Detailed Implementation

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] This utility model provides a strength training device, including a pedal, a training structure, and an auxiliary structure. The pedal is placed on the ground, and the training structure is set on the surface of the pedal. When the trainee is doing strength training, he steps on the pedal and pulls the training structure through the auxiliary structure, thereby achieving the purpose of strength training.

[0029] The following description, in conjunction with the accompanying drawings, details the various structures of the strength training device provided in the embodiments of this utility model, as well as the positional and connection relationships between these structures.

[0030] like Figure 1 As shown in the embodiment of this utility model, the pedal 10 has a set length, and the middle part of the surface of the pedal 10 includes a footrest 11. Training structures 20 are respectively provided on both sides of the footrest 11. In the strength training state, the trainee stands on the footrest 11, and the trainee's own weight applies a certain pressure to the pedal 10, which can ensure that the strength training equipment remains in a stable state when in use.

[0031] For example, an anti-slip structure, such as anti-slip rubber, can be provided at the bottom of the pedal 10. The friction between the anti-slip structure pedal 10 and the ground can further improve the stability of the pedal 10.

[0032] The training structure 20 includes a damper 21, which includes a pull-out end 22. The trainee pulls the damper 21 through the auxiliary structure 30. During the pull-out operation, the damper 21 provides resistance to the pull-out end 22 to achieve the purpose of strength training.

[0033] The auxiliary structure 30 is detachably connected to the pull-out end 22. By replacing different types of auxiliary structures 30, different strength training needs can be met. For example, the auxiliary structure 30 includes a pull ring, a crossbar, or a waist belt.

[0034] For example, the pull-out end 22 includes an annular structure with a detachable latch, which is detachably connected to the auxiliary structure 30.

[0035] like Figure 2 and Figure 3As shown in this embodiment of the present invention, the training structure 20 further includes a support 23. The support 23 has a certain height, and its bottom is fixedly connected to the surface of the pedal 10. The support 23 supports the damper 21 on the pedal 10. For example, a enclosure structure is also provided around the support 23. If the enclosure structure is a transparent panel, the enclosure structure plays a protective role, preventing debris or other personnel from accidentally touching the operating damper 21.

[0036] The damper 21 includes a take-up wheel 211, a transmission structure 212, and a damping structure 213. The take-up wheel 211 is rotatably connected to the bracket 23. The take-up wheel 211 includes a pull rope 24 and a coil spring disposed inside the take-up wheel 211. The pull rope 24 is wound on the coil spring. When the pull rope 24 is pulled out, the take-up wheel 211 rotates in one direction and the coil spring is tightened. When the force of the pull rope 24 disappears, the take-up wheel 211 rotates in the opposite direction under the action of the coil spring, and the pull rope 24 is automatically wound back. The end of the pull rope 24 is a pull-out end 22.

[0037] The take-up wheel 211 includes a rolling bearing 2111, and the transmission structure 212 includes a one-way needle roller bearing 2121. The rolling bearing 2111 and the one-way needle roller bearing 2121 are connected by a rotating shaft. When the pull rope 24 is pulled out, the take-up wheel 211 rotates, which in turn drives the transmission structure 212 to rotate. When the take-up wheel 211 rotates in the opposite direction, the one-way needle roller bearing 2121 on the transmission structure 212 prevents the transmission structure 212 from rotating with it.

[0038] The transmission structure 212 is connected to the damping structure 213, and the damping structure 213 is rotatably connected to the support 23. During the rotation of the transmission structure 212, the damping structure 213 provides damping force and provides a certain resistance to the transmission structure 212. Under the action of this resistance, the trainee needs to apply a certain force to the take-up wheel 211 to make it rotate, thereby achieving the purpose of strength training.

[0039] In this embodiment of the utility model, the strength training equipment includes a detection device 40, which is mounted on a bracket 23 on one side of the take-up wheel 211. The detection device 40 is used to detect the number of rotations of the take-up wheel 211.

[0040] For example, a magnet 2131 is set on the take-up wheel 211, and a sensor with a fixed position is set on the bracket 23 on the opposite side of the magnet 2131. The sensor senses the magnetic change of the magnet 2131 to achieve the purpose of recording the number of rotations.

[0041] Continue to refer to Figure 2 and Figure 3As shown in the embodiment of this utility model, the damping structure 213 includes a magnet 2131, a metal flywheel 2132, and an adjuster 2133; the magnet 2131 is located on one side of the metal flywheel 2132 along the radial direction of the metal flywheel 2132 and is spaced apart from the metal flywheel 2132; the adjuster 2133 is connected to the magnet 2131 and is used to adjust the distance between the magnet 2131 and the metal flywheel 2132 to adjust the resistance value of the damping structure 213.

[0042] The adjuster 2133 can change the linear distance between the magnet 2131 and the metal flywheel 2132. When the distance between them decreases, the resistance value of the damping structure 213 increases, and vice versa. For example, the adjuster 2133 is located at the top of the support 23 for easy adjustment by the trainee.

[0043] In this embodiment of the invention, the take-up box wheel 211 and the metal flywheel 2132 are connected by a transmission structure 212, thereby enabling the take-up box wheel 211 to drive the metal flywheel 2132 to rotate. For example, the transmission structure 212 includes a primary transmission wheel 2122 and a secondary transmission wheel 2123. The diameter of the secondary transmission wheel 2123 is smaller than the diameter of the primary transmission wheel 2122, and the diameter of the primary transmission wheel 2122 is smaller than the diameter of the metal flywheel 2132. Setting the diameter of the metal flywheel 2132 slightly larger ensures that the metal flywheel 2132 has a certain rotational speed and also ensures the effect of magnetic resistance.

