Abstract: A server device including a chassis having an accommodating space and an opening, a least one server having a front part and a back part, and at least one connecting rod assembly having a first connecting rod, a second connecting rod, and a third connecting rod. The server may be located in the accommodating space and be drawable from the opening. The first connecting rod is pivoted on the front part of the server. The second connecting rod is pivoted on the back part of the at least one server. An end of the third connecting rod is pivoted on the first connecting rod, and another end of the third connecting rod is pivoted on the second connecting rod. The first connecting rod is rotatable relative to the server to move the third connecting rod, so that the second connecting rod is fastened to the chassis.

Abstract: An electromagnetic interference (EMI) shielding device includes first and second housing portions assembled along an assembly direction, at least two spaced-apart female fasteners fixed to one of the first and second housing portions, a plurality of male fasteners corresponding in number to the female fasteners and spacedly fixed to the other one of the first and second housing portions, and at least one grip member connected to one of the first and second housing portions. The grip member is applied with a force along the assembly direction or along a direction opposite to the assembly direction to engage or disengage the male and female fasteners.

Abstract: A door assembly includes a door base, a door disposed pivotally on the door base for covering openably the door base, and a locking mechanism. The locking mechanism includes a first body biased to move relative to the door base in a first direction, a first engaging portion disposed at the first body, a pushing portion disposed at the first body, a second body disposed at the door, and a second engaging portion disposed at the second body. A lock is operable to move the first body relative to the door base in a second direction opposite to the first direction. The first engaging portion is biased to move in the first direction to thereby engage the second engaging portion, so as to lock the door at a locked position for covering the door base.

Abstract: A strap mechanism for drawing an electronic device from a cage in a first direction is disclosed. The strap mechanism includes a first rail. The first rail includes a first locking part for connecting with a lateral surface of the electronic device and disposed inside the cage in a slidable manner, and a first handle part connected to an end of the first locking part. A first slot is formed on the first handle part. The strap mechanism further includes a strap. A first end of the elastic strap is inserted inside the first slot. The strap is for contacting against the first handle part so as to provide a component force in the first direction and in a second direction perpendicular to the first direction to the first handle part when a deformation of the elastic strap is generated by being pulled in the first direction.

Abstract: A quick-releasing structure is applied to a casing for installing a hard disk device. The quick-releasing structure comprises a spring plate, a handle, and two shock-absorbing members. The spring plate is connected to the casing; the two ends of the handle are coupled to the spring plate; two shock-absorbing members are connected to the two ends of the spring plate for fastening the hard disk device and producing shock-absorbing effect. By pulling the handle, the two ends of the spring plate being moved away from the casing, and the two shock-absorbing members being moved to release the hard disk device.

Abstract: An electronic device and a dust-proof mechanism thereof are disclosed. The electronic device is electrically connected to a charger and includes a power source, a housing with a hole and a sliding track and a dust-proof mechanism. The dust-proof mechanism includes a pivot cover and a slide cover. The pivot cover includes a pivoting side and a rotating side. The pivoting side is rotatably installed adjacent to the hole of the housing. The slide cover is disposed on the sliding track and movably installed adjacent to the rotating side. When the charger does not enter the hole, the pivot cover is disposed in a closed position to cover the hole and the slide cover is adjacent to the rotating side of the pivot cover. When the charger is inserted into the hole and pushes the pivot cover, the pivot cover is disposed in an opened position and the slide cover is pushed until the charger is electrically connected to the power source.
