[0029] To more clearly illustrate the technical solutions of the embodiments of this specification, the following will briefly introduce the accompanying drawings required for the description of the embodiments. Obviously, the accompanying drawings in the following description are only some examples or embodiments of this specification. For those of ordinary skill in the art, without creative efforts, this specification can also be applied to other similar scenarios based on these drawings. Unless obvious from the language context or otherwise stated, the same reference numerals in the figures represent the same structure or operation.

[0030] It should be understood that the "system", "device", "unit" and / or "module" used herein is a method for distinguishing different components, elements, parts, portions or assemblies at different levels. However, if other words can achieve the same purpose, the said words can be replaced by other expressions.

[0031] As shown in this specification, unless the context clearly indicates an exceptional situation, words such as "a", "an", "one" and / or "the" are not specifically singular and may also include the plural. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the clearly identified steps and elements, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0032] The connection structure of existing fitness equipment is single. For example, a single spur gear is used. Since the gear clearance is prone to getting tight, the effect of quick disassembly and assembly is very unsatisfactory. Another example is that a single bevel gear is used, which is convenient for disassembly and assembly. However, during the force transmission process, the bevel gear is prone to detachment, resulting in loss of force transmission between parallel axes.

[0033] In addition, most existing detachable fitness equipment is disassembled into two sections front and back or folded in a slide rail manner. However, the two-section detachable fitness equipment occupies a large space, and the experience of the slide rail folding type is discounted due to the slide rail folding.

[0034] Therefore, some embodiments of this specification provide a fitness equipment to solve the problems existing in the single connection structure; at the same time, the detachable fitness equipment is disassembled and folded in sections to improve the storage effect and user experience.

[0035] Figure 1 It is an exemplary application scenario diagram of the connection structure shown in some embodiments of this specification.

[0036] Some embodiments of this specification provide a fitness equipment. In some embodiments, the fitness equipment includes a fitness device 10 and a resistance module 20.

[0037] The fitness device 10 refers to the main body part of the fitness equipment.

[0038] In some embodiments, the fitness device 10 includes at least one of a spinning bike, an elliptical machine, and a treadmill.

[0039] The resistance module 20 is a component in the fitness equipment for providing resistance or load. The resistance module 20 is adjustable, enabling the user to adjust the resistance according to different training intensities and goals.

[0040] In some embodiments, the resistance module 20 includes an electric resistance component. The electric resistance component uses a motor to provide resistance or load. The electric resistance component can precisely control the magnitude of the resistance applied to the user, and the adjustment of the resistance magnitude can be achieved by adjusting the rotational speed or torque of the motor.

[0041] In some embodiments, the fitness device 10 and the resistance module 20 can be detachably connected through a connection structure. In some embodiments, as Figure 1 shown, the connection structure includes a first connecting gear 101 and a second connecting gear 102. One end of the first connecting gear 101 is provided with a first guiding structure 1011, and one end of the second connecting gear 102 is provided with a second guiding structure 1021. The first guiding structure 1011 cooperates with the second guiding structure 1021 for guiding, and the first connecting gear 101 and the second connecting gear 102 are connected in a mating manner. For the connection structure, reference can be made to the relevant description later.

[0042] Figure 2 is an application scenario diagram of the installation structure shown in some embodiments of this specification. Figure 3 is an exemplary structural diagram of the installation structure shown in some embodiments of this specification.

[0043] In some embodiments, as Figure 2 shown, the fitness equipment further includes an installation structure 30.

[0044] The installation structure 30 is a structure for installing the fitness device 10 and the resistance module 20 as a whole.

[0045] In some embodiments, as Figure 3 shown, the installation structure 30 includes a first connecting buckle 301 and a second connecting buckle 302. The first connecting buckle 301 is provided on the fitness device 10, and the second connecting buckle 302 is provided on the resistance module 20. The first connecting buckle 301 and the second connecting buckle 302 can be snap-connected. The snap-connection method can be various. For example, the first connecting buckle 301 and the second connecting buckle 302 are snap structures and are snap-connected through a snap. Another example is that the first connecting buckle 301 and the second connecting buckle 302 can be magnetic components and are snap-connected through magnetic adsorption. The first connecting buckle 301 and the second connecting buckle 302 can also be snap-connected in other ways.

