A fireproof roller shutter temperature control release device includes a controller 1 and a temperature sensor 2. The controller 1 is provided with a control rod 11, the control rod 11 is provided with a functional roller 12, the controller 1 is provided with a fixing plate 3, and the temperature sensor 2 is provided with a pull rope 4. The end of the pull rope 4 away from the temperature sensor 2 passes around the functional roller 12 and is connected to the fixing plate 3.

[0031] When the temperature rises to a predetermined threshold, the temperature sensor 2 tightens the pull rope 4, thereby pulling the control lever 1 to rotate and trigger the fireproof roller shutter to close under its own weight.

[0035] Moreover, since the pull rope 4 only winds around the functional roller 12, a plurality of pull ropes 4 can be provided, and each pull rope 4 is connected with a temperature sensing piece 2, that is, the number of the temperature sensing piece 2 and the pull rope 4 is at least two, and a plurality of temperature sensing pieces 2 are arranged on both sides of the fireproof curtain, or even at different positions of the entire building, and the fireproof curtain can be closed when any one of the temperature sensing pieces 2 senses that the temperature rises to a predetermined threshold, so that the entire fireproof curtain temperature control release device can simultaneously sense the temperature of multiple positions of the fireproof curtain, the sensing range of the temperature control release control is wide, the building fire emergency is more stable, and the safety is high.

[0036] Embodiment two, still as Figs. 1 to 4 shown, is only one embodiment of the present application, and on the basis of embodiment one, the present application is a fireproof curtain temperature control release device, the fixed plate 3 is provided with a first perforation 31 and a second perforation 32 for facilitating the pull rope 4 to pass through, and the end of the pull rope 4 away from the temperature sensing piece 2 passes through the first perforation 31 and is connected with the connecting buckle 33 arranged on the second perforation 32 by winding around the functional roller 12.

[0037] The number of the first perforation 31 is the same as the number of the pull rope 4, that is, there is at most only one pull rope 4 in one first perforation 31, and the number of the second perforation 32 can be selected in many ways, the second perforation 32 can have only one or a plurality of, when the second perforation 32 has only one, all the pull ropes 4 are gathered at the second perforation and are fixedly connected by the connecting buckle 33, and when the second perforation 32 has a plurality of, there can be one or more pull ropes 4 at each second perforation 32.

[0038] In the present application, the connecting buckle 33 is arranged on the side of the second perforation 32 away from the functional roller 12, and the connecting buckle 33 is provided with a locking bolt 34.

[0039] That is, the pull rope 4 is drawn out from the temperature sensing piece 2, passes through the first perforation 31, winds around the functional roller 12, passes through the second perforation 32, is connected with the connecting buckle 33 on the side of the second perforation 32 away from the functional roller 12, and is locked with the connecting buckle 33 through the locking bolt 34 to prevent the pull rope 4 from sliding and ensure the stability of the building fire warning.

[0040] Here, the pull rope 4 outside between the temperature sensing piece 2 and the first perforation 31 is sleeved with a protective sleeve 41, that is, the pull rope 4 between the temperature sensing piece 2 and the fixed plate 3 is protected to prevent the pull rope 4 from being oxidized or damaged, and to avoid the pull rope 4 from being stuck and unable to be pulled back. The pull rope 4 can be transmitted in the protective sleeve 41, thereby facilitating the pull back.

[0041] It should be noted that the protective sleeve 41 is provided with a gasket 42 at the connection with the first perforation 31 to connect, fix and limit the protective sleeve 41.

[0043] The temperature sensing element is the main execution element of temperature rise shrinkage, the induction pull ring 22 is connected with the temperature sensing element, and once the temperature rises to a predetermined threshold, the temperature sensing element will shrink, and the induction pull ring 22 will be pulled, thereby tightening the pull rope 4. Here, the temperature sensing element can be an electric control, a temperature-sensitive memory element or a temperature-sensitive elastic element, etc.

