Whether there are passenger and object to carry out infrared induction between elevator door；Infrared light curtain generally comprises infrared transmitter and infrared receiver
Device, infrared transmitter and infrared remote receiver are separately positioned on two elevator doors.But, what this infrared light curtain was produced
It is the infrared ray of lattice-shaped, there is certain blind area between its adjacent two infrared ray, (cord etc. is particularly to less object
Object) inductive effects it is undesirable, easily clamp rop for pet or clothing angle etc., sensitivity is relatively low, security is undesirable.Therefore, it is existing
With the presence of passenger lift in anti-pinch device blind area, relatively low sensitivity and the problem of undesirable security.
The content of the invention
It is an object of the present invention to provide a kind of pinch resistant type passenger lift.The present invention can not only dead zone-eliminating, raising spirit
Sensitivity, also has the advantages that security is good.
Technical scheme：A kind of pinch resistant type passenger lift, including door machine guide rail and elevator control cabinet, door machine guide rail
It is upper that two symmetrical elevator doors are connected with by hanging plate；Two relative sides of elevator door are respectively equipped with the first groove and
It is connected with two grooves, the first groove by the first spring in telescopic tongue, the second groove and is provided with piezoresistive wafer；It is described two
The infrared light curtain being vertically arranged is connected with elevator door；Fixed seat is connected with the middle part of the door machine guide rail, fixed seat side passes through
Second spring is connected with mobile infrared sensor, and mobile infrared sensor, infrared light curtain and piezoresistive wafer pass through signal wire
It is connected with elevator control cabinet.
In a kind of foregoing pinch resistant type passenger lift, the fixed seat and mobile infrared sensor are respectively positioned on two elevator doors
Between, fixed seating is in the surface of the second groove.
In a kind of foregoing pinch resistant type passenger lift, the side that infrared sensor is relatively moved in the fixed seat is provided with
The side of relative telescopic tongue is provided with the second contact-making switch, the first contact-making switch on first contact-making switch, mobile infrared sensor
It is connected with the second contact-making switch with elevator control cabinet.
In a kind of foregoing pinch resistant type passenger lift, the piezoresistive wafer is set side by side with multiple, and multiple pressure-sensitive electricity
Hinder piece parallel with one another；Gangbar is connected between two neighboring piezoresistive wafer, gangbar is located at the middle part of piezoresistive wafer.
In a kind of foregoing pinch resistant type passenger lift, between the two side of the two sides of the telescopic tongue and the first groove
It is provided with the rolling post of more than 2.
Compared with prior art, present invention improves over passenger lift structure, by setting telescopic tongue and piezoresistive wafer pair
The less object such as cord is detected that cord is pressed to and produces pressure to piezoresistive wafer after piezoresistive wafer by telescopic tongue, is led
The resistance variations of piezoresistive wafer are caused, then whether elevator control cabinet changes opening elevator door or closure elevator door according to resistance；
By setting mobile infrared sensor, second spring and fixed seat, start mobile infrared sensor when elevator is soon closed,
The infrared detection of movable type is carried out on vertical direction, coordinates infrared light curtain to use, blind area present on infrared light curtain can be eliminated；
So as to realize 3 re-detections of anti-pinch, sensitivity and security are improved.In addition, the present invention is provided with the first contact-making switch and the
Two contact-making switches, mobile infrared sensing can be opened by the second contact-making switch when elevator door promotes mobile infrared sensor
Device, mobile infrared sensing can be closed by the first contact-making switch when mobile infrared sensor is moved to contact fixed seat position
Device simultaneously terminates to move the anti-pinch detection of infrared sensor, can lower energy consumption while Detection results are ensured；It is many by setting
Piece piezoresistive wafer parallel with one another and gangbar can be detected by more pieces of pressure sensitive resistor disc simultaneously, not only increase spirit
Sensitivity, additionally it is possible to prevent monolithic piezoresistive wafer from failing and cause anti-pinch detection failure, further improve security.Therefore, originally
Invention can not only dead zone-eliminating, improve sensitivity, also have the advantages that energy consumption is low and security is good.
