Description

Diesel-oil filter

Technical field

The utility model relates to a kind of automobile-used filtration system, particularly a kind of diesel-oil filter.

Background technique

The filter cleaner that is used for diesel oil filtering in the automobile is of a great variety; It mainly is made up of housing, the element kit be located in the housing; The filter paper that its filter core is generally center tube and is provided with around center tube; The axial two ends of center tube are respectively equipped with upper end cap and lower end cap, and upper end cap is provided with filtering outlet, seal through Sealing between upper end cap and lower end cap and the filter paper.Usually, filter cleaner need be connected with the ponding cup in the car, and its joint is the plastic socket that the lower end of housing is provided with, and an end of this plastic socket is connected with housing, and the other end then is used for and the socket connection of ponding cup.Yet because the Placement between plastic socket and the housing is a brushing glue between housing and plastic socket, such Placement is not only operated inconvenience, and has influence on the sealing of inner member easily.

Summary of the invention

To the deficiency that existing technology exists, the utility model provides a kind of assembling and diesel-oil filter simple in structure, compact structure.

For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of diesel-oil filter; Include housing and be located at the element kit in the housing, the filter paper that element kit includes center tube and is provided with around center tube, the axial two ends of center tube are respectively equipped with upper end cap and lower end cap; Upper end cap is provided with filtering outlet; Through the Sealing sealing, housing is positioned at the lower end cap place and is provided with the plastic socket that is connected with housing, it is characterized in that: described housing is provided with some hooks towards the end face of plastic socket between upper end cap and lower end cap and the filter paper; Be provided with locating groove between hook and the housing, the side that said plastic socket and housing are fitted is arranged in the locating groove.

Wherein, Housing is provided with four hooks towards the end face of plastic socket; Four hooks are in twos and are symmetrical set, and plastic socket includes ponding cup attachment portion and standing part, and its ponding cup attachment portion is a strip shape body; The horizontal strip shape body of standing part for being vertical setting with strip shape body and fitting with housing, the standing part of plastic socket extends in the locating groove at housing hook place.

Adopt technique scheme; Through at the locating groove that is provided with on the housing between hook and hook and the housing, make to be connected more compactly between plastic socket and the housing, need not gluing; Plastic socket just can keep positioning relation with housing; And such set-up mode is simple in structure, the device convenient, can shorten installation time, enhances productivity.

The utility model further is set to: Sealing includes the sealing block of being located between filter paper and upper end cap and the lower end cap.

Adopt technique scheme, the setting of sealing block makes and keeps sealing between filter paper and upper end cap and the lower end cap.

Below in conjunction with accompanying drawing the utility model is further described.
