Description

Technical Field

[0001] The utility model relates to the technical field of door locks, and more specifically to a novel pet door locking device. Background Art

[0002] The door lock handle is usually in the shape of a rod, and the door lock is opened by rotating the rod-shaped handle, which is convenient, practical and widely applicable. However, sometimes, pets may accidentally rotate the door lock handle while playing or jumping, accidentally opening the door and causing unnecessary trouble. In order to prevent pets from accidentally opening the door lock, a variety of simple anti-misopening child lock devices have appeared on the market. Mechanical obstacles are set to hinder the rotation of the rotary door lock handle, or the door panel and the door frame and other peripheral planes are relatively fixed through physical connections, thereby preventing pets from rotating the door lock to open the door. However, pet door locks in the prior art mostly rely on a single locking point or a sliding fit mechanism, which prevents the door lock from being opened from the other side of the door, causing inconvenience.
