The technical solution of the utility model is: a kind of lockset of dual fail-safe comprises outrigger, pulley and support are installed on outrigger, on support, run through ratchet and wheel carrier are installed, on ratchet and wheel carrier, be equipped with spring, spring has the elasticity trend that ratchet and wheel carrier are moved down; The top of support is provided with adjustable shelf, fixedly shank and lock pin on described adjustable shelf, be connected with drag-line on adjustable shelf, guy cable rounds pulley is connected with operation handwheel, the upper end of ratchet and the lower end of shank are provided with suitable grab, and the upper end of wheel carrier is wedge shape corresponding with the transverse axis in push pedal; The below of support is provided with ratchet bar, and the bottom surface of ratchet bar is provided with lock hole, and the lower end of ratchet can be meshed with ratchet bar, and lock pin can penetrate in lock hole.
On described outrigger, be fixed with spacing catch.
On described outrigger, be fixed with upper stroke switch and lower stroke switch, upper stroke switch is corresponding with adjustable shelf, and lower stroke switch is corresponding with ratchet bar lower surface.
The lower end of described ratchet bar is provided with running roller.
The utlity model has following beneficial effect: owing to taking technique scheme, adopted the structure of ratchet and lock pin double locking, for visitor's safety provides guarantee, easy to use, safe and reliable.

1-outrigger in figure, 2-pulley, 3-support, 4-ratchet, 5-wheel carrier, 6-spring, 7-adjustable shelf, 8-shank, 9-lock pin, 10-drag-line, 11-grab, 12-push pedal, 13-ratchet bar, 14-lock hole, the spacing catch of 15-, 16-upper stroke switch, 17-lower stroke switch, 18-running roller.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By Fig. 1 in conjunction with shown in Fig. 2, Fig. 3, Fig. 4, a kind of lockset of dual fail-safe comprises outrigger 1, and pulley 2 and support 3 are installed on outrigger 1, runs through ratchet 4 and wheel carrier 5 are installed on support 3, on ratchet 4 and wheel carrier 5, be equipped with spring 6, spring 6 has the elasticity trend that ratchet 4 and wheel carrier 5 are moved down; The top of support 3 is provided with adjustable shelf 7, fixedly shank 8 and lock pin 9 on described adjustable shelf 7, on adjustable shelf 7, be connected with drag-line 10, drag-line 10 is walked around pulley 2 and is connected with operation handwheel, the lower end of the upper end of ratchet 4 and shank 8 is provided with suitable grab 11, and the upper end of wheel carrier 5 is wedge shape corresponding with the transverse axis in push pedal 12; The below of support 3 is provided with ratchet bar 13, and the bottom surface of ratchet bar 13 is provided with lock hole 14, and the lower end of ratchet 4 can be meshed with ratchet bar 13, and lock pin 9 can penetrate in lock hole 14.Owing to taking technique scheme, during use, outrigger 1 is fixed on passenger cabin, ratchet bar 13 is connected to presses on thick stick, visitor fastens pressure thick stick after entering passenger cabin, ratchet bar 13 penetrates in lockset from the below of ratchet 4 and wheel carrier 5, the wheel of wheel carrier 5 lower ends moves up under the progradation of ratchet bar 13, the upper end of wheel carrier 5 drives push pedal 12 to be moved to the left, push pedal 12 by the head of ratchet 4 toward left translation, ratchet 4 and the grab 11 of shank 8 are departed from, ratchet 4 moves down and is meshed with ratchet bar 13 under the effect of spring 6, now ratchet bar 13 is locked by ratchet 4, can only unidirectional propelling can not retreat, formed first insurance, when ratchet bar 13 enters certain distance, then rotating operation handwheel, drag-line 10 loosens, and adjustable shelf 7 moves down, and lock pin 9 is inserted in lock hole 14, has formed like this second insurance, meanwhile, shank 8 also moves down and blocks mutually with ratchet 4, and lockset now pins completely.While opening lockset, rotating operation handwheel, mentions adjustable shelf 7 by drag-line 10, disposable ratchet 4 and lock pin 9 are pulled up completely, pull out ratchet bar 13, in ratchet bar 13 moving process, because wheel carrier 5 does not move down, push pedal 12 is not moved, and ratchet is blocked in now push pedal 12, when ratchet bar 13 skids off completely, wheel carrier 5 is to moving down, and push pedal 12 also and then moves right, and ratchet 4 is raised to peak, lockset is opened completely, and all parts is returned to original position.The utility model has adopted the structure of ratchet 4 and lock pin 9 double lockings, for visitor's safety provides guarantee, easy to use, safe and reliable.
On described outrigger 1, be fixed with spacing catch 15.Spacing catch 15 limits the extreme higher position that adjustable shelf 7 is raised, and avoids the lower end of ratchet 4 to be retracted in support 3.
On described outrigger 1, be fixed with upper stroke switch 16 and lower stroke switch 17, upper stroke switch 16 is corresponding with adjustable shelf 7, and lower stroke switch 17 is corresponding with ratchet bar 13 lower surfaces.Upper stroke switch 16 and lower stroke switch 17 gather locking and unlocking signal, and feed back to operating console, avoid maloperation.
The lower end of described ratchet bar 13 is provided with running roller 18.18 pairs of ratchet bars 13 of running roller play and support and spacing effect, and when ratchet bar 13 advances or pulls out, running roller 18 rolls, and frictional resistance is little, and ratchet bar 13 advances or pulls out laborsaving.
