The invention provides an anti-misoperation lock. The anti-misoperation lock comprises a lock body, a lock rod, a limiting pin, a two-value chip, an induction structure, a plug pin and an unlocking rotating shaft; the lock rod, the limiting pin and the unlocking rotating shaft are all movably arranged in the lock body; the two-value chip is arranged in the lock body; the lock rod has a locking position and an unlocking position; the limiting pin can limit the lock rod so that the lock rod can be kept at the unlocking position; at least one part of the plug pin can penetrate through a device tobe locked and extend into the lock body; the part, extending into the lock body, of the plug pin, is provided with a locking structure matched with the lock rod; when the lock rod is located at the locking position, the unlocking rotating shaft is rotated through the key to drive the lock rod to move from the locking position to the unlocking position; after the plug pin is separated from the lock body, the induction structure is separated from the induction area of the two-value chip; and the code value of the two-value chip returns to an initial state. With the anti-misoperation lock of theinvention adopted, the problems of poor safety performance and inconvenience in operation of a padlock for a knife switch in the prior art can be solved.
Description
technical field [0001] The invention relates to the field of anti-misoperation knife switch equipment, in particular to an anti-misoperation lockset. Background technique [0002] Currently in the field of rail transit, a padlock is installed at the operating handle of the isolation knife switch in the train parking lot for locking the isolation knife switch. Only after the billing is authorized, the computer key can open the padlock of the isolation switch and pull down the isolation switch to realize opening. Then the computer key could open the door padlock of the maintenance platform, and the maintenance personnel could enter the maintenance platform to carry out the maintenance operation. This kind of anti-misoperation method can prevent misoperation to a certain extent. In the existing knife padlocks, it is usually an ordinary padlock, which can only ensure that the computer key unlocks the padlock with the corresponding code value according to the operation instruct...
