the rope skipping connector is provided with a rope threading hole for accommodating connection of the end part of the rope skipping, is of a hemispherical structure, and is provided with a splicing hole at the center of a circle on a circular plane;
the end part of the rope skipping handle is provided with a clamping cavity for accommodating the slewing bearing group;
the connecting shaft comprises a threaded end and a plug-in end; the end part of the rope skipping handle extending out of the plug-in end of the connecting shaft is in plug-in fit with the plug-in hole on the rope skipping connector; a limit nut is arranged at the threaded end of the connecting shaft;
the slewing bearing group comprises a pair of slewing bearing units which are respectively nested on the connecting shaft, a bearing limit check ring is nested on the connecting shaft between the pair of slewing bearing units, and two side surfaces of the bearing limit check ring are clung to the side surfaces of the slewing bearing units; one side surface of the limit nut is clung to the side surface of a slewing bearing unit.
Furthermore, the connecting shaft is of a stepped shaft-shaped structure, and the diameter of the threaded end and the diameter of the inserting end of the connecting shaft are smaller than the diameter of the position where the slewing bearing unit is arranged.
Furthermore, the clamping cavity for accommodating the slewing bearing group at the end part of the rope skipping handle is stepped, and a check ring bulge matched with the edge position of the side surface of the slewing bearing unit is formed.
The utility model has the advantages that:
1) According to the utility model, the end part of the rope skipping handle is provided with the cavity for accommodating the double slewing bearings, the connecting shaft is provided with the bearing limiting retainer ring, and after the slewing bearing units are arranged on the connecting shaft, the end face of each slewing bearing unit is provided with the propping structure.
Drawings
The utility model will be described in further detail with reference to the drawings and the detailed description.
Fig. 1 is a schematic view of a jump rope handle joint installation of the present utility model.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model.
