Description
Technical Field
[0001] The utility model relates to the technical field of fire rolling shutter doors, in particular to a folding fire smoke proof rolling shutter door. Background Art
[0002] Fire shutter doors, also known as fireproof shutter doors, are fire-proof and heat-insulating facilities suitable for larger openings in buildings. Under the control of the fire central control system, the fireproof shutter doors will automatically be lowered according to a preset program, thereby preventing the flames from spreading to other areas and buying precious time for firefighting.
[0003] When the existing foldable fire rolling shutter door is lowered, the airflow generated by the flame can easily push the curtain to shake, and there is usually no connecting structure at the junction of the bottom of the curtain and the ground of the building opening, so that there is a gap between the curtain and the ground, so that the smoke generated in the fire can easily pass through the gap and emerge into another space, resulting in a poor smoke-proof effect of the rolling shutter door; in addition, when the bottom of the existing fire rolling shutter door encounters long-term accumulation of debris, it is easily disturbed by the debris and cannot be closed normally, which will interfere with the normal lowering of the curtain surface on the rolling shutter door and even affect the fire-proof effect of the rolling shutter door.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figures 1 to 4As shown, the foldable fire-fighting smoke-proof rolling shutter door of this embodiment includes a chassis 1, which is used to store the rolled-up curtain surface 2 and is usually hidden in the ceiling of the building. A controller connected to the fire central control system is also installed inside the chassis 1 to ensure that the motor 8 can be driven in time. The motor 8 is fixedly installed inside the chassis 1, and a reel 9 is engaged with the output end of the motor 8. The curtain surface 2 is movably connected to the outside of the reel 9. The curtain surface 2 is made of inorganic fireproof cloth material and has high fire resistance. A slide plate 4 is engaged with the bottom end of the curtain surface 2. The width of the slide plate 4 is the same as that of the bottom plate 6, so that the slide plate 4 can fit more closely with the bottom plate 6. A slot 1 is provided at the bottom end of the slide plate 4. 6, the function of the card slot 16 is to enable the movable strip 5 protruding from the bottom plate 6 to be smoothly embedded in the slide plate 4, so as to strengthen the connection relationship between the bottom plate 6 and the slide plate 4, thereby reducing the probability of a gap between the bottom plate 6 and the slide plate 4 after being fitted together. The bottom end of the chassis 1 is fixedly connected with a door frame 3, and the function of the door frame 3 is to pull the curtain surface 2 down smoothly, so that the curtain surface 2 maintains better stability when it is unfolded through the reel 9, and reduces the probability of the curtain surface 2 shaking when it is unfolded, thereby facilitating the contact and fitting of the slide plate 4 and the bottom plate 6. The bottom end of the door frame 3 is fixedly connected with a base 7, and the base 7 is installed below the ground of the opening, so that the ground where the rolling shutter door is installed will not have a high threshold-like protrusion, reducing the road To prevent the interference caused by pedestrians passing through the hole, a bottom plate 6 is provided on the top of the base 7. The top of the bottom plate 6 is flush with the ground, so that the structure below the bottom plate 6 can be buried underground, which is more conducive to protecting the base 7. A movable bar 5 is provided in the middle of the bottom plate 6. The top of the movable bar 5 is "semi-circular arc-shaped", the surface is relatively smooth, and it is not easy to adhere to debris, and the top of the movable bar 5 protrudes from the top of the bottom plate 6, but it will not cause interference to pedestrians. A spring 14 is provided at the bottom of the movable bar 5. The function of the spring 14 is to enable the movable bar 5 to be smoothly reset when it is not pressed down. A button switch 10 is fixedly installed in the middle of the inner side of the bottom plate 6. The button switch 10 is a long-press button switch 10, which needs to be pressed. It takes more than ten seconds to connect the circuit, thereby reducing the risk of the button switch 10 being accidentally touched. A cavity 13 is provided inside the base 7. The cavity 13 can make the sound emitted by the buzzer 12 resonate in the cavity 13, amplify the sound of the buzzer 12, and make it easier for people to hear. The buzzer 12 is fixedly installed in the middle of the cavity 13, and electric push rods 11 are fixedly installed on both sides of the cavity 13. After the power is turned on, the electric push rods 11 can push the bottom plate 6 upward, so that the objects pressed on the movable bar 5 and the bottom plate 6 are lifted and slide to one side of the bottom plate 6, thereby avoiding the objects staying directly below the curtain surface 2 for a long time, reducing the interference caused by the normal lowering of the curtain surface 2.
