Description

Silencer hoop

Technical Field

The utility model relates to the technical field of auto-parts, especially a silencer staple bolt.

Background

At present, the automobile muffler utilizes the connection cushion on two engaging lugs of muffler staple bolt to hang the assembly with whole muffler assembly, however, current muffler staple bolt carries out closed fastening through the bolt, like this at the bolt-up in-process, at the transition region of buckling of engaging lug root, the muffler staple bolt very easily produces the deformation, and forms a "people" font structure. Therefore, the holding effect on the silencer assembly is greatly reduced, and the potential safety hazard that the silencer falls off exists.

Disclosure of Invention

The utility model discloses be exactly to the current silencer staple bolt hold the not good problem of effect of holding tightly to the silencer assembly, and provide a hold the better silencer staple bolt of effect tightly.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: the utility model provides a silencer staple bolt, is including having the circular staple bolt body of open-ended the parallel outside extension in both ends of staple bolt body opening part has left engaging lug and right engaging lug left side engaging lug with the root of right engaging lug is close to the one end of staple bolt body is equipped with the boss respectively, the boss is "L" shape, just all correspond on left engaging lug, right engaging lug and the boss and seted up the through-hole.

The utility model provides a silencer staple bolt is through the root of controlling two engaging lugs, the one end setting that is close to the clamp body is the boss of "L" shape, and control all correspond on two engaging lugs and the boss and seted up the through-hole, when carrying out the closed fastening through the bolt to silencer staple bolt body like this, the root of buckling of controlling two engaging lugs supports through the boss and leans on the silencer, thereby reduce or avoid the extrusion deformation of staple bolt body, with the effect of holding tightly that improves the staple bolt body, the potential safety hazard that the silencer drops has been eliminated.

Furthermore, a lining block with the same height as the upper part of the reinforcing block is arranged between the opposite surfaces of the left connecting lug and the right connecting lug. The position that is easy to deform below is guaranteed to have reasonable clearance to under the effect of reinforcing block, better fastening.

Furthermore, the lining block is fixedly connected to the left connecting lug or the right connecting lug. The silencer staple bolt is more convenient in the assembling process like this.

Further, left side engaging lug with the other end of right side engaging lug all outwards extends and forms one "L" shape installation department, the installation department is used for placing and connects the cushion, just two vertical position on the left and right sides of installation department with it has seted up the through-hole to connect to correspond on the cushion. When the hoop body of the silencer is closed and fastened, the silencer assembly is fastened, and the whole silencer assembly is hung and assembled through the connecting rubber mat by using bolts.

Has the advantages that:

the utility model provides a silencer staple bolt is better to holding effect tightly of silencer assembly, has eliminated the potential safety hazard that the silencer drops, avoids not holding the noise that produces because of the staple bolt simultaneously.

Detailed Description

In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1-4: the utility model provides a silencer staple bolt, including having open-ended circular staple bolt body 1 the parallel outside extension in both ends of 1 opening part of staple bolt body has left engaging lug 2 and right engaging lug 3 left engaging lug 2 with the root of right engaging lug 3 is close to the one end of staple bolt body 1 is equipped with boss 4 respectively, boss 4 is "L" shape, just all correspond on left engaging lug 2, right engaging lug 3 and the boss 4 and seted up the through-hole.

Wherein, a lining block 5 with the same height as the upper part of the reinforcing block 4 is arranged between the opposite surfaces of the left connecting lug 2 and the right connecting lug 3.

Wherein, the lining block 5 is fixedly connected on the left connecting lug 2 or the right connecting lug 3.

Wherein, the other end of left engaging lug 2 and right engaging lug 3 all outwards extends and forms one "L" shape installation department, and the installation department is used for placing and connects cushion 6, and corresponds on two vertical position of the left and right sides of installation department and the connection cushion 6 and has seted up the through-hole.

FIG. 5 is a schematic view of the hoop stress of the muffler, in the original deformation region, because a reinforcing block 4 is added on each of the left and right sides, and a lining block 5 equal in height to the upper part of the reinforcing block 4 is arranged between the left engaging lug 2 and the right engaging lug 3 in the opposite direction; thus, when the bolt 7 is fastened, the pressure F and the pressure F' on the two sides of the bolt 7 form a resultant force, a good holding effect can be formed on the silencer assembly 8, and meanwhile, the whole silencer assembly 8 is hung and assembled through the connecting rubber mat 6 by using the bolt 7.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the technical scope of the present invention, and the technical scope of the present invention is also considered to fall into the scope of the claims.
