Abstract

The invention provides a turning plate type automobile fuel tank cap, wherein an inner cap is fixed in an outer cap; screw threads are positioned on the external side of the inner cap; orifices are provided on the middle of the outer cap top wall and the middle of the inner cap top wall; a flip cap is positioned at the orifices; the flip cap is hinged to the inner cap by a pin shaft; a spring is installed on the pin shaft; the two ends of the spring are respectively resisting against the flip cap and the inner cap; the orifice of the outer cap is sealed by the flip cap. After the flip cap provided by the invention is installed on a fuel filler of a fuel tank, the fuel filler can be sealed; when fueling, the flip cap is pushed inward by a fueling nozzle, the flip cap can be flipped inward, then, the fueling nozzle can enter into the fuel filler for fueling; after fueling is completed, the fueling nozzle is pulled out, the flip cap can be self-closed. Because the fuel tank cap does not need to be removed while fueling, usage abrasion of the fuel tank cap and the fuel filler can be slowed down; speedy and convenient fueling can be realized.

Description

The turnover plate type vehicle fuel tank cap

Technical field

The present invention relates to a kind of vehicle fuel tank cap.

Background technology

At present, generally the basic structure of the vehicle fuel tank cap of Cai Yonging is buckle-type, the shortcoming that the fuel lid of this buckle-type in use exists is: when 1, refueling, need fuel lid is taken off, adding needs behind the oil it is loaded onto again, and prolonged and repeatedly takes off, loads onto, cause the wearing and tearing of fuel lid and fuel filler pipe after, tolerance clearance is between the two strengthened, influence sealing effectiveness; When 2, refueling, fuel lid is taken off, loads onto, comparatively trouble influences not agility of gas filed.

Summary of the invention

The object of the present invention is to provide a kind of turnover plate type vehicle fuel tank cap, after this fuel lid was contained on the fuel filler pipe of automotive oil tank, under the state that does not take off, nozzle can directly pass it to refueling in the fuel tank.

For achieving the above object, the present invention adopts following scheme: the turnover plate type vehicle fuel tank cap, the enclosing cover internal fixation has inner cap, have screw thread on the outside of inner cap, the middle part of the middle part of lid top wall, interior lid top wall has a port outside, is provided with one at both passage port and renovates, renovate by bearing pin and inner cap hinged, spring is housed on bearing pin, the two ends of spring respectively with renovate, inner cap against, renovate will cover outward the port sealing.

By such scheme as seen, fuel lid provided by the invention can seal fuel filler pipe after being contained on the fuel filler pipe of fuel tank, when needs refuel, will inwardly renovate with nozzle and push, and renovates and can inwardly overturn, and nozzle then can enter fuel filler pipe and refuel; After oiling is finished, nozzle is extracted out, renovated and to close voluntarily.Owing to do not need this fuel lid is taken off when refueling, can slow down the use wearing and tearing of fuel lid and fuel filler pipe greatly.

The present invention can make the gas filed process simplify, and improves the gas filed agility, and it have long service life, to the characteristics of fuel filler pipe good sealing effect.

The specific embodiment

Further specify the present invention below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, Fig. 2

Turnover plate type vehicle fuel tank cap provided by the invention includes enclosing cover 1 and inner cap 2, inner cap 2 is fixed in the enclosing cover 1, has screw thread on the outside of inner cap, have port 1a, port 2a at the middle part of enclosing cover 1 roof, the middle part of inner cap 2 roofs, be provided with one at both passage port and renovate 3, renovate 3 hinged by bearing pin 4 and inner cap 2, spring 5 is housed on bearing pin 4, the two ends of spring 5 respectively with renovate 3, inner cap 2 against, under the effect of spring 5, renovate 3 the port 1a on the enclosing cover 1 sealed.

Be the leak tightness that cooperates between the fuel filler pipe that improves this fuel lid and fuel tank, be evenly equipped with the protruding 1b of some wedge shapes on the inboard of enclosing cover 1 sidewall, the tip of protruding 1b starts from the edge of enclosing cover 1 sidewall, is with seal ring 7 at the root of inner cap 2.

In addition, for strengthening the intensity of inner cap 2, be fixed with the gusset 2c more than two on the inwall of inner cap 2, gusset 2c and inner cap 2 are one.For being connected by the rope chain between the fuel filler pipe that makes this fuel lid and fuel tank, on the inwall of inner cap 2, be fixed with a support 2b, the bottom of support 2b has the through hole 2d that passes for the rope chain.

Referring to Fig. 1

For guarantee to renovate 3 with port 1a between the leak tightness that cooperates, renovate 3 middle part and have outstanding boss 3a, this boss 3a stretches among the port 1a on enclosing cover 1, at the root of boss 3a packing seal 6 is housed.
