AI Technical Summary

Technical Problem

The vibrations and noise generated by existing dumbbells during use can be inconvenient in noise-sensitive environments, especially in home gyms, and the installation and removal of dumbbell plates can also generate noise.

Method used

It adopts a combination design of anti-collision ring, shock absorption component, shock absorption pipeline and spring, and uses the flexibility of rubber material and the absorption force of telescopic rod to reduce the collision noise between dumbbell plates, and absorbs vibration when the shock absorption component contacts the ground to reduce noise and vibration.

Benefits of technology

It effectively reduces noise and vibration during dumbbell use, improves quietness, and avoids rolling noise when the dumbbell plates land, making it suitable for home fitness environments.

Abstract

This utility model relates to the field of dumbbell technology and discloses a dumbbell with shock absorption and noise reduction. Both ends of the dumbbell bar are fixedly connected to mounting heads. Dumbbell plates are movably sleeved on the surface of each mounting head. A fixing nut is threadedly fixed to the surface of the mounting head, and the dumbbell plates are fixedly sleeved on the surface of the mounting head by the fixing nut. Anti-collision rings are fixedly connected to both sides of the dumbbell plate surface. Regularly arranged shock-absorbing components are formed around the perimeter of the dumbbell plate surface. The anti-collision rings and shock-absorbing components are all made of rubber. Shock-absorbing pipes are fixedly sleeved inside the shock-absorbing components on each dumbbell plate. Telescopic rods are fixedly connected to both sides of the shock-absorbing components near the surface of the dumbbell plate, and the telescopic rods are movably sleeved inside the shock-absorbing pipes. The anti-collision rings help to isolate the dumbbell plates when multiple dumbbell plates are mounted on the surface of the mounting head, preventing noise caused by collisions between the dumbbell plates.
