Integrated all-purpose lock cylinder and assorted key

Abstract

The invention discloses an integrated all-purpose lock cylinder and an assorted key. The integrated all-purpose lock cylinder comprises an anti-drilling cap, a plunger latch, a stand column, an outersleeve, an inner sleeve and a plurality of functional sheets, wherein the outer sleeve is fixed in a keyhole of a lock body; the inner sleeve is nested in the outer sleeve and can rotate; the tail endof the inner sleeve is provided with a bulge; the anti-drilling cap is extruded out of the front end of the outer sleeve and can rotate so as to prevent the inner sleeve from moving forwards; throughsprings, all functional sheets are tightly pressed until the functional sheets return to a zero position; the stand column is fixed on the center of the tail part of the inner sleeve; a movable sheetcan rotate around the stand column at will, and a fixed sheet string can axially slide on the stand column; and the plunger latch can move among the inner sleeve, the outer sleeve and the groove of the movable sheet. According to the integrated all-purpose lock cylinder disclosed by the invention, through structure innovation, the universalization, the miniaturization and the standardization of amechanical lock cylinder can be realized, safety and reliability are improved, the integrated all-purpose lock cylinder can be automatically produced, production efficiency is improved, a fault rateis lowered, and cost is lowered.

Description

Technical field [0001] The invention relates to the technical field of mechanical locks, in particular to an integrated universal lock core and matching keys. Background technique [0002] All mechanical locks follow the principle of dislocation locking. The key slot of the active part (key) and the protrusion of the passive part (locking part) are engaged with each other to make the misalignment complementary to realize unlocking; when the key is pulled out, the locking part is dislocated to realize atresia. No matter if it is a pin lock, a reed lock, or a keyless turntable combination lock, there is no exception. [0003] The lock cylinder is the core of the mechanical lock. To increase the key quantity, more parts must be added, such as the pin and matching spring of the pin lock, and the lock piece and the matching spring of the reed lock, but the current lock cylinder space is limited , Part of the parts must be installed in the lock body to accommodate all the locking funct...

AI Technical Summary

Problems solved by technology

Taking the commonly used standard mortise lock as an example, the maximum diameter of the lock hole is only 14mm, and theoretically the number of keys should not exceed 5×4! Some springs and pins or locking pieces can only be arranged on the lock body, so the key repetition rate is less than or equal to 1 / 1000 has become an industry standard; traditional mechanical lock cylinders are assembled by hand, the more complicated the higher the cost, the lower the output and the easier it is break down

This is the fundamental reason why the lock cylinder cannot become an independent universal part
