Description

Technical Field

[0001] The present invention relates to the field of strength training, and particularly to a gantry fitness apparatus providing electronic resistance training. Background Art

[0002] The gantry fitness apparatus is an efficient and multi-functional fitness device that can be used to exercise muscle groups in various parts of the body, including, for example, chest training, back training, shoulder training, arm training, core training, and lower limb training, etc. It is not only suitable for commercial gyms, but also some miniaturized designs are suitable for home use, meeting the fitness needs in different scenarios.

[0003] Currently, most traditional gantries use barbell plates or iron plates as counterweights, and transfer the weight of the barbell plates to the hands or other parts of the body of the trainer through a pulley and rope system. If it is necessary to adjust the training intensity, the weight of the dumbbell barbell plates or iron plates needs to be changed. However, such a counterweight adjustment method has many problems: 1. Inaccurate counterweight adjustment: The weight of the barbell plates is usually in fixed specifications, such as 2.5 kg, 5 kg, 10 kg, etc., and continuous and precise weight adjustment cannot be achieved. During the training process, it may be necessary to make a jump selection between different weights, and it is difficult to find the exact weight that is most suitable for the current ability and training needs of the trainer. 2. Inconvenient counterweight adjustment: When it is necessary to replace barbell plates of different weights each time during training, it is necessary to manually disassemble and install the barbell plates or replace all the barbell plates. This process is relatively cumbersome, wasting training time and increasing the difficulty of counterweight adjustment. 3. There are safety hazards: During the process of adjusting the counterweight by the trainer, there may be a safety hazard that the dumbbell or iron block hits oneself if not careful.

[0004] In addition, the current gantry can only provide single-mode training and cannot achieve multi-mode training, thereby limiting the application of the gantry.

[0005] In addition, the current gantries are often large in volume and have a strong structure, and are not easy to disassemble and install. This all results in that whether moving indoors or transporting to other places, a large amount of space and a lot of manpower are required, increasing the handling cost and difficulty of the gantry. Moreover, for home fitness enthusiasts, the fixed gantry will occupy a large amount of indoor space, affecting the cleanliness and comfort of the living environment. For places such as gyms, if it is necessary to re-layout the venue or store multiple gantries, the non-easy-to-disassemble gantry will also bring greater pressure to the storage space and reduce the space utilization efficiency. Summary of the Invention

[0006] The purpose of the present invention is to provide a gantry fitness apparatus providing electronic resistance training, which uses an electronic cabin to replace the traditional counterweight block to provide electronic resistance, and optimizes the structural design of the gantry to provide a gantry fitness apparatus that is convenient for disassembly and assembly.

[0007] To achieve the above objectives, the present technical solution provides a smith machine fitness apparatus for providing electronic resistance training, comprising: a smith machine main body assembly, including a base frame, a vertical frame vertically arranged relative to the base frame, a top frame vertically arranged relative to the vertical frame and horizontally arranged relative to the base frame, and a tension frame connected between the top frame and the base frame, wherein the base frame, the vertical frame, and the top frame are an integral detachable and assembled structure; an electronic resistance assembly provided on the smith machine main body assembly for providing electronically adjustable output resistance; a pulley assembly provided on the smith machine main body assembly, including a movable pulley set connected to the electronic resistance assembly and a fixed pulley set mounted on the smith machine main body assembly; a tension assembly provided on the tension frame, including a tension handle connected to the tension frame; a tension rope is sequentially wound around the fixed pulley set and the movable pulley set, and the two free ends of the tension rope are respectively connected to the tension handles on both sides.

[0008] Compared with the prior art, the present technical solution has the following characteristics and beneficial effects:

[0009] 1. It has the effects of being easy to disassemble, assemble, and saving space: The base frame, the vertical frame, and the top frame of the smith machine main body assembly adopt an integral detachable and assembled structure. The vertical frame is rotatably arranged relative to the base frame, and the top frame is rotatably arranged relative to the vertical frame. During installation, it is rotated to be vertically fixed, and during disassembly, it is rotated to be horizontally stacked. For example, components such as the base frame rod, the vertical frame rod, and the top frame rod are combined through specific rotation installation steps, greatly reducing the floor area when not in use, facilitating handling and storage, and being also suitable for families or small gyms with limited space.

