[0034] To further understand the content of the present invention, the present invention will be described in detail with reference to the drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention rather than limiting it.

[0035] The following will be further described in detail with reference to the attached Figures 1-8 This embodiment will be further described in detail.

[0036] Please refer to Figures 1-3 , a portable fitness exercise bike in this embodiment includes a main body 100. A rotatable rotating shaft 110 is provided inside the main body 100. Both ends of the rotating shaft 110 extend outside the main body 100. Pedal boards 111 are respectively provided at the extending ends of the rotating shaft 110. Front clamping grooves 300 and rear clamping grooves 310 are oppositely provided on the bottom surface of the main body 100. Removable legs 120 are provided in the front clamping grooves 300 and the rear clamping grooves 310. Connecting holes 200 are oppositely provided on one side surface of the legs 120. A connecting assembly that can extend into the corresponding connecting holes 200 is further provided inside the main body 100. A lifting cavity 320 communicating with the rear clamping groove 310 is provided inside the main body 100. A telescopic rolling assembly is provided in the lifting cavity 320. The rolling assembly is used to assist in moving the main body 100.

[0037] In this embodiment, the rotating shaft 110 is rotatably installed on the main body 100 through a bearing. Thus, the rotational installation of the rotating shaft 110 is preferably achieved. Among them, a damping device connected to the rotating shaft 110 is provided inside the main body 100. It is a conventional structure. When the user needs to exercise, first, sit on the seat, and then place both feet on the pedal boards 111 respectively. Thus, stepping on the pedal boards 111 drives the rotating shaft 110 to rotate, thereby simulating riding a bike and exercising the body. This is the prior art, and its principle will not be elaborated here;

[0038] Among them, through the setting of the legs 120, when exercising, the contact area between the main body 100 and the ground can be increased to prevent the main body 100 from tilting during exercise and affecting its use;

[0039] Among them, through the detachable setting of the outriggers 120, when the main body 100 needs to be carried, the outriggers 120 can be removed to prevent them from protruding outside the main body 100. Compared with the existing ones, during carrying, the volume and weight of the exercise bike can be reduced, facilitating the carrying of the main body 100.

[0040] Among them, through the setting of the connecting component, the outriggers 120 can be detachably installed in the front clamping groove 300 and the rear clamping groove 310, facilitating the disassembly and assembly of the outriggers 120 on the main body 100.

[0041] Among them, through the setting of the rolling component, when the main body 100 needs to be moved, first, the outriggers 120 are removed, and then the rolling component is extended out of the lifting cavity 320. At this time, one end of the main body 100 is lifted to make the rolling component contact the ground, and then the main body 100 is moved, changing the friction between the main body 100 and the ground from sliding friction to rolling friction, reducing the friction force, thereby making the movement of the main body 100 more convenient. When the movement of the main body 100 is completed, the rolling component can be retracted into the lifting cavity 320 to prevent it from affecting the installation of the outriggers 120.

[0042] During the actual use of this embodiment, anti-slip patterns are provided on the bottom end surface of the outriggers 120. Through the setting of the anti-slip patterns, the friction force between the outriggers 120 and the ground is increased, preventing the main body 100 from shifting during exercise and affecting the use of this exercise bike.

[0043] Among them, in order to facilitate fixing the user's sole, an elastic sleeve 112 is provided on the pedal 111. The user's sole can be clamped between the elastic sleeve 112 and the pedal 111, preventing the sole from detaching from the pedal 111 during exercise and affecting the use of this exercise bike.

[0044] As Figures 1-5 shown, in this embodiment, drive cavities 500 are relatively provided on both sides inside the main body 100, and connection grooves 512 communicating with the front clamping groove 300 or the rear clamping groove 310 are provided in the drive cavities 500; the connecting component includes a movable plate 530 provided in the drive cavity 500, and a connecting pin 540 that can extend into the connecting hole 200 through the connection groove 512 is provided on one end surface of the movable plate 530. The connecting pin 540 extends into the connecting hole 200 for connecting the outriggers 120 and the main body 100.

