Abstract
The utility model belongs to padlock technical field especially is a kind of anti-knock double-opening padlock, including lock body and lock ring, the top of lock body is equipped with the through hole of symmetrical distribution, the both ends of lock ring are respectively fixedly installed with the lock beam of plug-in installation in the inside of through hole, the outside of lock beam is equipped with lock hole. This kind of anti-knock double-opening padlock, by reverse rotation rotating lock core, release traction rope, under the action of traction spring, lock catch in lock body slide and enter lock hole, complete locking, in this process, the rotation of rotating lock core can drive extension column to rotate, further drive limit rod to rotate, and the displacement of lock catch can drive limit block to move synchronously, after lock catch inserts into lock hole, limit rod rotates to with limit block on the same vertical plane, limit rod and limit block mutually abut, so as to avoid the phenomenon that lock catch rebounds when being subjected to external force to knock lock body side, so as to improve the safety performance of lock body.
