The user holds and pulls the first hook 2 and the second hook 4, causing the resistance band 1 to extend while resisting the resistance from its elasticity, thus achieving the purpose of exercise and fitness.

[0032] In a preferred embodiment, the winding adjustment mechanism 3 is provided with a suction cup 33 on its outer side, such as Figure 2 As shown, it is used to fix the winding adjustment mechanism 3 to the environment or an object, so as to facilitate the use of the resistance band for exercise.

[0033] like Figures 3-6As shown, the winding adjustment mechanism 3 is composed of a winding adjustment mechanism body 31, a locking button 32, a pressure rod 34, a button spring 39, a guide rail 311, a guide rail 312, a locking piece 35, a pressure plate 36, a locking pressure rod, a pressure rod spring 318, a ratchet wheel 37, a reset spring 321, a winding shaft 38, a first limiting rod 319, and a second limiting rod 320. The locking button 32 is fixedly installed at the front of the winding adjustment mechanism body 31, and a suction cup 33 is fixedly installed at the back. The rear end of the locking button 32 is rotationally connected with the button spring 39, the first guide rail 312, the second guide rail 313, and the locking piece 35 through the pressure rod 34. The locking piece 35 and the pressure plate 36 are fixedly connected with the locking pressure rod. The rear end of the ratchet wheel 37 is fixedly connected with the winding shaft 38 through a bolt. The ratchet wheel 37 is rotationally connected with the reset spring 321. The ratchet teeth of the ratchet wheel 37 are rotationally connected with the locking pressure rod. The first limiting rod 319 and the second limiting rod 320 are fixedly connected with the upper and lower ends of the inner side of the winding adjustment mechanism body 31. The middle part of the outer side of the winding shaft 38 is fixedly connected with the tensioning rope 1. The tensioning rope 1 is in contact with the upper left side of the outer side of the first limiting rod 319 and the lower right side of the outer side of the second limiting rod 320. The tensioning rope 1 is fixedly arranged in the holes on the two sides of the body 31. As a preferred embodiment, the holes are square holes.

[0034] The button spring 39 and the pressure rod spring 318 are compression springs, which are used to reset the locking button 32 or the locking pressure rod after moving inward. The reset spring 321 is a torsion spring, which is used to collect the tensioning rope 1 after unfolding.

[0035] In this embodiment, the guide rail sleeve 310 is provided with the first guide rail 311 and the second guide rail 312. The length of the first guide rail 311 is less than that of the second guide rail 312. The end faces of the first guide rail 311 and the second guide rail 312 are bevels. The end face of the locking piece 35 is matched with the end faces of the first guide rail 311 and the second guide rail 312. The end face of the pressure rod 34 is matched with the inner end face of the locking piece 35. The side face of the pressure rod 34 is matched with the first guide rail 311 and the second guide rail 312 of the guide rail sleeve 310.

[0036] The locking button 32 is located outside the pressure rod 34. When the locking button 32 is pressed, the pressure rod 34 moves inward along the first guide rail 311 and the second guide rail 312 of the guide rail sleeve 310, and pushes the locking piece 35 inward by pushing the inner end face of the locking piece 35. The locking pressure rod is clamped between the ratchet teeth of the ratchet wheel 37, so that the ratchet wheel 37 can only rotate in the direction of tightening the tensioning rope 1. If the pressing of the locking button 32 is stopped at this time, the locking button 32 is reset under the action of the button spring 39. The outer end face of the locking piece 35 is pushed by the end face of the second guide rail 312 of the guide rail sleeve 310, so that the locking piece 35 cannot be reset, and the locking pressure rod remains in the locked state.

[0037] When the locking button 32 is pressed again, the pressure rod 34 moves inward along the first guide rail 311 and the second guide rail 312 on the guide rail sleeve 310, and again pushes against the inside of the end face of the locking piece 35 to move the locking piece 35 downward. Due to the cooperation of the outside of the end face of the locking piece 35 and the end face inclined surface of the first guide rail 311 and the second guide rail 312, the locking piece 35 moves inward and deflects under the action of the inclined surface at the end of the second guide rail 312, until the outside of the cross section of the locking piece 35 is in contact with the inclined surface at the end of the shorter first guide rail 311. At this time, the locking piece 35 moves outward together with the locking pressure rod under the action of the pressure rod spring 318, the locking pressure rod is separated from the ratchet teeth of the ratchet wheel 37, and the ratchet wheel 37 is no longer locked and can rotate freely. At this time, the first hook 2 and the second hook 4 can be pulled to expand the tension rope 1.

[0038] Therefore, when the locking button 32 is pressed repeatedly, the winding adjustment mechanism 3 can be switched between the locked state and the unlocked state of the tension rope 1 in sequence, and the working length of the tension rope 1 can be adjusted as needed or the tension rope 1 can be used for exercise.

[0039] As a preferred embodiment, the effective number of turns of the button spring 39 and the pressure rod spring 318 should be at least two turns, and the maximum elastic force range of the button spring 39 and the pressure rod spring 318 should be between 0-1CM, so that when the locking button 32 is pressed, the locking pressure rod moves downward by exactly 1CM, which can limit the movement of the ratchet wheel 37 and better realize the limiting of the tension rope 1.

[0040] As a preferred embodiment, the effective number of turns of the reset spring 321 should be at least five turns, and the maximum elastic force range of the reset spring 321 should be such that the maximum range of winding and unwinding of the tension rope 1 is at least 1M, so that the tension rope 1 can be automatically wound within 1M.

[0041] As a preferred embodiment, the number of locking pressure rods is five, which are the first locking pressure rod 313, the second locking pressure rod 314, the third locking pressure rod 315, the fourth locking pressure rod 316, and the fifth locking pressure rod 317. The five locking pressure rods are evenly distributed at the bottom end of the pressure plate 36 to ensure the stability of the structure. In addition, the locking pressure rod is cylindrical and has a smooth surface, which can be well clamped into the ratchet wheel 37. In particular, the locking pressure rod has the activity to move outward and inward around the ratchet wheel 37, and has a tendency to move inward, which ensures that when the locking pressure rod is clamped into the ratchet teeth of the ratchet wheel 37, the ratchet wheel 37 can only rotate in one direction, and thus the tension rope at this time can only be tightened and cannot be pulled open.

[0042] As a preferred embodiment, the shell of the winding adjustment mechanism body 31 is an olive type with angular ends and a circular arc middle surface, facilitating the smooth pulling out of the two side tension ropes 1. The square holes on the winding adjustment mechanism body 31 are located on the side edges of the two ends, and the square holes are respectively facing the first limiting rod 319 and the second limiting rod 320. After the tension rope 1 is pressed on the first limiting rod 319 and the second limiting rod 320, it respectively extends out of the two square holes of the winding adjustment mechanism body 31.

At this time, the locking button 32 is pressed, the rear middle part of the locking button 32 is fixedly moved down by 1CM through the pressure rod 34, the button spring 39, the first guide rail 311, the second guide rail 312, and the locking piece 35, the locking piece 35 drives the pressure plate 36 and the locking pressure rod to clamp the ratchet teeth of the ratchet 37 to limit, and then the locking button 32 is pressed again, the locking pressure rod moves up to cancel the limitation of the ratchet 37, the tension rope 1 is pulled out and retracted, and people can change the length or store the tension rope according to the needs of the body.

[0044] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application.
