Problems solved by technology

Most of these window hinges are exposed hinges, which in some cases will affect the beauty of the windows. The hidden hinges that appear on the market are generally completed by connecting several steel plates with each other, and the hidden effect is not good. And the load-bearing capacity is weak, the steering flexibility is low, and it cannot be used for large windows

Abstract

The invention discloses a hidden type lower hinge. The hidden type lower hinge comprises a hinge base mounted in a lower window frame, a rotating shaft mounted in a lower window sash, and a rotating connecting part mounted between the hinge base and the rotating shaft, wherein the hinge base comprises a first mounting plate and a second mounting plate; a concave grove is formed between the upper surface of the first mounting plate and the bottom surface of the second mounting plate; a group of communicating U-shaped grooves and through holes is formed above the hinge base; the rotating connecting part comprises a first connecting part and a second connecting part; a fixing rod is arranged above the first connecting part; an arc-shaped limiting groove is formed in one side close to the fixing rod; a limiting rod is arranged below the other side of the fixing rod; a sliding rod is arranged at the bottom part of the second connecting part and slides in parallel along the communicating U-shaped grooves; the sliding rod is in match with the arc-shaped limiting groove to limit the first connecting part to rotate in one direction; a shaft rod is arranged above the other side of the sliding rod through the second connecting rod; the rotating shaft rotates along the shaft rod. The hidden type lower hinge is stable in structure, high in bearing performance, convenient and quick to mount, and flexible to rotate.

Description

technical field [0001] The invention relates to the field of door and window hinges, in particular to a hidden lower hinge. Background technique [0002] At present, the hinge structure used is very simple. Two hinges are respectively installed on the window frame and the window sash, and the two hinges are connected through the rotating shaft to realize the opening and closing of the hinge. Some are more complicated, and two brackets are used. One support has a slide bar, and the other support has a groove, and the slide bar slides in the groove to achieve the purpose of closing. Most of these window hinges are exposed hinges, which in some cases will affect the beauty of the windows. The hidden hinges that appear on the market are generally completed by connecting several steel plates with each other, and the hidden effect is not good. Moreover, the load-bearing capacity is weak, the steering flexibility is low, and it cannot be used for large windows. Contents of the i...
