Summary of the invention
Shortcoming for prior art, the object of the present invention is to provide a kind of by simple insertion and taking-up, allow the dismounting of accessory use easier connection fittings and the application of connection part and connection part thereof thereof, make continuous link block form coaxial deflection with a certain specified angle, to adapt to different Environmental Conditions, and the link block that links to each other is in the situation of the lateral external forces effect that is gone beyond the limit, can self adaption produce relatively rotation, thereby avoid the destruction under limit load, original coaxial deflection angle in the time of after limit lateral external forces disappears, static state can being returned to simultaneously.
To achieve these goals, technological scheme of the present invention is: a kind of connection fittings comprise the groove of the main body that is cylindrical shape, the through hole that is positioned at main center's axle position, main body one end and the waveform curved-surface structure of the main body the other end.
Further, described groove is crossing distribution at main body one end, perhaps according to the supporting design of the shape of connection part.
Further, described waveform curved surface is the curved surface that is generated by the smoothed curve that the cycle changes.
Further, described waveform curved surface has equally distributed a plurality of crest and trough.
Further, described waveform curved surface is the curved surface that is generated by sinusoidal curve, and described is 0.1～2.0 by wave height and wavelength ratio in the curved surface one-period of sinusoidal curve generation.
Further, described waveform curved surface has equally distributed four crests and trough, and the cross line of described groove and the cross of four crest peaks are wired to a certain deflection angle, and this deflection angle can be 0～360 °.
A kind of application of connection fittings, comprise two connection fittings and two connection parts, described connection fittings comprise main body, the through hole that is positioned at main center's axle position that is cylindrical shape, the waveform curved-surface structure of being located at the groove of main body one end and being located at the main body the other end, and described connection part comprises the flanged structure that matches with groove; Described two connection parts are serially connected by two connection fittings, and two connection fittings are connected by the waveform curved surface, and two connection parts are connected in respectively the groove at two connection fittings two ends by flanged structure.
Further, described two connection parts become a certain axial deflection angle, thereby change the penetrating rate of entire system, or the entire system regularity of distribution.
Further, described waveform curved surface is the curved surface that is generated by the smoothed curve that the cycle changes.
Compared with prior art, the present invention has the following advantages: when two connection fittings of the present invention are subject to homocentric axial force, axially be along connection fittings in the waveform curved end and stablize the closed butt joint state, the assembly that is connected axially becomes a certain deflection angle along connection fittings, thereby change the penetrating rate of entire system, or the entire system regularity of distribution; When assembly is subject to perpendicular to the automobile parts center axle and during with the not coplanar limit lateral external forces of central shaft, the waveform curved surface of the connection fittings of docking can produce relative rotational slide, after limit lateral external forces disappears, the waveform curved surface can return to the closed butt joint state under axial force, the assembly that simultaneously assurance is connected remains unchanged to deflection angle along the axial axis of connection fittings.
