Description
Technical Field
[0001] The utility model relates to the technical field of power cable structures, in particular to a power cable structure capable of preventing excessive twisting. Background Art
[0002] Power cables are very common equipment in the prior art. Power cables used in some industrial environments are made thicker due to protection requirements, that is, the outer side has a protective layer of sufficient strength. However, this reduces the degree of bendability and twisting of the power cables. In order to prevent the power cables from moving back and forth during industrial use and causing excessive bending, some protective mechanisms are needed for protection.
[0003] In the prior art, cable drag chains are used to protect power cables to prevent excessive bending and twisting of the power cables. However, in such cable drag chains, in addition to power cables, other cables such as control cables are often installed. That is to say, there is more than one wire in such cable drag chains. In the prior art, such cable drag chains do not have a code wire structure, which easily leads to entanglement of cables inside the cable drag chains. Therefore, in order to address this problem, there is a need for an improved power cable structure that prevents excessive twisting. Utility Model Content
[0004] The utility model aims to provide a power cable structure which can prevent excessive twisting, so as to solve the problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power cable structure for preventing excessive twisting, including a protective drag chain, the protective drag chain including a standard section and a code line section, the standard section including a first shell, a first connecting hole, and a first connecting block, a first connecting hole is opened on one side of the surface of the first shell, and a first connecting block is fixedly arranged on one side of the surface of the first shell, the code line section includes a second shell, a second connecting hole, a second connecting block, a first code line seat, and a second code line seat, a second connecting hole is opened on one side of the surface of the second shell, and a first connecting block is fixedly arranged on one side of the surface of the second shell, a first code line seat is fixedly arranged inside the second shell, and a plurality of second code line seats are evenly arranged on the upper end of the second code line seat.
[0006] Preferably, a plurality of grooves are evenly arranged on the outer surfaces of the first and second code wire seats. By splicing the grooves on the outer surfaces of the first and second code wire seats together, a cable arrangement hole can be formed, thereby playing the role of fixing the cables; so that multiple cables inside the protection drag chain can exist independently without the possibility of entanglement.
[0007] Preferably, a slot is provided on the upper end of the outer surface of the second code wire seat and the first code wire seat, and a pin is fixedly provided at the lower end of the second code wire seat. The second code wire seat can be separated from the first code wire seat. The purpose is to make it more convenient to fix the cable. If the first code wire seat and the second code wire seat are fixed from the beginning, when you want to fix the cable, you can only accurately pass the cable through the through hole through the entire protective drag chain. The first code wire seat and the second code wire seat are separated, so you can pass the wire through at will, and then fix the wire after the entire wire is passed through, which will be much more convenient for the threading part.
[0008] Preferably, a fixing plate is fixedly provided on the upper end of the second code line seat at the uppermost end, and threaded holes are provided on the fixing plate and the outer surface of the second shell. A locking screw is provided on the upper end of the fixing plate, and the second code line seat at the uppermost end can be fixed to the second shell through the threaded hole and the locking screw; thereby, multiple second code line seats can be fixed inside the second shell.
[0009] Preferably, the standard section and the yard line section are hingedly connected to each other at intervals through the first connecting hole, the first connecting block and the second connecting hole, and the second connecting block; in this way, the standard section and the yard line section can be connected into a protective drag chain; and the yard line section and the standard section should be connected at intervals, with about five standard sections set, and then one standard section set; in this way, all the cables inside the drag chain can be protected; and in actual use, the specific number of standard sections to design a yard line section can be assembled according to needs.
[0010] Preferably, a limit block is fixedly provided on one side of the surface of the first shell and the second shell, and the limit block can limit the rotation range of the first shell and the second shell; thereby avoiding excessive bending of the cable inside the protective drag chain.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The utility model can independently fix the wires passing through the protective drag chain in intervals and layers inside the protective drag chain; in this way, the device can protect the cables, prevent the cables from excessive bending, and prevent multiple cables from getting entangled inside the protective drag chain.
[0013] 2. Due to the split design of the second code wire seat of the utility model, the device is more convenient when fixing cables. The cables can be passed through at will first, and then the cables can be fixed. This is convenient to operate, and there is no need to align the holes for threading at the beginning. It is also more convenient to fix some cables with plugs installed on both ends. BRIEF DESCRIPTION OF THE DRAWINGS
