Description
Technical field:
The present invention relates to the door lock of elevator technical field, be specifically related to a kind of novel household ladder safety door lock device.
Background technology:
In the process of modernization, people pay attention to the raising of operating efficiency and quality of the life more, yet the contradiction of people and environment is more outstanding, and society is given in developing rapidly and the aging of structure of population, have all brought new challenge subjects for all trades and professions.The insider develops a kind of Elevator that is applicable to family expenses, villa, and this class Elevator mainly contains following advantage: low energy consumption, reduce 45% than general pressure regulation elevator energy consumption; Reduce line load, reduce current peak, low energy consumption, small capacity cable means lower installation cost and less emergency power system requirement; Reliability is high, and long service life is used highly reliable industrial semiconductor element and asynchronous motor; The high accuracy flat bed is without the direct stop of lag or lead; Low noise, motor current be near the ideal sinusoidal curve, the level and smooth and friction noise of moment.
But because the user of home lift lacks elevator professional knowledge, there is not special elevator to use the attendant, so its security performance must be protected.The complicated cost of present household ladder door latch structure is high, be not easy to installment and debugging, and its safety does not reach requirement
Summary of the invention:
The purpose of this invention is to provide the household ladder safety door lock device, it is simple in structure, and is reasonable in design, is convenient to Installation and Debugging, safe, is convenient to promote the use of.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises box body, lid, lymphogranuloma inguinale type fastener, position rotating pin, traction electromagnetism, pull bar pivot pin, limit switch base, limit switch, position-sensing switch, double contact switch, shifting lever and signal input interface, the inboard end of box body is provided with the position rotating pin, its bottom is fixed by the crossed countersunk head screw, position rotating pin outside socket lymphogranuloma inguinale type fastener, lymphogranuloma inguinale type fastener one side is provided with position-sensing switch, and matches with lymphogranuloma inguinale type fastener sidewall in the contact of position-sensing switch; The inboard other end of box body is fixed with signal input interface by the crossed pan head screw, be disposed with traction electromagnetism and double contact switch between lymphogranuloma inguinale type fastener and the signal input interface, one end of traction electromagnetism is arranged on a middle side part of lymphogranuloma inguinale type fastener, the slot of its other end and the extended spot of limit switch base plug, limit switch is fixed on the limit switch base, and matches with double contact switch in the contact of limit switch; The through hole that traction electromagnetism slot upper and lower side is passed in the lower end of pull bar pivot pin is with fixing limit switch base, and the upper end of pull bar pivot pin is fixed by the end of nut and shifting lever, and shifting lever passes the sidewall of box body and fixes by axis of rotation screw and box body; The box body upper end is provided with lid by the crossed countersunk head screw.
The present invention has following beneficial effect:
A, security reliability: traction electromagnetism energising in device, elevator is in normal operating condition, and the outer safety door of family expenses can't be opened, and play safety effect;
B, safe controllability: when this device is opened or door is in opening, be in other floor outgoing calls calling, elevator can't move this moment, guarantee personal security;
C, accurate positioning: the fish shape button of safety device is with two microswitch contactings and in disconnecting, operational stroke is small, control accurate positioning, no-failure process;
D, safety are limited: when abnormality appears in elevator device, this safety device with automatic short-circuit, close, elevator can't carry out improper running and outer elevator door also can't be opened.