[0045] In this embodiment, when the outrigger 120 needs to be installed, the outrigger 120 can be snapped into the front clamping groove 300 or the rear clamping groove 310. The connecting pin 540 in the moving drive cavity 500 is moved so that the connecting pin 540 extends into the corresponding connecting hole 200 through the connecting groove 512 in the drive cavity 500. Thus, the fixing of the outrigger 120 in the front clamping groove 300 or the rear clamping groove 310 is completed, that is, the connection between the outrigger 120 and the main body 100 is realized. When the connection between the outrigger 120 and the main body 100 needs to be released, the connecting pin 540 extending into the connecting hole 200 can be moved into the drive cavity 500, thereby releasing the connection between the outrigger 120 and the main body 100.

[0046] As Figures 1-5 shown, in this embodiment, a guide rod 533 is provided on the other end face of the moving plate 530. A guide groove 520 for the guide rod 533 to extend into is provided in the main body 100. A spring 532 for driving the moving plate 530 to move is sleeved on the guide rod 533. A plug plate 550 is provided at the opening of the drive cavity 500. A sliding groove 551 is provided on the plug plate 550. A grip rod 531 that moves in the sliding groove 551 is provided on the moving plate 530 on the same side.

[0047] In this embodiment, the side wall of the moving plate 530 is in sliding fit with the inner wall of the drive cavity 500. With this structure, the connecting pin 540 can always be kept in a state of being aligned with the connecting groove 512. One end of the spring 532 abuts against the connecting pin 540, and the other end of the spring 532 abuts tightly against the side wall of the drive cavity 500. Under the elastic force of the spring 532, the moving plate 530 can move in the direction close to the connecting groove 512, so that the connecting pin 540 can always be kept in a state of extending out of the connecting groove 512.

[0048] In actual use of this embodiment, through the setting of the guide rod 533, the spring 532 can be installed and will not break away from the guide rod 533. Through the setting of the guide groove 520, the guide rod 533 can move along with the moving plate 530.

[0049] Among them, through the setting of the grip rod 531 and the sliding groove 551, when the connection between the outrigger 120 and the main body 100 needs to be released, the grip rod 531 can be moved along the sliding groove 551 in the direction away from the connecting groove 512, driving the moving plate 530 to move. Finally, the connecting pin 540 is retracted from the connecting hole 200 and into the drive cavity 500.

[0050] As Figure 5 shown, in this embodiment, a communication groove 510 is provided between the relatively arranged drive cavities 500. A connecting rod 511 that moves in the communication groove 510 is provided between the relatively arranged moving plates 530 on both sides of the main body 100.

[0051] In this embodiment, through the arrangement of the connecting rod 511 of the connecting groove 510, the moving plates 530 located on both sides of the main body 100 and opposite to each other can move synchronously. When it is necessary to remove the leg 120 in the front clamping groove 300 or the rear clamping groove 310, only by moving the grip rod 531 on one side of the main body 100, the connecting pin 540 can be synchronously extended out of the connecting hole 200, which is convenient for operation.

[0052] As Figures 1-3 shown, in this embodiment, limiting grooves 301 communicating with the front clamping groove 300 or the rear clamping groove 310 are oppositely arranged at the bottom end surface of the main body 100, and clamping portions 210 that can extend into the limiting grooves 301 are arranged on the legs 120.

[0053] In this embodiment, the limiting grooves 301 are located at the central position of the bottom end surface of the main body 100. Through the arrangement of the clamping portions 210 and the limiting grooves 301, when installing the legs 120 and the main body 100, the clamping portions 210 can be aligned with the limiting grooves 301. At this time, the connecting pins 540 can also be aligned with the connecting grooves 510 without additional alignment, making the installation of the legs 120 relatively convenient.

[0054] As Figures 1-5 shown, in this embodiment, a first inclined surface 541 is arranged on the connecting pin 540, and a second inclined surface 201 corresponding to the first inclined surface 541 is arranged on the leg 120.

