AI Technical Summary

Technical Problem

The existing curtain wall ventilator's damper opening and closing mechanism lacks a stop position in both the open and closed states, which makes the damper easy to fall off or be blown open, and generates noise when closing.

Method used

The spring hinge flip-top mechanism includes a hinge bracket, hinge shaft, spring, connecting rod, hinge slide shaft and slide plate. Through the elastic action of the spring and the limiting structure, the damper is stopped and buffered, preventing the damper from falling off the bottom frame and reducing closing noise.

Benefits of technology

It effectively prevents the damper from detaching from the bottom frame when opening, reduces closing noise, and ensures the stability and quietness of the damper in all states.
