[0031] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0032] In the description of this disclosure, unless otherwise stated, "inner" and "outer" refer to the inner and outer contours of the corresponding components. Furthermore, the terms "first," "second," etc., are used to distinguish one element from another and do not have any order or importance.

[0033] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connect," "link," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0034] like Figures 1 to 3 As shown, this disclosure provides a training frame for a multifunctional fitness equipment, including a main support frame 10, two adjustable frames 20, and two adjusting components 30. The main support frame 10 includes a support frame 11 and two support frame assemblies 12 oppositely arranged on the support frame 11. The two support frame assemblies 12 and the support frame 11 together enclose a cavity 13. The two adjustable frames 20 are rotatably connected to the ends of the two support frame assemblies 12 away from the support frame 11. Each adjusting component 30 is used to adjust the angle between the plane where the adjusting frame 20 is located and the plane where the corresponding support frame assembly 12 is located.

[0035] Among them, the support frame 11 is the core structural component of the training rack, providing stable support for the entire device.

[0036] Two support frame assemblies 12 are arranged opposite to each other on the support frame 11, and together with the support frame 11, they form a cavity 13, which can be used to place equipment or as an area for users to stand in.

[0037] Through the above technical solution, the adjustable components 30 are used to adjust the position of their corresponding adjustable frame 20. This means that users can adjust the angle between the plane of the adjustable frame 20 and the plane of the support frame assembly 12 using the adjustable components 30 according to their training goals and personal comfort, achieving the best training effect. This training frame is suitable for various types of training, including strength training, stretching, and balance exercises. The training frame provided in this disclosure is not only compact but also highly flexible and adaptable to different training needs. With simple adjustments, users can choose the appropriate configuration for their training plan.

[0038] As one implementation method, such as Figure 1As shown, the training frame also includes a pull-up mechanism 40 and two variable resistance systems 50. Each variable resistance system 50 includes a handle 51, a cable 52, a pulley system 53, and a counterweight assembly 54. The two counterweight assemblies 54 are respectively mounted on two support frame assemblies 12. The two handles 51 are respectively mounted on two adjustable frames 20 and connected to the corresponding counterweight assemblies 54 via corresponding cables 52 and pulley systems 53. Each adjustable frame 20 has a closed position, a neutral position, and an extended position. In the closed position, the two adjustable frames 20... The planes where the 0 are located are perpendicular to the planes where the corresponding support frame group 12 is located, so as to cover the cavity 13; in the middle position, the planes where the two adjustment frames 20 are located coincide with the planes where the corresponding support frame group 12 is located, one end of the pull-up mechanism 40 is rotatably connected to one of the two adjustment frames 20, and the other end of the pull-up mechanism 40 is detachably connected to the other of the two adjustment frames 20; in the extended position, the planes where the two adjustment frames 20 are located are set at an obtuse angle to the planes where the corresponding support frame group 12 is located, so as to expose the cavity 13.

[0039] The adjustable frame 20, through the adjustable component 30, allows the adjustable frame 20 to rotate relative to the support frame assembly 12 to a closed position, a neutral position, and an extended position. In the closed position, the adjustable frame 20 rotates until its plane is perpendicular to the plane of the support frame assembly 12. At this position, the two adjustable frames 20 work together to cover the cavity 13, effectively closing the cavity 13 area like a double door. This means that when not exercising, the user can rotate the two adjustable frames 20 to the closed position, reducing the space occupied by the training frame, making it more compact and easier to store. In the neutral position, each adjustable frame 20 is on the same plane as its corresponding support frame assembly 12. At this position, both ends of the pull-up mechanism 40 can be mounted on the two adjustable frames 20, allowing the user to perform pull-up exercises using the pull-up mechanism 40. In the extended position, each adjustment frame 20 forms an obtuse angle with its corresponding support frame group 12. At this time, the two adjustment frames 20 work together to expose the cavity 13. The two adjustment frames 20 can be unfolded like a double door, facilitating the user to perform fly exercises from high to low using the variable resistance system 50. That is, the user holds one handle 51 in each hand, starts from a high position, and then extends their arms outward, lowering the height of the handles until they are close to the low position. In this way, through simple adjustments, the user can choose the appropriate configuration for their training plan.

