Middle setting spring and movable block, one end of the movable block contacted with spring, the other end of the movable block is fixedly connected with card
Block, the side of the threshold open up card hole, and the fixture block sticks into the card hole of threshold, and one end of the link block connects rocking bar.
Preferably, the threshold opens up the back side setting sealant of card hole, and the sealant is Nian Jie with threshold.
Preferably, the card hole on the threshold is cone shaped countersink, and one end for sticking into card hole of the fixture block is round table-like.
Preferably, the fixed cylinder is fixedly connected or is welded by screw with placing groove.
Preferably, the rocking bar is L-shaped bar, and one end of rocking bar is connected by hinge and movable block rotation, the rocking bar
Bending part by shaft and placing groove rotation connect.
The beneficial effects of the utility model are: placing groove is arranged on the threshold of this movable placed type threshold airtight blast door, limit
Slot is used for the positioning of threshold, and when installation is more convenient, while gripping mechanism being arranged on placing groove, the card in the gripping mechanism
Block can push down threshold, and threshold is pressed in, and the gap of threshold and door-plate lower end helps to seal, the compression of fixture block and pine
Rocking bar adjusting was opened, can save strength, the installation of threshold and was removed conveniently.
The threshold of this movable placed type threshold airtight blast door is clamped device and is pressed on door-plate and door-plate, helps to seal, card
The compression of block and unclamping is adjusted by rocking bar, the installation of threshold and removes convenience.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of movable placed type threshold airtight blast door, including doorframe 1, door-plate 2 and threshold 4, doorframe 1, door-plate 2
Placing groove 3 is arranged in the two sides of rotation connection, the doorframe 1, and the both ends of the threshold 4 are stuck in placing groove 3, and limiting groove 3 is used for
The positioning of threshold 4 during installation, convenient for the installation of threshold 4.
Further, the gripping mechanism of the side setting clamping threshold 4 of the placing groove 3, the gripping mechanism includes solid
Determine cylinder 5, spring 6, movable block 7, rocking bar 8 and fixture block 9, the fixed cylinder 5 is fixedly connected with the outer wall of placing groove 3, fixed circle
Cylinder 5 is fixedly connected or is welded by screw with placing groove 3, the middle setting spring 6 and movable block 7 of fixed cylinder 5, the activity
One end of block 7 is contacted with spring 6, and the other end of the movable block 7 is fixedly connected with fixture block 9, opens up through-hole on 3 wall of placing groove, card
Block 9 is passed through from the through-hole of placing groove 3, and the side of the threshold 4 opens up card hole, and the fixture block 9 sticks into the card hole of threshold 4,
