Description

Technical Field

[0001] This application relates to the field of fireproof roller shutter technology, and in particular to a fireproof roller shutter baffle limiting structure. Background Technology

[0002] In the field of building fire safety, the development of fire prevention facilities has always been a crucial aspect of protecting people's lives and property. With the continuous advancement of the construction industry, various high-rise buildings and large shopping malls are constantly emerging, leading to an increasing demand for fire separation and protection. Fire-resistant roller shutters, as an important fire separation facility, can effectively prevent the spread of fire in the event of a fire, buying valuable time for evacuation and fire rescue, and playing a key role in reducing fire losses.

[0003] In traditional fire-resistant roller shutter applications, various technical methods are commonly used to ensure normal operation and a certain degree of limitation. Some employ simple track systems, where the fire-resistant roller shutter slides up and down along fixed tracks installed on the wall, thus ensuring its movement within a certain range. These tracks are typically made of metal, possessing a certain degree of strength and stability. Others utilize manually operated limit devices, where the roller shutter is manually locked after descending to a certain position to restrict further movement. Additionally, some systems use simple sensors and control devices; when the fire-resistant roller shutter reaches a preset position, a signal is sent to stop the drive mechanism, thereby achieving the limit function. These methods, to a certain extent, meet the basic requirements for fire-resistant roller shutter use and have been widely used in various building applications for a long time.

[0004] However, while traditional track systems can ensure the sliding of fireproof roller shutters, they lack effective limiting measures, making it difficult to accurately control the descent position of the fireproof roller shutters. This can easily lead to situations where the fireproof roller shutters slide too far or not to the correct position. Manually operated limiting devices are not only inefficient but may also fail to function in time in emergencies. Furthermore, simple sensors and control devices have poor reliability, and once they malfunction, they cannot accurately perform the limiting function. As a result, the fireproof roller shutters cannot accurately block the spread of fire when a fire occurs, posing a significant safety hazard. Utility Model Content

[0005] To address the problems of traditional fireproof roller shutters lacking effective limiting during sliding, making it difficult to accurately control the descent of the fireproof roller shutter, resulting in excessive or insufficient descent, as well as the low efficiency of manual operation limiting and its inability to function promptly in emergencies, this application provides a fireproof roller shutter baffle limiting structure.

[0006] The fireproof roller shutter baffle limiting structure provided in this application adopts the following technical solution: A fireproof roller shutter baffle limiting structure includes a housing, a guide rail installed at the bottom of the housing, a fireproof roller shutter slidably arranged on the guide rail, and a limiting mechanism installed on the fireproof roller shutter. The housing is provided with a driving mechanism for driving the fireproof roller shutter to move along the guide rail. The limiting mechanism includes an assembly sliding on the guide rail and limiting members installed on the side of the assembly away from the fireproof roller shutter. The assembly is installed on the fireproof roller shutter, and the cross-sectional spacing of the limiting members is greater than the spacing of the parallel guide rails.

[0007] By adopting the above technical solution, the limiting mechanism is installed on the fireproof roller shutter. The components of the limiting mechanism can slide along the guide rail, which can ensure that the fireproof roller shutter moves smoothly along the guide rail. Since the cross-sectional spacing of the limiting components is greater than the spacing of the parallel guide rails, when the fireproof roller shutter moves to a certain position, the limiting components will contact and block the end of the guide rail, preventing the fireproof roller shutter from slipping off the guide rail and effectively limiting the movement range of the fireproof roller shutter. At the same time, the drive mechanism inside the housing can drive the fireproof roller shutter to move along the guide rail direction, realizing the automated control of the fireproof roller shutter.

[0008] Optionally, the assembly includes a guide plate that slides on a guide rail, a sealing plate covering the guide plate, a first locking part and a second locking part, wherein the first locking part is used to lock the fireproof roller shutter and the guide plate, and the second locking part is used to lock the limiting member and the guide plate.

[0009] By adopting the above technical solution, the guide plate allows the components to slide on the guide rail, and the sealing plate covering the guide plate can protect the guide plate; the first locking part can firmly connect the fireproof roller shutter and the guide plate, ensuring that the fireproof roller shutter and the components move synchronously; the second locking part can reliably connect the limiting part and the guide plate, ensuring the overall structural stability of the limiting mechanism; making the connection between the limiting mechanism and the fireproof roller shutter more stable, and better realizing the limiting function of the fireproof roller shutter.