[0040] As one implementation method, such as Figures 1 to 3As shown, the support frame assembly 12 includes a first support 121 and a second support 122 arranged vertically. The adjustment frame 20 includes a third support 21, a fourth support 22, and a fifth support 23. The adjustment assembly 30 includes a first adjustment member 31. The third support 21 and the fifth support 23 are respectively connected to both ends of the fourth support 22 and extend in the same direction. The end of the third support 21 away from the fourth support 22 is located below the first support 121 and is hinged to the first support 121. The end of the fifth support 23 away from the fourth support 22 is hinged to the second support 122. The bottom of the first support 121 is shaped like a... The first adjustment part 32 is located between the first support 121 and the third support 21. The first adjustment part 32 has a fan-shaped structure and a plurality of first through holes 321 are formed on the first adjustment part 32. The plurality of first through holes 321 are arranged at intervals along the circumference of the first adjustment part 32. The first adjustment member 31 includes a first limiting rod 311 located below the third support 21. The first limiting rod 311 is movably installed on the third support 21 so that it can be inserted into or removed from the first through hole 321 located above the third support 21.

[0041] The third bracket 21 and the fifth bracket 23 are connected to the first bracket 121 and the second bracket 122 by hinges, which allows the adjustment frame 20 to rotate around these hinge points.

[0042] Specifically, the user can first remove the first limiting rod 311 from the first through hole 321 at the current position, then rotate the adjustment frame 20 to the desired position, and then insert the first limiting rod 311 into the first through hole 321 at the corresponding new position, thereby locking the adjustment frame 20 in the target position. In this way, the user can adjust the angle of the adjustment frame 20 as needed to achieve different exercise postures.

[0043] As one implementation method, such as Figures 2 to 3 As shown, the first adjusting member 31 also includes a mounting shell 312, which is connected to the lower surface of the third bracket 21. The first limiting rod 311 is movably inserted through the mounting shell 312 and the third bracket 21. The end of the first limiting rod 311 away from the third bracket 21 protrudes outward from the mounting shell 312 and forms an operating part 313.

[0044] The first limiting rod 311 can move axially inside the mounting shell 312, with one end protruding outward from the mounting shell 312 to form an operating part 313, which is convenient for user operation.

[0045] The user can move the first limiting rod 311 through the operating unit 313. When it is necessary to adjust the position of the adjusting frame 20, the user can pull the first limiting rod 311 out of the currently inserted first through hole 321, then rotate the adjusting frame 20 to the desired position, and then insert the first limiting rod 311 into the new first through hole 321 to lock the position of the adjusting frame 20.

[0046] The mounting housing 312 provides guidance and support for the first limiting rod 311, ensuring that the first limiting rod 311 can move on the correct track and can be stably inserted into or pulled out of the first through hole 321.

[0047] As one implementation method, such as Figures 2 to 3 As shown, the first adjusting member 31 also includes an elastic member 314. The elastic member 314 is located on the mounting shell 312 and sleeved on the first limiting rod 311. The first end of the elastic member 314 is connected to the first limiting rod 311, and the second end of the elastic member 314 is connected to the inner wall of the mounting shell 312.

[0048] The elastic element 314 can be constructed as a spring structure. The function of the elastic element 314 is to provide restoring force for the first limiting rod 311. When the user releases the first limiting rod 311, the elastic element 314 will push the first limiting rod 311 to automatically insert into the nearest first through hole 321 to lock the position of the adjusting frame 20.

[0049] Specifically, the user can manually move the first limiting rod 311 via the operating unit 313. When the position of the adjusting frame 20 needs to be adjusted, the user can pull the first limiting rod 311 out of the currently inserted first through hole 321, at which point the elastic element 314 is compressed; then rotate the adjusting frame 20 to the desired position, and after releasing the first limiting rod 311, the restoring force of the elastic element 314 will push the first limiting rod 311 to automatically insert into the new first through hole 321, thereby locking the position of the adjusting frame 20. With this design, the user can more easily adjust the position of the adjusting frame 20, while the presence of the elastic element 314 ensures the reliability and stability of the device. In addition, the mounting shell 312, besides serving as a guide structure for the first limiting rod 311, also serves to fix the elastic element 314, ensuring that the elastic element 314 will not shift or fall off during use.

