Description

[Detailed description of the invention] [Industrial application field] This invention relates to an oil level gauge for a cartridge oil tank of an oil combustor or the like.

[Conventional technology]

Cartridge oil tanks are oil tanks that must be sealed tightly, so an exposed type oil level gauge cannot be used, and since the position of the oil tank is reversed when in use and when refueling, the oil level display becomes confusing. type oil level gauges are becoming commonplace.

This transmission-type oil meter has the disadvantage that it cannot accurately display the remaining oil amount, so the applicant proposed Utility Model Application No. 61-96329 to develop an oil meter that can accurately display the amount of oil remaining during refueling and use. I was able to make a suggestion and install it on the cartridge oil tank.

[Problems that the idea should solve]

By the way, as mentioned above, small transparent cartridge oil tanks have become commonplace and are extremely inexpensive, so implementing the complicated oil gauge proposed by the applicant is almost cost-effective. It's becoming possible. In addition, in the embodiment of the proposed structure, the movable member is supported on a cantilever, so smooth operation cannot be expected unless it is made accurately, which also causes high costs.

[Means for solving problems]

In view of the above points, this invention enables parts to be constructed from inexpensive plastics, and by making assembly extremely simple, it is possible to significantly reduce costs. 1 is a cartridge oil tank, 2 is a through hole drilled in the side wall of the oil tank 1 at approximately the center, 3 is a float, 4 is an armrest, 5
is an oil level gauge body that rotatably holds the arm rod 4.
The oil level gauge body 5 is formed of a transparent body, and has two retaining plates 5'' protruding from a flat base 5'.
It is inserted into the oil tank 1 from above, and is sealed with a through hole 2 at the base 5' of the oil quantity gauge body 5. 11 is oil level gauge body 5
and the side wall of the oil tank 1.
12 is a push plate, 13 is a mounting screw, and the oil amount gauge body 5 is fixed to the oil tank 1.

The armrest 5 is made of an elastic material made of synthetic resin.
Moreover, the tip of the armrest 5 is divided into two parts. 8 is arm stick 5
9 is a locking hole provided in the retaining plate 5'' of the oil level gauge body 5;
The elastic force of the armrest 5 is used to fit the projection 8 into the locking hole 9, and the projection 8 becomes the center of rotation of the armrest 5.

6 is an indicator located between the two halves of the arm bar 4; 10 is a rotating shaft installed between the retaining plate 5'' of the oil level gauge body 5; A relief hole 14 is provided at each end of the arm rest 4 so that the arm rest 4 can rotate around the protrusion 8 even when the arm rest 4 is rotated. The indicator 6, which looks into the through hole 2, can be freely rotated between the two drive sections 7, and the display position changes depending on gravity during refueling and when in use. It's on.

The rotation shaft 10 is formed in an L shape, and one end passes through the retaining plate 5'' of the oil level gauge body 5 and the indicator 6, and serves as the center of rotation of the indicator 6, and the other end is the center of rotation of the indicator 6. It is engaged with the engaging portion 15 of the retaining plate 5'' of the oil level gauge body 5 to prevent it from coming off.

[Explanation of action]

The mechanism for driving the oil level indicator 6 is the same as the one proposed by the applicant, and consists of an armrest 4 with a float 3 attached.
When the display unit 6 rotates due to the oil level, one of the drive units 7 provided at two locations on the armrest 4 rotates the display unit 6 against gravity. Even if the relative angle between the arm rod 4 and the oil level gauge body 5 is constant, if the oil tank 1 is reversed, the indicator 6 will rotate due to gravity and lock with the other drive unit 7, Therefore, the position displayed from the through hole 2 is different, and the oil amount can be displayed appropriately at the time of refueling and use.

In this invention, the arm bar 4 is made of an elastic material made of synthetic resin, so the arm bar 4 whose tip is divided into two parts can be easily bent inward, and the protrusion 8 is connected to the locking hole of the oil level gauge body 5.
Can be fitted with. In addition, a space can be formed between the armrest 4 divided into two parts, and if the display 6 is positioned in this space and the L-shaped rotating shaft 10 is inserted, the display 6
can be attached to the oil level gauge body 5, and the indicator 6 can be freely rotated by gravity. Further, the other end of the rotating shaft 10 is hooked and locked onto the engaging portion 15 of the oil level gauge body 5 or the like.

[Explanation of effects]

As described above, this invention uses the elastic force of the synthetic resin to engage the arm stick 4 and the oil level gauge body 5, and since this engagement is performed at two places, the rotation of the arm stick 4 is very accurate. It has become.

On the other hand, since the tip of the armrest 4 is divided into two in order to perform this engagement at two places, the display 6 can be positioned between the two tips, and the rotation axis 10 of the display 6 is formed into an L-shape. Since the other end is locked to the oil level gauge body 5, it is easily prevented from coming off.

Therefore, it can be easily assembled by hand without using any tools, and the assembly cost has been greatly reduced. Also armrest 4
If other parts are also made of plastic, the mold cost for the parts during mass production will be negligible, approaching the cost of plastic material, and the overall unit price of the oil gauge will be even cheaper. For this reason, it is an extremely practical idea that can be implemented even in inexpensive models of oil combustors.