[0046] In some embodiments, the number of the first connecting buckles 301 is 2, and the 2 first connecting buckles 301 are respectively buckled on both sides of the fitness device 10. In some embodiments, the number of the second connecting buckles 302 is 2, and the 2 second connecting buckles 302 are respectively buckled on both sides of the resistance module 20.

[0047] In some embodiments, before the fitness device 10 and the resistance module 20 are installed, the first connecting buckle 301 and the second connecting buckle 302 are separated; after the fitness device 10 and the resistance module 20 are installed as a whole, the first connecting buckle 301 and the second connecting buckle 302 are buckled and connected, so as to fix the fitness device 10 and the resistance module 20.

[0048] In some embodiments, as Figure 1 shown, the connecting structure includes a first connecting gear 101 and a second connecting gear 102.

[0049] A gear is a mechanical element with a toothed profile. The material of the gear can be a metal material. The teeth of one gear mesh with the teeth of another gear, so as to realize the transmission of motion or force between two shafts. Gears are used to convert speed, torque or change the direction of motion.

[0050] The first connecting gear 101 is a gear connecting component located on the resistance module 20. The second connecting gear 102 is a gear connecting component located on the fitness device 10. For more descriptions about the resistance module 10 and the fitness device 20, reference can be made to the foregoing content.

[0051] Figure 4 is an exemplary connection sectional view of the connecting structure shown in some embodiments of this specification. Exemplarily, as Figure 4 shown, the fitness device and the resistance module can be connected through the first connecting gear 101 on the resistance module and the second connecting gear 102 on the frame, so as to form a usable fitness equipment.

[0052] Figure 5 is an exemplary structural schematic diagram of the connecting structure shown in some embodiments of this specification.

[0053] In some embodiments, as Figure 5 shown, the first connecting gear 101 is a straight-tooth external gear, and the second connecting gear 102 is a straight-tooth internal gear. In some embodiments, the straight-tooth external gear meshes with the straight-tooth internal gear, so as to realize transmission.

[0054] In some embodiments, the teeth of the straight-tooth external gear are located on the outer circumference of the first connecting gear 101, forming an external tooth ring. The teeth of the straight-tooth external gear are in a straight line shape and parallel to the central axis of the first connecting gear 101.

[0055] In some embodiments, the teeth of the spur internal gear are located on the inner circumference of the second connecting gear 102, forming an internal gear ring. The teeth of the spur internal gear are in a straight line shape and parallel to the central axis of the second connecting gear 102.

[0056] In some embodiments, the tooth profiles of both the spur external gear and the spur internal gear are straight lines. When the spur external gear meshes with the spur internal gear, the tooth profiles of the spur external gear and the spur internal gear are in linear contact with each other to achieve force transmission.

[0057] By using the spur structure to realize the transmission between the first connecting gear and the second connecting gear, the impact and vibration during the transmission can be reduced, the transmission efficiency can be enhanced, so that the transmission stability can be ensured, and during the process of transmitting force through parallel axes, the gears are not easily disengaged.

[0058] In some embodiments, when the first connecting gear 101 and the second connecting gear 102 are meshed, the axes of the first connecting gear 101 and the second connecting gear 102 coincide. The tooth profiles of both the first connecting gear 101 and the second connecting gear 102 are set to be straight lines. During meshing, the tooth surfaces of the first connecting gear 101 and the second connecting gear 102 are in linear contact to achieve smooth force transmission.

[0059] In some embodiments, the first connecting gear 101 and the second connecting gear 102 can achieve precise axial alignment through methods such as machining and assembly accuracy.

[0060] In some embodiments, the first connecting gear 101 and the second connecting gear 102 can be installed on bearings or bushings. The bearings or bushings can provide support for the gears and maintain the relative positions and alignment of the gears.

