Provided is an angle-adjustable positioning and self-closing hinge for a highly sealed door, comprising a hinge part, a fixing base, a fixing bar, a threaded sleeve, a threaded ring, a plug, and an adjustment socket; the hinge part is provided with a bushing and a leaf; the fixing base is provided with a bushing; the fixing bar has a screw; a threaded sleeve is fastened inside the bushing, the plug is fastened inside the bushing, and the threaded sleeve and plug are spaced apart; between the threaded sleeve and plug in the two bushings are disposed the fixing bar, the two magnets, two springs, and the adjustment base; the screw of the fixing bar is screwed to the threaded sleeve.

An electronic device and a hinge assembly thereof are provided. The hinge assembly has a first fixing block, a second fixing block, a first linking rod and a second linking rod. The first fixing block has a first end and a second end. The second fixing block has a third end and a fourth end. The first linking rod has a fifth end slidably and rotatably connected to the second end and a sixth end rotatably connected to the fourth end. The second linking rod has a seventh end slidably and rotatably connected to the fourth end and an eighth end rotatably connected to the second end. The sixth end has a groove portion and a first inclined surface, and the eighth end has a second inclined surface contacting the first inclined surface.

A hinge arrangement for detachably connecting construction elements that are to be pivotably connected to each other is provided with an axial pin with a first end provided with a collar wider than the pin body. A first hinge part with a first bushing is to be connected to a first construction component. A second hinge part with a second bushing is to be connected to a second construction component. The first and second hinge parts are connected pivotably to each other by the axial pin extending through the first and second bushings. The axial pin has a recess. The first hinge part has a fixation element extending into the first bushing and slidable transverse to a longitudinal extension of the axial pin. The fixation element has a projection projecting in a connected state of the first and second construction elements into the recess of the axial pin.

A hinge includes a first end plate, a second end plate and at least one inner plate positioned between the first end plate and the second end plate. The first end plate is connected to the at least one inner plate by a first pin that extends through the first end plate and the at least one inner plate. The second end plate is connected to the at least one inner plate by a second pin that extends through the first end plate and the at least one inner plate. The first end plate is rotatable relative to the at least one inner plate about a first pivot axis defined by the first pin. The second end plate is rotatable relative to the at least one inner plate about a second pivot axis defined by the second pivot pin.

In one general aspect, a computing device can include a lid, and a base coupled to the lid by a hinge. The hinge can include a first disc including a first pin coupled to the lid and an inner surface. The hinge can include a second disc including a second pin coupled to the base and an outer surface. The first disc can be concentric with and can partially surround the second disc. The hinge can further include a friction element disposed between the inner surface of the first disc and the outer surface of the second disc. The first disc can be configured to rotate about the second disc.

Each of two turret-shaped modules has a generally hemispherical configuration facing outwardly and a disk-shaped flange facing inwardly. The flanges are similarly configured with a planar surface and circular periphery. An axial bore extends centrally through each module parallel with the planar surfaces for receiving and supporting first and second cylindrical objects. A V-band encompasses the flanges with the planar surfaces in contact with each other. The clamp includes a rotatable member to loosen and tighten the clamp. In this manner, the flanges and modules are rotated and fixed with respect to the received and supported cylindrical objects.

A hinge for pivotally joining a first frame member and a second frame member of a frame of a stroller may include a first housing portion, a second housing portion, a release actuator and a locking member. The first housing portion may be operably coupled to the first frame member. The second housing portion may be operably coupled to the second frame member. The release actuator may be configured to operate to enable the hinge to shift between a locked state and an unlocked state. The locking member may be configured to move in an axial direction responsive to shifting between the locked state and the unlocked state. The external periphery of the locking member may include a first incline surface that engages both the first housing portion and the second housing portion in the locked state.

The present disclosure relates to a gapless hinge mechanism including an external gear plate, an internal gear assembly, a gap elimination unit, a cover plate, a driving wheel, and an axial limiting member. The external gear plate may be crimpedly connected to the internal gear assembly. A first internal hole may be disposed at a center of the external gear plate, and a central boss may be disposed at an opening of the first internal hole. A space A may be defined by the center boss and a central internal hole of the internal gear assembly. A gap elimination unit may be disposed in the space A. The present disclosure provides a miniaturized gapless hinge mechanism which not only provides a rotation function, but also eliminates loose gap in the rotation direction, solves the problem of loose feeling of the mechanism, and avoids problems such as noise due to vibration. Compared with a planetary gear transmission reduction mechanism with a small tooth error commonly used in real life, the device of the present disclosure has the characteristics such as more ingenious structure, small overall volume, and small eccentricity, etc.
