Embodiment 1
[0037] Embodiment 1: A noise reduction towline
[0038] See attached Figure 1-5 , in this embodiment, including several chain links 1 connected end to end, between any two adjacent chain links 1, the tail of the chain plate 2 of the previous chain link 1 and the corresponding chain plate 2 of the next chain link 1 The first part realizes the rotation connection through the hole 7 and the hole axis of the shaft 8 , and in the chain link 1 , the chain plates 2 on both sides are connected through the cross bar 20 . A rotation limiting mechanism is provided at the position of the rotation connection to control the rotation angle and orientation between two adjacent chain links 1 .
[0039] The rotation limiting mechanism includes two sets of rotation limiting structures, which reflect that the rotation angles and azimuths between two adjacent chain links 1 are the same, so as to jointly share the The load and impact caused by the rotation limit between section 1.

The invention relates to a noise-reduction drag chain. The noise-reduction drag chain is formed by connecting a plurality of chain links end to end, and a rotation limiting mechanism is arranged between each former chain link and the next chain link. Each rotation limiting mechanism comprises a limiting convex block of one chain link and a limiting notch of the next chain link, wherein first buffering holes are formed beside convex block impact surfaces of the limiting convex block, and the first buffering holes are formed in the limiting convex blocks to form first elastic edges. Each rotation limiting mechanism further comprises a circular-arc convex portion of each former chain link and a circular-arc concave portion of the next chain link, wherein convex portion impact surfaces are arranged at the joints of the upper end surface, the lower end surface and circular-arc surfaces at the two ends of each chain link; second buffering holes are formed beside the convex portion impact surfaces; and the second buffering holes are formed in the chain links to form second elastic edges. The noise-reduction drag chain is simple in structure and ingenious in concept. The buffering holes are formed beside the impact surfaces of the rotation limiting mechanisms. When the adjacent chain links rotate and impact each other, the buffering holes play a role in buffering mutual impact between every two corresponding chain plates, and therefore noise is lowered, and the purpose of silencing of the drain chain is effectively realized.
Description
technical field [0001] The invention belongs to the field of towlines, in particular to a functional towline for guiding and protecting flexible objects such as hoses and cables, in particular to a towline suitable for heavy-duty environments with a mute effect (it can also be used for low-speed heavy load or low speed light load environment). Background technique [0002] Drag chain is a kind of functional chain used in reciprocating motion occasions to pull and protect its built-in cables, hoses and other objects. Drag chains are generally used in technical fields such as CNC machine tools, electronic equipment, stone machinery, glass machinery, door and window machinery, injection molding machines, manipulators, lifting and transportation equipment, automated warehouses, and robots. [0003] The drag chain is usually formed by connecting multiple chain links through shafts, each chain link has two chain plates, and each chain plate is provided with two holes for installi...
