Problems solved by technology

[0002] Most of the current tumbler locks use the locking column as the locking device to control the rotation of the lock cylinder. Its anti-violence opening and anti-technical opening performance is better, but in its classic structural design, only a row of tumblers and pins can be arranged because the lock cylinder is integral. Locking column fit, the amount of key is relatively limited
If the lock cylinder is designed as a sheet-like superimposed structure to install two rows of marbles, the processing efficiency is too low and the manufacturing cost is high

Abstract

The invention discloses a combined type spring lock, comprising a lock sleeve, a lock cylinder and a locking piston which is longitudinally installed along the axis of the lock cylinder, wherein two ranges of longitudinal springs are longitudinally installed in the lock cylinder, two lateral springs are installed between the two ranges of longitudinal springs in parallel, and the inner side of the locking piston can only be positioned in the clearance between the two lateral springs when the spring lock is in an opening state; and the invention further discloses a key which is matched with the combined type spring lock, wherein two ranges of teeth are arranged on the front surface of a key piece, and the teeth have the angles matched with the longitudinal springs. The combined type springlock and the key of the invention realize the purpose of opening a lockset through the interaction and displacement of the two ranges of longitudinal springs and two lateral springs, simplify the structure of the spring lock, and improve the key amount and the safety of the spring lock.

Description

technical field [0001] The invention relates to a lock, in particular to a tumbler lock and a key. Background technique [0002] Most of the current tumbler locks use the locking column as the locking device to control the rotation of the lock cylinder. Its anti-violence opening and anti-technical opening performance is better, but in its classic structural design, only a row of tumblers and pins can be arranged because the lock cylinder is integral. The locking column cooperates, and its key quantity is subject to greater restriction. If the lock cylinder is designed as a sheet-like superimposed structure to install two rows of marbles, the processing efficiency is too low and the manufacturing cost is high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined pin lock and key that can install two rows of vertical pins and two horizontal pins in the integral lock cylinder to improve the key quantity and s...