[0010] 2. It improves the training flexibility by providing electronically adjustable resistance: The electronic resistance assembly includes a resistance motor, a resistance adjuster, and a resistance output rope. By replacing the traditional mechanical counterweight with the electronic resistance assembly, functions such as stepless resistance adjustment, preset modes, and personalized settings are realized, meeting the requirements of different training stages and intensities.

[0011] 3. It provides multi-directional and multi-height tensile training to achieve flexible tensile adjustment: The connecting member of the tension assembly is sleeved outside the tension frame, and the tension rope connecting member is rotatably connected to the connecting member through a rotating shaft. The tension rope connecting member can rotate in multiple directions and achieve a 180° rotation, and can adjust the installation height on different sides of the tension frame, providing the trainer with diverse, multi-angle, and multi-height training positions to meet the training needs of different muscle groups.

[0012] 4. It has a detachable chin-up bar to enrich the training methods: The chin-up bar is detachably installed on the top frame and consists of two parallel chin-up bar bodies and reinforcing members, adopting a "bridge body" shape design and enhancing stability through reinforcing members in different directions. The trainer can install it as needed to add the chin-up training item and enrich the training functions and exercise methods of the overall fitness apparatus.

[0013] 5. Provide a motion training method linked with the APP: The electronic resistance of this solution can be linked with the APP or other intelligent devices to increase the fun of exercise while providing exercise records. Description of the Drawings

[0024] Embodiment 1

[0025] As Figure 1 shown, this solution proposes a gantry fitness apparatus for providing electronic resistance training, including:

[0026] The gantry main body assembly 10, including a base frame 11, a vertical frame 12 vertically arranged relative to the base frame 11, a top frame 13 vertically arranged relative to the vertical frame 12 and parallel to the base frame 11, and a tension frame 14 connected between the top frame 13 and the base frame 11, wherein the base frame 11, the vertical frame 12, and the top frame 13 are an integral disassembly and assembly structure;

[0027] An electronic resistance assembly 20 arranged on the gantry main body assembly 10, for providing electronically adjustable output resistance;

[0028] A pulley assembly 30 arranged on the gantry main body assembly 10, including a movable pulley group 31 connected to the electronic resistance assembly 20 and a fixed pulley group 32 installed on the gantry main body assembly 10;

[0029] A tension assembly 40 arranged on the tension frame 14, including a tension handle 44 connected to the tension frame 14;

[0030] The tension rope is sequentially wound around the fixed pulley group 32 and the movable pulley group 31, and the two free ends of the tension rope are respectively connected to the tension handles 44 on both sides.

[0031] Regarding the gantry main body assembly 10 of this solution:

[0032] Different from the traditional fixed gantry, the gantry main component 10 of this solution is designed with a structure that is easy to disassemble and assemble. The chassis 11, vertical frame 12, and top frame 13 of the gantry main component 10 are an integrated disassembly and assembly structure. Specifically, the vertical frame 12 of the gantry main body 10 of this solution is rotatably and movably arranged relative to the chassis 11, and the top frame 13 is rotatably and movably arranged relative to the vertical frame 12. Moreover, a lock structure that can be unlocked and locked is provided at the rotation positions of the chassis 11, vertical frame 12, and top frame 13. When the gantry main component 10 is in an uninstalled state or a disassembled state, the vertical frame 12 is stacked parallel to the chassis 11, and the top frame 13 is stacked parallel to the side of the vertical frame 12; when the gantry main component 10 is in an installed state, the vertical frame 12 is vertically fixed to the chassis 11, and the top frame 13 is also vertically fixed to the vertical frame 12.

