Passive idle lock cylinder

Abstract

The invention discloses a passive idle lock cylinder in the technical field of lock cylinders. The passive idle lock cylinder comprises a lock cylinder front cover, a lock cylinder rear cover and an electronic key. Two groups of steel balls are embedded into a radial through hole in the left end of the lock cylinder rear cover; a clutch is connected to the left end of the lock cylinder rear cover in a sleeving way; the two groups of steel balls are connected to the upper side and the lower side of an inner cavity of the clutch in a clamping way; dowels and locating pillars are embedded into the upper side and the lower side of the lock cylinder rear cover; the dowels are located at the right sides of the locating pillars; a cam is arranged at the left side of an inner cavity of the lock cylinder rear cover; a torsional spring is connected to the right side of the cam; a cam locating plate is connected to the right end of the torsional spring; and the right side of the cam locating plate is riveted with a left side wall of a motor. The passive idle lock cylinder has no power supply inside, can be idled to prevent violent damage, has a lock operation recording function, adopts monopole communication, can realize authority management through a backstage cloud system, can be suitable for various severe environments, and is wiring free.

Description

technical field [0001] The invention relates to the technical field of lock cylinders, in particular to a passive idling lock cylinder. Background technique [0002] With the progress of society and the development of science and technology, the current lock cylinders are mainly divided into two categories: mechanical lock cylinders and electronic lock cylinders. The mechanical lock cylinder is difficult to assemble and has fewer locking points. It is easy to realize technical opening, but it is impossible to record the opening and closing status of the lock. Almost all existing electronic locks are designed with external power supply, which cannot meet various harsh environments, and the unit price is high. It needs to replace the battery regularly or ensure the uninterrupted power supply of the external power supply. The initial installation requires wiring and regular special maintenance. For multi-pole communication, the stability of two-pole or multi-pole communication...
