Micro drag chain

Abstract

The invention discloses a micro drag chain. The micro drag chain comprises a group of base bodies which are hinged with each other and are connected into an integer, and end bodies connected to the two ends of each base body, wherein each base body at least comprises a bottom plate as well as a fixed assembly and a connecting assembly which are arranged at the same side of the bottom plate, and the fixed assembly is matched with the connecting assembly on the adjacent base body to form an accommodating space capable of accommodating a pipeline; and a first limiting device is arranged on each fixed assembly, a second limiting device is arranged on each connecting assembly, and the first limiting device is matched with the second limiting device to complete limiting on an angle of deflectionof the adjacent base body. The micro drag chain has the beneficial effects that: the micro drag chain can be relatively fixed in bending angle in a working process, and prevents unnecessary trouble.Meanwhile, each fixed assembly is matched with each connecting assembly to form a space, periphery of which is sealed, so that a pipeline in the space is guaranteed to not drop, and therefore, the micro drag chain is delicate in structure and is convenient to manufacture.

Description

technical field [0001] The invention relates to a pipeline guiding device, which belongs to the technical field of industrial manufacturing equipment. Background technique [0002] In the current production process, cables, water pipes or hydraulic pipes are generally used. For example, in CNC machining centers, the signal wires, hydraulic pipes, cables, and cooling water pipes set on the operating arm will follow the movement of the operating arm relative to the CNC body. move. If there is no line guide, it is easily damaged by friction. Therefore, a flexible pipe is currently used, and its inner cavity is used as the fixing and guiding of the pipeline. However, the guide hose will inevitably be bent or twisted during use, resulting in the possibility of failure of the pipeline inside it. [0003] Therefore, drag chains are currently used as pipeline guiding devices. However, the structure of each base of the towline to accommodate the pipeline is unreasonable, so that ...

Problems solved by technology

However, the structure of each base of the towline to accommodate the pipeline is unreasonable, so that the pipelines in the towline often fall, and because the towline has been in use, a certain base of the towline will be damaged and needs to be replaced, but the existing It is very inconvenient to disassemble the towline, so it is imminent to design a micro towline with reasonable structure
