Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a butterfly push-pull integrated machine. Background Technology

[0002] The butterfly machine is a piece of equipment used for the "fly chest press," one of the many exercises in fitness activities. It is mainly used to work the pectoralis major and other chest muscles. Beginner users usually keep their backs close to the seat to exert force; more experienced users will lean away from the seat to work their abdominal muscles at the same time.

[0003] Many gyms now use weights on their butterfly machines to provide resistance. The weights on these weights range from 2.5 to 5 kilograms. Therefore, when adjusting the weights, you can only add or remove one weight unit at a time. This is not very user-friendly for people who want to do small-scale training, as it is difficult to match the appropriate load weight. Moreover, weight-based loading is quite common now, and it is troublesome for some beginners to add weights.

[0004] In addition, conventional butterfly machines only offer one exercise posture, limiting their effectiveness.

[0005] Therefore, how to provide a butterfly trainer with diverse and adjustable load training modes is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the present invention provides a butterfly push-pull integrated machine, which has a simple structure, is easy to use, has a variety of exercise postures and exercise modes to choose from, and is not limited to chest clamping exercises, chest expansion exercises, double arm push-pull exercises, etc. It has a wide range of applications and is easy to promote and use.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a butterfly push-pull integrated machine, comprising:

[0008] A pedestal, wherein a support frame is fixed in the middle of the pedestal, and a multi-directional adjustable seat is provided on one side of the pedestal corresponding to the support frame;

[0009] A wobbling load assembly is rotatably mounted on the support frame or the pedestal, and a drive shaft is horizontally fixedly connected to the bottom side of the wobbling load assembly, through which the wobbling damping of the wobbling load assembly is transmitted.

[0010] A transmission rod system, which is rotatably mounted on the pedestal and / or support frame, and the transmission rod system consists of two sets symmetrically distributed on both sides of the wobbling load assembly;

[0011] The horizontal rocker arm has two sets and is respectively arranged on one side of the corresponding support frame of the pedestal. The horizontal rocker arm is connected to the drive shaft through the corresponding side transmission rod system. The horizontal rocker arm provides the user with chest expansion training.

[0012] The longitudinal rocker arm has two sets, which are detachably connected to the two outer sides of the base near the wobbling load assembly. The longitudinal rocker arm is connected to the drive shaft and enables the user to perform push-pull training with both arms.

[0013] The beneficial technical effects of this utility model are as follows: The pedestal provides the load-bearing foundation for the entire training equipment, ensuring stable placement and providing a stable training environment for personnel. The wobbling load component provides training damping for personnel training. The support frame effectively divides the pedestal into two areas, one of which mainly houses the multi-directional adjustable seat. The wobbling load component can be placed in the other area or on top of the support frame. The multi-directional adjustable seat can be adjusted to a comfortable position according to the user's needs. The horizontal rocker arm is connected to the transmission shaft via a transmission rod system, and the vertical rocker arm is installed according to training needs, directly connected to both ends of the transmission shaft. The horizontal and vertical rocker arms provide users with different exercise postures or situations, thereby completing the training of muscles in the limbs, arms, chest, back, and shoulders. This equipment changes the traditional weight-bearing load mode and instead provides training resistance and wobbling damping based on the seesaw principle. The wobbling resistance of the wobbling load component provides training damping for the user, thereby achieving the ideal training effect.

[0014] Preferably, the wobbling load assembly includes a wobbling housing, a load sliding frame, a metal counterweight, and a sliding frame travel limiting mechanism. The drive shaft is fixedly connected to the bottom center of the wobbling housing. The wobbling housing has a rectangular structure and an open top. The load sliding frame slides inside the wobbling housing. A limiting plate is detachably connected to the outside of the load sliding frame. The metal counterweight is detachably connected to the load sliding frame and cooperates with the load sliding frame to provide the wobbling load of the wobbling housing. The sliding frame travel limiting mechanism is located in the middle of the wobbling housing and is used to limit the overstepping state of the limiting plate.

