Hinge for door of wall box, has two complementary hollow windings, and solid shaft, where one of windings extends over angular extent exceeding specific degrees so that windings extend angularly within itself

摘要

The hinge has two complementary hollow windings (10, 20), and a solid shaft (11) that is introduced into a holding channel (21). The solid shaft is formed integrally in one of the two hollow windings, where the shaft is arranged at an end of one winding. The holding channel is integrally formed on another winding. The holding channel is positioned such that the shaft remains in the holding channel. One of the windings extends over an angular extent exceeding 360 degrees so that the windings extend angularly within itself.
