Technical Field

[0001] The utility model relates to the technical field of fire safety, in particular to a fireproof rolling shutter door. Background Art

[0002] Rolling shutters, like walls, serve as horizontal partitions and are typically installed where wall partitions are inconvenient. Conventional garage rolling shutters simply open and close, making it difficult to immediately isolate or control a fire near the shutters. This results in poor fire prevention effectiveness and makes existing rolling shutters less safe in the event of a fire. Summary of the Invention

[0003] The purpose of the utility model is to improve the problem that the existing fireproof rolling shutter door has poor timeliness in isolation or control when encountering a fire, and to provide a fireproof rolling shutter door.

[0004] The technical solutions to achieve the above objectives include the following:

[0005] Fire shutter doors, including:

[0006] A housing, a rolling shutter assembly, a temperature control sensor, a control circuit board, and a limit assembly. The rolling shutter assembly includes a rotating shaft, a fireproof cloth, a stopper, and a counterweight. The rotating shaft is rotatably installed in the housing. The first end of the fireproof cloth is fixed to the rotating shaft, and the counterweight is installed at the second end of the fireproof cloth.

[0007] The stopper is mounted on the rotating shaft, the limit assembly is fixed on the housing, and at least a portion of the limit assembly is used to cooperate with the stopper, and the control circuit board is electrically connected to the temperature control sensor and the limit assembly;

[0008] The limiting assembly has a first moving position and a second moving position. In the first moving position, the limiting assembly at least partially abuts against the stopper. In the second moving position, the limiting assembly is separated from the stopper.

[0009] In one embodiment, the limiting assembly includes a first driving member and a limiting member, the first driving member is installed in the housing, the limiting member is installed at the output end of the first driving member, and the first driving member is electrically connected to the temperature control sensor;

[0010] When the temperature control sensor senses that the temperature of the surrounding environment is greater than a preset threshold, the temperature control sensor generates an electrical signal, which is used to drive the first driving member to move the limiting member from the first moving position to the second moving position.

[0011] In one embodiment, the first driving member is an electric push rod, the limiting member is installed on the electric push rod, the length direction of the limiting member intersects with the length direction of the blocking member, and the limiting member is used to abut against the blocking member.

[0012] In one embodiment, the fire shutter door further comprises a second driving member, the second driving member is mounted on the housing, the first end of the rotating shaft is mounted on the output end of the second driving member, and the second end of the rotating shaft is rotatably connected to the housing;

[0013] The second driving member is electrically connected to the temperature control sensor, and the electrical signal of the temperature control sensor is used to drive the second driving member.

[0014] In one embodiment, the fireproof rolling shutter door further has a battery, which is installed in the housing and electrically connected to the first driving member, the second driving member, and the temperature control sensor.

[0015] In one embodiment, the fireproof rolling shutter door further includes a crank rod, which is installed at the second end of the rotating shaft. The crank rod is arranged outside the shell, and the crank rod is arranged opposite to the second driving member.

[0018] In one embodiment, the shell has an inner cavity. In a first position, the fireproof cloth is hidden in the inner cavity. In a second movable position, the fireproof cloth is exposed relative to the shell.

[0019] In one embodiment, the cross section of the shell is door-shaped, and the bottom of the shell has an opening, which is connected to the inner cavity.

[0020] The technical solution provided by the utility model has the following advantages and effects:

[0021] When a fire breaks out near a parking space, the temperature sensor senses a temperature rise near the space and generates an electrical signal, which drives the limit assembly from a first position to a second position. The limit assembly separates from the stopper, and the fireproofing fabric deploys under the weight of the counterweight, isolating the fire point inside and outside the parking space and controlling the spread of the fire, thus achieving a fire prevention effect. Furthermore, the temperature sensor automatically releases the limit on the rotating shaft, improving the timeliness of the fire shutter door and effectively preventing the spread of a car fire to other parking spaces.

[0031] In order to facilitate the understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0032] Unless otherwise specified or defined, the "first, second..." used in this article is only used to distinguish names and does not represent a specific quantity or order.

[0034] It should be noted that when an element is considered to be "fixed to" another element, it can be directly fixed to the other element or there can be an intermediate element; when an element is considered to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element; when an element is considered to be "mounted on" another element, it can be directly mounted on the other element or there can be an intermediate element. When an element is considered to be "located on" another element, it can be directly located on the other element or there can be an intermediate element.

