Description

Technical Field

[0001] The utility model relates to the technical field of joint bearings, in particular to an engineering plastic joint bearing for medical food. Background Art

[0002] Spherical bearing is a mechanical device used to connect two parts and allow them to rotate or move in different directions. It usually consists of an inner ring, an outer ring, rolling elements and a retainer. Spherical bearings are mainly used to connect rotating shafts and mechanical parts so that they can rotate in different directions while maintaining a certain axial and radial clearance. This design makes spherical bearings suitable for applications that need to withstand large angular offsets and axial displacements, and can be used in the medical food field;

[0003] After searching, the applicant found that a Chinese patent disclosed "a kind of spherical bearing", and its publication (announcement) number is "CN216589550U". This patent mainly involves moving the movable tube to make the connecting rod at an appropriate length when the length of the connecting rod needs to be adjusted, and then fixing the movable tube through a fixing mechanism, so that the length of the connecting rod can be adjusted, thereby facilitating the installation of the spherical bearing. However, in the original application document specification, metal powder may fall off during the movement, which will cause food safety problems. For this reason, we propose an engineering plastic spherical bearing for medical food. Utility Model Content
