The invention discloses a steel door internal buffering device which comprises a supporting base, a hinge base, hinge blocks and a buffering rod, wherein the hinge base is installed on the outer wall of the supporting base, two sets of supporting blocks are installed on the outer wall of the supporting base, and the supporting blocks are located on one side of the hinge base. The angle of a steel door is fixed by installing the hinge blocks and the hinge base, after a door leaf rotates to the top part of the buffering rod, the hinge blocks move when pressure is applied to the top parts of the hinge block s during rotation of the door leaf, the hinge blocks move to drive a first round hole to move, after the first round hole is aligned with a second round hole, a stop pin is inserted into the first round hole and the second round hole, and therefore the purpose of locking the opening angle of the steel door is achieved.

    本发明公开了一种钢质门内部缓冲装置,包括支撑座、铰链座、铰链块和缓冲杆,所述支撑座的外壁安装有铰链座,所述支撑座的外壁安装有两组支撑块,且支撑块的位于铰链座的一侧。本发明通过安装有铰链块和铰链座来固定钢质门的角度,门页转动至缓冲杆的顶部后,门页转动时对铰链块的顶部施加压力时铰链块移动,铰链块移动带动一号圆孔移动,一号圆孔与二号圆孔对齐后,止动销插入到一号圆孔与二号圆孔的内部,从而实现钢质门的开启角度锁定的目的。