[0050] As one implementation method, such as Figures 2 to 3 As shown, the first limiting rod 311 includes a rod body 3111 and a protrusion 3112 that protrudes radially outward from the rod body 3111. An elastic member 314 is sleeved on the rod body 3111, and the first end of the elastic member 314 is connected to the protrusion 3112.

[0051] Among them, the rod body 3111 is the main insertion component, the protrusion 3112 provides a connection point, and the elastic element 314 is located between the protrusion 3112 and the inner wall of the mounting shell 312. Specifically, the elastic element 314 is sleeved on the rod body 3111, and one end of the elastic element 314 is connected to the protrusion 3112, while the other end of the elastic element 314 is connected to the inner wall of the mounting shell 312. This connection method ensures that the elastic element 314 can stably provide restoring force during use.

[0052] To enhance the reliability of the connection between the adjustment frame 20 and the corresponding support frame assembly 12, as one implementation method, such as Figure 1 As shown, the adjustment assembly 30 also includes a second adjustment member 33. The second bracket 122 includes a first segment 1221 and a second segment 1222, which are arranged at a perpendicular angle. One end of the first segment 1221 is connected to the support frame 11, and the bottom of the other end of the first segment 1221 is connected to the second segment 1222. A groove is formed on the second segment 1222. The end of the fifth bracket 23 away from the fourth bracket 22 is located in the groove and hinged to the groove. A second adjustment part 34 is formed on the bottom of the first segment 1221. The second adjustment part is located on the first segment 1222. Between segment 1221 and the fifth bracket 23, the second adjustment part 34 has a fan-shaped structure. Multiple second through holes are formed on the second adjustment part 34. The multiple second through holes are spaced apart along the circumference of the second adjustment part 34. The second adjustment member 33 includes a connector and a second limiting rod. The first end of the connector is connected to the top of the fifth bracket 23, and the second end of the connector is connected to the second limiting rod. The first limiting rod 311 is pluggably connected to the fifth bracket 23 so that it can be inserted into or removed from the second through hole located above the fifth bracket 23.

[0053] The second adjustment part 34 also adopts a fan-shaped structure with multiple second through holes distributed on it, which are used to adjust the angle of the fifth bracket 23 relative to the second bracket 122.

[0054] The fifth bracket 23 and the second limiting rod are connected by a connector, allowing the second limiting rod to move as the fifth bracket 23 moves. The second limiting rod is used to lock the position of the fifth bracket 23. Different angles of the fifth bracket 23 relative to the second bracket 122 are fixed by inserting it into different second through holes. With this configuration, when the adjusting frame 20 rotates to the target position, the cooperation between the first adjusting member 31 and the second adjusting member 33 can improve the stability of the overall structure.

[0055] Specifically, the user can operate the second limiting rod to pull it out of the current second through hole, adjust the fifth bracket 23 to the desired angle position, and insert the second limiting rod into the new second through hole to lock the position of the fifth bracket 23.

[0056] Optionally, as one embodiment, the second limiting rod includes a rod and a protrusion, one end of the protrusion is connected to the second end of the connector, and the other end of the protrusion is connected to the rod, wherein the radial dimension of the protrusion is greater than the radius of the second through hole.

[0057] Specifically, when the second limiting rod is inserted into the new second through hole, the protrusion effectively prevents the second limiting rod from accidentally dislodging from the second through hole during use, thus increasing the reliability of the locking mechanism of the adjustment frame 20. In other words, the protrusion design ensures that the adjustment frame 20 will not change position due to accidental movement of the second limiting rod during use, thereby improving the overall safety of the fitness equipment.

[0058] Optionally, the connector is constructed as a spring cable structure. This spring cable structure allows for automatic rewinding, reducing clutter and saving space.

[0059] Optionally, such as Figure 1 As shown, the training rack also includes two casters 60 and two bases 70. Each base 70 is used to support the support frame 11 and the corresponding second bracket 122. Each fourth bracket 22 has a caster 60 installed at its bottom.

[0060] The casters 60 allow the entire adjustable frame 20 to rotate easily, making it convenient for users to adjust it to different positions. Additionally, the casters 60 can be equipped with brakes to lock them, preventing unnecessary movement of the training frame during use and thus improving the overall stability of the training frame.

[0061] The base 70 supports the entire training rack, increasing its stability. Especially when performing certain movements that require greater force, the base 70 ensures that the training rack will not shake or move.

[0062] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0064] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
