Opposite ends of the housing 210 may be provided with parallel rotating end faces 214. Opposite side walls of the two rotating cover plates 230 may be convexly provided with rotating shaft protrusions 232, and the rotating shaft protrusions 232 may pass through the housing 210 and be limited on the inner spherical body 100 so that the rotating cover plates 230 are rotatably connected to the housing 210. Moreover, the housing 210 is connected to the inner spherical body 100 to prevent relative rotation between the inner spherical body 100 and the housing 210, ensuring the inertial stability of the maze fitness ball, making the maze fitness ball easier to control, ensuring the exercise rhythm, and improving the exercise efficiency.

[0033] Refer to Figures 1 to 5 In this embodiment, the housing 210 may include two relatively arranged hemispherical covers 211. The two hemispherical covers 211 can respectively cover the inner spherical body 100. The two hemispherical covers 211 are detachably connected to facilitate the assembly, disassembly, and maintenance of the maze fitness ball.

[0034] Rotating card slots 212 and rotating blocks 213 may be respectively provided on opposite side walls of the two hemispherical covers 211.

[0035] Refer to Figure 2 、 Figure 3 and Figure 5 In this embodiment, a limiting rib 2121 may be convexly provided on the circumferential side wall of the rotating card slot 212. The limiting rib 2121 may be spaced from the bottom wall of the rotating card slot 212 for accommodating a part of the rotating block 213. The limiting rib 2121 may extend on the circumferential side wall of the rotating card slot 212 around the axis of the rotating hole 215.

[0036] The rotating block 213 can extend into the rotating slot 212 and can rotate around the axis of the rotating hole 215 within the rotating slot 212, so as to engage the rotating block 213 between the bottom wall of the rotating slot 212 and the limiting rib 2121, thereby enabling the assembly of the two hemispherical covers 211.

[0037] In some other embodiments, the sum of the lengths of the limiting rib 2121 and the rotating block 213 can be less than or equal to the length of the rotating slot 212, so as to facilitate the extension of the rotating block 213 into the rotating slot 212 and enable it to engage with the limiting rib 2121.

[0038] In some other embodiments, limiting ribs 2121 can be provided on both opposite circumferential side walls of the rotating slot 212, and the two limiting ribs 2121 are spaced apart for accommodating a part of the rotating block 213. Both of the limiting ribs 2121 can extend on the opposite circumferential side walls of the rotating slot 212 around the axis of the rotating hole 215.

[0039] In some other embodiments, the limiting rib 2121 can be provided at one end in the extending direction of the rotating slot 212, so as to facilitate the extension and engagement of the rotating block 213 into the rotating slot 212, thereby facilitating the snap - fit connection of the two hemispherical covers 211.

[0041] When the two hemispherical covers 211 are snap - fitted, the connecting portion 2131 and the limiting portion 2132 are extended into the rotating slot 212, and then the two hemispherical covers 211 are relatively rotated around the axis of the rotating hole 215, so that the limiting portion 2132 moves between the bottom wall of the rotating slot 212 and the limiting rib 2121, and the connecting portion 2131 moves between the two limiting ribs 2121, thereby restricting the movement of the two hemispherical covers 211 in the axial direction of the rotating hole 215.

[0042] In some other embodiments, each of the two hemispherical covers 211 is respectively provided with a rotating block 213 and a rotating slot 212. One hemispherical cover 211 can be snap - fitted and connected to the other hemispherical cover 211 respectively through the rotating block 213 and the rotating slot 212 thereon, thereby improving the connection strength of the two hemispherical covers 211.

The axis of the rotating hole 215 is parallel to the arrangement direction of the rotating end face 214.

[0044] In some embodiments, the rotating hole 215 may be located in the middle of the rotating end face 214, so that when the rotating cover plate 230 rotates around the axis of the rotating hole 215, the two hemispherical covers 211 can still enclose a spherical structure with the two rotating cover plates 230.

[0045] In this embodiment, the two hemispherical covers 211 may be provided with rotating ring grooves 216 on the rotating end faces 214.

