Portable two-way force application arm strength device and manufacturing method and using method thereof

Abstract

The invention discloses a portable two-way force application arm strength device and a manufacturing method and a using method thereof. The portable two-way force application arm strength device comprises a spiral spring, handles arranged near the spiral spring and buffer mechanisms located in the handle, the spiral spring is of a hollow cavity structure, and a non-Newtonian liquid is injected into a cavity of the spiral spring; and the handles are embedded into the two ends of the spiral spring respectively, openings are formed in the two ends of the spiral spring respectively, the openings are located in the handles, the two handles are fixedly connected with the two ends of the spiral spring, and the buffer mechanisms are arranged in the two handles respectively. The buffer mechanism comprises a partition plate and a buffer plate, the partition plate divides the handle into a storage cavity and a backflow cavity along the axis of the spiral spring, the buffer plate comprises a storage plate and a backflow plate, the storage plate is located on one side of the storage cavity in the handle, and the backflow plate is located on one side of the backflow cavity in the handle. Bidirectional exercise of muscles on the inner side and the outer side of the arm can be achieved, deformation can be kept, and injuries caused by springback are avoided.

Description

technical field [0001] The invention relates to a fitness equipment, in particular to a portable two-way force-applying arm strength device and a manufacturing method and a using method thereof. Background technique [0002] The arm strength machine, also known as the grip stick, is used to exercise the arm muscles, mainly to exercise the arm strength and chest muscles, to assist in the exercise of the wrist strength, to exercise the arm muscles, and the forearm wrist flexors. The positive U shape of the arm strength machine can train the triceps, pectoralis major, and middle deltoid muscle; the reverse U shape of the arm strength machine can train the biceps brachii, pectoralis major, middle deltoid muscle, and latissimus dorsi. [0003] Arm strength exercise method: 1. Bend both arms, bend the spring forcefully behind the neck; 2. Move the arms forward, bend the spring upwards, and then relax; 3. Move the arms closer to the chest, bend the spring, then straighten it, slowl...

AI Technical Summary

Problems solved by technology

[0004] During the use of conventional arm strength devices, no matter whether it is a forward U-bend or a reverse U-bend, there is great danger. Incidents of arm strength devices often dropping hands and injuring oneself, and during the use of the arm strength device, it is always necessary to keep the arm facing The chest is closed, and the back muscles cannot be effectively exercised, and the strength training level of the conventional arm strength machine depends entirely on the spring material, and the training strength level cannot be adjusted for the arm strength machine with a fixed material. After a period of training, it is necessary to purchase a new one. High-level arm strength machine, the cost of exercise is higher
