Dumbbell capable of rapidly adjusting self weight

Abstract

The invention relates to a dumbbell capable of rapidly adjusting self weight. The dumbbell comprises a handle, a storage battery, a first switch, a second switch, fixing plates, multi-stage electric telescopic rods, first fixing mechanisms, second fixing mechanisms, dumbbell plate devices and heat radiating mechanisms. The storage battery is arranged in the interior of the handle and the left endof the handle is equipped with the first switch. The middle positions of the fixing plates are fixed with the multi-stage electric telescopic rods. The first fixing mechanisms are arranged onto the fixing plates. Additionally, lower surfaces of the first fixing mechanisms are provided with the second fixing mechanisms. The dumbbell plate devices are arranged between the second fixing mechanisms. The heat radiating mechanisms are installed on the handle. Because of the storage battery, switches and rotary devices, the dumbbell plate devices are controlled to be fixed through the switches. Therefore, dumbbell weight can be quickly adjusted. There is no need for a user to rotatably fix the dumbbell plate devices to a dumbbell connecting rod through screw threads.

Description

technical field [0001] The invention relates to the field of dumbbell related equipment, in particular to a dumbbell capable of quickly adjusting its own weight. Background technique [0002] Dumbbell is a simple equipment used to enhance muscle strength training. Its main material is cast iron, and some are covered with a layer of rubber. Its use is for muscle strength training and muscle compound action training. Patients with low muscle strength due to motor paralysis, pain, long-term inactivity, etc., can use the weight of the dumbbell to perform active resistance exercises and train muscle strength by holding a dumbbell. [0003] In actual use, the weight of the dumbbell is fixed on the connecting rod of the dumbbell by threaded connection, but this method cannot adjust the weight of the dumbbell itself more quickly, and there is generally a button on the handle of the dumbbell Wrapped in a layer of rubber, the user is prone to sweat during the use of the dumbbell.