A part of the rotating cover plate 230 can be accommodated in the rotating ring groove 216, so as to ensure the structural stability and reliability when the rotating cover plate 230 rotates around the axis of the rotating hole 215.

[0046] In some embodiments, there may be multiple rotating ring grooves 216. The multiple rotating ring grooves 216 are arranged coaxially and are sleeved in sequence. The multiple rotating ring grooves 216 can be respectively engaged with a part of the rotating cover plate 230 to ensure the structural stability and reliability when the rotating cover plate 230 rotates.

The fixing cover plate 221 can be accommodated in the circular groove formed by the two fixing grooves 217 enclosing, so as to connect and limit the two hemispherical covers 211, so that the two hemispherical covers 211 are locked after being engaged, and the structural strength of the outer spherical shell 200 is improved.

[0049] When the two hemispherical covers 211 are engaged, the two fixing grooves 217 form a circular groove in combination, and the fixing cover plate 221 is accommodated in the circular groove, so that the housing 210 formed by the combination of the two hemispherical covers 211 can rotate synchronously around the axis of the rotating hole 215.

[0050] In some embodiments, a first bolt 222 may protrude from the side of the fixing cover plate 221 facing the housing 210. The first bolt 222 can be threadedly connected to the two hemispherical covers 211, so that the fixing cover plate 221 can be detachably connected to the housing 210, and the two hemispherical covers 211 can be limited to rotate around the axis of the rotating hole 215.

[0051] In some other embodiments, the first bolt 222 can pass through the housing 210 and be connected to the inner sphere 100, thereby improving the connection strength between the fixed cover plate 221 and the housing 210, and can limit the relative rotation between the inner sphere 100 and the outer spherical shell 200, ensuring the inertial stability of the maze fitness ball during operation and facilitating the play of the maze fitness ball.

[0052] The inner sphere 100 can be provided with a limiting screw hole 101 relative to the first bolt 222. The limiting screw hole 101 is used for connecting and limiting with the first bolt 222, thereby facilitating the limitation between the housing 210 and the inner sphere 100.

[0055] In some embodiments, the circumferential side wall of the fixed cover plate 221 can be threadedly connected to the inner circumferential wall of the fixing groove 217. The first bolt 222 can be separately arranged from the fixed cover plate 221 so that the first bolt 222 can connect the housing 210 and the inner sphere 100, so that the housing 210 and the inner sphere 100 can rotate synchronously around the axis of the rotating hole 215.

[0056] Refer to Figures 1 to 5 , in this embodiment, the rotating cover plate 230 is rotatably connected to the rotating end face 214 of the hemispherical cover 211. The rotation axis of the rotating cover plate 230 is coaxially arranged with the axis of the rotating hole 215, so that the rotating cover plate 230 can rotate relative to the hemispherical cover 211 around the axis of the rotating hole 215, thereby realizing the operation of the maze fitness ball between both hands.

In some other embodiments, the axes of the second bolt 242 and the third bolt 244 may be arranged parallel to the rotation axis of the rotating boss 232.

[0077] Refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , in this embodiment, the inner sphere 100 can be accommodated in the housing 210 to improve the quality of the maze fitness ball, thereby improving the fitness and exercise effects of users. The inner sphere 100 is connected to the housing 210 so as to be able to rotate synchronously with the housing 210.

[0078] The inner sphere 100 may be recessed with a limiting groove 102 relative to the rotating bearing 240. The limiting groove 102 is used to accommodate the rotating bearing 240. The inner peripheral wall of the limiting groove 102 fits against the outer peripheral wall of the outer ring 243, so that the inner sphere 100 can rotate around the axis of the rotating bearing 240 and can also limit the radial movement of the inner sphere 100 along the rotating boss 232, ensuring the reliability and stability of the rotation of the inner sphere 100 around the rotating boss 232.

