[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] like Figures 1 to 11 As shown, in an illustrative embodiment of the multifunctional fitness machine of the present invention, the multifunctional fitness machine includes a frame 1, a weight unit 2 and a training unit 3.

[0054] The weight unit 2 includes a weight piece 21 , which is slidably mounted on a guide rail 11 vertically arranged at the rear side of the frame 1 so as to be able to rise and fall to provide resistance for the training unit 3 .

[0055] The front side of the frame 1 is a gantry 12 , and the training unit 3 is connected to the counterweight unit 2 via a steel cable 4 .

[0056] The training unit 3 includes a first training mechanism 31 , a second training mechanism 32 , a third training mechanism 33 and a fourth training mechanism 34 , and the steel cable 4 includes a first steel cable 41 , a second steel cable 42 , a third steel cable 43 and a fourth steel cable 44 .

[0057] The first training mechanism 31 includes a handle 311 and a guide wheel 312. The guide wheel 312 is installed on the cantilever beam 13 arranged on the top front side of the gantry 12. The first steel cable 41 connected to the handle 311 passes around the guide wheel 312 and is connected to the counterweight 21, so as to pull up the counterweight 21 when the handle 311 is pulled down.

[0058] The second training mechanism 32 includes a box body 321, an operating rod 322 and an upper winch 323. The box body 321 is installed on the gantry 12. The operating rod 322 is hinged on the box body 321 and swings on a vertical plane. The upper winch 323 is installed in the box body 321. The second steel cable 42 connected to it is connected to the counterweight 21. The operating rod 322 is transmission-connected to the upper winch 323. When the operating rod 322 is manually driven to swing, the upper winch 323 reels in the second steel cable to pull up the counterweight 21.

[0059] The third training mechanism 33 includes an upper swing arm 331 and a middle winch 332. One end of the upper swing arm 331 is hinged on the gantry 12, and the other end is provided with a handle 333. The handle 333 is vertically arranged. The upper swing arm 331 swings on the horizontal plane. The middle winch 332 is installed on the gantry 12. The third steel cable 43 connected to it is connected to the counterweight 21. The upper swing arm 331 is connected to the middle winch 332 in transmission connection. When the upper swing arm 331 is manually driven to swing by the handle 333, the middle winch 332 reels in the third steel cable 43 to pull up the counterweight 21.

[0060] The fourth training mechanism 34 includes a lower swing arm 341 and a lower winch 342. The lower swing arm 341 is vertically arranged, one end of which is hinged on the gantry 12, and the other end is equipped with two support cylinders 343. The two support cylinders 343 are arranged at intervals to accommodate the legs. The lower winch 342 is installed on the gantry 12, and the fourth steel cable 44 connected to it is connected to the counterweight 21. The lower swing arm 341 is transmission-connected to the lower winch 342. When the lower swing arm 341 is manually driven to swing through the support cylinder 343, the lower winch 342 reels in the fourth steel cable 44 to pull up the counterweight 21.

[0061] The first training mechanism 31, the second training mechanism 32, the third training mechanism 33 and the fourth training mechanism 34 are arranged in sequence from top to bottom, and are each symmetrically arranged in two groups, thereby achieving simultaneous training of left and right arms and left and right legs.

[0062] When in use, a fitness bench is placed in the gantry 12 or a fitness bench is directly set on the gantry 12. The user sits on the fitness bench and pulls down the handle 311 of the first training mechanism 31 to perform high-position pull-down back training; the user stands, grasps and pulls the operating rod 322 to swing it inward or outward in the left and right directions, thereby respectively training the chest and shoulders; the user sits on the fitness bench, grasps and pulls the operating rod 322 to swing it upward or downward in the front and back directions, thereby respectively training the shoulders and back; the user sits on the fitness bench, grasps the handle 333 at the far end to pull the upper swing arm 331 to swing inward in the left and right directions, thereby performing chest training by pinching the chest; the user sits on the fitness bench, puts the legs directly into the corresponding two support cylinders 343, kicks the legs forward to swing the lower swing arm 341 forward, thereby performing leg training.