[0033] That is, when it is necessary to install the gantry main component 10, unlock the lock structure at the rotation positions of the chassis 11, vertical frame 12, and top frame 13, rotate the vertical frame 12 relative to the chassis 11 to a relatively vertical position and then fix the rotation position, and rotate the top frame 13 relative to the vertical frame 12 to a relative vertical position and then lock the rotation position; when it is necessary to disassemble the gantry main component 10, unlock the lock structure at the rotation positions of the chassis 11, vertical frame 12, and top frame 13, and rotate the top frame 13 relative to the vertical frame 12 closer to a relatively parallel position, and rotate the vertical frame 12 relative to the chassis 11 closer to a relatively parallel position.

[0034] In order to realize the rotatable and movable arrangement of the chassis 11, vertical frame 12, and top frame 13, in some embodiments, the bottom end of the vertical frame 12 is movably connected to one end of the chassis 11 through a rotating part, and the top end of the vertical frame 12 is movably connected to one end of the top frame 13 through a rotating part. Or, in some other embodiments, the bottom end of the vertical frame 12 is sleeved or embedded on the chassis 11 and is movably connected through a pin shaft, and the top end of the vertical frame 12 is also sleeved or embedded on the top frame 13 and is movably connected through a pin shaft. At this time, the position where the pin shaft is located is the rotation position.

[0035] When adopting the method of rotatable and movable arrangement with a rotating part, in some embodiments, the rotating part includes two fixing plates rotatably connected through a pin shaft, and the two fixing plates are respectively fixed on the frame body that needs to rotate, and the rotation of the frame body is realized through the pin shaft; or, the rotating part includes one fixing plate, the fixing plate is fixed on the frame body that does not need to rotate, and the other frame body that needs to rotate is connected to the fixing plate through a pin shaft. For example, the fixing plate of the rotating part is fixed on the chassis 11, and the bottom end of the vertical frame 12 is rotatably connected to the fixing plate through a pin shaft to realize rotation; the fixing plate of the rotating part is fixed on the vertical frame 12, and the bottom end of the top frame 13 is rotatably connected to the fixing plate through a pin shaft to realize rotation. At this time, the position where the pin shaft is located is the rotation position. In a specific embodiment, in some embodiments, the chassis 11, vertical frame 12, and top frame 13 are connected by folding hinges.

[0036] To ensure the stability of the gantry fitness equipment during use, a lock structure that can be unlocked and locked is set at the rotation position. In some embodiments, the lock structure is a fixed pin or a nut, and at this time, the rotation position can be fixed by the fixed pin or the nut. To further reduce the floor area occupied by the bottom frame 11, the vertical frame 12, and the top frame 13 after folding, the vertical frame 12 rotates movably relative to the top surface of the bottom frame 11, and the top frame 13 rotates movably relative to the side surface of the vertical frame 12. At this time, when the gantry main body 10 is in an uninstalled state or a disassembled state, the vertical frame 12 is stacked parallel to the top surface of the bottom frame 11, and the top frame 13 is stacked parallel to the side surfaces of the vertical frame 12 and the bottom frame 11.

[0037] As Figure 2 shown, to form the overall gantry structure of the gantry, the bottom frame 11 of this solution further includes a first bottom frame rod 111, a second bottom frame rod 112, and a connecting bottom frame rod 113. The connecting bottom frame rod 113 is rotatably and movably connected to the first bottom frame rod 111 or the second bottom frame rod 112; the top frame 13 further includes a first top frame rod 131, a second top frame rod 132, and a connecting top frame rod 133. The connecting top frame rod 113 is rotatably and movably connected to the first top frame rod 131 or the second top frame rod 132; the vertical frame 12 includes a first vertical frame rod 121 and a second vertical frame rod 122; wherein the first vertical frame rod 121 is rotatably and movably arranged relative to the first bottom frame rod 111, and the first top frame rod 131 is rotatably and movably arranged relative to the first vertical frame rod 121; wherein the second vertical frame rod 122 is rotatably and movably arranged relative to the first bottom frame rod 112, and the second top frame rod 132 is rotatably and movably arranged relative to the second vertical frame rod 122. The rotatable and movable position is defined as the rotation position.

