Abstract
The invention discloses an anti-theft lock cylinder with a three-in-one structure. The anti-theft lock cylinder with the three-in-one structure comprises a lock cylinder shell, a lock liner which is arranged inside the lock cylinder shell and can rotate along the lock cylinder shell and a dial wheel which is installed on the lock liner. A keyhole is arranged in the lock liner, and a key is inserted into the keyhole. A plurality of pin tumbler holes which are lined up in rows and a finger ball groove are formed in the lock liner along the axial direction of the lock liner, and the pin tumbler holes and the finger bead groove are all communicated with the keyhole. A plurality of spring holes which are lined up in rows are formed in the lock cylinder shell along the axial direction of the lock cylinder shell, and the spring holes and the corresponding pin tumbler holes are communicated to form channels. Joggle joint structure lock cylinders and mother-sub telescopiform lock balls are respectively arranged in the channels. One end of a spring exerts force onto the joggle joint structure lock cylinders or the mother-sub telescopiform lock balls, and the other end of the spring exerts force onto a sealing ball which presses the lock cylinder shell. According to the anti-theft lock cylinder with the three-in-one structure, three different anti-theft mechanisms are adopted, technical opening difficulty is added, and anti-theft performance is high.
