Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the door lock of elevator that the utility model provides, comprise selvage 1, lock crook plate 3, conductive contact 11 and conductive contact 12, selvage 1 and lock crook plate 3 place respectively on the left and right door of elevator door, and the position is corresponding, lock crook plate 3 is provided with latch hook 7, the lockhole 8 on the selvage 1, and latch hook 7 is complementary with lockhole 8; Conductive contact 11 and conductive contact 12 place respectively on the left and right door of elevator door, and conductive contact 11 and conductive contact 12 are complementary.Lock crook plate 3 is fixed on the latch hook base plate 4 by bearing pin 6, is provided with spring 14 between lock crook plate 3 and the latch hook base plate 4; Spring 14 1 ends are connected on the lock crook plate 3, and the other end is connected on the latch hook base plate 4, and spring 14 can make the rotation of lock crook plate 3 recover.At this, spring 14 can be extension spring, also can adopt torsion spring.
Lock crook plate 3 is provided with
conductive contact 12, selvage 1 is fixed on the door interlock
switch base plate 5, door interlock
switch base plate 5 is provided with
lock box 10, be provided with the
conductive contact 11 that is used with
conductive contact 12 in the
lock box 10, when door lock of elevator was closed, contact 11 contacted with conducting
block 12, elevator conducting operation, when door lock of elevator was opened, contact 11 disconnected with conducting
block 12, and elevator disconnects and not moving.Lock
crook plate 3 is fixed by latch hook base plate 4 and a fan elevator door wherein, and selvage 1 is fixed by door interlock
switch base plate 5 and another fan elevator door.It is characterized in that being provided with the
block 9 of unblanking on
lock crook plate 3,
block 9 places of unblanking are provided with the connecting
rod 2 of unblanking.The described connecting rod of unblanking can be "
" font, the connecting rod of unblanking "
" the font bending place is provided with bearing.Unblank connecting
rod 2 around bearing 13 rotations, on
lock crook plate 3, be provided with unlocking rod 15.In order to guarantee that
latch hook 7 effectively inserts in the lockhole 8 of selvage 1 at closing time, selvage 1 is provided with guiding
slope 16, and when
latch hook 7 was in the highest position of guiding
slope 16,
conductive contact 11 and
conductive contact 12 were in contact position.When door lock of elevator breaks down, can promote to
unblank block 9 by the connecting
rod 2 of unblanking, thereby the
latch hook 7 that drives on the
lock crook plate 3 breaks away from lockhole 8, opens elevator door; Also can break away from lockhole 8 by the
latch hook 7 that unlocking
rod 15 drives on the
lock crook plate 3.
