Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a fireproof rolling shutter door with a flame retardant function. Background Art

[0002] Rolling shutters are a type of sealing and protective facility suitable for larger portals in buildings. Rolling shutters are generally used in factories, warehouses, shopping malls, etc. Such places are prone to fires, and there are other buildings nearby. If a fire occurs indoors and cannot be effectively controlled, the fire will spread to nearby buildings, causing greater losses and posing a great safety hazard to people. Therefore, rolling shutters are now required to not only have a sealing and protective function but also to be able to protect on-site personnel to a certain extent. That is, when a fire occurs, rolling shutters can play a role in fire prevention and heat insulation, preventing the high temperature in the house from spreading to the outside and preventing the spread of the fire. Most of the existing rolling shutters are made of metal materials, which are not only heavy overall and inconvenient to open and close, but also have poor thermal conductivity. In the event of a fire, it is easy to cause the rolling shutter to be hotter overall and have poor flame retardant function.

[0003] To this end, the utility model provides a fireproof rolling shutter door with flame retardant function. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a fireproof rolling shutter door with flame retardant function to solve the problems raised in the above-mentioned background technology. The utility model can reduce the overall weight of the rolling shutter door body, thereby facilitating the rewinding; and can pass water or flame-retardant gas into the metal rod and the connecting structure, thereby achieving better fire extinguishing and flame retardant effects.

[0005] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a fireproof rolling shutter door with flame retardant function, including a door frame, the top of the door frame is rotatably matched with a roller, a rolling shutter door body is installed in the door frame, and the rolling shutter door body includes multiple metal rods and multiple connecting structures, a fixed cloth is fixed on the metal rod at the top, the fixed cloth corresponds to the roller, the metal rod and the connecting structure are both hollow structures, a sliding rod is fixed on the lower side of the metal rod at the bottom, and the sliding rod corresponds to the door frame.

[0006] Furthermore, a slide groove is provided in the door frame, the slide groove corresponds to the slide rod, and door locks are installed at both ends of the slide rod.

[0007] Furthermore, a motor is fixed to one side of the door frame, and an output end of the motor is fixedly connected to the reel.

[0008] Furthermore, the fixing cloth is wound around the circumference of the reel, and one end of the fixing cloth is fixedly connected to the reel.

[0009] Furthermore, the connection structure is made of fireproof cloth, and the connection structure is fixed between two adjacent metal rods.

[0010] Furthermore, a first through slot is provided in the metal rod, a second through slot is provided in the connecting structure, and the first through slot is communicated with the second through slot.

[0011] Furthermore, a first through hole is formed on one side of the metal rod at the top, a second through hole is formed on one side of the metal rod at the bottom, a plug is installed in the second through hole, and an elastic cloth is installed on the other side of the metal rod at the bottom.

[0012] Furthermore, the surface of the metal rod is coated with a fireproof layer.

[0013] Beneficial effects of the utility model: The utility model is a fireproof rolling shutter door with flame retardant function, comprising a rolling shutter door body; a metal rod; a connecting structure; a sliding rod; and a door lock.

[0014] Dividing the rolling shutter door body into multiple metal rods and multiple connecting structures can reduce the overall weight of the rolling shutter door body, thereby facilitating winding. The metal rods and the connecting structures are set as hollow structures, so that water or flame-retardant gas can be passed through the metal rods and the connecting structures, thereby achieving better fire extinguishing and flame retardant effects. Installing door locks at both ends of the sliding rod can achieve better anti-theft effects. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a fireproof rolling shutter door with flame retardant function, comprising a door frame 1, wherein the top of the door frame 1 is rotatably matched with a reel 5, a rolling shutter door body 6 is installed in the door frame 1, and the rolling shutter door body 6 comprises a plurality of metal rods 8 and a plurality of connecting structures 9, a fixing cloth 7 is fixed on the metal rod 8 at the top, the fixing cloth 7 corresponds to the reel 5, the metal rod 8 and the connecting structure 9 are both hollow structures, a sliding rod 3 is fixed on the lower side of the metal rod 8 at the bottom, and the sliding rod 3 corresponds to the door frame 1.

[0022] In this embodiment, a slide groove 2 is opened in the door frame 1, the slide groove 2 corresponds to the slide rod 3, and door locks 15 are installed at both ends of the slide rod 3. A motor 4 is fixed to one side of the door frame 1, and the output end of the motor 4 is fixedly connected to the reel 5. The fixed cloth 7 is wound around the circumference of the reel 5, and one end of the fixed cloth 7 is fixedly connected to the reel 5.

[0023] Specifically, when the door needs to be closed, the motor 4 is started, so that the motor 4 drives the reel 5 to rotate, thereby loosening the shutter door body 6, and the shutter door body 6 can be pulled downward to unfold the shutter door body 6, and then locked by the door locks 15 at both ends, which can achieve the effect of closing the door to prevent theft.

[0024] The connecting structure 9 is made of fireproof cloth and is fixed between two adjacent metal rods 8.