[0035] The utility model proposes a fireproof rolling shutter door 100, such as Figures 1 to 3 As shown, it includes a shell 1, a roller shutter assembly 4, a temperature control sensor 2, a control circuit board, and a limit assembly 5. The roller shutter assembly 4 includes a rotating shaft 41, a fireproof cloth 42, a baffle 44, and a counterweight 43. The shell 1 is used to be installed on the ceiling 200 or the door frame. The rotating shaft 41 is rotatably installed in the shell 1. The first end of the fireproof cloth 42 is fixed to the rotating shaft 41, and the counterweight 43 is installed at the second end of the fireproof cloth 42; the baffle 44 is installed on the rotating shaft 41, the limit assembly 5 is fixed in the shell 1, and the limit assembly 5 is at least partially used to cooperate with the baffle 44. The control circuit board is electrically connected to the temperature control sensor 2 and the limit assembly 5 respectively; the limit assembly 5 has a first moving position and a second moving position. In the first moving position, the limit assembly 5 is at least partially against the baffle 44. In the second moving position, the limit assembly 5 is separated from the baffle 44.

[0036] Specifically, in the use scenario of this fire shutter door 100, Figure 5 As shown, fireproof rolling shutter doors 100 are installed on both sides of parking space 300. Under normal circumstances, the fireproof cloth 42 is retracted within the housing 1, and the stopper assembly 5 restrains the stopper 44. At this time, the stopper assembly 5 is in the first movable position, preventing the fireproof cloth 42 from expanding due to its own weight. When a fire occurs near parking space 300, the temperature control sensor 2 senses the temperature rise near the parking space. The temperature control sensor 2 generates an electrical signal, which drives the stopper assembly 5 through the control circuit of the control circuit board, causing the stopper assembly 5 to move from the first movable position to the second movable position. The stopper assembly 5 disengages from the stopper 44, and the fireproof cloth 42 expands due to the weight of the counterweight 43. This isolates the fire point inside and outside the parking space 300 and controls the spread of the fire, thus achieving a fire prevention effect. Furthermore, the temperature control sensor 2 can automatically release the limit on the rotating shaft 41, improving the timely operation of the fireproof rolling shutter door 100, effectively preventing the spread of the fire to other parking spaces 300.

[0037] It can be understood that the friction force of the rotation of the shaft 41 is small, and the fireproof cloth 42 is driven to unfold by the weight of the counterweight 43. Therefore, when the limiting component 5 is separated from the stopper 44, the fireproof cloth 42 can be automatically unfolded.

[0038] In one embodiment, Figure 4 and Figure 5 As shown, the limiting assembly 5 includes a first driving member 51 and a limiting member 52. The first driving member 51 is installed in the housing 1, and the limiting member 52 is installed at the output end of the first driving member 51. The first driving member 51 is electrically connected to the temperature control sensor 2. When the temperature control sensor 2 senses that the temperature of the surrounding environment is greater than a pre-threshold value, the temperature control sensor 2 generates an electrical signal, which is used to drive the first driving member 51 to move the limiting member 52 from the first moving position to the second moving position. Specifically, the first driving member 51 is used to drive the limiting member 52 to move, so that the limiting member 52 has a first moving position and a second moving position. When the fireproof cloth 42 is wrapped around the rotating shaft 41 and is in a contracted state, the first driving member 51 drives the limiting member 52 to move to the first moving position, so that the limiting member 52 is against the stopper 44. When the temperature control sensor 2 senses that the temperature of the surrounding environment is greater than the pre-threshold value, the temperature control sensor 2 generates an electrical signal to drive the first driving member 51, so that the limiting member 52 is moved from the first moving position to the second moving position.

[0039] Preferably, the first driving member 51 is an electric push rod, and the limiting member 52 is mounted on the electric push rod 51. The length direction of the limiting member 52 intersects with the length direction of the stopper 44, and the limiting member 52 is used to abut against the stopper 44. Specifically, the electric push rod 51 is used to drive the limiting member 52 to move, so that the limiting member 52 and the stopper 44 can be abutted. The length direction of the limiting member 52 intersects with the length direction of the stopper 44, so that the limiting member 52 can abut against the stopper 44 after movement.

