A training device with a composite structure of a portable cushion that can realize multi-directional stretching and stretching

Abstract

The invention provides a training device of a portable cushion composite structure capable of achieving multi-direction stretching motions. The device comprises tread rings and a second rotating wheel; a seat piece is of a round solid structure, four groove cavities of hemihedral structures are formed in the four sides of the bottom surface of the seat piece, hair mats are respectively connected to the insides of the groove cavities through first disc rods, the inside of each groove cavity is connected with three elastic bands through a second disc road, the three elastic bands and the hair mat in each groove cavity are uniformly distributed in ninety degree, and in each groove cavity, the hair mat is located on the front sides of the three elastic bands; the bottom surface of the seat piece is of a horizontal plane structure, a rotary groove of a U-shaped groove structure is formed in the horizontal plane structure, therefore after using, the device can be rotatably recycled, the multi-direction tread rings are arranged on the elastic bands, a user can conveniently and selectively use the device according to the exercise intensity and self-conditions, it shows that the device comprehensively combines a cushion, the elastic bands and a lying mat, and the practicability is higher.

Description

technical field [0001] The invention belongs to the technical field of sports training devices, and more specifically relates to a training device with a composite structure of a portable seat cushion that can realize multi-directional stretching and stretching exercises. Background technique [0002] Stretching exercise is a kind of fitness method. Stretching exercise can make the cooperation between ligaments, muscles and joints more flexible and reduce the possibility of injury. Including active stretching and passive stretching, the so-called active stretching refers to mainly relying on the strength of contracting muscles, rather than other external forces to keep the movement in a specific position. strength. The so-called passive stretching refers to using one's own body weight or equipment to keep the limbs in a certain stretched position. It is a slow, relaxing stretch that can also be expected to reduce nerve and muscle excitability, and is a good way to relax af...
