Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Embodiment one: shown in accompanying drawing 1-5.
A kind of atp synthase model teaching aid, comprise rotating part and support portion, rotating part comprises axostylus axostyle 2, inserts lobe ball 13, the first spheroid 6, the second spheroid 7, slotting lobe ball 13, the first spheroid 6, the second spheroid 7 are set on the axostylus axostyle 2 from top to bottom successively, the support portion comprises axostylus axostyle pedestal 3, connecting link pedestal 9, crooked connecting link 8, is arranged on the heading 1 on connecting link 8 tops, connecting link 8 is symmetricly set on connecting link pedestal 9 outside surfaces, axostylus axostyle 2 tops are rotationally connected with heading 1, and axostylus axostyle 2 lower ends and axostylus axostyle pedestal 3 are rotationally connected.
Atp synthase model teaching aid assembling mode: axostylus axostyle 2 bottoms are installed in the bearing of axostylus axostyle pedestal 3 center pits 16; Be inserted in the second spheroid 7, the first spheroid 6 at axostylus axostyle 2 successively, the strip card article 14 on the fashionable draw-in groove aligning axostylus axostyle that makes in the first spheroid 6, the second spheroid 7 of cover; Big-small plug lobe successively interval is installed on the axostylus axostyle 2; To head a ball and 1 be installed in axostylus axostyle 2 tops; Two connecting links 8 are installed in connecting link pedestal 9 both sides; At last the buckle of reserving in the heading 1 being inserted on connecting link 8 tops gets final product.
