Specific embodiment

As shown in Fig. 1~2, a kind of automobile front lifting lug assembly, including Stainless Steel Shell 1, rubber block 2 and screw 3；Stainless steel The inside of Stainless Steel Shell 1 is arranged in the both ends open of shell 1, rubber block 2, and it is logical that the side of Stainless Steel Shell 1 offers first Hole 11, the end of thread of screw 3 pass through first through hole 11 from inside to outside and reach the outside of Stainless Steel Shell 1, accordingly, rubber The side of block 2 offers counterbore 26, and the head of screw 3 is embedded in counterbore 26；First is offered on one side end face of rubber block 2 Heavy chamber 21 has been outwardly formed first boss 22 on the bottom surface of first heavy chamber 21；Second is offered on another side end face of rubber block 2 Heavy chamber 24 has been outwardly formed second boss 25, the end face outside and second boss of first boss 22 on the bottom surface of second heavy chamber 24 Through hole 23 is offered between 25 end face outside；The both sides of the face edge of rubber block 2 has been outwardly formed an annular convex rib 27。

In use, the end of thread of screw 3 is screwed into the corresponding position on automobile exhaust system, in automobile exhaust system Mating bolt insertion be mounted in through hole 23, first boss 22 and second boss 25 are respectively as stress surface and automobile exhaust System is connected with each other, and so far completes the fixation of front lifting lug assembly；If first boss 22 and second boss 25 are squeezed by external force When, first boss 22 and second boss 25 can use the soft materials of rubber block 2 respectively in the first heavy chamber 21 and the second heavy chamber Compression or press-bending deformation in 24, play good buffering effect, and the first heavy chamber 21 and the second heavy chamber 24 are the first heavy chamber 21 Space is provided with compressing in the second heavy chamber 24 or bending deformation；Stainless Steel Shell 1 can be in the severe ring of automobile exhaust system It prevents from getting rusty or rotting in border, service life is longer；The annular convex rib 27 of two sides can prevent the both sides of the face of Stainless Steel Shell 1 straight It connects and is contacted with outside appurtenances, play good protective action.

Automobile exhaust system mainly discharges exhaust gas caused by engine operation, while subtracts the exhaust emission of discharge Small, noise reduces；Automobile exhaust system is generally by exhaust manifold, exhaust pipe, catalyst, exhaust gas temperature sensor, automobile The composition such as silencer and tailpipe, the front lifting lug assembly of automobile exhaust system are to be installed in the front side of automobile exhaust system to be used to Play the component of fixed suspension；Existing automobile front lifting lug is made of single rigid, when being squeezed by external force without Method flexible deformation can only generate rigid deformation, finally be broken because reaching fatigue strength, and then cause automobile exhaust system de- It falls；In addition, existing automobile front lifting lug is difficult to weaken the vibration generated by automobile exhaust system while playing the role of suspension, Falling off for automobile exhaust system is further speeded up；The utility model uses assembly structure, and the setting of Stainless Steel Shell 1 increases Outboard strength, effective protection rubber block 2, and rubber block 2 can using the plastic deformation of itself come when offsetting external force to even The influence of firmness is connect, so as to prolonged effectively suspension automobile exhaust system, extends service life；In addition, rubber block 2 The vibration generated by automobile exhaust system can substantially be weakened, there is effectiveness in vibration suppression, further improve the stability of suspension.

Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to It is so possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is replaced on an equal basis It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution Spirit and scope.
