The specific embodiment
In Fig. 2, show the outward appearance of a safety buckle 10, Fig. 3 is its element decomposing state, and Fig. 4 is its flat shape, and Fig. 5 represents its interior shape, can be for explanation technology contents of the present invention.This safety buckle 10 comprises an intermediate member 20, have the first relative groove cave 21a and the second groove cave 21b, upper surface and the lower surface of this first groove cave 21a respectively have two left-right symmetry, and be in the arc-shaped groove 22a on the same circular arc, the upper surface of the second groove cave 21b and lower surface equally also respectively have two left-right symmetry, and are in the arc-shaped groove 22b on the same circular arc; That is to say that the inner surface of the first groove cave 21a and the second groove cave 21b respectively has four arc-shaped groove 22a and 22b.In fact, last two arc-shaped groove 22a that are symmetrical set in same upper and lower surface and 22b also can connect, and form a continuous arc-shaped groove, are not restricted to the described embodiments.
Another pith of the present invention is the first connector 30a and the second connector 30b that is used for connecting ribbon.Wherein, the first connector 30a comprises one first base portion 31a, has one first 32a with holes, forms the path that pierces into for ribbon (figure does not show) first end, and have one first insertion section 33a and extend forward from the first base portion 31a, it can insert in the first groove cave 21a of intermediate member 20.Again, the upper surface of the first insertion section 33a and lower surface respectively have at least one projection 34a, and in the embodiment of accompanying drawing, the upper and lower lip-deep projection 34a of the first insertion section 33a is two, and is symmetrical set; That is to say, outer surface at the first insertion section 33a has four projection 34a, each projection 34a can corresponding embed in the groove 22a of one first groove cave 21a, so makes the first connector 30a and intermediate member 20 snap close mutually, and can rotate with respect to intermediate member 20 in the angle that groove 22a limits.
Described second connector 30b structure is identical with the first connector 30a, comprise one second base portion 31b, has one second 32b with holes, form the path that pierces into for ribbon second end, and having the forward extension of one second insertion section 33b from the second base portion 31b, it can insert in the second groove cave 21b of intermediate member 20; Again, the upper surface of the second insertion section 33b and lower surface respectively have two projection 34b that are symmetrical set, each projection 34b can correspondingly embed in the groove 22b of one second groove cave 21b, so make the second connector 30b and intermediate member 20 snap close mutually, and can in the angle that groove 22b limits, rotate with respect to intermediate member 20.
In order to support the first connector 30a and the second connector 30b to rotate around intermediate member 20, the front end of the first insertion section 33a and the second insertion section 33b forms a circular arc-shaped recess 35a and a 35b who caves in backward respectively; Circular arc protuberance 23a and 23b that each self-forming one of the bottom of the first groove cave 21a and the second groove cave 21b is outstanding forward, make the first connector 30a and the second connector 30b respectively with intermediate member 20 mutually during snap close, its circular arc-shaped recess 35a and 35b can agree with circular arc protuberance 23a and 23b, make first and second connector 30a and 30b rotate about 60 degree around intermediate member 20 respectively reposefully; That is be that 0 degree is counted with central axis 25, respectively clockwise, rotate counterclockwise 30 degree.Fig. 6 and Fig. 7 show that the first connector 30a and the second connector 30b are respectively with respect to intermediate member 20 clockwise and rotate counterclockwise plane to maximum angle.
Again, the arc-shaped groove 22a of intermediate member 20 2 ends and 22b also can only be located at upper surface or the lower surface of the first groove cave 21a and the second groove cave 21b, in the case, as long as projection 34a on first and second connector 30a and the 30b and 34b also are formed at the upper surface of first and second insertion section 33a and 33b or lower surface, but preferable with the embodiment of accompanying drawing.
The present invention is limited to the foregoing description, and it can be other different kenels.For example, the first groove cave 21a and the second groove cave 21b of above-mentioned intermediate member 20 respectively with the first insertion section 33a of the first connector 30a and the second insertion section 33b transposition of the second connector 30b, so also can be able to be reached the purpose identical with first embodiment.Shown in Fig. 8 to 11, second embodiment that forms according to above-mentioned variation for the present invention.In the present embodiment, the intermediate member 40 of this safety buckle 10a has the first relative insertion section 41a and the second insertion section 41b, and the upper surface of first and second insertion section 41a and 41b and lower surface respectively have two projection 42a and 42b.The first connector 50a comprises one first base portion 51a, has one first 52a with holes, and one first connecting portion 56a extends forward from the first base portion 51a, it defines one first groove cave 53a, the first insertion section 41a that can accept intermediate member 40 inserts, and respectively there are two arc-shaped groove 54a on the upper and lower surface of the first groove cave 53a, the one projection 42a that can accept the first insertion section 41a respectively embeds, make the first connector 50a and intermediate member 40 snap close mutually, and can in the angle that groove 54a limits, rotate with respect to intermediate member 40.The second connector 50b comprises one second base portion 51b, has one second 52b with holes, and one second connecting portion 56b extends forward from the second base portion 51b, it defines one second groove cave 53b, allow the second insertion section 41b of intermediate member 40 to insert, and respectively there are two arc-shaped groove 54b on the upper and lower surface of the second groove cave 53b, the one projection 42b that can accept the second insertion section 41b respectively embeds, make the second connector 50b and intermediate member 40 snap close mutually, and can in the angle that groove 54b limits, rotate with respect to intermediate member 40.
Same, rotating around intermediate member 40 in order to support the first connector 50a and the second connector 50b, a circular arc-shaped recess 43a and a 43b who caves in backward formed respectively on the bottom of the first insertion section 41a and the second insertion section 41b; Circular arc protuberance 55a and 55b that each self-forming one of the front end of the first connecting portion 56a and the second connecting portion 56b is outstanding forward, make the first connector 50a and the second connector 50b respectively with intermediate member 40 mutually during snap close, its circular arc protuberance 55a and 55b can agree with circular arc- shaped recess 43a and 43b, make first and second connector 50a and 50b rotate about 60 degree around intermediate member 40 respectively reposefully; That is be that 0 degree is counted with central axis 45, respectively clockwise, rotate counterclockwise 30 degree.Figure 12 and Figure 13 show that the first connector 50a and the second connector 50b are respectively with respect to intermediate member 40 clockwise and rotate counterclockwise plane to maximum angle.
As described above, according to safety buckle 10 of the present invention (10a), because the first connector 30a (50a) and the second connector 30b (50b) can rotate 60 degree with respect to intermediate member 20 (40) respectively, make to act on this angular range and all can make this safety buckle 10 (10a) automatically terminate snap close, have only a special angle can trip safer compared to above-mentioned known eye-splice with interior pulling force.
Certainly, the foregoing description can not depart from the scope of the present invention down in addition some variations, thus above explanation comprises and accompanying drawing shown in full content should be considered as exemplary, but not in order to limit the present invention.
