Abstract
The utility model discloses an anti-splashing device of an fuel filling pipe of a motor vehicle fuel tank, comprising a fuel filling pipe arranged on the motor vehicle fuel tank, wherein the front end of the fuel filling pipe is provided with a fuel filling pipe inserting and fitting joint of a fuel filling gun, and the front end of the fuel filling pipe inserting and fitting joint of the fuel filling gun is provided with a fuel filling pipe mouth conduit of the fuel filling gun. As a fuel filling pipe inserting and fitting casing pipe and the fuel filling pipe mouth of the fuel filling gun in the device are fit, i.e. the external diameter of the fuel filling pipe mouth is bigger than the internal diameter of the filling pipe inserting and fitting casing pipe for 1-2mm, the fuel filling pipe is covered by the casing pipe. Fuel does not splash when colliding with the wall of the fuel filling pipe of the fuel tank under the pressure action when the fuel is filled, the fuel filling pipe of the fuel filling gun is guided by the conduit, and the action of an elastic body is convenient for inserting the fuel filling pipe mouth. The device has simple structure and is convenient to install.
Description
Technical field
The utility model belongs to the automotive oil tank parts, is specifically related to a kind of structure of motor vehicle oil tank fuel filler pipe.
Background technology
At present when being the fuel up of motor vehicle oil tank, all be that filler neck with oil gun is inserted in the motor vehicle oil tank fuel filler pipe, because the filler neck and the gap between the tank filler tube of oil gun are bigger, under the pressure effect of fuel oil when filling, the collision of tank filler tube tube wall, tend to occur the phenomenon that fuel oil spills, particularly when filling diesel oil, this phenomenon is more outstanding.Simultaneously, oil gas VOC (volatile organic matter) also can emit, and environment is polluted.
Summary of the invention
The purpose of this utility model is to provide a kind of motor vehicle oil tank fuel filler pipe to prevent spattering device outward, to address the above problem.
The technical solution of the utility model is: the anti-outer device that spatters of motor vehicle oil tank fuel filler pipe, it comprises the fuel filler pipe on the motor vehicle oil tank, the filler neck that the fuel filler pipe front end is provided with nozzle inserts the joint that cooperates, and the filler neck of nozzle inserts the filler neck conduit that cooperates the joint front end to be provided with nozzle.
Described joint comprises the elastic body that is provided with in the fuel filler pipe front end, and elastic body is provided with guide hole, and the fuel filler pipe mouth of pipe that is provided with nozzle in the guide hole inserts and cooperates sleeve pipe.
Described elastic body back segment is a frustum.
Described elastic body adopts rubber, and the fuel filler pipe mouth of pipe inserts and cooperates sleeve pipe to become whole with the vulcanization of rubber.
Because inserting, the fuel filler pipe mouth of pipe in this device cooperate sleeve pipe to match with the fuel filler pipe mouth of pipe of nozzle, the external diameter that is the fuel filler pipe mouth of pipe cooperates the internal diameter of sleeve pipe little 1～2 millimeter than inserting with the fuel filler pipe mouth of pipe, sleeve pipe encases the fuel filler pipe mouth of pipe, under the pressure effect of fuel oil when filling, outer spilling do not understood in the collision of tank filler tube tube wall, conduit is the fuel filler pipe realization guiding of nozzle simultaneously, and elastomeric effect, is convenient to the insertion of the fuel filler pipe mouth of pipe.This apparatus structure is simple, and is easy for installation.
Description of drawings
The anti-outer apparatus structure scheme drawing that spatters of Fig. 1 motor vehicle oil tank fuel filler pipe.
The specific embodiment
As shown in Figure 1, be provided with joint in the preceding end housing of tank filler tube 1, joint comprises the oil proof rubber elastic body 2 that is connected and fixed with the fuel filler pipe outer casing inner wall, oil proof rubber elastic body 2 leading portions are cylindrical, back segment is a taper type, oil proof rubber elastic body 2 is provided with guide hole 3, and fluidisation is connected with the fuel filler pipe mouth of pipe insertion cooperation sleeve pipe 4 of nozzle in the guide hole 3, and sleeve pipe 4 internal diameters are bigger 1～2 millimeter than the external diameter of the fuel filler pipe mouth of pipe.Sleeve pipe 4 front ends are provided with protection flange 6, and protection flange 6 is connected with oil proof rubber elastic body 2 end faces.The joint front end is provided with the filler neck conduit 5 of nozzle.
Claims (4)
1. a motor vehicle oil tank fuel filler pipe is prevented the outer device that spatters, it comprises the fuel filler pipe on the motor vehicle oil tank, it is characterized in that the fuel filler pipe front end is provided with the joint of the filler neck insertion cooperation of nozzle, the filler neck of nozzle inserts the filler neck conduit that cooperates the joint front end to be provided with nozzle.
2. the motor vehicle oil tank fuel filler pipe spatters device outside preventing according to claim 1, it is characterized in that described joint comprises the elastic body that is provided with in the fuel filler pipe front end, and elastic body is provided with guide hole, and the fuel filler pipe mouth of pipe that is provided with nozzle in the guide hole inserts the cooperation sleeve pipe.
3. the motor vehicle oil tank fuel filler pipe spatters device outside preventing according to claim 1, it is characterized in that the elastic body leading portion is a frustum.
4. spatter device outward as motor vehicle oil tank fuel filler pipe as described in the claim 2 is anti-, it is characterized in that the sleeve pipe front end is provided with the protection flange, the protection flange is connected with oil proof rubber elastic body end face.
