[0029] In order to better understand the purpose, structure and function of the utility model, the tension training device of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 4 As shown, the tension training device provided by the utility model includes a fitness platform 1, which is a flat rectangular structure. The upper end surface of the fitness platform 1 is a platform. When performing tension training, the user stands on the platform and uses the user's own gravity to resist the influence of the tension during tension training on the fitness platform 1, thereby achieving a balance between the user's own gravity and the tension, thereby abandoning the reliance on the large volume of the device itself to maintain stability, and making the tension training device as a whole miniaturized and flat.

[0031] Furthermore, the fitness platform 1 is provided with a wire outlet hole 11, one end of the pull rope 3 passes through the wire outlet hole 11 of the fitness platform 1, and the other end of the pull rope 3 is connected to the motor assembly 2 inside the fitness platform 1. The motor assembly 2 is a pancake-shaped motor, and the motor assembly 2 is flatly arranged inside the fitness platform 1. The output torque of the motor assembly 2 provides resistance to the pulling of the pull rope 3, thereby achieving the purpose of tension training. The motor assembly 2 in the embodiment of the utility model is a pancake-shaped servo motor. When in use, the motor output torque is adjusted by the controller as the source of resistance. The user resists the motor torque to achieve the purpose of strength training.

[0032] Furthermore, a pulley assembly 4 is also provided in the fitness platform 1, and the pulley assembly 4 is provided at the outlet hole 11. The pull rope 3 is extended from the motor assembly 2 and connected to the pulley assembly 4, and the pull rope 3 is limited to a preset motion track by the pulley assembly 4. The utility model can not only change the motion direction of the pull rope 3 by providing the pulley assembly 4, but also reduce the resistance of the pull rope 3 when it is pulled by the pulley assembly 4, which can effectively prevent the pull rope 3 from being worn.

[0033] Specifically, the pulley assembly 4 includes a horizontal pulley group 41 and a vertical pulley 42. The horizontal pulley group 41 includes two pulleys arranged opposite to each other. The horizontal pulley group 41 is arranged at one end close to the motor assembly 2. The pull rope 3 passes through the middle of the two pulleys of the horizontal pulley group 41, which can limit the movement trajectory of the pull rope 3 from the motor assembly 2 to the wire outlet hole 11. The vertical pulley 42 is arranged at one end close to the wire outlet hole 11. The axial direction of the vertical pulley 42 is perpendicular to the axial direction of the horizontal pulley group 41, which can turn the horizontal movement of the pull rope 3 to the vertical movement. Then the pull rope 3 passes through the wire outlet hole 11 and extends to the outside of the fitness platform 1, which is convenient for the user to pull out the pull rope 3 from the vertical direction.

[0034] Furthermore, the end surface of the motor assembly 2 is provided with a drawstring 3 receiving groove, and the drawstring 3 is horizontally wound into the drawstring 3 receiving groove, one end of the drawstring 3 is connected to the rotating shaft of the motor assembly 2, and the other end extends out of the drawstring 3 receiving groove. The utility model makes the drawstring 3 flat and wound in the drawstring 3 receiving groove, so that the winding method is safer and more convenient, and the drawstring 3 is prevented from being wound inside the fitness platform 1, and at the same time, the motor assembly 2 can be made thinner as a whole, thereby making the tension training device flatter as a whole.

[0035] Furthermore, two wire outlet holes 11 are provided on the fitness platform 1 in the practical embodiment, and the two wire outlet holes 11 are respectively provided on both sides of the platform. Two motor assemblies 2 corresponding to the wire outlet holes 11 are provided inside the fitness platform 1. The user pulls out the pull rope 3 from both sides to perform tension training for the left and right hands at the same time.

[0036] Furthermore, a display screen 12 is provided on one side of the platform of the fitness platform 1, and the display screen 12 is connected to the controller in the fitness platform 1, and the display screen 12 can display the user's usage parameters and / or adjust the torque of the motor assembly 2. The user can more intuitively understand his own exercise intensity and adjust the training intensity according to his own needs, making the tension trainer more intelligent.

[0037] Furthermore, the fitness platform 1 includes a frame structure and a decorative cover outside the frame structure, and the motor assembly 2 is fixedly connected to the frame structure. The frame structure is a stable metal structure, which can improve the overall load-bearing capacity of the fitness platform 1 and provide a reliable reaction force to resist the tensile force for the motor assembly 2. The decorative cover wraps the frame structure to form the outer side of the fitness platform 1, so that the overall appearance of the fitness platform 1 is more beautiful. In addition, ventilation holes are also provided on the decorative cover surface to facilitate the heat dissipation of the internal motor and controller.

[0038] In addition, a roller is provided at one end of the fitness platform 1, so that the user can drag the tension training device and the transportation of the tension training device is more convenient.

