Automatic door closing devices Shaw case

摘要

The present invention relates to the automatic closing device of the Shaw case door, the door having a through hole formed through the length corresponding to the height of the inner side and is inserted in the through-hole to receive a torsional stiffness when opening the door the torsion bar, characterized in that as soon mounted on the door and the main body hinge member and said hinge member connecting at the same time provided with a fixing member and the retaining member for fixing the torsion bar coupling, for fixing the support bar torsion within the through-hole.; Therefore, according to the present invention, it is possible to the poor condition of the torsion bar without having to remove the door from the body is often checked, and also there is an effect that also makes it easy to replace the bad torsion bar.