[0015] The resulting technical effect is that the swaying load assembly provides training damping for personnel training, based on the movement of the load sliding frame and metal counterweight within the swaying box. The swaying damping can be linearly variable. The sliding frame travel limit mechanism can restrict the sliding stroke of the load sliding frame within the swaying box. The sliding stroke of the load sliding frame within the swaying box can be adjusted based on the presence or absence of an upper limit plate. With the upper limit plate, the load sliding frame can reciprocate within half its stroke within the swaying box, based on the sliding frame travel limit mechanism. Without the upper limit plate, the load sliding frame can reciprocate within its full stroke within the swaying box. This provides the possibility for adjusting different training modes, such as individual chest fly exercises, individual chest expansion exercises, or other push-pull force training.

[0016] Preferably, it also includes a clamping member for positioning the load sliding frame within the rocker box. When the load sliding frame is positioned at the end of the rocker box using the clamping member, the trainer has a full resistance training mode.

[0017] The resulting technical effect is that the clamping device positions the load sliding frame at the end of the tilting box, preventing the metal counterweight from moving towards the middle of the tilting box. In this case, the load resistance can be fully utilized, which makes the full resistance training mode of the trainer possible. The purpose of the clamping device is to position the load sliding frame at the end of the tilting box, not to fix it. The load sliding frame may have vertical displacement changes.

[0018] Preferably, the sliding frame travel limiting mechanism includes an inertia disk, pressing claws, actuating pins, and horn blocks. The inertia disk is rotatably connected to the middle of the outer side wall of the rocker housing. Two sets of pressing claws are fixed to the lower two sides of the inertia disk. The pressing claws are located on the lower side of the rocker housing. The bottom wall of the rocker housing can act on the corresponding pressing claws and cause the inertia disk to rotate by an angle. The middle side wall of the rocker housing is provided with a clearance arc groove. The horn blocks are arranged in pairs and rotate at a certain angle on the inner side wall of the rocker housing. The rocker housing is close to the two horn blocks. A limit stop pin is fixed on the outer side of the corner block. The limit stop pin is used to limit the downward rotation stroke of the corner block. The group of corner blocks are distributed at both ends of the avoidance arc groove and are used to limit the limit plates on both sides of the load sliding frame from passing over. The top two sides of the inertia plate are provided with two actuation pin mounting holes. The actuation pin can be detached and connected to either of the actuation pin mounting holes. The actuation pin can pass through the avoidance arc groove and actuate the corner block on the nearby side. The deflection of the corner block can release the sliding restriction on the limit plate and cause the load sliding frame to slide towards the lower end of the rocker box.

[0019] The resulting technical effect is as follows: This device uses an inertial disc, a pressing claw, a lever pin, and a horn block to restrict the sliding of the limiting disc, thereby controlling the sliding of the load sliding frame. It can be understood that when the rocker box tilts downwards from a horizontal position, at a certain angle, the bottom wall of the rocker box contacts the pressing claw, causing the inertial disc to rotate. Simultaneously, due to the rotational inertia of the inertial disc, the lever pin can rotate downwards relative to the load sliding frame and deflect it against the horn block. The limiting disc slides out from the horn block on that side, thus enabling the load sliding frame to slide towards the lower end of the rocker. Similarly, when the rocker box tilts upwards from the lower end, the load sliding frame will slowly slide towards the middle of the rocker box. The limiting disc of the load sliding frame can only slide between the two horn blocks and cannot slide forward further. The downward rotation angle of the horn block is limited by the limiting stop pin, allowing it to only pass through in one direction. When the limiting disc slides in the opposite direction, the horn block needs to be levered to release the restriction.

[0020] In addition, the toggle pin only needs to be installed in one toggle pin mounting hole according to the exercise mode. This is a prerequisite for ensuring that the limit plate of the load sliding frame slides to stop between the two bullhorn blocks.

[0021] Preferably, the bottom wall of the rocking box is provided with ejector slots at both ends, and the inner bottom wall of the rocking box is provided with magnets at both ends. The metal counterweight can be attracted to the magnet on the closer side. Two sets of abutting mechanisms are staggered on the bottom side of the rocking box. When the rocking box is rocking, one end of the abutting mechanism is slidably connected to the bottom wall of the rocking box, and the other end pushes the metal counterweight through the ejector slot on the corresponding side and causes the metal counterweight to pull away from the magnet on the closer side.