[0038] It should be noted that when the gantry main body assembly 10 is in an uninstalled state or a disassembled state, the connecting bottom frame rod 113 is stacked parallel to the side of the first bottom frame rod 111 or the second bottom frame rod 112, and the connecting top frame rod 133 is stacked parallel to the side of the first top frame rod 131 or the second top frame rod 132; when the gantry main body assembly 10 is in an installed state, the connecting bottom frame rod 113 fixedly connects the first bottom frame rod 111 and the second bottom frame rod 112, and the connecting top frame rod 133 fixedly connects the first top frame rod 131 and the second top frame rod 132, that is, at this time, the rotation positions of the connecting bottom frame rod 113 and the first bottom frame rod 111 or the second bottom frame rod 112 are fixed, and the rotation positions of the connecting top frame rod 133 and the first top frame rod 131 or the second top frame rod 132 are fixed.

[0039] In some embodiments, the bottom end of the connecting chassis rod 113 is movably connected to one end of the first chassis rod 111 or the second chassis rod 112 through a rotating member, and the bottom end of the connecting top frame rod 133 is movably connected to the side of the first top frame rod 131 or the second top frame rod 132 through a rotating member. Alternatively, in some other embodiments, the bottom end of the connecting chassis rod 113 is sleeved or embedded on the first chassis rod 111 or the second chassis rod 112 and is movably connected through a pin shaft, and the bottom end of the connecting top frame rod 133 is sleeved or embedded on the first top frame rod 131 or the second top frame rod 132 and is movably connected through a pin shaft. At this time, the position where the pin shaft is located is the rotation position.

[0040] Figure 3 The installation process schematic diagram of the gantry main body assembly 10 is shown, as Figure 2 shown, the installation process of the gantry main body assembly 10 of this solution is as follows:

[0041] The first step: Rotate the connecting chassis rod 113 to a position perpendicular to the first chassis rod 111 and the second chassis rod 112 and fix the rotation position;

[0042] The second step: Rotate the first vertical frame rod 121 to a position perpendicular to the first chassis rod 111 and fix the rotation position;

[0043] The third step: Rotate the first top frame rod 131 to a position perpendicular to the first vertical frame rod 121 and fix the rotation position;

[0044] The fourth step: Rotate the second vertical frame rod 122 to a position perpendicular to the second chassis rod 112 and fix the rotation position;

[0045] The fifth step: Rotate the second top frame rod 132 to a position perpendicular to the second vertical frame rod 122 and fix the rotation position;

[0046] The sixth step: Rotate the connecting top frame rod 133 to a position perpendicular to the first top frame rod 131 and the second top frame rod 132 and fix the rotation position.

[0047] It should be noted that the second step and the fourth step can be combined and carried out together, and the third step and the fifth step can also be combined and carried out together.

[0048] In addition, when the gantry main body assembly 10 is in the installation state, the tension rack 14 is fixedly connected between the top frame 13 and the bottom frame 11. To ensure the stability of the gantry fitness equipment, the tension rack 14 is arranged parallel and spaced relative to the vertical frame 12, that is, the vertical frame 12 and the tension rack 14 are both vertically connected between the top frame 13 and the bottom frame 11.

[0049] Further, the tension frame 14 includes a first tension frame 141 and a second tension frame 142, wherein the first tension frame 141 is fixedly connected between the first top frame body 131 and the first bottom frame body 111, and the second tension frame 142 is fixedly connected between the second top frame body 132 and the second bottom frame body 112.

[0050] Regarding the electronic resistance assembly 20 of this solution:

[0051] The electronic resistance assembly 20 of this solution is installed on the gantry main body assembly 10 to provide electronically adjustable electronic resistance. Specifically, the electronic resistance assembly 20 includes a resistance motor 21, a resistance adjuster 22 for adjusting the output resistance of the resistance motor 21, and a resistance output rope 23 connected to the output end of the resistance motor 21. One end of the resistance output rope 23 is connected to the output end of the resistance motor 21, and the other end is connected to the movable pulley group 31.

