An angle-adjustable positioning and self-closing hinge for a sealed door, comprising a hinge part, a fixing base, a fixing bar, a threaded ring and a threaded sleeve having interior threads, a connecting sleeve, a plug, and an adjustment base, the hinge part is provided with a bushing, and a leaf is fastened to an exterior of the bushing, the fixing base is provided with another bushing, the hinge part is rotatable relative to the fixing base, and the fixing bar has an outwardly extending screw portion with threads;
- and wherein, the threaded sleeve resides in the bushing, and the plug is adjustably secured in the another bushing, a first magnet, a second magnet, a first spring, a cup body, a second spring and an adjustment base are coaxially arranged in the connecting sleeve between the threaded sleeve and the plug on a long axis of the hinge, and the threaded sleeve receives the screw portion of the fixing bar to secure the hinge together, the first spring abuts between the fixing bar and a front end face of the cup body, and the first magnet is axially movable with the fixing bar, the second spring abuts the plug at one end and abuts the second magnet at the other end, the second magnet is axially movable relative to the plug, the first magnet and the second magnet are arranged in the connecting sleeve such that a magnetic force attracts each of the magnets toward one another, and the adjustment base is rotated accordingly to move the plug and the bottom of the cup body to and fro along the axis, thereby adjusting and reducing separation distance between positions of the second magnet and the plug.
An angle-adjustable positioning and self-closing hinge for a sealed door, comprising a hinge part, a fixing base, a fixing bar and a threaded sleeve, the hinge part being provided with a bushing and a leaf fastened outside the bushing, the threaded sleeve having a thin bar which constitutes the leaf, the threaded sleeve being rotatably arranged in the bushing, the leaf being rotatable relative to the fixing bar and the fixing base, and the fixing bar has an outwardly extending screw portion with threads;
- and characterized in that:
- the angle-adjustable positioning and self-closing hinge further comprises a plug and an adjustment base, the threaded sleeve is fastened inside one end of the bushing, the plug is fastened inside the other end the bushing, and the threaded sleeve and plug are spaced apart;
- the fixing bar, a threaded ring, a first magnet, a second magnet, a first spring, a cup body and a second spring are provided between the threaded sleeve and plug in the bushing, and the threaded sleeve receives the screw portion of the fixing bar to secure the hinge together, a first spring abuts between the fixing bar and the first magnet, the first magnet is movable relative to the fixing bar, the second spring abuts relative to the plug at one end and abuts the second magnet at the other end, the second magnet is movable relative to the plug, the first magnet and second magnet are magnetically attracted to each other, and the adjustment base is adjusted and rotated to correspondingly cooperate with the second magnet, the plug and the bottom of the cup body, thereby adjusting and reducing separation distance between positions of the second magnet and the plug;
- the adjustment base is adjusted and rotated to correspondingly cooperate with the second magnet, the plug and the bottom of the cup body, thereby adjusting and reducing separation distance between positions of the second magnet and the first magnet;
- wherein, the fixing bar has a protruding ring, a sliding track groove is concavely arranged on a side of an outer ring of the protruding ring, and an inner ring flange of the threaded ring is convexly arranged on a front edge of an inner circumference passing through a through hole of the threaded ring, such that the inner ring flange of the threaded ring abuts inside the sliding track groove of the protruding ring, and the sliding track groove of the protruding ring correspondingly fits the inner ring flange of the threaded ring, so as to control and position axial and circumferential separation distance of the fixing bar in sliding and moving along an axis up and down relative to the threaded sleeve, and to correspondingly cooperate with the leaf of the hinge part to predetermine a positioning angle.
