In addition, when the display device is in a flat state, the connecting rod is abutted to the innermost side of the through hole, meanwhile, the parallel edges of the limiting piece are in contact with the bottom surfaces of the first installation groove 3022 and the second installation groove 3032, and the limiting chain link 30 is bent towards the light emitting surface of the flexible display module, so that the whole watchband is prevented from being folded reversely, and the flexible display module can be prevented from being damaged.

In the present embodiment, as shown in fig. 7, the first clamping portion 302 further includes a first fixing groove 3024, and the second clamping portion 303 further includes a second fixing groove 3034;

when the chain link 30 is fixed on the window 211, the first protruding strip 212 arranged on both sides of the U-shaped groove passes through the first fixing groove 3024 and the second fixing groove 3034, and the first protrusion 3021 and the second protrusion 3031 extend into the U-shaped groove from the gap 214, so that the chain link 30 is further firmly fixed on the silicone sleeve 21, and an integrated structure of the chain link 30 and the silicone sleeve 21 is also realized.

In the invention, the terminal also comprises the link assembly and a screen assembly, wherein the screen assembly is arranged on at least two link structures on the watchband, and the wearable device is formed by a plurality of single-section links, so that the wearable device can be freely bent, the damage to the wearable device due to excessive bending deformation is avoided, the structure is simple, and the production cost is low.

In summary, the present invention provides a link assembly and a terminal, the link assembly comprises a silicone sleeve with a U-shaped groove and at least two links, the silica gel sleeve is provided with at least two windows, the chain link comprises a chain link body and a first clamping part and a second clamping part which are respectively arranged at the two ends of the chain link body, the chain links are respectively clamped and connected with two opposite sides of the window through the first clamping part and the second clamping part and are fixed on the window, because the watchband provided by the invention is formed by the links one by one and the links are connected by the silica gel sleeve, thereby make this kind of watchband can be crooked folding at will, can adapt to various users 'hand shape well, improved user's use and experienced to watchband simple structure, the production and processing of being convenient for makes the cost at the terminal of finished product lower.
