ANGLE-ADJUSTABLE POSITIONING AND SELF-CLOSING HINGE FOR HIGHLY SEALED DOOR
Document Type and Number:
WIPO Patent Application WO/2017/054728
Kind Code:
A1
Abstract:
Provided is an angle-adjustable positioning and self-closing hinge for a highly sealed door, comprising a hinge leaf (10), a fixing base (20), a fixing bar (30), a screw lock insert (40), a spiral ring (43), a plug head (60), and an adjustment socket (70); the hinge leaf (10) is provided with a bushing (11) and a blade (12); the fixing base (20) is provided with a bushing (21); the fixing bar (30) has a threaded rod (31); a screw lock insert (40) is fastened inside the bushing (11), the plug head (60) is fastened inside the bushing (21), and the screw lock insert (40) and plug head (60) are spaced apart; between the screw lock insert (40) and plug head (60) in the two bushings are disposed the fixing bar (30), the two magnets, two springs, and the adjustment base (70); the threaded rod (31) of the fixing bar (30) is screwed to the screw lock insert (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 head (60), thereby adjusting and reducing the separation distance between the positions of the second magnet and the plug head (60). The adjustment base (70) is adjusted and rotated to fit the second magnet and the bottom of the cup body (61) and plug head (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 leaf (10), such that the hinge leaf (10) may self-position at the start point positions of any preset angle between predetermined positioning angles; further, the hinge leaf (10) at a positioning angle between the predetermined positioning angles may self-position below a position start point so that the blade (12) of the hinge leaf (10) closes itself.
