Arm strength device for sports training

Abstract

The invention belongs to the technical field of physical training, in particular to an arm strength device for physical training, which includes two handles, and a plurality of first extension springs are fixedly connected between the two handles, and the two ends of the first extension springs pass through the fixed ring It is fixedly connected with the handle, and a plurality of first springs are fixedly connected to the inner side wall of the handle and the side close to the first tension spring; push the fixing plate, and slide the insertion rod inside the limit slot to the inside of the chute , so that the insertion rod is inserted into the fixing hole of the first insert or the second insert, and the third spring is used to make the first insert or the second insert have good elasticity, which is used to increase the grip plate, the first spring and Pull between the handles, or slide the fixed block into the interior of the fixed groove, and the through holes of the two coincide with each other, and install the pin so that the first insert and the second insert are integrated, and the third spring on both sides The pulling force of the grip plate is enhanced, which is convenient for users to adjust the strength of the pulling force there, and has a wide application range.

Description

technical field [0001] The invention belongs to the technical field of physical training, and in particular relates to an arm strength device for physical training. Background technique [0002] Sports is a complex social and cultural phenomenon. It takes physical and intellectual activities as the basic means, and according to the laws of human growth and development, skill formation and function improvement, it can promote overall development, improve physical quality and comprehensive education level, enhance physical fitness and It is a conscious, purposeful, and organized social activity that improves athletic ability, lifestyle, and quality of life. Arm strength is a tool for physical training. It is used to exercise arm muscles, mainly arm and chest muscles. Auxiliary exercise wrist strength. [0003] There are following problems in existing technology: [0004] 1. The existing arm strength device for physical training cannot adjust the tensile strength at this plac...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing arm strength device for physical training cannot adjust the tensile strength at this place according to the needs of the user when exercising the wrist and arm strength through the first spring and the grip plate, and the scope of application is small;

[0005] 2. The existing arm strength devices for physical training only realize the purpose of arm strength training through a few first extension springs. It is inconvenient for users to adjust the strength of the arm strength device according to the range of tension they bear, which has certain limitations. sex;

[0006] 3. The existing arm strength device for physical training adds a grip plate and a first spring to expand its functions. The cooperation of the two is convenient for the user to exercise the wrist and arm strength. Because the two are generally fixed with the equipment itself, it is inconvenient for the user. Disassemble according to the needs, so that the weight of the equipment will be increased during the later exercise, which is inconvenient for users to use according to needs
