The invention discloses a door closing protection device capable of effectively preventing wind from bringing a door to impact a door frame. The door closing protection device comprises two mounting plates and two mounting pipes, wherein the two mounting plates and the two mounting pipes are fixedly connected to a wall; a guide rod is arranged between the two mounting plates and penetrates throughthe two mounting pipes; the guide rod comprises two strip-shaped magnets; and a connecting rod is fixedly connected between the two strip-shaped magnets. By means of the door closing protection device, the phenomenon that the door is brought by strong wind and rapidly impacts the door frame when the door closing speed is too high can be effectively avoided, then the door frame is well protected,and the service life of the door frame is prolonged; and when the door is opened, the door can pull a first sliding piston to reset by means of the suction effect between the door and a suction cup, hydraulic oil in a bottom cover is sucked back into a sealing cavity through the negative pressure effect, a second sliding piston is driven to reset, and therefore the whole device can automatically reset.
本发明公开了一种有效预防风带门撞击门框的闭门防护装置，包括固定连接在墙壁上的两个安装板和两个安装管，两个所述安装板之间设有导向杆，所述导向杆从两个安装管内穿过，所述导向杆包括两个条形磁铁，两个所述条形磁铁之间固定连接有连接杆。本发明能够有效的避免强风带门以及关门速度过快时存在的门快速撞击门框的现象发生，进而对门框形成良好的防护，延长门框的使用寿命，在开门时，门会借助与吸盘之间的吸力作用，拉动第一滑动活塞复位，通过负压作用将底罩内的液压油吸回密封腔内，并带动第二滑动活塞复位，从而使得整个装置自动复位。
