A cover clip is arranged on the front end of the upper joint surface of the air filter upper cover, and an upper cover elastic clipping hook is arranged on the back end. A clipping groove is arranged on the lower joint surface of the air filter base in corresponding to the upper cover clip, and a clipping hook groove is arranged in corresponding to the upper cover elastic clipping hook. When the upper and the lower joint surfaces are combined, the upper cover clip is completely inserted into the clipping groove, and the upper cover elastic clipping hook is pressed into the clipping hook groove. The utility model has the advantages of avoiding the trouble of screw fixing, convenient assembly and disassembly operation, simple structure, and low cost, etc.

Description

The empty filter housing of general gasoline engines

Technical field

The utility model relates to the housing of general gasoline engines air-strainer, especially the housing made from plastics.

Background technique

Air-strainer mainly is made of housing and filter core, the air-strainer of general gasoline engines is owing to will adapt to the compact design of universal machine, generally smaller, wherein, the housing plastics are made, housing is a thin-shell construction, housing is divided on the sky filter cover and two parts of empty filter base are made respectively, after installing filter core, connect into as a whole mutually with screw, because the air-strainer volume is little, the frequent degree of changing or clearing up filter core is bigger than general bulky air-strainer, and the mode of prior art dismounting screw is made troubles to changing or clear up filter core.

The model utility content

The purpose of this utility model is: provide a kind of general gasoline engines empty filter housing, mounting or dismounting are convenient when replacing or cleaning filter core.

The empty filter housing of general gasoline engines of the present utility model comprises cover and empty filter base on the sky filter, and the front end of the last junction plane that covers on its sky filter is provided with the cover card, and the rear end is provided with the cover elastic fastening hook; On the following junction plane of described empty filter base, the cover card is provided with draw-in groove on the correspondence, and the cover elastic fastening hook is provided with the grab groove on the correspondence; Upper and lower junction plane in conjunction with the time, after last cover card inserts draw-in groove fully, on cover elastic fastening hook and push and snap in the grab groove.Last cover elastic fastening hook free state can not snap in the grab groove, just can snap in the grab groove after must pushing certain elastic deformation, push and unclamp the back elastic return and make and cover elastic fastening hook and can not from the grab groove, deviate from freely, automatically guarantee that the empty filter housing of petrol engine becomes an integral body, reaches the identical effect that screw connects.During installation, after last cover card inserts draw-in groove fully, with hand last cover elastic fastening hook is pushed and to be snapped in the grab groove and get final product; During dismounting, by pressing cover elastic fastening hook card, certain distortion back just can be pulled out, and has removed making the trouble that is screwed from hand, in use, as need renew cartridge more, just can finish whole operations with hand, need not other instruments, extremely convenient, also reduced cost simultaneously.

The described cover card of going up can be arranged two in parallel, on cover elastic fastening hook and be provided with one, on the following junction plane of described empty filter base locating flange can also be set, this locating flange is less than the inside casing that covers on the empty filter.Two upward cover card and upward 3 installations of cover elastic fastening hook formation, reliable and stable, the effect of locating flange has been that leading role is installed, and makes mounting or dismounting convenient.

The advantage of the empty filter housing of general gasoline engines of the present utility model is, removed making the trouble that is screwed from, and the mounting or dismounting operation is extremely convenient, simple in structure, and cost is low.
