Description

Technical Field

[0001] The utility model relates to the technical field of fireproof rolling curtains, in particular to an inorganic cloth fireproof rolling curtain. Background Art

[0002] Inorganic cloth fireproof roller shutter is a special fireproof roller shutter. Its curtain fabric is made of non-metallic materials after special treatment and has fireproof, smokeproof and heat insulation functions. It is an inorganic material roller shutter, mainly made of inorganic fireproof fiber after special processing, with the characteristics of low bulk density, resistance to thermal vibration, fire protection, dust removal, and easy construction. The curtain surface thickness of the inorganic cloth fireproof roller shutter is small, the space occupied is small, and the weight per square meter is no more than 5kg, which is one-fifth of the weight of the steel fireproof roller shutter. In addition, it does not require water curtain maintenance, reduces the amount of water used for fire fighting, and can also close the fire area in case of fire. The function of the smoke barrier wall of the inorganic cloth fireproof roller shutter is to prevent the continued spread of smoke.

[0003] Inorganic fabric fireproof rolling shutters can prevent fire from spreading from door and window openings. Inorganic fabric fireproof rolling shutters are low in cost, light in weight, and have good fireproof performance, and are widely used. However, existing inorganic fabric fireproof rolling shutters are still relatively thin and have low stability. When they are impacted by high-temperature heat waves, if the heat wave impact is more severe, the inorganic fabric fireproof rolling shutter will be greatly impacted, which will destroy its stability and cause damage, thereby reducing its fireproof effect.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 An inorganic cloth fireproof roller shutter comprises a roller shutter chassis 1, a roller shutter chassis 1 having a reel 61 which is rotated by a first driving motor 6, a roller shutter body 2 is fixedly arranged on the reel 61, and one end of the roller shutter body 2 extends from the bottom of the roller shutter chassis 1; both sides of the roller shutter chassis 1 are provided with vertical guide rails 3 extending downward, the vertical guide rails 3 are adapted to be arranged on both sides of the roller shutter body 2, the bottoms of the vertical guide rails 3 are connected to a bottom plate 5, and reinforcing columns 4 are movably arranged in front of the vertical guide rails 3 on both sides.

[0022] Among them, a transverse guide rail 51 and a rolling shutter groove 52 are transversely opened on the bottom plate 5, the transverse guide rail 51 is arranged corresponding to the reinforcement column 4, and the rolling shutter groove 52 is arranged corresponding to the bottom of the rolling shutter body 2. The bottom of the rolling shutter body 2 can be stored and clamped by the arrangement of the rolling shutter groove 52, and the bottoms of the reinforcement columns 4 on both sides are located on the transverse guide rail 51 for movement.

[0023] The bottom of the two side reinforcing columns 4 is arranged in the transverse guide rail 51, and the top extends into the interior of the rolling shutter machine box 1. The two side reinforcing columns 4 are usually located in front of the two side vertical guide rails 3. When the rolling shutter body 2 is lowered, the two side reinforcing columns 4 move to the bottom of the rolling shutter body 2.

[0024] Among them, a second drive motor 7 is arranged on one side of the first drive motor 6, and a bidirectional screw rod 71 is arranged on the output end of the second drive motor 7. Screw rod pairs 8 are arranged at both ends of the bidirectional screw rod 71, and the screw rod pairs 8 are connected to the top of the reinforcing column 4. When the bidirectional screw rod 71 rotates, the screw rod pair 8 is located on the bidirectional screw rod 71 and moves. Through the setting of the second drive motor 7, the bidirectional screw rod 71 can be rotated, so that the screw rod pair 8 is driven to move by the rotation of the second screw rod 71, so that the reinforcing column 4 can be driven to move by the movement of the screw rod pair 8. And the reinforcing columns 4 on both sides are located in front of the rolling shutter body 2 to prevent the fire behind the rolling shutter body 2.

[0025] The rolling shutter housing 1 is connected to the wall, and the vertical guide rails 3 and the bottom plate 5 are embedded in the wall. In this way, the rolling shutter body 2 can be installed in the opening between the walls.

[0026] In this embodiment, a reel 61 is provided inside the shutter housing 1 to rotate through the first drive motor 6, a shutter body 2 is fixedly provided on the reel 61, and one end of the shutter body 2 extends from the bottom of the shutter housing 1. Vertical guide rails 3 are provided on both sides of the shutter housing 1 to extend downward, the vertical guide rails 3 are adapted to be provided on both sides of the shutter body 2, the bottoms of the vertical guide rails 3 are connected to the bottom plate 5, and reinforcing columns 4 are movably provided in front of the vertical guide rails 3 on both sides. By providing the reel 61 and the vertical guide rails 3, the shutter body 2 can be controlled to be raised and lowered, and by providing the reinforcing columns 4, the stability of the shutter body 2 can be enhanced. In addition, the shutter housing 1 is connected to the wall, and the vertical guide rails 3 and the bottom plate 5 are embedded in the wall, so that the shutter body 2 can be installed at the opening between the walls, the shutter housing 1 and the reinforcing columns 4 are located on one side of the wall, and the shutter body 2 is used to block the fire on the other side of the wall.

[0027] Furthermore, when the first drive motor 6 controls the reel 61 to rotate, the shutter body 2 extends downward through the vertical guide rails 3 at both ends, and finally the bottom of the shutter body 2 extends into the shutter groove 52 inside the bottom plate 5, and the shutter body 2 is fully extended. Then, the second drive motor 7 controls the bidirectional screw rod 71 to rotate, so that the screw rod pairs 8 on both sides can be located on the bidirectional screw rod 71 and move. Because the top of the reinforcing column 4 is connected to the screw rod pair 8 and the bottom is located in the transverse guide rail 51, the reinforcing column 4 can be driven by the screw rod pair 8 to move, so that the reinforcing column 4 can move from both sides of the shutter body 2 to the middle, so that the stability of the shutter body 2 can be strengthened by the reinforcing column 4 to prevent the impact of the more violent heat wave on the other side of the shutter body 2. When it is not needed, it can be retracted to the vertical guide rails 3 on both sides by the bidirectional screw rod 71 and the screw rod pair, without causing space waste.

[0028] In the present embodiment, the roller shutter body 2 can be normally retracted and extended by the arrangement of the roller shaft 61 and the vertical guide rail 3, and the screw rod pair 8 can be moved by the arrangement of the bidirectional screw rod 71, thereby driving the reinforcing column 4 to move. By moving the reinforcing column 4 from both sides of the roller shutter body 2 to its middle, the stability of the roller shutter body 2 can be enhanced, so that the roller shutter body 2 can withstand the impact caused by a larger heat wave on the other side, thereby improving its fire prevention effect.
