Novel antitheft lock head and key matched with same

Abstract

The invention provides a novel antitheft lock head and a key matched with the same. The novel antitheft lock head comprises a lock body provided with a lock cylinder, and the key. The lock body is shaped like a box. A drive block used for driving the key to conduct unlocking is arranged at the bottom in the lock body. A lock groove for the key to be inserted therein is formed in one side of the drive block. A fixing block locking the lock cylinder through a marble assembly is arranged above the lock cylinder. The key is shaped like a card. Key grooves which are inconsistent in depth and irregularly arranged are formed in the front face of the key. The key is moved to the position below the marble assembly through the drive block to be matched with the marble assembly, and therefore the lock cylinder can be pushed to achieve unlocking when the key continues to be moved. The novel antitheft lock head is reasonable in design and convenient to use. Due to the adoption of the structure, movement of the lock cylinder is stopped by the marble assembly, and locking is achieved; in the unlocking process, the key is inserted into the lock groove of the drive block from an insertion hole of the lock body, the key is driven by the drive block to move to the position below the marble assembly till second marbles fall into the key grooves, the lock cylinder is pushed to move while the key continues to be moved, and then unlocking is achieved; and unlocking difficulty is greatly improved, the antitheft coefficient is quite high, and the novel antitheft lock head and the key are worthy of wide application and popularization.
