Description
Technical field
The present invention relates to the technical field of lift facility, especially a kind of elevator door lock assembly.
Background technology
Elevator is power with electrical motor, and box like gondola is housed, and takes advantage of people or carrying goods for tier building, and vertical lift elevator has a car, operates between the vertical rigid guideway of at least two row.Mid-term in 19th century starts to occur hydraulic elevator, still applies on low-rise building so far.1852, the E.G. Otis of the U.S. developed the safety cage of rope hoisting.The eighties, actuating device has further improvement, as electrical motor is driven winding reel by worm drive, adopted counterbalanced weight etc.In 19 end of the centurys, have employed frictional wheel drive, greatly increase the hoisting depth of elevator.20 the end of the centurys elevator adopt permanent magnetic synchronous traction machine as power, greatly reduce machine room and take up an area, and have the advantages such as energy consumption is low, efficient energy-saving, hoisting speed are fast, greatly boosting real estate is to Super High future development.
Door lock of elevator is the important component part of elevator, but existing most of door lock of elevator exists some defects on structure design, and these defects will cause the complex structure of door lock of elevator, and safeguard loaded down with trivial details, structural soundness is poor, and door lock working stability is poor.
Summary of the invention
The technical problem to be solved in the present invention is: in order to solve the prior art Problems existing in above-mentioned background technology, provide a kind of elevator door lock assembly, reasonable in design, structural soundness and strong operability.
The technical solution adopted for the present invention to solve the technical problems is: a kind of elevator door lock assembly, comprise two symmetrical door lock mechanisms, described each door lock mechanism has door lock permanent seat, the door lock being positioned at the door lock auxiliary hook base below door lock permanent seat and being positioned between the two, described door lock comprises the crotch shape primary door latch that afterbody is fixedly mounted on door lock permanent seat front end, the middle position of described crotch shape primary door latch is provided with the door latch spring perpendicular with it, the head side of crotch shape primary door latch is provided with the crotch shape door lock auxiliary hook be fixedly mounted on door lock auxiliary hook base, described crotch shape door lock auxiliary hook and crotch shape primary door latch are combined to form N shape structure, the head of crotch shape primary door latch is also provided with door lock drive wheel, described each door lock mechanism also has contact switch, and described contact switch comprises the floatless switch part being fixedly mounted on crotch shape primary door latch head and the movable switch part be movably arranged on door lock auxiliary hook base.
Further specifically, be fixedly connected with by lock shaft between door lock permanent seat and crotch shape primary door latch.
Further specifically, be fixedly connected with by hex screw between crotch shape door lock auxiliary hook and door lock auxiliary hook base.
Further specifically, door lock permanent seat, door lock auxiliary hook base and door lock are provided with zinc coating.
The invention has the beneficial effects as follows: elevator door lock assembly of the present invention has the following advantages:
One, the middle position of door lock between door lock permanent seat and door lock auxiliary hook base, is in outside door lock permanent seat and the door lock of door lock auxiliary hook base to middle part plays a very good protection, and avoids the damage of external environment to door lock;
Two, crotch shape door lock auxiliary hook and crotch shape primary door latch are combined to form N shape structure, form good symmetrical application force, ensure that steadiness between the two between crotch shape door lock auxiliary hook and crotch shape primary door latch;
Three, contact switch adopts split-type design, under ensureing the fixed situation of a wherein part, allows another one part be in active state, increases the alerting ability of contact switch and movable regionality.
