Description

Technical Field

[0001] This utility model relates to the field of fireproof roller shutter technology, and in particular to a fireproof and heat-insulating inorganic super-grade roller shutter. Background Technology

[0002] Fire-resistant roller shutters are roller shutters that, together with their frames, can meet the requirements for fire resistance stability and integrity within a certain period of time. They consist of curtain panels, roller shafts, motors, guide rails, brackets, protective covers, and control mechanisms. Fire-resistant roller shutters are mainly used for fire-resistant partitions, especially firewalls and fire-resistant partitions, where large openings are required for production or use but fire doors cannot be installed.

[0003] In a fire, not only high temperatures pose a threat to human health, but also dense smoke poses various other dangers, including oxygen deficiency, poisoning, respiratory damage, suffocation, eye irritation, and skin damage. Existing equipment is usually equipped with sealing strips for sealing purposes, but the high temperatures during a fire can easily deform these strips, allowing dense smoke to easily escape through the sides of the roller shutter, resulting in poor protective performance. Utility Model Content

[0004] The purpose of this utility model is to provide a fireproof and heat-insulating inorganic super-grade roller shutter door to solve the above-mentioned problems.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides a fireproof and heat-insulating inorganic super-grade roller shutter door, including a door frame, a transmission box and a fireproof door curtain. The door frame is fixedly installed below the transmission box, and a motor is fixedly installed inside the transmission box. The motor drive end is connected to a roller, and the left and right ends of the fireproof door curtain are embedded in the door frame.

[0007] In the above technical solution, the fireproof door curtain is embedded in the door frame and moves up and down along it, which increases the stability of the fireproof door curtain, reduces the contact area between the two ends of the fireproof door curtain and the outside, and prevents deformation caused by high temperature.

[0008] The door frame is provided with a connecting rod, and the door frame is provided with a sliding groove. A sealing block is provided in the sliding groove. The connecting rod is threaded to the door frame, and the connecting rod is movably connected to the sealing block through a bearing. The sealing block is provided in two sets, located at the left and right ends of the fireproof door curtain respectively.

[0009] In the above technical solution, after the fireproof door curtain is lowered, the connecting rod is rotated to push the sealing block to move and contact the fireproof door curtain, and push the fireproof door curtain to fit tightly against the door frame. The sealing block is provided on both sides at the left and right ends of the fireproof door curtain to reduce the spread of dense smoke generated by the fire through the sides of the fireproof door curtain.

[0010] In one embodiment, the end of the roller furthest from the motor is movably mounted on the transmission box via a bearing. This technical solution reduces the friction and energy loss of the roller while improving transmission accuracy and stability.

[0011] In one embodiment, the slide and the door frame are an integrated structure. In this technical solution, the slide restricts the sealing block, allowing it to move back and forth along the slide.

[0012] In one embodiment, the sealing block has an L-shaped structure, and the fireproof door curtain uses steel material as the clamp and inorganic fiber material as the curtain surface. The left and right ends of the fireproof door curtain are adapted and fitted with the sealing block. In this technical solution, by setting two sealing blocks symmetrically distributed on the left and right sides of the fireproof door curtain, they can fit with the fireproof door curtain through their L-shaped structure during use and push them to fit with the door frame, reducing gaps and improving the sealing effect.

[0013] In one embodiment, the connecting rod passes through the door frame and the slide groove and connects to the sealing block. By rotating the connecting rod, the sealing block is moved back and forth along the slide groove. In this technical solution, the sealing block can be moved back and forth along the slide groove by the connecting rod, which is simple and convenient to operate.

[0014] In one embodiment, connecting rods are installed on both sides of the door frame. In this technical solution, connecting rods are set on both sides of the door frame to control the sealing blocks, which effectively improves the sealing effect.

[0015] The advantages or beneficial effects of the above technical solutions include at least the following:

[0016] This utility model discloses a fireproof and heat-insulating inorganic super-grade roller shutter door. The fireproof door curtain is embedded in the door frame and moves up and down along it, which increases the stability of the fireproof door curtain, reduces the contact area between the two ends of the fireproof door curtain and the outside, and prevents deformation caused by high temperature.

[0017] Meanwhile, after the fireproof door curtain is lowered, the connecting rod is rotated to push the sealing block to move and contact the fireproof door curtain, and push the fireproof door curtain to fit tightly against the door frame. The sealing block is located on both sides of the fireproof door curtain to reduce the spread of dense smoke generated by a fire through both sides of the fireproof door curtain.
