Document Type and Number:
WIPO Patent Application WO/2021/007925
Kind Code:
A1
Abstract:
Disclosed is a noiseless smart lock body with delayed springback of a one-way bolt, wherein by means of delaying the springback of a one-way latch bolt part, the effect of noiselessness is achieved. The one-way latch bolt part comprises a single latch bolt part and a linkage part. The linkage part comprises a catch part, which comprises a saw-toothed catch. The lock body comprises: a limiting part, which comprises a limiting assembly controlled by a sub-lock part; a push-pull rod connecting the limiting assembly and a limiting shifting rod; the limiting shifting rod, which is controlled by the limiting assembly or a handle part; and a guide block connected to the limiting shifting rod. The lock body further comprises a noiseless part, which comprises a noiseless driving part and a noiseless limiting part, the noiseless limiting part comprising a clamp top point. When the handle part rotates, the handle part drives the limiting shifting rod and the noiseless driving part to rotate, the limiting shifting rod drives the guide block to remove the limitation on the one-way latch bolt part, the noiseless driving part removes the limitation on the noiseless limiting part, and the noiseless limiting part moves to enable the clamp top point to be clamped into the catch, such that the one-way latch bolt part retracts into a shell part.
