Abstract

The invention discloses a window and door weight-bearing hinge. The window and door weight-bearing hinge is mainly provided with a hinge tube body 1, an installation tube 2 and a hinge base 3, the upper segment of the hinge tube body 1 is provided with an upper bearing seat 12, the lower segment of the hinge tube body 1 is provided with a lower bearing seat 15, one side edge of the hinge tube body1 is provided with a tube body lug 7, the upper end of the hinge tube body 1 is connected with a door and window connection pipe of the door and window through a cylinder-shaped upper outer connector8 of the upper bearing seat 12, the lower end of the hinge tube body 1 is connected with the installation tube 2 and the hinge base 3 in sequence, and a cylinder-shaped lower outer connector 5 of thehinge base 3 is connected with the door and window connection pipe of the door and window. The window and door weight-bearing hinge is reasonable in structure, simple to fabricate, large in bearing load, stout, durable, safe and reliable, installation of heavy type door and window and rapid assembling and disassembling of a operation table face or a moving slab bridge can be realized, left and right swing of the heavy type door and window, the operation table face or the moving slab bridge is prevented, the fabricating cost is low, and the window and door weight-bearing hinge has good economic and social benefits.

Description

technical field [0001] The invention relates to a connecting component of a window and door, in particular to a load-bearing hinge for a window and door.
