Abstract
The invention is suitable for the technical field of door lock devices, and discloses a breakage-proof European type lock cylinder. The breakage-proof European type lock cylinder comprises a lock body, a lock cylinder body arranged in the lock body, and a lock body stirring fork used for opening and closing the lock body. The lock cylinder body is composed of an outer lock cylinder main body and a twisting lock cylinder main body. The outer lock cylinder main body and the twisting lock cylinder main body are arranged in two cavities in the lock body respectively. One end of the twisting lock cylinder main body is connected with the outer lock cylinder main body, and a twisting part is arranged at the other end of the twisting lock cylinder main body. The two sides of the lower end of the lock body are each provided with marble holes used for installing marble beads and marble springs. A positioning hole is formed in the twisting lock cylinder main body. The second marble hole, located at one end of the twisting lock cylinder main body, on the lock body is matched with the positioning hole. A steel bead and a cylindrical positioning bead used for supporting the steel bead are arranged in the second marble hole. The steel bead is fixedly arranged in the second marble hole through the cylindrical positioning bead, the marble spring and a bolt. The breakage-proof European type lock cylinder is reasonable in structure, the safety performance of a lock head is improved through a pull-apart groove and other structures, and the efficient protection function is achieved.
