Abstract: A hinge includes a base, an arm, a mounting member, a hinge spring, a fixing pin member, and a damping device. Two ends of the arm are pivotably connected to the base and the mounting member, with the hinge spring exerting elastic force on the base and the arm. The damping device is mounted in the base and includes a fixed seat mounted in the base, a sliding block movably received in the fixed seat, a damping member mounted between the sliding block and the fixing pin member and abutting the base, and an elastic element. The sliding block includes a front portion facing the arm and a rear portion connected to the elastic element pressing against the fixed seat.

Abstract: A hinge includes a base, a crank, a bottom board, a crank engagement seat, and a fixed seat. The crank is pivotably connected to the base. The bottom board includes at least one retaining portion, a first rivet hole and a vertical elongated hole. The crank engagement seat is connected to the crank and located between the fixed seat and the bottom board. The crank engagement seat includes first and second through-holes and a second rivet hole. The fixed seat includes first and second adjusting holes. A first adjusting member is extended through the first adjusting hole and the first through-hole into the first rivet hole. A second adjusting member is extended through the second adjusting hole into the second rivet hole. The bottom board and the crank engagement seat can be slightly moved in the vertical direction. The crank engagement seat can be slightly moved in the horizontal direction.

Abstract: A hinge includes a base, an arm, and an elastic element. The base includes a recessed body having a rear wall with a supporting portion. The arm includes a pivotal portion and two cam portions. A first pin section of a fixing pin member is extended through the pivotal portion and connected to the base. The elastic element includes two front elastic portions, a rear elastic portion, two intermediate portions each interconnected to one of the front elastic portions, and two extensions each interconnected between the rear elastic portion and one of the intermediate portions. The front elastic portions press against the cam portions. The intermediate portions are connected to the base by a second pin section of the fixing pin member. The rear elastic portion abuts the supporting portion of the rear wall.

Abstract: A track device. The track device includes a first track, a second track, and a third track. The first track includes a first stop and an engaging block. The second track is slidably received in the first track. The second track includes a second stop for abutting against the first stop of the first track. The second track further includes a first engaging member on an end thereof. The first engaging member includes an extension member, the extension member including an engaging section and a foot. The third track is slidably received in the second track. The third track includes a second engaging member for abutting against a third stop of the second track. The second engaging member includes an engaging edge and a leg. The leg is pressable to allow disengagement of the engaging edge from a protrusion on the third stop.

Abstract: A fixing base structure of a slide track. The fixing base includes snap members, a guide channel, a retaining groove, and a retaining plate. The snap members are arranged on the back face of the fixing base. The guide channel is provided in the front face of a fixing base, and the retaining groove is matingly provided in the guide channel. In the structure of the guide channel, the guide channel is matingly provided with a retaining plate located above the retaining groove. When the slide track is mounted in the guide channel of the fixing base, the retaining plate elastically presses the slide track in the retaining groove, such that the slide track and the fixing base may have a better combination positioning effect therebetween.

Abstract: A retaining structure. The retaining structure includes a retaining member on a first track and a pressing block on a second track slidably received in the first track. The retaining member has two resilient legs and the pressing block has two protrusions. When the second track is mounted in the first track and pulled outward to a predetermined position, the legs of the retaining member press against inner sides of the protrusions of the pressing block to prevent inadvertent inward movement of the second track in the first track. When the second track in the predetermined position is pushed inwards by an appropriate force, the protrusions of the pressing block press to deform the legs of the retaining member to allow the protrusions of the pressing block to move across the retaining member, thus allowing inward movement of the second track in the first track.
