[0016] Embodiment 1

[0017] Attached Figure 1 —As shown in Figure 3, a rope winding and pressing structure of a strength training machine includes a mounting base plate, a motor, a pulling rope, a motor adapter plate, a wire winding device, and a wire pressing device; the wire winding device includes a wire winding wheel 11, a wire winding wheel bracket 3, and a wire outlet 5. The middle of the wire winding wheel 11 is cylindrical, with wire blocking plates provided at both ends. A wire winding wheel shaft 2 is provided in the center. A bearing 9 is installed on each of the wire winding wheel shafts 2, and the bearing 9 is fixed on the wire winding wheel bracket 3 with a bearing seat. The wire winding wheel bracket 3 is fixed on the mounting base plate 1. Along the axial direction of the wire winding wheel 11, a wire outlet 5 is provided at the upper end of the wire winding wheel bracket 3. The pulling rope 6 is wound around the wire winding wheel 11 and extends out from the wire outlet 5; the wire pressing device is two wire pressing elastic pieces 4 fixed on both sides of the wire outlet and unfolded along the axial direction of the wire winding wheel; the motor 8 is fixed on the motor adapter plate 7, the motor adapter plate 7 is fixed on the wire winding wheel bracket 3 with bolts, and the shaft of the motor 8 is concentric with the wire winding wheel 11 and is connected and fixed to the inner hole provided in the center of the wire winding wheel shaft with a flat key.

[0018] A spiral wire groove 10 for winding the pulling rope 6 is provided on the surface of the cylindrical section in the middle of the wire winding wheel.

[0019] The wire pressing elastic piece 4 is pressed against the surface of the pulling rope 6 in the middle of the winding wheel 11, and its width is greater than the width of the spiral groove 10 on the winding wheel 11.

[0020] The wire outlet 5 is made of a long strip of thick plate and is horizontally fixed at the upper end of the winding wheel bracket 3, and an opening equal in length to the spiral groove 10 of the winding wheel is provided thereon.
