This utility model discloses a dust collection device for busbar cutting, comprising: a support member, a magnetic suction member, and a collection assembly; the support member has a through hole, and the support member is sleeved on the busbar through the through hole; the support member has an annular groove surrounding the busbar and opening towards the end of the busbar; the magnetic suction member is installed on the support member located on the back of the annular groove, magnetically attracting dust into the annular groove; the collection assembly is installed below the support member and communicates with the annular groove. This reduces the splashing of iron filings and dust, improves safety, and provides a certain degree of protection for the surrounding environment and personnel. It also reduces the penetration of iron filings and dust deep into the busbar, lowers the difficulty of cleaning, and reduces labor intensity. Furthermore, it prevents splashed iron filings from damaging the busbar, maintaining a good appearance for the busbar, reducing the rate of corrosion caused by impurities, and extending its service life.

This utility model provides a magnetic levitation low-friction dual-hub device suitable for heavy-duty medical equipment, belonging to the technical field of hub devices. This magnetic levitation low-friction dual-hub device for heavy-duty medical equipment includes an outer load-bearing hub, an inner drive hub, radial ceramic bearings, and an axial magnetic levitation module. The outer load-bearing hub is sleeved on the outside of the inner drive hub. The radial ceramic bearings are disposed between the outer load-bearing hub and the inner drive hub, and are connected to the inner wall of the outer load-bearing hub and the outer wall of the inner drive hub, respectively. The axial magnetic levitation module is disposed at the end of the outer load-bearing hub away from the radial ceramic bearings, and is connected to the end of the outer load-bearing hub. This invention solves the problems of high friction coefficient, high movement resistance, heavy operating burden for medical personnel, and difficulty in meeting the frequent movement requirements of traditional heavy-duty medical equipment hub systems.
