Description

Technical Field

[0001] This utility model belongs to the field of fireproof air vent technology, and in particular relates to an openable and closable fireproof air vent. Background Technology

[0002] Fireproof air vents are safety devices installed at the end of ventilation and air conditioning systems. They are mainly used to prevent the spread of fire and smoke through the ventilation system in the event of a fire. Fireproof air vents are usually made of non-combustible materials, while rotating parts are made of corrosion-resistant metal materials to ensure their stability and durability in a fire. Fireproof air vents will automatically close when the temperature reaches 70°C to isolate the fire source. Fireproof air vents play an important role in building fire protection systems, effectively controlling the spread of fire and smoke, and protecting the lives and property of people.

[0003] However, the existing openable and closable fireproof air vents adopt an integral structure, which requires disassembly before operation during maintenance and replacement, resulting in reduced maintenance efficiency and making it impossible to achieve rapid maintenance and replacement of openable and closable fireproof air vents. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an openable and closable fireproof air vent.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An openable and closable fireproof air vent includes a first fireproof air vent housing and a second fireproof air vent housing. Both the first and second fireproof air vent housings are provided with connecting teeth. A connecting plate is fixedly connected to the connection between the first and second fireproof air vent housings. A plurality of through connecting screw holes are correspondingly opened on the connecting plate, and connecting bolts are threaded into the connecting screw holes.

[0007] Preferably, a locking nut corresponding to the connecting bolt is fixedly connected to the second fireproof air vent housing.

[0008] Preferably, multiple buffer rubber pads are fixed at the outer edge where the first fireproof air vent housing and the second fireproof air vent housing connect.

[0009] Preferably, both the first fireproof air vent housing and the second fireproof air vent housing are provided with grooves corresponding to the positions of the connecting teeth.

[0010] Preferably, a ventilation channel is connected between the first fireproof air vent housing and the second fireproof air vent housing.

[0011] Preferably, the first fireproof air vent housing and the second fireproof air vent housing are connected by a connecting tooth engagement on their respective meshing surfaces.

[0012] Beneficial effects: In this utility model, the fireproof air vent can be fixed by installing two connecting plates and connecting bolts on opposite sides of the first and second fireproof air vent shells, thus achieving a rapid assembly effect and improving the practicality of the fireproof air vent. At the same time, the connecting bolts can tightly fix and splice the connecting plates, thereby improving the firmness of the fireproof air vent installation. Furthermore, the interlocking action between the first and second fireproof air vent shells can prevent displacement during use, increasing the stability of the fireproof air vent.
