Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit the utility model.
As shown in Figure 1, 2, the utility model is related to a kind of plastic air filter assembly installation nut fixed structure, filtering
Device assembly, which is docked by upper-lower casing end face and installed by nut, to be fixed, wherein setting connection spiral shell in filter assembly upper shell
The lower connecting base 2 of attaching nut is set on female upper connecting base 1 and filter assembly lower house, during installation, by nut from upper company
The aperture of screwed hole 4 in the cell body 3 of the upper surface of joint chair 1 is screwed into, and upper connecting base 1 and lower connecting base 2 are linked into an integrated entity.
As shown in Figure 1, 2, the cell body 3 in the upper surface of upper connecting base 1 in the lateral surface of upper connecting base 1 opens up notch, keeps away
Exempt from limitation of the size of cell body 3 to the nut size of installation nut, when installing nut, nut nut can be spilt outside cell body 3, protected
Card nut nut is installed in place in the cell body 3 for installing fixed structure.
