AI Technical Summary
In existing filter installation structures, the spring plate is prone to friction with the slot when the filter is removed, leading to difficulty in removal or damage to the spring plate, which affects maintainability and reliability.
It adopts a W-shaped spring plate design. The main body of the spring plate is composed of three bends. The two ends are fixed to the filter frame by fasteners. The bottom bend point deforms and sinks into the receiving cavity, which is coordinated with the gap self-adjustment. The middle section has an arc-shaped structure to improve the smoothness of sliding.
This makes filter installation and removal smoother, avoids damage to the spring plates, improves maintainability and reliability, ensures controllable deformation of the spring plates, avoids jamming, and enhances the installation stability of the filter.
