Due to the adoption of the structure, the chain links are sequentially connected into the long-strip drag chains with different use requirements, cables to be installed are placed in the containing space formed by the drag chains, and finally the packaging block chains with the corresponding lengths, which are connected with each other through the flexible parts, are clamped with the corresponding drag chain links one by one; secondly, due to the arrangement of the structure, when the drag chain is disassembled or the cable is replaced/supplemented, the whole packaging block can be quickly disassembled and separated from the drag chain like a tearing buckle by pulling the flexible piece on the packaging block, so that the disassembling efficiency of the drag chain is greatly improved, and the working progress is accelerated.

Furthermore, the chain link comprises two connecting plates which are arranged in parallel, each connecting plate comprises a first connecting part and a second connecting part, and the first connecting part and the second connecting part are integrally formed; the first connecting part is provided with a connecting hole, and the second connecting part is provided with a boss; and the connecting hole on the first connecting part is matched with the boss on the adjacent connected chain link, and the boss on the second connecting part is clamped with the connecting hole on the adjacent connected chain link.

Furthermore, the centers of the connecting holes and the bosses on the same connecting plate are positioned on the same straight line; and the first connecting end part of the first connecting part and the adjacent chain link is in a semi-circular arc shape.

furthermore, the same side part of the two parallel connecting plates is connected with a fixed plate, and the two connecting plates and the fixed plate form a U-shaped structure; the other side parts of the two connecting plates are sealed into a ring through a packaging block.

Furthermore, the packaging block comprises a clamping part and a sealing part, and the clamping part and the sealing part are of T-shaped structures; and a connecting groove is arranged on the side part of the connecting plate and is matched with the clamping part for installation.

Due to the adoption of the mechanism, the combined structure of the invention is compact, after the chain links are connected, the mutual rotation between the chain links can be realized under the mutual rotation action of the connecting holes and the circular bosses, so that the bending flexibility of the formed drag chain is ensured, the use environment requirement is met, the damage of mechanism parts caused by the mutual acting force between the chain links is avoided, the cable can be limited in the accommodating space formed by the cable and the drag chain link by the packaging block, and the phenomena that the normal use of equipment is influenced and the running environment of the equipment is complicated due to the winding of the cable when the cable is out are avoided.

According to the combined drag chain, the width of the sealing part is equal to the parallel distance between the two connecting plates; the end of the sealing part is fixedly connected with one end of the flexible part, and the other end of the flexible part is connected with the clamping part on the packaging block which is installed adjacently.

Furthermore, the flexible part is a strip-shaped brace made of the same material as the packaging block; a cavity for accommodating the brace is arranged in the packaging block; the connecting end part of the brace and the clamping part can slide in the cavity.

furthermore, the brace is the type of falling T structure, the structure cooperation setting of cavity structure and brace, the encapsulation piece that adjacent connection can be connected into the cluster through the brace.

Due to the adoption of the structure and the structural mode between the flexible piece and the packaging blocks, the transformation of the whole required action space of the drag chain in the bending process can be further adapted, the situation that the packaging blocks are easy to fall off due to the mutual dragging among the packaging blocks in the process of bending the drag chain is prevented, and the structural stability of the drag chain in the using process is further ensured by the design of the structure.

in summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:

1. The combined drag chain has simple structure and convenient installation and use;

2. By adopting the tearing structure principle, the drag chain can be quickly mounted and dismounted so as to place or adjust the cable, and the working efficiency of using the drag chain is greatly improved;

3. The structural stability is good;

4. The practicability is strong.
