Description

Technical Field

[0001] This utility model relates to the technical field of fireproof air vent equipment, and in particular to a fireproof air vent with a variable isolation chamber. 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, existing fireproof air vents often adopt a fixed isolation chamber design, which can meet basic fire protection requirements, but suffers from delayed sealing response and insufficient high-temperature resistance in complex fire scenarios. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing fireproof air vents often use a fixed isolation chamber design, which can meet basic fire protection requirements but suffers from delayed sealing response and insufficient high-temperature resistance in complex fire scenarios. Therefore, this invention proposes a fireproof air vent with a variable isolation chamber.

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

[0006] A fireproof air vent with a variable isolation chamber includes an air vent shell, an isolation chamber inside the air vent shell, an air vent body inside the isolation chamber, a servo motor fixedly connected to the bottom end of the isolation chamber, a drive wheel fixedly connected to the end of the output shaft of the servo motor, a driven wheel meshing with a driven wheel, a protrusion fixedly connected to the driven wheel, an adjustment mechanism between the protrusion and the air vent body, and limiting mechanisms on both sides of the air vent body.

[0007] As a further improvement of this utility model, the adjustment mechanism includes a drive arm rotatably connected to the protrusion, a fixed shaft is fixedly connected to the side wall of the air outlet body, an adjustment arm is rotatably connected to the fixed shaft, and a connecting shaft is rotatably connected between the adjustment arm and the drive arm.

[0008] As a further improvement of this utility model, the limiting mechanism includes a limiting groove provided on the inner side wall of the air vent housing, a sliding rod fixed in the limiting groove, a sliding block slidably connected to the sliding rod, and the sliding block being fixedly connected to the air vent body.

[0009] As a further improvement of this utility model, a plurality of evenly distributed fixing plates are provided on the outer side wall of the air vent housing, and the fixing plates are provided with locking screws for fixing them to the air vent housing.

[0010] As a further improvement of this utility model, a support shaft is fixedly connected to the bottom end inside the air vent housing, and the support shaft is rotatably connected to the driven wheel.

[0011] As a further improvement of this utility model, the protrusion is disposed at the edge of the driven wheel surface.

[0012] The beneficial effects of this utility model are:

[0013] 1. In this utility model, a servo motor drives the active wheel to rotate. The meshing action between the active wheel and the driven wheel drives the driven wheel to rotate on the support shaft. The protrusion on the driven wheel follows the rotation of the driven wheel, driving the drive arm to rotate. The drive arm is connected by a connecting shaft, driving the adjusting arm to rotate around a fixed shaft, thus pushing the air outlet body to move. During the movement of the air outlet body, the sliding block connected to it slides on the sliding rod, achieving stability during the movement of the air outlet body and realizing variable adjustment of the isolation chamber.

[0014] 2. The fireproof air vent with a variable isolation chamber solves the problem of delayed response of traditional fireproof devices in high-temperature environments by setting up the variable isolation chamber, thus improving the safety of use. Attached Figure Description
