Description

Dumbbell subassembly that can dismantle dumbbell piece fast

Technical Field

The utility model relates to a sport equipment technical field, concretely relates to can dismantle dumbbell piece's dumbbell subassembly fast.

Background

Dumbbells are a simple device used for strengthening muscle strength training. Its main material is cast iron, and some of them are covered with a layer of rubber. The muscle training device is used for muscle strength training and muscle compound action training. The dumbbell can be held by a hand of a patient with low muscle strength caused by paralysis, pain, long-term inactivity and the like in exercise, and resistance active exercise can be performed by using the weight of the dumbbell to train the muscle strength. Dumbbells can train a single muscle; if the weight is increased, the coordination of a plurality of muscles is needed, and the training can also be used as a muscle compound action training. An auxiliary equipment for weight lifting and body building exercises. There are both fixed weight and adjustable weight. The dumbbell with the fixed weight: the dumbbell is cast by pig iron, the middle of the dumbbell is an iron bar, and the two ends of the dumbbell are solid balls, so the dumbbell is named because no sound is produced during practice. The weight of the light dumbbell may be 6, 8, 12, 16 pounds, etc. The weight of the heavy dumbbell is 10, 15, 20, 25, 30 kilograms and the like. The dumbbell can be adjusted: the barbell similar to a small barbell is characterized in that round iron sheets with different weights are sleeved at two ends of a short iron rod, the length of each iron sheet is about 40-45 cm, and the weight can be increased or decreased during weight lifting or body building exercises.
