[0002] The existing fire prevention smoke exhaust ventilation pipeline is mostly integrated forming mechanism, and punch forming is relatively convenient, but it still has certain defects in use: because it is an integrated forming structure, the volume of the pipeline is large, so the land occupation area is large, and then it is inconvenient to carry, transfer and transport, the transportation cost is increased, and the pipelines are mostly connected and fixed by bolts, so the installation and disassembly are relatively inconvenient, so it is necessary to design a combination formula fire prevention smoke exhaust ventilation which can be quickly assembled and disassembled to facilitate transportation. CONTENT OF THE UTILITY MODEL

[0003] In order to overcome the defect that the ventilation pipeline is mostly integrated forming structure in the prior art, which is inconvenient for transportation and leads to high transportation cost, one of the purposes of the utility model is to provide a combination formula fire prevention smoke exhaust ventilation.

[0004] One of the objectives of this utility model is achieved through the following technical solution: Based on a combined fireproof smoke exhaust ventilation system, it includes a first ventilation duct mechanism: the first ventilation duct mechanism includes a first side plate, a second side plate is provided on one side of the first side plate, a first groove and a second groove are symmetrically provided on one side of both the first side plate and the second side plate, a first plate overlaps the inner wall of the first groove, an upper top plate is fixedly connected to the upper surface of the first plate, a second plate overlaps the inner wall of the second groove, a lower bottom plate is fixedly connected to one side of the second plate, inserts are symmetrically fixedly connected to one side wall of both the upper top plate and the lower bottom plate, a first magnetic block is fixedly connected to one side of each insert, slots are symmetrically provided on the other side wall of both the upper top plate and the lower bottom plate, a second magnetic block is fixedly connected to the inner wall of each slot, and one side of the first ventilation duct mechanism...

It facilitates the assembly of the first ventilation duct mechanism, making it more convenient to carry and transport compared to a one-piece molded ventilation duct. It also occupies less space. Furthermore, the magnetic assembly method makes installation and disassembly easier than the traditional threaded assembly, thus effectively improving assembly efficiency.

[0005] According to the combined fireproof and smoke-exhausting ventilation system, a first sealing gasket is fixedly connected to one side of both the upper top plate and the lower bottom plate. This facilitates improved sealing performance of the assembled connection.

[0006] According to the combined fireproof and smoke-exhausting ventilation system, the working principle and structure of the second ventilation duct mechanism are consistent with those of the first ventilation duct mechanism. This facilitates the combination and connection of multiple ventilation ducts.

[0007] According to the combined fireproof and smoke-exhausting ventilation system, the second ventilation duct mechanism has symmetrically arranged slots on one side near the insert block.

[0011] According to the combined fireproof and smoke-exhausting ventilation system, the outer surfaces of the upper top plate, the lower bottom plate, the first side plate, and the second side plate are all coated with fire-retardant paint. This effectively improves the overall fire-resistant and flame-retardant performance of the first and second ventilation duct systems.

The rotating fixed rod drives the pull rod to rotate on the inner wall of the through hole and the insertion hole, so that the third magnetic block and the fourth magnetic block are magnetically attracted to each other, thereby assembling the first ventilation duct mechanism stably. At the same time, the magnetic assembly method is more convenient for installation and disassembly, and the small footprint makes it easy to transport and carry, effectively improving assembly efficiency and reducing transportation costs.

[0014] 2. By setting up the first reinforcing frame, the second reinforcing frame, the threaded hole, the second sealing gasket, and the screws, the first reinforcing frame and the second reinforcing frame are installed and fixed at the connection between the first ventilation duct mechanism and the second ventilation duct mechanism through the screws and the threaded hole, and the gap at the connection is sealed by the second sealing gasket, thereby effectively improving the connection stability and sealing between the first ventilation duct mechanism and the second ventilation duct mechanism.
