Description

Automobile pipeline plastic quick connector with secondary locking mechanism

Technical Field

The utility model relates to the technical field of quick connectors for automobile pipelines, in particular to a plastic quick connector for an automobile pipeline with a secondary locking mechanism.

Background

The automobile pipeline system comprises an oil pipe (such as an oil inlet pipeline, an oil return pipeline and the like), a water pipe (such as a cooling water circulation pipeline, an antifreezing solution pipeline and the like) and an air pipe (such as a crankcase ventilation pipeline, a ventilation pipeline and the like). The pipelines can be quickly connected according to the requirements of installation, maintenance, modularized arrangement, space and the like in the whole vehicle arrangement. The quick connector is the most common connection mode because of the characteristics of convenient connection, no need of tools, simple operation and the like. The quick connector generally comprises a female connector and a male connector, wherein the female connector and the male connector are connected to form a passage. However, the conventional quick connector generally uses an elastic structure, and is assembled with the male connector by means of the bolt deformation opening to be enlarged and inserted, and the buckling locking is buckled with the flange table of the male connector by means of the rebound of the bolt. Through the use of market research and automobile factories, the connection mode is found to have the problem that male and female connectors cannot be confirmed in use, so that the connectors fall off in use, or the elastic lock spring loses elasticity due to long-term heating or external force, so that the connectors fall off. This uncontrollable and not accurately identifiable connection is a long-felt problem for automotive factories.

The principle of the automobile pipeline plastic quick connector adopting the secondary locking mechanism is that the flange table of the male connector is blocked by the fifth limiting boss of the lock catch, the locking is realized by not relying on the elastic deformation principle of a conventional lock spring, the connector is not separated due to the fact that the lock catch is invalid due to long-term heating or stress, whether the male connector is assembled in place or not can be confirmed according to whether the tail end of the lock catch protrudes out of the guide groove of the locking arm after secondary locking, and the phenomenon that the male connector falls off due to the fact that the connection condition of the male connector cannot be confirmed is avoided.

However, after the locking, the secondary locking is needed to be performed again by an operator, the operation is troublesome, and the oil pipe is generally arranged in the automobile pipeline, so that the installation is more inconvenient due to the fact that the oil leakage exists during the installation.
