Summary of the invention
In order to address the above problem, the purpose of the utility model is to provide a kind of reasonable in design, the simple and practical and general fuel tank cap that is used for motor vehicle fuel case pressure test being convenient to operate.
In order to achieve the above object, the general fuel tank cap that is used for motor vehicle fuel case pressure test that the utility model provides comprises hinge-rod, stretch, hinge, big sealing gasket, pressure cap, little sealing gasket and nut; Wherein the bottom of the middle part of hinge-rod and stretch is formed with a slotted hole respectively, and is formed with external thread on the upper end outer peripheral face of stretch; Hinge interconnects hinge-rod and stretch with the mode that runs through above-mentioned two slotted holes; Big sealing gasket is arranged on the outside of fuel tank top tank mouth in the form of a ring; Pressure cap is to be made up of dome and edge, lower end one, and wherein the end face of dome middle part is formed with a stretch through hole, be formed with an air admission hole on the sidewall simultaneously, and the bottom surface at edge, lower end is placed on the surface of big sealing gasket; Little sealing gasket is arranged on the external margin place of stretch through hole on the pressure cap also ringwise; Nut then extends to the outside stretch upper end of pressure cap behind the stretch through hole and interconnects with the mode of threaded engagement with running through internally.
The length of described hinge-rod is greater than the diameter of reservoir port.
The internal diameter of described big sealing gasket is less than the internal diameter of reservoir port, and external diameter is then greater than the external diameter of reservoir port.
Described stretch upper end on it ultimate range between slotted hole greater than the bee-line between pressure cap end face to the inner wall of oil tank.
The internal diameter of described little sealing gasket equals the external diameter of stretch upper end.
The general fuel tank cap that is used for motor vehicle fuel case pressure test that the utility model provides can utilize regulate hinge on stretch in the slotted hole method of position adapt to the motor vehicle fuel case of different size; So not only versatility is good; Therefore can reduce production costs, and easy to operate.In addition, this general fuel tank cap also has reasonable in design, advantage such as simple and practical.
Description of drawings
The general fuel tank cap structural representation that is used for motor vehicle fuel case pressure test that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the general fuel tank cap that is used for motor vehicle fuel case pressure test that the utility model provides is elaborated.
As shown in Figure 1, the general fuel tank cap that is used for motor vehicle fuel case pressure test that the utility model provides comprises hinge-rod 1, stretch 2, hinge 3, big sealing gasket 4, pressure cap 5, little sealing gasket 6 and nut 7; Wherein the bottom of the middle part of hinge-rod 1 and stretch 2 is formed with a slotted hole respectively, and is formed with external thread on the upper end outer peripheral face of stretch 2; Hinge 3 interconnects hinge-rod 1 and stretch 2 with the mode that runs through above-mentioned two slotted holes; Big sealing gasket 4 is arranged on the outside of fuel tank 8 top tank mouths 9 in the form of a ring; Pressure cap 5 is to be made up of dome 10 and edge, lower end 11 one, and wherein the end face of dome 10 middle part is formed with a stretch through hole 12, be formed with an air admission hole 13 on the sidewall simultaneously, and the bottom surface at edge, lower end 11 is placed on the surface of big sealing gasket 4; Little sealing gasket 6 is arranged on the external margin place of stretch through hole 12 on the pressure cap 5 also ringwise; 7 on nut extends to outside stretch 2 upper ends of pressure cap 5 behind the stretch through hole 12 and interconnects with the mode of threaded engagement with running through internally.
The length of described hinge-rod 1 is greater than the diameter of reservoir port 9.
The internal diameter of described big sealing gasket 4 is less than the internal diameter of reservoir port 9, and external diameter is then greater than the external diameter of reservoir port 9.
