The invention discloses a lock adopting a leaf pin idling lock core structure and a key. A locking side post matching with a V-shaped groove on a leaf pin is arranged on the front lock core of the lock, a sliding block groove communicates with the locking side posts. A lockpin is arranged in the lockpin sliding slot on the rear lock core. The sliding block radially matching with the locking side post is arranged in a locking side post groove. At least two contact parts with inclines are provided along the axial direction of the lock core between the sliding block and the locking side post. One end of the sliding block is positioned in the sliding block slot and is contacted with the lockpin on the rear lock core. One side of the leaf pin is provided with a protruding part matching with the boss with bits on the key. Only one side of the key is provided with the boss of a thinner thickness. The lock is capable of reducing the mutual opening rate and preventing a thicker tool from being inserted in a lock hole for violent unlocking.

The invention discloses an anti-theft lock. The anti-theft lock comprises a lock shell and a lock cylinder. A lock shell hole and a lock shell groove are formed in the lock shell. The lock groove is formed in the side wall of the lock shell hole. The lock cylinder is arranged in the lock shell hole and can rotate freely in the lock shell hole. Marble grooves, a lock rod groove and a lock plate groove are formed in the side wall of the lock cylinder. The multiple marble grooves are formed in the lock cylinder. A marble assembly is arranged in each marble groove. Each marble assembly comprises a marble rod and a spring. A lock plate is arranged in the lock plate groove. The lock plate is in contact with the marble rods. Containing grooves are formed in each marble rod. A lock rod is arranged in the lock rod groove. The lock rod is in contact with the lock plate. The lock rod enters or protrudes out of the surface of the lock cylinder under the effect of the lock plate. By the adoption of the anti-theft lock, the key quantity is increased, the technical unlocking can be prevented effectively, and the safety performance is enhanced greatly; and besides, the marbles are designed in a rod shape, the strength is larger, the situation that the lock cylinder is twisted forcedly with a tool and the marble assemblies in the lock are catastrophically destroyed is avoided, and thus the forced unlocking is prevented effectively.

The invention discloses a lock with a leaf pin idling lock core structure, which comprises a front lock core in the lock body. A plurality of leaf pins are arranged along the axis on the front lock core, locking side posts matching with a V-shaped groove on the leaf pins are arranged in the locking side post grooves thereon, step-shaped grooves are provided on the locking side post, clamping plates and fixing parts matching with the step-shaped groove on the locking side post are arranged in the upper part of the locking side post. A radial return spring of the locking side post is arranged between the fixing parts and the locking side posts. The middle part on one side of the leaf pin is provided with a protruding part matching with the boss with the bits on the key. Only one side of thekey is provided with the boss of a thinner thickness. The lock of the invention has simple structure, less components and easy processing, and is capable of preventing a thicker tool from being inserted in a lock hole for violent unlocking.

An idling lock comprises a lock cylinder, an engineering vane, a common vane, an engineering key and an owner key. The lock cylinder is provided with a spring, a spring head can extend into a vane groove and abut against the end face of the engineering vane, the engineering vane is provided with a W-shaped notch, and engineering key teeth are not contacted with the engineering vane, but owner key teeth are contacted with the engineering vane. After the owner key is inserted, the engineering vane moves, the spring head is separated from a lower frame edge of the engineering vane and is buckled on the side face of a protruding block along the protruding block, and the engineering vane can not recede so that after the owner key opens the lock, the engineering key can not be used for unlocking. By means of the design of the idling structure, the situation that the engineering key is changed into the owner key for use is effectively prevented. Besides, due to special-shaped design of the engineering vane and the engineering spring and special arrangement of a special-shaped strip and a limiting strip, any kind of technical unlocking can be prevented. Besides, an anti-drill bolt, an anti-drill card and an embedded block are arranged in each lock, so any violent unlocking can be prevented.

The invention relates to a security encryption matrix contact type electronic lock key and relates to the field of electronic locks. The key comprises a matrix key board and a key casing, wherein a fingerprint module and a display screen are arranged on the lateral edge of the key casing, and a control button is arranged at the upper end of the key casing; a key MCU is arranged in the key casing,and the key MCU is respectively connected with a power management module, a storage module, a fingerprint module, a contact communication module, a Bluetooth module, an anti-disassembled detection module, a driving motor module and a display and sound module; after verification of the fingerprint module, the driving motor module is started to pop the matrix contact key out; after detection error times of the fingerprint module exceed preset times, password files stored in a FLASH are automatically formatted; thus, the problems of safely encrypting the electronic lock and preventing the electronic lock from being cracked for procedures or chip interfaces are solved, physical encryption can prevent a password of the electronic lock from being cracked through the interfaces, the electronic lock is effectively prevented from being unlocked violently, and data cracking unlocking prevention is improved based on preventing technological unlocking.
