The specific embodiment
Below in conjunction with Figure of description and embodiment, the utility model is further described.
The locking drive mechanism of this Subway Tunnel protective airtight partition door, be connected with the doorframe 1 and the hermatic door 2 that are placed in subway tunnel, the inner side edge of doorframe 1 is provided with some latch receptacles 11, the edge of hermatic door slides and is provided with the lock pin corresponding with latch receptacles 21, the locking drive mechanism 3 of this Subway Tunnel protective airtight partition door comprises worm screw case 31, guide rod 32 and connecting rod assembly 33, guide rod top is divided and is provided with screw thread, worm gear screw thread in this guide rod through threaded and worm screw case is in transmission connection, and connecting rod assembly connects guide rod and lock pin 21; When worm screw in worm screw case is rotated, guide rod inserts or leaves latch receptacles by connecting rod assembly band pendulum lock pin.
Guide rod 32 is longitudinally arranged on hermatic door movably, connecting rod assembly 33 comprises some horizon bars 331 and some changements 4, horizon bar 331 can be arranged on guide rod both sides and one end transverse shifting and be connected with horizon bar 331 by changement 4, and the other end is connected with the lock pin 21 that is positioned at the longitudinal both sides of hermatic door.If arrange at this point, be provided with how many lock pins in the both sides of hermatic door and just need how many horizon bars 331, under the situation of many horizon bars, the motion of each rod member easily interferes, make whole connecting rod assembly stuck, and the increase of rod member makes whole mechanism more heavy, must increase the load capacity of hermatic door.For this reason, increased the setting of lock pin bar.
Horizon bar 331 is set to four and be symmetrically distributed in the both sides of guide rod, horizon bar is connected with lock pin 21 by two lock pin bars 333, two lock pin bars are longitudinally arranged on respectively the both sides of hermatic door, this lock pin bar is connected with horizon bar respective end, some lock pins that hermatic door both sides longitudinally distribute are all connected with lock pin bar, when horizon bar transverse shifting, thus lock pin bar thereupon transverse shifting insert or leave corresponding latch receptacles 11 with pendulum lock pin.
In considering horizontal locking, in order to solve the problem of longitudinal locking, connecting rod assembly also comprises longitudinal rod 332, longitudinal rod is arranged on hermatic door with longitudinal movement, its one end is connected with horizon bar by changement, its other end is connected with the lock pin that is positioned at hermatic door top edge, drives corresponding lock pin to insert or leave latch receptacles thereby drive longitudinal rod to vertically move by changement when horizon bar transverse shifting.
Above-mentioned latch actuation mode, has mainly considered the horizontal blocking function of hermatic door.
Certainly, if what hermatic door was mainly taked is longitudinal closedown mode, guide rod 32 can move horizontally and be arranged on hermatic door, now connecting rod assembly 33 comprises some the second longitudinal rods 34 and changement 4, the second longitudinal rod 34 is distributed in the both sides up and down of guide rod with longitudinal movement, second longitudinal rod one end is connected with guide rod 32 by changement, its other end is connected with the lock pin that is positioned at the upper and lower dual-side of hermatic door, when worm gear in worm screw case rotates, thereby guide rod moves horizontally and drives the second longitudinal rod to vertically move to drive corresponding lock pin to insert or leave corresponding latch receptacles.
Above-mentioned changement 4 comprises inverting seat 41, arc ripping bar 42 and connecting rod 43, inverting seat is fixedly installed on large door leaf, arc ripping bar middle part is arranged in inverting seat rotationally, one end of arc ripping bar and connecting rod one end are hinged, and the other end of arc ripping bar and the other end of connecting rod connect with two mutually perpendicular corresponding rod members of the direction of motion respectively.In the time of guide rod lengthwise movement, thereby the horizon bar connecting with guide rod by changement moves horizontally with the lock pin on pendulum lock pin bar and lock pin bar and inserts or leave corresponding latch receptacles, and the longitudinal rod being connected by changement with horizon bar vertically moves; If when guide rod moves horizontally, the second longitudinal rod connecting by changement with guide rod vertically moves the corresponding lock pin of same drive and inserts or leave blocking seat.
There is not deviation in the transmission direction in order to ensure guide rod, hermatic door is fixedly installed guide holder 5, in guide holder 5, be provided with the axis of guide (not shown in FIG.), guide rod is provided with gathering sill 321 along its length in middle part, and guide rod 32 is slidably arranged in guide holder and the axis of guide is positioned at gathering sill.
In use, rotate the manual pulley 311 being connected with the worm screw in worm screw case, there is corresponding rotation in worm gear, thereby ordering about guide rod moves along its length, then drive corresponding little lock to insert or leave corresponding latch receptacles by corresponding connecting rod assembly, realize locking or unlatching to hermatic door.
The utility model makes subway sealed partition door under outage condition, can rely on manually locking in time comparatively effortlessly by labour-saving worm screw case comparatively and the connecting rod assembly that is attached thereto.
