Abstract:
The invention is to provide an electronic device battery pack removal and emplacement lock structure consisting of a compartment recessed in the case of an electronic device for the installing a battery pack, a minimum of one hook block proximal to its end at one side between the said battery pack and the said compartment, a minimum of one tapered polyhedron proximal to its other end, and a release structure internally disposed in the said compartment. As such, when the said battery pack is placed into the said compartment, the said tapered polyhedron pushes the said release structure until the said battery pack is completely ensconced within the said compartment, following which the said release structure automatically returns to its original position to restrain the said tapered polyhedron and render it immovable.
Abstract:
A wall fixture includes a post, a disc member, a cover plate and a locking piece. The post has a top end with a recessed hole and a bottom end with threaded socket. The disc member has a recessed groove formed therein. The recessed groove has a central protrusion portion extending upward of the same. A through-hole is formed in the protrusion portion. Two pairs of holes are provided on the plate member. One pair of the holes is specially designed to have a narrow portion and a large portion. A cover plate with a second rectangular hole therein, is provided on the disc member. When the post is mounted on the cover plate, the socket in the bottom end of the post, and both rectangular holes (of the cover plate and the disc member) are aligned.
