Abstract
The utility model relates to a connecting device of an automobile exhaust pipe. The connecting device comprises an elbow and a straight pipe, wherein connecting ends are arranged at one ends of the elbow and the straight pipe; the connecting heads of the elbow and the straight pipe are connected with metal hoses; and the connecting heads are provided with guide ends, inserting ends and locating sections. When the connecting device of the automobile exhaust pipe provided by the utility model is in use, the inserting ends are very easily inserted into the metal hoses without damaging the inner walls of the metal hoses in the inserting process because the guide ends are conical surfaces; and the locating sections can be used for determining the inserting lengths of the inserting ends in the metal hoses, so that the straight pipe and the elbow can be well connected so as to ensure product quality of the automobile exhaust pipe. The connecting device of the automobile exhaust pipe provided by the utility model has the advantages of simple structure, reasonable layout, low making cost and the like.
Description
Technical field
The utility model relates to the auto parts machinery technical field, particularly a kind of connection set of automobile exhaust pipe.
Background technique
At present; Being connected of the metallic hose of existing automobile exhaust pipe and bend pipe is directly bend pipe to be inserted in the metallic hose, and this Placement is not sure of bend pipe on the one hand and is inserted into the length in the metallic hose, on the other hand because the front end of bend pipe is a straight tube; And directly be inserted in the metallic hose; Because function of friction is easy to the inwall of metallic hose is damaged, influence the product matter quality of automobile exhaust pipe.Gu how to guarantee the exhaust effect of automobile exhaust pipe, simplicity of design problem such as outlet pipe Placement has easily become the focus of research in the industry.
The model utility content
The purpose of the utility model is defective and the deficiency to existing technology, and a kind of connection set of automobile exhaust pipe simple in structure, reasonable in design, easy to use is provided.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:
The connection set of the described a kind of automobile exhaust pipe of the utility model; Comprise bend pipe and straight tube; Said bend pipe and said straight tube one end all are provided with connecting head, and the connecting head of said bend pipe and straight tube is connected to metallic hose, and said connecting head is provided with guide end, insertion end and positioning section.
Further, said guide end is coniform, and the cone angle of said guide end is 15 °～25 °, and the length of said guide end is 1～3mm.
Further, the length of said insertion end is 15～30mm.
Further, the inwall of said positioning section is convex ring shape.
Further, said metallic hose two ends are provided with the thick section, and the length of said thick section is identical with insertion end.
After adopting said structure; The utility model beneficial effect is: the connection set of the described a kind of automobile exhaust pipe of the utility model; Comprise bend pipe and straight tube; Said bend pipe and said straight tube one end all are provided with connecting head, and the connecting head of said bend pipe and straight tube is connected to metallic hose, and said connecting head is provided with guide end, insertion end and positioning section.When using the utility model; Because of guide end is the conical surface; So insertion end is inserted metallic hose at an easy rate, and can not damage the metallic hose inwall during insertion, positioning section can be used for confirming that insertion end is inserted into the inner length of metallic hose; So that make straight tube can reach good the connection with metallic hose with bend pipe, thus the quality of product of assurance automobile exhaust pipe.The utlity model has simple in structurely, be provided with rationally, advantage such as fabricating cost is low.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1; The connection set of the described a kind of automobile exhaust pipe of the utility model; Comprise bend pipe 1 and straight tube 3; Said bend pipe 1 all is provided with connecting head 4 with said straight tube 3 one ends, and the connecting head 4 of said bend pipe and straight tube is connected to metallic hose 2, and said connecting head 4 is provided with guide end 41, insertion end 42 and positioning section 43.
Said guide end 41 is coniform, and the cone angle of said guide end 41 is 15 °～25 °, its objective is when making insertion end 42 be inserted into metallic hose 2, and the port of insertion end 42 can not cause damage to metallic hose 2 inwalls.
The length of guide end 41 is too short can to influence the degree of difficulty that insertion end 42 is inserted metallic hose 2, so the optimum length of guide end 41 is 1～3mm.
The inwall of said positioning section 43 is convex ring shape, and its purpose is to confirm the length of insertion end 42 insertion metallic hoses 2 inside.
In order to guarantee that bend pipe 1 can reach the good effect that is connected with straight tube 3 and metallic hose 2, so the optimum length of insertion end 42 is 15～30mm.
Said metallic hose 2 two ends are provided with thick section 21, and the length of said thick section 21 is identical with insertion end 42, and its purpose is to increase metallic hose 2 abrasion resistances, prolong the working life of metallic hose 2.
When connecting outlet pipe, both can make straight tube realize quick and precisely being connected, and also can improve the working life of metallic hose, thereby guarantee the quality of product of automobile exhaust pipe with bend pipe and metallic hose with the utility model.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