[0063] When the handle 311, the operating rod 322, the upper swing arm 331 and the lower swing arm 341 are in a natural state (i.e., not manually driven and not subjected to external forces), the counterweight 21 is at its lowest height position; when the handle 311, the operating rod 322, the upper swing arm 331 and the lower swing arm 341 are manually pulled or pulled, the counterweight 21 is pulled up, and its gravity provides resistance for each training mechanism. In order to pull up the counterweight 21, after the steel cable is connected to the counterweight 21, it needs to be extended vertically upward first, and then connected to each training component through the guide wheel. The steel cable 4 is finally connected vertically to the counterweight 21 through the guide wheel, which is a prior art and is not the invention of this application. In addition, when the operating rod 322, the upper swing arm 331 and the lower swing arm 341 are in a natural state, the steel cable 4 is connected to the corresponding winch at only one point, so that when the operating rod 322, the upper swing arm 331 and the lower swing arm 341 swing forward or reverse, the steel cable 4 is wound around the winch in the corresponding forward or reverse direction, thereby realizing two-way operation and providing resistance.

[0064] In the above-mentioned schematic embodiment, each training mechanism of the multi-functional fitness machine is arranged on the gantry 12 on the front side of the frame 1, and is arranged in sequence from top to bottom. The counterweight unit 2 is located on the rear side of the frame 1. The user enters the gantry 12 and can select each training mechanism to perform different strength training, thereby meeting the purpose of comprehensive training. Each training mechanism fully utilizes the vertical space where the gantry 12 is located from top to bottom, thereby not increasing the space occupied by the fitness machine in the front and rear directions, and reducing the external dimensions of the fitness machine. The motion trajectories of other training mechanisms except the first training mechanism 31 are fixed, thereby fixing the user's training movements, making it easier for the user to train, and solving the problem that the current comprehensive trainer cannot meet the requirements of ease of use and small size.

[0065] In some embodiments, the box 321 is hinged on the gantry 12 so that it can be flipped in the left and right directions. The box 321 is fixed in the first training state or the second training state by a limit pin, that is, when the box 321 is in the first training state and the second training state, the limit pins are inserted into the corresponding limit holes of the frame 1, thereby fixing the box 321.

[0066] like Figure 1 As shown, in the first training state, the operating rod 322 is located on the outside in the left-right direction, so that the swing direction of the operating rod 322 is limited to the front-back direction, so that the user's arms can push the operating rod 322 forward to achieve chest training, and the user's arms can pull the operating rod 322 backward to achieve back training.

[0067] like Figure 2 As shown, in the second training state, the operating rod 322 is located on the inner side in the left-right direction, so that the swing direction of the operating rod 322 is limited to the left-right direction, so that the user's arms can push the two operating rods 322 inward to achieve chest clamping training, and the user's arms can push the operating rods 322 outward to achieve shoulder training.

[0068] The box body 321 can be adjusted to two angles, so that the chest, shoulders and back can be trained, and the functionality of the second training mechanism can be improved. In addition, the box body 321 can be turned inward to the second training state, and the second training mechanism can be folded to the inside of the gantry 12, further reducing the volume of the fitness device, so as to facilitate storage.

[0069] In some embodiments, Figure 4 As shown, an operating shaft 324 is installed on the box body 321, and the operating shaft 324 is transmission-connected with the upper winch 323. One end of the operating rod 322 is sleeved on the operating shaft 324. A positioning plate 325 is coaxially arranged on the operating shaft 324. A plurality of positioning holes are arranged on the circumference of the positioning plate 325. The elastic pin 326 installed on the operating rod 322 is inserted into the positioning hole.

[0070] By inserting the elastic pin 326 into different positioning holes, the operating rod 322 is fixed at different angles in the initial state, thereby realizing multiple training modes.

