RATCHET BUCKLE

摘要

A ratchet buckle, which is configured to connect a first strap and a second strap, includes a controlling device, an operating device connected to the first strap, a reel passing through the controlling device and the operating device along an axial line, the second strap wound around the reel, at least one ratchet set mounted on the reel, the reel being not rotated relative to the ratchet set, and a pawl device. When the user wants to unwind the second strap from the reel, the user moves and rotates the controlling device smoothly with only one hand thereof; therefore, it's very convenient for the user to operate. The special structure making the ratchet set unidirectionally rotatable, and it doesn't need any further structure, so that it is lighter and has lower cost.

1. A ratchet buckle, which is configured to connect a first strap and a second strap, comprising:
a controlling device; an operating device connected to the first strap; a reel passing through the controlling device and the operating device along an axial line, the second strap wound around the reel; a pawl device having a first through hole and at least one first pawl member, the first through hole formed on the operating device therethrough, along the axial line, the reel passing through the through holes, the first pawl member defined on an inner wall of the first through hole; and at least one ratchet set mounted on the reel, the reel being not rotated relative to the ratchet set, at least a portion of the ratchet set received in the first through hole, the ratchet set movable in the first through hole via an outer force, between a first position under which the first pawl member is engaged with the ratchet set so that the ratchet set is rotatable in one direction, and a second position under which the first pawl member is disengaged from the ratchet set so that the ratchet set is rotatable in one direction or the other opposite direction.
