Technical Field

The invention relates to the technical field of door stoppers, in particular to a door stopper with a buffering function.

Background

The door stopper is also commonly called as a door stopper, and is also a device for sucking and positioning the door leaf after the door leaf is opened so as to prevent the door leaf from being closed by wind or touching the door leaf. However, the door stopper in the existing market is only installed on the wall and the door plate respectively through a simple group of magnets, and when the door is closed, the door plate is prevented from swinging through magnetic attraction. However, when the door panel is pushed by a strong force or wind, the door panel collides with the door stopper on the wall, and the door stopper is damaged due to severe collision and affects subsequent normal use.

To this end, we propose a door stopper with a buffering function to solve the above problems.
