Abstract: A protective lock structure mainly including a main body, interior of which is disposed a control circuit assembled from a microprocessor, a memory, a high frequency transmitter circuit. The main body is connected to monitoring equipment, including an infrared camera, an infrared hot body sensing component, a sound pickup and speakers. Moreover, the main body is connected to an electric controlled lock, thereby enabling a cellular phone handset to dial out a telephone number and preset code, which the control circuit of the main body identifies and compares to ensure correctness before unlocking the electric controlled lock, thus providing a lock device with even greater safety and protective effectiveness.

Abstract: A buckle set on a cloth strip for a brassiere includes a male buckle and a female buckle. By the cloth strip, the buckle set can be directly stitched to the belts at two sides of the two cups of a brassiere. The male buckle has a round disk shape and has a pillar installed thereon. The lower end of the pillar has a lip portion. The female buckle has an oblong disk shape and a buckle hole in the middle part thereof. By the pillar of the male buckle pressing into and buckling with the buckle hole of the female buckle, the two belts are connected. The buckle hole on the female buckle has a long shape, The long axis of the buckle hole includes a flange at an inner periphery at one end so that one end of the buckle hole includes a guide groove. Thus, the pillar of the male buckle buckles with the buckle hole at the larger opening and then is pushed into the guide groove. Thus, the male buckle can be firmly fastened to the female buckle.
