Abstract

The invention discloses a lock cylinder structure which comprises a lock cylinder body; a keyhole for inserting a key is arranged in the lock cylinder body; a hollow cavity is arranged in the lock cylinder body; a linkage plate is arranged in the hollow cavity; upper positioning slots are respectively arranged at the upper end of the linkage plate along the direction of the keyhole, and lower positioning slots are respectively arranged at the lower end of the linkage plate along the direction of the keyhole; upper billiard holes are sequentially distributed in the radial direction in the lock cylinder body above the linkage plate, and lower billiard holes are sequentially distributed in the radial direction in the lock cylinder body below the linkage plate; lower billiards are located in the lower billiard holes, with the upper ends propping in the lower positioning slots; upper billiards are located in the upper billiard holes, with the lower ends propping in the upper positioning slots; and the upper ends of the upper billiards match with lock body billiards. The lock cylinder structure provided by the invention has good anti-prising performance and high safety.

Description

technical field [0001] The invention relates to a lock cylinder structure. Background technique [0002] The existing lock core includes a core body, the core body is provided with a keyhole for a key to be inserted into, pinholes are radially arranged in the core along the direction of the keyhole, and the pinholes of the lock core can be slid up and down in the pinholes Inside; the lock core is rotatably set on the lock body, and the lock body is provided with a pin groove for the lock body, and a spring is installed at the bottom of the pin groove, and the spring is supported on the pin of the lock body, and the pin pin of the lock body Cooperate with the pins of the lock cylinder; when the key is inserted into the keyhole, each pin of the lock cylinder cooperates with the pins of the lock body, and the contact part between the pins of each lock cylinder and the pins of the lock body is just the contact surface of the lock body and the lock cylinder On the other hand, no...
