Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a level gauge, and more particularly to a level gauge used for detecting the liquid level of lubricating oil in a four-cycle engine or the like.

[0002]

2. Description of the Related Art In a four-cycle engine, as shown in FIG. 8, a predetermined amount of lubricating oil is stored in the lower part of an engine case A and is pumped up by an oil pump linked to the engine to prevent the engine from operating. The sliding surface is lubricated.

The engine case A has a hole B provided on the upper surface.
The level gauge C is inserted from. As shown in FIGS. 6 and 7, in the level gauge C, the upper end of the level rod E is attached to the handle D that also serves as a stopper, and the lower end of the level rod E is between the upper and lower limits of the liquid level of the lubricating oil. Is provided on the display unit F.

When checking the engine, the level gauge C
Can be pulled out and the liquid level can be known from the lubricating oil adhering to the display part F, the amount of lubricating oil can be known, the consumption level can be checked, and the contamination level of the lubricating oil adhering to the display part F can be checked. You can look up. This determines whether or not the lubricating oil needs to be replenished or replaced.

[0005] Further, there are some transmission cases, etc., in which transmission gears are housed, which are agitated and lubricated by the lubricating oil enclosed.

[0006]

However, there are various sizes of engine cases depending on the size of the engine, and there are also various sizes of mission cases and the like, depending on the type of mission. The liquid level of lubricating oil in the case is different. For this reason, in order to deal with this, the level gauge C, which has the length of the level rod E adjusted to the liquid level position of the lubricating oil, must be prepared as shown in FIGS. 6 and 7. Therefore, as the types of engine cases and the like increase, the types of level gauges C also increase, which requires more man-hours for production management and type management, and the types of replenishment level gauges C also increase, which increases storage costs and management personnel costs. There is a disadvantage.

Incidentally, such a problem does not occur only in the engine case of the four-cycle engine,
Of course, it can occur in the engine case of the two-cycle engine in which the lubricating oil of the same system as that of the four-cycle engine is stored in the mission chamber, or the case body of other various mechanical devices having the level gauge.

In view of the above point, the present invention can reduce the number of types by making one level gauge compatible with a plurality of case bodies having different liquid surface heights.
The purpose is to obtain a level gauge that can reduce the number of inventories, management costs, mass productivity, and cost.

[0009]

In order to achieve the above object, the present invention has the following constitution. That is,
The present invention is to be inserted from the outside of the case body to the inside in order to detect the amount of the liquid stored in the hollow case body, the level bar having a handle attached to the upper end, In a level gauge mainly consisting of a display unit for displaying the liquid level of a liquid, a plurality of display units which are arranged vertically on the level bar and are selected according to a predetermined liquid level, or It is a level gauge characterized in that it has a display portion which is separately provided so as to be slidable vertically with respect to a level bar and whose vertical position is adjusted according to a predetermined liquid level height.

[0010]

With a plurality of display units provided above and below the level bar, since each display unit can detect the liquid level, a plurality of case bodies having different predetermined liquid levels (for example, Engine case).
If you use the upper display and the lower display hits the bottom of the case, etc., and is in the way, bend the lower display upward or use pliers. Just cut it off.

Also, in the case where a display unit is provided slidably below the level bar, the vertical position of the display unit is adjusted according to a predetermined liquid level height, and further, for example, pliers at a predetermined position. Use by fixing with pressure contact. Accordingly, one level gauge can handle a plurality of liquid surface heights, that is, a plurality of case bodies (for example, engine cases), and the number of level gauges can be reduced.

[0012]

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3 show a first embodiment of the present invention. The level gauge of the first embodiment is, for example, an engine case of a motorcycle or the like (an example of a hollow case body).
An oil level gauge for detecting the amount of lubricating oil (an example of a liquid) stored in a level rod 1 having a handle 2 attached to the upper end thereof, and an oil liquid level provided on the level rod 1 vertically above and below. Mainly from two (one example of a plurality of) display units 3 selected according to the predetermined height of.

The level bar 1 is made of a mild steel round bar or a strip steel, but may be a synthetic resin bar. A handle 2 which also functions as a stopper is connected to the upper end (left end in the figure) of the level rod 1. The handle 2 is
It may be made of a light alloy or made of rubber or the like, and is connected to the level rod 1 by screwing or press fitting. In the lower part of the level bar 1, there are provided display parts 3 in which the upper and lower limits of the liquid level of the lubricating oil are shown by diagonal lines at two positions above and below. A folding line 4 is provided on the lower side of the upper display portion 3, and a bending piece 5 is provided on the lower end.

FIGS. 4 and 5 show a second embodiment of the present invention. The level gauge of the second embodiment has a display unit 3 which is provided so as to be slidable up and down with respect to the level rod 1 and whose vertical position is adjusted according to a predetermined height of the oil liquid surface. is there.

In this case, the display piece 6 provided with the display portion 3 is slidably connected to the lower portion of the level bar 1 having the handle 2 connected to the upper end thereof. At the lower end of the level bar 1 and the upper end of the display piece 6,
Bending pieces 7 are provided, each of which is a display piece 6 and a level bar 1.
It can be slid by holding it from the outside. The level bar 1 has a display piece 6
A registration mark 8 for aligning the position of the upper edge is engraved.

According to the first embodiment shown in FIGS. 1 to 3, the two upper and lower display portions 3 can detect two kinds of liquid surface heights and can be applied to two kinds of engine cases. If the lower end of the level bar 1 hits the bottom of the engine case when using the upper display unit 3, as shown in FIG. 3, bend it along the fold line 4 and use the pliers or the like to fold the bent piece 5. It may be bent or cut at the fold line 4.

In the case of the second embodiment shown in FIGS. 4 and 5, the display piece 6 is slid so that the upper edge is aligned with the alignment mark 8 and the bent piece 7 is clamped by pliers or the like. This makes it possible to deal with the detection of a plurality of liquid levels.

Therefore, according to the first and second embodiments, one level gauge can detect a plurality of liquid levels, that is, can correspond to a plurality of engine cases.
Therefore, the number of types of level gauges compatible with a large number of engine cases can be significantly reduced. As a result, the cost for mass production can be reduced and the management cost can be reduced.
