Abstract

The invention discloses a mechanical splice comprising two main bodies, two sleeves and a bushing, wherein the bushing is arranged in the bore of the two main bodies arranged symmetrically, and the two sleeves are sheathed on the periphery of the main bodies; a stepped excircle I, a shaft shoulder, a stepped excircle II and a stepped excircle III are arranged on the periphery of the main bodies in turn from front to back, and the shaft shoulder is raised and annular, and is provided with a triangular, concave and annular drop-proof slot; a cylindrical surface I, a conical surface I, a cylindrical surface II, a conical surface II and a drop-proof ring are arranged in the bores of the sleeves from small ends to big ends in turn, the bushing is cylindrical, the middle part is thick and both sides are thin; the middle of the outside surface of the bushing is provided with a triangular annular bulge. The diameter, volume and weight of the mechanical splice disclosed by the invention are reduced obviously, so that the space occupation and total weight of a pipeline system are reduced, which is especially important for those aviation and aerospace fields with high requirements for the volume and weight.

Description

technical field

[0001] The invention belongs to the technical field of pipeline connection, and more specifically relates to a mechanical joint. Background technique

[0002] The existing mechanical joint jacket and main body have no detachment prevention structure, and the outer surface of the bush has no teeth, so the connection is not firm enough to adapt to higher pressure occasions, and leakage will occur when the medium pressure exceeds 10 MPa. Contents of the invention

[0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a mechanical joint with high pressure resistance that exceeds the existing joints.

[0004] The technical solution adopted by the mechanical joint of the present invention is to include two main bodies, two jackets and a bushing, the bushing is arranged in two symmetrically arranged inner holes of the main body, and the two jackets are respectively put on the outer periphery of th...
