Detailed Implementation

[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-10As shown, a Pilates training device with a novel adjustable structure includes a bed frame 1. A rope frame 2 is installed on one side of the bed frame 1, and a lifting pulley 3 is provided inside the rope frame 2. The lifting pulley 3 is used to connect the lifting rope. The lifting pulley 3 is adjustable in height inside the rope frame 2 via a lifting mechanism 4. A handrail 5 is installed on the other side of the bed frame 1. The two ends of the handrail 5 are rotatably connected to the bed frame 1 via a pivot 6. A rotation adjustment limiting mechanism 7 is provided between the handrail 5 and the bed frame 1 to limit the rotation angle of the handrail 5.

[0031] This utility model, through the design of the rotation adjustment limiting mechanism 7, allows for the rotational adjustment of the handrail angle during actual use to suit different exercise needs. Furthermore, through the lifting mechanism 4, the height of the lifting pulley 3 can be adjusted. The adjustment operation is convenient and has wider applicability. Users can freely adjust the angle of the handrail and the height of the lifting pulley according to the exercise program or their own needs.

[0032] The rotation adjustment and limiting mechanism 7 includes a rotating sleeve 8 installed at the lower end of the armrest 5. One end of the rotating shaft 6 is connected to the bed frame 1, and the other end of the rotating shaft 6 extends out of the bed frame 1 and is provided with a limiting member 9. The rotating sleeve 8 is installed on the outer periphery of the limiting member 9. The rotating sleeve 8 can be rotatably sleeved on the outer periphery of the limiting member 9, thereby realizing the rotational connection between the two.

[0033] A limiting ring 10 is also provided between the rotating sleeve 8 and the limiting member 9. A spring 11 abuts against one side of the limiting ring 10 and the rotating sleeve 8, and a button cover 12 is installed on the other side of the limiting ring 10. A limiting pin 13 is installed on the inner circumference of the limiting ring 10. Several slots 14 for the limiting pin 13 to be engaged are opened in the circumferential direction of the limiting member 9. The spring 11, through its own elasticity, keeps the limiting pin 13 moving closer to the slot 14. Without external force, the limiting pin 13 remains against the slot 14, thereby limiting the movement of the limiting pin 13. The relative rotation between the limiting ring 10 and the limiting member 9 is controlled, thereby keeping the handrail 5 in a fixed state. When it is necessary to adjust the angle of the handrail 5, the limiting ring 10 can be pushed inward by pressing the button cover 12, thereby driving the limiting pin 13 to move away from the slot 14. At this time, the limiting between the limiting ring 10 and the limiting member 9 is released, and the angle of the handrail 5 can be adjusted. After releasing the button, the limiting pin 13 can be automatically locked into the slot 14 by the elastic force of the spring, achieving an automatic fixing effect.

[0034] The inner side of the limiting member 9 is formed with a snap-fit ​​part 15, and the side of the bed frame 1 is provided with a snap-fit ​​groove 16 for the snap-fit ​​part 15 to snap into, so as to restrict the rotation of the limiting member 9 and keep the limiting member 9 fixedly installed so that the limiting pin can be snapped in.

[0035] The rotating sleeve 8 has a rear end cover 17 installed on one side and a front end cover 18 installed on the other side, thereby sealing the two ends of the rotating sleeve 8 and effectively preventing external dust from entering. The inner side of the front end cover 18 is connected to the limiting ring 10, and the outer side of the front end cover 18 is equipped with a button cover 12. The spring 11 abuts between the rear end cover 17 and the front end cover 18.

[0036] The rear end cover 17 is provided with a plurality of guide shafts 19 in the circumferential direction. The front end cover 18 and the limiting ring 10 are respectively provided with guide grooves 20 for fitting around the guide shafts 19, thereby improving the stability of the front end cover 18 and the limiting ring 10 when moving. During the rotation of the handrail 5, the front end cover 18 and the limiting ring 10 will be rotated around the limiting member 9 by the rotating sleeve 6, the rear end cover 17, and the guide shafts 19, and at the same time, the limiting pin 13 will be moved so that it is engaged in the slot 14.

[0037] The inner side of the button cover 12 is formed with a snap-fit ​​part 21, and the front cover 18 is provided with a snap-fit ​​hole 22 for the snap-fit ​​part 21 to be snapped into. The assembly and connection are achieved by snap-fit, which makes it easy to assemble and disassemble.

[0038] The lifting mechanism 4 includes a lifting seat 23, which has an installation cavity 24 for mounting the lifting pulley 3. A clearance space is provided between the upper and lower ends of the lifting pulley 3 and the installation cavity 24 for the lifting rope to extend. An adjusting shaft 25 is transversely inserted into the installation cavity 24. The lifting pulley 3 is rotatably mounted on the outer periphery of the adjusting shaft 25. One end of the adjusting shaft 25 extends out of the lifting seat 23 and the slot 28 and is screwed with an adjusting knob 26. The rope frame 2 has an adjusting cavity 27 formed inside for the lifting seat 23 to move up and down. A slot 28 is provided on the side of the adjusting cavity 27. In actual adjustment, after loosening the adjusting knob 26, the adjusting knob 26 can be pushed up and down, causing the lifting seat 23 to move up and down within the adjusting cavity 27 via the adjusting shaft 25, thereby adjusting the up and down position of the lifting pulley 3. After tightening the adjusting knob 26, it can be pressed against the end face of the rope frame 2 to fix the position.

[0039] The inner side of the adjustment knob 26 is formed with a circular limiting part 29. The strip groove 28 is provided with a plurality of circular limiting holes 30 for the circular limiting part 29 to be inserted. After the adjustment knob 26 is turned in, the circular limiting part 29 can be inserted into the circular limiting hole 30, restricting its movement and fixing the position of the adjustment knob 26, thereby achieving the effect of fixing the position of the lifting seat 23.

[0040] The outer wall of the lifting seat 23 is formed with a circular limiting groove 31 for the circular limiting part 29 to abut against. The outer periphery of the adjusting knob 26 is formed with a number of anti-slip protrusions 32. A bearing 33 is provided between the lifting pulley 3 and the adjusting shaft 25.
