[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model comprises a box, a first folding frame, a first seat, an upper limb exercise mechanism, a fixed shaft, a winding cylinder, and a second steel wire rope. When a person needs to exercise their upper limbs, the first seat is flipped off the box, the first folding frame is pulled out of the box, and unfolded to support the ground. Then, the first rope is threaded onto the corresponding pulley group in sequence. The person sits on the first seat and holds the two pull rings with both hands, which can be pulled to move the two pull rings, causing the two first ropes to drive the second steel wire rope to move, thus enabling upper limb exercise.

[0015] 2. This utility model, through a rowing machine mechanism, a first steel wire rope, a second folding frame, and a second seat, first flips the second seat off the housing and pulls the second folding frame out of the housing. Then, the second folding frame is adjusted to unfold and extend to support the ground. The person sits on the second seat, with both feet on the two footrests and hands on the two handles, and can then start rowing. When the person moves by stepping on the footrests, it moves the moving rod, compressing the second spring. At the same time, the person pulls the handles to move, causing the rowing rod to swing around the second folding frame, which pulls the second rope and the first steel wire rope, thereby causing the winding drum to provide resistance to the first steel wire rope.

[0016] 3. This utility model utilizes a lower limb exercise mechanism. First, the mounting frame is fitted onto the rotating shaft.

[0030] 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.

[0031] like Figure 1-10As shown, this embodiment proposes a portable combined fitness equipment, including a housing 1. A walking mechanism is provided at the bottom of the housing 1, allowing personnel to easily carry and move the housing 1, thus enabling its use in different environments and improving the flexibility of the device. Furthermore, the housing 1 can integrate and store the exercise equipment inside, without occupying more space. A first folding frame 17 and a second folding frame 12 are slidably arranged on the inner wall of the housing 1. Slide rails corresponding to the first folding frame 17 and the second folding frame 12 are provided inside the housing 1 to ensure smooth sliding of the first folding frame 17 and the second folding frame 12 within the housing 1. The middle part of the second folding frame 12 is movably connected to the first seat 6. An upper limb exercise mechanism is installed on the first folding frame 17. The first seat 6 is used for seating. The first folding frame 17 is foldable and retractable within the housing 1. After being pulled out of the housing 1, the first folding frame 17 unfolds and supports itself on the ground, allowing a person to sit on the first seat 6 and use the upper limb exercise mechanism to exercise their arms. When the first folding frame 17 is not in use, it can be stored back into the housing 1 to prevent it from taking up too much space. The middle part of the second folding frame 12 is movably connected to the second seat 7. When the second seat 7 and the first seat 6 are in the retracted state, they are secured by a latch. The second seat 7 or the first seat 6 is positioned at the middle of the housing 1 to prevent accidental displacement of the housing 1 during movement. The second folding frame 12 is equipped with a rowing machine mechanism and a lower limb exercise mechanism. The lower limb exercise mechanism is detachably connected to the rowing machine mechanism, allowing the user to sit on the second seat 7 and exercise using the rowing machine. The lower limb exercise mechanism can be installed on the rowing machine mechanism to facilitate different exercise methods. A fixed shaft 10 is fixedly connected to the inner wall of the housing 1. Two opposing winding cylinders 21 are elastically sleeved on the fixed shaft 10, allowing the winding cylinders 21 to rotate on the fixed shaft 10 with rotational resistance, thus ensuring normal subsequent exercise. Additionally, the winding… The cylinder 21 has an automatic reset feature. A first steel wire rope 13 and a second steel wire rope 22 are wound on the two winding cylinders 21 respectively. The first steel wire rope 13 is connected to the rowing machine mechanism, and the second steel wire rope 22 is connected to the upper limb exercise mechanism. With the above structure, the equipment for upper limb exercise, rowing machine exercise, and lower limb exercise can be integrated into the housing 1. Therefore, it can provide people with different exercises, and the operation is more convenient. It also effectively reduces the overall volume and makes assembly more convenient and flexible, thereby improving the practicality of the combined fitness equipment. The mechanics, parts, and equipment in this device all adopt conventional models in the existing technology, which will not be described in detail here.