[0010] Optionally, the first locking part includes a locking bolt and a locking nut, wherein the locking bolt passes through the sealing plate, the fireproof roller shutter and the locking nut in sequence for threaded engagement.

[0011] By adopting the above technical solution, the fireproof roller shutter and guide plate are effectively locked together, facilitating disassembly and installation.

[0012] Optionally, the limiting component includes a galvanized square steel plate installed on the sealing plate, a limiting plate installed on the galvanized square steel plate, and a spring connection between the galvanized square steel plate and the limiting plate. A reinforcing plate is installed on the outer surface of the galvanized square steel plate and the aluminum plate, and the cross-section of the limiting plate is larger than the cross-section of the galvanized square steel plate.

[0013] By adopting the above technical solution, the cross-section of the limiting plate is larger than that of the galvanized square steel, which can drive the fireproof roller shutter to move along the guide rail and effectively limit the fireproof roller shutter. The installation of the accessories can firmly install the limiting components and the fireproof roller shutter. The spring connecting the galvanized square steel and the limiting plate in the limiting components, the installation of the reinforcing plate, and the larger cross-section of the limiting plate can enhance the stability and reliability of the limiting.

[0014] Optionally, the limiting plate is a gypsum board or an aluminum plate.

[0015] By adopting the above technical solutions, the limiting plate can be made of gypsum board or aluminum plate, which can utilize the fire resistance of gypsum board or the strength and corrosion resistance of aluminum plate to improve the fire resistance and durability of the fireproof roller shutter baffle limiting structure.

[0016] Optionally, the second locking part includes a first locking screw and a second locking screw. The first locking screw passes through the reinforcing plate, the sealing plate and the guide plate in sequence and is threaded together. The second locking screw passes through the galvanized square steel, the sealing plate and the guide plate in sequence and is threaded together.

[0017] By adopting the above technical solution, the limiting component and the guide plate of the assembly are firmly connected together, ensuring the stability and reliability of the limiting mechanism.

[0018] Optionally, the outer surface of the fireproof roller shutter is coated with a fireproof layer.

[0019] By adopting the above technical solution, coating the outer surface of the fireproof roller shutter with a fireproof layer can enhance the fireproof capability of the fireproof roller shutter and improve the fireproof performance of the fireproof roller shutter baffle limiting structure.

[0020] Optionally, the drive mechanism includes a drive motor installed inside the housing, a shaft mounted on the drive motor, a sprocket mounted on the shaft, and a chain that drives between adjacent sprockets. The end of the fireproof roller shutter furthest from the mounting parts is driven on the shaft.

[0021] By adopting the above technical solution, the drive motor drives the rotating shaft to rotate, and the sprocket rotates with the rotating shaft and is driven by the chain, thereby realizing the movement of the fireproof roller shutter along the guide rail direction, and can automatically control the opening and closing of the fireproof roller shutter.

[0022] Optionally, the guide rail extends outward from one end near the housing.

[0023] By adopting the above technical solution, the fireproof roller shutter can enter the guide rail closer to the shell more smoothly during the lifting process, avoiding jamming. This facilitates the fireproof roller shutter being stored in the shell, reduces damage caused by collision and friction between the fireproof roller shutter and the end of the guide rail, and extends its service life.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The limiting mechanism prevents the fireproof roller shutter from sliding too far or too far, and can precisely control the descent position of the fireproof roller shutter; 2. The limit mechanism automates the limit setting, which is more efficient than manual limit setting and can play a timely role in emergency situations; 3. The fireproof roller shutter is coated with a fireproof layer on its outer surface, which improves its fire resistance and better prevents the spread of fire. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a fireproof roller shutter baffle limiting structure.

[0032] Reference Figure 1The device includes a housing 1, a guide rail 2, a fireproof roller shutter 3, a limiting mechanism 4, and a driving mechanism 5. The guide rail 2 is installed at the bottom of the housing 1, and the fireproof roller shutter 3 is slidably arranged on the guide rail 2. The limiting mechanism 4 is installed on the fireproof roller shutter 3, and the driving mechanism 5 is located inside the housing 1 to drive the fireproof roller shutter 3 to move along the guide rail 2. The fireproof roller shutter 3 can move along the guide rail 2 under the action of the driving mechanism 5, and the limiting mechanism 4 can accurately control its position to avoid excessive or insufficient sliding, effectively improving the safety of the fireproof roller shutter 3.

