Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting facilities, in particular to a fireproof rolling curtain which is convenient for escape. Background Art

[0002] Fireproof roller shutters are fire-fighting facilities installed at the exits, passages, corridors and other locations of a building to cut off the path of fire spread and buy time for people to evacuate and extinguish fires. They are usually made of high-temperature resistant materials and can resist the erosion of flames and heat.

[0003] In order to ensure that the fireproof rolling shutter does not affect the evacuation of personnel, an escape structure is usually provided on the fireproof rolling shutter, which includes an escape door that can be opened and closed on the surface of the fireproof rolling shutter, or an emergency switch that controls the fireproof rolling shutter to be retracted to a corresponding height so that personnel can pass smoothly;

[0004] However, when facing a fire scene, for people to evacuate through the escape door, the opening steps of the escape door are complicated and cumbersome, and the evacuees need to have relevant experience to successfully open the door and escape. After passing through, the door needs to be closed to ensure the fireproof effect of the fireproof roller shutter. The previous and subsequent steps take a lot of time, wasting the escape time at the fire scene;

[0005] For personnel evacuating through the emergency switch, after pressing the switch, the drive structure needs to reel in the fireproof roller shutter so that the lower end of the fireproof roller shutter rises to a level where personnel can pass through and escape. The reeling process of the fireproof roller shutter also takes a long time, usually about 30 seconds, so the escape time from the fire scene is extremely wasted in the reeling process.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0027] Combination Figure 1-Figure 5A fireproof roller shutter for facilitating escape comprises a roller shutter body 3, the roller shutter body 3 is mounted at a passage opening of a wall 1, a reeling portion 2 for reeling in the roller shutter body 3 is fixedly mounted on the upper side of the passage opening of the wall 1, inner walls on both sides of the passage opening of the wall 1 are provided with guide rail mechanisms 4 for guiding the movement of the roller shutter body 3, the guide rail mechanisms 4 comprise a first guide rail 41 and a second guide rail 42 arranged in an upper and lower manner, an escape mechanism 5 is connected between the first guide rail 41 and the second guide rail 42, and the escape mechanism 5 is fixedly mounted inside the wall 1.

[0028] The utility model is further described below in conjunction with embodiments.

[0029] The first guide rail 41 is fixedly installed on the inner wall of the passage opening of the wall 1, and the second guide rail 42 is movably installed on the inner wall of the passage opening of the wall 1;

[0030] The escape mechanism 5 includes a rotating ring 55 fixedly arranged on the upper side of the second guide rail 42, and a docking ring 54 fixedly arranged on the lower side of the first guide rail 41. The rotating ring 55 and the docking ring 54 are coaxially arranged in a horizontal plane. A driving column 53 is arranged on the axis of the docking ring 54. The driving column 53 is transmission-connected to the rotating ring 55. One end of the driving column 53 is connected to a driving structure. A control switch for triggering the driving structure is provided on the surface of the wall 1.

[0031] The above technical scheme and technical effects are as follows: the rotating ring 55 and the docking ring 54 are connected in series through the activity of the driving column 53, so that the second guide rail 42 is directly below the first guide rail 41, and the second guide rail 42 swings on the lower side of the first guide rail 41. The rolling shutter body 3 in the winding part 2 falls from the first guide rail 41 and the second guide rail 42, and after isolating the passage opening of the wall 1, when people need to evacuate through the passage opening, the driving structure can be started by controlling the switch to drive the driving column 53 to rotate, prompting the driving column 53 to drive the rotating ring 55, and then drive the second guide rail 42 to quickly tilt to the side away from the people, so as to support the rolling shutter body 3 in the groove of the second guide rail 42 to be parallel, thereby opening the passage so that people can quickly evacuate through the passage opening.

[0032] In the previous embodiment: the driving structure includes a servo motor 51 fixedly installed inside the wall 1, and a gearbox 52 is provided at the output end of the servo motor 51. The output end of the gearbox 52 is coaxially fixedly connected to the driving column 53, and the gearbox 52 automatically changes speed to adjust the coordination between the output kinetic energy of the servo motor 51 and the rotational torque of the docking ring 54, thereby accelerating the time for the gearbox 52 to be propped up.

[0033] In the previous embodiment, the length of the second guide rail 42 is adapted to the height range required by the personnel escape passage, so that the second guide rail 42 supports the height of the roller shutter body 3 to facilitate smooth passage of personnel, reduce the difficulty of passing, and save passing time.

[0034] In the previous embodiment: the surface of the roller shutter body 3 is provided with a plurality of hinges 31 for folding and rolling up the roller shutter body 3, and the hinge 31 of the driving column 53 is coaxially arranged, so that when the second guide rail 42 drives the roller shutter body 3 to bend, the bent portion of the roller shutter body 3 is located at the position where the hinge 31 is located, thereby avoiding damage to the roller shutter body 3 during bending.

[0035] In the previous embodiment: at least one movable groove A58 is formed on the annular inner wall of the rotating ring 55, and a slide groove 44 is formed on the inner wall of the slide rail of the second guide rail 42. The upper side of the slide groove 44 is connected to the inner side of the rotating ring 55, and the lower side is connected to the lower surface of the second guide rail 42. A movable groove B59 is also formed at the connection point between the inner wall of the rotating ring 55 and the slide groove 44.

[0036] One end of the driving column 53 is movably engaged with the inner side of the rotating ring 55. A plurality of push blocks 56 are fixedly connected to the arc surface of the driving column 53, and an arc-shaped top block 57 is fixedly connected to the lower surface thereof. The plurality of push blocks 56 correspond to the plurality of movable grooves A58 one by one. The push blocks 56 move inside the movable grooves A58 along the direction of rotation of the driving column 53, and the arc-shaped top block 57 moves inside the movable grooves B59.

[0037] A latch 43 is slidably arranged in the slide groove 44, the upper surface of the latch 43 is arranged as a convex arc surface, a cylinder is arranged in the middle, and the lower surface is flush with the lower surface of the second guide rail 42, and a push spring 45 and a fixing ring 46 are movably sleeved on the surface of the cylinder, the fixing ring 46 is arranged on the lower side of the push spring 45, and is fixedly connected to the inner wall of the slide groove 44, and the upper end of the push spring 45 is fixedly connected to the surface of the cylinder;

[0038] A socket for plugging with the plug 43 is provided on the ground below the plug 43 .

[0039] The above-mentioned technical scheme and technical effects are as follows: the arc-shaped top block 57 on the lower side of the driving column 53 pushes the lower end of the pin 43 to the lower surface of the second guide rail 42, and inserts it into the socket on the ground, thereby limiting the rotation of the second guide rail 42, so as to avoid the pressure difference on both sides of the roller shutter body 3 caused by a fire. The resulting pressure causes the roller shutter body 3 of the second guide rail 42 to swing and lift up, affecting the fire-proof effect of the roller shutter body 3. When the driving column 53 rotates in the rotating ring 55, the movement of the push block 56 in the movable groove A58 will cause the arc-shaped top block 57 to be misaligned with the pin 43. At this time, the push spring 45 will lift the pin 43 and disconnect it from the ground socket. Then the push block 56 will push the rotating ring 55 to rotate, thereby driving the second guide rail 42 to be propped up to one side.
