DETAILED DESCRIPTION

A lockset of the utility model is applicable to an electronic device, and is connected to a lock hole on the electronic device. The electronic device is preferably a portable electronic device, such as, but is not limited to, a notebook computer, a tablet computer, a mobile phone, an e-book, a digital frame, a global positioning system (GPS) navigator, a mobile network device, a personal digital assistant, a digital walkman, or an electronic dictionary.

In different embodiments, the lockset may vary. In an embodiment shown inFIG.1AtoFIG.2B, a lockset800of the utility model includes a housing100, at least one hook200, a driving device300, and a lock body400. The housing100has a front opening110at an end. Each hook200is disposed in the housing100, and is rotatable relative to the housing100. In this embodiment, two hooks200are disposed in the housing100, and are rotatable relative to the housing100along a plane parallel to an X-Y plane, and are scissor-shaped. However, in a different embodiment, there may be only one hook200used with another non-rotary fixing member, and is not limited to the scissor shape. Each hook200includes front end portions210and rear end portions220. At least part of the front end portions210extends out of the front opening110. A hook portion211laterally extending is disposed at an end of each front end portion210. The rear end portions220extend in a direction opposite to the direction in which the front end portions210extend. An X axis, a Y axis, and a Z axis are orthogonal.

In an embodiment shown inFIG.2AandFIG.2B, the driving device300includes a force application member310and a driving member320. The force application member310is rotatable along a plane parallel to an X-Z plane, and includes a force bearing portion311partially disposed inside the housing100and a force application portion312disposed inside the housing100. The force bearing portion311is connected to the force application portion312by penetrating the housing100, and is rotatable with the force application portion relative to the housing100. More specifically, in the embodiment shown inFIG.2A, the housing100has a rear opening120. The force bearing portion311is connected to the force application portion312by penetrating the housing100through the rear opening120. A part of the force bearing portion311is exposed from the housing100. However, in a different embodiment, the force bearing portion311is completely disposed in the housing100, or at least does not protrude out of the housing100. A user may rotate the force bearing portion311with a screw driver or the like.

In an embodiment shown inFIG.1AtoFIG.2B, the driving member320is disposed in the housing100, and is rotatable with the force application portion312. The lock body400is disposed on a side of the driving device300. The lock body400restricts a movement of the driving device300when locked. More specifically, in an embodiment shown inFIG.3AandFIG.3B, the force application portion312is a disc having a plurality of protruding members314disposed at a peripheral edge. The lock body400includes a snapping member410which is movable along a Y-axis direction. When the lock body400is locked, an end of the snapping member410extends into the plurality of protruding members314to restrict the rotation of the force application member310. The snapping member410includes a protruding post411. However, in a different embodiment, the force application portion312is not limited to the disc having a plurality of protruding members314disposed at the peripheral edge, as long as the snapping member410can be limited by means of shape matching or friction. For example, a plurality of holes may be provided on the peripheral edge of the force application portion312for insertion of the protruding post411. In other words, when the lock body400is locked, an end of the snapping member410is snapped in the force application member310to restrict the rotation of the force application member310. In this embodiment, the lock body400is a key lock used with a key900. For example, the lock body400communicates with the outside of the housing100through a side opening130, so as to insert and operate the key900.

In the embodiment shown inFIG.2AandFIG.2B, the driving member320is disposed in the housing100, and is rotatable with the force application portion312to selectively move between the rear end portions220, so as to change an opening width of the front end portions210. In this embodiment, the force application portion312has a driving portion313. An end321of the driving member320is movable in the Y-axis direction to be snapped in the driving portion313, so that the driving member320is rotatable with the force application member310. More specifically, the driving portion313is polygonal. The end321of the driving member320is a polygonal cylinder having an outer contour matching the driving portion313. Thus, when the end321of the driving member320is inserted into the driving portion313, snapping achieved on the X-Z plane, so that the driving member320is rotatable with the force application member310. However, snapping is not achieved in the Y-axis direction, and therefore relative movement is allowed. However, in a different embodiment, the driving member320and the driving portion313may be other objects mated with each other, and may include a plurality of driving members and driving portions.

Further, in an embodiment shown inFIG.2A,FIG.2B,FIG.4AtoFIG.4C, the driving device300further includes a displacement restriction member330fixed in the housing100. The displacement restriction member330therein has an accommodating space140extending along the Y axis. A sidewall thread144is disposed on a sidewall of the accommodating space140. The driving member320is disposed in the accommodating space140. The driving member320is a circular cylinder having a driving member thread324on a side surface that is mated with the sidewall thread144. By means of the abutment between the sidewall thread144and the driving member thread324, when the force application member310is rotated, the driving member320is rotated with the first driving member. In this way, an end322of the driving member320that faces the rear end portions220is moved in the Y-axis direction for extending different depths between the rear end portions220. The end322of the driving member320that faces the rear end portions220has an inclined plane, helping the end322move in the Y-axis direction for extending different depths between the rear end portions220and spread the rear end portions220. However, in a different embodiment shown inFIG.4D, the accommodating space140may be directly provided in the housing100. That is to say, the sidewall thread144is directly disposed on an inner side of the housing100. In this case, the displacement restriction member330is omitted. In addition, the lockset800further includes an elastic member500, such as a rubber ring. The elastic member is configured to provide an elastic force so that the rear end portions220approach each other.

In an embodiment shown inFIG.5A, a user may rotate the force application member310in a direction, so that the end322of the driving member320that faces the rear end portions220is moved in the Y-axis direction to escape from the position between the rear end portions220. In this case, by means of the elastic force of the elastic member500, the rear end portions220can approach each other, so that the opening width of the front end portions210is reduced, thereby inserting the front end portions into a lock hole720. In an embodiment shown inFIG.5B, after the front end portions210are inserted into the lock hole720, the user may reversely rotate the force application member310, so that the end322of the driving member320that faces the rear end portions220is moved in the Y-axis direction to partially extend between the rear end portions220. Therefore, the rear end portions220can be moved away from each other, to increase the opening width of the front end portions210, thereby snapping the front end portions in the lock hole720. In this way, the user may further lock the lock body400(referring toFIG.2A) to fix the front end portions210, so as to achieve locking. In another embodiment shown inFIG.5C, after the front end portions210are inserted into a lock hole710, the user may rotate the force application member310, so that the end322of the driving member320that faces the rear end portions220is moved in the Y-axis direction to extend between the rear end portions220to a greater extent. In this case, the rear end portions220can be moved away from each other, to further increase the opening width of the front end portions210, thereby snapping the front end portions in the larger lock hole710. Then, the user may further operate the lock body400to achieve locking.

In a different perspective, in the lockset800of the utility model, the opening width of the hook200is adjusted by rotating the driving device300. Since the force application member310and the driving member320of the driving device300achieve mating and snapping by using the gear, the thread, and the like, the opening width of the hook200may be controlled according to a degree of rotation. Since the rotation is substantially a continuous operation, continuous control of the opening width of the hook200can be achieved. Therefore, the utility model is applicable to lock holes of different sizes and is convenient to use.

In the foregoing embodiments, the lock body400is a key lock. However, in an embodiment shown inFIG.6A to8Bor another different embodiment, the lock body400may be a different lock, such as a combination lock. In an embodiment shown inFIG.7A to8B, the lock body400is a combination lock. The snapping member410includes a lock shaft rod. More specifically, when the lock body400is locked, an end of the lock shaft rod of the snapping member410extends into the plurality of protruding members to restrict a movement of the driving device300, so as to restrict the rotation of the hook200.
