Fig. 2 is a schematic structural diagram of a chain assembly provided in this embodiment, wherein the chain assembly 20 is used for a wearing connection of a wearable device; the chain assembly comprises at least two connecting chain links 21 and connecting pieces 22 with the number matched with that of the connecting chain links 21, wherein the connecting pieces 22 are arranged between every two adjacent connecting chain links 21; the connecting link 21 comprises a link body 211 and connecting parts 212 arranged at two ends of the link body 211 in the width direction of the chain assembly, and the connecting parts 212 are rotatably connected with the connecting pieces 22; the connecting part 212 of the connecting link 21 is provided with a second extending part 213, the extending directions of the first extending part 221 and the second extending part 213 both extend inwards along the width direction of the chain assembly, and in the height direction of the chain assembly, the first extending part 221 is located above the second extending part 213; the first extension part 221 and the second extension part 213 are respectively and correspondingly provided with a limiting column 41 and a limiting hole 42, the extending direction of the limiting column 41 is the height direction of the chain assembly, the limiting column 41 is located in the limiting hole 42, the size of the limiting hole 42 is larger than that of the limiting column 41, and the matching between the limiting column 41 and the limiting hole 42 limits the rotating connection between the connecting link 21 and the connecting piece 22 within a preset angle range. Referring to fig. 3 and 4, fig. 3 and 4 respectively show a schematic structural view of the connecting link 21 and a schematic structural view of the connecting member 22 in the present embodiment.

The chain assembly 20 in this embodiment is comprised of connecting links 21 and connecting members 22. The connecting links 21 and the connecting pieces 22 are connected in a staggered manner, every two connecting links 21 are connected through the connecting pieces 22, and correspondingly, every two connecting pieces 22 are connected through the connecting links 21. The connection between the connecting link 21 and the connecting piece 22 is an articulated connection, in particular a rotary connection in the present embodiment. By rotational connection is meant that the connection between adjacent connecting links 21 and connecting pieces 22 is at least rotatable, which also allows a range of allowed translational movements between adjacent connecting links 21 and connecting pieces 22. The rotational connection is for the purpose of converting the chain assembly 20 from a flat state when not worn to a bent state when worn, or from a bent state when worn to a flat state when not worn.

The connecting portions 212 on the connecting links 21 are disposed on two opposite ends of the connecting links 21, wherein the two opposite ends are the ends in the width direction of the chain assembly 20. The connecting portions 212 provided at both ends ensure symmetry and stability of the connection of the chain assembly 20.

The width direction of the chain assembly refers to the vertical direction of the bendable direction of the chain assembly, and correspondingly, the bendable direction of the chain assembly can also be referred to as the length direction of the chain assembly, rather than the length and width of the chain assembly in the dimension. Generally, the dimension of the chain assembly in the length direction is always larger than that in the width direction, but the opposite is not excluded, and the embodiment is not limited thereto. Since the chain assembly in this embodiment can be adjusted according to the increase or decrease of the connecting links and the connecting members, the length and width of the chain assembly in terms of size are variable.

The connecting part 212 and the connecting part 22 form a rotating connection, the rotating connection can be a hinge connection, and the rotating connection between the connecting part 212 and the connecting part 22 can be realized through a hinge connection shaft by respectively arranging hinge connection holes on the connecting part and the connecting part; or, a connecting shaft is arranged on the connecting part 212 or the connecting part 22, and a connecting hole is arranged on the other connecting part, so that the connecting shaft and the connecting hole are matched to realize rotating connection, wherein the connecting shaft can be fixedly connected with the connecting part 212 or the connecting part 22, for example, through interference fit, or fixedly connected through gluing, welding, integral forming and the like. Here, the rotation connection between the connection portion 212 and the connection member 22 is used to realize the rotation therebetween, and may have no limit function or may be provided with a limit function to some extent, that is, the size of the hinge connection hole is set to be larger than that of the hinge connection shaft.

