The invention discloses a device for slowing down door collision. The device comprises a box body of a mounting cavity, an abutting rod and two balancing weights; an opening communicating with the mounting cavity is formed in the lower end of the box body and is connected with a box cover; a through hole for the abutting rod to pass through is formed in the box cover; the ends, away from each other, of the two balancing weights are each connected with a spring b; two abutting walls abutting against the balancing weights on the corresponding outer sides are symmetrically arranged on the two sides of the upper end of the abutting rod; and a blocking piece is connected to the side wall of the abutting rod, and the lower end of the blocking piece is connected with a spring a sleeving the abutting rod. The device is installed at the position, away from the connecting position of a door and a door frame, of the lower end of the door, when the door suddenly rotates at a high acceleration in an accelerated mode under the strong wind, the corresponding balancing weights move one step later under the inertia effect of the balancing weights and abut against the corresponding abutting walls, and therefore the abutting rod is driven to move downwards and make contact with the ground, opposite friction force is obtained, and the moving speed of the door is reduced, so that the force of the door for impacting the door frame, a door stopper or walls is reduced, and the effect of buffering collision is achieved to a certain extent.
本发明公开了一种减缓门碰撞的装置，包括安装腔的箱体、抵触杆和两个配重块；箱体下端设有与安装腔相通的开口，开口处连接箱盖；箱盖设有抵触杆通过的通孔；两个配重块相互远离的那端分别连接一个弹簧b；抵触杆上端两侧对称设有两个与相应外侧的配重块抵触的抵触壁；抵触杆侧壁上连接有挡片，挡片下端连接套在抵触杆外的弹簧a。把本发明安装在门下端远离门与门框连接的位置，门在大风下，突然以比较大的加速度加速转动时，相应配重块在其惯性作用下晚一步移动，并与相应抵触壁抵触，如此驱动抵触杆向下移动，与地面接触，得到一个相反的摩擦力，减小门移动的速度，使得门撞击门框、门吸或墙壁的力度减小，在一定程度上起到减缓碰撞的作用。
