The invention relates to the field of door closers, and discloses a time-delay automatic door closer which comprises a door closer body, the two sides of the door closer body are sleeved with a first sealing cover and a second sealing cover in a sealed mode, a first piston and a second piston are arranged in the door closer body, and a rack is arranged between the first piston and the second piston. And a rocker arm gear for driving the rack to move is arranged on the door closer main body. Through the design that a limiting shaft is arranged at a second sub-groove, when a first piston and a second piston integrally move rightwards, hydraulic oil in a third cavity pushes a sliding plug to drive the limiting shaft to move to block the second sub-groove, and when the first piston and the second piston move leftwards, the limiting shaft slowly moves by a certain distance and then is separated from the second sub-groove, door static delay can be achieved; therefore, when the door cannot be opened by a larger angle, delayed closing of the door is always kept at 90 degrees, the delayed closing effect of the door is improved, and people can conveniently push large and heavy goods to pass through the door.
本发明涉及闭门器领域，且公开了一种延时自动闭门器，包括闭门器主体，闭门器主体的两侧密封套装有第一封盖和第二封盖，闭门器主体的内部设有第一活塞和第二活塞，第一活塞和第二活塞之间设有齿条，闭门器主体上设有驱动齿条移动的摇臂齿轮。通过第二分槽处设置限位轴，并在第一活塞、第二活塞整体右移时，第三腔室内液压油推动滑塞带动限位轴移动封堵第二分槽，且在第一活塞、第二活塞左移时，限位轴缓慢移动一段距离后与第二分槽分离的设计，使得门能够实现门静止延迟，从而便于在门无法打开更大的角度时，使得门的延迟关闭始终保持在九十度，使得门的延时关闭效果提高，便于人推动较大、笨重货物通过门。