In order to realize the spacing effect of chain subassembly when wearing, can realize spacingly through limit structure. Wherein, limit structure specifically passes through: the part of the connecting member 22 rotatably connected with the connecting portion 212 is provided with a first extending portion 221, the connecting portion 212 of the connecting link 21 is provided with a second extending portion 213, the extending directions of the first extending portion 221 and the second extending portion 213 are the same, and both extend inwards along the width direction of the chain assembly, and the first extending portion 221 is located above the second extending portion 213; the first extension part 221 and the second extension part 213 are respectively and correspondingly provided with a limit column 41 and a limit hole 42, the extending direction of the limit column 41 is the height direction of the chain assembly, and the limit column 41 is positioned in the limit hole 42; in order to achieve the limiting effect, the size of the limiting column 41 is smaller than the size of the limiting hole 42, the limiting column 41 is located in the limiting hole 42, the limiting hole 42 can provide a moving space for the limiting column 41, and the moving space of the limiting column 41 realizes the limitation of the rotational connection between the connecting link 21 and the connecting member 22. The first extension part 221 and the second extension part 213 are arranged in the direction of extending inwards along the width direction of the chain assembly, so that the limiting structure can be hidden inside the chain assembly, and the integrity and the attractiveness of the appearance of the chain assembly are maintained. Referring to fig. 5, fig. 5 is a top view of the connecting link 21 of the present embodiment, when the position-limiting pillar 41 moves to a point a in the position-limiting hole 42, the movement of the position-limiting pillar 41 in the position-limiting hole 42 reaches a boundary, an angle between the connecting member 22 and the connecting link 21 is a first angle at the boundary, and the connecting member 22 and the connecting link 21 reach a limit straight state at the first angle without going beyond the limit straight state to cause a reverse folding; when the position-limiting column 41 moves to the point B in the position-limiting hole 42, the movement of the position-limiting column 41 in the position-limiting hole 42 reaches another boundary, the angle between the connecting member 22 and the connecting link 21 at the boundary is a second angle, and the connecting member 22 and the connecting link 21 reach a maximum bending state at the second angle without exceeding the state to cause excessive bending. Thus, the range from the first angle to the second angle, which is the predetermined angle range defined by the engagement between the position-limiting post 41 and the position-limiting hole 42, does not exceed the bending range between each adjacent connecting link 21 and connecting member 22 in the chain assembly 20. Generally speaking, the limit state of the chain assembly 20 at the first angle is a flat state, and the limit state of the chain assembly 20 at the second angle is a wearing state, and a reasonable angle can be set by referring to the shape and thickness of the wrist, or the angle range can be customized according to the wrist of different people, so that the wrist can fit different users.

In addition, the pivotal connection between the connecting links 21 and the connecting members 22 provides sufficient contact surface for the connecting links 21 and the connecting members 22 to prevent the chain assembly 20 from twisting in the width direction. The more sufficient the contact surface between the connecting link 21 and the connecting member 22, the more significant the effect thereof in preventing the widthwise twisting of the chain assembly 20.

Alternatively, in this embodiment, two first extending portions 221 may be symmetrically disposed on the connecting member 22, and are respectively located at two ends of the connecting member 22 in the width direction of the chain assembly, and the connecting portions 212 on two ends of the connecting link 21 are respectively disposed with one second extending portion 213, and the positions of the second extending portions 213 correspond to the positions of the first extending portions 221. Correspondingly, when two first extending portions 221 are symmetrically arranged on one connecting member 22, and one second extending portion 213 is respectively arranged on the connecting portion 212 at two ends of the connecting link 21, the two first extending portions 221 and the two second extending portions 213 may be provided with the matched limiting posts 41 and limiting holes 42, that is, two sets of limiting structures. The limiting columns 41 and the limiting holes 42 are arranged in one group, and the limiting effect can be further improved by arranging the limiting columns 41 and the limiting holes 42 on the two sides of the connecting link 21 and the connecting piece 22. Of course, when two sets of the position-limiting columns 41 and the position-limiting holes 42 are provided, the same set of the connecting parts 212 and the position-limiting columns 41 and the position-limiting holes 42 on the connecting parts 22 should be symmetrically provided.

That is, the arrangement positions of the position-limiting column 41 and the position-limiting hole 42 can be correspondingly changed, and when the position-limiting column 41 is arranged at the bottom of the first extension part 221, the position-limiting hole 42 is correspondingly arranged on the first extension part 221 on the connecting part 212; when the position-limiting column 41 is disposed on the top of the second extension 213 on the connection part 212, the position-limiting hole 42 is disposed on the first extension 221 disposed on the connection member 22.

Optionally, in this embodiment, the position-limiting column 41 may have various configurations, including, but not limited to, a configuration of fixedly connecting the position-limiting column 41 through a connecting hole, or a configuration of integrally forming. Wherein, fixed connection then includes gluing, welding and interference fit etc. integrated into one piece then can be technologies such as mould pressing, cutting etc. and form. According to the difference of the setting positions of the limiting column 41 and the limiting hole 42, the setting mode of the limiting column 41 is also different, specifically, when the limiting column 41 is arranged on the bottom of the first extending part 221 and the limiting hole 42 is arranged on the second extending part 213, the first extending part 221 is provided with a connecting hole, and the limiting column 41 is fixedly connected and arranged in the connecting hole; or, when the first extension part 221 is provided with the limiting hole 42 and the top of the second extension part 213 is provided with the limiting post 41, the second extension part 213 is provided with a connecting hole, and the limiting post 41 is fixedly connected and arranged in the connecting hole;
