The top surface 1 of the appliance body is inwards recessed to form at least two cavity groups which are distributed in a central symmetry mode in the horizontal direction, each cavity group comprises a precatalyst cavity 21, a main catalyst cavity 22, a front silencer body cavity 23, a first air-entraining pipe type groove 231, a second air-entraining pipe type groove 232, a rear silencer body cavity 24 and an exhaust pipe type groove 241, and the cavity groups are respectively matched with a precatalyst 51, a main catalyst 52, a front silencer body 53, a first air-entraining pipe 531, a second air-entraining pipe 532, a rear silencer body 54 and an exhaust pipe 541 in an automobile exhaust system and used for accommodating the parts in the automobile exhaust system, namely the whole set of parts of the silencer assembly can be accommodated, and the transverse limiting effect is achieved. Because the appliance body accommodates the whole set of components of the muffler assembly, the assembly of the automobile exhaust system can be completed quickly after the automobile exhaust system reaches the destination, and the risk of part loss is greatly reduced.

As shown in fig. 8 to fig. 10, they are perspective views of the pre-catalyst, the main catalyst, the pre-muffler and the rear muffler respectively, wherein the pre-catalyst and the main catalyst have relatively compact structures, and the connection mechanism of the pre-muffler and the rear muffler is relatively loose, and is composed of a first bleed air pipe 531, a second bleed air pipe 532, a rear muffler body 54 and an exhaust pipe 541, which are connected in sequence.

As shown in fig. 1 to 6, they are a top perspective view, a bottom perspective view, an upper view, a front view, a left view and a lower view of the appliance body according to the embodiment of the present invention, respectively. The top surface 1 of the body is inwards sunken to form a supporting surface 2, the cavity group is formed on the supporting surface 2, and the rest top surface 1 of the body is in an annular square frame structure. The bottom surface 3 of the appliance body protrudes outwards to form a supporting boss 4, the contour of the supporting boss 4 is matched with that of the supporting surface 2, namely, the rest bottom surface 3 of the appliance body is also in an annular square frame structure. When two adjacent utensil bodies stack and place, the support boss 4 of upper utensil body imbeds to the holding surface 2 of lower floor's utensil body, and the body bottom surface 3 that upper utensil body is annular square frame structure supports to the body top surface 1 that lower floor's utensil body is annular square frame structure, realizes horizontal spacing between two adjacent utensil bodies, and the upper utensil body plays vertical spacing effect to the whole parts of silencer assembly that accept in the utensil body of lower floor simultaneously to firmly fix the silencer assembly in the die cavity group.

The support boss 4 is inwards sunken to form a plurality of reducing grooves 41, and reinforcing ribs 42 which are distributed in the X axial direction and the Y axial direction are formed between the adjacent reducing grooves 41 to enhance the structural strength of the appliance body.

The material reducing groove 41 and the reinforcing ribs 42 are inwards sunken to form an adaptation groove 44 which is adapted to the position and the shape of each part of the silencer assembly accommodated in the lower-layer appliance body, so that the parts of the silencer assembly are prevented from being damaged by extrusion.

The edge of the bottom surface 3 of the body is inwards recessed to form a plurality of grooves 43 which are symmetrically distributed left and right and symmetrically distributed front and back, when the plurality of appliance bodies are stacked and placed, an operator can stretch into the grooves 43, and the appliance bodies are easily lifted and carried. Symmetrically distributed's recess 43 can also play the effect of fixed bandage, avoids tying up the utility model discloses the bandage of commodity circulation utensil takes place the slippage.

In order to further improve the assembly efficiency of the automobile exhaust system, the front muffler body 53 may be connected to the rear muffler body 54 through the second bleed pipe 532, and then the muffler assembly may be accommodated in the cavity set of the appliance body. The embodiment of the utility model provides an in the utensil body can accomodate four sets of silencer assemblies, for improving packing space utilization, furthest reduces the horizontal size of utensil body, need make corresponding design improvement, promptly: the front muffler body cavity 23 is connected to the rear muffler body cavity 24 through a second bleed duct cavity 232 to form a muffler cavity for receiving the muffler assembly. The second bleed pipe type grooves 232 of two adjacent muffler cavities on the same side are crossed in opposite directions to accommodate two crossed muffler components, and the specific crossed part is an arc-shaped bulge at the middle section of the second bleed pipe 532, so that the crossed mode can reduce the horizontal space occupied by the two adjacent muffler components to the minimum under the condition of ensuring that the front muffler body 53 and the rear muffler body 54 are connected with each other.

In order to ensure the realization of the above structural design, the second bleed pipe shaped groove 232 of one of the muffler cavities is deeper than the second bleed pipe shaped groove 232 of the other muffler cavity, so as to ensure that the second bleed pipe shaped grooves 232 of the two muffler components do not exceed the supporting surface 2 of the appliance body upwards after being accommodated in a crossed manner.

In order to save the die sinking and production cost of the appliance body, the appliance body can adopt a split design and is formed by combining a plurality of appliances in a split way. In this embodiment, the tool body is formed by connecting a first tool split body 61, a second tool split body 62, a third tool split body 63, and a fourth tool split body 64, which are horizontally distributed, in a mortise and tenon joint structure. Namely, the inward side surface of any appliance split body is provided with a tenon projection 71 formed by protruding outwards and a mortise 72 formed by sinking inwards, and two adjacent appliance split bodies are connected through the tenon projection 71 and the mortise 72 which are matched with each other, so that stable connection is ensured. The four devices are formed integrally in a split mode so as to improve structural strength.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
