The invention discloses a door closing impact buffer. The door closing impact buffer is arranged at the edge of a door plate, and comprises a base plate, a rotary telescopic seat, a rotary telescopicrod and a constraint telescopic rod, wherein a main body of the rotary telescopic seat is a rectangular block; a telescopic hole is formed in the rectangular block; the diameter of the telescopic holeis matched with the outer diameter of the rotary telescopic rod; the rotary telescopic rod can move in the telescopic hole; a spring is arranged in the telescopic hole, and the rotary telescopic rodis kept in an extending-out state in the initial state; rotating shafts are arranged at two sides of the rotary telescopic seat; the rotating shafts are matched with rotary telescopic seat rotating holes formed in the base plate; reset springs are arranged between the rotating shafts and the rotary telescopic seat rotating holes, so that the rotary telescopic seat is kept in a horizontal positionin the initial state; a main body of the rotary telescopic rod is cylindrical; the constraint telescopic rod is a plane symmetric assembly and is symmetrically provided with two cylindrical rods; thetwo cylindrical rods are connected through a rectangular plate, and a position limiting plate is arranged in the middle of the rectangular plate. The door closing impact buffer solves the problem thatthe final speed of a door body in the moving process cannot be restrained by an existing door body fixer.
本发明公开了一种关门撞击缓冲器，安装于门板边缘，包括基板、旋转伸缩座、旋转伸缩杆和约束伸缩杆；旋转伸缩座主体为矩形块，矩形块内设有伸缩孔，伸缩孔的直径与旋转伸缩杆的外径相配合，旋转伸缩杆可在伸缩孔内运动，伸缩孔中设有弹簧，保持旋转伸缩杆在初始状态处于伸出状态；旋转伸缩座两侧有旋转轴，旋转轴与基板上的旋转伸缩座旋转孔相配合，旋转轴与基板上的旋转伸缩座旋转孔之间设有恢复弹簧，保持旋转伸缩座初始状态处于水平位置；旋转伸缩杆主体为圆柱形；约束伸缩杆为面对称组件，对称设置有两根圆柱杆，两根圆柱杆之间通过矩形板连接，矩形板中间设有限位板；解决了现有门体固定器不能实现对门体运动过程末速度的约束问题。
