In an assembled state of a hinge, the hinge is configured to be capable of adjusting a rotational position when holding a door or the like. The hinge includes a first member (1) and a second member (2) which are rotatable relative to each other. A first cam (11) is provided on the first member (1), a second cam (12) is provided on the second member (2) so as to be non-rotatable and movable in an axial direction thereof, and the second cam (12) is biased to the first cam (11) by biasing means (14) in the axial direction. The first cam (11) and the second cam (12) are configured to hold the second cam (12) in a predetermined rotational position relative to the first cam (11) by biasing force of the biasing means (14). In the assembled state of the hinge, it is possible to adjust the rotational position of the first cam (11) relative to the first member (1). The holding force of the first member (1) to the first cam (11) is larger than the holding force of the first cam (11) to the second cam (12) in a circumferential direction thereof.

A pivot hinge includes a spring housing with a central tube, a spring assembly, an upper mounting plate, and a lower mounting plate. The bottom end includes a knurled outer surface. A stop cam is positioned about the knurled outer surface and has an inner surface that conform to the knurled outer surface so that it may be positioned in a plurality of rotatable positions relative to the central tube. The stop cam also has an exterior surface which includes a detent. The different rotational positions of the stop cam upon the knurled outer surface changes the relative position of the detent in relationship to the central tube. A cam follower assembly is coupled to the lower mounting plate and has a cam follower plate with a cam follower that rides upon the stop cam and engages the detent recess to hold the door in an open position.

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.

A container includes a housing, a casing pivotally connected to the housing with a pivot axle, one or more magnetic members engaged in the housing, and one or more magnetic elements engaged in the casing and disposed close to the magnetic member for acting with the magnetic member and for anchoring the casing to the housing at any selected angular position. The housing includes a slot formed in a seat, and the magnetic member is engaged in the slot of the seat. The housing includes a passage formed in the seat, and the pivot axle is engaged in the passage of the seat. The magnetic member includes an aperture formed in the magnetic member for receiving and engaging with the pivot axle.

A positionable hidden hydraulic hinge configured for installation of a door is provided. The positionable hidden hydraulic hinge includes a non-movable device body configured to be connectable with a door frame, a rotatable device body configured to be connectable with a door leaf, and a hinge configured to connect the non-movable device body and the rotatable device body. The rotatable device body includes a bearing guiding base having a guiding groove and a hydraulic chamber body. The positionable hidden hydraulic hinge also includes a linkage assembly configured to penetrate throughout the hinge. Two ends of the linkage assembly are configured to pivotably connect with the non-movable device body and an internal mechanism of the rotatable device body, respectively. A first end of the bearing guiding base is fixedly connected with the hinge, and a second end of the bearing guiding base is connected with the hydraulic chamber body.

The present disclosure provides a structure configured to preset an automatic positioning duration to enable hinge blades to be automatically closed, the structure two hinge blades, a threaded sleeve, a fixed rod, a first spring, a electromagnet suction disk, a DC power supply electromagnet, a DC power supply timing controller, a remote control, a plug, and an adjusting base. The two hinge blades are configured to rotate relative to each other, each of the two hinge blades comprises a shaft sleeve and a blade fixed on an outer side of the shaft sleeve, the fixed rod comprises a threaded rod, the threaded sleeve comprises a transmission rod fixed in the shaft sleeve of the two hinge blades, the plug is fixedly disposed in the shaft sleeve of the two hinge blades, the threaded sleeve is separated from the plug, and the fixed rod, the first spring, the electromagnet suction disk, the power supply electromagnet, a bearing, and the adjusting base are disposed between the threaded sleeve and the plug disposed in the shaft sleeve of the two hinge blades. When the hinge blades reach the automatic positioning time preset by the timing controller, so that the hinge blades synchronously cooperates with the demagnetization time point preset by the timing controller. At the same time, the elastic force energy storage of the first spring changes and releases. An application of the present disclosure is wide, and has good industrial applicability.

A multi-link door hinge is proposed. The multi-link door hinge includes: a main body frame provided in a main body of an apparatus having a door; a door frame provided on the door; a body frame rotatably connected to one side portion of the main body frame; an inner link and an outer link rotatably connecting the door frame to the body frame; a leaf spring link rotatably connecting the main body frame to the outer link; an upper cam coupled to a portion connecting the body frame to the inner link in a co-rotatable manner, provided between first and second side portions of a sidewall of the inner link, and securely coupled to the body frame; an upper elastic member having a first side portion provided inside the inner link and a second side portion rollably coupled to the upper cam and elastically supporting the door frame.

A multi-link hinge is proposed. The multi-link hinge is configured to facilitate closing and opening of a door, is capable of sufficiently securing a maximum opening angle of the door while decreasing a gap between the door and a main body, and is also capable of providing convenience to a user when the user opens and closes the door.

A flip hinge for a motor vehicle includes an inner strap affixed to a body of the motor vehicle, an outer strap separate from the inner strap and affixed to a removable panel of the motor vehicle, and an intermediate link extending from the inner strap to the outer strap. The intermediate link is rotatably attached to the inner strap at a first link end by a spring-loaded pivot. The intermediate link is rotatably attached to the outer strap at a second link end by an outer strap pivot. The intermediate link is movable between at least a first position and a second position. The spring-loaded pivot biases the intermediate link towards the second position whenever the intermediate link is not in the first position, and the outer strap is separable from the intermediate link only when the intermediate link is in the first position.

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.
