Title:
TUBE BODY SUPPORT MEMBER, TUBE FOR MAKING ROLLER, ROLLER BODY AND USE OF ROLLER BODY
Document Type and Number:
WIPO Patent Application WO/2021/027461
Kind Code:
A1
Abstract:
A tube body support member (2), a tube for making a roller, a roller body, and use of a roller body. The tube body support member comprises a body (21); an outer edge of the body is connected to a connecting portion (22), and the other end of the connecting portion is connected to a support portion (23); the angle between the support portion and the horizontal plane is an acute angle, and the diameter of the circle surrounded by the outer edge of the support portion is greater than the diameter of the circle surrounded by the outer edge of the connecting portion. When the tube is subjected to elastic deformation (such as bending deformation) due to the use environment, the support portion can adaptively deform along with the increase and decrease of the tube diameter of the tube, so as to support the tube, preventing plastic deformation of the tube caused by repeated elastic deformation, maintaining the factory roundness tolerance of the tube.