[0052] As Figure 5 shown, one end of the resistance output rope 23 is fixed on the output bearing of the resistance motor 21, and the resistance adjuster 22 is used to adjust the output resistance of the resistance motor 21, thereby providing different degrees of electronic resistance. In some embodiments, the resistance adjuster 22 is a potentiometer. At this time, the potentiometer is connected to the control circuit of the resistance motor 21. When the user rotates the potentiometer knob, the resistance value of the potentiometer will change, thereby outputting different voltage signals to the motor control circuit, and then adjusting the speed and torque of the motor to achieve stepless adjustment of the resistance. In other embodiments, the resistance adjuster 22 is a digital encoder. At this time, the resistance adjuster 22 and the motor controller of the resistance motor 21 are connected through a data bus. The digital encoder converts the user's adjustment signal into a digital signal and transmits it to the motor controller. The controller accurately controls the output resistance of the resistance motor 21 according to the received digital signal. This method has higher adjustment accuracy and stability, and can implement more complex adjustment functions, such as presetting different resistance modes, storing the user's personalized resistance settings, etc. In some embodiments, the electronic resistance assembly 20 is an electronic engine room, that is, the resistance motor 21, the resistance adjuster 22, and the resistance output rope 23 are all arranged in the electronic engine room and fixed on the gantry main body assembly 10.

[0053] Further, it should be noted that the gantry fitness equipment providing electronic resistance training in this solution can be linked with an APP or other intelligent devices. In some embodiments, the electronic resistance assembly 20 includes a Bluetooth module, which is used for communication connection with the APP or other intelligent devices to synchronize training data or remotely adjust the electronic resistance.

[0054] In some embodiments, the electronic resistance assembly 2 further has an overload protection mechanism. In some specific embodiments, a torque sensor and an emergency power-off module are provided in the electronic cabin. The torque sensor is used to sense the load of the resistance motor 21, and the emergency power-off module is used to control the conduction between the resistance motor 21 and the power supply. When the load of the resistance motor exceeds the rated load, the power supply of the resistance motor 21 can be automatically cut off. The gantry fitness equipment providing electronic resistance training in this solution further includes a cabin fixing frame 60 fixed on the chassis 11. A cabin accommodation space for accommodating the electronic resistance assembly 20 is formed in the cabin fixing frame 60, and an opening through which the resistance output rope 32 passes is provided on the cabin fixing frame 60. The resistance output rope 32 passes outwards through the opening on the cabin fixing frame 60 and is connected to the pulley assembly 30.

[0055] In some embodiments, the resistance output rope 23 is directly connected to the pulley assembly 30 to provide electronic resistance; in other embodiments, in order to make the acting force of the resistance output rope 23 act on the pulley assembly 30 stably, the resistance output rope 23 is connected to the pulley assembly 30 through a transfer pulley group.

[0056] As Figure 5 shown, a transfer pulley group 61 composed of at least one fixed pulley is provided on the cabin fixing frame 60, and the free ends of the resistance output rope 23 are respectively wound around the fixed pulleys and then connected to the pulley assembly 30. In a specific embodiment, the transfer pulley group 61 includes two fixed pulleys, and the resistance output rope 23 is sequentially wound around the two fixed pulleys and then connected to the pulley assembly 30. The advantage of such a setting is that the resistance output rope 23 can be stably connected to the pulley assembly 30 through the transfer pulley group 61, so that the resistance of the resistance output rope is transmitted to the pulley assembly more evenly and stably.

[0057] Regarding the pulley assembly 30 of this solution:

[0058] The pulley assembly 30 of this solution includes a movable pulley group 31 connected to the electronic resistance assembly 20 and a fixed pulley group 32 installed on the gantry main body assembly 10. The fixed pulley group 32 serves to change the turning direction of the pulling rope, and the movable pulley group 31 serves to provide pulling force training.

