When, the ratchet after the swing rod of the bidirectional ratchet mechanism drives the bidirectional ratchet mechanism to turn to inserts hook tooth to promote ratchet
Rotate in same direction, until one end of the extension bar (8) is exited in the circular hole of the door body (1) completely, the bidirectional ratchet mechanism
Stop operating, realize the self-locking of anti-explosion airtight door, and complete the opening of anti-explosion airtight door；Carried out when from the door body (1) inner side
When opening and closing anti-explosion airtight door, operating procedure is ibid.
2. a kind of pinion and-rack safety anti-explosive sealed door as claimed in claim 1, it is characterised in that door body (1) bag
Include：Fireprotection layer, external door, inside door and thermal resistance insulating barrier, the external door are supported by high strength elastic and are connected with the inside door, are had
There is good impact resistance and anti-knock properties, the resilient support is dumbbell structure, and the resilient support has multiple, uniform point
Cloth, its two ends are separately fixed on the external door and the inside door by bolt；The thermal resistance insulating barrier is filled in the external door
Between the inside door, the fireprotection layer is using the B1 fire-resistant coating for steel structures with anti-flammability and high mechanical strength, institute
Fireprotection layer is stated to be coated on the external door；The external door is made with the inside door of yield strength 35CrMo steel plates high,
The thermal resistance insulating barrier is divided into five-layer structure, is respectively internal layer, outer layer, intermediate layer and central core；The intermediate layer is two-layer, institute
It is respectively the thick Q345 steel of 10mm to state internal layer and the outer layer, and intermediate layer described in two-layer is located between the internal layer and outer layer, institute
It is 10mm thick aerogel heat-insulating felt to state intermediate layer, and the central core is located at the centre in the intermediate layer, using a heat-blocking action
The thick mineral wool panels of 60mm, the thermal resistance insulating barrier constitutes multilayer mixing planomural structure, then is aided with polyurethane foam treatment
It is filled, makes between internal layer, outer layer, intermediate layer and central core in the absence of space, realizes good thermal resistance, effect of heat insulation.
3. a kind of pinion and-rack safety anti-explosive sealed door as claimed in claim 1, it is characterised in that support frame as described above (9)
It is made of yield strength 35CrMo steel plates high, support frame as described above (9) is circular ring structure, by strengthening between annulus and annulus
Rib is connected, and is bolted on the inside door；Support frame as described above (9) is for supporting the tooth bar (7) and described stretch
Rod (8), prevents the tooth bar during rack and pinion engagement from glancing off or even has small variation, and influence is correctly nibbled
Close.
