Description

Horizontal angle measuring instrument {A measuring device}

The present invention relates to a horizontal angle measuring device for checking the horizontal state of an object in a construction site or a factory, and in particular, to precisely measure the angle of the object to be adjusted so that the object can be adjusted to a required position, as well as compact. It consists of a horizontal angle measuring device that can be made down the manufacturing cost in the structure.

In general, the level is widely used in the construction site or factory to measure the horizontal.

In addition, various types of converted levelers have been proposed to suit the purpose of use.

As an example of such a conventional leveler, Japanese Patent Application Laid-Open No. 2000-283761, which was published in Japan on October 13, 2000, has been proposed.

Japanese Patent Application Laid-Open No. 2000-283761 discloses a reference plane in contact with the measurement plane 3 on the bottom surface of the base body 2 having the bubble tube 1 measuring the horizontality on the upper surface as described in FIG. 1 and the claims. In the level (5) provided with (4) is provided, the light emitting body (7) having a light emitting portion (6) for emitting a straight light such as a laser light is provided, and the light emitting body (7) has a horizontal view When the bubble tube (8) is installed and the light emitting body (7) is installed on the level (5), the light emitting body (7) can be installed horizontally by the bubble tube (8). (7) is provided in the leveler (5), so that the straight light from the light emitting portion (6) of the light emitting body (7) is irradiated in parallel with the reference plane (4) of the leveler (5). .

In addition, when the light emitting body 7 is installed on the level 5, the light emitting main body 7 is provided with a fixing means 9 for fixing the light emitting main body 7 to the level 5; 9), the light emitting main body 7 is horizontally supported on the basis of the horizontal index by the bubble tube 8.

Japanese Unexamined Patent Application Publication No. 2000-283761 projects a progressive light beam, such as a laser beam, from the light emitting portion 6 of the light emitting body 7 so as to roughly measure a long horizontal state.

However, this conventional Japanese Patent Application Laid-Open No. 2000-283761 has a problem in that it is not suitable for use in construction sites where breakage and loss of tools are frequent because a light emitting body having a light emitting unit is provided and manufacturing cost is high at the time of manufacture. there was.

In addition, there is a problem that it takes an excessive amount of time to correct the object because there is no means for knowing exactly how many degrees the horizontal state is inclined.

That is, the conventional leveler is somewhat unsuitable for use in construction sites where the cost is high and the tools are frequently damaged and lost, and there is an excessive amount of time for correcting an object whose exact inclination of the object to be measured is unknown. There have been various problems such as deterioration of work efficiency, etc. In addition, a vertical and horizontal measuring device of Utility Model Registration No. 20-0207033 has been proposed in Korea. The horizontal measuring device includes a measuring body provided with a measuring surface for measuring an object as described in the registered claims, and an angle display unit for measuring horizontal and vertical angles on an outer circumferential surface of the measuring body to form a transparent body on one side of the measuring body. The body portion provided with, the liquid portion provided with a predetermined volume inside the body portion, and in response to the water surface of the liquid It is characterized in that it comprises a measuring device unit provided with an indication unit for indicating a constant to the angle display unit. However, such a conventional vertical, horizontal measuring device can measure the angle by buoyancy, but by measuring the angle by buoyancy alone Of course, the precise angle cannot be measured, and there is a problem that the more precise measurement can not be performed because the indicator needle is restricted by the shaft.

The present invention has been made in view of the above-described various problems, and an object of the present invention is to accurately measure the inclination angle of a target object in two times so as to double the work efficiency by quickly measuring an object to measure the inclination. In addition, to provide a horizontal angle measuring device that can reduce the manufacturing cost during manufacturing by using the generalized parts so that anyone in the construction site, such as frequent damage and loss of tools can be used casually.
