The input end of the driving device is exposed outside the housing. The input end of the speed increasing device is connected to the output end of the driving device, and the output end of the speed increasing device is connected to the input end of the generator. The output end of the generator is connected to a USB interface. The driving device is used for converting rectilinear motion into rotation motion. The hand-held power generating dumbbell serving as the fitness apparatus can convert the gripping power of hands into electric energy, can charge digital equipment when being used for body-building, is convenient to carry, and is economical and practical.

Description

technical field [0001] The invention relates to a fitness equipment, in particular to a dumbbell. Background technique [0002] Existing low-power household appliances, children's electric toys and other products generally use dry batteries as their energy sources. The disadvantage is that the batteries need to be replaced frequently, and these household appliances and children's electric toys must be replaced when they are not used for a period of time. Take it out in time. If you forget to take it out due to negligence, it will not only cause the battery to fail, but also cause the battery to leak, which will pollute the environment and even damage the electrical appliances. For this reason, the user is very troubled, but helpless. [0003] The object of the present invention is to consider the above problems and provide a fitness equipment that converts the grip force of the human hand into electric energy, which has a simple structure, small size, convenient portability...

Problems solved by technology

[0004] In addition, the existing dumbbells are all solid, and once they are made into shapes, their weight cannot be changed, which cannot meet the fitness requirements of people of all ages.

In order to solve the above problems, Chinese invention patent 2012200599832 has announced "a dumbbell with variable weight", which can adjust the weight of the dumbbell through the counterweight, and it is provided with a prominent thread screw head on the bell head. It affects the overall sense of the dumbbell, and on the other hand, it is not convenient to take and place the counterweight. At the same time, in this solution, the counterweight is block-shaped, and it is not easy to completely fill the cavity of the bell head when placing it.
