Summary of the invention

The utility model technical problem to be solved is that a kind of effective baffler clip of automobile exhaust of good sealing effect is provided.

The technological scheme that the utility model adopted is: a kind of baffler clip comprises outer ring, bridge plate, otic placode, screw bolt and nut; Said outer ring is open setting; The two end part of said outer ring bend two joints that form otic placode outside circumference; Interior Monday of the side of one end of said bridge plate and outer ring is fixed as one; The other end of bridge plate is not have fixing free end in the interior week of outer ring, and it is fastening by nut that said bolt passes the screw hole of otic placode; Also include inner ring, said inner ring is arranged on the side end of the inner peripheral surface of outer ring.

Said inner ring is open, and inner ring one side is formed with groove, and opposite side is formed with the ligulate convexity suitable with groove, the protruding interference fit of said groove and ligulate.

The material of said inner ring is aluminium or soft attitude stainless steel.

The inboard of said outer ring is formed with die-cut convexity.

A kind of baffler clip comprises, outer ring, otic placode, screw bolt and nut; Said outer ring is an Open architecture; The opening of outer ring bends outside circumference and fixes with the outer circumferential face of outer ring respectively and forms first mounting part and second mounting part; Said otic placode is installed in respectively in first mounting part and second mounting part, and it is fastening by nut that said bolt passes the screw hole of otic placode; Inner ring is arranged on the whole inner peripheral surface of outer ring.

One side of said inner ring is formed with 2 grooves, and opposite side is formed with 2 the ligulate convexities suitable with groove.

The beneficial effect of the utility model is: because inner ring is installed; The protruding interference fit of inner ring groove and ligulate makes the caliber mouth of automobile exhaust pipe produce uniform fastening force on every side, and good sealing effect; Controlled formed slit in the installation preferably; This baffler clip technology is simple, easy to make, adaptable across the fastening of pipe fitting be connected.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:

Embodiment 1: the utility model diameter reducing type baffler clip comprises outer ring 10, inner ring 20, bridge plate 30, otic placode 40, bolt 50 and nut 60; Said outer ring 10 is open setting; The two end part of said outer ring 10 bend two joints that form otic placode 40 outside circumference; Interior Monday of the side of one end of said bridge plate 30 and outer ring 10 is fixed as one; Interior week of 10 is not have fixing free end to the other end of bridge plate 30 in the outer ring, and it is fastening by nut 60 that said bolt 50 passes the screw hole of otic placode 40; Said inner ring 20 is open, and a side of said inner ring 20 is formed with groove 21, and opposite side is formed with the suitable ligulate of groove 21 protruding 22, said groove 21 and protruding 22 interference fit of ligulate; Inner ring 20 is arranged on the side end of the inner peripheral surface of outer ring 10, is fixed by die-cut protruding 13 of the inboard formation at 10 these places, outer ring; The material of said inner ring 20 is aluminium or soft attitude stainless steel, and soft material can make inner ring and outer ring that stronger combination force is arranged, and can realize better sealing effect.

The working principle of the utility model baffler clip is: when bolt is fastened when moving; The diameter of clip diminishes; In the protruding groove that gets on the inner ring of the ligulate of inner ring, inner ring is combined closely all the time with the outer ring, producing around the caliber mouth has uniform fastening force; Produce the better seal effect, effectively controlled formed gap in the installation.

Embodiment 2: the utility model latus rectum formula baffler clip comprises outer ring 10, otic placode 40, bolt 50 and nut 60; Said outer ring 10 is an Open architecture; The opening of outer ring 10 bends outside circumference and fixes with the outer circumferential face of outer ring 10 respectively and forms first mounting part 11 and second mounting part 12; Said otic placode 40 is installed in respectively in first mounting part 11 and second mounting part 12, and it is fastening by nut 60 that said bolt 50 passes the screw hole of otic placode 40; Inner ring 20 is open; The width of clip inner ring is identical with the width of outer ring, and clip inner ring one side is formed with groove 21, because wider width; 2 grooves can be set; Simultaneously also be 2 with the suitable ligulate convexity of groove, groove 21 and protruding 22 interference fit of ligulate, inner ring 20 is arranged on the whole inner peripheral surface of outer ring 10.Its working principle is identical with embodiment 1, repeats no more at this.
