The specific embodiment
Below in conjunction with the drawings and specific embodiments present technique is described in further detail.
Embodiment 1:
Referring to dustproof accessory skeleton interface shown in Fig. 1-3, comprise for the supporter 1 that supports filter bag, be used for being installed in installation sleeve 2 on the dust collector box body, be fixed on the Venturi tube 3 in the installation sleeve.Supporter comprises ring set 11 and the keel shoe 12 that links to each other up and down; 4 bails 6 are arranged on the ring set.Be provided with sealing ring 4 between ring set top and the installation sleeve.
The flanging 21 of the upper end of installation sleeve is fixed on the dust cleaning case housing 5, has 4 draw-in grooves 22 at ring set.The opening 23 of draw-in groove is in the bottom of ring set.Draw-in groove comprises vertically 221, two sections tilting sections 222 of section, 223 of an end.The axis of tilting section and ring set is in an acute angle, and vertically section parallels with the axis of ring set.Vertically section 221 is extended from the draw-in groove lower ending opening along the ring set axis direction and is linked to each other with the tilting section 222 that is tilted to, the other end of tilting section 222 and be tilted under tilting section 223 join.Be connected with the bail 6 that radially extends along ring set on the top of supporter; Bail is identical with draw-in groove quantity, all is distributed on the week of line centered by the ring set axis upwards.Bail is successively through vertically section 221, tilting section 222 arrive tilting section 223.Because tilting section 223 is tilted to down, can prevent that bail 6 is from wherein slippage.
