[0002] Drag chain, also known as wire and cable protection drag chain, is a device that restrains cables or wires or air pressure pipes and hydraulic pipes to facilitate their rotation and movement.
[0003] The patent with the patent authorization announcement number CN213655600U discloses a drag chain joint structure and a drag chain. The patent installs the hinged head of the upper cover plate in the hinged groove, and engages with two clamping grooves through two hinged short shafts, so that the upper cover plate is rotated and pressed into the clamping groove, and the clamping hook is clamped into the corresponding clamping hole. At the same time, the limit block on the upper cover plate enters the corresponding limit groove, so that the upper cover plate is further fixed, and the first chain plate and the second chain plate are connected. However, the drag chain provided by the patent still has shortcomings in actual use. When the drag chain is towing pipelines, since the pipelines are fixed in the drag chain, the pipelines are easily intertwined and entangled with each other, and they need to be re-combed when inspecting the pipelines, which is more troublesome.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0022] Embodiment 1: A drag chain, see Figure 1-Figure 3As shown, it includes a connecting block 1, the connecting block 1 is U-shaped, a first chain plate 2 is rotatably provided on one side of the connecting block 1, and a second chain plate 3 is rotatably provided on the other side of the connecting block 1. The first chain plate 2 and the second chain plate 3 are both made of engineering nylon material, which is more wear-resistant and durable, and is not easily damaged too quickly under long-term rotation friction. It has a longer service life and is lighter than metal materials. The first chain plate 2 and the second chain plate 3 are both connected to the connecting block 1 through rivet columns 4, and the adjacent first chain plates 2 or the adjacent second chain plates 3 are also connected through the rivet columns 4. Both ends of the rivet columns 4 are provided with annular protrusions 401 to To facilitate the insertion, removal and disassembly of the first chain plate 2 and the second chain plate 3, as well as the connecting plate 5, the first chain plate 2 and the second chain plate 3 are both installed with two upper and lower connecting plates 5 by welding on one side where the first chain plate 2 and the second chain plate 3 are close to each other, and a clamping block 6 is provided on the side of the connecting plate 5. The connecting plate 5 is installed and connected with the first chain plate 2 or the second chain plate 3 through the clamping block 6. A combing block 9 is installed on the connecting plate 5 by bolt connection. The combing block 9 is C-shaped to facilitate clamping of the pipeline of the column. The combing block 9 is made of PP plastic, has good toughness and high impact resistance, can clamp the pipeline without breaking easily, and is more durable.
[0023] When the drag chain is to be used, the pipeline can be combed by inserting the pipeline into the combing block 9, and the pipeline is not easily entangled with each other when the drag chain is bent. Subsequently, the adjacent first chain plates 2 and the adjacent second chain plates 3 are connected by the rivet columns 4, and the first chain plate 2 and the second chain plate 3 are installed on the connecting block 1 by the rivet columns 4. The first chain plate 2 and the second chain plate 3 can be limited by the annular protrusions 401 on the rivet columns 4 to prevent slipping during rotation. By aligning the connecting plates 5 on the first chain plate 2 and the second chain plate 3, a complete drag chain can be spliced; when the pipeline needs to be inspected, the drag chain can be disassembled and the pipeline can be inspected by buckling the first chain plate 2 or the second chain plate 3 from the left and right rivet columns 4.
[0024] Example 2: Based on Example 1, refer to Figure 3As shown, it also includes a hook plate 7, and the side of the connecting plate 5 on the second chain plate 3 is fixedly connected with the hook plate 7 by welding. The side of the connecting plate 5 on the first chain plate 2 is provided with a cavity 801, and the wedge block 8 is installed in the cavity 801 on the connecting plate 5 by welding. The lower part of the hook plate 7 away from the connecting plate 5 is provided with an arc portion 701, so that when the hook plate 7 slides toward the cavity 801, it can be better staggered with the wedge block 8 for clamping. The hook plate 7 and the wedge block 8 are both made of high manganese steel, which is more wear-resistant and not easy to wear. The hook plate 7 and the wedge block 8 will not wear each other due to frequent clamping and disengagement, so as to avoid unstable clamping.
[0025] In order to connect the two opposite connecting plates 5 , the hook plate 7 is inserted into the cavity 801 so that the hook plate 7 is engaged with the wedge block 8 , thereby fixing the connection between the two opposite connecting plates 5 .
[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
