Lock clutch device and lock

Abstract

The invention relates to the technical field of locksets, and discloses a lockset clutch device and a lockset. The lockset clutch device comprises a handle rotating sleeve, a rotating block, an inserting pin and a clutch device body, and the inserting pin has an unlocking state and a locking state; the end, facing the inserting pin, of the clutch device body is provided with a plugging and unplugging station, a limiting face and a pulling-out assembly, the plugging and unplugging station is used for pushing the inserting pin to be locked from an unlocked state, the inserting pin is kept in thelocked state through the limiting face, and through the pulling-out assembly, when the inserting pin is located at the plugging and unplugging station in the locked state, the inserting pin is pulledout to be in the unlocked state from the locked state. In the lockset clutch device, by arranging the limiting face and the pulling-out assembly, locking and unlocking are switched between the handlerotating sleeve and the rotating block, when the handle rotating sleeve rotates, the inserting pin slides along the limiting face, blocking is avoided when the inserting pin rotates, and accordinglythe structural stability of the lockset clutch device is improved.

Description

Technical field [0001] The invention relates to the field of locks, in particular to a lock clutch and lock. Background technique [0002] In addition to unlocking with fingerprints and passwords, the smart door lock is also equipped with a key to unlock. Key unlocking mainly has two ways to open a hole on the front and bottom. Front unlocking is relatively simple and convenient, directly controlling the lock cylinder, but the design affects the appearance of the lock surface. The bottom unlocking structure is more complicated than the front unlocking structure. The general design is that after the door handle and the movable adapter block are connected by a clutch control pin, the handle is rotated to achieve the purpose of unlocking. [0003] In the prior art, the plug-in state of the clutch control pin is usually used to realize the connection between the door handle and the movable adapter block. A sliding block is provided on the plug and a groove-shaped arc guide rail is pro...

Problems solved by technology

[0003] In the prior art, the clutch is usually used to control the plug-in and pull-out state of the bolt to realize the connection between the door handle and the movable adapter block. A slider is set on the bolt and a groove-shaped arc guide rail is set on the clutch, and the slider is located in the arc guide rail. Cooperate with the arc guide rail, and control the insertion and withdrawal state of the bolt through the clutch movement, but when the door handle and the movable adapter block are rotated, the slider moves back and forth in the arc guide rail, which is prone to jamming
