[0014] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The mechanisms in the drawings are not drawn to scale, and similar mechanism symbols are commonly used to represent similar mechanisms.

[0015] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0016] Reference Figure 1-4 This embodiment provides a foldable bottom tube structure for fitness equipment, including a connecting seat 1, a first bottom tube 2, a second bottom tube 3, and a locking / unlocking mechanism 4. The first bottom tube 2 has a first end 21 and a second end 22 along its length, with the first end 21 pivotally connected to the connecting seat 1; the first end 21 is provided with a first engaging portion 23. The second bottom tube 3 has a third end 31 and a fourth end 32 along its length, with the third end 31 pivotally connected to the connecting seat 1; the third end 31 is provided with a second engaging portion 33 capable of engaging with the first engaging portion 23. The locking / unlocking mechanism 4 is mounted on the connecting seat 1 and includes a positioning portion 41 and an operating component 42. At least one of the first engaging portion 23 and the second engaging portion 33 has a positioning hole 5. The operating component 42 is used to drive the positioning portion 41 to insert or retract from the positioning hole 5 to lock or unlock the positional relationship between the first bottom tube 2, the second bottom tube 3, and the connecting seat 1; thereby ensuring the stability of the foldable bottom tube structure during use of the fitness equipment and improving the safety performance of the fitness equipment.

[0017] In this embodiment, a positioning hole 5 is provided only on the first engaging portion 23. Thus, by simply inserting the positioning part 41 into the positioning hole 5 on the first engaging portion 23, the positional relationship between the first bottom tube 2, the second bottom tube 3, and the connecting seat 1 can be locked. Furthermore, based on the required locking angle between the first bottom tube 2 and the second bottom tube 3, only one positioning hole 5 is provided in this embodiment. When the positioning part 41 is inserted into the positioning hole 5, the first bottom tube 2 and the second bottom tube 3 extend to their maximum angle around their respective pivot axes. Of course, in other embodiments, positioning holes 5 can be provided on both the first engaging portion 23 and the second engaging portion 33, and the number of positioning holes 5 can be set according to actual needs.

[0018] In this embodiment, a first pivot shaft 11 and a second pivot shaft 12 are arranged side by side on the connecting seat 1. The first end 21 of the first bottom tube 2 is pivotally sleeved on the first pivot shaft 11, and the third end 31 of the second bottom tube 3 is pivotally sleeved on the second pivot shaft 12.

[0019] In this embodiment, a first arc-shaped block 231 with a toothed edge is integrally connected to the outer wall of the first end 21 of the first bottom tube 2, serving as the first meshing part 23. The center of the first arc-shaped block 231 coincides with the pivot axis of the first bottom tube 2. A second arc-shaped block 331 with a toothed edge is integrally connected to the third end 31 of the second bottom tube 3, serving as the second meshing part 33, with its center coinciding with the pivot axis of the second bottom tube 3. Through the mutual meshing of the first arc-shaped block 231 and the second arc-shaped block 331, rotating one of the first bottom tube 2 and the second bottom tube 3 will drive the other to rotate. In other embodiments, an annular block with a toothed edge can also be used as the meshing part according to actual needs.

[0020] In this embodiment, the operating component 42 includes a base 421, a rotating pressure rod 422, and an elastic element 423. The base 421 is fixed to the edge of the connecting seat 1. A third pivot shaft 4211 is provided on the base 421, and the middle position of the rotating pressure rod 422 is pivotally connected to the third pivot shaft 4211. The two ends of the rotating pressure rod 422 along its length are the operating end 4222 and the positioning end 4221, respectively. In this embodiment, the positioning part 41 is a rod-shaped structure. The positioning part 41 is connected to the positioning end 4221 of the rotating pressure rod 422. The elastic element 423 is used to provide a force that drives the positioning end 4221 of the rotating pressure rod 422 to press down toward the positioning hole 5. By setting the elastic element 423, the relative stability between the positioning part 41 and the positioning hole 5 can be maintained, and the positioning part 41 can be prevented from disengaging from the positioning hole 5 due to external forces during the use of the fitness equipment. The operating end 4222 can be pressed down by an external force, so that the positioning end 4221 swings upward around the third pivot axis 4211, thereby causing the positioning part 41 to exit the positioning hole 5, thereby releasing the positional relationship between the first bottom tube 2, the second bottom tube and the connecting seat 1, and the first bottom tube 2 and the second bottom tube 3 can be folded.

[0021] In this embodiment, the elastic element 423 includes a torsion spring 4231, which is sleeved on the third pivot shaft 4211, and its two ends abut against the rotating pressure rod 422 and the base 421, respectively. The torsion spring 4231 acts on the lower surface between the middle of the rotating pressure rod 422 and the force-applying end, so that the positioning end 4221 of the rotating pressure rod 422 always has a downward pressing tendency. In other embodiments, the elastic element 423 can also be a spring, with its two ends abutting against the rotating pressure rod 422 and the base 421, but this arrangement requires a spring with greater elastic force to maintain the relative stability between the positioning part 41 and the positioning hole 5.

[0022] In this embodiment, the connecting seat 1 is provided with a partition 13. The first bottom tube 2 and the second bottom tube 3 are configured such that when the first bottom tube 2 and the second bottom tube 3 are in a folded state, they are parallel to each other and located on both sides of the partition 13. The partition 13 is located on the side of the connecting seat 1 away from the locking and unlocking mechanism 4.

[0023] In this embodiment, both the second end 22 of the first bottom tube 2 and the fourth end 32 of the second bottom tube 3 are provided with support feet 6.

[0024] This embodiment also provides a fitness device, including the above-described foldable bottom tube structure.

[0025] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
