Blade lock head and door lock using same

Abstract

The invention provides a blade lock head. A plurality of blades are arranged in a shell of the lock head and provided with reset springs. Clamping teeth are arranged in the blades. A bolt plate is provided with thumbing teeth and locking columns. A key is provided with thumbing points and concave-convex tables. The concave-convex tables of the key press the blades to move, the clamping teeth in the blades are forced to avoid passageways for the locking columns to move, the thumbing points of the key drive the thumbing teeth on the bolt plate to make the bolt plate move, and when the concave-convex tables of the key leave the blades, the blades reset under the effect of the reset springs. A locking column movement passageway forming mechanism is arranged in the blade lock head and is driven by a start component outside the blade lock head to force the clamping teeth in the blades to avoid the locking column movement passageways so that the locking columns on the bolt plate can move. A door lock using the blade lock head can be rapidly closed outdoors and can be rapidly opened and closed indoors, and use is quite convenient. The wide application of the blade lock head in mechanical mortice door locks, mechanical automatic door locks and electronic door locks is facilitated.

Description

technical field [0001] The invention relates to a blade lock head and a door lock matched with it. Background technique [0002] At present, electronic and fingerprint intelligent master locks are often installed on safes and treasury doors, in order to solve the problem that they cannot be used normally when power failures or electronic intelligent system failures occur. Existing electronic and fingerprint intelligent master locks are equipped with emergency opening locks with mechanical structures. For example, Chinese Patent No. 201520034012.6 proposes "a mechanical emergency lock". But this mechanical emergency lock is installed on the outside of the door body, when the electronic lock shell is forcibly pulled down, as long as the transmission lever 6 is replaced with a flat iron, the electronic lockset can be opened. Therefore, the anti-theft performance of this mechanical emergency lock is very unsatisfactory. Another example is the "ABB blade engineering lock" prop...

AI Technical Summary

Problems solved by technology

But it has the following deficiencies: 1. The structure of the above-mentioned blade engineering lock cannot be applied to electronic door locks and automatic door locks with quick-opening and quick-locking functions

2. When the above-mentioned blade engineering lock is unlocked and locked, it needs to be turned several times with a key, which is very inconvenient to operate

3. When the above-mentioned blade engineering lock is partially damaged or the key is lost, the entire engineering lock needs to be replaced, which is inconvenient for maintenance
