Embodiment Construction

[0024] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0025] Such as Figure 1 to Figure 6 As shown, the present invention provides a preferred embodiment of an emergency gearbox.

[0026] Specifically, an emergency gearbox, the emergency gearbox is installed on a lock, and is used to drive the lock to unlock. The emergency gearbox includes a gearbox body 10, a power output gear set, an automatic power input gear set driven by a motor 31 in the gearbox body 10, and a clutch between the power output gear set and the automatic power input gear set. The emergency gearbox also includes an emergency assembly. In the power failure state, the emergency assembly drives the clutch assembly to complete the clutch operation. At this time, the automatic power input gear set does not drive the power output gear set to output power, but changes The power output gear set is driven by the emergency compone...

Abstract

The invention relates to the field of door lock accessories, in particular to an emergency speed changing box. The emergency speed changing box comprises a speed changing box body, a power output gearassembly, an automatic power input gear assembly, a clutch assembly, an emergency knob, a clutch matching piece connected with the emergency knob and a driving gear, when the clutch matching piece rotates along with the emergency knob, the clutch assembly can be driven to be in a separation or combination state; the driving gear comprises an engaged region and an avoidance region, the engaged region is engaged with the power output gear assembly, and the avoidance region is separated from the power output gear assembly; when the driving gear rotates to be engaged with the power output gear assembly along with the emergency knob, the clutch matching piece drives the clutch assembly to be in a separated state; and when the driving gear rotates to be separated from the power output gear assembly along with the emergency knob, the clutch matching piece drives the clutch assembly to be in a combined state. When in a power failure state, the emergency knob is twisted, then, separation and combination and unlocking operation can be finished synchronously, and the emergency speed changing box is quite simple and convenient to operate.

Description

technical field [0001] The invention relates to the field of door lock accessories, in particular to an emergency gearbox. Background technique [0002] At present, the quality of anti-theft doors on the market is uneven. Locks are one of the important considerations for the anti-theft safety performance of doors. Almost all locks are mechanical. The main bolt is cylindrical or square, and the stroke in the lock body is twisted by external force. block to achieve the purpose of switching locks, this type of lock body has a complex structure, many accessories, and a high failure rate, and it can no longer meet the matching requirements of the emerging smart locks. [0003] The commonly used smart lock is different from the traditional mechanical lock. It is a lock that can be more intelligent in terms of user identification, security, and management. It uses intelligent remote control to control the opening and closing of the anti-theft door. [0004] However, the existing s...
