Anti-theft idling vane lock

Abstract

The invention provides an anti-theft idling vane lock which comprises an idling vane lock and a key. The idling vane lock comprises a lock shell, a lock cylinder and a joint, wherein a lock shell fastening slot and a lock cylinder fastening slot are correspondingly arranged on the lock shell and the lock cylinder respectively. The front end of an L-shaped clutch can move between the lock shell fastening slot and the lock cylinder fastening slot, the rear end of the L-shaped clutch is in clutch connection with the joint which is connected with a rotating part used for driving an unlocking mechanism. A rod control mechanism is arranged at the rear end of the lock cylinder and is abutted to the clutch. The clutch is driven by the key through the rod control mechanism. A function sheet driving the rod control mechanism is mounted at the tail end of the key, a starting device driving the function sheet of the key is arranged in the lock cylinder, and the function sheet can drive the rod control mechanism to control the clutch under action of the starting device. The rod control mechanism is added in an existing idling vane lock, dual control of the clutch is realized, and dual matching of key teeth and the function sheet of the key is required to unlock, so that the anti-theft idling vane lock has the advantages of high safety and excellent anti-theft performance.

[0002] Existing idling blade locks, as disclosed in the patent application number 200710053646, are made up of a lock body, a lock core, some blades, a clutch bar, a rotor, a lock hook, and a toggle tongue. The lock hook longitudinal groove, the lock body has a pair of springs facing the lock hook longitudinal groove, the lock cylinder is provided with a lock hook accommodation groove, the blades are arranged in the lock cylinder in turn, each blade is provided with a gap and a corresponding reset piece , the rotor is set at the end of the lock cylinder, and the end surface of the rotor is provided with a horizontal groove for the lock hook. The lock hook is L-shaped. The connection locks the lock; when the matching key is inserted into the lock cylinder, the key drives the gaps of all the blades to align, and the lock cylinder is rotated so that the bottom end of the clutch bar falls into the gaps of all the blades, which releases the supporting effect of the clutch bar on the lock hook , the spring pushes the front end of the lock hook directly into the lock hook accommodation groove of the lock cylinder, and inserts the end of the lock hook into the lock hook horizontal groove of the rotor, so that the rotor and the lock hook are connected, and then continue to rotate the lock cylinder to drive the rotor to rotate The lock is opened; after the key is pulled out, all the blades are reset under the action of the reset part, and the end of the clutch bar is pushed out of the gap of the blade, and then the front end of the lock hook is reset into the lock hook longitudinal groove of the lock body, and the end of the lock hook is retracted Away from the rotor and not connected to the rotor, so that the lock is in a locked state; when a non-matching key or other objects are inserted into the lock cylinder, the lock cylinder can still rotate, but because the front end of the lock hook cannot fall into the lock hook receiving groove of the lock cylinder , so that the end of the lock hook cannot be inserted into the horizontal groove of the rotor lock hook, the lock hook and the rotor are not connected, the lock cylinder can only be idling, and the rotor cannot be driven to rotate, and the lock cannot be opened

The disadvantage of the idling blade lock of this structure is that in the actual use process, there are still situations of illegal opening, and the anti-theft performance needs to be further improved.
