Abstract

See full text

An auto-closing device has a base, a cylinder, a slider, a spring and an adjusting device. The adjusting device is connected to an end of the spring opposite to the slider and has an adjusting frame and an adjusting bolt. The adjusting frame has a first end connected securely to the spring and a second end provided with a threaded hole. The adjusting bolt is mounted rotatably on the base and is screwed into the threaded hole in the adjusting frame. Accordingly, when the adjusting bolt is rotated, the adjusting frame is moved relative to the body so that the pulling force provided by the spring is adjusted to fit with different door panels with different weights.
