Abstract

The utility model discloses a lock core with tracks in double surfaces and a matched key. Each of two surfaces of the key is provided with two track gullets at appropriate positions. Every two track gullets in each surface are staggered in a different manner. The core is provided with two rows of some clamping component notches at appropriate positions, and each of two sides of the core is respectively provided with a row of locking-sheet sliding grooves, wherein the two rows of some clamping component notches in the core, key grooves and two convex bodies are matched with one another. The clamping component notches in the core are matched with the two track gullets in each surface of the key. The mode of left externally-pressed locking and right internally-pressed locking or left-right simultaneous internally-pressed locking and left-right simultaneous externally-pressed locking significantly improves the anti-theft performance. In addition, the core and the key are simple in structure.
