The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a composite steel fireproof rolling shutter door, including a fireproof rolling shutter door body 1. The fireproof rolling shutter door body 1 has a rectangular opening 10, and multiple baffles 2 are provided in the rectangular opening 10 to block the rectangular opening 10. The opposite ends of the baffles 2 protrude to form connecting parts, and the connecting parts are abutted against each other. The other ends of the baffles 2 extend to the inner side of the fireproof rolling shutter door body 1 and are slidably connected to the fireproof rolling shutter door body 1. The inner side of the connecting parts is provided with grooves, and adjacent grooves are combined to form U-shaped grooves. The vertically opposite U-shaped grooves are combined to form a channel. Half rods 7 are installed on the grooves, and adjacent half rods 7 are combined to form positioning posts. A fixing component is provided in the channel to press the multiple positioning posts inward.

[0023] In this embodiment, the fixing component includes a rubber band 5 and multiple fixing rings 9. The rubber band 5 is provided with multiple fixing holes, and the fixing rings 9 are all installed in the fixing holes. The rubber band 5 is vertically arranged in the channel, and the fixing rings 9 are all sleeved on the outside of the positioning post. The outer side of the half rod 7 protrudes to form a positioning part 8, and the outer ring surface of the positioning part 8 is in contact with the end face of the positioning ring.

[0024] In this embodiment, the fireproof rolling shutter door body 1 is composed of multiple steel fireproof plates, and the interior of each steel fireproof plate is hollow and filled with fireproof and heat-insulating material. Each steel fireproof plate located on both sides of the baffle 2 is provided with a sliding groove 3, and a slider 12 is slidably installed in each sliding groove 3. The slider 12 is fixedly connected to the baffle 2, and a compression spring 4 is installed between the slider 12 and the sliding groove 3.

[0025] The baffle is made of steel fireproof board and has a fireproof and heat-insulating material inside to ensure fireproof effect.

[0026] In this embodiment, both the slider 12 and the slide groove 3 have trapezoidal cross sections, and the compression springs 4 are in a stretched state. The slider and the slide groove can position the baffle, preventing the baffle from detaching from the steel fireproof plate.

[0027] In this embodiment, slots 14 are provided on one side of the connecting part, and inserts 13 are protruding on the other side of the connecting part. The inserts 13 are inserted into the corresponding slots 14. The connection stability between the baffles is increased by the inserts and slots, and misalignment at the connection is avoided.

[0028] In this embodiment, the positioning parts 8 are all made of heat-resistant plastic, and the positioning parts 8 are all set in a hemispherical structure. The plastic has a certain degree of flexibility, so when the fixing ring is pulled outward, it can squeeze the positioning part, so that the fixing ring can be separated from the half rod.

[0029] In this embodiment, the fixing ring 9 is made of metal, while the rubber band 5 is made of heat-resistant rubber. The fixing ring can fully compress the half rod inward, allowing the baffles to close and blocking the rectangular opening. The heat-resistant rubber prevents the rubber band from burning, thus allowing the fixing ring to be quickly removed from the positioning post.

[0030] In the event of a fire, the fireproof rolling shutter door can be closed immediately. If there are people inside, the rubber belt can be pulled outwards. The movement of the rubber belt moves the fixing ring until it disengages from the positioning post through the positioning part. After the fixing ring is no longer in place, the rebound of the compression spring can simultaneously pull the baffle outwards, allowing the baffle to move outwards along the slide rail until the rectangular opening is opened, enabling people inside to escape smoothly through the rectangular opening. Moreover, this operation does not require the use of electricity and can still be used after a power outage, thus greatly increasing the safety of the fireproof rolling shutter door and better meeting social needs.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