[0039] Furthermore, the drawstring 3 of the outlet hole 11 is connected to the connector 5. Figure 5-Figure 7 A structural schematic diagram of a connector 5 according to an embodiment of the utility model is given. As can be seen from the figure, the connector 5 includes an inner buckle 52 and a shell 51 sleeved on the outer side of the inner buckle 52, wherein an insertion groove 521 is provided on the inner buckle 52 for the pull ring 61 to be inserted from the insertion groove 521, and a clamping groove 522 is provided in the circumferential direction of the insertion groove 521. The clamping groove 522 includes an entry section and a locking section that are connected to each other. The entry section is connected to the insertion groove 521 on the inner buckle 52, and the locking section is provided with a pull ring 61 accommodating space relative to the entry section. The pull ring 61 is inserted into the insertion groove 521, and by rotating the pull ring 61, the pull ring 61 enters the entry section of the clamping groove 522 and then enters the locking section. An elastic member corresponding to the clamping groove 522 is also provided on the inner buckle 52, and the elastic member abuts the pull ring 61 against the locking section on the clamping groove 522 to complete the position locking of the pull ring 61. At this time, the pull ring 61 is in the working position. One end of the pull ring 61 is connected to the connector 5, and the other end is connected to the tension handle 6. That is, the utility model can connect different tension handles 6 or other tension training equipment to the same pull ring 61, and connect them to the tension training device through the pull ring 61, thereby improving the universality of the tension training device.

[0040] Furthermore, the pull ring 61 accommodation space of the slot 522 is a hook-shaped structure formed by the side wall of the inner buckle 52. When the pull ring 61 enters the locking section, the elastic member pushes the pull ring 61 into the hook-shaped structure formed by the side wall of the inner buckle 52, so that the position of the pull ring 61 is locked. The elastic member is a spring 54, which is sleeved between the inner buckle 52 and the housing 51. As shown in the figure, the bottom end of the inner buckle 52 protrudes from the body of the inner buckle 52, so that one end of the spring 54 abuts against the inner side of the protruding structure at the bottom end of the inner buckle 52, so that the spring 54 will not slide out on the inner buckle 52.

[0041] During tension training, the tension handle 6 is subjected to an upward tension in the opposite direction to the downward tension from the pull rope 3 on the inner buckle 52 . The hook structure on the inner buckle 52 prevents the tension handle 6 from freely moving in the vertical and horizontal directions, thereby achieving relative stability of the structure.

[0042] Furthermore, a through slot 511 corresponding to the plug-in slot 521 is provided on the housing 51, and the through slot 511 is flush with the plug-in slot 521. The housing 51 can rotate around the circumferential direction of the inner buckle 52, and the pull ring 61 is inserted into the plug-in slot 521 through the through slot 511 on the housing 51. When the pull ring 61 is rotated, the housing 51 can rotate together with the pull ring 61, thereby completing the position locking of the pull ring 61. The utility model sleeves the housing 51 on the outside of the inner buckle 52, so that when the pull ring 61 is locked in the slot 522, the through slot 511 of the housing 51 limits the left and right position of the pull ring 61, so that the pull ring 61 will not shake left and right, thereby improving the training experience of the user during training. At the same time, by sleeved on the outside of the inner buckle 52 by the housing 51, the elastic member and other devices can be hidden in the housing 51, so that the overall structure of the connector is compact and the appearance is beautiful.

[0043] Furthermore, a limiting groove 523 is also provided in the circumferential direction of the inner buckle 52, and the housing 51 is connected to the limiting groove 523 by a fastening screw 512, so that the ball shell rotates around the circumferential direction of the inner buckle 52 within the angle limited by the limiting groove 523. Specifically, a threaded hole is provided on the housing 51, and the fastening screw 512 is relatively fixedly connected to the housing 51 through the threaded hole on the housing 51, and the other end of the fastening screw 512 passes through the inner side of the housing 51 and is embedded in the limiting groove 523 of the inner buckle 52. At this time, the limiting groove 523 limits the movement of the housing 51 in the axial direction of the inner buckle 52, so that the housing 51 will not fall off the inner buckle 52. At the same time, the limiting groove 523 also limits the rotation angle of the housing 51 in the circumferential direction of the inner buckle 52, which is more convenient for quickly adjusting the through groove 511 of the housing 51 to the position corresponding to the plug-in groove 521 of the inner buckle 52 when the pull ring 61 is plugged in.

