DETAILED DESCRIPTION

[0038] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0039] In one embodiment, if Figure 1 and Figure 3 As shown, the present invention provides a speed skating strength training device, comprising:

[0040] A base 3, on which a seat 1 is mounted via a position adjustment component, the position adjustment component being used to adjust the riding position of the seat 1, and a handle 5 is also provided on the base 3, and along the riding direction, the handle 5 is located at the front side of the seat 1;

[0041] A pedal assembly, the pedal assembly comprising foot pedals 41 arranged in pairs, and the foot pedals arranged in pairs are arranged symmetrically along the pedal driving direction, and the foot pedals 41 are used to place the trainer's feet and simulate the riding posture;

[0042] The torsion mechanism 2 is arranged on the base 3, and the torsion mechanism 2 includes a torsion drive component and a mounting seat 26. The output end of the torsion drive component is transmission-connected to the mounting seat 26, and the input end of the torsion drive component is transmission-connected to the output end of the pedal component. The seat 1 is arranged on the mounting seat 26. Driven by the torsion drive component, the mounting seat 26 drives the seat 1 to swing back and forth, wherein, when the pedal 41 on one side of the seat 1 rotates along the pedal driving direction and rotates from the highest point position to the lowest point position of the rotation trajectory, the outer end of the seat 1 on the same side of the pedal 41 swings from the upwardly inclined highest point position to the downwardly inclined lowest point position.

[0043] For example, see Figure 1 The adjustment component includes a first shift seat 31 and a second shift seat 32. The first shift seat 31 is arranged on the base 3. The shift end of the first shift seat 31 is fixedly provided with the second shift seat 32. The seat 1 is installed on the second shift seat 32 through the mounting seat 26. The height is adjusted by the first shift seat 31, and the front and rear adjustment is performed by the second shift seat 32, so as to adjust the riding position of the seat 1 finally required by the trainer as a whole.

[0044] In the above embodiment, when the trainer sits on the seat 1 and pedals the pedal 41 to simulate riding, for example, when the pedal 41 rotates from the highest point position of the rotation trajectory to the rotation center height position of the pedal 41, the seat 1 swings from the outer end on the same side as the pedal 41 from the upward inclined highest point position to the horizontal initial position, and when the trainer continues to pedal, the pedal 41 continues to rotate and move down to the lowest point position, the root of the human thigh tends to swing down relative to the seat 1, and the outer end of the seat 1 continues to swing down in the above process, so that the seat 1 fits the natural movement trajectory of the human limbs, tilts on the same side as the trainer's hip twisting direction, reduces the burden on the lower limbs, makes the leg movement smoother, and reduces the friction between the inner thigh of the human body and the contact part of the seat.

[0045] It should be noted that, except for athletes, especially beginners of skating, trainers who perform lower limb strength training do not have such high requirements for training intensity. If they exercise by riding for a long time, it is very easy to cause friction damage to the roots of the thighs. They need to use the speed skating strength trainer provided by the present invention for training, so as to effectively reduce friction damage to individual parts of the human body.

[0046] In one embodiment, continue to refer to Figure 2 , Figure 3 and Figure 4 The torsion drive assembly includes a third pulley 245, a driving gear 246, a driven gear ring 247, a slide 25 and a torsion adjustment assembly. The output shaft of the third pulley 245 is rotatably connected to the cantilever 251, the cantilever 251 is fixedly connected to the slide 25, the slide 25 is slidably connected to the second shift seat 32, the output shaft of the third pulley 245 is fixedly connected to the driving gear 246, the driving gear 246 is meshed with the driven gear ring 247, and the side of the driven gear ring 247 away from the third pulley 245 is fixedly connected to the frame 2 48. The frame 248 is fixedly connected with a fourth main shaft 249. The output end of the fourth main shaft 249 passes through the slide 25 and is rotatably connected with the slide 25. A clearance groove 253 is opened in the slide 25. The fourth main shaft 249 is fixedly connected with a rotating block 261 at the position of the clearance groove 253. The rotating block 261 is fixedly set on the side of the mounting seat 26 away from the seat 1. The output end of the torsion adjustment component is connected with the third pulley 245 for transmission. The torsion adjustment component is used to transmit the third pulley 245 corresponding to the displacement of the seat 1.

[0047] In the above embodiment, the torsion adjustment component transmits the driving gear 246 through the third pulley 245, and with the help of the reduction transmission of the driving gear 246 and the driven gear ring 247, the fourth main shaft 249 drives the mounting seat 26 to swing for angle adjustment through the rotating block 261, thereby realizing the smooth swing of the seat 1.

[0048] Continue reading Figure 4 The slide seat 25 is provided with a convex rail 252 on one side facing the mounting seat 26, and the mounting seat 26 is provided with a groove 262, which is arranged corresponding to the convex rail 252, and the mounting seat 26 is slidably connected to the convex rail 252 through the groove 262. The swinging motion of the mounting seat 26 is supported by the limit constraint of the convex rail 252 and the groove 262.

