Background technique
In some malls, cell, subway, it will usually install elevator and facilitate on people downstairs, in order in elevator use process
In safety, one group of infrared light curtain transmitting and receiving device can be set on elevator door, as shown in Figure 1, working as the folding of elevator door
When having shelter on track, the reception device of infrared light curtain is triggered, and elevator door is prohibited to close, therefore is avoided that and crushes people's
It is dangerous；But infrared light curtain be usually be made of several infrared lights, therefore the gap between infrared light belong to irradiation it is blind
Area, when being located on the folding track of elevator door for some relatively fine things such as traction rope of finger, pet etc., once
Fall in the blind zone of infrared light curtain, the control system of elevator can not receive corresponding signal, and elevator door still can be according to
Stop, it is easy to bodily injury occur, pet is held in peril outside elevator, therefore existing elevator door sensitivity
It is low, risk is higher.
Summary of the invention
In order to solve above-mentioned problem of the prior art, the utility model provides a kind of pinch resistant type elevator door, solves infrared light
The problem of blind area of curtain cannot identify tiny thing, makes tiny thing that can also trigger elevator door at the blind area of infrared light curtain
Switch, guarantees the safety that elevator door uses, sensitivity with higher.
The purpose of this utility model can be realized by the following technical scheme: a kind of pinch resistant type elevator door, including symmetrically set
The left gate and right gate set, are equipped with sliding slot of the opening towards door edge in the door body of the left gate, and up and down the two of the sliding slot
End is equipped with sliding rail parallel to each other, is equipped with tablet in the sliding slot, the side up and down of the tablet is plugged on the sliding rail
It is inside slidably connected, and the tablet right edge extend out to the door of the left gate along outer；The notch of the sliding slot is equipped with limit
Position plate, the tablet are equipped with towards the seam allowance on the outside of notch, and the limit plate, which is connected on the seam allowance, makes the induction
The length that plate stretches out door edge is fixed；The door of the right gate is equipped with slot corresponding with the induction Board position, the sense at
It answers plate to stretch out in slot described in the partial insertion on the left gate door edge and is not contacted with the inner surface of the slot；The cunning
Be fixed with the pressure sensor with elevator control system signal communication on the left side bottom surface of slot, the left side of the tablet with
The elastic component of compressed state, one end of the elastic component and the pressure sensor contacts are equipped between the bottom surface of the sliding slot
Connection, the other end are fixedly connected with the tablet.
Preferably, the elastic component is " V " type elastic slice, and one end fixation of " V " the type elastic slice is connected to the tablet
On, the other end is connect with the pressure sensor contacts.
Preferably, the secondary spring of pressured state is fixedly connected between the both ends of described " V " the type elastic slice.Secondary spring makes
The both ends for obtaining " V " type elastic slice even closer can be connect with pressure sensor and tablet.
Preferably, the elastic component is compressed spring, and one end fixation of the compressed spring is connected on the tablet,
The other end is connect with the pressure sensor contacts.

When, traction rope is sandwiched between two fan doors, and for the tablet on left gate by reversed extruding force, tablet applies extruding force
To elastic component, pressure sensor detects the pressure change of elastic component, so that pressure change, which is become electric signal, feeds back to elevator
The control system of door, reopens elevator door；In addition, when hand is taken off on the elevator door in left side, pressure sensor also can and
When sense the variation of pressure difference, signal is fed back to the control system of elevator door, elevator door is opened.
Resultant effect brought by the utility model includes: the parallel cunning being plugged in slot in the side up and down of tablet
On rail, therefore when right edge any point of tablet is squeezed power, entire tablet parallel can be moved to the left, from
And inductor can receive the variation of pressure difference, and the door of elevator door is made to guarantee the safety that elevator door uses along no sense blind area
Property, sensitivity with higher；In addition, after elastic component is installed it under the action of limit plate and seam allowance cooperation are clamped
Initial pressure value in compressed state, i.e. pressure sensor is not zero, and pressure sensor is excitation with pressure difference variation
Signal controls the folding of elevator door, and while improving the sensitivity of tablet, elastic component is not only as setting initial pressure value
Zero force application part, therefore elastic component is avoided because the impaired bring inexactness of fatigue is used for a long time；Finally, tablet
The pulley of upper and lower side makes the flexible sensitiveer, conveniently of tablet, reduces the frictional force between tablet and sliding rail.
