AI Technical Summary

Technical Problem

Aluminum alloy doors and windows cannot effectively reduce external noise in a noisy environment, and when trying to increase sound insulation, ventilation performance will be greatly reduced.

Method used

A sound-proof and noise-reducing aluminum alloy doors and windows are designed, and an adjustable window cover mechanism is used to cooperate with the sliding window body by covering the outside of the door and window openings. The gear shaft, gear, and rack structure are used to realize the movement of the frame cover frame, and the indoor and outdoor air flow exchange is achieved through the angle adjustment of the air guide plate.

Benefits of technology

The window cover mechanism is adjusted according to the noise size, which can not only effectively reduce noise, but also increase ventilation effect when the noise is small, and improve the practicality of the form.

Abstract

The invention discloses a sound insulation and noise reduction aluminum alloy door and window which comprises a sliding window body installed on a door and window hole. The door and window further comprises a window cover mechanism covering the outer side of the door and window hole. The window cover mechanism comprises a frame cover frame and sound insulation glass installed in the frame cover frame. A translation structure for moving the frame cover frame is mounted at the top of the window cover mechanism and comprises a plurality of racks fixedly mounted at the top of the frame cover frame and gears meshed with the racks, and the gears are fixedly connected through gear shafts; the gear shaft is fixed on a wall body through a wheel shaft frame; the gear shaft is driven through a chain wheel transmission structure; the window cover mechanism further comprises a supporting pulley structure. The door and window further comprises an air guide mechanism, and airflow is guided through the air guide mechanism to enter a room through the ventilation gap. The invention further discloses an adjusting method for adjusting the door and window between noise and ventilation. According to the technical scheme, noise reduction and ventilation are both considered, and the technical defect that a traditional window body sacrifices ventilation through sound insulation is perfectly overcome.
