Description

TECHNICAL FIELD

[0001] The present application relates to the field of building hardware, in particular to a heavy adjustable hinge. BACKGROUND

[0002] Aluminum alloy casement windows are widely used in civil buildings. As the main component of casement windows, hinges are responsible for all the load bearing and ensuring the smooth opening of the door leaf. However, the existing aluminum alloy casement windows generally have the problem of corner drop, and the corner drop problem becomes more serious with the increase of the weight and size of the door leaf. Currently, adjustable hinges are commonly used on the market to improve the corner drop problem of the door leaf, but the adjustment structure of these adjustable hinges is arranged at the pivot position. This structure is complex and unreliable, and the adjustment structure is easy to loosen during repeated opening and use, which causes the door leaf to drop and affects normal closing and use. Even worse, the hinge may damage the door leaf and fall off, so a simple and reliable adjustable hinge needs to be designed. SUMMARY
