The light frequency of 15b differs.So it is to ensure to receive the light of different optical transmitting sets by optical receiver to judge a left side
The state of terraced door 1a, right terraced door 1b, for example whether there is folder passenger-in-elevator.
The left first optical receiver 9a only receives the left first optical transmitting set 13a, a left side the 4th optical transmitting set 15a
Light, the right first optical receiver 9b only receive the right first optical transmitting set 13b, the light of the 4th optical transmitting set 15b of the right side, institute
The light that the second optical receiver 17a of a left side only receives the left second optical transmitting set 12a is stated, the right second optical receiver 17b is only
The right second optical transmitting set 12b, the light of the 3rd optical transmitting set 14b of the right side can be received, the 3rd optical receiver 16 only receives
The light of the 3rd optical transmitting set 14a of a left side.Corresponding optical receiver receives the light of corresponding optical transmitting set, can go to judge left terraced door 1a, the right side
The state of terraced door 1b, for example whether there is folder people.
Preferably, the quantity of the left spring 5a is five, the bottom of the vertical left groove 3a of the left spring 5a
Face and the left side for moving to left motion block 4a, one end of five left spring 5a, which is separately fixed at, described moves to left motion block 4a left ends
On the central point in face and four endpoints；The quantity of the right spring 5b is five, the vertical right groove 3b of the right spring 5b
Bottom face and the right side for moving to right motion block 4b, one end of five right spring 5b, which is separately fixed at, described moves to right motion block 4b
On the central point of right side and four endpoints.So left spring 5a, right spring 5b can make to move left block 4a, move to right motion block 4b more
It is steady mobile.
Preferably, the most significant end for moving to left motion block 4a, the most significant end for moving to right motion block 4b, lowermost end and lift port 19,
Lowermost end matches.So in the altitude range of lift port 19, motion block 4a is moved to left, motion block 4b is moved to right and may be used to anti-pinch,
Without height dead angle.
Preferably, left chain wheel 6a, left projection are installed respectively on the lower face for moving to left motion block 4a and moving to right motion block 4b
7a and right pulley 6b, right projection 7b, the left projection 7a are located at the right side of the left chain wheel 6a and are sent out positioned at left first light
The left side of emitter 13a, the right projection 7b are located at the left side of the right pulley 6b and positioned at the right first optical transmitting set 13b's
Right side；The left groove 3a, right groove 3b lower face on a left stopper 8a, right stopper 8b, the left resistance are installed respectively
Block 8a is located at the right side of the left projection 7a and on the track of the mobile route of the left projection 7a, the right stopper
8b is located at the left side of institute right projection 7b and on the track of the mobile route of the right projection 7b.Left chain wheel 6a, right pulley 6b
It can make to move to left motion block 4a, move to right motion block 4b reduction mobile frictional forces.Left projection 7a, left stopper 8a and right projection 7b, right stop
Block 8b cooperate can be adjusted together with left spring 5a, right spring 5b move to left motion block 4a, move to right motion block 4b stretch out left groove 3a,
The distance of right groove 3b.
The operation principle of this anti-pinch elevator door is as follows：After left terraced door 1a, right terraced door 1b are opened, left first optical receiver
9a, the first optical receiver 9b of the right side are located at outside left groove 3a, right groove 3b respectively, the first optical transmitting set 13a of a left side, right first light emitting
