface is formed at the connection between the two to effectively prevent medium leakage.

[0015] Furthermore, a positioning portion is provided on the installation section and a positioning groove is provided on the outer shell. The positioning portion and the positioning groove cooperate to ensure that the joint can be quickly and accurately aligned with the outer shell during installation, thereby speeding up the installation speed. Accurate alignment and firm connection can improve the reliability and service life of the joint and reduce failures and maintenance costs caused by loose connections or leakage.

[0016] Furthermore, a base is detachably connected to the shell, and the elastic member is connected to the base. The detachable connection mode of the base and the shell makes the installation and maintenance of the joint simple and convenient, thereby improving the work efficiency.

[0017] Furthermore, a snap-in groove is provided on the shell, and the base is snap-into the snap-in groove, which has a positioning effect and is convenient for disassembly and assembly.

[0018] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0019] The utility model discloses a stainless steel joint for an automobile engine oil level sensor, wherein a medium channel comprises a mounting section, a one-way flow guide is arranged in the mounting section, the one-way flow guide comprises a shell, an elastic member and a one-way flow cover, the one-way flow cover is arranged in the shell, the elastic member is arranged in the one-way flow cover and is connected to the shell, and one-way flow of the medium in the medium channel is achieved through the one-way flow guide, so that gasoline can only flow through from one direction and cannot pass through the oil level sensor connection, thereby preventing gasoline from flowing back or leaking and improving the sealing effect.
