[0012] Figure 1 This is a perspective view of an embodiment of the present utility model.
[0013] Figure 2 This is a cross-sectional schematic diagram of an embodiment of the present utility model.
[0014] Figure 3 This is a three-dimensional schematic diagram of the rotating seat according to an embodiment of the present utility model. Detailed Implementation
[0015] like Figure 1 —— Figure 3 A hybrid tensioning pulley, as shown, includes a mounting bracket 2 with a rotating hole 1. The mounting bracket 2 is rotatably mounted on a rotating seat 3. The rotating seat 3 includes an annularly arranged wheel mounting panel 301 and a hollow turntable 302. The turntable 302 is rotatably connected to the rotating hole 1. A torsion spring mounting cavity 4 is provided between the wheel mounting panels 301, and a torsion spring 5 is provided within the torsion spring mounting cavity 4. One end of the torsion spring 5 abuts against the mounting bracket 2, and the other end abuts against the rotating seat 3. The wheel mounting panel 301 has a wheel 6, which is eccentrically positioned relative to the rotation axis of the rotating seat 3. The mounting bracket 2 has a first torsion spring abutment 7 capable of abutting one end of the torsion spring 5. The rotating seat 3 is the end face of the wheel mounting panel 301 facing the mounting bracket 2. A second torsion spring abutment 8 is provided, which can abut the other end of the torsion spring 5. The second torsion spring abutment 8 includes a torsion spring through groove 801 provided on the rotating seat 3.
