Description

Technical Field

[0001] The utility model relates to the technical field of drag chain cables, in particular to a drag chain cable bending test device. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire used to transmit electricity or information from one place to another. In situations where equipment units need to move back and forth, in order to prevent the cables from getting entangled, worn, pulled off, hung, and scattered, the cables are often placed in cable drag chains to protect the cables. The cables can also move back and forth with the drag chain. This highly flexible special cable that can move back and forth with the drag chain and is not easily worn is called a drag chain cable, also commonly known as a towing cable or a tank chain cable.

[0003] Before the drag chain cable leaves the factory, it needs to be subjected to a bending test to determine whether the product is qualified. However, most of the existing bending test devices can only bend the drag chain cable at a fixed angle, resulting in the test data being too single and unable to meet the requirements for the drag chain cable during use. Therefore, further improvements are needed on this basis. Utility Model Content

[0038] When it is necessary to perform a bending test on the drag chain cable, one end of the drag chain cable is fixed to the middle of the fixed clamp block 3, and the other end passes through the two long rods 10.
