Detailed Description
The technical scheme of the application is further explained in detail with reference to the attached drawings.
Fig. 1 to 3 are schematic diagrams of a chest expander for arms and back, and the technical scheme is explained in detail in the following with reference to the attached drawings.
As shown in fig. 1-3, a chest expander for arms and back comprises a back stretching pad 1, wherein both sides of the back stretching pad 1 are connected with elastic parts 2, and the arms pass through the elastic parts 2 to wear the chest expander on the body.
In the embodiment, a back stretching pad and an elastic component are arranged, the arm penetrates through the elastic component to wear the chest expander on the body for stretching the back, meanwhile, the elastic component is held by two hands, and the back stretching pad is stepped on by feet for stretching the arm.
In the present embodiment, the elastic member 2 is an elastic ring made of an elastic tube. Therefore, the elastic tube is light, good in elastic effect and convenient to carry and use.
In the present embodiment, the elastic ring has an inverted trapezoidal structure suitable for the structure of the human body, and the side length of the elastic ring on the side close to the back stretching pad 1 is smaller than the side length of the elastic ring on the side far from the back stretching pad 1. Therefore, the reverse trapezoidal structure of the human body structure is adopted, the chest expander is suitable for the shoulder structure of a human body, the arm penetrates through the elastic component to wear the chest expander on the body, the back and the shoulder of the human body are attached, and the arm is not uncomfortable to feel.
In the present embodiment, the handle 3 is provided on the side of the elastic ring away from the back tension pad 1. Therefore, the handle is arranged to facilitate the stretching of the handle by the human body.
In this embodiment, the handle 3 is a foam handle sleeved on the elastic tube. Therefore, the material of the foam is adopted, so that the fabric is not easy to slip when being stretched in use and is easy to absorb sweat.
In the present embodiment, the back stretching pad 1 includes a middle support 11 and connecting supports 12 disposed at both sides of the middle support 11, a through hole 121 is disposed at one side of each connecting support 12 close to the elastic member 2, and the elastic member 2 penetrates through the through hole 121. Therefore, by adopting the structure of the middle supporting piece and the connecting supporting pieces arranged on the two sides of the middle supporting piece, the middle supporting piece can be relatively attached to the back of a human body.
In the present embodiment, the middle support 11 includes a rectangular region 111 disposed in the middle and trapezoidal regions 112 disposed on both sides of the rectangular region 111, one side of the trapezoidal region 112 near the rectangular region 111 is a short side, and one side of the trapezoidal region 112 connected to the connecting support 12 is a long side of the trapezoidal region 112. Therefore, the middle rectangular area and the trapezoid areas arranged on the two sides of the rectangular area are adopted, so that the back stretching device is used for the physiological structure of a human body, and the stretching effect of the back is better.
In this embodiment, a soft plastic 13 is sewn into the middle support 11. Therefore, soft plastic is sewn in the middle supporting piece, so that the strength is increased, and the middle supporting piece is not easy to deform.
In the present embodiment, the middle support 11 is made of rubber. The connecting support 12 is made of elastic cloth. Therefore, when the tension device is used, the effect of tension is better, and the strength of the tension which can be borne is higher.
The chest expander for arms and back, simple structure is small and exquisite, and convenient to use, design benefit set up the tensile pad in back and elastic component, and the arm passes elastic component will the chest expander is dressed on one's body for the back is tensile, and two hands have good elastic component simultaneously, step on the tensile pad in back with the foot and can be used to the arm tensile or only two independent arms are tensile, and it is light to use.
