AI Technical Summary

Technical Problem

The counterweights on existing dumbbells or kettlebells are prone to loosening or falling off due to accidental contact or improper operation, affecting safety and stability during use.

Method used

Design a counterweight component that uses an adapter and locking mechanism. The component is detachably connected via an operating mechanism in the operating hole. The use of a threaded structure and locking groove ensures that the counterweight will not loosen due to accidental contact during use. The locking mechanism is hidden inside the hole, improving safety and stability.

Benefits of technology

It achieves a safe and reliable connection of the counterweight, avoiding loosening or falling due to accidental contact, improving the safety and stability of dumbbells and kettlebells, and is simple in structure and easy to operate.

Abstract

A counterweight, dumbbell, and kettlebell are disclosed. The counterweight includes a body, characterized in that: one end of the body has a protruding adapter, and the other end of the body has an operating hole opposite to the adapter. The adapter has a locking member whose front end can extend or retract from the side of the adapter. The operating hole has an operating mechanism for driving the locking member to extend and retract. The adapter has a first connecting structure for detachably connecting to the hole by relative rotation. The hole has a locking groove for the front end of the locking member to be inserted to restrict the rotation of the adapter relative to the hole. In the above scheme, the operating mechanism is located in the operating hole, so that the counterweight will not be loosened or fall off due to accidental contact with the operating mechanism during the use of the dumbbell or kettlebell. In addition, the locking member is located in the adapter and cooperates with the locking groove in the hole to restrict the rotation of the adapter relative to the hole. That is, after the counterweight is installed, the locking member is hidden in the hole and cannot be touched, thus further improving the safety and stability of the counterweight installation.
