Adjustable torsion device

Abstract

The invention provides an adjustable torsion device which is a convenient physical fitness apparatus suitable for indoor and outdoor exercises and can be used for power and muscle exercises of the arms and wrist parts. The adjustable torsion device comprises shell components of left handles and right handles and an adjustable torsion device. The adjustable torsion device comprises two end covers, a worm, a worm gear, two pairs of bearings, a volute spiral spring and a center shaft. The two ends of the center shaft are supported by a pair of bearings and the middle shaft section portion is fixedly connected with one end of the volute spiral spring; the other end of the volute spiral spring is fixedly connected with a semicircular groove in an inner hole of the worm gear; the worm and the worm gear mesh; the two ends of the worm are supported by a pair of bearings and the worm and the bearings are installed in seat holes of handle shells; the two sides of the worm gear are provided with the two end covers fixedly connected with the worm gear; the outer portions of the worm and the worm gear are wrapped in the shell components of the right handles; right handles are fitted on the two sides of the center shaft in the adjustable torsion device through a pair of bearings; left handles are arranged on the outer sides of the right handles in a sleeving manner and fixedly connected to the two ends of the center shaft, and intersect the right handles.

Description

technical field [0001] An adjustable torque device belongs to the design field of sports fitness equipment. Background technique [0002] The adjustable torquer is a convenient physical fitness equipment suitable for indoor and outdoor exercise, which can exercise the muscles of the arms and wrists, as well as the muscles of the chest and back. There are mainly two types of similar arm strength and wrist strength training equipment on the market at present, and a class is a special device in the combination of large fitness equipment, and a class is a small equipment that utilizes the resulting rebound force when bending a giant spring. The disadvantage of the former is that it has special requirements for the venue and space, and it cannot be moved at will, and it cannot be carried. It is extremely inconvenient for daily exercise; the disadvantage of the latter is that not only the strength is not balanced during the bending process , the intensity cannot be adjusted, only...

Problems solved by technology

The disadvantage of the former is that it has special requirements for the venue and space, and it cannot be moved at will, and it cannot be carried. It is extremely inconvenient for daily exercise; the disadvantage of the latter is that not only the strength is not balanced during the bending process , the intensity cannot be adjusted, and there is only one-way effect during the closing process during exercise, and the rebound force generated by the spring after being bent is easy to get out of control, causing accidental injuries to the exerciser and others around