[0032] like Figure 3 and Figure 5As shown, the upper limb exercise mechanism includes two sets of pulleys 18, which are respectively installed on both sides of the first folding frame 17. Each set of pulleys 18 is equipped with a first rope 19, one end of which is fixedly connected to a pull ring 20, and the other end of which is connected to one end of a second steel wire rope 22. This structure facilitates upper limb exercise for the user. In specific operation, the first seat 6 is flipped off the housing 1, and then the first folding frame 17 is pulled out of the housing 1. The first folding frame 17 is unfolded to support the ground. Then, the first ropes 19 are threaded onto the corresponding pulley groups 18 in sequence. The person sits on the first seat 6 and holds the two pull rings 20 with both hands. Pulling the two pull rings 20 moves the two first ropes 19, which in turn move the second steel wire rope 22. This further causes the winding drum 21 to rotate on the fixed shaft 10. Since the winding drum 21 has an elastic restoring effect on the fixed shaft 10, the person will experience resistance when pulling the pull rings 20, thus achieving the exercise of the person's upper limbs.

[0033] like Figure 4 , Figure 7 and Figure 10 As shown, the rowing machine mechanism includes a fixed rod 26 and two rowing poles 28. The fixed rod 26 is fixedly connected to the second folding frame 12. The bottom ends of the two rowing poles 28 are movably connected to the second folding frame 12 by bolts. The top ends of the two rowing poles 28 are fixedly connected to handles 30. The middle of the two rowing poles 28 is fixedly connected to a second rope 35. One end of each second rope 35 is connected to one end of a first wire rope 13. A guide rod 29 is passed through the middle of the fixed rod 26. One end of the guide rod 29 is fixedly connected to a moving rod 31. Both ends of the moving rod 31 are fixedly connected to footrests 32. A second spring 27 is sleeved on the surface of the guide rod 29 and is fixedly connected between the moving rod 31 and the fixed rod 26. With the above structural arrangement, the rowing machine can achieve the following: To exercise on the rowing machine, the second seat 7 is flipped off the housing 1, and the second folding frame 12 is pulled out of the housing 1. The second folding frame 12 is then extended to support the ground. The person sits on the second seat 7, places their feet on the two footrests 32, and holds the two handles 30. The exercise can then begin. When the person moves the footrests 32, the moving rod 31 moves, compressing the second spring 27. At the same time, the person pulls the handles 30, causing the rowing bar 28 to swing around the second folding frame 12, which pulls the second rope 35 and the first steel wire rope 13, thus providing resistance to the first steel wire rope 13 through the winding drum 21.

[0034] like Figure 2 and Figures 7 to 9As shown, the lower limb exercise mechanism includes a rotating shaft 9 and a mounting frame 33. The rotating shaft 9 is rotatably connected to the inner wall of the housing 1, and both ends of the rotating shaft 9 pass through the housing 1 and are equipped with counterweights 8. The mounting frame 33 is fitted onto the surface of the rotating shaft 9. A main sprocket 25 is fixedly connected to the middle of the rotating shaft 9, and a chain 34 is fitted onto the surface of the main sprocket 25. A bicycle assembly 15 is provided at the end of the mounting frame 33 away from the rotating shaft 9, and the chain 34 is fitted onto the secondary sprocket of the bicycle assembly 15. Connecting rods 16 are hinged to both sides of the mounting frame 33, and the bottom ends of the two connecting rods 16 are engaged with the moving rod 31. U-shaped handlebars 14 are detachably connected to the two grips 30. With the above structure, a person can perform bicycle exercise. In specific operation, the mounting frame 33 is fitted onto the rotating shaft 9, and then the two connecting rods 16 are engaged with the moving rod 31. 1. This ensures the stability of the mounting frame 33. Next, the chain 34 is connected to the main sprocket 25 on the pivot 9. Then, the U-shaped handle 14 is installed on the two grips 30 to prevent the U-shaped handle 14 from swinging freely. The bottom end of the rowing bar 28 is tightened between the second folding frame 12 to prevent the rowing bar 28 from swinging freely. Then, the person sits on the seat on the bicycle assembly 15 and holds the U-shaped handle 14 to start exercising using the bicycle assembly 15. During use, the person will rotate the counterweight 8 and the pivot 9 together, which will provide resistance to the person's lower limbs. In addition, the person can remove and install the counterweight 8 to adjust the resistance, so that the person can exercise according to their own tolerance. The removal and installation of the counterweight 8 is a mature existing technology and will not be described in detail here.

[0035] like Figure 6 As shown, a first spring 24 is fixed to the inner wall of the winding cylinder 21, and the first spring 24 is sleeved on the surface of the fixed shaft 10. The other end of the first spring 24 is fixed to the inner bottom wall of the box 1. With the setting of the first spring 24, the winding cylinder 21 has the effect of elastic reset. When the first steel wire rope 13 or the second steel wire rope 22 on the winding cylinder 21 is pulled, the first spring 24 will provide resistance to the winding cylinder 21, so that the person can exercise normally.

