As optimization, described elastic buffering pad is sheathed on the outer side position of the whole external peripheral surface of cartridge filter and radial two end surfaces to form cover shape structure.Like this, elastic buffering pad is sheathed fixing more reliable and stable.
As optimization, the fixing part of described mounting bracket be U-shaped like structure and spiro keyhole position in the neutral position of U-shaped structural base, the flap that the both sides of described fixing part U-shaped structure extend formation two transverse section curved to outer camber line obtains described assembly department, the inner chamber that two flaps surround and elastic buffering pad outer peripheral surface coupling are configured for the installation cavity installing cushion pad and inner filtration cylinder thereof, form the card interface entering installation cavity for elastic buffering pad and inner filtration wound packages thereof between the seamed edge of described two flaps away from fixing part.
Like this, mounting support structure is simple, takes up room little, and makes to install the fast easier for installation of cushion pad and inner filtration cylinder thereof.
Further, described elastic buffering pad has one section of reducer vertically to form step vertically at its outer surface, and the surface of internal cavity that described flap surrounds is disposed radially the ledge structure of coupling.
Like this, laminating between elastic buffering pad and its installation cavity better can be allowed tight, prevent from moving axially, improve and install reliably.
Further, described flap two ends along its length have the catch edge that inwardly protruding is formed, and catch edge is used for the edges at two ends position that elastic buffering pad and inner filtration cylinder thereof are lived in clamping.
Like this, can prevent from further moving axially equally, improve installation reliability.
Further, described flap forms flange away from the seamed edge neck-out of fixing part.Like this, more can be beneficial to the installation of installing cushion pad and inner filtration cylinder thereof to snap in.
Further, the bottom integrated of described fixing part U-shaped structure is planar, and described spiro keyhole position is in intermediate position, and bolt hole two edge is upwards heaved perpendicular to the direction of U-shaped structure both sides and is formed with twice stiffening rib.
Like this, adopt minimum consumptive material at utmost to improve structural strength around bolt hole, improve and connection reliability is installed.
Further, the bottom of described fixing part U-shaped structure is also provided with along an end margin of cartridge filter axis the positioning block being bent downwardly and extending to form.When can make like this to install, conveniently first position by positioning block.
In sum, it is simple that the utility model has structure, installs good stability, and assemble the very convenient advantage such as fast.
