The invention discloses a hidden door stopper. The hidden door stopper includes a cylinder body and a stopping block; the inside of the cylinder body is successively provided with a first round hole and a second round hole from bottom to top; the diameter of the second round hole is slightly smaller than the diameter of the first round hole; the upper part of the stopping block is a 1/4 sphere, the lower part of the stopping block is a cylinder, and the diameter of the cylinder matches the diameter of the second round hole; the stopping block is in part rotatable connection with the second round hole of the cylinder; the straight ridge line of the 1/4 sphere of the stopping block coincides with the rotating axis; and the lower part of the side of the stopping block far away from the 1/4 sphere is provided with a stopping stud. The hidden door stopper is simple and convenient to operate, reliable in stopping, can be hidden under the ground when not in use, cannot cause visual impact onthe surrounding environment, and cannot affect walking of people.
本发明公开了一种隐藏式门阻挡器，包括圆筒体、阻挡块；圆筒体内部从下至上依次设有第一圆孔、第二圆孔，第二圆孔直径略小于第一圆孔直径，阻挡块上部呈1/4球体，阻挡块下部呈圆柱体，且圆柱体的直径与第二圆孔的直径相配适，阻挡块与圆筒体的第二圆孔部分转动连接，阻挡块的1/4球体的直棱线与转动轴重合，阻挡块的远离1/4球体侧的下部设有阻挡螺柱。本发明操作简单方便，阻挡可靠，在不需用时可以隐藏在地表下，不会对周围环境造成视觉影响，不会影响人的行走。
