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 core structure. Background technique [0002] The existing lock cylinder includes a core body, the core body is provided with a key hole for a key to be inserted, and a pin hole is arranged radially in the core body along the key hole direction, and the lock cylinder pin is slidably installed in the pin hole up and down The lock cylinder is rotatably sleeved on the lock body, the lock body is provided with a lock body pin slot, the bottom of the pin slot is installed with a spring, the spring is pressed against the lock body pin, the lock body pin Match with the lock cylinder pin; when the key is inserted into the key hole, each lock cylinder pin is matched with the lock body pin, and the contact part of each lock cylinder pin and the lock body pin is just the contact surface between the lock body and the lock cylinder It can realize normal unlocking; the existing technical defects are: the use of unlocking tools to move the...
