The watchband provided by the embodiment of the invention comprises the connecting link assembly provided by the first embodiment, wherein the connecting link assembly comprises at least two connecting links which are sequentially connected, each connecting link comprises a link main body and limiting parts arranged on two opposite end faces in the length direction of the link main body, one end face of the two opposite end faces in the width direction of the link main body is provided with a notch, and the other end face of the link main body is provided with an extending part; the at least two connecting chain links are rotatably connected through the limiting parts, and the extending parts are arranged in the notches of the other connecting chain link.

In this embodiment, the connecting link assembly further includes a connecting piece for cooperating with the limiting portion to realize the rotational connection, and the connecting piece is provided with a positioning hole and a limiting groove, wherein the positioning hole and the limiting groove are respectively disposed at two end portions of the connecting piece.

In practical application, spacing portion is for following length direction follows the terminal surface of connecting the link is the arch of evagination formation, when the equipment, protruding with the locating hole is connected, the spacing groove is connected with the arch on other connecting links.

in this embodiment, chamfers for bending and rotating the connecting link downward are further provided on both end portions of the stopper portion, which are two end surfaces of the stopper portion that are opposite to each other in the width direction of the connecting link.

In practical application, the end face provided with the chamfer 33 is not provided with the chamfer 33, and is also provided with the plane 34, the chamfer 33 is only arranged for the purpose of space avoidance and guiding rotation of the connecting link 31 during rotation, the plane is arranged to be convenient for the equidistant arrangement and distribution of the connecting links 31 during assembly, then when the connecting links 31 are welded on a steel sheet, when the connecting links 31 are bent reversely, the distance between the planes on the two connecting links 31 is increased, meanwhile, the bulge 316 of the limiting part 312 is also just positioned at the topmost end of the limiting groove 322, so that the connecting links 31 do not transversely displace any more, and the rotating radius is locked, and the matching mode is combined with the hardness control of the steel sheet to realize the limitation of reverse rotation.

The wearable device comprises the connecting link component, and the connecting link component is connected through mutual rotation of a plurality of connecting links, so that the wearable device also realizes random shape change and random adjustment of a bending angle, and the matching mode of the notch and the extension part is installed, so that the wearable device is convenient to position and assemble, and the problem of preventing twisting is solved.

The invention provides a connecting link component, a watchband and wearable equipment, wherein the connecting link component comprises at least two connecting links which are connected in sequence, each connecting link comprises a link main body and limiting parts arranged on two opposite end surfaces in the length direction of the link main body, one end surface of the two opposite end surfaces in the width direction of the link main body is provided with a notch, the other end surface of the link main body is provided with an extending part, when the connecting link component is assembled, at least two connecting links are rotatably connected through the limiting parts, the extending parts are arranged in the notches of the other connecting links, the connecting link component formed by the connecting links is rotatably connected, so that the wearable equipment can be bent and folded at any angle, has small deformation degree and can be well adapted to hand shapes of various users, the phenomenon of skin adhesion after the user wears the clothes does not occur, so that the use experience of the user is greatly improved; furthermore, the connecting chain link is simple in structure, so that the processing technology is simple, and the cost of producing the wearable equipment is greatly reduced.
