Abstract
The utility model discloses a connecting device of an automobile exhaust pipe, which comprises a connecting piece and a fixing device, wherein the connecting piece comprises a cylindrical hollow straight tube part and a fixed part; the fixed part is a lug boss arranged on the outer wall of the hollow straight tube part; fixed surfaces are arranged on two sides of the lug boss, and the fixed surfaces are conical surfaces the diameters of which are gradually reduced to be the same with the diameter of the hollow straight tube part; and the connecting piece is fixedly connected with the automobile exhaust pipe through the fixing device. The utility model has the advantages of no need of asbestos pad, cost saving, good exhaust effect and convenient assembly.
Description
Technical field
The utility model relates to the connection set of a kind of connection set of pipe, particularly a kind of automobile exhaust pipe.
Background technique
At present, the connection end face of existing automobile exhaust pipe is the plane, in order to guarantee that sealing can sandwich asbestos packing between two junction surfaces of outlet pipe that needs connect, this Placement causes the automobile exhaust pipe of both sides, joint to misplace easily, and decentraction influences its exhaust effect, and, because the assembling of automobile exhaust pipe has directivity, this fit is not easy to distinguish assembly direction, and dress is wrong easily.
The model utility content
The purpose of this utility model is the problem that needs asbestos packing, the dislocation easily of when assembling, decentraction and assembly direction to make mistakes easily at the existing automobile exhaust pipe connection described in the background technique, and a kind of connection set of automobile exhaust pipe is provided.
The realization the technical solution of the utility model is as follows:
A kind of connection set of automobile exhaust pipe, it comprises link and fixing device, described link comprises columniform hollow straight-tube portion and fixed position, described fixed position is the projection that is arranged at the outer wall of hollow straight-tube portion, these projection both sides are stationary plane, this stationary plane is that diameter is reduced to and the identical conical surface of described hollow straight-tube portion diameter gradually, and described link connects the back by the fixing device connection that is fixed with automobile exhaust pipe.
Angle between the cross section of described stationary plane and hollow straight-tube portion is 10 °～30 °.
The length of the hollow straight tube in the left side of described projection is greater than the length of the hollow straight tube on protruding right side.
Described fixing device is a clip.
Described fixing device is a flange.
The beneficial effects of the utility model are because the connection set of this automobile exhaust pipe, in the middle of hollow straight tube, be provided with projection, the projection both sides are the oblique stationary plane of 10 °～30 ° angle, the connection end face of outlet pipe is arranged to oblique stationary plane equal angular with protruding both sides, the connection set of outlet pipe and this automobile exhaust pipe is connected the back to be fixed with clip or flange, good airproof performance, do not need to use asbestos packing, can save cost, and because protruding both sides are provided with hollow straight-tube portion, so between automobile exhaust pipe connection and the connected automobile exhaust pipe radial displacement can not take place, so can guarantee that device is concentric, exhaust effect is better, because the long length difference of the hollow straight-tube portion in protruding both sides, so that distinguish the connecting direction of automobile exhaust pipe, can not adorn mistake.
Description of drawings
Fig. 1 is the schematic representation of link of the present utility model;
Fig. 2 is the schematic representation of fixing device of the present utility model;
1 is link in the accompanying drawing, and 2 is hollow straight-tube portion, and 3 is projection, and 4 is stationary plane, and 5 is fixing device, and β is the angle between stationary plane and the hollow straight tube cross section.
Embodiment
Connection set with reference to a kind of automobile exhaust pipe shown in accompanying drawing 1 and the accompanying drawing 2, it comprises link and fixing device, described link comprises columniform hollow straight-tube portion and fixed position, described fixed position is the projection that is arranged at the outer wall of hollow straight-tube portion, these projection both sides are stationary plane, this stationary plane is that diameter is reduced to and the identical conical surface of described hollow straight-tube portion diameter gradually, and described link connects the back by the fixing device connection that is fixed with automobile exhaust pipe.Angle β between the cross section of described stationary plane and hollow straight-tube portion is 10 °～30 °, and in an embodiment, for guaranteeing its sealing effect, this angle is 20 °.The length of the hollow straight tube in the left side of described projection is greater than the length of the hollow straight tube on protruding right side.Described fixing device can be clip, also can be flange.
Because the connection set of this automobile exhaust pipe, in the middle of hollow straight tube, be provided with projection, the projection both sides are the stationary plane of 10 °～30 ° angle, the connection end face of outlet pipe is arranged to stationary plane equal angular with protruding both sides, the connection set of automobile exhaust pipe and this automobile exhaust pipe is connected the back to be fixed with clip or flange, good airproof performance, do not need to use asbestos packing, can save cost, and because protruding both sides are provided with hollow straight-tube portion, so between automobile exhaust pipe connection and the connected automobile exhaust pipe radial displacement can not take place, so can guarantee its concentricity, exhaust effect is better, because the length difference of the hollow straight-tube portion at the connection set two ends of this automobile exhaust pipe, so that distinguish the connecting direction of automobile exhaust pipe, can not adorn mistake.