[0061] In some embodiments, the first connecting gear 101 can be key-connected to the bearing or bushing. For example, a flat key, a spline or other types of keys are used to circumferentially fix the spur external gear to the bearing or bushing, thereby preventing the spur external gear from undergoing relative sliding during the force transmission process. At the same time, the second connecting gear 102 can be connected by positioning pins to ensure the accurate position of the spur internal gear during installation.

[0062] In some embodiments, the first connecting gear 101 and the second connecting gear 102 can be adjusted for clearance, so as to optimize the transmission performance and reduce noise or vibration. For example, the first connecting gear 101 and the second connecting gear 102 can be regularly measured manually. If the axial clearance is greater than the first preset value, the position of the bearing housing is adjusted to adjust the axial clearance; if the radial clearance is greater than the second preset value, the meshing depth is changed by moving the position of one or two teeth, so as to achieve the adjustment of the radial clearance. The first preset value and the second preset value can be set according to experience.

[0063] In some embodiments, such as Figure 1 and Figure 5 shown, one end of the first connecting gear 101 is provided with a first guiding structure 1011, and one end of the second connecting gear 12 is provided with a second guiding structure 1021. The first guiding structure 1011 cooperates with the second guiding structure 1021 for guiding.

[0064] The guiding structure is used to guide, position or fix other components to ensure their correct positions and directions in the moving or static state.

[0065] The first guiding structure 1011 is a structure for guiding, positioning or fixing the first connecting gear 101. The second guiding structure 1021 is a structure for guiding, positioning or fixing the second connecting gear 102.

[0066] In some embodiments, the first guiding structure 1011 and the second guiding structure 1021 are gear structures.

[0067] In some embodiments, the first guiding structure 1011 is coaxially arranged with the first connecting gear 101; the second guiding structure 1021 is coaxially arranged with the second connecting gear 102.

[0068] By setting the first guiding structure and the second guiding structure to cooperate for guiding, when installing the first connecting gear and the second connecting gear, it is possible to quickly guide to make the straight tooth surfaces mesh with each other. When disassembling the first connecting gear and the second connecting gear, it is possible to achieve quick disassembly through the guidance of the first guiding structure and the second guiding structure.

[0069] In some embodiments, such as Figure 5 shown, the first guiding structure 1011 is a bevel external gear, and the second guiding structure 1021 is a bevel internal gear.

[0070] The tooth profile of the bevel gear is conical, and the tooth line is helical or linear along the axis direction of the gear. The tooth profile of the bevel gear gradually decreases from the large end to the small end, forming a conical surface. The bevel gear can be used for axial force transmission or axial positioning.

[0071] In some embodiments, the tooth line of the bevel external gear is located outside the first guiding structure 1011; the tooth line of the bevel internal gear is located inside the second guiding structure 1021. The bevel external gear forms an external tooth ring outside the first guiding structure 1011; the bevel internal gear forms an internal tooth ring inside the second guiding structure 1021.

[0072] In some embodiments, the bevel internal gear and the bevel external gear cooperate, which can guide the first connecting gear and the second connecting gear to automatically correct and quickly engage and connect, and can achieve quick disassembly by using the inclination of the cone when disassembling.

[0073] In some embodiments, the maximum cross-section of the bevel external gear is the same as the cross-section of the straight external gear; the minimum cross-section of the bevel internal gear is the same as the cross-section of the straight internal gear.

[0074] The maximum cross-section of the bevel external gear refers to the section with the largest external tooth profile dimensions in the section perpendicular to the axis of the first guiding structure 1011. The tooth profile of the straight external gear is a straight line distributed along the outer circumference of the gear.

[0075] The minimum cross-section of the bevel internal gear refers to the section with the smallest internal tooth profile dimensions in the section perpendicular to the axis of the second guiding structure 1021. The tooth profile of the straight internal gear is a straight line distributed along the inner circumference of the gear.

[0076] In some embodiments, the tooth line of the bevel external gear continues the tooth line of the straight external gear, and the tooth line of the bevel internal gear continues the tooth line of the straight internal gear.

