Example Embodiment
[0034] Example one
[0035] By attaching Figure 2-5 It can be seen that the present invention relates to a resistance unit with a resistance band combined structure, which includes a support rod 203, a resistance band 201, a whole insulating tube 202 and a conductor 212, and the support rod 203, the resistance band 201 and the whole insulating tube 202 are combined. The two ends of the resistance band 202 are isolated and positioned through the entire insulating tube 202 for isolation and positioning.
[0036] The support rod 203 is a cylindrical metal rod commonly called a tie rod. There are two support rods 203, namely the first support rod 205 and the second support rod 206; the first support rod 205 and the second support rod 206 The support rods 206 are respectively located at the ends 204 of the upper and lower ends of the resistance band 201, and pass through the central hole 207 on the entire insulating tube 202, and both ends extend out of the entire insulating tube 202, ...
Example Embodiment
[0042] Example two
[0043] The principle of the second embodiment is the same as that of the first embodiment, except that the structure of the insulating tube is slightly different. The different parts are as attached Figure 6-8 Shown is a resistance unit with a combined structure of resistance bands, including a support rod 303, a resistance band 301, and an integral insulating tube 302. The support rod 303, the resistance band 301, and the integral insulating tube 302 are combined to form a resistance unit. The characteristic is The isolation and positioning of the two ends of the resistance band 301 are performed by a tooth-shaped integral insulating tube 302 for isolation and positioning.
[0044] It’s just that the integral insulating tube 302 is an integral composite polymer insulating tube made of composite polymer materials, and the cross-sectional shape of the integral composite polymer insulating tube is a multi-tooth shape, which is convenient for the integral composit...
Example Embodiment
[0048] Example three
[0049] The principle of the third embodiment is the same as that of the second embodiment. The whole composite polymer insulation tube is used, but the direction of the "C"-shaped opening on the resistance band is slightly different, and the direction of the offset opening is perpendicular to each other. One end of the opening is on the top of the resistance band, and the other end is on the side of the resistance band, making the "C"-shaped opening of the overall composite polymer insulation tube more flexible and changeable when it is clamped into the resistance band.
[0050] The cross section of the integral composite polymer insulation tube can be of various cross-sectional shapes, and can be circular, elliptical, arbitrary polygonal or multi-tooth structure (such as attached Picture 9 Shown), and there are card slots on the outer surface of round, arbitrary polygon or multi-tooth.
