Abstract

A vehicular antitheft lock comprises a tubular lock body, a stem, a cylinder, a plurality of bolts, and an L-shaped key. The outer surface of the key is wrapped with a plastic layer. The middle of the stem is provided with an arc locking notch made of resilient steel and used for fixing a wheel. One end of the tubular lock body is hinged to one end of the stem; the other end of the tubular lock body is provided with a stem notch matching with the other end of the stem; the stem notch is communicated with the cylinder. The outer surface of the tubular lock body is provided with an L-shaped key slot. A bend of the key slot is provided with a key passage leading to the cylinder. The outer wall of the key passage is provided with a cavity in which a magnet is embedded. The bolts are fixedly connected to one end, far away from the key slot, of the cylinder. The tail end of every bolt corresponds to the stem notch; in the stem notch, the tail ends of the bolts are in locking fit with corresponding bolt grooves in the stem. The cylinder is hidden in the tubular lock body, the lock is effectively prevented from being unlocked by a thief using electric drills, forced unlocking tools and the like, and safety is improved.
