[0040] see Figure 1-Figure 9 , the concealed hinge that opens inwards and inverts, including the window frame connecting arm 1 set on the top mounting rail of the window frame 71 and the window door connecting arm 2 set on the top mounting rail 61 of the window door 72, which are connected to each other through the hinge structure, The hidden hinge also includes a positioning arm 3 for being installed on the side mounting rail 62 of the window door 72. The positioning arm 3 is provided with a bolt assembly, and the hinge structure includes a locking hinge 43, and the locking hinge 43 is provided with a lock Buckle components.

[0041] When the locking hinge 43 moves to be in the same vertical plane with the positioning arm 3, the snap assembly is buckled in the deadbolt assembly. At this moment, the window frame 71 and the window door 72 are inwardly opened, as Figure 5-Figure 7 As shown, the side mounting rails 62 bear the force of gravity to avoid deformation.

Abstract

An inward tilt-turn hidden type hinge comprises a window frame connecting arm arranged on a window frame top mounting rail and a window door connecting arm arranged on a window door top mounting rail, wherein the window frame connecting arm and the window door connecting arm are in transmission connection through a hinge structure; the hidden type hinge further comprises a positioning arm mounted on a window door side mounting rail, a spring bolt assembly is arranged on the positioning arm, the hinge structure comprises a locking hinge, the locking hinge is provided with a lock catch assembly, when the locking hinge moves to the position located on the same vertical face with the positioning arm, the lock catch assembly is buckled in the spring bolt assembly, and when the locking hinge moves to the position in the different vertical faces with the positioning arm, the lock catch assembly is separated from the spring bolt assembly. The hinge is applied to a window, the lock catch assembly of the hinge can be buckled in the spring bolt assembly, and stress of the hinge structure is more uniform.

Description

technical field [0001] The invention belongs to the technical field of door and window connecting devices, and in particular relates to a concealed hinge that opens inward and inverts. Background technique [0002] Chinese Patent Document No. CN205330326U discloses a built-in invisible friction hinge, including a window frame connection structure and a window and door connection structure, the window frame connection structure is connected to the window and door connection structure through a hinge structure to form a retractable sliding door and window structure; The window frame connection structure includes a window frame hinge plate and at least two rigid clamping positions arranged on the window frame hinge plate, at least two external movable connectors and an internal movable connector; the rigid clamping position and the window frame hinge plate are It is integrally formed or fixedly connected to the side of the hinge plate of the window frame to form a fixed clampin...