[0059] The movable pulley group 31 of this solution includes at least one guide rail 313 with two ends respectively connected to the electronic resistance assembly 20 and the gantry main body assembly 10, a movable pulley fixing block 311 slidably arranged on the guide rail 313, and a movable pulley 312 fixed in the movable pulley fixing block 311. The movable pulley fixing block 311 is connected to the resistance output rope 23 of the electronic resistance assembly 20, and the pulling rope is wound around the movable pulley 312 to pull the movable pulley fixing block 311 to move relative to the guide rail 313.

[0060] In some embodiments, the guide rail 313 is made of high carbon steel, with a T-shaped cross-section, and is matched with the ball bearings embedded in the movable pulley fixing block 311.

[0061] Specifically, the two ends of the guide rail 313 are respectively fixedly connected to the engine room fixing frame 60 and the connecting top frame member 133. The movable pulley fixing member 311 is connected to the transfer rope. At this time, when the pulling rope pulls the movable pulley 312 and drives the movable pulley fixing block 311 to move away from the electronic resistance assembly 20 on the guide rail, the pulling rope needs to overcome the electronic resistance of the electronic resistance assembly 20.

[0062] In some embodiments, a guide rail channel is provided on the movable pulley fixing block 312, and the guide rail 313 is passed through the guide rail channel so that the movable pulley fixing block 312 can move relatively on the guide rail.

[0063] In some embodiments, a buffer block is provided on the engine room fixing frame 60 at a position relative to the movable pulley fixing block 312. The advantage of this is to avoid damage caused by the movable pulley fixing block 312 colliding with the electronic resistance assembly 20 when the training pulling force suddenly relaxes.

[0064] In some embodiments, the opening on the engine room fixing frame 60 through which the transfer rope is passed is arranged directly opposite the central axis of the movable pulley fixing block 311. At this time, the transfer rope is connected to the central axis of the movable pulley fixing block 311 to ensure the stable transmission of the pulling force.

[0065] The setting of the steering fixed pulley group 32 in this solution serves to deflect the pulling rope, so as to guide the pulling rope on the pulling frame 14 to the position of the movable pulley group 31 to play a role in pulling force training.

[0066] In an embodiment of this solution, in order to cooperate with the disassembly and installation of the foldable gantry main body assembly of this solution, a first fixed pulley and a second fixed pulley are respectively provided at both ends of the top side of the first top frame body 131 of this solution, a third fixed pulley and a fourth fixed pulley are respectively provided at both ends of the top side of the second top frame body 132, a fifth fixed pulley and a sixth fixed pulley are respectively provided at both ends of the top side of the connecting top frame body 133, and a seventh fixed pulley and an eighth fixed pulley are provided at the connection position of the connecting top frame body 133 relative to the guide rail 313 at the middle position. The advantage of this setting is that when the connecting top frame body 133 is folded and stored relative to the first top frame body 131 or the second top frame body 132, the fixed pulleys on the top frame 13 will not interfere with each other.

[0067] In addition, a ninth fixed pulley and a tenth fixed pulley are respectively provided on the side surfaces of the first vertical frame body 121, and an eleventh fixed pulley and a twelfth fixed pulley are respectively provided on the side surfaces of the second vertical frame body 122, wherein the ninth fixed pulley and the tenth fixed pulley are connected by a connecting member, and the eleventh fixed pulley and the twelfth fixed pulley are connected by a connecting member.

[0068] In addition, a thirteenth fixed pulley and a fourteenth fixed pulley are respectively arranged at both ends of the top side of the first chassis body 111, and a fifteenth fixed pulley and a sixteenth fixed pulley are respectively arranged at both ends of the top side of the second chassis body 122. Among them, the thirteenth fixed pulley and the fifteenth fixed pulley are arranged on the back side of the tension frame 14, and the fourteenth fixed pulley and the sixteenth fixed pulley are arranged on the back side of the vertical frame 12.

