The inner end of the positioning rod groove is connected with a fixing sleeve, the inner part of the fixing sleeve is connected with a sliding block, the sliding block slides in the fixing sleeve, the middle part of the sliding block is propped against the positioning rod, the sliding block is connected with one end of a supporting spring, the other end of the supporting spring is connected with a first fixing plate, and the first fixing plate is clamped in the fixing sleeve.
Has the advantages that:
the installation convex rod is clamped on the air filter screen, so that the air filter screen and the air channel are accurately positioned in the installation process, and convenience is brought to the installation of the air filter screen. The installation cover is fixed in the mounting groove, and installation cover and wind channel connection structure are stable. Spacing protruding card makes airstrainer can fix in the mounting groove on airstrainer for airstrainer is accurate with the connection location in wind channel, and facilitates for the fixed of second fixed plate, makes airstrainer can not drop at the fixed in-process of second fixed plate, reduces the possibility that takes place the skew in the second fixed plate installation, and then has improved the stability of relative structure between second fixed plate and wind channel. The fixture block card is in the locating lever outer end, makes the locating lever can promote the stopper, makes spacing arch card on air cleaner. When the fixture block retracts into the mounting sleeve, the sliding block pushes the positioning rod outwards to enable the positioning rod to be taken out, the limiting block slides towards the outer side of the positioning rod groove under the support of the reset spring, the limiting protrusion is separated from the air filter screen, so that the air filter screen can be taken out from the mounting groove, and the air filter screen is convenient to replace.
