Description
Technical field
The utility model relates to a kind of station platform safety door lock, specifically, is a kind of emergent door lock of station platform safety door.
Background technology
Station platform safety door emergent door lock is mounted in the front shelves of escape door doorframe tubing.General station platform safety door emergent door lock is all 2, world locking, meets the certain rigidity requirement of door body under blast.The mode of operation of emergent door lock is push rod release, and when occurring that the emergent stream of people squeezes in a large number, release also can directly push like this.And existing door lock is how separated with door body, be as parts independently, comparatively complicated and dead bolt and the ground scratching after opening the door of its structure, makes deficiency in application life.
Summary of the invention
Goal of the invention: the purpose of this utility model be to provide a kind of simple in structure, dead bolt not with ground scratching, service-strong emergent door lock.
Technical scheme
The utility model adopts following technological means to realize:
The safe emergent door lock of a kind of skeleton symbol platform, comprise door leaf, door leaf sets gradually upper connecting rod away from a side of hinge from top to bottom, middle lock body, lower link, upper connecting rod, lower link connects respectively the dead bolt of the latch lock that is arranged on the upper and lower two ends of door leaf, middle lock body is arranged on door leaf away from the middle part of a side of hinge, middle lock body comprises cam, arm-tie, middle plate, cam is overlapped on arm-tie Shang Qieyu lock core shaft coaxial rigid and connects, a side of plate in the middle of arm-tie connects by bearing pin, middle plate is fixed on door leaf by rotating shaft, both sides in middle plate connect upper connecting rod and lower link with bearing pin respectively.
Middle part in door leaf and a hinged side arranges ratchet and pawl arrangement, described ratchet and pawl arrangement comprises ratchet and ratchet, one end of ratchet contacts with ratchet, the other end stretches out door leaf external surface, in the rotating shaft of ratchet, torsion spring is set, middle part at door leaf arranges push rod, and one end and the ratchet of push rod are rigidly connected, and the other end and rotating shaft are rigidly connected.
Beneficial effect: compared with prior art, it is arranged on lockset on door leaf the utility model, and it is simple in structure, is easy to safeguard, and after opening the door, utilizes click to block dead bolt, dead bolt not can with ground scratching, greatly extend application life.

The specific embodiment
Below in conjunction with manual, the utility model is described in further detail:
The utility model relates to the safe emergent door lock of a kind of skeleton symbol platform, comprise door leaf, door leaf sets gradually upper connecting rod 2 away from a side of hinge from top to bottom, middle lock body 3, lower link 4, upper connecting rod 2, lower link 4 connects respectively the dead bolt of the latch lock 1 that is arranged on the upper and lower two ends of door leaf, middle lock body 3 is arranged on door leaf away from the middle part of a side of hinge, middle lock body comprises cam 7, arm-tie 8, middle plate 9, cam 7 is overlapped on arm-tie 8 Shang Qieyu lock core shaft coaxial rigid and connects, a side of plate 9 in the middle of arm-tie 8 connects by bearing pin, middle plate 9 is fixed on door leaf by rotating shaft 11, both sides in middle plate 9 connect upper connecting rod 2 and lower link 4 with bearing pin respectively.
Middle part in door leaf and a hinged side arranges ratchet and pawl arrangement 6, described ratchet and pawl arrangement 6 comprises ratchet 12 and ratchet 11, one end of ratchet 11 contacts with ratchet 12, the other end stretches out door leaf external surface, in the rotating shaft of ratchet 11, torsion spring is set, at the middle part of door leaf, push rod 5 is set, one end of push rod 5 and ratchet 12 are rigidly connected, and the other end and rotating shaft 10 are rigidly connected.That is to say, ratchet 12, push rod 5, middle plate 9 are rotated together with rotating shaft 10 all the time, and when ratchet 11 rotates, ratchet 12 is all the time at ratchet 11 surface slidings, and stops ratchet 11 to run back.
Below by object lesson, the utility model is described:
During door leaf locking, ratchet 12 stretches out one end stopping due to doorframe of door leaf surface, concordant with door leaf surface, the other end of ratchet 12 is separated with ratchet 11, when passenger meets emergency in door, along the direction of opening the door, promotes push rod 5, in the middle of push rod 5 directly drives, plate 9 is rotated, thereby pulled upper connecting rod 2, lower link 4, upper and lower pull bar drives respectively the dead bolt of corresponding latch lock 1 separated with stopper, realizes the unlocking function of door lock; The ratchet 12 that push rod 5 other ends connect is simultaneously followed push rod and is rotated together, after door is opened, under the drive of torsion spring, ratchet 11 stretches out the outstanding door leaf surface in one end of door leaf, and the other end and ratchet 12 Surface Contacts, along with the rotation of ratchet 12, ratchet 11 slips over a tooth of ratchet 12 and again meshes with next tooth, thereby control ratchet 12, cannot reverse, therefore can keep the released state of push rod, and then keep the contraction state of dead bolt;
As attendant outdoors, during with the key operated lock core in four directions, lock core shaft's rotating cam 7, the rotation of cam 7 is stirred arm-tie 8 and is moved upward, and then one end of middle plate 9 is up drawn, the lower link 4 being simultaneously connected with one end with middle plate 9 is also upwards drawn, and makes door leaf lower springs lock 1 dead bolt and moves down and be separated from lower backset; When drawing, under the rotation of the lock tongue in midline plate 9 that upper connecting rod 2 is controlled, also by pull-up downwards the upper backset of disengaging, realize the function of upper and lower dead bolt release simultaneously on lower link 4; Middle plate 9 is rotated and is driven push rod 5 to rotate, and the rotation of push rod 5 drives the interlock of ratchet and pawl arrangement 6, keeps the contraction state of dead bolt.
At closing time, directly promote escape door rotation, the dead bolt of two latch locks 1 up and down of door leaf enters after backset, and ratchet 11 stretches out one end of door leaf surface and can collide with doorframe, ratchet 11 reversions, and ratchet 11 is separated with ratchet 12, thereby removes the control to ratchet 12 reversions; Dead bolt enters after stopper, and under the effect of the spring arranging on dead bolt, dead bolt resets, and completes locking.
