The specific embodiment
Describe concrete technology contents of the present utility model and embodiment in detail below in conjunction with accompanying drawing.
Structural representation when accompanying drawing 1 and accompanying drawing 2 are represented locking state of the present utility model and released state respectively, comprise the sliding seat assembly that has now in the gate lock technology by above-mentioned accompanying drawing structure of the present utility model as can be seen, billiards, unblank to hit bow, lock bottom plate, guide peg etc., the gate lock that is installed on the gate head plate moves up and down in hoistway with car, be installed with secondary lock hook assembly 12 on the door machine link plate, in the switch door, move horizontally with door machine link plate, unblank to hit bow 8 and be installed on the every head plate of the Room, the length of hitting bow is within the onlocking zone scope that allows.Two guide pegs 11 up and down are installed on the main lock bottom plate 20, sliding seat assembly 6 is installed on guide peg 11, one side of guide peg 11 is equipped with compression spring 14, and sliding seat assembly 6 is provided with can be around the main hook assembly 2 of axle 5 rotations, and main hook assembly 2 is provided with a billiards 4.
Go up the structural representation of contact assembly in accompanying drawing 3 expression the utility model.
The structural representation of contact assembly under in accompanying drawing 4 expression the utility model.
With reference to accompanying drawing 3,4, be fixed with contact support 18 with bolt 10 above the main latch hook 15, contact 1 is fixedly installed on the contact support 18 on the electric switch.Be fixed with contact support 19 down with bolt 17 on secondary latch hook base plate, contact 13 is fixedly installed in down on the contact support 19 under the electric switch.Wherein contact 1 is connected with the control system of elevator on the electric switch, and its contact 13 under electric switch carries out demonstration validation to the locked position of latch hook, to guarantee the locking fully of latch hook.
At closing time, motor drags a machine link plate motion, the secondary lock hook assembly 12 that is fixed as one with door machine link plate also moves when end thereupon, screw on the secondary lock hook assembly 12 is ramed and 3 is contacted and promote its motion with sliding seat assembly 6, at this moment, billiards 4 deviate from open hit the bow 8, active force therebetween fades away, main hook assembly 2 is rotated counterclockwise closure around axle 5 under the effect of spring 21 and deadweight, electric switch is also closed, when secondary lock hook assembly 12 further acts on, compression spring 14 is continued compression, billiards 4 with hit bow 8 and produce certain clearance.Otherwise, in the process of opening the door, being fixed in screw on the auxiliary hook lock set 12 rams and 3 removes the active force that acts on the sliding seat assembly 12 gradually, sliding seat assembly 12 is under the accumulation of energy power effect of compression spring 14, drive main hook assemblies 2 horizontal motion along guide peg 11, be installed in billiards 4 on the main hook assembly 2 and strike at end of travel and unblank to hit bow 8, under its reaction force, billiards 4 drives main hook assemblies 2 around axle 5 unhooks that turn clockwise, the release of realization gate locking device; In addition, when car hinders when resting against in the onlocking zone for some reason, the passenger can open gate by manually taking off, gate drives secondary lock hook assembly 12 horizontal movement together on its fixing door machine link plate, screw on the secondary lock hook assembly 12 is ramed and 3 is reduced gradually with the active force of sliding seat assembly 6, at this moment, the accumulation of energy power on the compression spring 14 changes active thrust into and drives sliding seat assembly 6 to the direction motion of opening the door, thereby realizes passive release in the sedan-chair.
The utility model is equally applicable to single fan/single open-door, or fan the door lock clamping system of side opening door/many folding doors, center opening more, these structures and embodiment of the present utility model are basic identical, and the main distinction is installation site, geometry and size different of secondary lock hook assembly 12.
