Abstract

The utility model discloses a tail pipe connected with an exhaust pipe, which is applied to an automobile exhaust system. A plurality of protrusions are uniformly distributed at the junction of the inner wall of the tail pipe and the outer wall of the exhaust pipe, the tail pipe is in interference fit with the exhaust pipe, and the protrusions are elastic. The utility model is convenient for dismounting and replacement and not liable to rust, and has a simplified installation process.

Description

A kind of tail pipe that is connected with outlet pipe

Technical field

The utility model is applied to automobile exhaust system, is specifically related to a kind of tail pipe that is used to connect the with groove of outlet pipe.

Background technique

Existing automobile exhaust system tail end outlet pipe mostly is equipped with the tail pipe that is used to decorate, though there is multiple Placement between tail pipe and the outlet pipe, defective is separately arranged also.

First kind welding type, as shown in Figure 1, promptly tail pipe 11 adopts welding with outlet pipe 12, but after the welding, has shortcomings such as dismounting and change inconvenience, welding part 13 easily get rusty.

Second class is detachable, and as Fig. 2, shown in Figure 3, tail pipe 21 adopts the tight mounting type of locking of clip with outlet pipe 22, and tail pipe 21 is fastened on the outlet pipe 22, and the groove 23 on the tail pipe 21 is linear, as shown in Figure 3.This Placement has dismounting, it is convenient to change, connection part advantage such as be difficult for getting rusty, but get loose easily, not too firm with respect to welding type.

The model utility content

The purpose of this utility model provides a kind of tail pipe that is connected with outlet pipe, can well solve dismounting and change inconvenience in the prior art, easily gets rusty problems such as installation steps complexity.

The purpose of this utility model is to be achieved through the following technical solutions:

The joining place of inner wall of liner and exhaust tube wall is the some projectioies of distribution evenly, tail pipe and outlet pipe interference fit, and projection has elasticity.

The utility model dismounting and change is convenient, is difficult for getting rusty, and installation steps are simple.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is a welding type device schematic representation in the prior art;

Fig. 2, Fig. 3 are disassembly-type device schematic representation in the prior art;

Fig. 4 is the generalized section of the described a kind of tail pipe that is connected with outlet pipe of the utility model embodiment;

Among the figure: 41, projection; 42, tail pipe; 43, outlet pipe.

Embodiment

In conjunction with the embodiments the utility model is described further.

A kind of tail pipe that is connected with outlet pipe of the utility model, as shown in Figure 4, the joining place of tail pipe 42 inwalls and outlet pipe 43 outer walls, it is some protruding 41 evenly to distribute, and projection 1 has elasticity, makes tail pipe 42 be connected formation interference fit afterwards with outlet pipe 43,

Preferably, tail pipe 42 inwalls have the size interference 1.6-1.0mm of 4 equally distributed protruding 41, protruding 41 circumferential sizes that form than outlet pipe 43, during installation, can adopt cylinder to promote tail pipe 42, make 4 projectioies of tail pipe 42 produce deformation, tightly wrap outlet pipe 43.

To sum up, the utility model makes the installation of tail pipe transit to semi-automatic the installation from simple manual operation, not only saves human cost greatly, and the conformity of installation, aesthetic property, versatility, Economy, practicability all obtain lifting by a relatively large margin.

Claims

1. a tail pipe that is connected with outlet pipe is characterized in that, the joining place of described inner wall of liner and described exhaust tube wall is the some projectioies of distribution evenly, described tail pipe and described outlet pipe interference fit, and described projection has elasticity.
