Description

Technical Field

[0001] The utility model relates to the technical field of hanging ring rubbers, in particular to a hanging ring rubber. Background Art

[0002] As the name suggests, lifting rings are ring-shaped objects used to lift heavy objects. Generally, lifting rings are divided into rubber lifting rings, small lifting rings, large lifting rings, high-temperature resistant lifting rings and other types. Different types of lifting rings have different usage scenarios and requirements. In the lifting industry, steel, alloy and steel rope lifting rings are commonly used.

[0003] The existing lifting ring rubber is easily pulled and deformed when the hoisted objects are subjected to greater pressure. When subjected to stress for a long time, the elasticity of the rubber will be greatly reduced and the life of the rubber will be shortened. In addition, it is difficult to adjust the stress angle of the lifting ring rubber. When subjected to greater force, it will rotate itself, resulting in unstable hoisted objects.
