[Field of design]

The present invention relates to a fuel inlet cap of a vehicle, and more particularly to a fuel inlet cap opening and closing structure of the vehicle to open and close the cap easily and easily.

[Private Technology]

In general, the conventional fuel inlet cap has a male thread portion 52 formed under the head 51 of the cap 50, as shown in FIG. 4 (a) and (b), to open and close the screw in the fuel inlet 53. It is common to form a structure.

However, in the opening and closing method of opening and closing the cap by the screw type as described above, there is a lot of inconvenience in use by screwing or loosening when opening and closing the fuel inlet for fuel injection.

And if the cap is tightened too hard to be opened only by applying a large force, a person without power has a lot of difficulty in opening the cap.

Summary of the proposal

Therefore, the present invention has been devised to solve the above problems, and an object of the present invention is to provide a fuel inlet cap of a vehicle that can provide convenience in use by opening and closing the cap easily and easily.

In order to realize this, the present invention is formed by the upper body and the lower body is divided into a case where the coupling is made by interposing the packing in the middle;

A cam having a convex portion at both sides thereof, and having a connecting rod installed at an upper side of the central portion thereof, the cam being embedded in the case, and whose upper end portion penetrates the upper portion of the upper body to protrude upward;

It is provided to the fuel inlet cap of the vehicle comprising a locking member which is disposed on both sides of the cam through the through hole drilled in the lower body of the case and the locking member is locked in the locking groove provided in the fuel inlet.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention capable of realizing the above object in detail as follows.

EXAMPLE

1 is an exploded perspective view of a cap according to the present invention, 1 denotes a cap.

The cap 1 fuels the cap 1 while being unfolded from side to side by rotation of the cam 2 and the cam 3 installed inside the case 2 and the case 2 divided up and down. It comprises a locking member (4) for locking to the injection port (10).

In the case 2 is a sealing container formed by the upper body 20 and the lower body 21 is divided into the upper and lower parts through the packing 22 in the middle, the vehicle body 21 is a fuel inlet 10 It has an outer diameter that can be inserted into it.

The packing 22 is in close contact with the inner diameter of the fuel inlet 10 when the cap 1 is closed to maintain the sealed state.

The cam 3 settled into the case 2 has convex portions 30 and 31 on both sides thereof, and a connecting rod 33 is placed above the central portion thereof so that an upper end thereof penetrates the center of the upper body 20. The handle 34 is fixed to the end thereof.

In the above, the handle 34 is formed in a shape that is easy to rotate by the user gripping, when rotating the handle 34 of the cam 3 is interlocked.

And the locking member (4) which moves left and right by the head of the convex portion (30) 31 according to the rotation of the cam (3) is formed in a pair of left and right, the front end thereof is formed in a wedge shape so that the front end of the case As it enters and exits through the through holes 210 and 211 formed in the lower body 21 of (2), it is caught by the locking groove 11 provided in the fuel injection port 10.

And the locking member 4 is formed with a small diameter portion outside the middle portion, the elastic member 41 is held between the jaw 40 and the through hole 210, 211, the elastic member 41 is always It exhibits an elastic force for pushing the locking member 4 to the cam 3 side.

The cap 1 configured as described above closes the fuel inlet 10 in a state similar to that of FIG.

That is, in order to close the fuel inlet 10, the protrusions 30 and 31 of the cam 3 are locked by the locking member 4 while the cap 34 is inserted into the fuel inlet 10. ) And the locking member 4 is pushed outward by the lift of the convex portions 30 and 31 of the cam 3 and the tip thereof is inserted into the locking groove 11 formed in the fuel inlet 10. I get caught.

Accordingly, the cap 1 closes the fuel inlet 10 while the locked state is maintained in the state shown in FIG. 2.

At this time, the packing 22 is in close contact with the inner diameter portion of the fuel inlet 10 is of course the sealing is maintained.

Then, when opening the cap to inject fuel in the state in which the cap 1 is locked as described above, when the knob 34 is rotated 90 degrees, the convex portion 30 of the cam 3 which has pushed the locking member 4 to the left and right sides. Since the 31 releases the pushing force while the locking member 4 is moved into the case 2 by the elastic restoring force of the elastic member 41, the locking member 4 is released from the locking groove 11 to release the locking state. .

As described above, when the cap 1 is removed from the fuel inlet 10 while the locking is terminated, the fuel inlet 10 is completely opened to inject fuel.

As described above, according to the present invention, by rotating the handle with a small force, the locking or locking of the cap can be released, which is a useful design that can open and close the cap more easily and easily.