[0022] The resulting technical effect is as follows: In order to prolong the damping effect of the tilting box during training and prevent the load sliding frame and metal counterweight from sliding rapidly and losing their training effect when the tilting box is tilted, a magnet is installed so that the magnet and the metal counterweight have an attraction effect. At the same time, a pushing mechanism is used to push the metal counterweight and the magnet to create a distance. In this way, under the action of gravity, the load sliding frame and the metal counterweight can slide with gravity. The magnetic attraction between the magnet and the metal counterweight, combined with the pushing mechanism, can achieve a delayed sliding response of the load sliding frame, thereby ensuring the training effect.

[0023] Preferably, the abutting mechanism includes an L-shaped lever, a rotating wheel, an ejector bracket, and a pushing wheel. The hinge fulcrums of the two L-shaped levers are staggered on both sides of the transmission shaft. The rotating wheel rotates at one end of the short shaft of the L-shaped lever. The ejector bracket is fixed at the other end of the long shaft of the L-shaped lever. The long shaft ends of the two L-shaped levers are distributed near the two ends of the rocker box. The pushing wheels are paired up and rotatably connected to the ejector bracket. The pushing wheels can pass through the ejector slot to push the metal counterweight.

[0024] The resulting technical effect is that the jacking mechanism, in coordination with the rocking box, is a process of adaptively jacking the metal counterweight. Since the L-shaped lever has a long axis end and a short axis end, and its rotation center is offset from the output shaft, the long axis end of the L-shaped lever has a displacement greater than that of the rocking box. It can be understood that at the high position of the rocking box, the long axis end of the L-shaped lever can achieve the jacking effect of the metal counterweight through the push-out bracket and the jacking wheel. The jacking wheel can be a PU wheel or a rubber wheel.

[0025] Preferably, the inner walls at both ends of the rocker box are provided with buffer pads for buffering the load sliding frame and the metal counterweight. One end of the load sliding frame can contact the buffer pad, and the other end of the load sliding frame is detachably connected to a trailer box. The trailer box is provided with a counterweight bracket, and the counterweight bracket is detachably connected to a counterweight positioning plate. The counterweight positioning plate can be restricted between the group of horn blocks.

[0026] The resulting technical effect is that the installation and placement of the tilting box are directionally limited. Based on different training modes, it is always necessary to ensure that the impact side of the load sliding frame and the metal counterweight is in contact with the buffer pad on the tilting box to buffer the force. In other words, when training begins, the metal counterweight is at the buffer pad end and (regardless of whether clamps are used) requires 100% force. The set towing box and counterweight positioning plate can adjust the load sliding frame and the metal counterweight to slide to a position near the middle of the tilting box, thereby changing the degree of passive force during the recovery action. If the force is too great, it may cause training injury to the user; if the force is too small, it will lose its training significance.

[0027] Due to the limitations of the trailer and the counterweight positioning plate, the overall counterweight slides in the half-stroke of the tilting box. In this case, the load sliding frame and the metal counterweight block are always on one side of the tilting box. In this way, there is always a passive force exertion process during the motion recovery control process, but the force exertion is not 100% and will be reduced by several percent to adapt to the rehabilitation training mode.

[0028] In practice, when users initiate chest-clamping, chest-expanding, and pushing-pull movements, they will actively exert force 100%. The passive force exertion during the recovery movement will be adjusted according to the settings of the trailer and the weight positioning plate to adapt to different training mode requirements.

[0029] Preferably, the two sides of the platform are provided with perforated plates that limit the travel range of the longitudinal rocker arm. The longitudinal rocker arm reciprocates at a certain angle and is located within the travel limiting hole of the perforated plate. The longitudinal rocker arm is connected to the drive shaft through gear transmission.

[0030] The resulting technical effect is that the orifice plate limits the maximum reciprocating stroke range of the longitudinal rocker arm, improving the safe use of the training equipment.

[0031] Preferably, an external seat is detachably connected to the other side of the support frame corresponding to the pedestal, and the two sides of the pedestal are provided with pedals for users to step on.

