[specific embodiment]
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
A kind of elevator safety door, include the telescopic door body 1 that is arranged on the elevator doorway place, door body 1 can stretch it as parallel motion on a guide rail, being provided with in a side of door body 1 can be toward the touch article 2 of 1 li contraction of door body, this touch article 2 is arranged on the body 1, can do relative motion with door body 1, be provided with the safety device 3 that a body 1 is moved to reversing sense on the door body 1, described safety device 3 includes the base plate 4 that is fixed on the body 1, on base plate 4, be hinged with rotor plate 5 and dwang 8 respectively, on rotor plate 5, be provided with inductive switch 6, on inductive switch 6, be provided with a contact 7, the upper end of described dwang 8 contacts with touch article 2, and the other end contacts with contact 7.
When the closed safe door, when people or thing are run into touch article 2, touch article 2 will be toward 1 li contraction of door body, touch article 2 shrinks inward will promote dwang 8 upper ends, and dwang 8 is rotated counterclockwise around its hinge-point, and then the lower end of dwang 8 will be rotated round about, then dwang 8 will unclamp contact 7, then inductive switch 6 will cut-off signal, and then a door body 1 will shrink inward, thereby prevents to crush people or thing.
Described safety device 3 also includes a pulling piece 9, one end of this pulling piece 9 is connected the top of rotor plate 5, the other end is connected on the body 1, and pulling piece 9 can spur the rotation of rotor plate 5 anticlockwise motions when door body 1 is closed fully makes the upper end of dwang 8 contact with contact 7; Described pulling piece 9 includes a stay cord 12 and pull bar 13, and an end of pull bar 13 is connected with stay cord 12, and the other end is connected the top of rotor plate 5.The length of described pulling piece 9 is shorter than the width of door body 1, when door body 1 is soon shut and the touch article 2 of opposite side when running into, stay cord 12 is straightened, door body 1 continues to close, it is mobile backward that stay cord 12 will drag pull bar 13 afterwards, pull bar 13 will drag rotor plate 5, rotate counterclockwise around its hinge-point, the inductive switch 6 that then is fixed on the rotor plate 5 also can and then rotate counterclockwise, and move forward contact 7, and this moment, though dwang 8 also rotates counterclockwise, both motions offset, and make dwang 8 lower ends still withstand contact 7, make a body 1 continue running, realize closing.
Be connected with push rod 10 in the bottom of rotor plate 5, be provided with a baffle plate 11 in the inboard of door body 1, push rod 10 can withstand on the baffle plate 11 when door body 1 is opened fully and spur rotor plate 5 anticlockwise motions.Also inverse time rotation of inductive switch 6 like this, contact 7 will head on dwang 8 lower ends, makes dwang 8 along its hinge-point anticlockwise motion, inductive switch 6 still keeps action, shrink inward even at this moment there is the people to promote touch article 2, contact 7, hold mode are still being pressed in dwang 8 lower ends.
Be with a retracing spring 17 on the described push rod 10, be provided with a collar 18 at push rod 10, described retracing spring 17 places between collar 18 and the side 15.When closing to the doorstep body 1, push rod 10 will leave baffle plate 11 like this, and retracing spring 17 shrinks back push rod 10 under himself elastic force effect, finishes homing action.
As shown in Figure 3, in one side of base plate 4 rollover one side 15 is arranged, be provided with two through holes 16 on side 15, described push rod 10 and pull bar 13 are by corresponding two through holes 16.Two offsides respectively are provided with a convex tendon 21 in described touch article 2 the insides, described sliding part 20 both sides correspondences respectively are provided with a guide groove 22, and guide groove 22 is stuck in 21 li of convex tendons slidably, when touch article 2 relatively moves with door body 1 like this, sliding part 20 moves on convex tendon 21, reduces friction well and walks.
