This utility model discloses a terminal air vent connection assembly suitable for small-sized suspended ceilings, including a square base box, a flexible compressible hose, a terminal air vent connector, a terminal air vent base, a round-to-square fitting, a circular flexible bendable pipe, and a fresh air branch pipe connector. The square base box is fixed to the bottom of the floor slab. The flexible compressible hose is connected to the bottom of the square base box and is connected to the terminal air vent connector. The terminal air vent connector is fixedly connected to the terminal air vent base, and the terminal air vent base is fixed to the suspended ceiling plasterboard. The side of the square base box is connected to the circular flexible bendable pipe via the round-to-square fitting, and a fresh air branch pipe connector is provided at the end of the circular flexible bendable pipe. This utility model reduces the ceiling height required for air vent installation and allows for the selection of square or circular air vents. By optimizing the structural design of the terminal air vent connection assembly, it saves ceiling space and improves indoor space comfort.

This utility model discloses a pressure-resistant gift box, comprising an outer box and an inner box. A support frame is provided around the inner box and between it and the outer box. Several partitions are provided inside the inner box. A lid is connected to one side of the outer box, and a protrusion is provided on the inner side of the lid. Several support plates are connected to the protrusion. The outer box, inner box, lid, support plates, and partitions are all made of corrugated cardboard, while the support frame is made of plastic. This pressure-resistant gift box, through the combination of the inner and outer boxes and the support frame, forms a multi-layered pressure-resistant structure, effectively buffering external impacts and preventing damage to gifts due to squeezing and collision. The precise alignment of the support plates and partitions enhances overall stability and prevents gifts from shifting or moving. The use of corrugated cardboard as the main material reduces costs and is environmentally friendly, while the plastic support frame ensures the strength of key components; the material combination is reasonable.
