Description

Technical Field

[0001] The invention relates to the technical field of rope skipping detection, in particular to a plastic rope skipping tension detection device. Background Art

[0002] Plastic skipping rope is a common type of skipping rope, which is made of light and durable plastic material. Compared with skipping ropes made of other materials, plastic skipping rope has the advantages of light weight, low price and easy to carry, so it is deeply loved by the majority of skipping rope enthusiasts. Plastic skipping rope usually has a certain elasticity, which is determined by the characteristics of plastic materials, so that the skipping rope can have a certain resilience and flexibility during use.

[0003] Existing skipping ropes are mostly subjected to destructive tests to detect their material quality, and tensile testing is one of them. Tensile testing is mostly carried out using an electronic tensile gauge. When the skipping rope is subjected to a certain pulling force, the deformation of the surface of the skipping rope is observed. The method of fixing the skipping rope mostly uses a wire fixing method, in which the two ends of the skipping rope are respectively locked and fixed with wire circles. It is easy to cause the skipping rope to loosen during the tensile testing process, and it is also very inconvenient to fix it. At the same time, the existing skipping rope detection device cannot test the toughness of the skipping rope when it is turned, and the detection capability is relatively single.
