The invention relates to the technical field of hardware door stoppers, and discloses a self-retracting buffer door stopper which comprises a wall body. A door plate is movably mounted on one side ofthe wall body, a fixed frame is fixedly mounted at the lower end of the wall body, an attraction block is fixedly mounted in an inner cavity of the fixed frame, and a movable groove is formed in the surface of the attraction block. According to the self-retracting buffer door stopper, by additionally arranging an automatic retracting mechanism, when the door stopper is in an unused state, the doorstopper can be automatically retracted into a groove formed in the door plate according to the large gravity of a door stopper ball, and when a door is pushed to be opened and attracted to a wall, abalancing weight can compress a first corrugated pipe under the action of centrifugal force according to the magnitude of thrust, thus gas in the corrugated pipe moves into a gas conveying pipe through a ventilation cavity under the action of pressure, and a rotating sleeve drives the door stopper ball to rotate through deformation of the gas conveying pipe, so that the door stopper ball can be better attracted to the attraction block fixed to the wall, and the problem that a traditional door stopper extends out by a section, and potential safety hazards exist is solved.
本发明涉及五金门吸技术领域，且公开了一种自收回式缓冲门吸，包括墙体，所述墙体的一侧活动安装有门板，所述墙体的下端固定安装有固定框，所述固定框的内腔固定安装有吸附块，所述吸附块的表面开设有活动槽。本发明通过加设自动收回机构，使得门吸在未使用状态时，能根据门吸球重力较大，使得门吸自动收回门板开设的凹槽中，而当推开门，使门与墙壁吸附时，能根据推力的大小，使得配重块在离心力的作用下压缩第一波纹管，使得波纹管内的气体在压力的作用下通过通气腔移动至输气管中，并通过输气管变形，使得转动套带动门吸球转动，从而能更好的与固定在墙壁上的吸附块吸附，避免了传统门吸会伸出一截，存在安全隐患的问题。
