The specific embodiment
Cooperation is referring to shown in Fig. 1, Fig. 2, and vehicle fuel pipe described in the utility model, comprises: sebific duct 1, and be configured in sebific duct 1 and tighten cover 2, fast joint 3 and adaptor union 4, being axially equipped with opening and can making opening be interconnected of these parts with one end after assembling.Shown in each figure, be only wherein one end of sebific duct 1, and can be equipped with similarly described cover 2, fast joint 3 and the adaptor union 4 of tightening at the other end of sebific duct 1, or need also these parts not to be set according to application.
Wherein, described in tighten the end that cover 2 is set in sebific duct 1, the rear end of described fast joint 3 (left end of corresponding diagram 2) tightens in cover 2 described in being inserted into, and relies on the compression distortion that tightens cover 2, extruding sebific duct 1, makes fast joint 3 closely be connected with sebific duct 1.
The front end of described adaptor union 4 (right-hand member of corresponding diagram 2) can insert for client-side interface when application, realizes adaptor union 4 and is connected with the direct of client-side interface.Different described client-side interfaces can be respectively the corresponding interface of high-pressure oil pump, common rail pipe or metal straight pipe configuration.
When the rear end of described adaptor union 4 is inserted in the front end of described fast joint 3, the Clip Reed 5 arranging in described fast joint 3 front ends passes through radial dilatation, can realize self-locking to adaptor union 4 and the client-side interface inserting, to stop it to be extracted mistakenly when not needing.
Further coordinate referring to shown in Fig. 2, Fig. 3, Fig. 4 a and Fig. 4 b, the rear end of described adaptor union 4 can move forward and backward in the distance L of described fast joint 3 front end inner settings.The initial condition of adaptor union 4 when inserting be shown in shown in Fig. 4 a, and its rear end touches described Clip Reed 5, and the client-side interface now inserting in adaptor union 4 with direction shown in arrow 7 can carry out locking position by Clip Reed 5.
When needs are extracted client-side interface as shown in Figure 4 b, press the driving surface of described adaptor union 4 front ends, make adaptor union 4 miles of relative movement L backward in described fast joint 3, and push card reed 5 makes it compressive deformation radially occurs, now client-side interface can be exited.In the process of plug client-side interface, fast joint 3 links together with sebific duct 1 all the time by tightening cover.
In a concrete example, described sebific duct 1 is quality of rubber materials; Described adaptor union 4 is plastic materials; Described tighten cover 2 and fast joint 3 is metal materials, and can select in actual applications other material to make corresponding parts.
The concrete fitting process of above-mentioned vehicle fuel pipe is, adaptor union 4 is pressed fit into fast joint 3, by Clip Reed 5 radial dilatation, stops it to deviate from; Sebific duct 1 with tighten cover hand assembly; Machine press-fits fast joint 3 to sebific duct 1 endoporus; Press locking.
Can adjust the length of sebific duct 1 or walk to be always applicable to different customer requirements.During assembling, client-side interface is directly inserted in adaptor union 4.When needs take out client-side interface, the direction of inserting with client-side interface is pressed adaptor union 4, makes radially compressive deformation of Clip Reed 5, extracts client-side interface.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.Those skilled in the art, read after foregoing, for multiple modification of the present utility model with to substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
