The lower platen be arrangeding in parallel below the upper platen, buffer spring, institute are connected between the upper platen and the lower platen
State and air bag is provided with the middle part of upper platen, limited position mechanism, the position-limit mechanism bag are set at the guide rail on the upper platen
Pedestal and the be hinged fixture block being arranged on the pedestal are included, is provided between the fixture block and the upper platen and limits the fixture block
The torsion spring rotated to the guide rail side, the panel are provided with the block piece coordinated with the fixture block.
Thus, after elevator decrease speed exceedes certain limit, airbag aeration expands and promotes fixture block to rotate, and then quilt cover
Block piece on plate blocks.
As a preferred embodiment, the upper platen is provided with groove close to the rail-sides, rotating shaft is provided with the groove, it is described
Fixture block is hinged in the rotating shaft.
Thus, avoid the pivoting support of fixture block positioned at appear on the stage plate surface when fixture block expanded against to air bag interfered.
As a preferred embodiment, the block piece is the slab construction vertical with the panel.
As a preferred embodiment, the distance between the upper platen and the lower platen is more than 0.5 meter.
Thus, buffer time is extended to ensure buffering effect.
As a preferred embodiment, the quantity of the buffer spring is 4 and the projection on the car bottom surface is on described
The Central Symmetry distribution of car bottom surface.
Thus, the uniform load for the buffer spring that car is subject to is distributed in cage bottom.
As a preferred embodiment, the quantity of the fixture block is 4 and is located at two web both sides respectively.
Thus, disperse the load that single fixture block is born, reduce the destroyed risk of pedestal.
As a preferred embodiment, the car top is provided with the air bag generator being connected with the air bag.
To sum up, the utility model has advantages below：Air bag promotes fixture block rotation during expanding, and then by panel
Block piece block, final to prevent elevator from dropping, reflection is sensitive, simple and reliable for structure；Air bag expansion after coordinate upper and lower platen it
Between buffer spring coordinate to elevator fall bottom when enter row buffering, air bag fully contacts scattered under the extruding of lower platen with upper platen
Bump stroke, ensure that buffering effect.
Brief description of the drawings
Fig. 1 is a kind of structural representation of embodiment of the utility model.
Label in figure is as follows：

Groove, 42. lower platens, 43. buffer springs, 5. air bags, 6. position-limit mechanisms, 61. pedestals, 62. fixture blocks.
Embodiment
The utility model is described in further detail for middle embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes car 1, leads boots 2 and with leading leading for the clamping of boots 2 positioned at the outside of car 1
Rail 3, guide rail 3 and the quantity for leading boots 2 have two respectively.Guide rail 3 and guide rail 3 include panel 31 and the web vertical with panel 31
32, web 32 is with leading the clamping of boots 2.1 outer side-lower of car is provided with support 4, and support 4 includes the upper platen for being fixed on the bottom of car 1
41 and the lower platen 42 be arrangeding in parallel positioned at the lower section of upper platen 41, it is connected with buffering elastic between upper platen 41 and lower platen 42
Spring 43, the middle part of upper platen 41 are provided with air bag 5, limited position mechanism 6 are set at guide rail 3 on upper platen 41, position-limit mechanism 6 includes
Pedestal 61 and the be hinged fixture block 62 being arranged on pedestal 61, are provided with the limitation direction guiding rail of fixture block 62 between fixture block 62 and upper platen 41
The torsion spring that 3 sides rotate, panel 31 are provided with the block piece 33 coordinated with fixture block 62.Block piece 33 is uniform along guide rail bearing of trend
It is distributed, block piece 33 is the slab construction vertical with panel 31 in the present embodiment.After elevator decrease speed exceedes certain limit,
