Dumbbell bar matched with various kinds of bottlenecks

Abstract

The invention discloses a dumbbell bar matched with various kinds of bottlenecks, and relates to the field of fitness equipment. The dumbbell bar comprises a dumbbell bar body; connecting rods are arranged at the two ends of the dumbbell bar body respectively; the axis of the dumbbell bar body and the axes of the connecting rods are coincident, and an anti-skidding device is arranged on the outerside of the dumbbell bar body; a blind hole is formed in the end face, not connected with the dumbbell bar body, of each connecting rod, the axes of the blind holes and the axes of the connecting rodsare coincident, and threads are arranged on the inner lateral sides of the blind holes; the blind holes are in step shapes, and a limiting stop ring is arranged on each step face; a gasket is matchedbetween the outer surface of each limiting stop ring and the inner surface of the corresponding blind hole. According to the dumbbell bar, as the connecting rods are installed at the two ends of thedumbbell bar body, mineral spring water bottles with different neck diameters are matched with the step-shaped blind holes in the connecting rods, a user can replace different types of mineral springwater bottles as required, the weight of a dumbbell can be adjusted, the production cost is reduced, and the fitness effect is improved.

AI Technical Summary

Benefits of technology

This technology allows for easy replacement or customization by adding connections between two end points on each side of a dumbbell-bar with stepable blind hole plates. Users have access through these connection locations instead of having to purchase multiple versions of an existing one due to differences in how they require them. By doing this, it saves money while still providing effective performance without requiring more than what was necessary when purchasing older products.

Problems solved by technology

The technical problem addressed by this patented technology relating to exercise machines that include both heavyweight and lightweight features has been finding ways for users to change their weights more conveniently without having to replace or remove multiple plate configurations each time they want it on an occasional basis due to its high cost compared to regular purchasing options available online.