[0044] Furthermore, there may be two limiting grooves 523 on the inner buckle 52 of the embodiment of the utility model, and the housing 51 is respectively connected to the two limiting grooves 523 by two fastening screws 512. Among them, a reset elastic member may also be provided in at least one limiting groove 523, and the reset elastic member applies a driving force to the fastening screw 512, and the driving force is in the direction of the through groove 511 of the housing 51 at the hook structure of the card slot 522, and is reset to the position corresponding to the plug-in slot 521. After the pull ring 61 is removed from the connector 5, under the action of the reset elastic member, the through groove 511 of the housing 51 is always located at the position corresponding to the plug-in slot 521 of the inner buckle 52, so that the pull ring 61 can be quickly inserted when the belt connector is subsequently plugged in. It can be understood that at this time, the limiting groove 523 limits the movement angle of the shell 51, including the position corresponding to the through groove 511 of the shell 51 and the plug-in groove 521 of the inner buckle 52, to the rotation angle between the through groove 511 of the shell 51 and the hook-shaped structure of the card slot 522. Of course, due to the role of the card slot 522 on the inner buckle 52, the limiting groove 523 exceeds the hook-shaped structure of the through groove 511 of the shell 51 at the card slot 522, which can also meet the role of the limiting groove 523 in the embodiment of the utility model. As shown in the accompanying drawings, in the embodiment of the utility model, the limiting groove 523 is preferably arranged at the bottom of the inner buckle 52, and the limiting groove 523 is isolated from the plug-in groove 521 and the card slot 522.

[0045] Furthermore, the connector 5 provided in the embodiment of the utility model also includes a soft pad 53, which is arranged at the bottom end of the inner buckle 52. A rope threading hole is arranged in the middle of the soft pad 53, and the rope body is connected to the inner buckle 52 through the rope threading hole on the soft pad. The soft pad 53 provided by the utility model prevents the connector 5 from being bumped when it rebounds to the surface of the tension training device when the tension handle 6 is released. In addition, when plugging in the pull ring 61, first pinch the soft pad 53 to limit the internal insertion of the inner buckle 52, and at the same time vertically insert the pull ring 61 downward. When the bottom position of the pull ring 61 is lower than the rotatable position of the inner buckle 52 (i.e., the entry section of the plug-in slot 521), turn the pull ring 61 clockwise so that the pull ring 61 enters the locking section of the plug-in slot 521.

[0046] Furthermore, the elastic member provided by the utility model is a spring 54 sleeved on the inner buckle 52, and the spring 54 is located on the inner side of the housing 51. When inserting the pull ring 61 into the connector 5, it is necessary to first resist the elastic force of the spring 54 and move in the circumferential direction of the inner buckle 52 so that the pull ring 61 enters the pull ring 61 accommodating space in the slot 522. When the pull ring 61 needs to be removed, the pull ring 61 is first pressed downward so that the pull ring 61 is separated from the pull ring 61 accommodating space in the slot 522, and then the pull ring 61 is reversely rotated to the slot 522, and the pull ring 61 can be easily removed. In addition, it should be noted that when locking the pull ring 61, due to the limiting effect of the side wall of the slot 522 formed by the inner buckle 52, it is only necessary to rotate the pull ring 61 to a position where it cannot rotate to loosen the pull ring 61, and the pull ring 61 can be locked under the action of the elastic force of the spring 54.

[0047] Furthermore, the inner buckle 52 provided in the embodiment of the utility model is a cylindrical structure with a protruding bottom end, and the shell 51 is a spherical structure. An embedding groove corresponding to the inner buckle 52 is provided inside the shell 51, so that the shell 51 covers the outer side of the inner buckle 52. The outer contours of the shell 51, the inner buckle 52 and the cushion 53 together form a sphere, making the overall structure of the connector 5 compact and beautiful, which not only saves space but also beautifies the appearance of the tension training device.

[0048] Furthermore, the connector 5 of the present invention is spherical in structure as a whole, that is, the exposed parts of the shell, the inner buckle 52, the cushion 53 and other components are spherical as a whole, so that the connector 5 has a compact structure and beautiful appearance.

[0049] Furthermore, an embodiment of the utility model also provides a tension training device, which includes the connector 5 described in the above embodiment, one end of the connector 5 is connected to the pull rope 3 of the tension training device, and the other end is used to replace different forms of tension handles 6 and fitness accessories.

[0050] The connector 5 of the utility model, i.e. the tension training device, has the following advantages:

[0051] 1. The pancake-shaped motor in the fitness platform 1 provides torque to the pull rope 3, so that the overall tension training device can be miniaturized and flattened.

[0052] 2. The user stands on the platform of the fitness platform 1 and uses his own weight to resist the pulling force on the tension rope, thereby abandoning the reliance on the large volume of the equipment itself to maintain stability, which can further miniaturize and flatten the overall tension training device.

[0053] 3. The tension rope is horizontally wound in the rope storage groove 3 on the end face of the motor assembly 2. While the winding method is safer and more convenient, the motor assembly 2 is thinner as a whole, thereby making the tension trainer flatter as a whole.

[0054] 4. The pulley assembly 4 is used to limit the movement trajectory of the tension rope, making the user's operation smoother and avoiding the wear of the tension rope.

[0055] 5. The connector 5 is set as a detachable handle connector 5 so that the tension trainer can be adapted to different training handles, thereby improving the user experience.

[0056] 6. By adjusting the torque of the motor through the display screen 12, the user can adjust the training needs according to his own needs, making the tension trainer more intelligent.

[0057] 7. By arranging a pulley on the fitness platform 1, it is more convenient to carry the tension training device.
