Clutch device of electronic lock

Abstract

The invention discloses a clutch device of an electronic lock, and relates to the improvement of a clutch device structure of the electronic lock. The invention provides the clutch device which has a simple structure, safety and reliability and is easy to reform the electronic clock. The clutch device comprises a lock body, a lock bolt, a lock bolt connecting rod and a self-locking piece mechanism, wherein the lock bolt connecting rod is connected with the lock bolt through a shaft; and the self-locking piece mechanism is connected with the lock bolt and consists of an upper self-locking piece, a side self-locking piece and a lower self-locking piece. The structural features of the clutch device of the electronic lock are that: an electromagnet is arranged at the top of the lock body; an inner shifting piece, an inner shifting block, and an outer shifting block and an outer shifting piece which can rotate on the inner shifting block relatively are arranged in an inner handle hole below the electromagnet in turn; a clutch block is arranged on the inner shifting block, wherein the clutch block is provided with a rotating shaft and the end of the clutch block is provided with a clutch opening; the clutch block is attracted to one end, provided with a magnet, of the shifting piece on the shaft; and the other end of the shifting piece is connected with the electromagnet.

Description

Technical field: [0001] The invention belongs to the technical field of locks for fixed building parts in the International Patent Classification, and more specifically relates to an improvement in the structure of an electronic lock clutch device. Background technique: [0002] At present, door locks sold on the market can be roughly divided into two types, namely mechanical locks and electronic locks. The so-called mechanical lock means that the parts in the entire lock body are mechanically connected, and this type of door lock is widely used in daily life; among them, the usual structure of the unlocking device of the mechanical lock includes an inner paddle, an outer paddle and an inner paddle. 1. The shift block between the outer paddles; although the mechanical lock does not need to be powered, its disadvantage is poor safety, mainly in the fact that the key to open the mechanical lock is easy to copy, but the electronic key used to open the electronic lock is not eas...

Problems solved by technology

The general structure of the motor-type electronic lock unlocking device is: the motor drives the gear to rotate, pushes the telescopic column into or out of the clutch device, and enters the clutch device through the telescopic column to realize the unlocking of the outer handle. The internal structure is relatively complicated; If the power is cut off and the clutch device fails when it is not reset, the outer handle of the door lock will be able to unlock with or without authorization.

In addition, the unlocking methods of some existing electromagnetic electronic locks are difficult to implement because the unlocking mechanism directly acts on the lock tongue, the driving current is too large, and the intermediate clutch device is lacking.
