Description

Electric door lock

Technical Field

The utility model relates to an electric door lock.

Background

Chinese patent CN215443552U discloses automatic flexible electric door lock of spring bolt, including lock core and first pivot, lock core and first pivot transmission are connected, and the tip of lock core and the tip of first pivot are pegged graft each other and are cooperated, and first pivot is furnished with axial reset spring, and axial reset spring cover is established in first pivot, lets first pivot push down the axial behind the lock core and remove along with the lock core in the lock shell and can move towards lock core direction and reset, and lock core and pivot all adopt metal material to make, and the cost is higher.

Disclosure of Invention

In view of the technical problems in the background art, the utility model aims to provide an electric door lock, which is capable of optimizing the material replacement of a rotating shaft structure combined with a lock cylinder and reducing the cost.

In order to solve the technical problems, the utility model adopts the following technical scheme: the electric door lock comprises a lock core and a rotating shaft, wherein the lock core is in transmission connection with the rotating shaft, the end part of the lock core is in plug-in connection with the end part of the rotating shaft, the rotating shaft is provided with an axial reset spring, the lock core is made of plastic materials, and the end part of the lock core and the end part of the rotating shaft are provided with notches.

Preferably, the recess forms a reset chamber within which the axial reset spring is disposed.

The utility model has the beneficial effects that the socket is designed at any one of the lock core end and the rotating shaft end to realize the plug-in fit, the two sockets can reduce the whole volumes of the lock core and the rotating shaft, and the rotating shaft structure is optimized to be combined with the material replacement of the lock core to effectively reduce the cost; the axial reset spring is arranged in the reset cavity, the requirement on the wire diameter of the axial reset spring is simplified, the axial reset spring can be arranged in the reset cavity, and the reset cavity can further protect the axial reset spring from being influenced by external environment. Thus, the present utility model is a substantial feature and improvement over the prior art.
