[0049] There are two first swing arms 21, two second swing arms 22 and two rocker arms 3 on the left and right sides. The two first swing arms 21 are respectively located on the left and right sides of the seat panel 11, and an operating rod 23 arranged in the left and right directions is installed between the two. The leg support roller 24 is installed between the two second swing arms 22.

[0050] The user sits at the front end of the bench panel 11 with his calves hanging down and pushing the leg support roller 24 from back to front, so that the second swing arm 22 swings forward and upward, pulling the first force transmission cable 61 more from the first force transmission winch 51, causing the first force transmission winch 51 to rotate, and the first resistance winch 53 rotating synchronously therewith reels in the first resistance cable 63, so that the first resistance cable 63 pulls the resistance spring 4, and the elastic force of the resistance spring 4 acts on the second swing arm 22 through the first resistance cable 63, the first resistance winch 53, the first force transmission winch 51 and the first force transmission cable 61 in turn, providing resistance for its forward and upward swinging, thereby realizing the training of the quadriceps femoris in the form of a kicking action.

[0051] The user lies on the bench panel 11 with his arms at the front end of the bench panel 11, holding the operating lever 23 or the first swing arm 21 and pushing it upward, so that the first swing arm 21 swings upward, and the second swing arm 22 moves upward accordingly, pulling the first force transmission cable 61 more out of the first force transmission winch 51, and the first force transmission winch 51 and the first resistance winch 53 rotate synchronously, and the retracted first resistance cable 63 pulls the resistance spring 4, and the elastic force of the resistance spring 4 acts on the first swing arm 21 through the second swing arm 22, providing resistance for its upward swinging, thereby realizing the training of the pectoral muscles in the form of a bench press action.

[0052] The user lies on the bench panel 11 with his legs located in the front part of the bench panel 11, and steps upward on the operating lever 23 or the first swing arm 21 to make the first swing arm 21 swing upward, and the first force transmission cable 61 is pulled out, and the first force transmission winch 51 and the first resistance winch 53 rotate synchronously, and the reeled first resistance cable 63 pulls the resistance spring 4, and the elastic force of the resistance spring 4 acts on the first swing arm 21 through the second swing arm 22, providing resistance for its upward swinging, thereby realizing the training of the leg and buttocks muscles by pushing the legs upward.

[0053] The user sits at the rear end of the bench panel 11, holds the rocker 3 and pushes it backwards to make the rocker 3 swing backwards, the first sprocket 31 rotates and causes the second sprocket 32 ​​to rotate via the chain 33, and the second resistance winch 54 rotates synchronously with the second sprocket 32 ​​to reel in the second resistance steel cable 64 to pull the resistance spring 4. The elastic force of the resistance spring 4 acts on the rocker 3 through the second resistance steel cable 64, the second resistance winch 54, the second sprocket 32 ​​and the first sprocket 31 in turn, providing resistance thereto, thereby achieving chest muscle training in the form of a chest push action.

[0054] The user sits at the rear end of the seat panel 11, holds the rocker 3 and pulls it forward to make the rocker 3 swing backward, and the first sprocket 31, the second sprocket 32 ​​and the second resistance winch 54 rotate synchronously, and the retracted second resistance steel cable 64 pulls the resistance spring 4. The resistance of the resistance spring 4 acts on the rocker 3 to provide resistance for it, thereby realizing the training of the back muscles by the backward pulling action.

[0055] Two rockers 3 are provided on the left and right sides so that both arms can be trained synchronously at the same time. Two first swing arms 21 are provided and connected by an operating rod 23 so that the two first swing arms 21 can swing synchronously, and the resistance is evenly distributed to the user's arms or legs, ensuring that both sides of the user's body can be fully exercised. Two second swing arms 22 are provided and connected by a leg support roller 24 so that the two second swing arms 22 can swing synchronously, and the resistance is evenly distributed to the user's legs, ensuring that both sides of the user's body can be fully exercised.

[0056] In the above-mentioned schematic embodiment, the bench-type comprehensive fitness machine realizes various training functions such as kicking, bench press, leg push, chest press, back pull, etc. by installing a first swing arm, a second swing arm and a rocker arm 3 on the bench body 1, and a resistance spring 4 provides resistance thereto through a steel cable, so as to realize strength training for different parts of the body, thereby improving the functionality of the fitness bench, having a wide range of applications and high training efficiency; the first swing arm can be stacked with the bench panel 11, the second swing arm can be close to the front side of the bench body 1, and only the rocker arm 3 extends upward to a certain extent. The first swing arm and the second swing arm will not extend outward relative to the bench body 1, and will not increase the space occupied in the length and width directions, so that the fitness machine has a smaller footprint, a compact structure, a simple structure, is suitable for a home environment with limited space, is easy to install and maintain, and solves the problem that the current fitness bench has a single function and the comprehensive fitness machine has a large size and a complex structure.

