Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 As shown, a connection fitting includes a cylindrical main body 11, a through hole 14 located at the central axis 17 of the main body 11, a groove 12 at one end of the main body, and a wavy curved surface 13 at the other end of the main body. One end of the main body 11 is distributed in a cross shape, and the wavy curved surface 13 is a curved surface generated by a periodically changing smooth curve, and has a plurality of crests and troughs evenly distributed; in this embodiment, a curved surface generated by a sinusoidal curve has a uniform Take the four peaks and troughs of the distribution as an example.
[0020] The ratio of the wave height to the wavelength within a sine cycle of the wavy surface 13 is 0.1 to 2.0; a groove cross reference line 15 corresponding to the cross-shaped groove 12 and a cross line 16 at the highest points of ...

The invention discloses a connecting fitting which comprises a cylindrical main body, a through hole, a groove and a wavy curved surface structure, wherein the through hole is positioned at the central shaft of the main body; the groove is arranged at one end of the main body; and the wavy curved surface structure is arranged at the other end of the main body. The invention also discloses an application of the connecting fitting. In the application, two connecting fittings and two connecting assemblies are utilized, wherein each connecting assembly comprises a flange structure which is matched with the groove; the two connecting assemblies are connected in series through the two connecting fittings; the two connecting fittings are meshed through the wavy curved surfaces; and the two connecting assemblies are respectively connected to grooves which are at two ends of two connecting fittings through the flange structure. By utilizing the fitting provided by the invention, a device whichis poor in coaxial rotation angle is bad and has a self-adaptive capability to a horizontal force is formed, connected modules generate relative rotation under the condition that the connected modules are subjected to a limitation lateral force, and simultaneously the original angle difference can be recovered when the limitation lateral force vanishes.
Description
technical field [0001] The invention relates to the fields of machinery industry and marine engineering structure, in particular to a connection fitting and its application. Background technique [0002] In the field of engineering, it is often necessary for some accessories to produce an angle difference around the axis on the same axis. Most of the existing connection accessories provide rigid connections. Specifically, the whole device is rigid after the two components are connected by connecting fittings, and the components or connecting fittings will generate internal stress when subjected to lateral external force. Unrecoverable deformation or even fracture occurs due to the increase, resulting in failure of the entire device. Contents of the invention [0003] Aiming at the shortcomings of the prior art, the object of the present invention is to provide a connection fitting and its connection assembly and its application of the connection assembly which are easier...