[0077] By making the maximum cross-section of the bevel external gear the same as the cross-section of the straight external gear, and the minimum cross-section of the bevel internal gear the same as the cross-section of the straight internal gear, it can ensure that two different types of gears can mesh smoothly. At the same time, the above design enables the bevel gear to have a smooth transition point when meshing with the straight gear, reducing meshing impact, noise, and vibration.

[0078] In some embodiments, the taper of the bevel external gear and the bevel internal gear is a preset value.

[0079] The taper refers to the degree of inclination of the tooth profile of the bevel gear. The taper can be expressed as the tooth profile inclination angle measured along the gear axis direction. The taper affects the contact characteristics and meshing performance of the gear. For example, the larger the taper, the larger the contact area, thus improving the uniformity of load distribution and load-carrying capacity to a certain extent. Another example is that the smaller the taper, the better the meshing performance. The preset value can be set according to actual needs. For example, the preset value can be 10°, 20°, or 30°, etc.

[0080] In some embodiments, the ratio of the axial length of the bevel external gear to the axial length of the straight external gear is a preset ratio.

[0081] The ratio of the axial length of the bevel external gear to the axial length of the straight external gear can affect the fitting and transmission characteristics of the gear. The preset ratio can be set according to requirements. For example, the preset ratio can be 15:1, 20:1, or 30:1, etc.

[0082] In some embodiments, the number of teeth of the first connecting gear 101 and the number of teeth of the second connecting gear 101 are preset numbers. By way of example, the number of teeth of the first connecting gear 101 and the number of teeth of the second connecting gear 101 are each 16. In some embodiments, the preset numbers can also be set according to requirements. For example, the preset numbers can be 18, 20, etc.

[0083] The number of teeth affects the gear transmission efficiency and torque transmission capacity. Since there is a certain amount of energy loss at each gear meshing point, the more teeth there are, the lower the gear transmission efficiency. The number of teeth is directly proportional to the torque transmission capacity. More gears can share a greater torque load, reducing the load on a single gear, thereby improving the reliability and durability of the transmission system.

[0084] Setting a reasonable number of teeth can meet different requirements for transmission efficiency and torque transmission capacity. Multi-gear transmission may require a larger installation space and more precise design and manufacturing. Setting different numbers of teeth can meet different space and layout requirements.

[0085] Some embodiments of this specification include but are not limited to the following beneficial effects: (1) Improving transmission efficiency and smoothness: By combining the use of bevel gears and straight gears, the impact and vibration during transmission can be reduced, thereby enhancing the transmission efficiency and improving the overall smoothness of the transmission. At the same time, it helps to reduce energy loss and improve the fluency of mechanical operation; (2) Convenient disassembly and assembly performance: Utilizing the conical surface shape of the bevel gear, it can be quickly guided to the mating straight tooth surface during installation to achieve parallel connection. The conical guiding structure simplifies the assembly process, making the disassembly and assembly of the gears faster and more convenient; (3) Reducing gear clearance problems: The design of the bevel gear helps to automatically correct during disassembly and assembly, reducing the tightness problem caused by the clearance of the straight tooth gear, thereby improving the effect of quick disassembly and assembly; (4) Preventing force transmission loss: When the bevel gear is used alone, it may become disengaged during the force transmission process. By combining it with the straight gear, the possibility of such disengagement can be reduced, ensuring the effective transmission of force and reducing transmission loss; (5) Optimizing the mechanical structure design: The combined design of the bevel gear and the straight gear provides an optimized mechanical structure solution that can adapt to different application scenarios and requirements, enhancing the applicability and flexibility of the mechanical system; (6) Improving the reliability of the system: By reducing impact and vibration, and ensuring the effective transmission of force, it helps to improve the reliability and durability of the entire mechanical system.

[0086] It should be noted that the above description of the connection structure and its components is only for convenience of description and does not limit this specification to the scope of the exemplified embodiments. It can be understood that for those skilled in the art, after understanding the principle of this connection structure, they may combine or adjust each component without departing from this principle.

