Surely there is the floor 323 of reinforcing, when activity threshold 31, which is stowed in, to be accommodated in storehouse 32, it is to live that support frame 321, which substitutes traction mechanism,
Dynamic threshold 31 provides support, bears the pressure generated from surface car personnel to activity threshold 31 in daily passage, reduces
Traction mechanism stress protects traction mechanism；Support base 322 is then rotatablely connected with drive rod 36, is supported drive rod 36, is avoided being driven
Bar 36 deforms in rotation and influences transmission effect.
As shown in Figure 1, surface of wall is equipped with protective door 41, protective door 41 and the rotation connection of maintenance 4 side of storehouse.Usually beat
Protective door 41 is opened so as to operating repairs, close protective door 41 then can to avoid maloperation and to the component in maintenance storehouse 4 into
Row protection.
The present embodiment in use, 31 upper surface of activity threshold is concordant with ground, facilitates traffic to pass through usually；When need
When sealing, operator need to only rotate handwheel 331, and the rotation of handwheel 331 is converted into turning for drive rod 34 by retarder 33
It is dynamic, it commutates further through transmission case 35 be converted to the rotation of drive rod 36 later, the effect of the rotation of drive rod 36 in commutator 39
Under be converted into the rotation of screw rod 38, be converted to vertically moving for sleeve 37 with being threadedly coupled for screw rod 38 eventually by sleeve 37,
Then it drives activity threshold 31 to move up and down, realizes the lifting of activity threshold 31.Since 31 surface of activity threshold is covered with sealing
Item, therefore after closing door leaf 2, activity threshold 31 is just realized with 2 following table face contact of door leaf compression to door leaf 2 and ground upwards
Sealing between face eliminates the trouble of separately installed movable sill, improves the speed in a closed circuit of airtight blast door.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