[0032] The resulting technical effect is that when using the longitudinal rocker arm swing exercise, a seat can be detached and connected to the platform. The seat can be a multi-directional adjustable seat with forward and backward movement function, which is convenient for exercising the shoulder and arm muscles in a seated position. In addition, the seat can be removed and the limb and arm push and pull exercises can be performed directly on the pedal.

[0033] Preferably, the transmission rod system is connected to the corresponding end of the transmission shaft via a right-angle planetary gear reducer, the reduction ratio of the right-angle planetary gear reducer is 5:1, and when the lateral rocker arm performs a 90° chest expansion exercise, the wobbling load component has a wobbling angle of 18°; the longitudinal rocker arm is mounted on the output shaft of the planetary gear reducer, or the longitudinal rocker arm is connected to the output shaft of the right-angle planetary gear reducer via a crank-rocker mechanism.

[0034] The resulting technical effects are as follows: a right-angle planetary gear reducer can be added to the transmission, which allows the lateral rocker arm to have a smaller wobbling angle during normal, large-amplitude chest expansion exercises. At the same time, in order not to affect the pushing and pulling range of the longitudinal rocker arm, a crank-rocker mechanism can be added for transition transmission. The crank-rocker mechanism is used to fix the longitudinal rocker arm to the crank, while fixing the rocker arm to the output shaft of the right-angle reducer. In this way, the wobbling housing has a smaller wobbling range, while the longitudinal rocker arm has a larger range of motion, thus ensuring that the arm can complete flexion and extension during pushing and pulling exercises.

[0035] Preferably, a platform is provided on the top of the support frame and on the side near the multi-directional adjustable seat. Arc-shaped adjustment holes are provided at both ends of the platform. One end of the transverse rocker arm is detachably connected to a transition force transmission assembly, which includes a sleeve, a step, a flange nut, and a gear shaft. The sleeve slides within the arc-shaped adjustment hole. The step is located on the top outer side of the sleeve and abuts against the top surface of the platform. The flange nut is threaded to the bottom of the outer wall of the sleeve and abuts against the bottom surface of the platform. The position of the sleeve within the arc-shaped adjustment hole is positioned by adjusting the tightness of the flange nut. The gear shaft is rotatably mounted inside the sleeve via a bearing. The gear shaft and the vertical shaft of the transmission rod system are driven by gear meshing. One end of the transverse rocker arm is detachably connected to the gear shaft, and the other end of the transverse rocker arm serves as a gripping end and provides a gripping base for the user.

[0036] The resulting technical effect is that the design of the transition force transmission component makes it possible to adjust the distance between the two horizontal rocker arms. The distance between the two horizontal rocker arms can be adjusted according to actual needs to accommodate people of different body types, thus improving the versatility of the equipment.

Detailed Implementation

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0054] See appendix to this utility model Figures 1 to 15 According to an embodiment of the present invention, a butterfly push-pull integrated machine includes:

[0055] The platform 1 has a support frame 2 fixed in the middle. A multi-directional adjustable seat 3 is provided on one side of the platform 1 corresponding to the support frame 2. In actual use, it can be a manual multi-directional adjustable seat or an electric multi-directional adjustable seat. The position can be moved and a single seat can be used in multiple exercise modes. Adjustments can be made according to usage needs.

[0056] The wobbling load assembly 4 is rotatably mounted on the other side of the support frame 2 corresponding to the base 1. A transmission shaft 5 is horizontally fixedly connected to the bottom side of the wobbling load assembly 4 and transmits the wobbling damping of the wobbling load assembly 4 through the transmission shaft. The training damping is achieved based on the wobbling of the wobbling load assembly. The wobbling load assembly 4 can also be directly arranged on the top of the support frame 2 to make full use of the component space layout.