[0087] Figure 6 It is an exemplary structural diagram of a detachable fitness device shown according to some embodiments of this specification.

[0088] Figure 7 It is another exemplary structural diagram of a detachable fitness device shown according to some embodiments of this specification.

[0089] In some embodiments, as Figure 6 shown, the fitness device includes a first component 100 and a second component 200 that are detachably connected.

[0090] The first component 100 is a part of the fitness device. The second component 200 is the remaining part of the fitness device. The first component 100 and the second component 200 can be connected or separated from each other. Exemplary connection methods include connection by bolts and nuts, connection by quick pins, connection by snaps and slots, connection by rotary locks, etc. In some embodiments, the first component 100 can be folded and unfolded.

[0091] In some embodiments, the fitness device includes a use state and a storage state. Exemplarily, as Figure 6 shown, the fitness device is in the use state, the first component 100 is in the unfolded state, the first component 100 and the second component 200 are in the connected state, and the fitness device in the use state can be used by the user. Exemplarily, as Figure 7 shown, the fitness device is in the storage state, the first component 100 is in the folded state, and the first component 100 and the second component 200 are separated.

[0092] In some embodiments, as Figure 6 shown, the first component 100 includes a mounting rod 110, a first support rod 120, and a first folding mechanism 130.

[0093] The mounting rod 110 is a rod-shaped member for connecting the first component 100 and the second component 200. The first support rod 120 is a support rod located at the front section of the first component 100. The first folding mechanism 130 is a component for realizing the folding function. In some embodiments, the first folding mechanism 130 is located between the mounting rod 110 and the first support rod 120.

[0094] In some embodiments, the mounting rod 110 and the first support rod 120 are folded and unfolded through the first folding mechanism 130.

[0095] Figure 8 It is an exemplary structural diagram of the first folding mechanism shown according to some embodiments of this specification.

[0096] Figure 9 It is another exemplary structural diagram of the first folding mechanism shown according to some embodiments of this specification.

[0097] In some embodiments, asFigure 8 As shown, the first folding mechanism 130 includes a first mounting member 131 and a second mounting member 132.

[0098] The first mounting member 131 is the mounting member on the first folding mechanism 130 that is close to the mounting rod 110. The second mounting member 132 is the mounting member on the first folding mechanism 130 that is close to the first support rod 120. The first mounting member 131 and the second mounting member 132 can be metal plates.

[0099] In some embodiments, as Figure 8 shown, the first mounting member 131 is connected to the mounting rod 110, and the second mounting member 132 is connected to the first support rod 120. In some embodiments, the first mounting member 131 and the second mounting member 132 are rotatably connected, so as to be able to drive the first support rod 120 and the mounting rod 110 to rotate respectively, thereby realizing the folding and unfolding of the first assembly 100.

[0100] In some embodiments, as Figure 8 shown, the first folding mechanism 130 further includes a first operating member 133 and a positioning pin 134.

[0101] The first operating member 133 is an operable component on the first folding mechanism 130. The user can control the relative rotation of the first mounting member 131 and the second mounting member 132 by operating the first operating member 133, thereby controlling the relative rotation of the first support rod 120 and the mounting rod 110.

[0102] The positioning pin 134 is a mechanical element used to limit the relative position of the first mounting member 131 and the second mounting member 132. The positioning pin 134 can ensure that the first mounting member 131 and the second mounting member 132 maintain the correct position and alignment, and prevent the first mounting member 131 and the second mounting member 132 from displacing during movement or when subjected to force.

[0103] In some embodiments, as Figure 8 shown, the positioning pin is movably inserted through the first mounting member 131 and the first operating member 133.

[0104] In some embodiments, the first operating member 133 drives the positioning pin 134 to move between a first position and a second position. The first position and the second position are the relative positions of the positioning pin 134 on the first mounting member 131 and the second mounting member 132.

