Electrical and mechanical separation type door lock

Abstract

The invention discloses an electrical and mechanical separation type door lock. The electrical and mechanical separation type door lock comprises a shell, a motor, an electrical and mechanical separation mechanism, a first driving assembly, a main spring bolt, a second driving mechanism, a latch bolt, a third driving mechanism and a linkage mechanism; the electrical and mechanical separation mechanism comprises a push plate, a first elastic piece, a pushing rod, a locking piece, a limiting rod, a rail and a second elastic piece; when a mechanical unlocking assembly drives the push plate to move, the locking piece can relieve locking with the limiting rod and the mechanical unlocking assembly synchronously drives the linkage mechanism to drive the main spring bolt to retract to the shell; the linkage mechanism at least comprises a prodding piece, a double-sided gear and a rotating piece; a first tooth part, a second tooth part and a limiting column are arranged on the double-sided gear;and after the latch bolt stretches out of the shell, the limiting column finishes a stroke groove and the double-sided gear continuously rotates to drive the rotating piece to synchronously rotate todrive the main spring bolt to stretch out of the shell. The electrical and mechanical separation type door lock is simple, convenient and rapid in operation and convenient to use; the latch bolt stretches out of the shell in advance of the main spring bolt, so the electrical and mechanical separation type door lock is more flexible to use; and the electrical and mechanical separation type door lock is reasonable in integral layout, compact in structure and small in volume.

Description

technical field [0001] The invention belongs to the field of intelligent locks, in particular to an electromechanical separation type door lock. Background technique [0002] At present, the electronic locks on the market include two types with manual unlocking and without manual unlocking. The fully automatic electronic lock without manual unlocking cannot be quickly unlocked manually in an emergency, which brings potential safety hazards, while the fully automatic electronic lock with manual unlocking The structure is complex again, and the automatic motor unlocking mechanism and the manual mechanical unlocking mechanism are separated from each other, resulting in excessive volume of the lock body, or in order to give it space, causing other parts to have limited space and difficult processing. There are also electronic locks with a clutch mechanism between the motor automatic unlocking mechanism and the manual mechanical unlocking mechanism, but it is only suitable for lo...

Problems solved by technology

[0002] At present, there are two types of electronic locks on the market, with manual unlocking and without manual unlocking. The fully automatic electronic lock without manual unlocking cannot be quickly unlocked manually in an emergency, which brings potential safety hazards, while the fully automatic electronic lock with manual unlocking And the structure is complex, the motor automatic unlocking mechanism and the manual mechanical unlocking mechanism are separated from each other, resulting in an excessively large lock body, or in order to give it space, resulting in limited space for other components and difficult processing

There are also electronic locks with a clutch mechanism between the motor automatic unlocking mechanism and the manual mechanical unlocking mechanism, but it is only suitable for locks that are opened separately by a single bolt. If the electronic lock has multiple bolts, it cannot be independently opened. , or the overall size of the lock is larger if implemented