[0079] In some embodiments, the limiting groove 102 on the inner sphere 100 can accommodate the rotating bearing 240 and the end of the rotating boss 232 facing the center of the housing 210, so as to improve the structural strength of the maze fitness ball and extend the service life of the maze fitness ball.

[0080] Refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , in this embodiment, a travel channel 120 may be provided inside the inner sphere 100. The two ends of the travel channel 120 are respectively arranged on the bottom walls of the two limiting grooves 102, and the two ends of the travel channel 120 are respectively communicated with the two accommodation cavities 2323.

[0081] In some embodiments, a boss portion 103 may protrude from the bottom wall of the limit groove 102 relative to the inner ring 241. The outer peripheral wall of the boss portion 103 may be attached to the inner peripheral wall of the inner ring 241, and a port of the access stroke channel 120 is formed on a side wall of the boss portion 103 away from the center of the inner sphere 100.

[0082] Refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 In this embodiment, the maze fitness ball may further include rolling beads 300. The rolling beads 300 are rollably received in the stroke channel 120 and the two receiving cavities 2323, so that the rolling beads 300 can roll from one receiving cavity 2323 to the other receiving cavity 2323 through the stroke channel 120. When the rolling beads 300 move into the receiving cavity 2323, the user can confirm the state of the rolling beads 300 through the observation channel 2321.

[0083] In this embodiment, the stroke channel 120 is meanderingly arranged inside the inner sphere 100, so that the stroke channel 120 is in a maze shape. The user can not only rotate the inner sphere 100 to solve the maze to exercise the user's brainpower, but also exercise the physique by operating the maze fitness ball.

[0084] The rolling beads 300 roll in the stroke channel 120 under the action of gravity and inertia. When the user solves the maze through the maze fitness ball, the rolling beads 300 can roll downward to impact the lower inner wall of the stroke channel. The vibration generated by the impact of the rolling beads 300 can be transmitted to the user's palm, thereby reminding the user to rotate the inner sphere 120 to change the rolling direction of the rolling beads 300, so that the user can solve the maze and exercise at the same time to exercise the user's physique and brainpower.

[0085] In some embodiments, the extension path of the stroke channel 120 is meanderingly designed according to fitness movements, so that the rolling beads 300 roll rhythmically in the stroke channel 120. When the user rotates the housing 210 and the inner sphere 100, the rolling beads 300 move in the stroke channel 120 under the action of gravity and inertia. When the user performs fitness movements, the rolling beads 300 can impact the lower inner wall of the stroke channel 120. The vibration generated by the impact of the rolling beads 300 can be transmitted to the user's palm to inform the user that the rolling beads 300 are moving forward in the stroke channel 120, thereby reminding the user to change the fitness movements, adjust the fitness rhythm, and assist the user in fitness.

[0086] In other embodiments, the stroke channel 120 may be assembled by a plurality of right-angle extension segments and / or a plurality of arc extension segments, so that the extension trajectory of the stroke channel 120 is complex and changeable, so as to be applicable to various fitness movement requirements and various maze difficulty requirements.

[0087] Refer toFigure 6 and Figure 7 In this embodiment, the inner sphere 100 may include a plurality of splicing plates 130. Engaging structures 133 may be provided on the facing side walls of any two adjacent splicing plates 130, so that the plurality of splicing plates 130 can be spliced to form the inner sphere 100, thereby facilitating the disassembly and assembly of the inner sphere 100.

[0088] When the rolling beads 300 cannot move through the travel channel 120 into the accommodation cavity 2323, the user can move the rolling beads 300 into any accommodation cavity 2323 by disassembling the two hemispherical covers 211 and the plurality of splicing plates 130, so that the user can solve the maze again.

[0089] In some embodiments, the engaging structure 133 may include a splicing slot 1331 and a splicing block 1332. The splicing slot 1331 and the splicing block 1332 are respectively provided on the facing side walls of any two adjacent splicing plates 130, and the splicing slot 1331 and the splicing block 1332 are located outside the travel channel 120, so as to facilitate the splicing of the plurality of splicing plates 130 to form the inner sphere 100.

