Embodiment:
Below in conjunction with accompanying drawing and preferred embodiment, dual-axis differential formula trigger architecture embodiment, structure, feature and effect thereof to foundation the present invention proposes are described in detail as follows.
Referring to Fig. 1 to Fig. 3, dual-axis differential formula trigger architecture of the present invention, comprise axle I, axle II, housing 1, wherein: axle I is comprised of ring flange 3, support 4, the end of ring flange 3 is connected with housing 1 by bearings D 11, and support 4 one ends are connected with ring flange 3, the other end is connected with housing 1 by bearing B5; Axle II is comprised of sleeve 7, metal slip ring 9, axle 10, sleeve 7 is fixed in the end thread hole of axle 10 by bolt 8, metal slip ring 9 is set on the axle 10, the axle 10 at metal slip ring 9 two ends respectively by bearing C6 be connected with support 3 one end endoporus, bearing A2 is connected with ring flange 3 endoporus, metal slip ring 9 outer circumference surfaces are provided with collets 12.
During use, referring to Fig. 4 to Fig. 6, at the ring flange 3 fixed installation conducting rings 15 of axle I, with conducting ring 15 with respect to cover plate 14 on fixed installation contact spring leaf 13; Fixed installation electric contact piece 16 on the support 4.Axle II is nested on the axle I, all can freely rotate around central axis.Metal slip ring 9 outer circumference surfaces are provided with collets 12, metal slip ring 9 is divided for non-metallic areas and metallic conduction district along circumference, be installed in the front end of the electric contact piece 16 on the support 4, be overlapped on the central authorities of the non-metallic areas of metal slip ring 9, be in the no signal output state this moment.Conducting ring 15 respectively be installed in cover plate 14 on contact spring leaf 13 contact conducting, by being installed in the wire output electrical signals that links to each other with contact spring leaf 13 on the cover plate 14.