[0057] In some embodiments, a folding footrest 12 is installed at the rear end of the bench panel 11, a slide 13 is slidably installed on the bench panel 11, a second force transmission winch 52 is coaxially installed on the first sprocket 31, a second force transmission steel cable 62 wound on the second force transmission winch 52 is connected to the slide 13, and a handle 14 is provided on the slide 13.

[0058] The foldable foot pedal 12 is erected, and the user sits on the slide 13, holds the handle 14, and steps on the foldable foot pedal 12 to make the slide 13 slide forward, and the user's torso moves forward accordingly, and the user's legs gradually even out. In this process, the moving slide 13 pulls more of the second force transmission cable 62 out of the second force transmission winch 52, and the second force transmission winch 52 rotates, and the first sprocket 31 moves with it, and then the second resistance winch 54 is rotated through the chain 33 and the second sprocket 32, and the second resistance steel cable 64 is reeled in to pull the resistance spring 4. The elastic force of the resistance spring 4 acts on the slide 13 through the second resistance steel cable 64, the second resistance winch 54, the second sprocket 32, the first sprocket 31 and the second force transmission winch 52 in turn, providing resistance for the slide 13 to move backward, and training is performed in a manner similar to rowing, further increasing the functionality of the fitness device. In addition, the slide 13 is slidably installed on the bench panel 11, overlapped with the bench panel 11, and slides along the bench panel 11, does not extend out of the bench body 1, does not occupy height space and length space, and ensures the compactness of the fitness equipment structure.

[0059] In some embodiments, a plurality of rollers 15 are installed on both sides of the slide 13 , and the rollers 15 are slidably installed in a slide groove opened on a corresponding side of the bench panel 11 , so that the slide 13 can slide smoothly on the bench panel 11 .

[0060] The handle 14 is arranged vertically, and its bottom end is flush with the top end of the second force transmission winch 52. The second force transmission steel cable 62 is connected to the handle 14 so that the second force transmission steel cable 62 is connected to the handle 14 in a horizontal state. The direction of the resistance is parallel to the direction of movement of the slide 13, so that the resistance acts on the slide 13 to the maximum extent, thereby enhancing the effect of the user's impedance training.

[0061] In some embodiments, the resistance spring 4 is located in a horizontally arranged installation groove 16 in the stool body 1, and plugs 7 are installed at both ends of the resistance spring 4. The resistance spring 4 is a compression spring, and its elastic force presses the two plugs 7 onto the end face corresponding to one end of the installation groove 16.

[0062] The first resistance steel cable 63 passes over the first resistance guide wheel 55 installed at the front of the stool body 1 and is horizontally connected to the plug 7 at the rear end. The second resistance steel cable 64 passes over the second resistance guide wheel 56 installed at the rear of the stool body 1 and is horizontally connected to the plug 7 at the front end.

[0063] When the second swing arm 22 is raised or swung forward, the first force transmission cable 61 is pulled out, the first force transmission winch 51 and the first resistance winch 53 rotate synchronously, the first resistance cable 63 is retracted, the plug 7 at the rear end is pulled forward, the resistance spring 4 is compressed, and its elastic force acts as resistance to the second swing arm 22, thereby achieving resistance training. When the swing arm swings forward or backward, or the slide 13 slides, the second force transmission winch 52, the first sprocket 31, the second sprocket 32 ​​and the second resistance winch 54 rotate synchronously, the second resistance cable 64 is retracted, the plug 7 at the front end is pulled backward, the resistance spring 4 is compressed, and its elastic force acts as resistance to the swing arm and the slide 13, thereby achieving impedance training.

[0064] The resistance spring 4 realizes deformation in two directions through the plugs 7 at both ends, so that the front and rear moving parts (swing arm, rocker 3, slide 13) can achieve impedance training through the same resistance spring 4, without the need to set a separate resistance spring 4 for each moving part, reducing the number of parts and improving the compactness of the structure.

