Abstract
A chain structure for a screen device comprises a plurality of chaining unit members (10). Each chaining unit member comprises a bridging portion (11), and comprises a first pivotal connection portion (12) and a second pivotal connection portion (13) that are disposed on two opposite sides of the bridging portion. The chaining unit members are connected by means of the first pivotal connection portions and the second pivotal connection portions, so as to form a chain structure (1). By means of the structure arrangement, the plurality of chaining unit members is serially connected; in this way, when the chain structure slides in the screen device, by means of the swing and pivotal movement of the bridging portions, the problems in the prior art that a member is likely to deform, the slide is not smooth and there is noise can be avoided.
