Block.
Further: the lock-switch of solution outdoors has release lever, which is equipped with unblock button,
The release lever inside upper part is connected with link mechanism by pin shaft, which is connected in turn by pin shaft
Link mechanism and soft-axle fixation bracket, door lock for cab connecting rod is connected on the link mechanism, and the tube core of the flexible axle stretches out
End is connected and fixed with the soft-axle fixation bracket, and the guiding hose of the flexible axle is fixed in the locating slot of the link mechanism,
The tube core extension end of the flexible axle is connected and fixed with the bracket, and the guiding hose of the flexible axle is fixed on the link mechanism
In locating slot.
Due to the adoption of the above technical scheme, compared with prior art, the present invention having the following beneficial effects:
1, since flexible axle head end and door limiting lock connect, flexible axle tail end is connect with solution lock-switch outdoors, and solution lock-switch is interior in door
Sliding block is located at door limiting lock and is solved in the flexible axle section between lock-switch outdoors, i.e. optimization flexible axle, can be in interlude by door
Lock solution switch driving also can realize double drive function by solution lock-switch driving outdoors in end, and the inventive structure is succinct, beautiful,
It is connected and is driven by flexible axle between door limiting lock, solution lock-switch, it respectively can be with flexible arrangement in different location；The door solution of driver's cabin
Lock handle is usually placed in the height that people's standing ground can operate, and is placed on the more equal labour-saving position of switch gate, meets
Arrive at a station on the spot face unlock door limiting lock the case where when, hold door lock for cab handle can realize unlock door limiting lock, close the door
Consistent operation.
2, link mechanism and soft-axle fixation bracket, connecting rod machine are connected in turn by pin shaft due to release lever inside upper part
Door lock for cab connecting rod is connected on structure, tube core extension end and the soft-axle fixation bracket of flexible axle are connected and fixed, and are driven by optimization
The link mechanism of room door release lever, the driving of flexible axle end is integrated on cab door release lever, realizes cab door
The dual control of release lever, can control door lock for cab respectively and door limiting is locked, and not need to arrange additional tripper for door
The unlock of limiting lock.
