[0033] The linkage inclined lever 73 is fixedly sleeved on the driving shaft 714 of the support shaft seat 71 at the front end and rotatably connected to the T-shaped sliding seat 721-2 at the rear end, so that the first shaft seat 711, the first inclined lever 721 and the linkage inclined lever 73 form a triangular linkage structure.

[0034] The Z-shaped rocker 74 is integrally connected to the driving shaft 714 of the support shaft seat 71 and provides external driving force for the rotation of the driving shaft 714.

[0035] The physical training equipment with easy-to-adjust seat posture of the present case has the working principle or operation process as follows:

[0036] 1. When the user steps on the Z-shaped rocker 74, the driving shaft 714 rotates and drives the linkage inclined lever 73, the linkage inclined lever 73 rotates around the driving shaft 714 as the pivot, and then drives the T-shaped sliding seat 721-2 to slide in the T-shaped sliding slot, so as to drive the lifting inclined lever 72 to rotate around the hinge shaft 713 as the pivot, finally making the roller 723 at the rear end of the lifting inclined lever 72 descend and contact the ground, and lifting the rear part of the equipment.

[0037] 2. When the rear of the equipment is raised, the rear of the equipment is in a suspended state.

This mechanism includes a support shaft forming a triangular linkage structure, a lifting lever, a linkage lever, and a foot-operated Z-shaped rocker arm that provides driving force to the triangular linkage structure. When the user steps on the Z-shaped rocker arm, the rear of the equipment is raised into the air, allowing the user to easily adjust and lock the insertion depth of the docking sleeve within the docking sleeve. This adjusts the seat's fore-and-aft distance to meet the needs of people of different heights, making the adjustment simple and effortless.

[0039] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
