Use reliability.
2. the hole for being used to be fixedly connected with fire prevention expansion cushion rubber on sleeve is blind hole, when preventing fire, latch multi-diameter shaft
In end insertion sleeve during fire prevention expansion cushion rubber, gone out together with fire prevention expansion cushion rubber from sleeve, further improve and use reliability.
3. latch gear fixed cover dorsad sleeve one end be provided with end cap, need to such as change fuse link, it is only necessary to pull down end
Lid, it is convenient and swift.
4. provided with fire prevention expansion cushion rubber in latch gear sleeve, when occurring fire, fuse link fusing, latch ladder shaft end is inserted
Enter in sleeve in fire prevention expansion cushion rubber, fire prevention expansion cushion rubber gradually expands, stuck fast latch ladder shaft end, it is to avoid spring force
Latch ladder shaft end is skidded off out of sleeve when not enough.
5. fire-proof expansion seal strip section be L-shaped, can simultaneously with door leaf side, counter-fire side outer layer plate contact, one
Aspect significantly improves door leaf, the sealing of doorframe junction, on the other hand, substantially reduces the strike note for generation of closing the door.
6. pick-proof steel plate is provided between the basal plate of counter-fire side, outer layer panel, on the one hand increase structural strength, the opposing party
Face can play good anti-theft function.
7. door panel is the multilayer keel shoe of fire-proof plate material, structural strength is high, can play preferable heat-insulation and heat-preservation
Effect.
