Detailed Description

As shown in the figure: the utility model relates to an elevator door stopper, which comprises a U-shaped groove 1, two stop blocks I2 and II 3, a slide block 4 arranged between the two stop blocks and used for driving the stop blocks to expand outwards, a screw 5 connected with the slide block 4, a sleeve 6 sleeved on the screw 5 and an adjusting knob 7 arranged at the top end of the screw 5; the U type inslot 1 is horizontal to be had spliced pole 8, block piece I2 and block piece II 3 cover in spliced pole 8, sleeve 6 is located between U type groove 1 and adjust knob 7, screw rod 5 pierces through 1 upper end in U type groove and 4 threaded connection of slider.

During the use, rotate adjust knob 7 will slider 4 is arranged in suitable position between two blocks to can also get into ground threshold groove after two blocks I2 and block II 3 lower extremes are opened in advance and be fit for. Then, when the elevator door is opened, the two stoppers are quickly inserted into the sill groove. Continue to rotate adjust knob 7, slider 4 can continue to shift up, blocks piece I2 and blocks piece II 3 and continue to expand outward relatively, blocks piece I2 and blocks piece II 3 and press close to with the firm in ground threshold groove two outsides until blocking piece I2, blocks piece I2 and blocks piece II 3 and no longer outwards expand this moment, and sleeve 6 is pressed at adjust knob 7 and is held down and make slider 4 lock on the screw rod 5 die for block piece I2 and block piece II 3 outside expansion state can keep, make the elevator hinder the door ware firm fixing in the ground threshold groove. Touch when elevator layer door closed operation the elevator hinder behind the door ware will stop motion. Because the two blocking blocks are rigid blocks and are locked in the sill groove, the phenomenon of looseness and falling caused by elastic deformation after the elevator is collided can not occur due to no deformation.

In the embodiment, the stop block I2 and/or the stop block II 3 are/is provided with a sliding groove 9 which is inclined inwards from top to bottom.
