Description

Technical Field

[0001] The invention relates to the technical field of dumbbells, in particular to a dumbbell which can be rotatably adjusted and has an anti-slip protective cover at the end. Background Art

[0002] Dumbbells are an auxiliary equipment for weightlifting and fitness exercises. They are smaller than barbells. Light dumbbells have weights of 1, 2, 3, 5, 8 and 12 pounds (1 pound = 0.4536 kilograms), and heavy dumbbells have weights of 10, 15 and 30 kilograms. Because they are silent during exercise, they are named dumbbells. Dumbbells are a simple equipment used to enhance muscle strength training. Its main material is cast iron, and some are covered with a layer of rubber. It is used for muscle strength training and muscle compound movement training. Patients with low muscle strength due to motor paralysis, pain, long-term inactivity, etc. can hold dumbbells and use the weight of dumbbells to perform active resistance exercises to train muscle strength.

[0003] Nowadays, the use of dumbbells has become more and more common in the fitness industry. However, in the process of fitness, dumbbells can only be trained through push-ups to enhance muscle strength, resulting in a relatively single training method and the effect of use cannot be maximized.

[0015] Through the above technical solution, when installing the adjustment component, the installation sleeve is connected to the left end of the dumbbell rod. At this time, the positioning hole and the fastening bolt are in a parallel state until the left end of the dumbbell rod can no longer go deeper. Then, the regulating valve is rotated to drive the fastening bolt to rotate, thereby engaging with the inner side of the positioning hole, so that the installation sleeve is fixed to the outer side of the dumbbell rod.

[0016] Preferably, a connecting hole is respectively provided on the front side and the rear side of the mounting sleeve, and the size and shape of the connecting hole match the connecting bolts between the mounting sleeve and the connecting seat.

[0017] Through the above technical solution, after installing the adjustment component, the nut at one end of the connecting bolt is rotated to perform rotational adjustment between the installation sleeve and the connecting seat, thereby changing the training method.