[0057] The transmission rod system 6 is rotatably mounted on the base 1 and the support frame 2. There are two sets of transmission rod systems 6, symmetrically distributed on both sides of the wobbling load assembly 4. One end of the transmission rod system 6 is connected to the transmission shaft 5, and the other end extends above the support frame 2. This transmission rod system provides the basis for the transmission layout of the transverse rocker arm 7. It should also be noted that, based on the arrangement direction of the meshing bevel gears, the rotation directions of the two vertical shafts of the two transmission rod systems are opposite, enabling the subsequent chest-opening and squeezing movements of the transverse rocker arm 7. This is also key to butterfly-style chest-opening and squeezing exercises. For the transmission principle of the transmission rod system, please refer to the appendix. Figure 15 ;

[0058] Besides the two-shaft transmission configuration, another implementation of the transmission system is a single vertical shaft transmission, which directly transfers the torque from the transmission shaft to the horizontal rocker arm. See the appendix for the principle. Figure 14 In specific implementation, the transmission rod system 6 is connected to the corresponding end of the transmission shaft 5 through a right-angle planetary gear reducer. The reduction ratio of the right-angle planetary gear reducer is 5:1. When the transverse rocker arm 7 performs 90° chest expansion training, the wobbling load component 4 has a wobbling angle of 18°. The longitudinal rocker arm 8 is located on the output shaft of the planetary gear reducer, or the longitudinal rocker arm 8 is connected to the output shaft of the right-angle planetary gear reducer through a crank rocker mechanism.

[0059] The crank-rocker mechanism is used by fixing the longitudinal rocker arm to the crank, while fixing the rocker to the output shaft of the right-angle reducer. In this way, the rocker housing has a small rocking amplitude, while the longitudinal rocker arm has a large range of motion, thus ensuring that the arm can complete flexion and extension during push-pull exercises.

[0060] Regardless of the transmission method, it is necessary to ensure that the swing arm has a large displacement range, while the wobbling box has only a small displacement range, so as to ensure that the user has sufficient training stroke range.

[0061] The horizontal rocker arm 7 has two sets and is arranged on one side of the corresponding support frame of the base 1. The horizontal rocker arm 7 is connected to the other end of the transmission rod system on the corresponding side to realize the user's chest expansion training.

[0062] The longitudinal rocker arm 8 has two sets and is detached and arranged on the other side of the support frame corresponding to the base 1. When training with the butterfly machine, there is no need to set up the longitudinal rocker arm. The longitudinal rocker arm 8 is connected to the drive shaft 5 and realizes the user's double arm push-pull training.

[0063] Instructions for disassembling and connecting the longitudinal rocker arm 8: The longitudinal rocker arm 8 is connected to the gear shaft through a hexagonal hole. The end edge of the gear shaft has a hexagonal shaft section. The fit between the hexagonal shaft and the hexagonal hole facilitates torque transmission. Then, the nut is connected to the end of the gear shaft, or a retaining pin is used for connection.

[0064] In other embodiments, the wobbling load assembly 4 includes a wobbling housing 41, a load sliding frame 42, a metal counterweight 43, and a sliding frame travel limit mechanism 44. The drive shaft 5 is fixedly connected to the middle of the bottom side of the wobbling housing 41. The wobbling housing 41 has a rectangular structure and its top side is open. The load sliding frame 42 is slidably located inside the wobbling housing 41. A limit plate 421 is detachably connected to the outside of the load sliding frame 42. The metal counterweight 43 is detachably connected to the load sliding frame 42 and cooperates with the load sliding frame to provide the wobbling load of the wobbling housing 41. The metal counterweights can be stacked one by one on the load sliding frame as needed.

[0065] The sliding frame travel limit mechanism 44 is located in the middle of the rocker box 41 and works with the limit plate 421 to limit the sliding travel of the load sliding frame 42 and the metal counterweight 43 in the rocker box.

[0066] When the limit plate 421 is in place, based on the setting of the sliding frame stroke limit mechanism 44, the load sliding frame 42 and the metal counterweight 43 can complete half-stroke sliding in the tilting box, avoiding continuous force training of chest clamping and chest expansion. When the load sliding frame 42 slides carrying the metal counterweight 43, the tilting damping generated by the tilting box is changing, which can provide users with a better training experience.

[0067] When the unlimited position plate 421 is in place, the load sliding frame 42 and the metal counterweight 43 can complete the full stroke sliding in the tilting box. This situation is suitable for push-pull active force training.

