Abstract

Provided is an angle-adjustable positioning and self-closing hinge for a highly sealed door, comprising a hinge part (10), a fixing base (20), a fixing bar (30), a threaded sleeve (40), a threaded ring (43), a plug (60), and an adjustment socket (70); the hinge part (10) is provided with a bushing (11) and a leaf (12); the fixing base (20) is provided with a bushing (21); the fixing bar (30) has a screw (31); a threaded sleeve (40) is fastened inside the bushing (11), the plug (60) is fastened inside the bushing (21), and the threaded sleeve (40) and plug (60) are spaced apart; between the threaded sleeve (40) and plug (60) in the two bushings are disposed the fixing bar (30), the two magnets, two springs, and the adjustment base (70); the screw (31) of the fixing bar (30) is screwed to the threaded sleeve (40); a first spring (91) abuts between the fixing bar (30) and the front outer ring edge and washer (85) of a cup body (61); the first magnet (81) and second magnet (82) are magnetically attracted to each other. The adjustment base (70) is adjusted and rotated to correspondingly fit the second magnet (82) and the bottom of the cup body (61) and plug (60), thereby adjusting and reducing the separation distance between the positions of the second magnet and the plug (60). The adjustment base (70) is adjusted and rotated to fit the second magnet and the bottom of the cup body (61) and plug (60), thereby adjusting and reducing the separation distance between the positions of the second magnet (82) and the first magnet (81). The adjustment base (70) correspondingly fits and adjusts the predetermined positioning angle of the hinge part (10), such that the hinge part (10) may self-position at the start point positions of any preset angle between predetermined positioning angles; further, the hinge part (10) at a positioning angle between the predetermined positioning angles may self-position below a position start point such that the leaf (12) of the hinge part (10) closes itself.