[0069] In some embodiments, the pulleys in the movable pulley group 31 and the fixed pulley group 32 are all designed with nylon-coated bearing pulleys, thereby reducing the friction coefficient.

[0070] Of course, in order to ensure that the guiding force of the tension rope can be smoothly conducted, the fixed pulley located at the end side of the first top frame body 131, the fixed pulley assembly located on the side of the first vertical frame body 121, and the fixed pulley located at the end side of the first chassis body 111 are preferably arranged on the same side; similarly, the fixed pulley located at the end side of the second top frame body 132, the fixed pulley assembly located on the side of the second vertical frame body 122, and the fixed pulley located at the end side of the second chassis body 112 are preferably arranged on the same side.

[0071] Specifically, the ninth fixed pulley, the tenth fixed pulley, and the fourteenth fixed pulley are arranged on the back side of the first vertical frame body 121 relative to the tension frame 14. The ninth fixed pulley and the tenth fixed pulley are located on the same vertical axis, and the second fixed pulley is located above the ninth fixed pulley; the eleventh fixed pulley, the twelfth fixed pulley, and the sixteenth fixed pulley are arranged on the back side of the second vertical frame body 122 relative to the tension frame 14. The eleventh fixed pulley and the twelfth fixed pulley are located on the same vertical axis.

[0072] As Figure 4 shown, the wire routing method of the gantry fitness equipment for providing electric resistance training is as follows:

[0073] One end of the tension rope is connected to the tension handle 44, and the other end is successively connected to the first fixed pulley, the second fixed pulley, the ninth fixed pulley, the fifth fixed pulley, the seventh fixed pulley, the movable pulley, the eighth fixed pulley, the sixth fixed pulley, the eleventh fixed pulley, the fourth fixed pulley, and the third fixed pulley and then connected to the tension handle 14 on the other side. Specifically, the tension rope led out from the tension handle 44 on one side of the tension frame 14 successively passes through the upper side of the first top frame body 131, the back side of the first vertical frame body 121, the top side of the connecting top frame body 133 and then winds around the movable pulley. The tension rope extending from the other end of the movable pulley then successively passes through the top side of the connecting top frame body 133, the back side of the second vertical frame body 122, and the upper side of the second top frame body 132 and is connected to the tension handle 44 on the other tension frame 14 to form a tension rope path that can generate force on both sides.

[0074] In addition, after one end of the positioning rope located on one side is fixed to the tension member 40 on the first tension frame body 141, the other end passes through the thirteenth fixed pulley, the fourteenth fixed pulley, and the tenth fixed pulley in sequence and is fixed on the first bottom frame body 111; after one end of the positioning rope located on the other side is fixed to the tension member 40 on the second tension frame body 142, the other end passes through the fifteenth fixed pulley, the sixteenth fixed pulley, and the twelfth fixed pulley in sequence and is fixed on the second bottom frame body 121.

[0075] It should be noted that the length of the tension rope can be adjusted by setting the positioning ropes on both sides in this solution.

[0076] Regarding the tension assembly 40 of this solution:

[0077] Different from the traditional tension handle, the tension assembly 40 designed in this solution can realize tension training in multiple directions. Specifically, as Figure 6 shown, the tension assembly 40 of this solution includes a connecting member 41 sleeved outside the tension frame 14, a tension rope connecting member 43 rotatably connected to the connecting member 41, and a tension handle 44 connected to the tension rope connecting member 43 through a tension rope.

[0078] In order to realize multi-directional tension training, a rotating shaft is provided on the side of the connecting member 41 facing the tension rope connecting member 43, and the tension rope connecting member 43 is connected to the rotating shaft to realize multi-directional rotation. Specifically, two parallel ear plates are provided at intervals on the side of the connecting member 41, and a rotating shaft is fixed in the coaxial holes of the two ear plates by interference fit or snap ring to form a cantilever pivot structure, and the tension rope connecting member 43 is connected to the rotating shaft to realize multi-directional rotation of the tension rope connecting member 43.