[0068] When the reference position is determined, the two horizontal rocker arms 7 are parallel, and the rocker box 41 is horizontal. To perform chest compression exercises, place the load sliding frame 42 and the metal counterweight 43 on one side of the rocker box and slide it halfway. To perform chest expansion exercises, place the load sliding frame 42 and the metal counterweight 43 on the other side of the rocker box and slide it halfway.

[0069] In another training mode, the load sliding frame 42 and the metal counterweight 43 can be directly positioned on the end of the rocker box using clamping devices 16. These clamping devices are either leech pins or door-shaped pins. The clamping devices are fixed to the rocker box, only positioning the load sliding frame at the end of the rocker box to prevent it from moving towards the center. Simultaneously, the leech pins do not affect the up-and-down movement of the load sliding frame, avoiding the influence of the subsequent counter-balancing mechanism 9. In this mode, during chest clamping, chest expansion, and push-pull training, active force is 100%, and controlled force during recovery is also 100%. For example, during chest clamping, the active force for lifting the weight is 100%, and the passive force for recovery is also 100%. (See attached diagram). Figure 11 .

[0070] In other embodiments, the sliding frame travel limiting mechanism 44 includes an inertia disk 441, a pressing claw 442, a lever pin 443, and a horn block 444. The inertia disk 441 is rotatably connected to the middle of the outer side wall of the rocker housing 41. There are two sets of pressing claws 442, which are fixed to the lower two sides of the inertia disk 441. In the reference position, the pressing claws 442 are located on the lower side of the rocker housing 41, but not tightly attached, with a certain gap, so that the inertia disk 441 has a certain rotational inertia. The bottom wall of the rocker housing 41 The pressure claw 442 can act on the corresponding side and cause the inertial disk 441 to rotate by an angle. The middle side wall of the rocker box 41 is provided with a clearance arc groove 411. The bull horn blocks 444 are grouped in pairs and rotated at a certain angle on the inner side wall of the rocker box 41. The rocker box 41 is fixed with a limit stop pin 445 near the outer side of the two bull horn blocks. The limit stop pin 445 is used to limit the downward stroke of the bull horn blocks 444. It should be noted that the limit stop pin 445 is installed diagonally below the rotation point of the bull horn blocks.

[0071] Groups of bullhorn blocks 444 are distributed at both ends of the clearance arc groove 411 and are used to restrict the limit plates 421 on both sides of the load sliding frame 42 from passing over. The actuating pin 443 is detached from the inertia plate 441 and can pass through the clearance arc groove 411 to actuate the bullhorn blocks 444 on the near side. The deflection of the bullhorn blocks 444 can release the sliding restriction on the limit plates 421 and cause the load sliding frame 42 to slide towards the lower end of the rocker box 41.

[0072] In another feasible scenario, the bull horn block 444 and the limiting pin 445 are fixed on the external frame. The bull horn block is located on the movement path of the limiting plate and can complete the stroke limit of it. In this case, the inertial plate deflects with the rocker box to complete the movement of the bull horn block 444.

[0073] Regarding the load sliding frame, rollers are installed on both sides of the load sliding frame. The inner wall of the rocker box has a central rail, or it may not. The bottom rollers support the movement of the load sliding frame. There is a vertical gap between the central rail and the bottom rollers to allow for vertical movement of the load sliding frame. The bottom rollers are tumblingly connected to the bottom wall of the rocker box. The limit plate 421 is located above the central rail (when there is a central rail) and realizes simple sliding control of the load sliding frame. In order to reduce the interference of the horn block on the limit plate 421, one limit plate 421 can be set on each side of the load sliding frame.

[0074] In some other embodiments, the top two sides of the inertial disk 441 are provided with two toggle pin mounting holes. Depending on the training mode requirements, the toggle pin 443 can be detached and connected to the toggle pin mounting hole on the corresponding side.

[0075] It is understandable that the installation of the actuating pin 443 on the inertia disk is based on the sliding position of the load sliding frame 42. The actuating pin 443 needs to be installed on the side of the inertia disk that is close to the load sliding frame 42 for reciprocating sliding. The purpose is to effectively realize the deflection and actuation of the horn block on that side, so as to release the sliding restriction on the upper limit plate 421 of the load sliding frame.

