Description

Technical Field

[0001] This utility model relates to the technical field of ventilation duct devices, specifically a composite air duct with a perlite graphite silicon fireproof board. Background Technology

[0002] Air ducts are a common indoor and outdoor air circulation system. Their structure generally includes a main air duct, a secondary air duct, and a fan.

[0003] For example, a composite air duct with a floating fireproof board disclosed in the authorized announcement number includes an air duct body, on which fireproof boards are provided on all four side walls. A first angle steel is installed on two adjacent fireproof boards. The first angle steel and the fireproof board are fixed to each other by nails. A docking component for connecting the air duct body is provided on the air duct body.

[0004] When installing this composite duct with beaded fireproof panels, workers need to connect the side walls of the insulated composite duct to each other and press the four fireproof panels firmly against the four side walls of the insulated panel to initially stabilize the fireproof panels. Then, workers need to connect the four first angle steels to the fireproof panels and secure them with nails.

[0005] As can be seen from the solutions disclosed in the existing patent documents, the structural design of using multiple nails to fix the fireproof board will damage the installation integrity of the fireproof board and make it inconvenient to install the fireproof board quickly. In addition, the connection parts of the air duct body are fixed and connected by multiple screws, which is inconvenient for the quick connection and installation of the air duct body. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0008] The ventilation duct is provided with a connecting mechanism at its end for quick connection and installation of the duct. The end of the ventilation duct is connected to a connecting frame, and a snap-fit ​​frame is provided on the outside of the connecting frame. A sealing ring is glued to one side of the connecting frame, and one side of the sealing ring is in close contact with the connecting duct. A screw is threaded to the lower end of the connecting frame, and a positioning pin is connected to the lower end of the screw. A pin cap is connected to the lower end of the positioning pin, and a limit block is slidably sleeved on the outside of the positioning pin.

[0009] Preferably, one side of the left support block is in close contact with the right support block, and the ventilation duct and the connecting duct are internally connected.

[0010] Preferably, the end of the fireproof board is tightly attached to the connecting frame, and the other end of the mounting frame is connected to a right support block.

[0011] Preferably, a sealing ring is fitted inside the snap-fit ​​frame, and the snap-fit ​​frame is connected to the air duct.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This composite air duct with a beaded graphite silicon fireproof board uses a mounting frame to secure the fireproof board to the outer surface of the ventilation duct. The fireproof board is tightly attached to the outer surface of the ventilation duct, and the left and right support blocks are connected by rotating and tightening screws. This facilitates the installation of the fireproof board.
