    Abstract: The present invention relates to a portable safety door stopper and a room door blocking method. The portable safety door stopper comprises a stopper for attaching to the inner side of a door, a base laid flatwise on the ground, and a supporting post rotatably connected between the stopper and the base, wherein a locking hook component is built in the stopper, and the stopper can always cling to a set position on the inner side of the door through the locking action of the locking hook component, so that the installation of the safety door stopper is realized; an alarm module can be built in the base to achieve an alarm reminding function at the same time.

    Abstract: An anti-surge structure built in switches includes three metal-oxide varistors disposed in an insulating body in stair-like arrangement. The metal-oxide varistors further has an insulating band surrounding a middle metal-oxide varistor and defining four isolated insulating areas within the insulating body, so as to avoid high voltage flashover and to protect the structure from external impacts. With the stair-like arrangement, each metal-oxide varistor has a connecting area for both ends of a metal strap to be welded thereon by low-temperature solder paste. When the low-temperature solder paste are melted by heat, a compressed spring element thereof is ejected to displace a pushing element thereof and to further detach two connecting points of the structure, so as to break a circuit connected by the structure.

    Abstract: The present invention discloses a display device frame, including at least a metallic back panel and a plastic outer frame. A side of the metallic back panel is extended with a lateral edge, the metallic back panel is formed integrally with the lateral edge, and an included angle is formed between an inner side of the metallic back panel and an inner side of the lateral edge. The lateral edge includes two side surfaces; whereas, the plastic outer frame is provided with two clip parts and encloses the lateral edge. The two clip parts are in a clipping state to clip the two side surfaces. The present invention removes the front frame in a conventional large display device frame, allowing the plastic material to enclose the periphery or a part of the large display device frame, which achieves the trends and advantages of thinning the large display device.
