Oil atomizer base with reverse locking function

Abstract

The invention relates to the technical field of oil supply systems of oil engines, and particularly relates to an oil atomizer base with a reverse locking function. The oil atomizer base with the reverse locking function is composed of an operation rod, a cup body, a combination barrel, a protruding edge, a slice groove, a leaf spring, a bolt, a spring, a spring groove, a rotating disc, a bolt groove, an anchoring seat, an operation hole, a positioning groove and a positioning block. The barrel-shaped cup body is integrated with the combination barrel. The cup body is placed below the combination barrel, and the outer diameter of the cup body is smaller than that of the combination barrel. The circular protruding edge is placed on the connection position of the cup body and the combination barrel. A through hole is formed on an oil pipe. The protruding edge is inserted in the through hole. The anchoring seat is Elliptic cylindrical, and the operation hole is placed in the middle of the anchoring seat. The oil atomizer base with the reverse locking function can not loose under long-term high-frequency vibration, and compared with the prior art, the oil atomizer base with the reverse locking function has better durability and stability.

Description

technical field [0001] The invention relates to the technical field of a fuel engine fuel supply system, in particular to a fuel injector base with a reverse locking function. Background technique [0002] The connection process between the fuel injector base and the fuel pipe is usually processed by resistance welding. Because the resistance welding process is quite complicated and there are many uncontrollable factors, the welding quality is not stable. At the same time, there is damage to the material itself during welding. Destruction, so it is not the optimal connection scheme. [0003] In the prior art, there is also a technical solution to directly fix the fuel injector base to the oil pipe by riveting and expanding the core pulling die, but this connection only relies on the expanded side wall of the base and the wall of the through hole of the oil pipe. The friction force between them realizes a fixed connection. Although this connection method is easy to operate, ...

[0003] In the prior art, there is also a technical solution to directly connect the fuel injector base to the fuel pipe by riveting and expanding the core pulling die, but this connection method only relies on the expanded side wall of the base and the through hole wall of the fuel pipe. The friction force between them realizes a fixed connection. Although this connection method is easy to operate, it has poor stability and durability, and it will loosen under the long-term high-frequency vibration of the engine.
