A pivot hinge includes a spring housing with a central tube, a spring assembly, an upper mounting plate, and a lower mounting plate. A pivot pin is positioned within the central tube and is coupled to a torsion spring. A top end of the pivot pin is received within a central channel of a spring bushing. The spring bushing has a cylindrical main portion and a undulating ridge forming three radially positioned high areas or tongues and three radially positioned low areas, troughs or grooves. The grooves are configured to receive or mesh with interior steps in the central tube to prevent relative rotation between the spring bushing and the central tube Each tongue also includes a spring mounting recess therein. The top end of the cylindrical main portion extends through and is journalled within the top opening of the central tube.

An object is to provide a hinge which can attach a supporting part for supporting rotatably a holder part easily to the holder part holding the door. A hinge comprises a holder part for holding a door (front-side body receiving a left-and-right adjustment segment and back-side body), a supporting part for supporting rotatably the holder part (resin bush inserted in a rotation shaft), and a connection part (resin catcher) for connecting the holder part to the supporting part, and the resin catcher comprises an attachment part (recesses) for attaching to the holder part and a pawl for gripping elastically the supporting part.

A hinge module includes a plurality of discs, a plurality of friction plates and a restraining member. The discs are eccentrically connected to each other. Each of the friction plates has a circular hole, each of the friction plates is rotatably disposed on one of the discs through the circular hole, and the friction plates contact each other. The restraining member is disposed on the friction plates.

The present invention provides a refrigerator, comprising a refrigerator body and a door body. A hinge body is disposed on the refrigerator body. A first hinge shaft and a second hinge shaft are disposed on the hinge body. A first guide groove and a second guide groove are formed in the door body. The first hinge shaft is located in the first guide groove and the second hinge shaft is located in the second guide groove. During opening of the door body, the first guide groove moves relative to the first hinge shaft and the second guide groove moves relative to the second hinge shaft, the first hinge shaft applies an acting force to the first guide groove to drive the end, away from the first guide groove, of the second guide groove to approach the second hinge shaft, so that the door body is displaced in a horizontal direction.

A pivot assembly includes a fixing base, a pivot portion, a center shaft, a compression spring and two hollow abrasion proof pieces. The fixing base is equipped with an isolating board defining a fixing hole. The pivot portion defines a pivoting hole in alignment with the fixing hole. The center shaft is inserted into the fixing hole and the pivoting hole. The compression spring is mounted around the center shaft. The two hollow abrasion proof pieces are sleeved around the center shaft. The two abrasion proof pieces are located between the isolating board and the pivot portion. The compression spring is located between the two abrasion proof pieces. An electronic device includes the pivot assembly.
