Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spirit level capable of measuring horizontal and tilt angles by reading a scale on which tilt angles are displayed according to the degree of deflection of a needle.

[0002]

[Prior art]

 Conventionally, as the structure of a level that reads the scale in which the tilt angle is displayed according to the degree of deflection of the needle, the needle is pivotally supported directly on the front side of the display plate, and a weight is attached to the lower end of the needle. The weight is always stable in the vertical direction.

[0003]

[Problems to be solved by the device]

 However, the level is not very sensitive. Therefore, various improvements have been made in the past by reducing the bearing resistance of the needle and increasing the weight of the weight in order to improve the sensitivity, but the needle stably stops the rotation of the weight. It took a lot of time before I could do it, and it was difficult to measure. In addition, if the needle movement is too sensitive, there is a problem that it is troublesome because it is easily damaged unless care is taken in handling and storing the level.

The present invention provides a spirit level that has good sensitivity and is extremely easy to handle.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, that is, in order to improve the sensitivity of the needle and to give a brake to the movement of the needle, it is possible to seal the scale with the inclination angle displayed on the surface. In the transparent container, a support rod having a thin indicator plate attached to the tip and a weight attached to the lower end is rotatably supported, and the inside of the container is filled with a braking fluid. In addition, a long rectangular parallelepiped base is fixed to the lower part of the container so that it can be stably placed on the measurement surface. In addition, a convenient horizontal confirmation lens and auxiliary scale are provided on the top of the side of the container for convenient horizontal confirmation and horizontal correction.

[0006]

[Action]

 Next, the operation of the present invention will be described. First, the case of measuring the tilt angle will be explained. When the horizontal base (10) of the present invention is placed on the measurement surface, the transparent and hermetically sealed container (1) tilts and the weight (4) moves to stabilize the force in the vertical position. To work. Then, in the container (1) that can be sealed, since the inside of the container (1) is filled with the braking liquid, the flat surface of the indicator plate (2) and the surface area of the weight (4) larger than before are The braking force by the braking fluid works, the indicating plate (2) stops in a much shorter time than the conventional one, and it can be immediately read in a stable state. As described above, by mounting the large weight (4), the sensitivity is improved and the measurement can be performed immediately. Moreover, by using a thin plate for the indicator plate (2), if the eye position shifts from the front when reading, the side that is displaced along with the plate thickness can be seen, so by looking at the position of only the plate thickness. You can easily see the correct position of your eyes. Therefore, the measured value can be read at the exact position of the eye, and the accurate measurement can be performed. Moreover, even if an impact force is applied to the level, it is alleviated by the braking fluid and the contents are protected, so handling and storage of the level becomes very easy.

When the present invention is used to install an installation tool or device such as a bathtub, those things are placed in the installation place. Then, the product of the present invention is placed on these flat portions. After placing, read the auxiliary scale (8) for horizontal correction attached to the top of the side of the container (1). If the value is shifted by 2 scales to the right, for example, it is easy to see that the right side is 2 centimeters higher per meter. Therefore, if a plate with a thickness of 2 centimeters per meter is placed on the bottom surface on the left side and the height is increased, horizontal installation can be easily performed. Also, at this time, by looking at the horizontal confirmation lens (9) attached to the center of the auxiliary scale (8) from above, it is enlarged whether or not the indicator plate (2) is correctly aligned at the 90 degree position. Since you can see it, you can check the horizontal level accurately and easily. When installing a bathtub, etc. in this way, by using the product of the present invention and putting in a concrete thing with a height of several values underneath, it becomes possible to easily perform horizontal installation, and the installation time Can also be shortened. Since a long rectangular parallelepiped horizontal base (10) is fixed to the lower part of the container (1), the placement of the measurement surface is stable.

[Effect of device]

 According to the present invention, a thin indicator plate (2) can be mounted at right angles to the rotation direction inside a sealable and transparent container (1) with a scale (7) displaying an inclination angle on the surface. By attaching a large weight (4), the pointing sensitivity is improved, and when reading the pointing plate (2), if the position of the eyes shifts from the front, the plate thickness and its side will enter the eyes and the plate thickness. With the above thickness, the accurate position of the eyes can be immediately known, so the reading becomes accurate. Further, in the above-described state, since the container (1) is filled with the braking liquid in the present invention, the flat surface of the indicator plate (2) is braked by the braking liquid and the weight (4) also has a large surface area, so the braking liquid is large. The braking force is also increased, the needle stops in a much shorter time than the conventional one, it can be read immediately in a stable state, and the content is protected by the braking fluid even if the impact force is applied to the level. , The handling and storage of the spirit level became very easy.

By attaching the horizontal confirmation lens (9) and the auxiliary scale (8) to the top of the side surface of the container (1) of the present invention, the reading of the indicating plate (2) at the 90-degree position can be enlarged. Since this can be done, horizontal confirmation is accurate and easy. Also, when installing a bathtub or the like, by using the product of the present invention, it is possible to easily understand the amount of deviation per meter by simply observing the deviation of the auxiliary scale (8), and the end in the inclined direction. A horizontal installation can be easily performed by inserting a part with a height corresponding to a few deviations and lifting it. Therefore, with this auxiliary scale (8), it is possible to easily prepare an appropriate thickness, or grind a thick one to prepare a predetermined height, and to install an installation tool or device. It is extremely simple and can be done in a short time compared to the conventional method.

Further, by mounting a long rectangular parallelepiped horizontal base (10) on the bottom of the container (1), the placement of the measurement surface is stabilized.
