Abstract

The invention discloses a door lock which comprises a lock bolt, a first revolving shaft, a second revolving shaft which is coaxially arranged with the first revolving shaft, a first transmission device and a second transmission device. The first transmission device is provided with a through cavity, the first revolving shaft and the second revolving shaft are matched with the through cavity in rotating mode, the first transmission device comprises a first positioning portion, the second transmission device is coaxially arranged outside the first transmission device and comprises a second positioning portion, and the first positioning portion and the second positioning portion are matched so as to enable the first transmission device and the second transmission device to rotate relatively in a predetermined angle. Through the way, the door lock saves labor during door opening or door closing and is simple in structure and not prone to damage.

Description

technical field [0001] The invention relates to the field of locks, in particular to a door lock. Background technique [0002] Door locks are commonly used security devices in people's lives. Among existing door locks, there are door locks provided with handles inside and outside the door. For example, a door or a bedroom door etc., just need to be provided with handles inside and outside the door. However, in the prior art, when using the handle to open or lock the door, it is necessary to drive a transmission device similar to a lever structure to drive the dead bolt to move. Moreover, the short lever of the lever structure is on the handle side, and the long lever is on the deadbolt side, so it is more laborious to open or lock the door. Moreover, the lever structure is relatively complicated and easily damaged. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a door lock, which can save labor when openin...