[0071] Specifically, when the box 321 is in the first training state, when the operating rod 322 is in a forward tilted state, the user sitting in the gantry 12 grabs the operating rod 322 with both arms forward, thereby being able to pull the operating rod 322 backward to achieve back training; when the operating rod 322 is switched to a backward tilted state, the user sitting in the same position in the gantry 12 grabs the operating rod 322 with both arms and is able to push it forward to achieve chest training. When the box 321 is in the second training state, when the operating rod 322 is in an outward tilted state, the user standing in front of the gantry 12 can grab the operating rod 322 with both hands and push the operating rod 322 inward to achieve chest clamping training; when the operating rod 322 is switched to an inward tilted state, the user standing in the same position can push the operating rod 322 outward to spread his arms to achieve shoulder training. Figure 5 As shown, the operating shaft can be directly fixedly connected to the upper winch 323.

[0072] In some embodiments, Figure 6 As shown, the operating rod 322 is hinged to the box body through the operating shaft 324, the upper capstan 323 is an inner gear ring, and a central gear 327 is installed on the operating shaft 324. The central gear 327 is located at the center of the upper capstan 323. A planetary carrier is rotatably installed in the box body 321, and a planetary gear 328 is installed on the planetary carrier. The planetary gear 328 is located between the upper capstan 323 and the central gear 327, and meshes with the two.

[0073] The upper capstan 323 of the inner gear ring, the planetary gear 328 and the central gear 327 form a planetary reduction mechanism. In a limited space, a certain transmission ratio is formed between the operating rod 322 and the upper capstan 323 to increase the range of resistance that the counterweight 21 can provide. When the operating rod 322 swings at a small angle, the upper capstan 323 can rotate multiple times, thereby lifting the counterweight 21 to a sufficient height through the steel cable. In addition, the planetary reduction mechanism can swing in the box 321, and when switching between the first training state and the second training state, the effect of the transmission ratio can also be ensured.

[0074] In some embodiments, Figures 7 to 9As shown, the upper swing arm 331 and the lower swing arm 341 are coaxially mounted with a first driving sprocket 334 and a second driving sprocket 344, respectively; the middle reel 332 and the lower reel 342 are coaxially mounted with a first driven sprocket 335 and a second driven sprocket 345, respectively; the first driving sprocket 334 and the first driven sprocket 335 are driven by a chain, and the second driving sprocket 344 and the second driven sprocket 345 are driven by a chain.

[0075] The swing arms and the winches in the third training mechanism 33 and the fourth training mechanism 34 achieve a certain transmission ratio through the size ratio between the active and driven sprockets, thereby increasing the range of resistance provided by the counterweight 21 for the third training mechanism 33 and the fourth training mechanism 34, and the upper swing arm 331 and the lower swing arm 341 do not need to swing too much during training to fully lift the counterweight 21.

[0076] like Figure 7 The right side and Figures 8 to 9 As shown, the third training mechanism and the fourth training mechanism can adopt the same angle adjustment structure as the second training mechanism, change the angle position of the upper swing arm and the lower swing arm, and fix them by elastic pins to achieve multi-angle training adjustment. In addition, the third training mechanism and the fourth training mechanism can be installed as a whole on a shell, the shell is hinged with the gantry, and can be fixed by limit pins. The shell can be turned over to the inside of the gantry by turning the shell inward, upward or downward. At the same time, the upper swing arm and the lower swing arm are also adjusted to a position overlapping with the corresponding shell. The shell folds the third training mechanism and the fourth training mechanism to the inside of the gantry, further reducing the volume of the fitness device, so as to facilitate storage.

[0077] In some embodiments, the counterweight unit 2 further includes a supporting frame 22, the counterweight member 21 includes a plurality of counterweight irons 211, one of the counterweight irons 211 is fixed to the supporting frame 22 via a load-bearing pin 212, the steel cable 4 passes through the mounting hole provided on the supporting frame from top to bottom, and is connected to the limit block 5, and the outer diameter of the limit block 5 is greater than the inner diameter of the mounting hole.

