The invention discloses a mechanical interlocking pin-free burglarproof lock. A back lock cylinder is thoroughly disconnected from a connecting body and a front lock cylinder. The front lock cylinder is deadly locked by an expansion piece and a rotation block. In the front lock cylinder, a slide rod is arranged in a slide hole, and the connecting body is disposed in an invisible hole. An extrusion block is fixed on the slide rod. The front face of the back lock cylinder is provided with a connecting hole and the rear face of the back lock cylinder is provided with a connecting tongue which goes through a via hole. The slide rod, in the frontal surface of a guide spring in the slide hole, is mounted in the slide hole. The slide rod is mounted in an extrusion groove and the slide hole. The extrusion block is embedded in the slide rod in the extrusion groove. The front lock cylinder is deadly locked in the extrusion groove by an expansion end of the expansion piece. The front lock cylinder is deadly locked in an inclined groove and an inclined lock groove by the rotation block. The mechanical interlocking pin-free burglarproof lock integrates mechanical interlocking, invisibility, and the connecting invisibility of the front lock cylinder and the back lock cylinder, so that a burglar cannot open an interlocking device and rotate the back lock cylinder, and even if the burglar uses a forcible means to damage an inner supporting lock and a connecting body part, only the front lock cylinder can be rotated and the back lock cylinder cannot be rotated. Therefore, a thorough burglarproof effect is fulfilled.
