Abstract: A case assembly includes a case and a locking device. The case includes a housing with an opening and at least one cover movably disposed on the housing for covering the opening. The housing includes a side plate, and the cover includes a restricting unit. The restricting unit proximal to the side plate extends outwardly along an inner surface of the cover and protrudes from an outer wall of the side plate when the cover covers the opening. The locking device is mounted on the side plate of the housing to move between an unlocked and a locked positions. The locking device can block the restricting unit of the cover when in the locked position for preventing the cover from being easily detached from the housing.

Abstract: A housing includes a housing body formed with an engaging groove and a carrier device disposed in the housing body. The carrier device includes a carrier frame and a latching assembly. The carrier frame is configured to carry an electronic component and includes a pivoting sidewall rotatably pivoted to the housing body. The carrier frame is rotatable between a first position, where the carrier frame is disposed in the housing body, and a second position, where the carrier frame is pivoted out of the housing body. The latching assembly is disposed on the pivoting sidewall and is releasably engaged to the engaging groove so as to position the carrier frame at the second position.

Abstract: An electronic device includes a housing, a button module and a control board. The button module includes a button cap having a space, a follower movably disposed in the space, and an elastic member. A movable cavity is defined by a portion of the follower located in the space and an inner surface of the button cap. The elastic member is disposed in the movable cavity, and two ends of the elastic member respectively abut against the inner surface of the button cap and the follower. An amount of compression of the elastic member is varied in response to the size of the movable cavity. When the button cap is in an unpressed state, the elastic member has a first amount of compression and generates a restoring force; when the button cap is in a pressed state, the follower abuts against a switch unit of the control board correspondingly.

Abstract: An electronic apparatus includes a housing having first and second cover bodies covering opposite first and second ends thereof, and a switch device including a support member, and a switch assembly mounted on and slidable relative to the support member and having first and second contact points. When one of the first and second cover bodies covers one of the ends of the housing and pushes one of the first and second contact points with the other one of the first and second contact points being unblocked, the switch assembly is placed in an OFF state. When the first and second cover bodies cover the ends of the housing and push the first and second contact points toward each other, the switch assembly is switched from the OFF state to an ON state.

Abstract: A plugging device includes a supporting frame having two opposite side plates disposed between front and rear ends thereof, at least one slide member adapted to be connected to one side of an electronic component and connected slidably to an inner surface of one of the side plates, and an operating member having at least one lever that includes a fulcrum portion connected pivotally to one of the side plates. When the operating member is pivoted rearwardly about the fulcrum portion, the slide member together with the electronic component is driven to slide relative to the supporting frame in a forward direction for plugging a plug electrical connector of the electronic component into a socket electrical connector.

Abstract: A hinge for pivotally interconnecting first and second brackets includes a shaft having a shaft body extending through the first and second brackets and formed with an engaging end portion proximate to the second bracket, a fixing member connected to the engaging end portion, a ratchet sleeved rotatably on the shaft body between the fixing member and the second bracket, a friction mechanism having an urging unit sleeved on the shaft body between the ratchet and the fixing member and pressing the ratchet toward the second bracket, and a brake mechanism disposed on the second bracket and having a pawl member releasably engaged to the ratchet.

Abstract: The instant disclosure discloses a fixing structure of a data access device having a fixing tray and a handle. The fixing tray includes at least one fixing latch and at least one elastic member. One end of the fixing tray is a pivot and two hooks. The distance between the fixing latch and the pivot is shorter than that between the elastic member and the pivot. The other end of the fixing tray is an inserting section. One end of the handle is a hinge section, from which two cams are extended. The other end of the handle is an operational pull. The hinge section and the operational pull are connected by a connecting rod. The hinge section pivotally connects to the pivot. A fixing case with the fixing structure of a data access device is disclosed.

Abstract: A torsion adjusting structure, which is installed on a shaft and a carrying member pivoted on the shaft, includes a gear, a pair of friction washers, and a linkage assembly. The shaft passes through the gear and the friction washers respectively abutted on two opposite surfaces of the gear. The linkage assembly installed on the carrying member has an engaging portion. The linkage assembly is adjusted between an engaging position and a separating position. When the linkage assembly is at the engaging position, the engaging portion engages with the gear for enabling rotation of the carrying member to rotate the gear to rub the friction washers, thereby providing the carrying member with an additional torsion. When the linkage assembly is at the separating position, the engaging portion separates from the gear for maintaining the relative position between the gear and the friction washers.

Abstract: A screen supporting device includes a shaft, a bracket, and a torsion adjusting structure. The bracket and the torsion adjusting structure are pivotally on the shaft. The torsion adjusting structure has a limited washer and a torsion spring. The shaft passes through the limited washer and the torsion spring, and two ends of the torsion spring are respectively inserted into the bracket and the limited washer. Thus, when the bracket pivots by being forced, the shaft and the limited washer maintains the position thereof to cause that the relative position of the ends of the torsional spring, which respectively inserted into the bracket and the limited washer, is changed to provide the bracket with an additional torsion. Therefore, the instant disclosure provides the supporting device capable of the torsion variable function.

Abstract: A case fixing mechanism includes: a fixing device, located on a first case part; an assembling part, for containing the fixing device; a combination device, provided on the second case part; and a control device, for controlling the combination device to be in a first location or a second location. The combination device fixes the first case part and the second case part when the combination device is in the first location. The combination device enables the first case part to be separated from the second case part when the combination device is in the second location. By this mechanism, the first case part can be easily removed from the second case part in simple steps.
