Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
Referring to Fig.1-3, a kind of outer guard of air filter of gasoline engine, including mounting base 1, the upper surface of mounting base 1 offer fixation
Slot 12 symmetrically opens up on the side wall of fixing groove 12 there are two card slot 13, is placed with sealing shroud 7 in fixing groove 12, sealing shroud 7 it is upper
End face is fixedly installed with containment envelope 2, and the upper surface of containment envelope 2 is fixedly installed with upper cover plate 3, is provided in containment envelope 2
Filter body 4 symmetrically opens up on the side wall of sealing shroud 7 there are two spring groove 14, slidably connects in each spring groove 14
Slide plate 9 is fixedly connected with spring 8 on the side wall of slide plate 9, and the other end of spring 8 is fixedly connected on the side wall of spring groove 14,
Slide plate 9 is fixedly connected with fixture block 10 away from one end of spring 8, and the other end of fixture block 10 runs through the side wall of sealing shroud 7 and is against card
In slot 13, each fixture block 10 is slidably connected in the side wall of sealing shroud 7, and fixture block 10 is trapezoidal away from one end of slide plate 9, card slot