[0076] In other embodiments, both ends of the bottom wall of the rocker box 41 are provided with ejection slots 412, and both ends of the inner bottom wall of the rocker box 41 are provided with magnets 413. The metal counterweight 43 can be attracted to the magnet 413 on the side closer to it. It should be noted that this is not a complete attraction, and there may be a gap. Based on the attraction between the magnets, the counterweight metal block has a certain displacement restriction effect when it is at one end of the magnet.

[0077] Two sets of abutting mechanisms 9 are staggered on the bottom side of the rocking box 41. When the rocking box 41 rocks, one end of the abutting mechanism 9 slides with the bottom wall of the rocking box 41, and the other end pushes the metal counterweight 43 through the ejection slot 412 on the corresponding side and causes the metal counterweight 43 to pull away from the magnet 413 on the nearby side. The magnetic attraction force is reduced, so that the load sliding frame slides to a lower position under the action of gravity.

[0078] In some other embodiments, the abutting mechanism 9 includes an L-shaped lever 91, a rotating wheel 92, an ejector bracket 93, and an ejector wheel 94. The hinge points of the two L-shaped levers 91 are staggered on both sides of the transmission shaft 5. The rotating wheel 92 is rotatably located at one end of the short shaft of the L-shaped lever 91. The ejector bracket 93 is fixed at the other end of the long shaft of the L-shaped lever 91. The long shaft ends of the two L-shaped levers are distributed near the two ends of the rocker box 41. The ejector wheels 94 are paired together and rotatably connected to the ejector bracket 93. The ejector wheels 94 can pass through the ejector slot 412 to abut the metal counterweight 43.

[0079] Understandably, when the rocking box 41 is rocking, only one of the two rocking mechanisms 9 completes the rocking action.

[0080] In some other specific embodiments, the inner walls of both ends of the rocker box 41 are provided with buffer pads 414 for buffering the impact of the load sliding frame 42 and the metal counterweight 43. One end of the load sliding frame 42 can contact the buffer pad 414, and the other end of the load sliding frame 42 is detachably connected to the trailer box 10. The trailer box 10 is provided with a counterweight bracket 101. The counterweight bracket 101 is detachably connected to the counterweight positioning plate 102. The counterweight positioning plate 102 can be restricted between the groups of horn blocks 444.

[0081] When the trailer box 10 and its counterweight positioning plate 102 are present, the load sliding frame 42 and the metal counterweight block 43 will not slide to the exact center of the rocker box 41, but will slide to a stop near the center of the rocker box 41. The presence or absence of the trailer box 10 and the setting of the counterweight positioning plate 102 are used to adjust the passive force of the recovery control and the sliding stroke state of the weight block (half stroke sliding or full stroke sliding) to adapt to different training mode requirements.

[0082] Of course, in another training mode, the load sliding frame 42 can also be clamped with a clamp to fix it to the end of the tilting box 41 (to prevent the weight from sliding down to a lower position), so as to achieve 100% active force exertion and 100% passive force exertion through recovery control.

[0083] Specifically, based on the arrangement of the trailer box 10 and its counterweight positioning plate 102, the load sliding frame 42 and the metal counterweight block 43 are stopped at the middle position of the tilting box 41, thereby reducing the force of the recovery control and avoiding the loss of training significance due to insufficient recovery control force.

[0084] There is a gap between the trailer box 10 and the bottom wall of the rocker box 41 to avoid interference with the end magnet.

[0085] In other embodiments, the two sides of the base 1 are provided with perforated plates 11 that limit the travel range of the longitudinal rocker arm 8, and the longitudinal rocker arm 8 is located within the perforated plates 11.

[0086] In some other embodiments, the pedestal 1 has multiple uprights 13 on both sides near the wobbling load assembly 4. The uprights 13 are used for detaching and connecting the external seat 14. A footrest 12 for the user to step on is provided on the pedestal and on the outside of the multiple uprights. The user can choose a suitable exercise posture as needed. (Refer to the attached diagram.) Figure 12 .