[0049] For example, see Figure 7 , Figure 8 and Fig.10The torsion adjustment assembly includes a third transmission belt 243, a hook spring 242, a swing plate 24, an eccentric wheel 21 and a positioning shaft 23. The positioning shaft 23 is fixedly arranged on the base 3 through a positioning column 231. The positioning shaft 23 is rotatably connected to one end of the swing plate 24. The eccentric wheel 21 is rotatably connected to the second main shaft 22. The second main shaft 22 is fixedly arranged on the base 3 through a support 221. In the riding direction, the second main shaft 22 is located on the side of the first main shaft 42 away from the pedal 41, and the input end of the second main shaft 22 is transmission-connected to the output end of the pedal assembly. The eccentric wheel 21 is located above the swing plate 24, and the circumferential side surface of the eccentric wheel 21 is in frictional contact with the swing plate 24. The rotation trajectory direction of the maximum rotation radius point of the eccentric wheel 21 is the same as the rotation trajectory direction of the pedal 41 on the same side.

[0050] The swing plates 24 are arranged in pairs, the eccentric wheels 21 and the swing plates 24 are arranged correspondingly, and the paired eccentric wheels 21 are symmetrical about the axis center of the second main shaft 22, the swing directions of the paired swing plates 24 are opposite, and the outer ends of the swing plates 24 are transmission-connected to the transmission ends of the third transmission belt 243, wherein the outer end of one swing plate 24 is elastically connected to the third transmission belt 243.

[0051] For example, see Figure 8 The outer end of the swing plate 24 is fixedly connected with a hook ring 241, wherein the hook ring 241 of one swing plate 24 is transmission-connected to one transmission end of the third transmission belt 243 through a hook, and the hook ring 241 of the other swing plate 24 is transmission-connected to the other transmission end of the third transmission belt 243 through a hook spring 242, wherein the other transmission end of the third transmission belt 243 is provided with a plurality of hook holes 244, and the hook end of the hook spring 242 is transmission-connected to the third transmission belt 243 through the hook hole 244.

[0052] In the above embodiment, after the third transmission belt 243 is removed from the third pulley 245 and the position of the seat 1 is adjusted, one end of the third transmission belt 243 is hung on the hook ring 241 of a swing plate 24, and the other end of the third transmission belt 243 passes around the third pulley 245 and is hung on another swing plate 24 through the hook spring 242. At this time, the seat 1 is in the initial position and the swing plate 24 is in a horizontal position. After the trainer starts riding, the output end of the pedal assembly transmits the second main shaft 22, so that the swing plate 24 starts to swing, thereby driving the third pulley 245 to rotate with the help of the third transmission belt 243.

[0053] For example, see Figure 8The pedal assembly includes a first pulley 43, a second pulley 45 and a flywheel 44. The pedal 41 is rotatably connected to the first main shaft 42. The flywheel 44 is fixedly connected to the third main shaft 47. The third main shaft 47 is mounted on the base 3 through a bracket 46. In the riding direction, the third main shaft 47 is located between the first main shaft 42 and the positioning shaft 23. The first main shaft 42 is fixedly connected with the first pulley 43. The third main shaft 47 is fixedly connected with the first transmission roller 471 and the second transmission roller 472. The first transmission roller 471 and the second transmission roller 472 are respectively located on both sides of the flywheel 44. The first pulley 43 is connected to the first transmission roller 471 through a first transmission belt 431. The second pulley 45 is connected to the second transmission roller 472 through a second transmission belt 451.

[0054] The rotation speed of the first belt pulley 43 is the same as the rotation speed of the second belt pulley 45. Through the transmission of the above structure, the pedaling action of the human body and the swinging action of the seat 1 are coordinated.

[0055] For example, see Figure 1 and Fig. 9 , the bracket 46 is provided with a magnetic resistor 48, the handle 5 is fixedly provided on the base 3 through a mounting frame, and the mounting frame is provided with a resistor 51, and the resistor 51 is used to adjust the distance between the magnet of the magnetic resistor 48 and the flywheel 44. For example, the resistor 51 is a knob switch, and the knob angle corresponds to different resistance gears, thereby adjusting the rotation resistance of the flywheel 44 to increase the riding difficulty of the trainer, that is, to increase the training intensity of the lower limb strength. Moreover, the magnetic resistance adjustment is smooth and quiet, the resistance adjustment is accurate and can avoid mechanical wear.

[0056] For example, see Figure 5 and Figure 6 The seat 1 comprises a rear seat body 13, a front seat body 14, a side seat body 11 and a sealing bag 12. The rear seat body 13 and the front seat body 14 are respectively fixedly mounted on a mounting seat 26. Along the riding direction, the front seat body 14 is located in front of the rear seat body 13. Figure 5 As shown in FIG. (a), the side seats 11 are arranged in pairs, and the side seats 11 arranged in pairs are symmetrically arranged on both sides of the front seat 14. Figure 5 As shown in the middle (b), the side seat body 11 is rotatably connected to the rear seat body 13 via a rotating shaft 15, and a torsion spring is sleeved on the rotating shaft 15. A sealing bag 12 is provided at the rotating gap between the side seat body 11 and the rear seat body 13. When the trainer pushes down the pedal 41, for beginners who have the habit of pulling their thighs inward, the part where the thigh roots touch the seat 1 will swing down with the thighs through the side seat body 11. Figure 6The lowering position shown in the figure makes there no relative friction movement between the side seat body 11 and the limbs, and the side seat body 11 lowers with the thigh, making the leg movement smoother, and with the help of the sealing of the sealing bag 12, the position of the thigh root near the buttocks is prevented from being clamped, and the riding experience is good.

