Description

Technical Field

[0001] This utility model relates to the field of fireproof rolling shutter door technology, specifically a structurally stable fireproof rolling shutter door. Background Technology

[0002] With the rapid development of technology, roller shutter doors have become increasingly advanced in structure and more comprehensive in function, providing functions such as heat preservation, dust prevention, windproofing, sound insulation, and odor prevention.

[0003] Utility Model Patent Application Publication in China CN214787124U The specification discloses a structurally stable fireproof rolling shutter door. The technical solution includes a rolling shutter door box, a motor fixedly connected to one side of the box, two door frames fixedly connected to the bottom of the box, a fixing mechanism inside the box, and a protective component outside the motor. The fixing mechanism includes a first rotating shaft fixedly connected to the motor output end. The advantages of this structurally stable fireproof rolling shutter door are: by the user operating the motor to rotate forward, the motor causes the rollers to rotate, thus lowering the rolling shutter door body. The forward rotation of the motor also drives the bearing seat to move, allowing the first baffle to move left and right. The forward rotation of the motor can also drive multiple rotating rods to rotate, thus rotating the second baffle. This invention increases the service life of the rolling shutter door and reduces noise caused by shaking, bringing benefits to people's daily lives. However, this device does not solve the problem of easily isolating fire sources twice. Therefore, we propose a structurally stable fireproof rolling shutter door. Utility Model Content

[0004] The purpose of this utility model is to provide a structurally stable fireproof rolling shutter door to solve the problem mentioned in the background art that it is not possible to easily isolate the fire source twice.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A structurally stable fireproof roller shutter door includes a fixed wall and an installation ground. The installation ground is fixedly installed at the bottom of the fixed wall. A main structure is fixedly installed inside the fixed wall. A control mechanism is fixedly installed on the surface of the fixed wall. The main structure includes two U-shaped vertical steel bars, a first roller shutter storage box, and a second roller shutter storage box. Two U-shaped vertical steel bars are fixedly installed inside the fixed wall. The first roller shutter storage box is fixedly installed on the top of the two U-shaped vertical steel bars. The second roller shutter storage box is fixedly installed on one side of the first roller shutter storage box.

[0007] Preferably, the two U-shaped vertical steels are filled with waterproof foam adhesive, and two sets of limiting grooves are provided on the side of the two U-shaped vertical steels away from the foam adhesive filling. Two T-shaped brackets are evenly fixed at the bottom of the two U-shaped vertical steels. The two T-shaped brackets are fixed to the top of the fixed ground by expansion bolts. The two T-shaped brackets are hollow load-bearing components, and the bottom of the two U-shaped vertical steels penetrates into the two T-shaped brackets, which is conducive to better fixing the flexible roller shutter panel through the limiting grooves.

[0008] Preferably, both the first and second roller blind storage boxes are equipped with two fixed lifting motors. Each of the two lifting motors has two sets of supporting shafts movably mounted at its output end. Each of the two sets of supporting shafts has two supporting columns movably mounted in the middle. Each of the two supporting columns has two sets of flexible roller blind panels movably mounted on its surface. The flexible roller blind panels are made of Z-shaped aluminum alloy or stainless steel. Each of the two sets of flexible roller blind panels has a fireproof cloth fixedly mounted in the middle. The fireproof cloth is made of inorganic fiber composite material. When the user pulls the protective door, it moves horizontally through the limiting pulley in the limiting groove at the top of the installation ground. When the user controls this Q to divide the space, the two lifting motors inside the first and second roller blind storage boxes rotate, causing the supporting shafts and supporting columns to rotate. At this time, the limiting sliders on both sides of the flexible roller blind panels will descend inside the limiting groove on the inner side of the U-shaped vertical steel until the bottom of the flexible roller blind panel contacts the ground.

[0009] Preferably, two sets of limiting sliders are fixedly provided on both sides of the two sets of flexible roller shutter panels, and the two sets of flexible roller shutter panels are fixed by limiting the limiting slider groove.

[0010] Preferably, the top of the fixed ground at the bottom of the two sets of flexible roller shutter panels is limited. In the event of a fire, the two layers of flexible roller shutter panels and the fireproof cloth inside the flexible roller shutter panels will provide the first layer of fireproofing. A protective door is movably installed at the top of the limiting groove. Several limiting pulleys are movably installed at the bottom of the protective door. Two ceramic layers are fixedly installed inside the protective door. A fireproof adhesive layer is fixedly installed in the middle of the two ceramic layers. The fireproof adhesive layer is made of micro-nano aerogel. A protective rock wool layer is fixedly installed in the middle of the fireproof adhesive layer. Then, the two ceramic layers, the fireproof adhesive layer and the protective rock wool layer are bonded together inside the protective door to protect the fire source.

[0011] Preferably, the control mechanism includes a control box and a control screen. The control screen is fixedly mounted on the surface of the control box, and a control button group is fixedly mounted on one side of the control screen. The control box, control screen, control button group, and drive structure of the main mechanism are electrically connected. The control box is programmed with a fireproof rolling shutter door control program, which facilitates better control of Q through the control mechanism.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This structurally stable fireproof roller shutter door allows the user to first pull the protective door, which then moves horizontally along the limiting groove at the top of the installation ground via limiting pulleys. When the user controls the door to divide the space, two lifting motors inside the first and second roller shutter storage boxes rotate, driving the support shaft and support column to rotate. At this time, the limiting sliders on both sides of the flexible roller shutter panel descend within the limiting groove on the inner side of the U-shaped vertical steel until the bottom of the flexible roller shutter panel contacts the ground. In the event of a fire, the two layers of flexible roller shutter panels and the fireproof cloth inside the flexible roller shutter panels will provide the first layer of fireproofing. Subsequently, the combination design of two ceramic layers bonded together inside the protective door to isolate the fire source achieves the purpose of the door easily isolating the fire source twice.

[0014] 2. This structurally stable fireproof rolling shutter door achieves the purpose of easy control through a control mechanism. Attached Figure Description