[0024] Specifically, a guide rail is fixedly installed inside the door frame 3, and the curtain surface 2 is movably connected to the door frame 3 via the guide rail. The guide rail can enable the curtain surface 2 to maintain better stability when unfolding and lowering, thereby facilitating the contact and fit between the slide plate 4 at the bottom end of the curtain surface 2 and the bottom plate 6.
[0025] Furthermore, the slide plate 4 is movably connected to the bottom plate 6 through the curtain surface 2, and the movable bar 5 is movably connected to the card slot 16 through the bottom plate 6. After the slide plate 4 and the bottom plate 6 are in contact and fit, the movable bar 5 will be embedded in the card slot 16, so that the gap between the slide plate 4 and the bottom plate 6 after the contact is further reduced. At the same time, magnetic blocks are embedded in the bottom plate 6 and the slide plate 4, so that the bottom plate 6 and the slide plate 4 can be adsorbed and tightly attached by magnetic force when in contact.
[0026] Furthermore, the button switch 10 is located directly below the active bar 5, and the button switch 10 is electrically connected to the buzzer 12 and the electric push rod 11 respectively. The button switch 10 is connected in series with the buzzer 12 and the electric push rod 11, so that when the button switch 10 is turned on, the buzzer 12 and the electric push rod 11 will be energized at the same time.
[0027] Furthermore, the output end of the electric push rod 11 is snap-connected with the bottom end of the bottom plate 6, and the bottom plate 6 is movably connected with the base 7 through the electric push rod 11. The bottom plate 6 can be pushed up to a position above the ground by the electric push rod 11, so that objects stacked on the bottom plate 6 and the movable bar 5 can be pushed open, thereby preventing the objects from staying directly below the curtain surface 2 for a long time.
[0028] Furthermore, a groove 15 is provided inside the bottom plate 6, and the bottom end of the spring 14 is fixedly connected to the bottom inside the groove 15. The groove 15 is used to press down the movable bar 5, so that the movable bar 5 can trigger the button switch 10 in the groove 15 after being pressed down.
[0029] Furthermore, the top end of the spring 14 is fixedly connected to the bottom end of the movable bar 5, and the movable bar 5 is movably connected to the bottom plate 6 through the spring 14. When the movable bar 5 is not subjected to downward pressure from an object, the spring 14 will push the movable bar 5 to reset, so that the movable bar 5 is separated from the button switch 10.
[0030] The method of using the present embodiment is as follows: when using the present foldable fire smoke shutter door, the present shutter door can be first installed at a larger opening of a building. At this time, the base 7 needs to be installed in a pre-buried groove. After the installation is completed, the top surface of the bottom plate 6 should be flush with the ground of the opening, and only the top of the movable bar 5 protrudes from the ground. Then the shutter door is connected to the fire central control system and the external power supply is turned on. When a fire occurs, the motor 8 will drive the reel 9 to unfold the curtain surface 2 from the chassis 1, so that the curtain surface 2 is lowered along the guide rail in the door frame 3. At this time, the slide 4 at the bottom end of the curtain surface 2 will move toward the top of the bottom plate 6. When the bottom surface of the slide 4 contacts the top surface of the bottom plate 6, the movable bar 5 will be engaged with the card slot 16, and at the same time, the bottom plate 6 and the slide The plate 4 will be tightly adsorbed by the magnetic force generated by the built-in magnetic suction block, so that smoke is not easy to come out of the curtain surface 2 and the ground of the hole, and when an object is placed on the top of the movable bar 5 for a long time, the movable bar 5 will be pressed by the pressure of the object and move into the groove 15, so that the spring 14 in the groove 15 is compressed, and at the same time the movable bar 5 will press the button switch 10 for a long time, so that the button switch 10 is triggered, so that the buzzer 12 and the electric push rod 11 are energized at the same time, and the buzzer 12 will make a sound at this time to give a voice reminder to the people around, and at the same time the electric push rod 11 will push the bottom plate 6 to rise, so that the objects pressed on the movable bar 5 and the bottom plate 6 are pushed away, so that the objects are pushed to one side of the bottom plate 6, so that there is no object stacked directly under the curtain surface 2.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
