as preferred technical scheme, described slider bracket comprises upper and lower vertical bending side, described lower vertical bending side is provided with for placing strip-type hole in the middle part of half frame-type stop hook or stripe shape groove, described vertical bending side is provided with stop hook fixed orifice, after half frame-type stop hook 90 ° rotates, its top snaps in stop hook fixed orifice.
as preferred technical scheme, the cross section of described sill guide groove is d type, and described half frame-type stop hook 90 ° snaps in bottom it in d type sill guide groove after rotating.
as preferred technical scheme, the upper vertical bending side of described slider bracket is provided with mounting hole, and slider bracket is fixed on elevator door by described mounting hole and screw fit.
as preferred technical scheme, the diameter in the middle part of described half frame-type stop hook is greater than the thickness of described slider bracket.
advantage of the present invention is:
1. not only structure is simple, easy for installation in the present invention, and when elevator door is subject to hard impacts, blocks, effectively prevent elevator door from coming off bottom half frame-type stop hook and between sill guide groove, alleviates the risk that elevator passenger falls into hoistway, improves the safety factor of elevator.

wherein: 1 elevator door, 2 sill guide grooves, 3 slider brackets, the upper vertical bending side of 3-1, vertical bending side under 3-2,3-3 strip-type hole, 3-4 stop hook fixed orifice, 4 half frame-type stop hooks, 5 rubber rings, 6 mounting holes.
Detailed description of the invention
embodiment: shown in 6, a kind of anti-derail unit for elevator door, comprise elevator door slide block and sill guide groove 2, this elevator door slide block comprises and the slider bracket 3 be fixedly connected with bottom elevator door 1, and the half frame-type stop hook 4 to be arranged in parallel with slider bracket 3, be flexibly connected by rubber ring 5 bottom slider bracket 3 He in the middle part of half frame-type stop hook 4, this slider bracket 3 comprises, lower vertical bending side 3-1, 3-2, lower vertical bending side 3-2 is provided with the strip-type hole 3-3 for placing in the middle part of half frame-type stop hook 4, upper vertical bending side 3-1 is provided with stop hook fixed orifice 3-4, bottom slider bracket 3, sill guide groove 2 is put into together with rubber ring 5 in bottom half frame-type stop hook 4 and middle part, after 90 ° of rotation half frame-type stop hooks 4, the bottom of half frame-type stop hook 4 snaps in sill guide groove 2, the top of half frame-type stop hook 4 snaps in stop hook fixed orifice 3-4.
sill guide groove 2 cross section of the present invention is d type, after half frame-type stop hook 4,90 ° rotates, because d type sill guide groove 2 inner space is large, goes out young, therefore easily to make to snap in bottom half frame-type stop hook 4 in d type sill guide groove 2 and not easily to deviate from.
the upper vertical bending side 3-1 of slider bracket 3 of the present invention is provided with mounting hole 6, slider bracket 3 is fixed on elevator door 1 by mounting hole 6 and screw fit, diameter simultaneously in the middle part of half frame-type stop hook 4 is greater than the thickness of slider bracket 3, hold onto half frame-type stop hook 4 by the elastic force of rubber ring 5, prevent that first half frame-type stop hook 4 is installed and come off.
