Description

Technical Field

[0001] This utility model relates to the field of household fresh air system technology, and in particular to a terminal air outlet connection component that can be used in small-sized ceiling heights. Background Technology

[0002] Currently, most branch pipes for fresh air systems have an outer diameter of 75mm. The minimum ceiling clearance required for installing standard terminal connectors and vents is approximately 200mm. For smaller ceiling heights, vent placement and design are significantly limited. Furthermore, when using square vents, additional round-top-square-bottom fittings are needed, further increasing the ceiling height requirement. Utility Model Content

[0003] To address the aforementioned issues, this utility model aims to provide a terminal air vent connection component that can be used in small-sized ceiling heights, thereby solving the problem of insufficient overall installation height after combining the "height required for duct bends + height of air vent base + height of air vent edge" when the ceiling height is small.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A terminal air vent connection assembly that can be used in small-sized suspended ceilings includes 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 surface of the floor slab. The bottom of the square base box is connected to the flexible compressible hose, the lower end of which 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 square end of the round-to-square fitting, the circular end of which is connected to the circular flexible bendable pipe, and a fresh air branch pipe connector is provided at the end of the circular flexible bendable pipe.

[0005] The square base box is provided with lifting lugs at its four corners. The lifting lugs are connected to the lifting rods, and the upper end of the lifting rods is fixed to the bottom surface of the floor slab.

[0006] The upper end of the flexible compressible hose passes through the hole in the bottom plate of the pull-out box and is fixedly connected to the flange and the bottom plate of the pull-out box by rivets. The flange is located above the bottom plate of the pull-out box, and the lower end of the flexible compressible hose is connected to the end air outlet connector by socket.

[0007] The square base box includes a square base box body, a bottom groove, and a pull-out base plate. The bottom of the square base box body is provided with a square opening and a bottom groove. The bottom groove is located on the outside of the square opening. The pull-out base plate has a folded edge on one side. The pull-out base plate is inserted into the bottom groove to connect with the square base box body.

[0008] The terminal air outlet connector is provided with a sealing ring groove, and a sealing ring is provided in the sealing ring groove.

[0009] The terminal air vent base is fixed to the ceiling plasterboard with screws.

[0010] The lower part of the terminal air outlet base is provided with a terminal air outlet decorative panel, which is fixedly connected to the terminal air outlet base through a rotating or sliding connecting slot.

[0011] The flange ring is square or round, the holes on the pull-out base plate are square or round, and the flexible compressible hose, the end air outlet connector, and the end air outlet base are square or round.

[0012] Compared with the prior art, the present invention has the following advantages: 1. This utility model can reduce the ceiling height required for air vent installation, solving the problem of insufficient overall installation height after combining the "height required for duct bends + height of air vent base + height of air vent edge" when the ceiling height is small. This product can also be used for air vent installation in ordinary ceiling heights. By optimizing the structural design of the terminal air vent connection components and making reasonable combinations, ceiling space is saved, and indoor space comfort is improved.

[0013] 2. This utility model can be configured with either a square or round air outlet, solving the problem that when a non-circular air outlet is used in interior decoration, a transition connector is needed, which increases the required installation height, but the ceiling height cannot be increased.

[0014] 3. The components of this utility model fit together tightly without air leakage; the air outlet connector and the air outlet base are transitioned by a groove and a sealing ring, resulting in good airtightness. Attached Figure Description

The circular end of the round-to-square fitting 3 is connected to the circular flexible bendable pipe 2. The end of the circular flexible bendable pipe 2 is provided with a fresh air branch pipe connector 1. Fresh air branch pipe connector 1 is used to connect the pipe to the branch pipe of the fresh air system; round flexible bendable pipe 2 is used to connect the fresh air branch pipe connector 1 and the round-to-square fitting 3 on site; round-to-square fitting 3 is used to convert the round fresh air pipe into a square interface to connect to the square base box body 4.

[0019] The square base box has lifting lugs 5 at its four corners, which are connected to a suspension rod 19. The upper end of the suspension rod 19 is fixed to the bottom surface of the floor slab 18. The square base box is fixed to the bottom surface of the floor slab 18 by the suspension rod 19 and the lifting lugs 5.

[0020] The upper end of the flexible compressible hose 10 passes through a hole in the pull-out base plate 9 and is fixedly connected to the flange ring 8 and the pull-out base plate 9 by rivets. The flange ring 8 is located above the pull-out base plate 9. The lower end of the flexible compressible hose 10 is socketed to the end air vent connector 11. As shown in the figure, the length of the flexible compressible hose 10 can be compressed and extended according to the ceiling height.

[0021] The square base box includes a square base box body 4, a bottom groove 6, and a pull-out base box plate 9. The bottom of the square base box body 4 is provided with a square opening and the bottom groove 6. The bottom groove 6 is located on the outside of the square opening. The pull-out base box plate 9 has a downward-curved edge on one side. The pull-out base box plate 9 is inserted into the bottom groove 6 to connect with the square base box body 4.

[0022] The terminal air outlet connector 11 is provided with a sealing ring groove 12, and a sealing ring 13 is provided in the sealing ring groove 12 for sealing between the terminal air outlet connector 11 and the terminal air outlet base 15.

[0025] First, fix the square base box to the bottom surface of the floor slab, and then connect the round-to-square fitting 3, the round flexible bendable pipe 2, and the fresh air branch pipe connector 1 in sequence. Next, pass one end of the flexible compressible hose 10 through the hole on the pull-out base box base plate 9, and secure it with the flange ring 8. Then, use rivets 7 to fix the upper end of the flexible compressible hose 10 to the flange ring 8 and the pull-out base box base plate 9. Then, connect the other end of the flexible compressible hose 10 to the terminal air outlet connector 11 via a socket joint. After completing the above connections, use the lower edge of the pull-out base box base plate 9 as a handle to push the pull-out base box base plate 9 into the bottom sliding groove 6 of the base box body 4, achieving a fixed connection with the base box body 4. The flange ring 8 is pressed between the base box body 4 and the base box body 4. After the terminal air outlet connector 11 is fixedly connected to the terminal air outlet base 15, the terminal air outlet base 15 is fixed to the ceiling plasterboard 14 with screws 17.
