Further, the plug division of the first pipe is 5mm to 10mm along axial length, holding edge axial direction
Length is not less than the length of the plug division, so that holding side tightly after the insertion of plug division can be with fully wrapped around plug division.
The assembly method of above-mentioned plug-in type adjustable exhaust pipe connection structure, includes the following steps:
A, by the trapezoidal cyclic annular asbestos cushion cover in section in the cavity of first pipe front end 7 font protrusion.
B, by the plug division insertion second pipe of first pipe front end, plug division, which is placed in, is held tightly in side and before plug division
End carries out blocking limit by transition side, avoids insertion excessive；The top of the tubaeform flanging of second pipe and 7 fonts are convex at this time
The outboard end for playing annular sidewall is in contact, and to close cavity, asbestos pad is limited in cavity, flanging is to asbestos pad
Sloped sidewall is squeezed to form sealing, and joint leaks are reduced.
C, by hoop sleeve in the joint of first pipe and second pipe, so that second pipe flanging, 7 word of first pipe
The sloped sidewall of shape protrusion is placed in clip, locking hoop, is fixed at butt joint, and sealing effect is reinforced.
The technical effect of invention: (1) of the invention plug-in type adjustable exhaust pipe connection structure and its assembly method, relatively
It in the prior art, is matched using the 7 font protrusions and flanging that are circumferentially arranged, so that 7 font protrusions and second pipe outer wall
Between formed and can place the cavity of asbestos pad, effectively increase the thickness of asbestos pad, improve the service life of asbestos pad so that
The air-tightness of exhaust pipe is guaranteed during integeral vehicle life；(2) first pipe and second pipe are connected using plug-in type
It connects, plug division and holds clearance fit between side tightly and holding fixation is carried out using anchor ear, so that error radial when assembly is by embracing
Hoop is made up, it is ensured that assembly precision.
