Description

[Detailed description of the invention] The present invention relates to a vehicle-mounted inclinometer, and is characterized in that air bubbles generated in the liquid filled between the outer container and the inner sphere are prevented from coming out in front of the inclinometer. In the past, in order to hide these air bubbles from view, an air reservoir was purposely provided in the outer container, which resulted in a large bulk and a complicated structure.

The present invention has been devised in view of these points, and its contents will be explained below based on the illustrated embodiments.

Reference numeral 1 denotes a spherical container which houses an inner sphere 2 and is filled with a liquid 3 such as oil.

Reference numeral 4 denotes a bubble hiding portion which is a step-shaped recess formed on the back surface including the top of the inner sphere 2.

Gases such as air mixed into the spherical container 1 during the manufacturing process of the inclinometer can be removed by placing the inclinometer horizontally.
Due to the difference in specific gravity with the liquid 3, the bubbles gather at the top, reach the bubble concealing portion 4 which is a larger gap, and are stored as a single bubble 5.

7 is the front panel, and θ is the visible range.

Reference numeral 8 is a weight which is installed in the hollow chamber 9 of the inner sphere 2. The liquid 3 described above has an inner sphere 2 containing a weight 8.
It is given the same weight as.

The center of buoyancy and the center of gravity of the inner sphere 2 are aligned on a vertical line, and the center of gravity is always located downward relative to the center of buoyancy.

10 is a groove provided in the inner sphere 2 into which a guide pin 11 protruding from the spherical container 1 is loosely fitted;
In the engagement range between the groove part 10 and the guide pin 11, the bubble concealing part 4 is prevented from appearing in the visible range θ.

12 is a mounting member.

Next, the operation of the present invention having the above configuration will be explained.

When the vehicle (not shown) tilts in the front-rear or left-right direction, the inner sphere 2 acts to maintain its initial posture and shows the degree of inclination, but the bubbles 5 housed in the bubble concealing part 4 are caused by the surface tension of the liquid 3. As a result, it maintains its approximately spherical shape and does not enter the narrow gap between the spherical container 1 and the spherical surface of the inner sphere 2 again.

Since the present invention has the above-mentioned structure and function, it is possible to prevent air bubbles from coming out to the front of the inclinometer with a simple structure, and the entire structure can be improved without taking the trouble of protruding an air reservoir like in the past. There are effects such as miniaturization.

Claims (1)

[Scope of utility model registration request] Inside the spherical container 1, an inner sphere 2 and a liquid 3 such as oil having the same specific gravity as the inner sphere 2 are stored, and the inner sphere 2 always maintains a horizontal posture and functions as an index with respect to the spherical container 1. In the inclinometer, a bubble hiding part 4, which is a step-shaped recess, is formed at the approximate top of the inner sphere 2, and the bubbles 5, which rise and collect in the liquid 3 such as oil due to the difference in specific gravity, are stored in the bubble hiding part 4. An inclinometer that is characterized by its ability to move easily.
