Mechanical interlocking spring-free anti-theft multiple lock

Abstract

The invention discloses a mechanical interlocking spring-free anti-theft multiple lock. The rear lock cylinder of the mechanical interlocking spring-free anti-theft multiple lock is completely disconnected from a connector and a front lock cylinder; a sliding rod is arranged in a sliding hole formed in the front lock cylinder, while the connector is mounted in a hiding hole; a squeezing block is fixed on the sliding rod; a connecting hole is formed in the front face of the rear lock cylinder, and a connecting tongue is fixed on the rear face of the rear lock cylinder and goes through a via hole; the sliding rod mounted in the sliding hole is arranged in front of a guide spring in the sliding hole; the sliding rod is further mounted in a squeezing groove and the sliding hole; the squeezing block is embedded in the sliding rod in the squeezing groove; the expansion end of the expansion piece is located in the squeezing groove to lock the front lock cylinder; the front lock cylinder is locked by an inclined locking device and a rotary locking device. The mechanical interlocking spring-free anti-theft multiple lock is integrated with mechanical interlocking, hiding, and connection hiding of the front and rear lock cylinders, and therefore, the breaking of inner support locking and the rotating of the rear lock cylinder cannot be realized simultaneously by a theft; even though the inner support locking and the connector parts are damaged violently, only the front lock cylinder can be rotated and the rear lock cylinder cannot be rotated, and consequently, a complete and thorough anti-theft effect is achieved.
