Abstract
The present disclosure provides an anti-jamming ratchet-type tensioning device, which comprises a base which is provided with a winding and unwinding mechanism, wherein the winding and unwinding mechanism comprises a ratchet wheel with gear teeth, and the base is further provided with an operating mechanism; and the winding and unwinding mechanism can be selectively locked or unlocked by the operating mechanism; and the operating mechanism is rotatably connected with a lever element having two opposite ends, which are respectively configured as a pressing end and an executing end.
Claims19
An anti-jamming ratchet-type tensioning device, comprising a base which is provided with a winding and unwinding mechanism, wherein the winding and unwinding mechanism comprises a ratchet wheel with gear teeth, wherein
- the base is further provided with an operating mechanism, and the winding and unwinding mechanism is selectively locked or unlocked by the operating mechanism;
- and
- the operating mechanism is rotatably connected with a lever element having two opposite ends, which are respectively configured as a pressing end and an executing end;
- and
- the executing end is provided with an elastic check claw located within a rotation radius of the ratchet wheel for preventing the ratchet wheel from rotating back;
- and
- the operating mechanism is provided with a support element, the lever element is provided with a movement area, and the support element extends into the movement area;
- and
- an accommodating area of the movement area is larger than that of the support element, and the support element is allowed to move in the movement area;
- and
- the pressing end and the executing end form a lever by taking take the support element as a fulcrum and, wherein when the pressing end is pressed, the executing end tilts, and the elastic check claw is located outside the rotation radius of the ratchet wheel.
