Embodiment
The technical solution of the utility model is elaborated below in conjunction with the accompanying drawings.
A kind of airtight blast door, including door leaf body 100, door leaf body 100 have two, and the door leaf body 100 is be hinged
In on wall, folding is realized by way of docking.The bottom of door leaf body 100 is provided with door opening 101, is provided with door opening 101
Small door leaf 102.Small door leaf 102 is arranged on door leaf body 100 by hinge page, and small door leaf 102 is to outwardly open.When door leaf body
100 when being closed, and a small amount of personnel can be entered out by small door leaf 102.
It is provided with cavity 110 referring to Fig. 2, in small door leaf 102, the left and right side of cavity 110 is provided with opening 111, in cavity 110
Be rotatably connected to lock core 120, when small door leaf 102 be in can open mode when, lock core 120 is placed in cavity 110；When small door leaf
102 when being in locking states, rotates lock core 120 and causes opening of the lock core 120 from the left and right side of the small internal cavity 110 of door leaf 102
111 stretch out, and door leaf body 100 is provided with the lockhole for two ends for being used to accommodate lock core 120, passes through the both ends of lock core 120
Cooperation with lockhole realizes the locking to small door leaf 102.
It is not that small door leaf is arranged on by connectors such as screws because lock core 120 is provided in the inside of small door leaf 102
102 surface, it compensate for because the bonding strength of screw is weaker so that the shortcomings that small door leaf 102 is easily broken through.
Specifically, lock core 120 is to be rotatably connected on steel column in cavity 110, steel column by transmission mechanism come drive its
Rotated in cavity 110 with locking or open small door leaf 102.Transmission mechanism includes, and is fixedly connected on lock core 120 and door leaf body
First gear 200 at 100 rotation connections, first gear 200 are engaged with the first worm screw 201, on the body of rod of the first worm screw 201
The second gear 202 coaxially connected with worm screw is fixed with, second gear 202 is engaged with the second worm screw 203, the first described tooth again
The 200, first worm screw 201 of wheel, second gear 202 are arranged inside small door leaf 102, and the body of rod of the second worm screw 203 passes perpendicularly through
The interior shop front of small door leaf 102, the second worm screw 203 have handwheel 204 in the small external stability of door leaf 102.Above-mentioned structure is due to adding
Worm screw and the structure of gear engagement, have a self-lock ability, i.e. gear is unable to reverse drive worm screw and rotated so that small door leaf 102
Locking states it is relatively reliable.
In order to improve the intensity of lock core 120, lock core 120 can be arranged to several steel columns being set parallel to each other, steel column
Between connected by connecting pole 121.
This airtight blast door also provides a kind of auto-open-lock device, and described auto-open-lock device includes being arranged on small door leaf
