Detailed implementation mode

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Embodiment 1

[0035] Please refer to Figures 1 to 11 , the present invention provides a technical solution: a tensile back muscle trainer for physical education teaching, including: a stabilizing frame 72, a seat cushion 1 and a counterweight frame 2. The stabilizing frame 72 is connected to the counterweight frame 2. A seat cushion 1 is connected to the stabilizing frame 72. A plurality of counterweights 4 are placed on the counterweight frame 2. A towing rope 5 is connected to the stabilizing frame 72. A quantitative rod 6 is connected to the towing rope 5. A plurality of first pulleys 10 are connected to the stabilizing frame 72. The towing rope 5 is connected to the first pulley. The other end of the towing rope 5 is connected to a handle 9. The stabilizing frame 72 fixes the seat cushion 1. The user sits on the seat cushion 1 and drives the towing rope 5 by pulling the handle 9. The quantitative rod 6 connected to the towing rope 5 is inserted into the counterweight 4, and then the counterweight 4 can be pulled. A leg limiting rod 3 is connected to the stabilizing frame 72, and thus the position of the legs can be limited and fixed;

[0036] It further includes:

[0037] An adjusting assembly, which is connected to the stabilizing frame 72. The adjusting assembly adjusts the height of the handle 9 according to the height of the user, prevents the position of the handle 9 from not corresponding to the position of the user, prevents the training posture of the user from being unstandard, affects the training effect of the user, and causes the trapezius muscle to be overused during the training process, resulting in trapezius muscle hyperplasia;

[0038] The rewinding assembly 15 is connected to the adjustment assembly, and the rewinding assembly 15 is connected to the traction rope 5. The rewinding assembly 15 winds and unwinds the traction rope 5 according to the height of the handle 9. When the adjustment assembly adjusts the position of the handle 9, the rewinding assembly 15 adjusts its position according to the handle 9 to wind or unwind the traction rope 5, thereby preventing the traction rope 5 from being too loose or too tight and affecting the user's training effect.

[0039] The positioning assembly 7 is connected to the stabilizing frame 72 and corresponds to the seat cushion 1. The positioning assembly 7 limits the position of the user. Through the positioning assembly 7, the training posture of the user can be limited, and the limiting force on the user can be adjusted according to the training weight of the user, thereby ensuring that the user trains in a standard posture and preventing the trapezius muscle from being overused due to non-standard training postures, resulting in trapezius muscle hyperplasia.

[0040] The adjustment assembly includes a first support rod 71 connected to the stabilizing frame 72. A measuring member 8 is connected to the support frame. The measuring member 8 is used to measure the height of the user. An adjusting member 13 is connected to the first support rod 71. The adjusting member 13 is used to adjust the height of the first support rod 71. By setting the measuring member 8, the height of the user can be measured. Then, according to the height of the user, the adjusting member 13 is activated. The adjusting member 13 can drive the first support rod 71 to perform vertical adjustment. By adjusting the first support rod 71, the height of the handle 9 can be adjusted, so that the height of the handle 9 can be adjusted according to the height of the user, preventing the position of the handle 9 from not corresponding to the position of the user.

[0041] The measuring member 8 includes a cross plate 11 connected to the first support rod 71. An infrared height measuring instrument 12 is connected to the cross plate 11, and the infrared height measuring instrument 12 is connected to the seat cushion 1. The infrared height measuring instrument 12 is used to measure the height of the user. By setting the cross plate 11, the infrared height measuring instrument 12 can be fixed. When the user trains, the user sits on the seat cushion 1, and the infrared height measuring instrument 12 can detect the height of the user. Then, according to the detection result of the infrared height measuring instrument 12, the adjusting member 13 is activated.

[0042] The adjusting member 13 includes a first groove opened on the stabilizing frame 72. The first groove is slidably connected to the first support rod 71.

A driving member 20 is connected to the first groove, and the driving member 20 is connected to the tooth grooves on the moving plate 131. By setting the first groove, the moving plate 131 and the driving member 20 can be protected, thereby extending the service life of the driving member 20. The driving member 20 can drive the moving plate 131 to move vertically in the groove, thereby adjusting the first support rod 71 to move vertically and adjusting the position of the handle 9. A spring 22 is connected to the bottom end of the moving plate 131, and the spring 22 can make the moving plate 131 return to its original position.

[0043] The driving member 20 includes a first motor 21 which is installed on the inner wall of the first groove. A driving gear 23 is connected to the output shaft of the first motor 21. The driving gear 23 is used to drive the moving plate 131 to move. The first motor 21 is started according to the detection result of the infrared height measuring instrument 12. The first motor 21 drives the driving gear 23 to rotate. The driving gear 23 meshes with the tooth groove on the moving plate 131, thereby driving the moving plate 131 to move vertically, and further driving the first support rod 71 to move vertically.

Different-position electromagnets can be started according to the detection result of the infrared height measuring instrument 12, and then the first metal plate 141, the second metal plate 142 and the third metal plate 143 are respectively triggered to slide out of the placement grooves. The vertical movement of the moving plate 131 presses against the first metal plate 141, the second metal plate 142 and the third metal plate 143. The first switch 341, the second switch 342 and the third switch 343 are used to turn off the first motor 21. When the moving plate 131 presses against the first metal plate 141, the second metal plate 142 and the third metal plate 143 and triggers the first switch 341, the second switch 342 and the third switch 343, the first motor 21 is turned off, thereby adjusting the position of the handle 9.

[0045] The winding component 15 includes a second groove 17 which is formed in the first support rod 71. A second motor 18 is connected to the second groove 17. A second pulley 19 is connected to the output shaft of the second motor 18. The second pulley 19 is connected to the traction rope 5. A control member 151 is connected to the output shaft of the second motor 18. The second motor 18 can be protected by being arranged in the second groove 17. When the first switch 341, the second switch 342 and the third switch 343 are triggered, the control member 151 and the second motor 18 are started while the first motor 21 is turned off. The second motor 18 drives the second pulley 19 to rotate, thereby adjusting the length of the traction rope 5 and ensuring that the traction rope 5 is within the standard range.

[0046] The control member 151 includes a tension sensor 33. The tension sensor 33 is connected to the metering rod 6 and is also connected to the towing rope 5. By means of the tension sensor 33, the tension of the towing rope 5 can be detected. When the support rod 71 is adjusted and the tension of the towing rope 5 is greater than the standard tension value, the second motor 18 rotates forward, driving the second pulley 19 to rotate forward, thereby extending the towing rope 5. When the tension of the towing rope 5 is less than the standard tension value, the second motor 18 rotates in reverse, driving the second pulley 19 to rotate in reverse, thereby tightening the towing rope 5.