[0057] In one embodiment, the present invention further provides a method of using the above speed skating strength training device, comprising the following steps:

[0058] S1, adjusting the seat 1 to a riding position through the position adjustment component, and adjusting the riding resistance of the flywheel 44 according to training needs;

[0059] S2, the third transmission belt 243 is connected to the swing plate 24 through the hook spring 242, so that the swing plate 24 is in a horizontal position and the seat 1 is in an initial position;

[0060] S3. The foot pedal 41 is rotated along the pedal driving direction by the foot, and with the help of the transmission of the pedal assembly and the torsion drive assembly, the seat 1 on the mounting seat 26 swings back and forth. When the foot pedal 41 on one side rotates from the highest point position to the lowest point position of the rotation trajectory, the outer end of the seat 1 on the same side of the foot pedal 41 swings from the highest point position inclined upward to the lowest point position inclined downward.

[0061] The above method helps trainees to improve the strength of their lower limbs. During the training process, the seat 1 swings back and forth following the movement of the foot pedal 41, so that the seat 1 fits the natural movement trajectory of the human limbs and tilts to the same side as the trainee's hip twisting direction, thereby reducing the burden on the lower limbs and making the leg movements smoother, thereby reducing the friction between the inner thigh and the contact area of ​​the seat.

[0062] It should be noted that, when using the speed skating strength trainer, the trainer first adjusts the riding position of the seat 1 according to his / her own riding habits. Specifically, the height of the seat 1 is adjusted by means of the first shift seat 31, and the front and rear position of the seat 1 is adjusted by the second shift seat 32, so as to finally locate the riding position of the seat 1. According to the position of the seat 1 at this time, one end of the third transmission belt 243 is hung on a hook 241 on a swing plate 24, as shown in FIG. Figure 8 As shown, the other end passes through the third pulley 245 and is hooked on the hook ring 241 on another swing plate 24 by means of the hook spring 242, so that at this time, the swing plate 24 is in a horizontal position, and the foot pedal 41 is at the height position of the rotation center of the foot pedal 41, as shown in FIG. Figure 7 As shown, the resistor 51 is adjusted according to the lower limb strength training intensity requirement to adjust the distance between the magnetic resistor 48 and the flywheel 44;

[0063] The trainer starts the simulated cycling training by pedaling the pedal 41 and swinging the thigh downward, so that the pedal 41 moves downward from the rotation center height position of the pedal 41 to the lowest position, that is, the pedal 41 moves downward from the rotation center height position of the pedal 41 to the lowest position. Figure 7 Rotate the position shown to Fig.11 When in the position shown, the first pulley 43 drives the third main shaft 47 to rotate through the first transmission belt 431, and the third main shaft 47 drives the second pulley 45 to rotate through the second transmission belt 451, so that the second pulley 45 rotates through the second main shaft 22, and the second main shaft 22 drives the two eccentric wheels 21 to rotate. At this time, the rotation speed of the eccentric wheel 21 is the same as that of the pedal 41, and the rotation trajectory direction of the maximum rotation radius position of the eccentric wheel 21 on the same side is the same as the rotation trajectory direction of the pedal 41, as shown in FIG. Fig.10 As shown;

[0064] When the eccentric wheel 21 contacts the transmission swing plate 24, the driving gear 246 is engaged with the driven gear ring 247 by means of the transmission of the third transmission belt 243 and the third pulley 245, so that the fourth main shaft 249 drives the mounting seat 26 to rotate through the rotating block 261. Figure 3 In the position shown, the mounting seat 26 drives the seat 1 above it to swing clockwise, so that the thigh root tends to swing downward relative to the seat 1. Through the swinging of the seat 1, the seat 1 fits the natural movement trajectory of the human limbs and tilts to the same side as the trainer's hip twisting direction, reducing the burden on the lower limbs and making the leg movement smoother, thereby reducing the friction between the inner thigh of the human body and the contact part of the seat;

[0065] Moreover, for beginners who have the riding habit of pulling their thighs inward, when the part where the root of the thigh fits the seat 1 is swayed, the side seat body 11 swings down with the thigh, so that there is no relative friction movement between the side seat body 11 and the limbs, and the side seat body 11 swings down with the thigh, making the leg movement smoother, and with the help of the sealing of the sealing bag 12, the position of the root of the thigh near the buttocks is prevented from being clamped, so that the riding experience is good, and when the foot pedal 41 moves up, the side seat body 11 is reset to the initial position under the reset action of the torsion spring.

[0066] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
