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.

Disclosed is a refrigerator with a storage space. The refrigerator includes a main body including a storage space, a door configured to open and close the storage space, and a hinge provided under the door and configured to rotatably couple the door to the main body. The hinge includes a linear member accommodator configured to accommodate therein a linear member drawn out from the door, and a cut-out portion hollowed and configured to extend along a hinge axial direction to allow the linear member accommodator to communicate with an outside at one side.

Systems and methods for swiveling a panel in relation to a panel frame are described. An exemplar panel swivel system includes a swivel support member, a housing subassembly, and a shaft. The swivel support member includes a base portion that has a first terminating end, a second terminating end, and has defined therein a shaft receiving aperture. The swivel support member further includes a raised surface extending from the first terminating end of the base portion and is designed to contact a top support structure and a securing edge extending from the second terminating end of that base portion, which is designed to contact a side support structure. The housing subassembly extends an elevated distance above the base portion. A central aperture defined in the housing subassembly aligned with the shaft receiving aperture. The shaft extends a shaft length and at least some of the shaft passes through the central aperture and the shaft receiving aperture. The shaft terminates at a panel fitting end that is designed to engage with a panel.

A roller with a plastic injection tube to coat the steel shaft wherein the plastic coated shaft eliminates the metal-to-metal contact that creates the noise. Further disclosed is an improved roller wheel having a tire made of material selected from the group consisting of urethane and urethane (PER) on which the roller will roll within a garage door track to significantly reduce the noise of the roller as it rolls inside the garage door tracks as the garage door is raised and lowered. The roller shaft has the treads extending to a distal end of the roller shaft where a plastic washer and a closing cover nut with interior threads are threaded onto the distal end of the roller shaft. The closing cover nut with interior threads is selected from an acorn nut with a nylon insert and a hex lock nut with a nylon insert.

The present disclosure provides a hinge, such as for housings for devices, such as a split-core current transformer. The housings can include hinges and housing parts to be rotatably coupled together at such hinges that can be injection molded. A hinge of a housing can include a first knuckle and a second knuckle, which can be integrally formed with or coupled to a first housing part and each are configured to receive an end of a hinge pin. One of the knuckles includes a knuckle slot to provide radial access for a cut-away portion of a hinge pin to pass through. At assembly of the first housing part to a second housing part, a first hinge pin end is to be disposed within an opening of the first knuckle and a second hinge pin end is to be disposed within the second knuckle after passage of the key portion through the knuckle slot of the second knuckle.

A hinge assembly includes a first hinge element having a hinge pin with upper and lower portions and an engagement portion outwardly extending from the hinge pin. The engagement portion of the first hinge element includes a lower surface having an upwardly angled portion and an abutment surface. A second hinge element includes a body portion surrounding a hollow interior portion and further includes a contoured upper rim having a downwardly angled portion and an abutment surface. The lower portion of the hinge pin of the first hinge element is slideably received in the hollow interior portion of the second hinge element. The first hinge element rotates between a first position, wherein the abutment surface of the first hinge element abuts the abutment surface of the second hinge element, and a second position, wherein the abutment surfaces of the first and second hinge elements are spaced-apart from one another.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body. A guide block is provided on the door, a rotation shaft is provided on the hinge body, and rotation shaft grooves are provided on the guide block. With the structure of the hinge body, the gravity of the door and the friction force may be shared onto the first and second plate bodies of the hinge body, thereby reducing abrasion and prolonging the service life of the door of the refrigerator.
