A receiving cavity 313 is further formed in a middle region of the link main body 311, the receiving cavity 313 penetrates through the link main body 311 from a width direction of the link main body 311 (i.e., a direction corresponding to a Y arrow in the drawing), and a space capable of completely receiving the power steel sheet 43 is formed in the link assembly 30 by sequentially connecting a plurality of such links 31, as shown in fig. 2, and the power steel sheet 43 is fixed in the space, and the link assembly 30 deforms along with the deformation of the power steel sheet 43.

In practical applications, the connecting block 46 may be configured to have the same shape as the link 31, but two connecting protrusions are provided on the connecting portion 312, so that the power steel sheet 43 may completely penetrate through the entire band 41, and therefore, only one power steel sheet 43 needs to be provided for the band 41 with such a structure.

In this embodiment, the link assembly further includes a limiting member 32 for cooperating with the link portion 312 to realize the rotational connection, a limiting hole and a mounting hole are disposed on the limiting member 32, wherein the limiting hole and the mounting hole are respectively disposed on two end positions of the limiting member 32, and the limiting hole is a long-strip-shaped limiting hole, so that the connecting protrusion can realize the movement in the limiting hole by a certain distance, thereby ensuring the rotational displacement when the link 31 rotates.

In practical application, connecting portion 312 is for following length direction follows the terminal surface of chain link is protruding connection arch and the stationary blade that forms outward, when the equipment, connection arch with spacing jogged joint, the mounting hole is connected with the connection arch on other chain links.

In practical application, the fixing sheet is arranged to fix the support sheet 44 to fix the flexible display module 45, and to prevent the link from reversely bending, that is, when the link 31 is reversely bent, firstly, the limiting member contacts and collides with the fixing surface to prevent the link from further reversely bending, and meanwhile, since the length of the limiting hole 322 in the limiting member 32 is also matched with the planar reverse bending, when the limiting member rotates along the connecting protrusion to contact with the fixing sheet, the connecting protrusion 3122 of the connecting portion 312 is also just located at the topmost end of the limiting hole 322 to prevent the link 31 from no longer laterally displacing, thereby locking the rotation radius, and such a matching manner realizes the control of the reverse rotation.

In this embodiment, the wearable device further includes a silicone sleeve 47, where the silicone sleeve 47 is disposed on the surface of the link assembly 30, and wraps the flexible display module 45 on the support sheet 44, as shown in fig. 10.

The invention provides a chain link assembly and wearing equipment thereof, the chain link assembly comprises a limiting piece and at least two chain links which are sequentially connected through the limiting piece, each chain link comprises a chain link main body and a connecting part which is formed by respectively extending and protruding outwards from two opposite end surfaces in the length direction of the chain link main body, the chain links are connected with the connecting parts in a matching way through the limiting piece to realize the rotary connection between the chain links, a containing cavity is also arranged on the middle area of the chain link main body, the containing cavity penetrates through the chain link main body from the width direction of the chain link main body, through the chain link assembly formed by the chain links, the chain links are connected in a rotating way, so that the wearing equipment can realize the bending folding at any angle, has smaller deformation degree and can well adapt to the 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 chain link is simple in structure, so that the processing technology is simple, and the cost of producing the wearable equipment is greatly reduced.