[0105] In some embodiments, as Figure 9 shown, when the positioning pin 134 is in the first position, the first folding mechanism 130 is in the first folded state. In some embodiments, as Figure 8 shown, when the positioning pin 134 is in the second position, the first folding mechanism 130 is in the first unfolded state.

[0106] The first component can fold and unfold the front section of the fitness equipment through the installation rod, the first support rod, and the first folding mechanism, thereby effectively saving space.

[0107] Figure 10 It is an exemplary exploded view of the first folding mechanism shown in some embodiments of this specification.

[0108] In some embodiments, as Figure 10 shown, the second mounting member 132 is provided with a first positioning groove 1321 and a second positioning groove 1322. The first positioning groove 1321 and the second positioning groove 1322 are grooves or holes located at different positions on the second mounting member 132. One side of the second mounting member 132 close to the first mounting member 131 is provided with an arc structure, and the second mounting member 132 can rotate around the center of the arc. The first positioning groove 1321 and the second positioning groove 1322 are respectively opened at different positions on the arc.

[0109] In some embodiments, as Figure 10 shown, the second mounting member 132 includes two first positioning grooves 1321 and two second positioning grooves 1322, which are respectively oppositely arranged on both sides of the second mounting member 132.

[0110] In some embodiments, the first positioning groove 1321 and the second positioning groove 1322 can cooperate with the positioning pin 134. The sizes of the first positioning groove 1321 and the second positioning groove 1322 match the size of the positioning pin 134. The positioning pin 134 can be engaged in the first positioning groove 1321 or the second positioning groove 1322. When the positioning pin 134 is located in the first positioning groove 1321, the first folding mechanism 130 is in the first folding state. Operating the first operating member 133, the positioning pin 134 exits from the first positioning groove 1321, and the first mounting member 131 and the second mounting member 132 rotate relative to each other. The positioning pin 134 is engaged with the second positioning groove 1322. At this time, the first folding mechanism 130 is in the first unfolded state.

[0111] The first positioning groove 1321 and the second positioning groove 1322 can provide accurate positioning points to ensure that the second mounting member 132 and the first mounting member 131 maintain the correct position and alignment.

[0112] In some embodiments, as Figure 10 shown, the first mounting member 131 is provided with a first long hole 1311, and the positioning pin 134 is inserted through the first long hole 1311, and the positioning pin 134 can move along the first long hole 1311.

[0113] The first long hole 1311 is a through hole on the first mounting member 131. In some embodiments, as Figure 10 shown, the first mounting member 131 includes two first long holes 1311, and the two first long holes 1311 are oppositely arranged on both sides of the first mounting member 131.

[0114] In some embodiments, the positioning pin 134 is sized and shaped to match the first elongated hole 1311. The length of the first elongated hole 1311 is greater than the cross-sectional length of the positioning pin 134, thereby allowing the positioning pin to be inserted into the first elongated hole 1311 and move along the length direction of the first elongated hole 1311.

[0115] The first elongated hole can lock or release the first component at different positions of the positioning pin, realizing the folding or unfolding function of the first folding mechanism.

[0116] In some embodiments, such as Figure 8 and Figure 10 shown, the first folding mechanism includes a guide pin 135.

[0117] The guide pin 135 is a mechanical element for guiding the movement of the first operating member 133. The guide pin 135 can guide the first operating member 133 along a predetermined trajectory direction, helping the positioning pin 134 to unlock from the positioning groove, thereby preventing the first operating member 133 from shifting or jamming due to different user operations.

[0118] In some embodiments, the guide pin 135 is movably inserted through the first mounting member 131 and the first operating member 133. In some embodiments, the guide pin 135 is a cylindrical or conical pin.

[0119] In some embodiments, the first mounting member 131 is provided with a second elongated hole 1312, and the guide pin 135 is inserted through the second elongated hole 1312, and the guide pin 135 can move along the second elongated hole 1312.

[0120] The second elongated hole 1312 is a through hole on the first mounting member 131 with a different position from the first elongated hole 1311. In some embodiments, such as Figure 10 shown, the first mounting member 131 includes two second elongated holes 1312, and the two second elongated holes 1312 are oppositely arranged on both sides of the second elongated hole 1312.

