JP2551588Y2 - Refilling structure of fuel filler lid - Google Patents

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a structure for fixing the oil supply lid of an oil tank used in an oil combustor with a sharp so as not to be lost.

[Prior art] Generally, when refueling an oil tank, the refueling lid is removed from the refueling port of the oil tank, and then refueling is performed. Is often the case. For this reason, there is a proposal in which the fuel filler cap is connected to the oil tank with a string or a sword to prevent the fuel filler cap from being lost. (Refer to Japanese Utility Model Publication No. 56-24827.) Also, in the case of using a flexible ball wedge that is excellent in design among strings and wedges, the spherical part at one end of this wedge is attached to the filler cap, while In some cases, the connecting body at the other end of the hook is fitted to the locking portion of the fixing plate, and the locking portion of the fixing plate is deformed by a tool in order to prevent the ball clip from falling off, so that a retaining structure is provided.

[Problem to be Solved by the Invention] As described above, in the structure in which the connection body of the ball squirrel is fitted to the locking portion of the fixing plate and the locking portion is deformed to prevent the connection body from coming off, A special tool for deforming the part is required, and the work of deforming makes the appearance unsightly and further requires extra work steps.

In the case of a structure in which one end of the ball clip is screwed to the fixing plate with a screw instead of the locking part of the fixing plate as a structure to make the appearance beautiful, a screw part for newly screwing is fixed. A step of welding to a plate is required, and there is a disadvantage that the manufacturing cost is increased.

[Means for Solving the Problems] The present invention proposes a new fixing structure to solve the above problems. That is, adjacent spherical portions are connected to each other by a connecting member 2a having a small diameter to form a ball ring 2, one end of the ball ring 2 is fixed to the oil supply port lid 1 of the oil tank, and the other end of the ball ring is In the fixing structure of the fuel filler cap which fits with the locking part 4 of the fixing plate 3 and holds the fuel filler cap 1 to the fixing plate 3, the locking part 4 of the fixing plate 3 includes the horizontal part 4a and the horizontal part 4a. With the hanging part 4b which continues downward from the end, it is formed into a substantially inverted L-shaped slit hole, and the horizontal gap A of the locking part 4 is about 1.5 to 2 times the diameter of the connecting body 2a, In addition, the hanging part gap B is set to be about 2.5 times the diameter of the connecting body 2a and smaller than the spherical part.

[Action] This invention, which has the structure described above, uses an oil tank 1 and a fuel filler lid 1
Are fixed to each other by a ball ring 2. The locking portion 4 of the fixing plate 3 of the oil tank 1 has a substantially inverted L-shape including a horizontal portion 4a and a hanging portion 4b continuous to an end of the horizontal portion 4a. Since the gap dimension A of the horizontal portion 4a is larger than the diameter of the connecting body 2a of the ball clip 2, the dimension can have a margin when inserted correctly into the locking portion 4, so that the insertion can be performed smoothly. , If it reaches the hanging part 4b through the horizontal part 4a, the ball waist 2 is always hanging down by gravity.
It moves to the lowermost end of 4b and is fitted.

Since the gap B of the hanging portion 4b is larger than that of the horizontal portion 4a, the connecting body 2a of the ball 2 is
After being properly fitted to the 4b, it can freely move in the hanging part 4b.

Further, the gap dimension A of the horizontal portion 4a is equal to the gap dimension B of the hanging portion 4b.
Because the connecting body 2a that moves the hanging part 4b is narrower than the horizontal part
Unless the direction of movement is changed at the connection portion with 4a, it is impossible to move to the horizontal portion 4a, and the ball fitting 2 that can be easily fitted does not come off during normal use in which the refueling port cover 1 moves. However, holding the base of the ball 2
, There is room in the gap dimension A of the horizontal portion 4a,
The ball 2 can be easily removed.

[Example] Hereinafter, the structure and operation will be described with reference to the drawings showing an example. Reference numeral 1 denotes an oil filler cap that is attached to and detached from an oil filler port provided on the upper surface of an oil tank, and 2 includes a spherical portion and a connecting body 2a connecting the spherical portion. The ball ring 2 has flexibility by connecting adjacent spherical portions with each other with a small diameter connecting body 2a, and one end of the ball ring 2 is fixed to the refueling port lid 1. .

