A multifunctional ratchet clutch device

Abstract

The invention discloses a multifunctional ratchet wheel clutch device which comprises a clutch device body, a ratchet wheel device and an unlocking and locking device. A shaft drum and a shaft disc are coaxially and fixedly connected to form a rigid body. A space is reserved between the two inner end faces of the shaft drum and the shaft disc to form a cavity rotating shaft. A clutch wheel is coaxially arranged in the cavity rotating shaft and is coaxially matched and movably connected with the centers of the two inner end faces of the cavity rotating shaft. Grooves are formed in one circumference of the clutch wheel, and the ratchet wheel device is arranged on the other circumference of the clutch wheel. The outer surface of the cavity rotating shaft is provided with sliding groove holes and a clutch sliding piece, a clutch sliding sleeve can be adopted as the clutch sliding piece, and an inner clutch sliding disc or an outer clutch sliding disc can also be adopted as the clutch sliding piece. The multifunctional ratchet wheel clutch device can meet the multiple needs of the one-way clutch function, the bidirectional clutch function, the single-rotation clutch function, the direct drive function or a combination function; especially for an electric lock with a rear clutch, direct locking inside and outside a door and direct delocking and locking inside the door are achieved; and after locking, automatic unlocking can be achieved during delocking inside the door.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to a multifunctional ratchet clutch device. Background technique [0002] The clutch device is the core device of the electronic lock, and its design and installation position determines the safety, reliability and convenience of the electronic lock. The installation position of the clutch device is different, and its function and structure requirements are also different. At present, front clutch electronic locks are widely used. This type of lock has low security and cannot prevent technical or violent opening. The electronic lock with rear clutch can prevent technical or violent opening. It has the highest security and is also the development direction of electronic locks. However, due to the simple function of the clutch device used in the current electronic lock, the electronic lock used for the rear clutch will often lose sight of the other, and some functions of the lock will...
