Buckle device
A buckle device includes a seat body, a belt body having saw-toothed sections, and a control member. An actuating portion and a linkage portion of the control member are pivotally connected to the seat body through a rotating shaft. The actuating portion and the linkage portion are provided with a first return elastic member and a second return elastic member, respectively. The tops and the bottoms of the actuating portion and the linkage portion are provided with raised blocks and raised teeth to engage with the saw-toothed sections, respectively. The user can pull the actuating portion with one hand for the raised teeth of the actuating portion and the linkage portion to disengage from the saw-toothed sections.
1. A buckle device, comprising:
a seat body, the seat body being formed with a passage, the passage having two side walls each formed with a perforation, a first retaining bar and a second retaining bar being provided at respective inner sides of the two side walls respectively;
a belt body, the belt body being inserted through the passage, the belt body including a plurality of saw-toothed sections thereon; and
a control member, one end of the control member being pivotally connected to the seat body, the control member including:
an actuating portion, the actuating portion having a notch, a first groove and a pair of first through holes at two sides of the notch, a first raised block and at least one first raised tooth corresponding to the saw-toothed sections of the belt body being provided on a top and a bottom of the actuating portion respectively;
a linkage portion, the linkage portion being disposed in the notch of the actuating portion and formed with a second through hole and a second groove, a second raised block and at least one second raised tooth corresponding to the saw-toothed sections of the belt body being provided on a top and a bottom of the linkage portion respectively;
a rotating shaft, inserted through the perforations of the two side walls of the seat body, the first through holes of the actuating portion and the second through hole of the linkage portion;
a first return elastic member, two ends of the first return elastic member being connected to the first retaining bar and the first groove of the actuating portion respectively; and
a second return elastic member, two ends of the second return elastic member being connected to the second retaining bar and the second groove of the linkage portion respectively.
2. The buckle device as claimed in claim 1 , wherein the first return elastic member and the second return elastic member are torsion springs.
3. The buckle device as claimed in claim 1 , wherein the second raised block of the linkage portion has a height greater than that of the first raised block of the actuating portion.
