The invention discloses a simple spring door device capable of being automatically closed. The simple spring door device comprises a door pillar, a torsion spring, a wearable pad, a door bracket as well as a positioning ring plate and a supporting plate which are welded and fixed on a door frame, wherein a short tube is welded in a supporting plate hole to form the door bracket for supporting the door pillar. During installation, the door pillar penetrates through the positioning ring plate and then is dropped on the supporting plate which is padded with the wearable pad. The door pillar is a hollow steel tube, and the torsion spring is arranged in the steel tube. A fixing ring at the upper end of the spring is fixed with the door pillar through a pin. The length of the pins is a bit greater than the diameter of the door pillar tube. Therefore, after the installation, the door pillar can be prevented from being drawn out of the positioning ring. A fixing ring at the lower end of the torsion spring is inserted into a narrow slot in the upper part of a spring regulator which penetrates in from the lower surface of the door bracket. After the resilience force degree of the door is regulated to the best state by rotating the regulator, the door and the door bracket are fixed through the pin. The simple spring door device is relatively simple in structure and manufacturing, and parts such as the torsion spring are completely sealed in the door pillar tube, so that the corrosion due to exposure to sun and rain can be effectively prevented. Meanwhile, the effect of automatically closing the door after entering the door is reliably realized.