[0087] In other embodiments, a platform 21 is provided on the top of the support frame 2 and on the side near the multi-directional adjustable seat 3. Arc-shaped adjustment holes 22 are provided at both ends of the platform. The center of the arc-shaped adjustment holes 22 is the vertical shaft of the transmission rod system. One end of the transverse rocker arm 7 is detachably connected to a transition force transmission assembly 15. The transition force transmission assembly 15 includes a sleeve 151, a step 152, a flange nut 153, and a gear shaft 154. The sleeve 151 slides within the arc-shaped adjustment hole 22. The step 152 is located on the top outer side of the sleeve 151 and abuts against the top surface of the platform 21. The flange nut 153 is threaded... The sleeve 151 is attached to the bottom of the outer wall of the sleeve 151 and can abut against the bottom surface of the plate 21. The position of the sleeve 151 in the arc-shaped adjustment hole 22 is positioned by adjusting the tightness of the flange nut 153. The gear shaft 154 is rotatably mounted inside the sleeve 151 through the bearing. The gear shaft 154 and the vertical shaft of the transmission rod system 6 are driven by gear meshing. The gear is connected to the gear shaft 154 by a key. The two ends of the gear can be sandblasted to increase the coefficient of friction. One end of the transverse rocker arm 7 is detachably connected to the gear shaft 154, and the other end of the transverse rocker arm 7 is the grip end and provides a grip base for the user.

[0088] One end of the horizontal rocker arm 7 is provided with a connecting sleeve, which passes through the outside of the gear shaft 154. The connecting sleeve is provided with an adjusting bolt. The relative rotation between the horizontal rocker arm 7 and the gear shaft 154 is limited by the tightness of the adjusting bolt against the outer wall of the gear shaft. Of course, the position of the connecting sleeve on the gear shaft 154 can also be adjusted up and down for easy adjustment by the user.

[0089] Description of the movement of the load-bearing sliding frame:

[0090] The system features a half-stroke sliding mode with a trailer box and a counterweight positioning plate. When one end of the trailer box tilts from a low position to a high position, the load sliding frame on that side slides under gravity. When the counterweight positioning plate slides to the first horn block on the side, it pushes the horn block upwards, thus passing over it. Due to the limiting pin on the outer side of the second horn block, the downward rotation angle of the second horn block is limited, meaning the counterweight positioning plate cannot pass over the second horn block. (There is no actuating pin to move the second horn block here.) The corner block stops the trailer in the middle of the rocker box. When one end of the rocker box descends from a high position to a low position, the bottom wall of the rocker box contacts the pressing claw, which in turn drives the inertial disk to rotate. At the same time, the actuating pin on this side can press against the corner block. The actuation of the corner block provides the condition for the counterweight positioning plate to pass through this side. The counterweight positioning plate slides out from the corner block on this side, thus realizing the process of the load sliding frame sliding towards the lower end of the rocker box. By repeating the cycle, individual chest clamping or chest expansion training can be completed.

[0091] The full-stroke sliding mode without a trailer box and counterweight positioning plate: In this mode, the limiting plates on both sides of the load sliding frame are removed. When one end of the tilting box tilts from a low position to a high position, the load sliding frame on that side slides under the action of gravity. The load sliding frame smoothly passes through the two bullhorn blocks to the other end. In other words, in this case, the sliding frame stroke limiting mechanism does not work, and the load sliding frame can slide in the tilting box for the full stroke. This situation is suitable for training of limb pushing and pulling force.

[0092] Of course, depending on different training needs, the trailer box and its counterweight positioning plate can be reasonably set to achieve the change of the overall weight block half-stroke sliding and full-stroke sliding.

[0093] The core principle of this solution is to use the rocking motion of the rocking box to provide training damping, thereby providing training such as chest clamping, chest expansion, and push-pull exercises. In specific implementation, the rocking box is not limited to the position on the pedestal, but can also be on the support frame. Similarly, the core of the transmission system is to connect the torque transmission between the transmission shaft and the swing arm. It is not limited to the specific form of the components. Single shafts or multiple shafts are all acceptable, and the arrangement can be based on actual needs. Helical planetary reducers can also be added at the transmission joints as needed to reduce torque transmission errors, etc.
