Abstract

The invention relates to a mechanical combination lock capable of eliminating three technical unlocking hidden troubles for a safety box, relating to a combination lock for a safety box; the mechanical combination lock uses an inner board in parallel and fixedly connected with the door plank of the safety box, a turn-knob shaft sleeve fixed into the inner board and the door plank interlayer of the safety box and extending outwards, a combination wheel assembly rotating on the extending part of the turn-knob shaft sleeve, an unlocking limit wheel matched with a compression spring and in clutch type match with a driving combination wheel, a retractable turn-knob and a lock executing mechanism; the mechanical combination lock eliminates the three hidden troubles of friction type technical unlocking, percussive technical unlocking and measuring dynamic balancing technical unlocking, and has 6.8 million times of dense variables; therefore, the mechanical combination lock becomes the mechanical combination lock with the strongest security at all times and in all lands, and is a novel product in the field. The mechanical combination lock is simple in structure, saves material, has reliable performance and long service life, and can be applied to safety boxes and document boxes in family.

Description

Technical field: [0001] The invention relates to a safe lock, in particular to a mechanical combination lock used in a safe. technical background: [0002] The mechanical combination locks used in the existing general-purpose safes cannot eliminate the hidden dangers of multiple technical openings, and the security is poor and the hidden dangers are large. Invention content: [0003] The purpose of the present invention is to eliminate the hidden dangers of various technical openings, make the combination lock used in safes have comprehensive and deep security, and provide the society with excellent products that are really effective. [0004] The purpose of the present invention is achieved like this: [0005] The lockset is provided with an inner plate parallel to and fixedly connected to the safe door panel, and the knob shaft bushing which is fixed in the interlayer of the inner plate and the safe door panel and extends outwards is rotated on the active part of the ex...
