AI Technical Summary
Technical Problem
Traditional front doors generate a lot of noise when closing and may damage internal components due to vibration.
Method used
The entrance door locking structure is designed with a silent magnetic lock, a buffer assembly, and a sound-absorbing cavity. The silent magnetic lock keeps the bolt in the lock box after the door is opened and automatically locks after the door is closed. The buffer assembly absorbs noise through elastic sheets and sealing plates, and the sound-absorbing cavity limits the propagation of sound.

Abstract
This utility model provides a locking structure for an entrance door, including a door frame, a door panel, and a door lock. The door frame is installed inside a wall, the door panel is hinged to one side of the door frame, and the door lock is installed inside the door panel. The door lock is a silent magnetic lock, which includes a lock box, an inner handle, and an outer handle. The lock box is installed inside the door panel, the inner handle is installed on the inner side of the door panel, and the outer side of the inner handle's pivot is rotatably connected to the door panel, with one end of the pivot fixedly connected to the lock box. The outer handle is installed on the outer side of the door panel. This utility model's locking structure for an entrance door incorporates a buffer component and a sound-absorbing cavity, which reduces noise generated when closing the door and further reduces noise by limiting sound propagation, making the door closing almost noiseless and solving the problem of excessive noise when closing the door, thus achieving the goal of silent door closing.
