Description

A dual-drive pressing device applied to an intelligent lock clutch

technical field

The utility model relates to a pressing device for a clutch of a lock, in particular to a dual-drive pressing device applied to an intelligent lock clutch.

Background technique

At present, in locks, especially door locks, in order to avoid direct unlocking of the outer handle, a clutch is usually provided between the outer handle and the unlocking shaft. Correctly, the clutch is connected with the outer handle and the unlocking shaft to realize external unlocking. At present, most of the commonly used clutches are pin-type clutches, and the clutch function is realized by pressing the pin of the pressing device (such as patent number: CN201520033348.0, etc.). Currently, the pin-type clutch Most of them are used with electronic unlocking devices. Most of the pressing devices are electric pressing devices. However, when the electronic equipment fails, the unlocking cannot be realized. For this reason, mechanical unlocking needs to be considered. At present, the solution is to configure an additional pressing mechanism The mechanical lock cylinder pushes the entire bolt pressing device to move the pressing bolt. Although this solution solves the problem of mechanical unlocking, but because the bolt pressing device can move as a whole, its stability is poor, and it is easy to get stuck, and the bolt pushes up. The pressure device has a large target, and is easily moved by the thimble inserted into the lock, and pressed against the latch to unlock, so the anti-theft and anti-prying performance is poor.