Reference numeral 3 denotes a fixing plate formed on the main body of the oil tank or a frame attached to the oil tank, and 4 denotes a locking portion provided on the fixing plate 3.
The fixing plate 3 is formed by using an appropriate portion such as a main body of the oil tank or a frame attached to the oil tank, or is formed by fixing another member by means such as spot welding.

4a is a horizontal portion formed by slit-shaped cuts from the end of the fixed plate 3, 4b is a slit-shaped hanging portion continuously formed downward from the end of the horizontal portion 4a, and a horizontal portion 4a and a vertical portion 4b Are arranged in a substantially inverted L-shape to form the locking portion 4.

The gap A of the horizontal portion of the slit-shaped locking portion 4 is set to be 1.5 to 2 times the diameter of the connecting body 2a of the ball clip 2, and the gap B of the hanging portion following the horizontal portion 4a is The gap dimension B of the hanging portion 4b of the locking portion 4 is set to be about 2.5 times larger than the diameter of the linked body 2a of the grommet 2 so that the grommet 2 does not come off from the slit-shaped hanging portion 4b. It is set smaller than the spherical portion of the ball ring 2.

In order to fit the ball 2 into the locking portion 4 of the fixing plate 3,
First, the connecting body 2a of the ball wedge 2 is fitted to the horizontal portion 4a,
Since the gap A has a sufficient margin, the workability at the time of fitting the connector 2a is not impaired. Next, the connected body 2a of the ball squirrel 2 fits into the continuous hanging part 4b passing through the horizontal part 4a,
Is located at the lowermost end in the wide hanging portion 4b.

Then, the horizontal portion is set with respect to the gap size B of the wide hanging portion 4b.
Since the gap dimension A of 4a is narrow, even if the end of the ball clip 2 is pulled by the refueling lid 1 and moves in the hanging part 4b, the moving direction is different from the slit direction of the horizontal part 4a. It has become difficult to separate easily.

If the gap size A is slightly wider than the diameter of the connecting body 2a, it can be inserted. However, in practice, it is necessary to slide the inside of the horizontal portion 4a accurately, and it may be caught in the middle. 1.5 ~ in consideration of flesh by surface treatment such as
It is doubled.

In addition, the fact that the gap dimension B of the vertical portion 4b is set to about 2.5 times means that after the ball wedge 2 is fitted to the locking portion 4, the ball wedge 2 can move freely inside the locking portion 4 and is caught in the middle. Without falling, it always falls to the lowest point of the hanging part 4b.

[Effects of the Invention] The present invention has the above-described configuration and operation, and the ball wedge 2 can be attached only by fitting the connecting body 2a from the horizontal portion 4a of the locking portion 4 to the hanging portion 4b. Yes, it cannot be easily removed once it is stored in the hanging part 4b.

Further, since the gap dimension A of the horizontal portion 4a is set to 1.5 to 2 times as large as that of the connecting body 2a, the work of fitting the connecting body 2a can be easily performed, and there is no possibility of being caught during the fitting.

Further, since the gap B of the hanging portion 4b is made larger than the gap A of the horizontal portion 4a, the degree of freedom of the attached ball rim 2 is sufficiently ensured, and the removed fuel filler cap 1 is pulled. In the direction, the tip of the ball 2 can move freely in the hanging portion 4b.

Further, in order to fit and hold the ball rim 2 in the locking portion 4, it is not necessary to deform a part of the locking portion, so that the appearance can be kept beautiful.

On the other hand, since the locking portion 4 is formed in an inverted L-shape, once the ball set 2 is fitted into the locking portion 4, the connecting body 2a is carefully moved from the hanging portion 4b of the locking portion 4 along the horizontal portion 4a. It cannot be easily removed unless it is moved. At this time, the clearance A of the horizontal portion 4a is 1.5 to 2 times as large as that of the connecting body 2a, so that there is a sufficient margin and it can be easily removed.