[0078] When the steel cable 4 of a training mechanism is pulled upward, the support frame 22 together with the counterweight iron 211 fixed thereon is lifted up through the limit block 5 of the steel cable 4, providing resistance for the training mechanism. At the same time, the steel cables 4 connected to other training mechanisms remain stationary and extend downward further relative to the bottom of the support frame 22, avoiding the situation where all the steel cables 4 are pushed upward when the steel cables 4 are directly hard-connected with the counterweight 21, causing the steel cables 4 to increase the resistance to lifting the counterweight 21, thereby increasing the training resistance borne by the user, thereby ensuring the accuracy of the training resistance.

[0079] In some embodiments, the counterweight unit 2 further includes a counterweight frame 23, which includes a counterweight seat 231 fixed on the frame and a support plate 232 rotatably mounted on the counterweight seat 231, wherein two support plates 232 are coaxially arranged, and each counterweight iron 211 is located between the two support plates 232. A load-bearing pin 212 is installed on each counterweight iron 211, and the load-bearing pin 212 is horizontally penetrated corresponding to the counterweight iron 211 and the two support plates 232, or vertically penetrated through the supporting frame 22 and threadedly connected to the connecting hole corresponding to the counterweight iron 211, thereby fixing the counterweight iron 211 on the counterweight frame 23, or fixing the counterweight iron 211 to the supporting frame 22 to provide resistance as it rises.

[0080] The two support plates 232 are connected by a rotating shaft, and the support plates 232 are rotatably installed by the rotating shaft. Since the support plates 232 can rotate, the corresponding counterweight iron 211 can be rotated to the upper side, so that it can be connected to the load-bearing frame 22 to provide resistance for the training mechanism. By rotating the support plates 232, different counterweight irons 211 are switched to be connected to the load-bearing frame 22, which improves the convenience of resistance adjustment operation.

[0081] In some embodiments, the counterweights 211 are all fan-shaped and located on the same circumference, so that a plurality of the counterweights are combined into a circular ring structure, and the outer diameter of the circular ring structure is less than or equal to the outer diameter of the support plate.

[0082] The circular ring structure composed of multiple counterweights 211 can be completely located inside the space between the support plates 232, so that the support plates 232 can protect the counterweights 211, prevent the counterweights 211 from being damaged by collision, ensure the weight stability of the counterweights 211, and thus ensure the stability of resistance.

[0083] In some embodiments, a pair of limiting rollers 6 are installed on one side of the upper winch 323, the middle winch 332 and the lower winch 342. After the second steel cable 42, the third steel cable 43 and the fourth steel cable 44 pass through the corresponding two limiting rollers 6, they are respectively connected to the upper winch 323, the middle winch 332 and the lower winch 342. The two limiting rollers 6 clamp the corresponding steel cables 4.

[0084] The two limiting rollers 6 guide and limit the steel cable 4 entering and leaving the winch, so that the steel cable 4 can be smoothly wound onto the winch in the forward or reverse direction, thereby ensuring the stability of the operation of the training mechanism.

[0085] In some embodiments, the training unit 3 further includes a fifth training mechanism 34, the fifth training mechanism 35 includes a slide 351 horizontally arranged in the front-to-back direction, a slide 352 slidably installed on the slide 351, and a foot pedal 353 is arranged on the upper side of the slide 352. The slide 352 is connected to the counterweight 21 through a fifth steel cable 45. When the slide 352 is manually driven to slide forward, the slide 352 pulls up the counterweight 21 through the fifth steel cable 45.

[0086] The fifth training mechanism 34 is added to further expand the function of the fitness device, so that it can provide a more comprehensive training effect. The design of the slide 351 and the slide seat 352 allows the user to perform leg strength training by sliding forward and backward. This training method simulates sports such as rowing and skiing, which can not only strengthen the leg muscles, but also help improve the stability and coordination of the core muscle group.

[0087] 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.
