The specific embodiment

Describe concrete structure of the present utility model in detail according to Fig. 1-Fig. 4.This device comprises the left boatswain chair 13 that is assembled in elevator door, right boatswain chair 14 and seat board 12, lock body 3 reaches the switch bracket with its fastening, be provided with on the guide rail 15 of seat board 12 by steel rope bonded assembly left side boatswain chair 13 and right boatswain chair 14, lock body 3 is fastened on latch hook support 10 on the right boatswain chair 14 by axle 11, lock body 3 is gone back the latch hook wheel support 7 of two secondary latch hook wheels 8 of captive joint band, this lock body hook 19 with lock and square opening 20, switch bracket comprises the left-handed opening support 1 that is fixed on hook with lock on the left boatswain chair 13 and is fixed on the right switch bracket 6 of band square opening on the seat board 12, the square opening of the latch hook of lock body 3 and right switch bracket 6 fastens, the latch hook of the square opening of lock body 3 and left-handed opening support 1 fastens, and also is provided with the quiet door contact support 2 and the hook 16 of unblanking on seat board 12.

By gravity fastens in order to make between lock body and the switch bracket all the time, (this device does not embody in the drawings then also to be provided with weight-driven on the lock body, the purpose of its setting is to replenish the power that lock body pivots, and can not fasten or fasten not tight because the gravity of lock body is not enough with switch bracket to prevent).

In order to prevent lock body 3 and to rotate excessively with the latch hook wheel support 7 of two secondary latch hooks wheels 8, reduce the noise that clashes into simultaneously, fixedly install glue head caging bolt 9 on the right boatswain chair 14 of latch hook support 10 both sides.

Moving door switch contact pilotage is set on left-handed opening support 1 and the lock body 3, quiet door switch contact is set on quiet door contact support 2 and the right switch bracket 6, the door switch contact pilotage 17 of left-handed opening support is corresponding with the quiet door switch contact 18 of quiet door contact support 2, and the moving door switch contact pilotage 4 of lock body 3 is corresponding with the quiet door switch contact 5 of right switch bracket 6.

When elevator runs to the district, door cutter on the door machine device on the elevator cage passes between two secondary latch hook wheels 8, when the door machine opens the door, the door cutter opens, clash into two secondary latch hook wheels 8, drive latch hook wheel support 7, lock body 3 is together around axle 11 clickwises, this moments two, secondary latch hook wheel 8 was determined the angle of its rotation by the adjustment of latch hook wheel support 7 lower surfaces and glue head caging bolt 9, lock body 3 is thrown off with the square opening that is fixed on the right switch bracket 6 on the seat board 12 by rotating its latch hook 19, the square opening 20 of lock body 3 is thrown off with the latch hook on the left-handed opening support 1, a this moment door machine opens the door and drives right boatswain chair 14 and move right along the guide rail on the seat board 12 15, left side boatswain chair assembly 13 is moved to the left by bonded assembly steel rope between the two and realizes opening the door action, moving door switch contact pilotage 17 on the left-handed opening support be fixed on seat board 12 on quiet door contact support 2 on quiet door switch contact 18 throw off mutually, and 5 disengagements of the quiet door switch contact on moving door switch contact pilotage on the lock body 34 and the right switch bracket 6, detect by whole apparatus for controlling elevator control.When the elevator door-closing in-place, door cutter on the door machine device shrinks, this moment lock body 3 around axle 11 left-hand revolutions, its latch hook 19 is just fallen in the square opening of right switch bracket 6 under the effect of gravity, and the square opening 20 of lock body 3 is just fallen the purpose that reaches locking on the latch hook of left-handed opening support 1.When lock body 3 rotations, adopt the spacing noise that reduced of glue head caging bolt 9, driven lock body 3 by the key hole on the door pocket by the hook 16 of unblanking on the door gear of the Room during outward swinging door and clockwise rotate, realized outer unblanking.
