The invention relates to a motorcycle anti-theft lock, which comprises a lock body, a lock cylinder, a transmission rod, a fixed contact and a moving contact. Mainly, an anti-theft ring is provided between the lock body and the lock cylinder, the outer circle of the anti-theft ring is movably matched with the inner hole of the lock, and the inner hole is movably matched with the lock cylinder; the inner hole of the anti-theft ring at the corresponding position of the pin on the lock cylinder It is made with pin slots; a positioning device is provided between the anti-theft ring and the lock body to prevent the relative rotation of the two; a control switch is provided between the anti-theft ring and the lock body, and the control switch is connected in series with the fixed contact circuit through wires . When the lock picking tool forcibly rotates the lock cylinder, it will drive the anti-theft ring to rotate, and press the control switch to disconnect its normally closed contact, so that the ignition circuit of the motorcycle is in a disconnected state, ensuring that the motorcycle cannot be ignited and started. , Good anti-theft performance, etc., suitable for anti-theft start switch locks of various motorcycles.
Description
technical field [0001] The invention relates to a lock, in particular to a motorcycle electric ignition start lock. The invention is suitable for electric ignition switches of motorcycles. Background technique [0002] Existing motorcycle locks generally consist of a lock body, a lock cylinder, a transmission rod, a fixed contact and a moving contact. The hole is provided with a tumbler slot, and one end of the transmission rod is connected with the end of the lock cylinder, and the other end is connected with the moving contact. When the key is inserted into the lock cylinder, the ends of all pins are retracted into the lock cylinder, so that the lock cylinder can rotate in the lock body. When the key is turned to the set angle, the moving contact coincides with the fixed contact, and the fixed contact is connected. Make the motorcycle ignite and start; when the key is not inserted into the lock cylinder, the marble protrudes from the outside of the lock cylinder under th...
