Description

Technical Field

[0001] This utility model relates to the field of fireproof roller shutter doors, specifically a fireproof roller shutter door body for garages. Background Technology

[0002] Roller shutters are doors made of multiple articulated, movable sections connected together. They rotate up and down around a central axis at the top of the door within a fixed track. Roller shutters are suitable for commercial storefronts, garages, shopping malls, hospitals, factories, mines, and other public places or residences. They are especially useful for places with large doorways where it is inconvenient to install ground-level doors, providing a convenient and quick way to open the door.

[0003] While existing fire-resistant roller shutters can effectively prevent the spread of fire in most cases, their fire resistance is generally limited. Furthermore, their large size and predominantly metal construction make them inconvenient to operate, reducing their practicality. Therefore, we propose a fire-resistant roller shutter door for garages. Utility Model Content

[0004] In view of the shortcomings of existing roller shutter doors, such as their generally poor fire resistance and the inconvenience of retracting and extending the door panels due to their large size and mostly metal door panels, this utility model provides a garage roller shutter fireproof door body that effectively improves the overall fire resistance of the device, while also facilitating the quick rolling of the connecting rods and fireproof curtains, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A garage roller shutter fireproof door body includes multiple equidistant connecting rods, adjacent connecting rods are rotatably connected by multiple brackets, and fireproof curtains are connected to both sides of the connecting rods. The sides of the fireproof curtains are fastened to the ends of the connecting rods by a locking mechanism. The locking mechanism includes an end plate, and side plates are symmetrically connected to both sides of the end plate. The fireproof curtains are located between the two side plates, and the end plate is connected to the ends of the connecting rods by a first bolt. Threaded tubes are symmetrically connected to the outer wall of the connecting rods, and a second bolt is connected to the side plate. The other end of the second bolt passes through the fireproof curtain and is fixedly connected to the threaded tube.

[0006] Optionally, the bracket includes a connecting plate, with sleeves tightly fitted at both ends of the connecting plate, and the two sleeves are coaxially connected to connecting rods located on both sides of the connecting plate.

[0007] Optionally, the connecting plates between adjacent connecting rods are staggered.

[0008] Optionally, mounting holes are provided on the side plate, and the second bolt is coaxially connected to the mounting holes.

[0009] Optional, the end plates and side plates are integrated into one structure.

[0010] Optionally, the end plates and side plates are made of high-temperature resistant boards.

[0011] Optionally, the fireproof curtain is an inorganic composite fireproof roller shutter.

[0012] Compared with the prior art, this utility model achieves a stable connection between the fireproof curtain and the connecting rod, and multiple connecting plates can stably connect adjacent connecting rods. This not only effectively improves the overall stability of the device, but also ensures stable winding of the connecting rod and the fireproof curtain, thereby effectively improving the overall fireproof function of the device.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 5 The present invention provides a technical solution: a garage roller shutter fireproof door body, comprising multiple equidistantly arranged connecting rods 11, adjacent connecting rods 11 being rotatably connected by multiple brackets, wherein the brackets include connecting plates 13, and sleeves 12 are tightly fitted to both ends of the connecting plates 13, the two sleeves 12 being coaxially connected to the connecting rods 11 located on both sides of the connecting plates 13, and the connecting plates 13 between adjacent connecting rods 11 being staggered, such as... Figure 3 , 4 As shown, when the door is rotated, the sleeve 12 and the connecting rod 11 are rotatably connected, which ensures normal winding during storage. Furthermore, the connection of multiple connecting plates 13 can effectively improve the overall stability of the device.

[0022] like Figure 3 , 4 As shown in Figure 5, fire curtains 6 are connected to both sides of the connecting rod 11. In actual use, the fire curtain 6 is an inorganic composite fireproof roller shutter, which has the properties of long fire resistance time and strong heat radiation resistance. In actual use, smoke detectors and heat detectors can be installed inside the fire curtain 6 and linked with the automatic fire alarm system. This not only effectively realizes the fire prevention function, but also reduces the load on the building, making its safety more reliable.

[0023] In summary, when in use, the fireproof curtain 6 is secured to the end of the connecting rod 11 via a locking mechanism. The locking mechanism includes an end plate 4, with side plates 8 symmetrically connected to both sides of the end plate 4. The fireproof curtain 6 is located between the two side plates 8. The end plate 4 is connected to the end of the connecting rod 11 via a first bolt 5. The end plate 4 and the side plates 8 are an integrated structure, and both the end plate 4 and the side plates 8 are made of high-temperature resistant plates. This allows for a stable connection between the fireproof curtain 6 and the connecting rod 11, and ensures stable rolling of the connecting rod 11 and the fireproof curtain 6, while effectively achieving the fireproof function.

[0024] like Figure 4 , 5 As shown, in order to improve the stability of the fire curtain 6 installation, threaded pipes 14 are symmetrically connected to the outer wall of the connecting rod 11. A second bolt 7 is connected to the side plate 8. The other end of the second bolt 7 passes through the fire curtain 6 and is fixedly connected to the threaded pipe 14. An installation hole 10 is opened on the side plate 8, and the second bolt 7 is coaxially connected to the installation hole 10.

[0025] like Figure 1 , 2As shown, it should be noted that this utility model needs to be connected with the mounting cover 1 installed on the garage door opening. Since the mounting cover 1 has a connecting shaft 9 driven by the motor 2, in use, the end of the fireproof curtain 6 is fixedly connected to the connecting shaft 9, and the other end of the fireproof curtain 6 extends out from the opening 3 at the bottom of the mounting cover 1 to seal the garage door opening.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
