It is flexibly connected with circuit switch 110；Specifically, locating part 200 can be movable in carriage 100, and the movable switch can be with institute
Circuit switch 110 is stated to be movably connected, that is to say, that locating part 200 is movable in carriage 100 so that switch re-pack 220 with it is described
Relative motion occurs for carriage 100, so that switch re-packs and 220 is movably connected with the circuit switch 110, in this embodiment
In, switch re-pack the 220 contacts circuit switch 110 when, lift circuit is off-state, at this point, elevator cannot be manipulated artificially
Operation up and down, switch re-pack 220 disengagings and when the circuit switch 110 contact, and lift circuit be the state being connected to, at this point, can
Artificial manipulation elevator is run up and down.Circuit switch 110 can be normal open switch, or normally closed switch.
Plate 300 is provided with the limiting slot 310 protruded into for locating part 200.Plate 300 and the cooperation of locating part 200 can be to sedan-chairs
Compartment 100 limits, and specifically, locating part 200 is inserted into the limiting slot 310, and the position of locating part 200 is defined, and then limits
The position of the fixed carriage 100.
When limiting to carriage 100, the locating part 200 is protruded into the limiting slot 310, at this point, carriage 100
Position is defined, may be to carriage 100, locating part 200, plate 300 if operator's maloperation manipulation elevator is run up and down
Or even entire elevator belt is damaged；And the utility model controls the on-off of lift circuit by circuit switch 110, can avoid operation
Personnel misoperation and damage carriage 100, locating part 200, plate 300 and elevator, specifically, the switch re-packs 220 and institute
It states the contact of circuit switch 110 and circuit switch 110 is opened or closed；In this embodiment, institute is limited using plate 300
