In order to solve the above problems, the technical solution of the utility model is: a kind of fuel filler pipe assembly of manned vehicle, comprise fuel filler pipe, also be provided with guide piece in the described fuel filler pipe, comprise a straight pipe, circumferencial direction compartment of terrain along described straight pipe upper inner wall is provided with a plurality of gun barrel limiting stoppers, and described gun barrel limiting stopper comprises that for the fixing coupling end of straight pipe inwall, the opposite end of described a plurality of gun barrel limiting stopper coupling ends has surrounded for gun barrel guide space that penetrate and coaxial with straight pipe.
Preferably, the internal diameter on described guide space top increases gradually.
Preferably, the outer wall of described straight pipe termination radially is provided with the flange of a circle and fuel filler pipe groove fit.
Preferably, the circumferencial direction compartment of terrain along described straight pipe outer wall is distributed with a plurality of and the axial boss fuel filler pipe groove fit.
Preferably, also be provided with the longitudinal cross-section and be circular-arc bend pipe, and the connection pipe that is communicated with bend pipe and straight pipe.
Preferably, the internal diameter of described connection pipe reduces gradually from coupling end to the coupling end with bend pipe of itself and straight pipe.
Preferably, the inwall of described connection pipe is provided with the annular space consistent with straight pipe.
Preferably, the pipe shaft of described straight pipe is provided with a plurality of deflation holes.
Fuel filler pipe assembly of the present utility model, it is provided with guide piece simple in structure, and when rifle was inserted in oiling, this guide piece can limit the position of plugging in rifle, can avoid the early jump rifle that causes because of misoperation and the problem of regurgitating; This guide piece has increased the straight end oiling length of fuel filler pipe simultaneously, thereby improved the flowing space of fluid in the refueling process, postponed the collision of fluid and fuel filler pipe inwall, reduced the possibility of fuel oil regurgitate, the design of bend pipe has reduced the application force of the mobile break-in impact of fluid tube wall effectively, further reduced the possibility of fuel oil regurgitate, early jump rifle and the problem of regurgitating when effectively having avoided refueling.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.
Referring to figs. 2 to Fig. 5, the fuel filler pipe assembly of a kind of manned vehicle of the present utility model, comprise fuel filler pipe 9, at described fuel filler pipe 9 guide piece 1 is arranged fixedly, described guide piece 1 comprises a straight pipe 10 that supplies gun barrel 81 to penetrate, circumferencial direction compartment of terrain along described straight pipe 10 upper inner wall is provided with a plurality of gun barrel limiting stoppers 4, and preferably these a plurality of gun barrel limiting stoppers 4 are arranged on the circumferencial direction of straight pipe 10 inwalls equidistantly.With reference to figure 3, described gun barrel limiting stopper 4 comprises for the fixing coupling end 41 of straight pipe 10 inwalls, and the opposite end 42 of described a plurality of gun barrel limiting stopper 4 coupling ends has surrounded the guide space that penetrate and coaxial with straight pipe 10 for gun barrel 81.When refueling work, the gun barrel 81 of nozzle 8 is penetrated in the straight pipe 10 along this guide space, limited the position of hanging arms of nozzle 8 effectively, make the oil outlet of gun barrel 81 can not touch the inwall of straight pipe, more can not touch the inwall of fuel filler pipe, solve the problem of regurgitating when refueling.This straight pipe 10 has increased the actual straight end oiling length of fuel filler pipe simultaneously, thereby has improved the flowing space of fluid in the refueling process, has postponed the collision of fluid and fuel filler pipe inwall, has reduced the possibility of fuel oil regurgitate.
Self structure in view of nozzle in the prior art 8, the coupling end of gun barrel 81 and nozzle 8 bodies is crooked structure, so, the internal diameter on described guide space top is increased gradually, make the opening of this annular space be open structure, with reference to figure 3, the width of gun barrel limiting stopper 4 terminations reduces from bottom to up gradually, makes the termination of this gun barrel limiting stopper 4 be wedge shape.When gun barrel 81 puts in straight pipe 10 fully, make the opening of its bent position and this annular space match.
In the utility model, the fixed form of guide piece 1 and fuel filler pipe 9 can adopt structure well-known to those skilled in the art, and preferably, the outer wall in described straight pipe 10 terminations radially is provided with a circle flange 5.The inwall of this flange 5 and fuel filler pipe 9 adopts the mode of groove fit, the effectively axial motion of restricted guidance device.More preferably, the circumferencial direction compartment of terrain along described straight pipe 10 outer walls is distributed with a plurality of axial boss 3.3 axial earthen platforms 3 for example are set equidistantly, and cooperate with fuel filler pipe 9 inboard wall grooves, can prevent that this guide piece 1 from rotating along fuel filler pipe 9.
Fuel filler pipe assembly of the present utility model can also be done following improvement: also is provided with the longitudinal cross-section and is circular-arc bend pipe 11, and the connection pipe 12 that is communicated with bend pipe 11 and straight pipe 10.Afterbody at this straight pipe 10 arranges a bend pipe 11, in refueling process, can effectively guide fluid to flow smoothly, has reduced in the refueling process fluid to the impact of tube wall, thereby has further avoided the generation of regurgitating when refueling.
Fuel filler pipe assembly of the present utility model, it is provided with guide piece simple in structure, and when rifle was inserted in oiling, this guide piece can limit the position of plugging in rifle, can avoid the early jump rifle that causes because of misoperation and the problem of regurgitating; This guide piece has increased the straight end oiling length of fuel filler pipe simultaneously, thereby has improved the flowing space of fluid in the refueling process, has postponed the collision of fluid and fuel filler pipe inwall, has reduced the possibility of fuel oil regurgitate; The design of bend pipe has reduced the fluid break-in of flowing effectively and has impacted the application force of tube wall, has further reduced the possibility of fuel oil regurgitate, early jump rifle and the problem of regurgitating when effectively having avoided refueling.
The utility model is by preferred embodiment having carried out detailed explanation.Yet, by to the studying carefully of preamble, to the variation of each embodiment with to increase also be that one of ordinary skill in the art institute is apparent.Being intended that all these variations and increasing of applicant all dropped in the scope that the utility model claim protects.
