Abstract
The utility model relates to an exhaust pipe, in particular to an anti-falling-off exhaust pipe. The anti-falling-off exhaust pipe comprises an exhaust pipe body and a connection flange fixedly installed at one end of the exhaust pipe body, and an anti-falling-off structure is arranged at the other end of the exhaust pipe body. An anti-falling-off frustum type protruding structure is arranged on the connection portion of the metal exhaust pipe and a plastic pipe, the diameter of the frustum type protruding structure is gradually increased from the end outer edge to the interior, and when the plastic pipe is installed, the anti-falling-off frustum type protruding structure has the guide effect on the plastic pipe and brings convenience to installation of the plastic pipe. After installation, the plastic pipe and the exhaust pipe body are closely connected through a clamping hoop, the frustum type protruding structure has the good stopping effect on the clamping hoop and the plastic pipe and prevents the plastic pipe from sliding down, and the connection reliability is improved.
Description
Technical field
The utility model relates to a kind of outlet pipe, especially designs a kind of Drop-proof outlet pipe.
Background technique
Oil extraction/outlet pipe is many partly to be made up of metal tube part and plastic tube, plastic pipe sleeve is in the metal tube outside, both get up by clip connected, but existing oil extraction/outlet pipe mostly is the smooth exterior surface face, as shown in Figure 1, oil or temperature degree are higher in oil extraction/outlet pipe, under the bigger situation of the pressure of generation, make plastic tube landing from the metal tube easily, thereby influence the normal use of machine.In addition, existing metal tube outer surface does not have position structure, and the plastic tube position is too by the lining, and length may be not enough; Too outer join strength deficiency, easier landing, and adjust the plastic tube mounting point repeatedly and must influence efficiency of assembling.
The model utility content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of outlet pipe that prevents from moulding the pipe landing is provided.
The technological scheme that realizes the utility model purpose is: a kind of Drop-proof outlet pipe has outlet pipe body and the adpting flange that is fixedly mounted on outlet pipe one end; The described outlet pipe body the other end is provided with anti-drop structure.
Technique scheme, described anti-drop structure are and the integrated frustum type projection of outlet pipe.
Technique scheme, described frustum type projection external profile diameter increases inward gradually from end face.
Technique scheme is provided with positive stop lug boss apart from frustum type projection certain-length place on the described outlet pipe body.
Technique scheme, described positive stop lug boss are cylindrical, and with this body by integral forming of outlet pipe.
After adopting technique scheme, the utlity model has following positive effect:
(1) the utility model metal exhaust tube and plastic tube joint are provided with the frustum type protruding structure that prevents that plastic tube from coming off, frustum type projection port external profile diameter is little, increases gradually inward, when plastic tube is installed, can have leading role to it, make things convenient for the installation of plastic tube; After the installation, adopt clip that plastic tube and outlet pipe body are tightly linked together, the frustum type projection can both play good barrier effect to clip and plastic tube, prevents its landing, has increased connection reliability;
(2) positive stop lug boss that arranges on the outlet pipe body can play positioning action, can accurately and rapidly plastic pipe sleeve be connect in place; Positive stop lug boss and the integrated design of outlet pipe body, the defective of having avoided boss to adopt other Placements to come off, and can make production process simpler, enhance productivity.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is traditional exhaust pipe structure schematic representation;
Fig. 2 is the utility model structural representation;
Among the figure 1, the outlet pipe body; 2, adpting flange; 3, frustum type projection; 4, positive stop lug boss.
Embodiment
(embodiment 1)
See Fig. 2, the utlity model has outlet pipe body 1 and the adpting flange 2 that is fixedly mounted on outlet pipe body 1 one ends; Outlet pipe body 1 the other end is provided with anti-drop structure.
Preferably, anti-drop structure is and outlet pipe body 1 integrated frustum type projection 3, frustum type projection 3 external profile diameters increase inward gradually from end face, namely can when being installed, play plastic tube leading role, the convenient installation, the step that the afterbody of frustum type projection 3 and outlet pipe body 1 form can play barrier effect to plastic tube again, thereby prevents that effectively plastic tube from gliding.
Preferably, be provided with cylindrical positive stop lug boss 4 apart from frustum type projection 3 certain-length places on the outlet pipe body 1, positive stop lug boss 4 outlet pipe bodies 1 are one-body molded, and position-limiting action is played in the installation of plastic tube, can quickly and accurately plastic tube be installed to suitable position, thereby improve installation efficiency.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
