20, fusible link 21 is connected between connection sheet 20 and baffle 17.
In the present embodiment, the head end of positive stop strip 15 is engaged with 14 activity of ratchet-gear wheel, and baffle 17 passes through second with fore-set 19
18 elastic force of compressed spring connects, and the left side of Scroll 5 is fixedly connected with ratchet-gear wheel 14 by triggering rack 13 certainly, of the invention
Running can be voluntarily triggered in fire from triggering rack 13, roller shutter door body 1 is fallen in time and closes, and the effective barrier intensity of a fire is climing
Prolong, positive stop strip 15 engages under the thrust of the first compressed spring 16 with ratchet-gear wheel 14, limits the position of ratchet-gear wheel 14, the second compression
It is retracted state when spring 18 is flat, when fire, fusible link 21 is fused by high temperature or fire, the rebound of the second compressed spring 18, rebound
Active force pushes fore-set 19 and makes fore-set 19 that positive stop strip 15 be pushed to rotate, and then the top of positive stop strip 15 is made to divide with ratchet-gear wheel 14
From, and then under the gravity of clump weight 2, drive ratchet-gear wheel 14 to be rotated simultaneously with Scroll 5, and then will be under roller shutter door body 1
Drop has effectively obstructed the sprawling of the intensity of a fire until closing, and is Mechanical Driven from the component in triggering rack 13, can effectively prevent
Circuit is only damaged when fire causes failure in service.
Certainly, in the specific implementation, the bottom surface of clump weight 2 and rubber buffer 3 and roller shutter door body 1 is fixed successively connects
It connects, and the rubber buffer 3 that rubber buffer 3 is rubber material, clump weight 2 can accelerate roller shutter door body 1 to decline in fire
Speed, to make intensity of a fire iris action in time, rubber buffer 3 can effectively be buffered the power that roller shutter door body 1 declines, and be prevented
Only 1 decrease speed of roller shutter door body is too fast causes to damage or deform.
In the present embodiment, fireprotection layer 101 be equipped with two layers, and two layers of fireprotection layer 101 respectively with the front and back table of roller shutter door body 1
Face fits closely, and the surface area of fireprotection layer 101 is equal with the surface area of roller shutter door body 1, and fireprotection layer 101 has good barrier fire
Gesture and the performance for preventing baked wheaten cake, roller shutter door body 1 is damaged by fire when can prevent fire from occurring, and improves safety and practicability.
A kind of operation principle and implementation from triggering fire resistance rolling shutter door of the present invention is as follows：
First, by mounting base 6 and two side position of top for being mounted on sliding groove 4 respectively from triggering rack 13, immediately
It and electric rotating machine 8 is connected into external power supply by conducting wire, controlling electric rotating machine 8 by control button 12 rotates, and then makes actively
Gear 9 drives driven gear 11 to rotate by driving chain 10, and then makes Scroll 5 under the drive of driven gear 11 by roller shutter
Door body 1 is wound, and positive stop strip 15 engages under the thrust of the first compressed spring 16 with ratchet-gear wheel 14 at this time, limits the position of ratchet-gear wheel 14
It sets, and the second compressed spring 18 is retracted state, when there is fire generation, fusible link 21 is fused by high temperature or fire, the second compression
Spring 18 is sprung back, and the active force of rebound pushes fore-set 19 and makes fore-set 19 that positive stop strip 15 be pushed to rotate, and then makes positive stop strip 15
Top is detached with ratchet-gear wheel 14, and then under the gravity of clump weight 2, and ratchet-gear wheel 14 is driven to be rotated simultaneously with Scroll 5, into
And roller shutter door body 1 is declined until closing, has effectively obstructed the sprawling of the intensity of a fire, clump weight 2 can accelerate rolling screen door in fire
The speed that body 1 declines, to make intensity of a fire iris action in time, rubber buffer 3 can have the power that roller shutter door body 1 declines
Effect buffering prevents 1 decrease speed of roller shutter door body is too fast from causing to damage or deform, and after fire fighting, is replaced by manual operation complete
New fusible link 21 resets the second compressed spring 18 and fore-set 19, and above is exactly the entire operation principle of the present invention.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
