Problems solved by technology

In essence, this solution uses two four-link structures to make the opening and closing angle greater than 90 degrees, but its moving distance is large, which increases the moment arm between the door and the door frame after the door is opened, reducing the load-bearing capacity; At the same time, the seven-axis structure is applied, the structure and process are complex, the friction of opening is large and the firmness is reduced

Abstract

The invention relates to a loose leaf, providing a loose leaf with large load bearing capacity and opening angle not less than 180 deg., comprising: a base to be installed on a door or window frame; an extension arm arranged on the base and able to move on the base in the direction vertical to the rotating shaft of a door leaf; an adhesion arm with one end hinged through f shaft with one end of the extension arm; a first link rod hinged through c shaft with the extension arm; and a second link rod hinged through a and d shafts with the first link rod and the adhesion arm, respectively, where the extension arm, the adhesion arm, and the first and second link rods compose a four-link rod mechanism, and one end of the first link rod is hinged with the base. And it is especially applied to fire doors.

Description

Technical field [0001] The invention relates to a hinge with multiple pins for doors, windows or wings, in particular to a hinge with high load-bearing capacity and large opening and closing angles. Background technique [0002] With the improvement of the decorative performance, anti-theft performance and fire resistance of doors and windows, the weight of doors and windows has increased significantly, and at the same time, the requirements for their opening and closing angles are increasing. For example, the opening angle of fire doors is required to reach 175. At the same time, the door is required to be beautiful and obviously does not occupy space. In this way, the traditional single-axis hinge cannot meet the current requirements due to its poor load-bearing capacity and structural exposure. [0003] In response to these problems, the industry has been improving, and three-link and four-link hinges have emerged. For example, a concealed hinge that is easy to install, disclo...
