Problems solved by technology

In order to prevent the landing door lock from being opened randomly, the height of the landing door lock hole is usually higher. When the height of the landing door lock hole is greater than 2000mm, the maintenance personnel may not be able to reach the position of the lock hole when unlocking with a common unlocking key, or The posture of the body is seriously deformed when unlocking the lock. Once the landing door is opened, the danger of falling into the well is very easy due to the change of the center of gravity of the body.

Abstract

The invention relates to an unlocking key applied to an elevator floor door lock. The unlocking key comprises an unlocking component (1), a fixed connecting part (2), a movable connecting part (5) and a locking part (4), wherein the fixed connecting part (2) is fixed at the unlocking component (1); the movable connecting part (5) which is flexibly matched with the fixed connecting part (2) along the length direction of the fixed connecting part (2); the locking part (4) is used for connecting the fixed connecting part (2) with the movable connecting part (5) in a locking manner. Compared with the prior art, the unlocking key disclosed by the invention can be regulated in length by virtue of a flexible design of the fixed connecting part and the movable connecting part so as to satisfy unlocking demands of floor door keyholes which are different in height; the unlocking key disclosed by the invention is ingenious in structural design, and is convenient to carry by being contracted to a minimum size when not used.

Description

technical field [0001] The invention relates to a landing door unlocking device of an elevator, in particular to an unlocking key for unlocking a landing door of an elevator. Background technique [0002] Floor door locks are installed on the landing doors of the elevator. If you want to open the landing doors during maintenance or emergency rescue, you need to use a special unlock key to open them, so as to prevent people from falling into the shaft. In order to prevent the landing door lock from being opened randomly, the height of the landing door lock hole is usually higher. When the height of the landing door lock hole is greater than 2000mm, the maintenance personnel may not be able to reach the position of the lock hole when unlocking with a common unlocking key, or The posture of the body is seriously deformed when unlocking. Once the landing door is opened, the danger of falling into the well is very likely to occur due to the change of the center of gravity of the ...
