The specific embodiment
A kind of fire protection door as Figure 1-4, comprise door-plate 1, door handle 3, door lock 5 and opal 4, door-plate 1 is provided with forms 2, forms 2 are between opal 4 and door handle 3, and the base of forms 2 and door-plate 1 are hinged, and forms 2 comprise luffer boards 25 and window frame 24, on luffer boards 25, be provided with window handle 21 and sash lock 22, window handle 21 is connected with sash lock 22 in luffer boards 25 inside, is connected with folding support frame 23, the flame resistant glass layer that described forms are airtight setting between luffer boards 25 and window frame 24.This design can be in the situation that not opening gate, can be compared with the observation outdoor situations of wide-angle, as the situation of big fire and smog, stopping entering of big fire and smog, ensure indoor people's safety, or delay the admission velocity of big fire and smog, for next step behavior of saving oneself of indoor people gains time.
A simultaneously airtight forms that is arranged on of flame resistant glass layer, and luffer boards 25 itself when upper (and be fitted in) form dual iris action, thereby the intrusion of effectively stopping big fire and smog has guaranteed to demonstrate,prove the fireproof performance of fire protection door.
As shown in Figure 3, the section of window frame 24 is stairstepping, and an outdoor side of close door-plate 1 is the first ladder, near door core one side, is the second ladder.This structure can guarantee smooth in an outdoor side of fire protection door, and can directly not expose the gap of forms 2, arrives good sealing effectiveness, thereby has good security performance.
As shown in Figure 3, the section of luffer boards 25 is stairstepping, and an indoor side of close door-plate 1 is the first ladder, near door core one side, is the second ladder.Can engage with door-plate 1, and folding support frame 23 is hidden in the gap of door-plate 1 and forms 2, not affect the outward appearance of fire protection door.
As shown in Figure 3, when folding support frame 23 is stretched to maximum rating, luffer boards 25 and door-plate 1 are in plumbness.In use, folding support frame 23 has played the effect of supporting luffer boards, makes 1 one-tenth, luffer boards 2 and door-plate vertical, forms a platform, facilitates the placement of kinds of goods, and when signing a bill or pay dues, can serve as the effect of desktop.
The width of folding support frame 23 is less than the thickness of described door-plate 1.Be conducive to folding support frame 23 to be hidden in door-plate, do not affect the outward appearance of fire protection door.
What window handle 21 can rotate up and down is connected with sash lock 22.When pulling window handle 21 downwards, can open sash lock 22, when window handle is decontroled, its automatic rebounding is to origin-location, and the dead bolt of sash lock 22 is ejected into original position simultaneously.
As shown in Figure 1, on described luffer boards 25, be provided with latch 7.Can guarantee the security performance of forms, thereby improve the security performance of fire protection door.
As shown in Fig. 1 or 2, door handle 3 is fixed on door-plate 1, and door handle 3 belows are provided with knob 6, and knob 6 is connected with door-plate 1 inside with door lock 5.Door handle 3 can not start door lock 5, has prevented that outdoor people from using instrument to open fire protection door by forms 2, and the knob 6 of its below is for opening or lock the device of door lock 5.