[0033] See Figure 2 and Figure 3 As shown, the limiting mechanism 4 includes an assembly 41 and a limiting member 42. The assembly 41 slides on the guide rail 2 and is installed on the fireproof roller shutter 3. The limiting member 42 is installed on the side of the assembly 41 away from the fireproof roller shutter 3, and the cross-sectional spacing of the limiting member 42 is greater than the spacing of the parallel guide rails 2.

[0034] See Figure 2 As shown, the assembly 41 includes a guide plate 411, a sealing plate 412, a first locking part 413, and a second locking part 414. The guide plate 411 is elongated and its end is adapted to the shape of the guide rail 2, allowing it to slide smoothly on the guide rail 2. The sealing plate 412 covers the guide plate 411, providing protection and sealing. It is usually made of steel plate with a moderate thickness, ensuring sufficient strength without being too heavy. The sealing plate 412 can be fixed to the guide plate 411 by welding or bolting. The first locking part 413 is used to lock the fireproof roller shutter 3 and the guide plate 411. It includes a locking bolt 4131 and a locking nut. The locking bolt 4131 passes through the sealing plate 412 and the fireproof roller shutter 3 and engages with the locking nut through a threaded connection. Tightening the locking nut will firmly fix the fireproof roller shutter 3 to the guide plate 411. The second locking part 414 is used to lock the limiting member 42 and the guide plate 411.

[0035] See Figure 3As shown, the limiting component 42 includes a galvanized square steel 421, a limiting plate 422, and a spring 423 connecting them. The galvanized square steel 421 has good corrosion resistance. The cross-section of the limiting plate 422 is larger than that of the galvanized square steel 421. It can be made of gypsum board or aluminum plate. Gypsum board has good fire resistance and is lightweight; aluminum plate has high strength and is corrosion resistant. The spring 423 can generate elastic deformation when the limiting plate 422 is subjected to external force to mitigate the impact on the limiting plate 422. A reinforcing plate 424 is installed on the outer surface of the galvanized square steel 421 and the aluminum plate. The reinforcing plate 424 is usually made of steel plate and is installed by welding or bolting to enhance the overall strength of the limiting component 42. The second locking part 414 includes a first locking screw 4141 and a second locking screw 4142. The first locking screw 4141 passes through the reinforcing plate 424, the sealing plate 412 and the guide plate 411 in sequence and is threaded. The second locking screw 4142 passes through the galvanized square steel 421, the sealing plate 412 and the guide plate 411 in sequence and is threaded. The limiting member 42 is firmly installed on the guide plate 411 by these two locking screws.

[0036] See Figure 1 As shown, the drive mechanism 5 includes a drive motor, a rotating shaft, a sprocket, and a chain. The drive mechanism 5 is a conventional technology and its structure is not shown in the attached diagram. The drive motor is installed inside the housing 1, providing power for the movement of the fireproof roller shutter 3. The rotating shaft is mounted on the output shaft of the drive motor, and the sprocket is mounted on the rotating shaft. Adjacent sprockets are connected by a chain drive. The chain has a certain pitch and tensile strength to ensure the accuracy and reliability of the transmission. The end of the fireproof roller shutter 3 furthest from the mounting part 41 is driven onto the rotating shaft. When the drive motor rotates, it drives the rotating shaft to rotate through the sprocket and chain, thereby moving the fireproof roller shutter 3 along the guide rail 2.

[0037] See Figure 1 As shown, the guide rail 2 extends outward from the end near the housing 1, which facilitates the fireproof roller shutter 3 to move more smoothly in and out of the guide rail 2 during the rising and falling process, reducing jamming.

[0038] The implementation principle of the fireproof roller shutter baffle limiting structure in this embodiment is as follows: In actual use, when an emergency such as a fire occurs, the drive mechanism 5 is activated, the drive motor drives the rotating shaft to rotate, and through the transmission of the sprocket and chain, the fireproof roller shutter 3 descends along the guide rail 2. The limiting mechanism 4 moves together with the fireproof roller shutter 3. When the limiting member 42 touches a specific position, because its cross-sectional spacing is greater than the spacing of the guide rail 2, it will play a blocking role, accurately limiting the descent position of the fireproof roller shutter 3. The assembly 41 firmly connects the fireproof roller shutter 3 and the limiting member 42 together through the first locking part 413 and the second locking part 414, ensuring the reliability of the limiting function. Compared with the traditional limiting method of the fireproof roller shutter 3, this embodiment can more accurately control the position of the fireproof roller shutter 3, avoid the problem of excessive or insufficient descent, greatly improve the ability of the fireproof roller shutter 3 to block the spread of fire when a fire occurs, and effectively protect the safety of people's lives and property.