[0040] In some embodiments, as Figure 2 As shown, the fireproof rolling shutter door 100 also has a second driving member 7, which is mounted on the housing 1. The first end of the rotating shaft 41 is mounted on the output end of the second driving member 7, and the second end of the rotating shaft 41 is rotatably connected to the housing 1. The second driving member 7 is electrically connected to the temperature control sensor 2, and the electrical signal of the temperature control sensor 2 is used to drive the second driving member 7. Specifically, when the temperature control sensor 2 senses that the temperature of the parking lot 300 is greater than a predetermined threshold value, the temperature control sensor 2 generates a first electrical signal, which is used to drive the first driving member 51, causing the first driving member 51 to drive the limiting member 52 to separate from the blocking member 44. At the same time, the first electrical signal is also used to drive the second driving member 7, causing the second driving member 7 to rotate the rotating shaft 41. During the forward rotation process, the rotating shaft 41 unfolds the fireproof cloth 42, thereby isolating the parking lot 300 and controlling the spread of fire. When the temperature control sensor 2 senses that the temperature of the parking lot 300 is lower than a preset threshold, the temperature control sensor 2 drives the second driving member 7 to drive the rotating shaft 41 to rotate in the opposite direction, so that the rotating shaft 41 retracts the fireproof cloth 42 .

[0041] In addition, if the friction force when the rotating shaft 41 rotates is large, the weight of the counterweight 43 cannot drive the fireproof cloth 42 to unfold. The second driving member 7 can be used to drive the rotating shaft 41 to rotate so that the fireproof cloth 42 can be smoothly unfolded, thereby improving the practicality of the fireproof rolling shutter door 100.

[0042] Preferably, Figure 4 and Figure 5 As shown, the fire shutter door 100 further includes a battery 6, which is installed in the housing 1 and is electrically connected to the first drive member 51, the second drive member 7, and the temperature control sensor 2. Specifically, the battery 6 is used to provide power to the first drive member 51, the second drive member 7, and the temperature control sensor 2, so that the first drive member 51, the second drive member 7, and the temperature control sensor 2 can operate normally.

[0043] Preferably, Figure 1 As shown, the fireproof rolling shutter door 100 further includes a crank lever 8 mounted on the second end of the rotating shaft 41. The crank lever 8 is disposed outside the housing 1 and is positioned opposite the second drive member 7. Specifically, if the second drive member 7 deploys the fireproof sheet 42, but a fire on one side of the sheet 42 is not promptly extinguished, the second drive member 7 may be damaged and rendered inoperable due to the high temperature on the side of the sheet 42. The crank lever 8 can then be used to rotate the rotating shaft 41, thereby retracting the sheet 42. In actual use, a ladder is required to operate the crank lever 8.

[0044] Preferably, the counterweight 43 is extended along the width direction of the fireproof cloth 42. Specifically, such an arrangement can reduce the height of the counterweight 43, so that the counterweight 43 is arranged along the width of the fireproof cloth 42, thereby improving the integrity of the counterweight 43 and the fireproof cloth 42 after connection.

[0045] Preferably, Figure 1 As shown, the fire shutter door 100 also includes at least two support plates 3, one of which is mounted on the first end of the housing 1, and the other is mounted on the second end of the housing 1. The support plates 3 have mounting holes 31 for screws to pass through, so that the support plates 3 are fixed to the ceiling 200 or door frame by screws. The support plates 3 are used to fix the housing 1 to the ceiling 200 or door frame, thereby improving the stability of the connection between the housing 1 and the ceiling 200.

[0046] Preferably, Figure 4As shown, the housing 1 has an inner cavity 11. In a first position, the fireproof cloth 42 is hidden in the inner cavity 11. In a second, movable position, the fireproof cloth 42 is exposed relative to the housing 1. Specifically, the housing 1 has a storage function. When the fireproof cloth 42 is wrapped around the rotating shaft 41 and retracted, it can be hidden and placed in the housing 1, preventing the fireproof cloth 42 from being exposed and being disturbed by the external environment when in the stored state, thereby improving the operational stability of the fireproof rolling shutter door 100. The cross-section of the housing 1 is in the shape of a door. The bottom of the housing 1 has an opening that is connected to the inner cavity 11. The housing 1 in the shape of a door is relatively easy to stamp and process.

[0047] Preferably, the protective cloth 42 is at least partially made of one of glass fiber, basalt fiber, asbestos, or any combination thereof. Specifically, glass fiber is one of the most common materials for fireproof cloths, and has the characteristics of high temperature resistance, corrosion resistance, and high strength. Glass fiber fireproof cloth is usually made of high temperature resistant, corrosion resistant, and high-strength glass fiber cloth, which is calendered or impregnated with silicone rubber and is suitable for environments between low temperatures of -70°C and high temperatures of 230°C. Basalt fiber is also one of the common fireproof materials, and has the characteristics of high temperature resistance, corrosion resistance, and high strength. Basalt fiber fireproof cloth performs well in high temperature environments and is suitable for various high temperature environments. Asbestos material has excellent fire resistance and is often used to make fireproof cloth 42. It can withstand high temperatures and prevent the spread of fire.
