The hose connected with the oil inlet pipe is also provided with annular flanges which are arranged in sequence, and positioning grooves are formed at intervals among the annular flanges.

And a metal ring is arranged in the pipe joint, a through hole matched with the window is arranged on the metal ring, and the through hole is communicated with an inner hole of the metal ring.

And a dust cover is also arranged on the pipe joint.

The utility model discloses a structure, can make the filter body pass through the fixed plate and make location and fixed, the reliability and the stability of this body coupling of filter have been guaranteed, the coupling of hose end makes its location through the location picture peg rather than the buckle grafting simultaneously, the location picture peg make the installation more convenient and reliable owing to adopt the buckle connection, guarantee the stability of the connection of its junction, just so can prevent that the connection position of filter body and hose from appearing becoming flexible, avoid leading to leaking the fuel risk because of not hard up gap appearing, reach and connect the reliable technological effect of installation.

The invention is further described with reference to the accompanying drawings and the detailed description.
