The utility model has the following technical effects: the utility model relates to a sealing structure of a muffler, which comprises a base and an upper cover, wherein the outer side of the upper cover is connected with an outer sealing ring seat; according to the utility model, the sealing outer ring is inserted into the outer sealing ring seat, and the sealing ring is connected between the outer sealing ring seat and the sealing outer ring, so that the tightness between the base and the upper cover is greatly improved.
Drawings
The utility model is described in further detail below with reference to the attached drawings and detailed description:
FIG. 1 is a schematic view of a conventional muffler;
FIG. 2 is a schematic structural view of a sealing structure of a muffler according to the present utility model;
fig. 3 is an enlarged view of a portion a of fig. 2.
Detailed Description
The utility model is further described in detail below with reference to the accompanying drawings.
See fig. 1-3.
The sealing structure of the muffler comprises a base 1 and an upper cover 2 which is clamped above the base 1, wherein an outer sealing ring seat 3 is connected to the outer side of the upper cover 2, a sealing outer ring 4 is connected to the upper end of the base 1, the sealing outer ring 4 is inserted into the outer sealing ring seat 3, and a sealing ring 5 is connected between the outer sealing ring seat 3 and the sealing outer ring 4; specifically, the outer side of the sealing outer ring 4 is provided with an inclined surface 9, the inclined surface 9 inclines from bottom to top to the inner side of the sealing outer ring 4, and the sealing ring 5 is positioned between the inclined surface 9 and the outer sealing ring seat 3; according to the utility model, the outer side of the upper cover 2 is connected with the outer sealing ring seat 3, the upper end of the base 1 is connected with the sealing outer ring 4, and the sealing ring 5 is connected between the outer sealing ring seat 3 and the sealing outer ring 4, so that the tightness between the base 1 and the upper cover 2 is better.
Preferably, the inner side of the upper cover 2 is connected with an inner ring seat 6, a clamping groove 7 is formed in the inner ring seat 6, and the inner side of the base 1 is connected with a clamping block 8 corresponding to the clamping groove 7; the inner ring seat 6 is inserted into the base 1, the clamping block 8 is clamped in the clamping groove 7, the sealing outer ring 4 is positioned between the outer sealing ring seat 3 and the inner ring seat 6 (refer to fig. 2 and 3), the clamping block 8 is arranged on the inner side of the base 1, the inner ring seat 6 is inserted into the base 1, the clamping block 8 is clamped in the clamping groove 7, and compared with the existing connection mode (refer to fig. 1, a gap exists between the mounting clamping block 12 and the mounting clamping groove 11 after the mounting clamping block 12 is clamped in the mounting clamping groove 11, so that the sealing performance is poor), and the gap between the clamping block 8 and the clamping groove 7 is positioned in the base 1, so that the sealing performance of the connection between the upper cover 2 and the base 1 is not influenced, and therefore, the sealing performance of the utility model is relatively better.
