[0024] Embodiment

[0025] Referring to Figures 1-4 , which is the first embodiment of the present utility model. This embodiment provides a structure-reinforced drag chain, including a plurality of drag chain sections 1. The drag chain sections 1 are connected to each other. The drag chain section 1 includes a chain plate 101, a connection hole 102, a side plate 103, a reinforcing rib 104, and a support rib 105. Two chain plates 101 are arranged relatively parallel to each other. Two connection holes 102 are respectively opened at the left and right ends of the chain plate 101. The side plate 103 is fixedly connected to one end of the outer side of the chain plate 101. The reinforcing rib 104 is fixedly connected to the middle part between the two connection holes 102. The support rib 105 is fixedly connected to the left side of the side plate 103. A rotating shaft 2 is fixedly installed in the inner cavity of the connection hole 102.

[0026] Specifically, adjacent two drag chain sections 1 are rotationally connected through the rotating shaft 2.

[0027] Furthermore, the rotating shaft 2 is used to connect multiple drag chain sections 1 into a whole, facilitating the traction and protection of the wire conduit.

[0028] Specifically, a clamping groove 3 is opened at the middle part of the top of the chain plate 101. A plugging rod 4 is fixedly connected to the top of the clamping groove 3. An installation groove 5 is opened at the middle part of the bottom of the chain plate 101. Fixed rotating shafts 6 are fixedly connected to the left and right sides of the inner wall of the installation groove 5.

[0029] Furthermore, through the settings of the clamping groove 3 and the installation groove 5, it is convenient to install two connecting plates 7 on both sides of the drag chain section 1, thereby facilitating the fixation of the wire conduit.

[0030] Specifically, the tops and bottoms of two parallel chain plates 101 are fixedly connected through connecting plates 7. One end of the connecting plate 7 is fixedly connected with a hinged rotating shaft 8. Installation holes 9 are opened at both ends of the hinged rotating shaft 8. The inside of the installation holes 9 is adapted to the fixed rotating shaft 6.

[0031] Further, insert the hinge rotating shaft 8 at the end of the connecting plate 7 into the installation groove 5, and insert the fixed rotating shaft 6 into the installation hole 9, so that the connecting plate 7 can rotate around the hinge rotating shaft 8 at the end, facilitating the control of the opening and closing of the connecting plate 7.

[0032] Specifically, a connecting portion 10 is provided at the other end of the connecting plate 7, and a clamping hole 11 is formed at the top of the connecting portion 10.

[0033] Further, turn the connecting portion 10 of the connecting plate 7 to the clamping groove 3, and insert the inserting rod 4 through the clamping hole 11 of the connecting portion 10 to fix the connecting plate 7.

[0034] Specifically, a fixed support bar 12 is provided inside the connecting plate 7, and a movable partition 13 is clamped at the middle part between the two fixed support bars 12.

[0035] Further, through the arrangement of the movable partition 13, it is convenient for the user to adjust the quantity and position of the movable partition 13 according to the usage requirements, so as to fix and protect wire pipes of various different specifications, making the wire pipe layout more concise.

[0036] During use, connect multiple drag chain sections 1 together through the rotating shaft 2. Open the connecting plate 7, and the wire pipe can be fixed between the two movable partitions 13. Multiple movable partitions 13 classify and fix multiple main wire pipes. During the process of guiding and protecting the wire pipe by the drag chain section 1, the stress generated by the force on the drag chain section 1 is dispersed through the strengthening ribs 104 and support ribs 105 on the surface of the chain plate 101. When the drag chain is impacted, the impact force is absorbed and dispersed.

[0037] In summary, by arranging the strengthening ribs 104 and support ribs 105 at the stress-bearing parts of the chain plate 101 of the drag chain, the strength and rigidity of the drag chain are enhanced to disperse the stress generated by the force, reduce the stress concentration at the joints, enhance the stability of the drag chain, and the strengthening ribs can also absorb and disperse the impact force, making the drag chain not easily deformed or damaged when being impacted, thereby prolonging the service life of the drag chain and improving the use effect.
