Automatic filter screen locking device

Abstract

The invention discloses an automatic filter screen locking device. The automatic filter screen locking device comprises a fixed housing, a filter screen and a locking device, wherein the filter screenis fixedly mounted inside the fixed housing; the locking device is movably connected to the inner part of the fixed housing and is positioned on the side surface of the filter screen; the top surfaceof the fixed housing is fixedly connected with a limiting plate; a slide slot is formed in the inner side surface of the limiting plate; a pulling rod is fixedly mounted inside the locking device; the two ends of the pulling rod are fixedly connected with first springs; limiting slots are formed in positions, on the edges of the first springs, of the two ends of the pulling rod; blocking blocks are movably blocked inside the limiting slots; fixed columns are arranged inside the first springs in a sleeved mode; upper and lower ends of each first spring are fixedly blocked with connecting slots; and the first springs sleeve the outer surfaces of grooves. The automatic filter screen locking device can avoid affecting use effect of a fan as loosening and sliding are caused by vibration of thefilter screen, and the like, so that use stability is improved.

Description

technical field [0001] The invention relates to the technical field of filter screen automatic locking equipment, in particular to a filter screen automatic lock device. Background technique [0002] The fan is a machine that converts the mechanical energy of rotation into gas pressure energy and kinetic energy, and transports the gas out. The filter screen is an important part of the fan. The air sent in from the outside can be filtered through the filter screen. Fan products are transported all over the world, but in the existing technology, the filter screen cannot be well fixed in the fan. During the transportation process, the filter screen is easy to loosen and slide due to vibration and other reasons, which affects the use effect of the fan. , In the working process of the fan, the filter screen is also prone to loosening and sliding, so an automatic locking device for the filter screen is needed to solve the above-mentioned problems.
