Description

Technical Field

[0001] The utility model relates to the technical field of door stopper components, in particular to a door rear stopper component. Background Art

[0002] Door suction is also commonly known as door bumper. It is a device that sucks and holds the door leaf in place after it is opened to prevent it from being closed by wind or touching the door leaf. It can increase the safety, tightness, service life and convenience of the door. It is a commonly used accessory for outdoor and indoor doors. However, it is easy to detach from the magnetic suction component, which makes the stability of the suction effect insufficient. There is no buffer when closing the door, which not only causes noise but also easily damages the suction component, reducing its service life. At the same time, the height of the ball head cannot be properly adjusted according to the size of the door gap between different door panels, which makes its use range small. Utility Model Content
