[0028] The sliding limiting structure 5 of this embodiment can slide along the circumference toward the first limiting boss 31 through the first sliding groove 41, thereby allowing the second limiting boss 51 to overlap with the first limiting boss 31 in the axial direction. The second limiting boss 51 is staggered from the first limiting boss 31, meaning that in a normal state, the position of the first limiting boss 31 corresponds to the position of the second sliding groove 71 of the cross bar 7, while the position of the second limiting boss 51 is staggered from the position of the second sliding groove 71 of the cross bar 7, thereby achieving both limiting and fixing functions.

[0029] In this embodiment, under normal conditions, Figure 3 and Figure 4 As shown, the first limiting boss 31 of the protective sleeve 3 and the second limiting boss 51 of the sliding limiting structure 5 are staggered, and then through the action of the second sliding groove 71 and the card slot 72, the first end cover 1, the movable ring assembly 2, the protective sleeve 3, the second end cover 4 and the sliding limiting structure 5 are fixed to the cross bar 7 as a whole, as shown in FIG. Figure 7 When the position of the force point needs to be adjusted, the sliding limit structure 5 slides along the circumference toward the first limit boss 31 through the first slide groove 41, so that the second limit boss 51 can overlap with the first limit boss 31 in the axial direction. At this time, the position of the movable ring assembly 2 on the cross bar 7 can be adjusted, and after the adjustment, the reset second limit boss 51 is limited and fixed by the clamping groove 72.

[0030] Therefore, this embodiment can quickly and efficiently adjust the force point during fitness, and can improve the flexibility and adaptability of the cross bar structure through the optimized design of the cross bar structure to meet different fitness needs. After adjusting the position of the force point, it can also quickly and stably achieve the limiting and fixing functions, effectively improving the humanized design and safety performance of the product.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, preferably, this embodiment further includes a reset spring 6 , which is disposed at one end of the first sliding groove 41 and is in contact with the sliding limiting structure 5 . When the cam 51 is in the closed position, the first stop 51 is in the closed position, and the second stop 51 is in the closed position, so that the cam 51 is in the closed position and the stop 51 is in the closed position.

[0032] Therefore, through the reset spring 6, the force point adjustment process of the cross bar structure can be faster and more efficient, and through the reset spring 6, the limiting stability between the second limiting boss 51 and the slot 72 can be better guaranteed, thereby improving the safety performance of the product.

[0033] Preferably, in this embodiment, the cross-sectional dimension of the second limiting boss 51 is smaller than or equal to the cross-sectional dimension of the first limiting boss 31 , so that in the compressed state, the second limiting boss 51 can better enter the second slide groove 71 and move in the second slide groove 71 .

[0034] Preferably, Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8As shown, in this embodiment, the first limiting boss 31 and the second limiting boss 51 are both V-shaped bosses, and the second chute 71 is a V-shaped chute that matches the V-shaped boss. Through such a structural design, it is more conducive to the smooth adjustment of the force application point position.

[0035] As Figure 5 and Figure 7 shown, in this embodiment, the number of the card slots 72 is multiple, and the multiple card slots 72 are arranged at intervals on the cross bar 7. Therefore, according to different fitness needs, the overall limiting and fixing effects on the first end cover 1, the movable ring assembly 2, the protective sleeve 3, the second end cover 4, the sliding limiting structure 5 and the return spring 6 can be realized at different positions. The number and positions of the card slots 72 can be set according to the actual situation.

[0036] Preferably, as Figure 5 shown, in this embodiment, the limiting direction of the card slot 72 is perpendicular to the direction of the second chute 71. For example, if the direction of the second chute 71 is the same as the direction of the cross bar 7, then the limiting direction of the card slot 72 is perpendicular to the direction of the cross bar 7, so as to better ensure the limiting and fixing effects after the adjustment of the force application point.

[0037] As Figure 1 shown, in this embodiment, the movable ring assembly 2 includes a rotating ring 21, a connecting piece 22 and a hanging ring 23. The hanging ring 23 is connected to the rotating ring 21 through the connecting piece 22, and the rotating ring 21 is arranged between the first end cover 1 and the protective sleeve 3; the rotating ring 21 includes a rotating ring inner ring structure 211, and the second end cover 4 is provided with an outer circular structure 42 that matches the rotating ring inner ring structure 211, and the rotating ring inner ring structure 211 is rotatably connected to the outer circular structure 42, so as to realize the connection between the cross bar structure and the fitness equipment through the movable ring assembly 2. The connecting piece 22 can adopt different connecting pieces such as a braided belt.

[0038] As Figure 1 and Figure 2 shown, in this embodiment, the sliding limiting structure 5 is provided with a rotating ring through hole 52, the position of the rotating ring through hole 52 corresponds to the position of the outer circular structure 42, and the rotating ring inner ring structure 211 passes through the rotating ring through hole 52 and the outer circular structure 42, so as to efficiently utilize the existing structure to realize the rotational setting of the movable ring assembly 2.

[0039] More preferably, a plurality of first limiting bosses 31 are provided on the protective sleeve 3 of this embodiment, and the number and positions of the second sliding grooves 71 respectively correspond to the number and positions of the first limiting bosses 31. For example, two first limiting bosses 31 are provided on the protective sleeve 3, and the two first limiting bosses 31 are respectively provided at the top and bottom of the protective sleeve 3. Correspondingly, as Figure 9 shown, one corresponding second sliding groove 71 is also provided at the top and bottom of the cross bar 7, so as to further increase the safety of the product through the structural design of double-sliding groove sliding connection, and during the process of adjusting the force application point position, it can also be more smooth, stable and reliable.

[0040] Preferably, as Figure 1 and Figure 2 shown, a pressing end 53 inclined to both sides is provided at the top of the sliding limit structure 5 of this embodiment. Through this design of the pressing end 53 inclined to both sides, it can enable the operator to more easily push the sliding limit structure 5, so as to facilitate the adjustment of the position of the force application point. As Figure 1 shown, between the first end cover 1 and the second end cover 4, it is preferably assembled quickly through structures such as screws and studs.
