Power-free idle intelligent lock cylinder

Abstract

A power-free idle intelligent lock cylinder comprises a lock cylinder rear cover, a clutch rear cover and a motor. The lock cylinder rear cover partially stretches into the clutch rear cover, and at least one steel ball is embedded on the peripheral wall of the stretching part. At least one steel ball arc groove is formed in the end face of the side, facing the steel balls, of the clutch rear cover so as to be matched with the steel balls embedded on the lock cylinder rear cover. The motor is arranged in the lock cylinder rear cover, and a motor shaft of the motor is connected with a cam in a sleeved manner. The steel balls abut against the concave face of the cam, so that under drive of the motor, the steel balls are jacked into the steel ball arc grooves of the clutch rear cover through the cam. The cam is further connected with a torsional spring in a sleeved manner, so that the cam is driven to reset. According to the power-free idle intelligent lock cylinder, power and wiring are avoided, mounting is convenient and quick, and cost is low; idle design is adopted in the lock cylinder, and the problem that a lock with the lock cylinder is abnormally opened and closed due to the fact that the lock cylinder is damaged by violence is effectively solved; and the power-free idle intelligent lock cylinder is high in safety.

Description

technical field [0001] The invention relates to an intelligent lock cylinder, in particular to a non-power idling intelligent lock cylinder which is powered by a key, has no power supply for the lock cylinder, and has an idling clutch. Background technique [0002] It can be understood that the existing lock cylinders are mostly divided into these two categories of mechanical lock cylinders and electronic lock cylinders. Among them, the idling of the mechanical lock cylinder is relatively difficult to realize, the processing cost is high, the assembly process is difficult, and the locking point is relatively small, so it is easy to realize technical opening, which cannot realize intelligent and refined management. However, the vast majority of electronic lock cylinders are designed with a power supply, which cannot meet various harsh environments, and the unit price is high. It needs to replace the battery regularly or ensure uninterrupted power supply from an external power...

AI Technical Summary

Problems solved by technology

Among them, the idling of the mechanical lock cylinder is relatively difficult to realize, the processing cost is high, the assembly process is difficult, and the locking point is relatively small, so it is easy to realize technical opening, which cannot realize intelligent and refined management

However, most of the electronic lock cylinders are designed with 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.

Among them, a small number of lock cylinders without power supply adopt a non-idling structure. This type of lock cylinder has only one locking point, and it is easy to suffer violent damage and open the lock abnormally without idling.
