Abstract: The present invention relates to the technical field of wearable devices, and in particular, to a watch band and a watch. The watch band includes: a plurality of sequentially connected chain elements, wherein a connecting portion and a connecting groove are provided on each of the chain elements, and the connecting portion is connected to the connecting groove on another adjacent chain element by means of a connecting mechanism; the connecting mechanism comprises a shifting block assembly and two ejector pin assemblies symmetrically provided at two sides of the shifting block assembly; an accommodating cavity and a placement groove penetrating the accommodating cavity are provided on the connecting portion; two oppositely arranged jacks are provided on the connecting groove; and the shifting block assembly is located in the accommodating cavity and the two ejector pin assemblies are located in the placement groove.

Abstract: The present invention has disclosed a magnetically-attracted buckle and a wearable device, which pertain to the technical field of strip-connecting structures. The present invention enables the first buckle and the second buckle to connect with each other by one hand, and the second magnetically-attracted member inserted into the hollow hampers the second buckle from being pulled out of the first buckle, avoiding the second buckle from easily separating from the first buckle.

Abstract: The present invention relates to the field of chain straps, in particular to an easy-to-disassemble length-adjustable chain strap, including: several middle chain links, wherein one end of each middle chain link is inserted with a connecting needle with an end exposed to the outside of the middle chain link; and one part of each pulling component is fitted into each middle chain link, and the other part of the pulling component is rotatably inserted into one edge link I correspondingly. According to the present invention, the length of the chain strap can be easily and conveniently adjusted by hand without using any tools under normal conditions. The way of adjusting the length of the chain strap is: gently pulling the edge link I outward with fingers and then rotating the same at a small angle to directly disassemble two adjacent middle chain links.

Abstract: Disclosed are a stress-resistant, creep-resistant, high-temperature resistant and high-insulation sheath material for a maglev train cable, and a manufacturing method and use thereof. A multiple chemical crosslinking structure is constructed by blending a functional polyvinylsilicone grease with ultra-high molecular weight polyethylene (UHMWPE) and a ceramicized silicone rubber as a cable material matrix and using electron beam irradiation. In addition, organic/inorganic fillers in the matrix can form physical crosslinking points in the material. A physical-chemical dual crosslinking structure is constructed in the matrix, which can limit the motion and relaxation of molecular chains and improve the interaction between the insulation layer and sheath layer and refractory layers such as fillers and mica tapes to avoid the relative displacement during the laying and operation and improve the high-temperature resistance, creep resistance and stress relaxation resistance of a UHMWPE cable sheath material.
