A counterweight device for weight training

Abstract

The invention belongs to the technical field of sporting goods and relates to a counterweight device for weightlifting training. The utility model solves the technical problems of the existing counterweight device such as inconvenient addition and removal of the counterweight, difficulty in disassembly and assembly, and the like. The counterweight device used for weightlifting training includes a barrel body 1, the upper end of the barrel body 1 has an opening 1, the barrel body 1 is provided with a counterweight liquid, the barrel body 1 is provided with an inverted barrel body 2, and the barrel body 2 has an opening 1. There is an opening 2 at the lower end, and several vertical partitions are arranged inside the barrel body 2, and the partition board divides the barrel body 2 into several chambers, and the lower end of each chamber is connected to the opening 2; the upper end of each chamber has a through-hole Through the air flow channel that the upper end of the barrel body two communicates with the outside world, each air flow channel is also provided with a control valve, and the upper end of the barrel body two has a pull cord. The device has a simple structure and is convenient to disassemble and assemble, and through the effect of atmospheric pressure on the barrel body 2 and the opening and closing of the control valve, the counterweight can be quickly increased or decreased.

Description

technical field

[0001] The invention belongs to the technical field of sporting goods and relates to a counterweight device for weightlifting training. Background technique

[0002] Fitness equipment is often divided into two categories: single-function and comprehensive multi-function according to the number of training functions. Commonly used are rowing machines, fitness bikes, walking machines, treadmills, waist shaping machines, etc. The development of China's fitness equipment industry began in 20 At the end of the 1980s, with China's accession to the WTO and the success of Beijing's Olympic bid, favorable conditions and development opportunities were provided for the development of the fitness equipment industry. The continuous expansion of the fitness team brought strong business opportunities for fitness equipment manufacturers. With the continuous improvement of fitness, fitness is more and more favored by people, which can have a positive impact on human health, e...

Embodiment 1

[0022] Such as figure 1 with figure 2 As shown, the counterweight device used for weightlifting training comprises a barrel body-1, the upper end of the barrel body-1 has an opening-2, the barrel body-1 is provided with a counterweight liquid 3, and the barrel body-1 is provided with an undercut The barrel body 2 4, the lower end of the barrel body 2 4 has an opening 2 5, the barrel body 2 4 is provided with some vertical partitions 6 and the partition plate 6 separates the barrel body 2 4 into several chambers 7, each The lower end of the chamber 7 is connected to the opening 2 5; the upper end of each chamber 7 has an air flow channel 8 passing through the upper end of the barrel body 2 4 to communicate with the outside world, and each air flow channel 8 is also provided with a control valve 9, the barrel body The upper end of two 4 has stay cord 10. The weight fluid 3 is water; the control valve 9 has a valve knob 13 . Counterweight device has two groups, and two barrel...

Embodiment 2

[0025] The structure of this embodiment is substantially the same as that of the first embodiment, except that the counterweight fluid 3 is a magnetic fluid, and each chamber 7 in the second barrel 4 is provided with an electromagnet. During the lifting process of the barrel body 2 4, the electromagnet attracts the magnetic fluid to increase the weight of the counterweight device.
