The invention relates to a door opening and closing structure including a door plate, a transverse bar, a zipper and a pulling string. When a tension is applied on the pulling string and the tension is greater than a gravity of the transverse bar and at least a portion of the door plate, and the at least a portion of the door plate is driven by the transverse bar to move along the extension direction to form an opening. When the tension is less than the gravity of the transverse bar and the at least a portion of the door plate, the door plate is driven by the transverse bar to move along the gravity direction to reduce the opening.

A securing apparatus includes a housing, a shaft, a sprocket having teeth, a bracket having a tooth, and a torsional spring. One end of a chain is coupled with the apparatus and a rotation of the shaft wraps the chain around the shaft thereby tightening the shaft. The bracket engages the teeth of the sprocket and the torsional spring maintains said engagement. A rotation of the shaft causes the bracket tooth to engage another tooth of the sprocket teeth further wrapping the chain around the shaft thereby tightening the chain.
