AI Technical Summary

Technical Problem

Existing fresh air system mounting brackets suffer from insufficient adjustability, poor vibration resistance, weak installation adaptability, and complex structure that makes maintenance inconvenient, making it difficult to meet the needs of diverse installation scenarios.

Method used

The system adopts a combined design of a support frame, adjustment components, damping modules, and auxiliary positioning units. The support frame includes a main load-bearing beam and a crossbeam. The adjustment components consist of horizontal and vertical adjustment rods. The damping modules consist of spring plates and damping pads. The auxiliary positioning units consist of positioning blocks and positioning pins. Multi-directional adjustment and damping are achieved through threaded pairs, snap-fit ​​connections, and nested connections.

Benefits of technology

It achieves precise positioning of the fresh air system in multiple directions, effectively absorbs vibration, simplifies the installation process, improves connection stability and construction efficiency, and adapts to the needs of different wall conditions and equipment weight.
