The plate 111 is relatively buckled with the lower annular side plate 121. Specifically, the upper annular side plate 111 includes an upper inner plate 1111 and an upper outer plate 1112, and the lower annular side plate 121 includes a lower inner plate 1211 and a lower outer plate 1212. The upper inner plate 1111 and the lower inner plate 1211 are arranged in a staggered manner, and the lower edge of the upper outer plate 1112 and the upper edge of the lower outer plate 1212 are relatively abutted, so as to ensure the stability of the buckled connection between the upper annular side plate 111 and the lower annular side plate 121. In order to increase the supporting strength of the lower annular side plate 121, a plurality of first ribs 1213 are arranged between the lower inner plate 1211 and the lower outer plate 1212.

[0043] The support frame includes an upper metal support plate 13 and six first support columns 122. The six first support columns 122 are supported between the upper metal support plate 13 and the top of the bottom plate 12. A recessed portion 112 for accommodating the upper metal support plate 13 is formed on the top of the top plate 11. The upper metal support plate 13 is embedded in the recessed portion 112 and is locked and fixed with the top plate 11 by bolts. The recessed portion 112 can facilitate the positioning and installation of the upper metal support plate 13. The shape of the upper metal support plate 13 is adapted to the top surface of the top plate 11 and is slightly smaller than the top surface of the top plate 11, which can improve the supporting strength of the product. The top surface of the upper metal support plate 13 is provided with an anti-skid pad 14, which is made of rubber or silicone. The anti-skid pad 14 can prevent users from slipping when using the product, thereby increasing the safety of the product. The specific top plate, bottom plate and upper metal support plate 13 are rectangular structures.

[0044] The two resistance mechanisms 2 are distributed on the left and right sides of the bottom of the upper metal support plate 13, and a clearance hole for avoiding the resistance mechanism 2 and the first support column 122 is opened on the top plate 11. One end of the tension belt 3 is connected to the resistance mechanism 2, and the other end extends out of the shell 1. Three first support columns 122 are distributed on the periphery of one resistance mechanism, and the other three first support columns 122 are distributed on the periphery of the other resistance mechanism. This can increase the installation stability of the resistance mechanism 2.

[0045] The bottom plate 12 and the upper metal support plate 13 are arranged relative to each other with an interval, and a plurality of first support columns 122 are arranged between the upper metal support plate 13 and the bottom plate 12. The first support columns 122 are fixedly arranged on the bottom plate 12. The first support columns 122 are metal tubular structures. The upper ends of the first support columns 122 are welded to the bottom of the upper metal support plate. The plurality of first support columns 122 are distributed below the area of ​​the upper metal support plate 13 for stepping on by both feet to ensure the supporting strength of the stepping area. A positioning groove 127 for positioning the lower end of the first support column 122 is provided on the bottom plate 12.

[0046] A certain space is formed between the bottom plate 12 and the upper metal support plate 13 by spacing, and is used to install the resistance mechanism 2 and the first support column 122.

The plurality of second support columns are spaced apart along the periphery of the top plate 11 and the bottom plate 12 and are located below the upper metal support plate 13. Because the first support column 122 is provided on the pedal area for support, arranging the second support columns on the periphery can improve the support strength of the shell 1 to a greater extent. When the user steps on the upper metal support plate 13, the top plate 11 will also bear the downward gravity of the user. The second support columns can share the gravity borne by the top plate 11, thereby improving the support strength between the top plate 11 and the bottom plate 12.

The lower section 123 is connected to the lower inner plate 1211 by a plurality of first ribs 1213 and second ribs 126 to enhance the stability of the lower section 123. A positioning groove 1231 is formed at the upper end of the lower section 123 to receive the lower end of the upper section 114. The positioning groove 1231 facilitates the positioning and installation between the upper section 114 and the lower section 123. A bolt through hole 1141 is provided inside the upper section 114 by a bridging manner. A bolt hole 1232 is provided inside the lower section 123 by a bridging manner. The bolt passes through the bolt through hole 1141 and is threadedly connected to the bolt hole 1232. The top plate 11 and the bottom plate 12 of the shell 1 are fixedly connected by fixing the upper section 114 and the lower section 123. The position where the bottom plate 12 is connected to the first support column 122 and the lower section 123 is sunken downward and in contact with the ground, so that the first support column 122 and the lower section 123 are subjected to gravity and move downward through the bottom plate 12 to contact the ground, thereby preventing the bottom plate 12 from being deformed due to excessive gravity.

[0048] The resistance mechanism 2 includes a mounting seat 21, a magnetic powder brake 22, an elastic member and a storage wheel 24. The mounting seat 21 is made of metal.

The outer end 231 of the mainspring 23 is fixedly connected to the mainspring chamber 242, and the inner end 252 of the mainspring 23 is fixedly connected to the fixed shaft 25. When the tension band 3 is pulled out, the tension band 3 drives the winding wheel 24 to rotate, and the winding wheel 24 drives the mainspring 23 to rotate. Because the fixed shaft 25 cannot rotate, an elastic force is generated when the mainspring 23 rotates, and the elastic force causes the mainspring 23 to rotate, and the winding wheel 24 is driven to rotate by the mainspring 23, so that the tension band 3 is rolled back into the annular groove 243.

[0049] A handle 31 is provided at one end of the tension band 3 pulled out of the shell 1, and the handle 31 is composed of a hollow cylinder 311 and a foam pad 312 covering the outer circumferential surface of the hollow cylinder 311.

The storage wheel 64 is connected to the upper metal support plate 84 by a one-way bearing 611. 45 is unidirectionally rotatably arranged on the output shaft 622, and a bearing hole 646 for installing a one-way bearing 645 is arranged on the storage wheel 64. One end of the tension belt 7 is connected to the storage wheel 64 and the other end is output outside the housing 5. When the tension belt 7 is pulled out, the storage wheel 64 rotates forwardly to drive the output shaft 622 of the magnetic powder brake 62 to rotate through the one-way bearing 645, and the elastic member drives the storage wheel 64 to reverse and store the tension belt 7 on the storage wheel 64. The storage wheel 64 includes an integrally formed wheel portion 641 and a spring chamber 642. The outer peripheral surface of the wheel portion 641 is formed with an annular groove 643 for storing the tension belt 7.

The shaft 65 is inserted into the limiting portion 5241 through the limiting hole 651 so that the fixed shaft 65 is fixed and cannot rotate. The outer end 631 of the spring 63 is fixedly connected to the spring chamber 642, and the inner end 652 of the spring 63 is fixedly connected to the fixed shaft 65. When the tension band 7 is pulled out, the tension band 7 drives the winding wheel 64 to rotate, and the winding wheel 64 drives the spring 63 to rotate. Because the fixed shaft 65 cannot rotate, an elastic force is generated when the spring 63 rotates, and the elastic force causes the spring 63 to rotate, and the winding wheel 64 is driven to rotate by the spring 63, so that the tension band 7 is rolled back into the annular groove 643.

[0059] A handle 71 is provided at one end of the tension band 7 pulled out of the shell 5, and the handle 71 is composed of a hollow cylinder 711 and a foam pad covering the outer circumferential surface of the hollow cylinder 711.
