Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As Figure 1-Figure 8, a kind of car door locking device, including a mainboard 10, door motor 7, belt 8,
Driven pulley 12 and the gantry crane plate 6 being slidably mounted in a mainboard, door motor 7 by belt 8 drive from
Driving wheel 12 rotates, and gantry crane plate 6 lower end is fixing connects gate door-plate 11, and gantry crane plate 6 is provided with main door cutter
Mechanism 5, belt 8 is connected with the linkage on main door cutter mechanism 5 by gangbar 9, main door cutter mechanism
Right blade on be fixed with secondary door cutter mechanism 4, secondary door cutter mechanism 4 includes the right cutter being fixed on main door cutter mechanism
Base plate on sheet 13 and the linkage being arranged on bottom panel side, at linkage and main door cutter mechanism 5
In the same side of base plate, base plate 13 is bolted on the right blade of main door cutter mechanism, linkage
By two connecting rods being hinged on base plate and secondary door cutter mechanism left blade 14 He that is arranged between two connecting rods
The secondary right blade of door cutter mechanism 15 is constituted, and base plate 13 another side is provided with latch hook 3, solid in door mainboard
Surely having the gear shaft 2 coordinated with latch hook, the right-hand member of latch hook 3 is provided with hook, is equipped with and is perpendicular in the middle part of latch hook 3
The dead axle 16 of base plate, dead axle 16 one end is fixing, and latch hook 3 can rotate around dead axle 16 on base 13, lock
Hook 3 rear end connects back-moving spring 18, and back-moving spring 18 other end is fixed on base plate, is not having other
In the case of external force, back-moving spring 18 is strained latch hook 3 and the hook of latch hook 3 is locked together with gear shaft 2,
Latch hook 3 upper end is fixed with triggering switch 19, door mainboard 10 is fixed with and triggers the sedan-chair that switch matches
Door lock electrical validation switch 1, latch hook 3 lower end is fixed with bearing pin 20, and base plate right side opening is provided with bore and is more than
The breach 21 of pin diameter, bearing pin 20 can move up and down left and right in breach 21, and bearing pin 20 is through breach
After be fixed with gear wheel 22, the left hand edge of the secondary right blade of door cutter mechanism 15 is provided with the flanging 17 extended to base plate,
Structure deformation on the left of flanging 17 and gear wheel, drives gear wheel 22 to move to upper right when flanging 17 moves right,
Latch hook 3 is rotated counterclockwise around dead axle 16, after secondary door cutter mechanism right blade 15 resets, is resetting
Under the effect of spring 18, latch hook 3 rotates clockwise around dead axle 16 thus is buckled on gear shaft 2.
The realization of car door lock holding function of the present utility model is divided into three kinds of situations, L.H.flapped door door cutter and R.H.flapped door
Cutter is symmetrical, and center opening door door cutter is similar with L.H.flapped door door knife structure, the most only as a example by L.H.flapped door, and R.H.flapped door
And middle enabling is in like manner.
One, elevator (non-onlocking zone) under non-flat layer state, such as elevator breaks down or elevator is normal
When the process passenger run deliberately takes off, now gate door-plate 11 moves horizontally drive gantry crane plate 6 level and moves
Dynamic, gantry crane plate 6 drives the horizontal movement of main door cutter mechanism 5, main door cutter mechanism 5 to drive secondary door cutter mechanism 4
Horizontal movement, secondary door cutter mechanism 4 band moveable lock hook 3 horizontal movement, when latch hook 3 touches gear shaft 2, lock
Hook 3 and gear shaft 2 form a mechanical lock, latch hook 3 because being blocked stop motion, gate door-plate 11 with
I.e. stopping mobile, in being so prevented from car, passenger pushs gate aside, triggers switch 19 and car door lock simultaneously
Electrical validation switch 1 disengaging, safety return circuit disconnects, and elevator can not run, and waits for rescue personnel's rescue,
Thus the passenger safety in ensureing car, now latch hook is with gear shaft location status as shown in Figure 9.
Two, elevator (onlocking zone) under flat bed state, in two kinds of situation.
1) passenger takes off door in car, and now gate door-plate 11 moves horizontally drive gantry crane plate 6 level shifting
Dynamic, gantry crane plate 6 drives the horizontal movement of main door cutter mechanism 5, main door cutter mechanism 5 to drive secondary door cutter mechanism 4
Horizontal movement, is arranged in onlocking zone hall door on bank when the right door cutter on secondary door cutter mechanism 4 touches
Secondary croquet, the secondary right blade of door cutter mechanism 15 is by level power to the right, and now secondary door cutter mechanism 4 is even
Linkage rotates clockwise, and orders about latch hook 3 and rotates counterclockwise, and then latch hook 3 departs from gear shaft 2 and opens,
Gate door-plate 11 continues to move towards taking off a direction, it is achieved passenger self-rescue in car, now latch hook and gear shaft position
Configuration state is as shown in Figure 10.
2) personnel that require assistance take off door (car is in onlocking zone) outside hall door, are now arranged on onlocking zone
In hall door, the secondary croquet on bank moves horizontally with hall door, when secondary croquet touches the secondary left blade of door cutter mechanism 14
Time, the linkage of secondary door cutter mechanism 4 rotates clockwise, and latch hook 3 rotates counterclockwise, then latch hook 3
Departing from gear shaft 2 and open, now continue to take off hall door, secondary door cutter mechanism 4 drives main door cutter mechanism 5 together
Horizontal movement, due to main door cutter mechanism 5 and gantry crane plate 6 link, gantry crane plate 6 and gate door-plate 11
Dynamic, it is achieved rescue personnel can push gate, now latch hook and gear shaft location status such as Figure 10 outside hall door aside
Shown in.
Three, during elevator normal door, door motor 7 belt wheel rotates clockwise, and drives belt 8 to rotate, skin
The linkage on main door cutter mechanism 5 is driven to rotate counterclockwise with 8 by gangbar 9, now secondary door cutter
Mechanism 4 moves upward with the right blade entirety on main door cutter mechanism 5, when forwarding certain position to, and latch hook 3
Being synchronized with the movement with secondary door cutter mechanism 4 and depart from gear shaft 2, now latch hook and door knife-like state are as shown in figure 11, main
Door cutter mechanism 5 keep this state, belt 8 be rotated further by main door cutter mechanism 5 linkage door boatswain chair 6,
Gate door-plate 11 moves together, puts in place until opening the door, thus it is unaffected to realize elevator normal door.
The passenger that this utility model is possible to prevent in car pushs car aside at the non-flat layer region of elevator, it is ensured that passenger
Can push gate aside in Elevator landing region to save oneself, rescue personnel can be outer by taking off hall door in hall door, real
Existing hall door and the linkage of gate, thus push gate aside, rescue stranded passenger.When railway carriage or compartment door is by external force, latch hook 3
Moving and make to trigger switch and the switch disengaging of car door lock electrical validation, safety return circuit disconnects, and elevator can not be transported
OK, it is ensured that passenger safety.