[0121] In some embodiments, the size and shape of the guide pin 135 match the second elongated hole 1312. The length of the second elongated hole 1312 is greater than the cross-sectional length of the guide pin 135, thereby allowing the guide pin 135 to be inserted into the second elongated hole 1312 and move along the length direction of the second elongated hole 1312.

[0122] In some embodiments, such as Figure 8 and Figure 10 shown, the first folding mechanism further includes a tension spring member 136.

[0123] The tension spring member 136 is a component for providing elastic force. In some embodiments, the tension spring member 136 is an elastic component. For example, the tension spring member 136 can be a helical spring, a torsion spring, or other types of elastic components, etc. The shape of the tension spring member 136 can be designed according to the required magnitude and direction of the elastic force and the application scenario, etc.

[0124] In some embodiments, as Figure 8 shown, one end of the tension spring member 136 is fixed to the first mounting member, and the other end is fixed to the positioning pin 134.

[0125] In some embodiments, the tension spring member 136 can cooperate with the positioning pin 134 and the first operating member 133. For example, operating the first operating member 133 to overcome the elastic force of the tension spring member 134 drives the positioning pin 134 to move in the first long hole 1311. The positioning pin 134 is unlocked from the positioning groove, and the positioning pin 134 moves along the arc of the second mounting member 132 until it enters the next positioning groove, and the positioning pin 134 is locked to the positioning groove under the elastic force of the tension spring member 136.

[0126] Exemplarily, in the first unfolded state, as Figure 8 shown, the positioning pin 134 is located at the second position and cooperates with the second positioning groove 1322, so that the first mounting member 131 and the second mounting member 132 cannot move relative to each other, and the relative position of the first strut 120 and the mounting rod 110 is fixed, enabling the first assembly 100 to maintain the unfolded state.

[0127] Exemplarily, in the first folded state, Figure 9 shown, the positioning pin 134 is located at the first position and cooperates with the first positioning groove 1321, so that the first mounting member 131 and the second mounting member 132 cannot move relative to each other, and the relative position of the first strut 120 and the mounting rod 110 is fixed and in an overlapping state, enabling the first assembly 100 to maintain the folded state.

[0128] Exemplarily, in the first unfolded state, operating the first operating member 133 causes the guide pin 135 to move along the second long hole 1312 and the positioning pin 134 to move along the first long hole, so that the positioning pin is pulled out of the second positioning groove 1322, unlocking the first mounting member 131 and the second mounting member 132. At this time, the first strut 120 and the mounting rod 110 can rotate relative to each other; during the rotation process of the first strut 120 and the mounting rod 110 along the overlapping direction, the positioning pin 134 moves from the second position to the first position, and the positioning pin 134 cooperates with the first positioning groove 1321, so that the first mounting member 131 and the second mounting member 132 cannot move relative to each other, and the relative position of the first strut 120 and the mounting rod 110 is fixed, enabling the first folding mechanism to be in the first folded state. Conversely, the first folding mechanism can be operated from the first folded state to the first unfolded state.

[0129] Figure 11 It is an exemplary structural diagram of the second folding mechanism shown in some embodiments of this specification. Figure 12 It is an exemplary partial structural diagram of the second folding mechanism shown in some embodiments of this specification. Figure 13 It is another exemplary partial structural diagram of the second folding mechanism shown in some embodiments of this specification.

[0130] In some embodiments, the first component 100 includes a second folding mechanism 140.

[0131] In some embodiments, as Figure 11 and Figure 12 shown, the second folding mechanism 140 includes a second support rod 141, a third support rod 142, an operable second operating member 143, and a mating member 144.

[0132] The second support rod 141 is a rod-shaped structural member connected to the mounting rod 110. The third support rod 142 is a rod-shaped structural member at the end of the second folding mechanism 140.

[0133] The second operating member 143 is an operable structural member, for example, a toggle switch, etc.