[0079] Furthermore, since there are no obstacles on the side of the connecting body 41, the tension rope connecting member 43 can rotate 180° relative to the side of the connecting body 41, that is, the tension rope connecting member 43 can rotate to a position flush with the left side of the connecting body 41, or can rotate to a position flush with the right side of the connecting body 41.

[0080] In order to facilitate the adjustment of the installation position of the tension assembly 40, a plurality of positioning and installation holes are provided on the tension frame 14 of this solution, and connection holes matching the positioning and installation holes are provided on the connecting member 41. The connecting hole 41 is fixed to the tension frame 14 by passing a pull pin through the connection hole and the corresponding positioning and installation hole.

[0081] Furthermore, in order to realize the adjustment of multiple different heights of the tension assembly 40 at different heights, positioning and installation holes at different positions are provided on different sides of the tension frame 14 of this solution, and connection holes matching the positioning and installation holes are provided on multiple sides of the connecting member 41. The advantage of such a setting is that more height positioning can be realized through the cooperation of the positioning and installation holes and connection holes on different sides.

[0082] Specifically, the tension rack 14 is designed as a four-sided square column structure. Correspondingly, the connecting member 41 is also designed as a four-sided square column structure. One side of the connecting member 41 is connected to the tension rope connecting member, and connection holes matching the positioning and mounting holes are provided on the other three sides, so that the effect of positioning and mounting can be achieved on three sides.

[0083] Furthermore, due to the large tension during tension training, in order to protect the structure of the tension rack 14 from excessive wear during tension training, a buffer protection member is provided on the inner side wall of the connecting member 41 of this solution to buffer the acting force between the connecting member 41 and the tension rack 14. In the embodiment of this solution, the connecting member 41 is a four-sided square column structure. At this time, buffer protection members are provided at the four corners of the inner side wall of the connecting member 41, and the buffer protection members can be plastic parts.

[0084] As Figure 7 shown, in some embodiments, the tension rope connecting member 43 is designed as two spaced fixed pulleys, and one end of the tension rope is connected to the tension handle 44 and extends out from the gap between the two fixed pulleys. The advantage of this design is that it can ensure that the tension ropes on the tension rope connecting member 43 will not be entangled with each other.

[0085] In addition, the overhead fitness equipment providing electronic resistance training in this solution is additionally designed with a pull-up rack 50 provided on the top rack 13. As Figure 8 shown, both ends of the pull-up rack 50 are respectively fixed on the first top rack body 131 and the second top rack body 132 to provide a pull-up training method for the trainer.

[0086] Specifically, the pull-up rack 50 designed in this solution includes two parallel pull-up rack bodies 51. In some embodiments, the pull-up rack body 51 is designed as a structure with a flat middle and relatively inclined sides on both sides, that is, the middle end of the pull-up rack body 51 is designed as a parallel section parallel to the ground plane, and both sides are designed as relatively inclined inclined sections, so that the overall pull-up rack 50 presents a "bridge body" design shape.

[0087] In some embodiments, in order to reinforce the pull-up rack 50, the two parallel pull-up rack bodies 51 of the pull-up rack 50 are connected by a reinforcing member 52, and the reinforcing member 52 reinforces and connects the parallel sections on the pull-up rack body 51. Furthermore, in order to improve the stability of the reinforcement, both vertical and inclined reinforcing members 52 are provided between the two parallel pull-up rack bodies 51 to provide multi-faceted support bodies.

[0088] In some other embodiments, in order to provide a multi-functional training method, a hanging sandbag connector is provided between the two parallel pull-up rack bodies 51 of the pull-up rack 50.

[0089] It should be noted that the chin-up bar 50 of this solution is detachably installed on the top frame 13, and the chin-up bar 50 can be installed on the top frame 13 again when the trainer needs to use the chin-up bar 50.

[0090] Those skilled in the art should understand that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered that the scope recorded in this specification.

[0091] The above embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
