Abstract

The invention relates to a mortise lock and a key thereof, which belong to a door lock and a key device. The mortise lock comprises a lock body, an inner lock core column, an outer lock core column, an inner clutch, an outer clutch and a plectrum, wherein the plectrum is placed between the inner clutch and the outer clutch. The invention has the essential that an inner hole is arranged at the outer end part of the inner lock core column, a spring is arranged in the inner hole, and the outer end part of the spring is supported on the inner end surface of the inner clutch; the mortise lock is provided with an ordinary key and a knob key capable of being inserted into the inner lock core column, and the length of the knob key capable inserted into the inner lock core column is shorter than the length of the ordinary key inserted into the outer lock core column; the inner lock core column and the outer lock core column are provided with two rows of marbles, wherein the marbles on the upper row control an upper locking key, and the marbles on the lower row control a lower locking key; and a clamping spring and a steel column are arranged at the outer end part of the outer lock core column. The mortise lock has the advantages that the prying, drilling and technical unlocking capabilities are strong, the mortise lock not only can be unlocked in a single direction, but also can be converted into bidirectional unlocking, and the mortise lock has safe and convenient use for users.

Description

technical field [0001] The invention relates to a door lock and a key device, especially a mortise lock and a mortise lock which is locked by a lock key, has a large number of marbles, and has strong anti-prying, anti-drilling and anti-technical opening capabilities, which can be opened in one direction or can be converted into two directions. key.

AI Technical Summary

Problems solved by technology

All in all, the existing mortise locks have poor anti-theft performance and are easy to be opened by technology, forcibly pried open or damaged by electric drills.

Mortise locks with one-way opening have worse anti-theft performance, while mortise locks with two-way opening are very troublesome to use