[0044] The connecting plate 21 is arranged perpendicularly to the extending direction of the pull rope 4, the sensing pull ring 22 and the pull rope 4 are respectively located on the two sides of the connecting plate 21, the connecting rod 23 passes through the third through hole 211 on the connecting plate 21 and the two ends of the connecting rod 23 are respectively connected with the pull rope 4 and the sensing pull ring 22, the outer side of the part of the connecting rod 23 passing through the connecting plate 21 is provided with a second external thread, the adjusting nut 24 is sleeved on the connecting rod 23, the inner side of the adjusting nut 24 is provided with a second internal thread matched with the second external thread, so that the adjusting nut 24 can be threadedly connected on the connecting rod 23, and the outer diameter of the adjusting nut 24 is greater than the inner diameter of the third through hole 211, the adjusting nut 24 is located on the side of the connecting plate 21 close to the sensing pull ring 22, and the distance between the sensing pull ring 22 and the pull rope 4 can be adjusted only by adjusting the adjusting nut 24, so that the pull rope 4 can be tightened.

[0045] Generally, after the pull rope 4 is arranged, the end of the pull rope 4 away from the temperature sensing piece 2 is first locked and fixed by the locking bolt 34 and the connecting buckle 33, at this time, the pull rope 4 still has a certain relaxation, then the pull rope 4 is tightened by adjusting the adjusting nut 24, so that the sensing pull ring 22 can certainly pull the functional roller 12 when the sensing pull ring 22 is pulled.

[0046] In the utility model, the connecting plate 21 is provided with a fixed base 25, and the fixed base 25 is fixedly connected with the wall body through a plurality of base bolt holes 251.

[0047] The end of the fixed base 25 away from the connecting plate 21 is further provided with a secondary connecting plate 26, the secondary connecting plate 26 is located on the side of the connecting plate 21 away from the sensing pull ring 22, and the pull rope 4 is connected with the connecting rod 23 after passing through the pull rope hole on the secondary connecting plate 26.

[0048] Therefore, the outer side of the pull rope 4 between the secondary connecting plate 26 and the fixed plate 3 is provided with a protective sleeve 41, and the connecting part of the pull rope 4 and the secondary connecting plate 26 is also provided with a gasket 42.

[0049] In the embodiment four, still as Figs. 1 to 4 shown, only one embodiment of the utility model, on the basis of any of the above embodiments, in the utility model, the outer side of the functional roller 12 is provided with an annular limiting groove 121, and the pull rope 4 is just clamped in the annular limiting groove 121 after being tightened, so that the pull rope 4 is prevented from being pulled out of the functional roller 12.

[0050] The annular limiting groove 121 is just located at the middle part of the functional roller 12.

The control pull rod 11 actually forms a lever structure, and the control pull rod 11 rotates around the connection with the brake pad. The closer the function roller 12 is to the brake pad, the more effort is needed, but the displacement of the function roller 12 is larger under the unit displacement value of the pull rope 4. Conversely, the farther the function roller 12 is from the brake pad, the less effort is needed, but the displacement of the function roller 12 is smaller under the unit displacement value of the pull rope 4. The position of the function roller 12 can be adjusted appropriately to balance between effective lifting and lifting sensitivity of the function roller 12.

[0054] For example, if the number of temperature sensing members 2 is large and widely distributed, and the temperature control release sensitivity needs to be improved, the position of the function roller 12 is adjusted towards the brake pad. Conversely, if the length of the pull rope is large and the transmission loss is large, and effort needs to be saved, the position of the function roller 12 is adjusted away from the brake pad.

[0055] Correspondingly, a locking bolt 111 for locking the function roller 12 is arranged on the control pull rod 11. The locking bolt 111 can be arranged at the end of the control pull rod 11, at the connection with the function roller 12, or even on the function roller 12 in the area other than the annular limiting groove 121.

[0056] Here, a limiting long slot hole for limiting the rotation of the control pull rod 11 is further arranged on the controller 1 to avoid abnormal rotation of the control pull rod 11.

[0057] Finally, the control pull rod 11, the fixed plate 3 and the temperature sensing member 2 are all stainless steel or galvanized steel, and the pull rope 4 is a steel wire rope. The entire device is not prone to rust, has strong stability, long service life and high safety.