[0036] like Figure 6 As shown, drum brakes 23 are installed at both ends of the two fixed shafts 10, and the brake drum of the drum brake 23 is connected to the winding cylinder 21. The drum brake 23 is a mature existing technology and will not be described in detail here. Adjustment components for adjusting the resistance of the drum brake 23 are provided on both sides of the housing 1. With the above structure, it is convenient for personnel to adjust the rotational resistance of the winding cylinder 21, so as to enable personnel to adapt to different exercise intensities.

[0037] like Figures 1 to 3 and Figure 6As shown, the adjustment assembly includes an adjustment handle 3, which is rotatably connected to the side of the housing 1. One end of the adjustment handle 3 is connected to the cam of the drum brake 23. The side of the housing 1 has slots 5 arranged in a circumferential array. A rod 4 is inserted through the adjustment handle 3, and one end of the rod 4 is inserted into one of the slots 5. With the above structure, it is easy to adjust the contact friction between the drum brake 23 and the winding cylinder 21, thereby adjusting the resistance during upper limb exercise. In specific operation, the rod 4 is pulled out from the slot 5, and then the slot 5 is rotated to drive the cam of the drum brake 23 to rotate, further adjusting the contact friction between the two brake shoes and the brake drum in the drum brake 23. After adjustment, the rod 4 can be inserted into the corresponding slot 5 to ensure that the slot 5 does not rotate arbitrarily.

[0038] like Figures 1 to 3 and Figure 10 As shown, the walking mechanism includes a pull rod 11, which is slidably disposed inside the box 1. The left end of the pull rod 11 extends to the outside of the box 1. Two moving wheels 2 are installed at the bottom of the right end of the box 1. Support legs are fixedly connected to the bottom surface of the box 1. The sliding of the pull rod 11 inside the box 1 is a mature existing technology. With the above structure, it is easy for personnel to pull out the pull rod 11 to pull the box 1 for walking, so as to facilitate carrying it for use in different scenarios. When the box 1 stops moving, the support legs at the bottom of the box 1 also ensure the stability of the box 1.

[0039] The working principle and usage of this utility model are as follows: When a person needs to carry and move the box 1, they simply pull out the lever 11, hold the lever 11, and move it on the ground using the moving wheels 2 to move the box 1. This allows for exercise even when out and about. When a person needs to exercise their upper limbs, the first seat 6 is flipped off the box 1, and then the first folding frame 17 is pulled out from the box 1 and unfolded to support the ground. Next, the first ropes 19 are threaded onto the corresponding pulley sets 18. The person sits on the first seat 6 and holds the two pull rings 20 with both hands, which can then be pulled to move the two first ropes. The cable 19 moves the second steel wire rope 22, allowing for upper limb exercise. When a person needs to exercise on the rowing machine, the second seat 7 is flipped off the housing 1, and the second folding frame 12 is pulled out of the housing 1. The second folding frame 12 is then extended to support the ground. The person sits on the second seat 7, places their feet on the two footrests 32, and holds the two handles 30. The rowing machine exercise can then begin. When the person moves the footrests 32, the moving rod 31 moves, compressing the second spring 27. Simultaneously, the person pulls the handles 30, causing the rowing rod 28 to swing around the second folding frame 12. When the device is moved, the second rope 35 and the first wire rope 13 are pulled, which in turn causes the winding drum 21 to provide resistance to the first wire rope 13. When the user needs to use the lower limb exercise mechanism, the mounting frame 33 is fitted onto the rotating shaft 9, and then the two connecting rods 16 are snapped onto the moving rod 31 to ensure the support stability of the mounting frame 33. Next, the chain 34 is fitted onto the main sprocket 25 on the rotating shaft 9, and then the U-shaped handle 14 is installed on the two grips 30 to prevent the U-shaped handle 14 from swinging freely. The bottom end of the rowing pole 28 is tightened between the rowing pole 28 and the second folding frame 12 to prevent the rowing pole 28 from swinging freely. Then, the user sits on the seat on the bicycle assembly 15 and holds the U-shaped handle 14. Exercise can begin using bicycle component 15. During use, the user will rotate the counterweight 8 and the pivot 9, thus providing resistance to the user's lower limbs. The user can also detach and adjust the resistance of the counterweight 8 to adjust the intensity according to their own comfort level, making it more flexible to use. When the user needs to adjust the pulling resistance of the first steel cable 13 or the second steel cable 22, simply pull the insert rod 4 out of the slot 5, and then rotate the slot 5 to rotate the cam of the drum brake 23, further adjusting the contact friction between the two brake shoes and the brake drum in the drum brake 23. After adjustment, the insert rod 4 can be inserted into the corresponding slot 5.