[0134] The mating member 144 is a structural member used in cooperation with the second operating member 143, for example, a toggle switch buckle.

[0135] In some embodiments, the second support rod 141 and the third support rod 142 are movably connected, the second support rod 141 is connected to the second operating member 143, and the third support rod 143 is connected to the mating member 144. In some embodiments, the second operating member 143 and the mating member 144 are operably mated or separated. Exemplarily, as Figure 12 shown, the second operating member 143 and the mating member 144 are mated; as Figure 13 shown, the second operating member 143 and the mating member 144 are separated.

[0136] In some embodiments, when the second operating member 143 and the mating member 144 are mated, the second folding mechanism 140 is in the second unfolded state; when the second operating member 143 and the mating member 144 are separated, the second folding mechanism 140 is in the second folded state.

[0137] In some embodiments, the user can separate the second operating member 143 from the mating member 144 by operating the second operating member 143. At this time, the second rod 141 and the third rod 142 can rotate relative to each other within a certain range. The second rod 141 and the third rod 142 can rotate around the overlapping direction. The second folding mechanism 140 is in the second folded state, which is convenient for storage. When the second operating member 143 is engaged with the mating member 144, the second rod 141 and the third rod 142 are relatively fixed, and the second folding mechanism 140 is in the second unfolded state, which can keep the fitness device in a stable structural state during use.

[0138] Figure 14 is another exemplary partial structural view of the second folding mechanism shown in some embodiments of this specification.

[0139] In some embodiments, as Figure 14 shown, the second folding mechanism 140 further includes a fixed shaft 145.

[0140] The fixed shaft 145 is a mechanical element for supporting and providing a rotation center. In some embodiments, the second rod 141 and the third rod 142 can rotate around the fixed shaft 145.

[0141] In some embodiments, the fixed shaft 145 can be fixedly installed on the frame or bracket. In some embodiments, the fixed shaft 145 can be detachably installed on the frame or bracket for easy maintenance and replacement.

[0142] In some embodiments, as Figure 14 shown, the second folding mechanism 140 further includes a connecting block 146.

[0143] The connecting block 146 is a component for connecting the second rod 141 and the third rod 142. The connecting block can be made of a material with good mechanical properties. Good mechanical properties can include high strength, wear resistance and corrosion resistance, so that the second folding mechanism 140 can adapt to different working environments.

[0144] In some embodiments, the shape and size of the connecting block can be set according to requirements to adapt to different connection requirements and space limitations. In some embodiments, the shape and size of the connecting block can match the second rod 141 and the third rod 142, so as to ensure reliable connection between the second rod 141 and the third rod 142.

[0145] The connecting block helps to align and position the second rod 141 and the third rod 142, prevent the second rod 141 and the third rod 142 from shifting or misaligning during use, and ensure that the relative positions between the second rod 141 and the third rod 142 meet the design requirements. Thus, the stability of the mechanical structure of the second folding mechanism 140 is enhanced.

[0146] In some embodiments, the second folding mechanism 140 can complete the conversion from the second unfolded state to the second folded state by the following operations: toggle the second operating member 143 to separate the second operating member 143 from the matching member 144, press the third support rod 142 to rotate the third support rod 142 around the fixed axis in a direction close to the second support rod 141 to the second folded state. The operation of converting the second folding mechanism 140 from the second folded state to the second unfolded state is similar.

[0147] The second folding mechanism can make the fitness equipment take up less space when not in use, and can be quickly unfolded when needed, thus providing convenience and practicality.

[0148] The detachable fitness equipment described in some embodiments of the present specification may include but is not limited to the following beneficial effects: (1) Through the detachable and foldable design, the space occupied by the fitness equipment when not in use is greatly reduced, which is convenient for storage and suitable for homes or gyms with limited space; (2) Users can easily disassemble and assemble the fitness equipment, making it more convenient to move or carry; (3) The design of the first component allows the mounting rod and the first support rod to be folded and unfolded through the first folding mechanism, and the fitness equipment can adapt to a variety of exercise methods or be adjusted to different usage configurations.
