Abstract:
1. A cover mechanism comprising: a covering wherein a circular hole is formed, for covering an opening of a housing; a button installed inside the circular hole, a plurality of linear tracks being formed in the button, and adjacent linear tracks of the plurality of linear tracks being perpendicular to each other; a plurality of locking components disposed on sides of the covering, a first end of each locking component being disposed on a corresponding linear track of the plurality of linear tracks of the button in a movable manner, and a second end of each locking component for insertion into a corresponding indentation of the housing so as to lock the covering on the housing; a waterproof covering, the plurality of locking components being sandwiched between the covering and the waterproof covering; and a waterproof strip structure disposed between the waterproof covering and the housing for waterproofing, the waterproof strip structure being equally pressed so as to prevent liquid from leaking into the housing when the plurality of locking components stretch outwardly to insert into the corresponding indentations of the housing; wherein the plurality of linear tracks of the button drives the first end of each locking component to move away from a center of the button so that the second end of each locking component inserts into each indentation of the housing when the button rotates in a first direction, and the plurality of linear tracks of the button drives the first end of each locking component to move close to the center of the button so that the second end of each locking component separates from each indentation of the housing when the button rotates in a second direction opposite to the first direction.
