The invention discloses a door stopper for a door to be easily pulled. The door stopper comprises a movable block and a fixed box, wherein the movable block is fixed to a door sheet, and the fixed block is fixed to a wall surface. An insertion rod is fixed to the side wall of the movable block. A clamping groove is formed in the side wall of the insertion rod. A penetration hole is formed in the side wall of the fixed box in a through manner. The insertion rod penetrates through the insertion hole and extends into the fixed block. A rotary barrel is rotationally connected with the side wall ofthe fixed box. A driven gear is fixed to the side wall of the rotary barrel. A limiting groove is formed in the side wall of the driven gear in a through manner. Multiple limiting blocks are evenly distributed inside the limiting groove. The door stopper for the door to be easily pulled has the advantages that when the door needs to be stopped, the door sheet is pushed again to enable a piezoelectric ceramic block to be pressed again, high voltage is applied to electrorheological fluid again, then a rotary shaft is enabled to rotate again, the limiting blocks rotate again to change the positions so as to get away from the clamping groove and not limit the insertion rod any longer, the insertion rod can be easily moved out of a fixing block, and the door sheet can be easily closed withoutbeing applied with high tensile force.
本发明公开了一种易拉门吸，包括固定于门板上的移动块好和固定于墙面的固定盒，所述移动块的侧壁固定有插杆，所述插杆的侧壁开设有卡槽，所述固定盒的侧壁贯穿开设有插孔，所述插杆贯穿插孔延伸至固定盒内部，所述固定盒的侧壁转动连接有转筒，所述转筒的侧壁固定有从动齿轮，所述从动齿轮的侧壁贯穿开设有限位槽，所述限位槽内部均布有多个限位块。优点在于：本发明中，在需要关门时，再次推动门板使得压电陶瓷块再次受压，再次对电流变液施加高电压，从而使得转轴再次转动，进而使得限位块再次转动转换位置，从而脱离卡槽不再对插杆限位，使得插杆能够轻松地移出固定块，进而使得门板能够轻易的关闭，不需要施加较强的拉力。
