Description

Technical Field

[0001] The utility model relates to the technical field of air duct connection, in particular to a connecting suspension for a metal composite fire-resistant air duct. Background Technique

[0002] A metal composite fire-resistant air duct is a new type of air duct integrating a metal layer, a heat insulation layer, and a fire-resistant layer. While meeting the fire resistance limit requirements of the technical standards for building smoke prevention and exhaust systems, it also has advantages such as beauty, light weight, and convenient installation. The core material of this air duct is the metal composite fire-resistant air duct board, which integrates the traditional fire-resistant layer, heat insulation layer, and metal layer into one board, reducing the thickness of the air duct board, improving the heat resistance performance and service life. Connecting suspensions usually refer to metal components used to connect each section of the air duct, ensuring the integrity and tightness of the air duct system.

[0003] After retrieval, the document with the publication number "CN215909352U" mentions that "the utility model provides a connecting member for a metal composite fire-resistant air duct, belonging to the technical field of air duct connection, including an air duct; the air duct is a rectangular hollow structure; there are two first connecting frames in total, and both of the two first connecting frames are clamped on the outer side of the air duct; the connecting member is jointly composed of a second connecting frame and a sealing gasket, and the connecting member is installed between two groups of first connecting frames; the silica gel cloth is arranged between two second connecting frames." It fixes the air duct by clamping buckles, but the air duct itself will generate certain vibrations during operation, so that during long-term use, the fasteners on the air duct are likely to become loose, resulting in the air duct shaking and the connection between the air ducts becoming loose, affecting the use effect of the air duct.

[0004] Therefore, we provide a connecting suspension for a metal composite fire-resistant air duct to solve the above problems. Content of the Utility Model

The front and rear ends of the inner side of the connecting frame 1 are pin-connected with the movable clamping plate 213. The inner side of the movable clamping plate 213 is provided with the clamping spring 214. Place the connecting air duct 211 on both sides of the connecting frame 1, and then push the connecting air duct 211 inward to contract the clamping spring 214. After pushing the connecting air duct 211 to the designated position, the clamping spring 214 loses pressure, pushes up the movable clamping plate 213, and snaps into the connecting card slot 212 to fix the connecting air duct 211 and prevent it from falling off during use.

[0028] Further, movable slots 215 are arranged on the upper and lower sides of the movable clamping plate 213. The inner side of the movable slot 215 is slidably connected with the release push plate 216. Push the release push plate 216 inward to push the movable clamping plate 213 to contract the clamping spring 214, so that the movable clamping plate 213 disengages from the connecting card slot 212, and the connecting air duct 211 can be quickly removed from the connecting frame 1, improving the convenience of installation and disassembly of the connecting air duct 211.

[0029] Further, the fixing component 22 includes a movable fixing plate 221, a fixing bolt 222, a compression spring 223, a compression top plate 224, a supporting spring plate 225 and a spring telescopic rod 226.

After pushing the connecting air duct 211 to the designated position, the clamping spring 214 loses pressure and pushes up the movable clamping plate 213, which is clamped into the connecting clamping groove 212 to fix the connecting air duct 211 and prevent it from falling off during use. In the second step, push the release push plate 216 inward to push the movable clamping plate 213 and make the clamping spring 214 contract, so that the movable clamping plate 213 disengages from the connecting clamping groove 212, and the connecting air duct 211 can be quickly removed from the connecting frame 1, improving the convenience of installation and disassembly of the connecting air duct 211. In the third step, turn the fixing bolt 222 to fix the connecting air duct 211 from above through the movable fixing plate 221, ensuring the stability of the installation of the connecting air duct 211. At the same time, through the compression energy storage of the compression spring 223, ensure that the compression top plate 224 can be better fixed above the connecting air duct 211, exerting a mutual force on the fixing bolt 222 and the connecting air duct 211, ensuring the firmness of the installation of the connecting air duct 211 and avoiding the loosening of the fixing bolt 222.