[0065] In some embodiments, when the rocker 3 is in a vertical state, one end of the second resistance steel cable 64 is fixedly connected to the wheel surface of the second resistance winch 54. Two limiting guide wheels 57 are installed at the rear of the stool body 1. After the second resistance steel cable 64 passes between the two limiting guide wheels 57, it is connected to the resistance spring 4. The two limiting guide wheels 57 clamp the second resistance steel cable 64.

[0066] Since the rocker 3 can swing forward or backward during strength training, the first sprocket 31 has two rotation directions, and the second resistance winch 54 also has two rotation directions accordingly. In the vertical state without force, the second resistance steel cable 64 is connected to the second resistance winch 54 at only one point, so that the second resistance winch 54 can smoothly reel in the second resistance steel cable 64 when rotating in both the forward and reverse directions, so that it pulls the resistance spring 4, ensuring that the rocker 3 can generate resistance for training in both directions. Since the second resistance steel cable 64 will deflect to one side when it is wound around the second resistance winch 54 in the forward and reverse directions, the two limit guide wheels 57 guide the second resistance steel cable 64 and support it when it deflects to one side, ensuring that it can be retracted and released smoothly in both the forward and reverse directions.

[0067] In some embodiments, Figures 2 to 3 As shown, there are multiple resistance springs 4, and multiple first resistance winches 53, second resistance winches 54, first resistance steel cables 63, and second resistance steel cables 64 are provided correspondingly.

[0068] At least one first resistance winch 53 is fixedly connected to the first axle 81 of the first force transmission winch 51 , and the other first resistance winches 53 are all sleeved on the first axle 81 and connected to the first transmission seat 85 provided on the first axle 81 through the first transmission pin 83 .

[0069] At least one second resistance winch 54 is fixedly connected to the second axle 82 of the second sprocket 32 ​​, and the remaining second resistance winches 54 are all sleeved on the second axle 82 and connected to the second transmission seat 86 provided on the second axle 82 through a second transmission pin 84 .

[0070] At least one resistance winch is fixedly connected to the axle, so that the first swing arm 21, the second swing arm 22, the rocker 3 and the slide 13 are connected to at least one resistance spring 4 in transmission, ensuring that there is resistance when the user operates the corresponding structure, which can play a role in impedance training. The resistance winch that is not fixedly connected is connected to the transmission seat of the corresponding axle through a transmission pin. Pulling out or plugging in the transmission pin can realize the disconnection or connection of the transmission between the resistance winch and the axle, so that by operating the transmission pin, the number of resistance winches connected to the axle can be changed, and then the number of resistance springs 4 that produce resistance to the first swing arm 21, the second swing arm 22, the rocker 3 and the slide 13 can be changed, so as to realize the adjustment of the user's training resistance.

[0071] In some embodiments, the first transmission pin 83 has a first transmission seat 85 on both sides, so that the first resistance winch 53 is located between the two first transmission seats 85, and the left and right ends of the first transmission pin 83 are both penetrated by the first transmission seat 85 on the corresponding side.

[0072] The second transmission pin 84 has a second transmission seat 86 on both sides thereof, so that the second resistance winch 54 is located between the two second transmission seats 86 , and the second transmission pin 84 has a second transmission seat 86 on the corresponding side penetrated at both ends thereof.

[0073] The resistance winch that can be installed with a transmission pin has transmission seats on both sides, so that the two transmission seats can limit it in the axial direction, so that the resistance winch is always located between the two transmission seats, thereby maintaining its axial position stable after the transmission pin is pulled out. When the transmission pin is installed again, the positional relationship between the resistance winch and the corresponding transmission seat is stable, which facilitates the transmission pin, the resistance winch and the corresponding transmission seat, ensuring convenient resistance adjustment operation.

[0074] In some embodiments, a limiting pin is inserted into the limiting seat 17 disposed at the front end of the bench panel 11 , and the limiting pin is inserted into the front end of the first swing arm 21 .

[0075] The first swing arm 21 is kept fixed by the limiting pin, so that when the user trains the quadriceps by kicking, only the second swing arm 22 moves, and its movement trajectory is stable, ensuring the effect of the corresponding training method.

[0076] In some embodiments, each of the first swing arms 21 is slidably mounted with a movable seat 25 , and both ends of the operating rod 23 are respectively connected to the corresponding movable seat 25 .

[0077] Since the chest muscles are trained in the bench press mode, the arm moves in the vertical direction. In the process of pushing the operating rod 23 upward, the first swing arm 21 swings upward, causing the movable seat 25 to slide toward the front end of the first swing arm 21, so that the operating rod 23 always remains vertically aligned with the arm, ensuring smooth bench press action.

[0078] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0079] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