[0090] In other embodiments, the plurality of splicing plates 130 are bonded to each other so that the plurality of splicing plates 130 can be combined to form the inner sphere 100.

[0091] Refer to Figure 7 In this embodiment, relatively arranged extension grooves 131 may be recessed on the facing side walls of any two adjacent splicing plates 130. After any two adjacent splicing plates 130 are connected, the two extension grooves 131 on the facing side walls of any two adjacent splicing plates 130 can be combined to form an extension channel. A travel through hole 132 is formed in the splicing plate 130, and the travel through hole 132 can communicate with the extension grooves 131 on both sides of the splicing plate 130. After the plurality of splicing plates 130 are spliced, the plurality of extension channels and the plurality of travel through holes 132 can be combined to form a travel channel 120.

[0092] In some embodiments, the extension groove 131 may extend irregularly on the side wall of the splicing plate 130, so that after the plurality of splicing plates 130 are spliced to form the inner sphere 100, the plurality of extension channels and the travel through holes 132 are combined to form a travel channel 120 with various structures, so as to facilitate the exercise of the user's brain power.

[0093] In some embodiments, at least one travel through hole 132 is provided on one splicing plate 130 to facilitate the rolling of the rolling beads 300 in the travel channel 120.

[0094] In some embodiments, multiple splicing plates 130 may be arranged in sequence along the axial direction of the rotation hole 215. A stroke through hole 132 is provided on the two outermost splicing plates 130 to communicate with the accommodation cavity 2323 inside the rotation shaft protrusion 232, so as to facilitate the rolling beads 300 to enter the accommodation cavity 2323. In other embodiments, the axis of the stroke through hole 132 on the two outermost splicing plates 130 is coaxially arranged with the rotation axis of the rotation shaft protrusion 232, so that the stroke through hole 132 corresponds to the observation hole 2325.

[0095] Referring to Figures 1 to 7 , in the present utility model, during the production and assembly of the maze fitness ball, an extension groove 131 and a stroke through hole 132 are provided on the splicing plate 130. Then, multiple splicing plates 130 are connected to form the inner sphere 100, so that multiple extension channels and stroke through holes 132 inside the inner sphere 100 form a stroke channel 120.

[0096] Insert the rotation shaft protrusion 232 into the rotation hole 215, so that the arc-shaped cover body 231 covers the rotation end face 214. Then, the rotation bearings 240 are respectively bolted to the rotation shaft protrusion 232 and the hemispherical cover 211 to rotatably limit the rotation cover plate 230 on the hemispherical cover 211.

[0097] Lift the two hemispherical covers 211 onto the inner sphere 100, so that the rotation bearings 240 are accommodated in the limit groove 102, and the limit boss extends into the inner ring 241. After inserting the rotation catch 213 into the rotation slot 212, the two hemispherical covers 211 rotate around the rotation axis of the rotation shaft protrusion 232, so as to realize the snap limit between the two hemispherical covers 211.

[0098] Finally, place the fixed cover plate 221 in the two fixed grooves 217, so that the first bolt 222 passes through the housing 210 and is bolted to the inner sphere 100, thereby connecting the housing 210 and the inner sphere 100, and enabling the housing 210 and the inner sphere 100 to rotate synchronously, so as to facilitate the user to rotate the housing 210 to adjust the rolling direction of the rolling beads 300.

[0099] When the user operates the maze fitness ball, the finger extends into the finger sleeve 2312, so that the palm fits on the rotation cover plate 230, and the finger can fit on the housing 210. The rotation cover plate 230 rotates relative to the housing 210 around the rotation axis of the rotation shaft protrusion 232, so as to enable the maze fitness ball to rotate at a large angle between the two hands, thereby enabling the maze fitness ball to be applicable to a variety of playing methods and improving the application range of the maze fitness ball. Moreover, when the user operates the maze fitness ball, the relative rotation of the rotation cover plate 230 and the housing 210 can also unlock the maze to exercise the brainpower.
