Document Type and Number:
WIPO Patent Application WO/2020/015600
Kind Code:
A1
Abstract:
Disclosed is a lock cylinder comprising a liner. The liner is internally provided with a driving device. An output end of the driving device is a rotating shaft. The rotating shaft is connected and fixed with a first cam and drives the rotation of the first cam. The first cam is connected to a second cam in a plane of rotation thereof in a sheathed manner, and the first cam drives the rotation of the second cam. The beneficial effect of the present invention lies in: owing to the cooperative effect of the first cam and the second cam, the requirements for an electric motor and the first cam are relatively low, such that the service life of the lock cylinder can be noticeably prolonged. By means of the design of a first groove, the liner is fixed, and rotation reversing of the liner can be also realized.
