<p>A blade lock structure embedded into a spring lock core comprises a shell formed of an upper cover (4) and a lower cover (3) that are fastened with each other, a movable main lock bolt (2) in the shell, a blade (1) linked with the main lock bolt (2), and a blade locating plate (7) closely attached to the blade (1). The upper cover (4) and the lower cover (3) are provided with blade key holes (6) right opposite the blade (1). A spring lock core (36) is arranged in the shell. The center of the key hole (8) of the spring lock core (36) and the center of the blade key holes (6) of the upper cover (4) and the lower cover (3) are on the same axis. Also disclosed is a key used together with the blade lock structure embedded into a spring lock core, comprising a key body (33) and blade lock teeth (34) symmetrically arranged at two sides of the front end thereof. The key body (33) between the blade lock teeth (34) at the two sides is provided with spring teeth (35) fitted with the spring lock core (36). Through the combination of spring lock coding and blade coding, the key is hard to copy, and the blade lock structure embedded into a spring lock core has a good technical-opening prevention effect.</p> |
