[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 , Figure 2 As shown, a fire-resistant partition structure for commercial facilities within a public building includes: columns 1 on both sides of the commercial facility, with a horizontal bar 11 between the two columns 1; a fire-resistant roller shutter 2 rotatably connected to the columns 1, the fire-resistant roller shutter 2 including a pivot 21 and a curtain body 22, the curtain body 22 being wound around the pivot 21; an equipment platform 3 slidably connected to the columns 1, with a fire extinguishing device 31 mounted on the equipment platform 3; a protective cover 4 located at the top of the horizontal bar 11, with a nozzle 41 at the front end of the protective cover 4; a limiting mechanism 5 located at the front end of the horizontal bar 11, the limiting mechanism 5 contacting the bottom of the curtain body 22; and a linkage mechanism 6 located between the pivot 21 and the equipment platform 3.

[0025] The column 1 has a limiting channel 12 on its side, which is vertical. The bottom of the curtain 22 has a counterweight 221, and the upper part of the curtain 22 is fireproof cloth. The counterweight 221 drives the curtain 22 to unfold downward from the pivot 21. The two ends of the counterweight 221 are slidably connected to the limiting channel 12. The limiting channel 12 restricts the curtain 22 to be in a vertical state when it is unfolded and after it is unfolded, ensuring the area of ​​fire separation, and at the same time preventing the curtain 22 from shaking and causing the fire to spread.

[0026] The front end of the column 1 is provided with a first slide rail 13, which is located on the adjacent side of the column 1 and is also vertical. The rear end of the equipment platform 3 is provided with a slider 32, which is slidably connected to the first slide rail 13. When no fire occurs, the equipment platform 3 is located above the first slide rail 13, and the fire extinguishing equipment 31 is stored in the roof of the building, thus saving commercial building space. When a fire occurs, the equipment platform 3 moves downward, causing the fire extinguishing equipment 31 to fall down, making it easier for firefighters to replenish fire extinguishing supplies. The fire extinguishing equipment 31 mainly consists of various types of fire extinguishers and fire buckets.

[0027] The front end of the first slide 13 is equipped with several deceleration bars 14, with adjacent deceleration bars 14 spaced at the same distance. The deceleration bars 14 are made of flexible material, and their rear ends are fixed to the column 1. When the equipment platform 3 falls, it decelerates by colliding with the deceleration bars 14, preventing the equipment platform 3 from falling too fast and damaging the fire extinguishing equipment 31, and also preventing the equipment platform 3 from causing injury to people in the partitioned space.

[0028] The bottom of the equipment platform 3 is equipped with support legs 33 and an alarm 34. When the equipment platform 3 falls, the alarm 34 sounds an alarm to remind people below to take shelter. After the equipment platform 3 lands, the support legs 33 support the ground.

[0029] When the curtain 22 is rolled up onto the shaft 21, the limiting mechanism 5 is used to restrict the start of the curtain 22, such as... Figure 3 As shown, the limiting mechanism 5 includes a rotating rod 51, a lifting rod 52, a telescopic rod 53, a blade 54, and a force-bearing rod 55. One end of the rotating rod 51 is rotatably connected to the crossbar 11, and the other end of the rotating rod 51 supports the counterweight 221. When the rotating rod 51 rotates downward, the counterweight 221 is released from the restriction, causing the curtain 22 to move downward. The force-bearing rod 55 is located above the rotating rod 51, and its rear end is fixedly connected to the crossbar 11. The lifting rod 52 connects the rotating rod 51 and the force-bearing rod 55. When the lifting rod 52 is fully extended, the rotating rod 51 cannot rotate downward. The telescopic rod 53 is located behind the lifting rod 52, and the blade 54 is located at the telescopic end of the telescopic rod 53. The blade 54 moves back and forth with the telescopic end of the telescopic rod 53.

[0030] The lifting rod 52 is made of hot-melt material. The top of the lifting rod 52 passes through the support rod 55, and the bottom of the lifting rod 52 passes through the rotating rod 51. The top and bottom areas of the lifting rod 52 are larger than the middle area. A force-receiving groove 551 is provided below the support rod 55, and the blade 54 faces the force-receiving groove 551. In the event of a fire, the telescopic rod 53 can be manually activated. The telescopic rod 53 drives the blade 54 to move. The blade 54 pushes the middle of the support rod 55 to the force-receiving groove 551, and finally cuts the support rod 55 under the push of the blade 54. After the support rod 55 breaks, the rotating rod 51 rotates downward under the action of gravity, disengaging from the counterweight 221, thereby lowering the curtain 22 to complete the fireproof separation. If the fire is concealed and the temperature is too high, the lifting rod 52 will melt and break, at which point the curtain 22 will automatically lower.

[0031] When the curtain 22 is lowered, the linkage mechanism 6 drives the equipment platform 3 to move downward as well. For example... Figure 4 As shown, the linkage mechanism 6 includes a gear shaft 61, a rack 62, a limiting rod 63, and a second slide rail 64. The gear shaft 61 is located on the side of the rotating shaft 21. When the curtain 22 is lowered and unfolded, the rotating shaft 21 rotates, thereby driving the gear shaft 61 to rotate as well. The rack 62 meshes with the gear shaft 61 and is fixedly connected to the limiting rod 63. The second slide rail 64 is fixedly connected to the column 1. The front end of the second slide rail 64 is open. The top end of the limiting rod 63 is slidably connected to the second slide rail 64. The top of the equipment platform 3 is provided with a third slide rail 35, and the bottom end of the limiting rod 63 is slidably connected to the third slide rail 35. The second slide rail 64 restricts the downward movement of the limiting rod 63, thereby restricting the equipment platform 3 to the top of the first slide rail 13. When the gear shaft 61 rotates, it drives the rack 62 to move forward, thereby driving the limiting rod 63 to move forward. When the limiting rod 63 disengages from the second slide rail 64, the equipment platform 3 is no longer restricted and moves downward under the action of gravity.

[0032] The protective cover 4 is wide enough to cover the fireproof roller shutter 2 and the equipment platform 3, thus maintaining the aesthetics of the public building. The sprinkler head 41 is connected to a fire hose, and in the event of a fire, the sprinkler head 41 participates in the fire-fighting linkage to spray water to assist in extinguishing the fire.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