[0044] The unidirectional needle roller bearing 2121 is located on the primary drive wheel 2122. The metal flywheel 2132 is connected to the drive wheel 2134. The primary drive wheel 2122 and the secondary drive wheel 2123, and the secondary drive wheel 2123 and the drive wheel 2134 are respectively connected by a transmission belt 2124. When the take-up box wheel 211 rotates, it drives the primary drive wheel 2122 to rotate. The primary drive wheel 2122 drives the secondary drive wheel 2123 to rotate via the transmission belt 2124. The drive wheel 2134 is coaxial with the metal flywheel 2132. The rotation of the secondary drive wheel 2123 drives the drive wheel 2134 to rotate via the transmission belt 2124, ultimately causing the metal flywheel 2132 to rotate. Under the action of resistance, the rotation of the metal flywheel 2132 is restricted, preventing the take-up box wheel 211 from being easily rotated, thereby achieving the purpose of strength training.

[0045] For example, the pedal 10 is provided with a receiving groove 12, and a mounting bracket 121 is provided on the side wall of the receiving groove 12. Multiple mounting positions are provided on the mounting bracket 121 along the depth direction of the receiving groove 12, such as strip-shaped holes or multiple spaced mounting holes. The secondary transmission wheel 2123 is used to connect to mounting positions at different depths to adjust the tension of the transmission belt 2124. Keeping the transmission belt 2124 under a certain tension ensures the stability of the transmission.

[0046] like Figure 4 and Figure 5 As shown in the embodiment of this utility model, the adjuster 2133 further includes a magnet base 21331 and an adjustment knob; the magnet 2131 is disposed on the magnet base 21331, one end of the magnet base 21331 is rotatably connected to the top of the bracket 23, and the other end is provided with an adjustment knob, which is used to adjust the distance between the magnet base 21331 and the metal flywheel 2132.

[0047] By rotating the adjustment knob, the distance between the magnet base 21331 and the metal flywheel 2132 can be driven. The size of this distance determines the resistance value. That is, the resistance value increases as the magnet base 21331 moves closer to the metal flywheel 2132, and decreases as it moves further away.

[0048] Specifically, the adjustment knob includes a dial 21332, a lever 21333, and a first spiral step 21334; the magnet base 21331 is provided with a through hole and a second spiral step 21335, the lever 21333 passes through the through hole, and the platform of the first spiral step 21334 is in contact with the platform of the second spiral step 21335. By rotating the lever 21333, the first spiral step 21334 presses the second spiral step 21335, so that the magnet base 21331 moves towards the metal flywheel 2132.

[0049] As the lever 21333 rotates, the first spiral step 21334 rotates synchronously. The surface of the first spiral step 21334 gradually increases in height along the axial direction, causing the surface of the first spiral step 21334 to press down on the surface of the second spiral step 21335. With the adjustment knob position unchanged, the magnet base 21331 is pressed down and moved. The dial 21332 has teeth; the trainee can manually rotate the dial 21332 to rotate the lever 21333.

[0050] When the knob 21332 is rotated in the reverse direction, the force exerted by the platform of the first spiral step 21334 on the platform of the second spiral step 21335 gradually decreases, the downward pressure of the magnet base 21331 disappears, and the magnet base 21331 can be reset. In this embodiment of the invention, the adjusting knob also includes a spring-loaded structure 21336; the spring-loaded structure 21336 abuts against the magnet base 21331, and when the knob 21333 is rotated in the reverse direction, the spring-loaded structure 21336 drives the magnet base 21331 to move away from the metal flywheel 2132.

[0051] For example, the spring-loaded structure 21336 includes a spring sleeved on the rotating rod 21333 and located on the side of the magnet seat 21331 away from the second spiral step 21335. As the force exerted by the first spiral step 21334 on the second spiral step 21335 gradually decreases, the magnet seat 21331 moves in the reset direction under the action of the spring's rebound force.

[0052] In this embodiment of the application, the strength training device further includes a display screen 50, which is used to display training data information, such as the current resistance level, training time, and calorie consumption.

[0053] For example, the adjustment knob also includes a potentiometer, which is located at the top of the lever 21333 and can rotate synchronously with the lever 21333. As the lever rotates, the angle of the dial can be read through the potentiometer to identify the position of the magnet base 21331, thereby determining the resistance level of the damping structure 213.

[0054] For example, the display screen 50 is located at the top of the training structure 20. Similarly, the regulator 2133, power supply structure, etc. are also located at the top of the training structure 20. This location makes it convenient for trainees to operate and obtain information values, further improving the convenience of the strength training equipment.

[0055] This utility model provides a strength training device. In use, the trainee, positioned at the foot pedal 11 of the pedal 10, pulls on the auxiliary structures 30 on both sides to achieve the purpose of strength training. The specific part of the training is determined by the auxiliary structures 30. For example, if the auxiliary structure 30 is a pull ring, the trainee can pull it with both hands to train their arms; if the auxiliary structure 30 is a horizontal bar, the trainee can perform lifting exercises. This utility model's technical solution utilizes a foot pedal design, employing the trainee's own weight to provide gravity for the device, resulting in good stability. Furthermore, the strength training device is multifunctional, meeting various training needs, saving costs, and reducing the space occupied by the device.
