  • Patent number: 11193527
    Abstract: A supporting device includes a first and a second support, a fixed washer, and a threaded fastener. The first support has a threaded structure extending along a rotation axis, and a first engaging structure. The second support is pivotally connected to the first support relative to the rotation axis and has a through hole aligning with the threaded structure. The fixed washer includes a washer portion and a second engaging structure. The washer portion is disposed on the second support and aligns with the through hole. The second engaging structure passes through the through hole to engage with the first engaging structure. The threaded fastener presses against the washer portion and passes through the washer portion and the through hole to engage with the threaded structure. When the second support and the first support rotate relatively, the fixed washer and the first support remain fixed relative to the rotation axis.

  • Patent number: 10340673
    Abstract: An electronic device includes a support frame, an electronic unit and a cable. The support frame includes a frame body and a first cable management unit. The frame body has a cable management recess and a cable management hole, wherein the cable management recess communicates with the cable management hole. The first cable management unit is connected to the frame body and rotatably located in the cable management recess. The electronic unit is disposed on the frame body. The cable has a first end and a second end opposite to the first end. The first end is connected to the electronic unit and the second end passes through the cable management hole to enter the cable management recess. The first cable management unit limits the cable in the cable management recess. When the cable is pulled to move, the first cable management unit rotates along with the cable.

  • Publication number: 20170072182
    Abstract: A needleless connector comprises a lid, a containing seat, and a flexible valve. One end of the lid is connected to one end of the containing seat, the interior of the lid and the interior of the containing seat form a space. The flexible valve is disposed in the space, and the flexible valve has a closed end and an opening end. The closed end is disposed in the inserting hole of the lid, and the opening end toward the closed end is formed inward with a groove. The flexible valve is defined in sequence as a head portion, a shoulder portion, a bending portion, and a supporting portion from the closed end to the opening end. The outer diameter of the head portion is smaller than the outer diameter of the bending portion. A shoulder portion is connected between the head portion and the bending portion.

  • Publication number: 20130039015
    Abstract: A hanging mechanism is for hanging an electronic device on a support wall. The hanging mechanism includes a fixing pad, first and second linkage rods, first arm and second arm rods, and first and second hanging rods. The fixing pad is detachably fixed onto the electronic device. The first linkage rod is pivoted to a first side of the fixing pad and the first arm rod. The second linkage rod is pivoted to a second side of the fixing pad and the second arm rod. The first hanging rod is pivoted to the first arm rod. The second hanging rod is pivoted to the second arm rod and rotatably intersects with the first hanging rod. The second hanging rod is for hanging on the support wall with the first hanging rod. When the first and second linkage rods rotate relatively, the first and second hanging rods rotate relatively.

  • Publication number: 20100271762
    Abstract: A shielding device provides a housing, a lid and a connection hole, and the shielding device is fireproof, insulating, and easy for wire assembly. The housing is disposed on an electronic device and surrounds the electronic device. The housing has at least one opening corresponding to a connector of the electronic device. The perimeter of the lid is connected to the perimeter of the opening, so that the lid can cover the opening to shield the connector. The connection hole is disposed on at least one of the perimeter of the opening and the perimeter of the lid. When the lid covers the opening of the housing, at least one connecting wire of the electronic device can extend outwardly through the shielding device via the connection hole.