[0055] In this embodiment, the connecting pin 540 has a first inclined surface 541, and the leg 120 has a second inclined surface 201. When installing the leg 120 and the main body 100, that is, when the leg 120 is clamped into the front clamping groove 300 or the rear clamping groove 310, during the clamping process of the leg 120, the second inclined surface 201 presses the first inclined surface 541, thereby automatically moving the connecting pin 540 towards the driving cavity 500. In this process, there is no need to manually move the grip rod 531. When the leg 120 is completely clamped into the front clamping groove 300 or the rear clamping groove 310, the connecting pin 540 extends into the connecting hole 200 from the driving cavity 500 under the thrust of the spring 532 to complete the connection between the main body 100 and the leg 120.

[0056] As Figures 3-8 shown, in this embodiment, the rolling assembly includes a lifting plate 710 that is arranged in the lifting cavity 320 and can move. Connecting plates 720 are oppositely arranged on the lifting plate 710. A rolling wheel 722 that can roll is arranged between the connecting plates 720. A vertical groove 700 communicating with the lifting cavity 320 is arranged on the side wall of the main body 100. A threaded rod 711 that moves in the vertical groove 700 is arranged on the lifting plate 710. One end of the threaded rod 711 extends out of the vertical groove 700, and a nut 712 is threadedly connected to the extended end of the threaded rod 711.

[0057] In this embodiment, when the main body 100 needs to be moved, first, the legs 120 located in the front clamping groove 300 and the rear clamping groove 310 are removed. Then, the nuts 712 located on both sides of the main body 100 are loosened in sequence, and the threaded rod 711 is moved downward to drive the lifting plate 710 to move, so that the connecting plate 720 and the rolling wheel 722 extend out of the lifting cavity 320. The nuts 712 on both sides of the main body 100 are tightened in sequence. At this time, the positions of the connecting plate 720 and the rolling wheel 722 are fixed. At this time, one side of the main body 100 can be lifted to make the rolling wheel 722 contact the ground, and the main body 100 is moved. At this time, the friction between the main body 100 and the ground changes from sliding friction to rolling friction, reducing the frictional force and making it more convenient to move the main body 100;

[0058] Among them, the rolling wheel 722 is installed in the connecting plate 720 through the connecting shaft 721. A bearing for rotatably installing the connecting shaft 721 is provided in the connecting plate 720. Thus, the rotatability of the rolling wheel 722 is realized.

[0059] As Figures 1-4 shown, in this embodiment, a holding portion 400 is formed by inward depression at the side wall of the main body 100, and a holding groove 410 is provided in the holding portion 400.

[0060] In this embodiment, when the main body 100 needs to be moved, the user passes the palm through the holding groove 410, thereby realizing the holding and lifting of the main body 100 so that the rolling wheel 722 contacts the ground, facilitating the rotation or movement of the main body 100;

[0061] Among them, through the setting of the holding portion 400, the width of the main body 100 is shortened, making it more convenient for the operator to hold.

[0062] Working principle: When the main body 100 needs to be moved, first, move the moving grip rod 531 so that the connecting pin 540 extends out of the connecting hole 200 and retracts into the driving cavity 500. Remove the legs 120 in the front clamping groove 300 and the rear clamping groove 310. Then, loosen the nuts 712 located on both sides of the main body 100 in sequence, and move the threaded rod 711 downward to drive the lifting plate 710 to move, so that the connecting plate 720 and the rolling wheel 722 extend out of the lifting cavity 320. Tighten the nuts 712 on both sides of the main body 100 in sequence. At this time, the positions of the connecting plate 720 and the rolling wheel 722 are fixed. One side of the main body 100 can be lifted to make the rolling wheel 722 contact the ground, and the main body 100 is moved. The friction between the main body 100 and the ground changes from sliding friction to rolling friction, reducing the frictional force and making it more convenient to move the main body 100; When it is moved to the required position, the connecting plate 720 and the rolling wheel 722 are retracted into the lifting cavity 320, and the legs 120 are installed in the front clamping groove 300 and the rear clamping groove 310. At this time, the user can move a seat to a suitable position at the bicycle and sit on the seat. Then, stretch the sole of the foot onto the pedal 111 to make the rotating shaft 110 rotate for exercise.
