Description

Laser level and vertical measuring instrument

The utility model relates to instruments, in particular to a laser level and vertical measuring instrument.

The level measuring instruments used in early building construction were based on the V-shaped water pipe or the horizontal bubble meter to make the reference line of the horizontal construction; in addition, the vertical measuring instruments were based on the plumb weight or the vertical bubble meter to make the reference line of the vertical construction. Due to the production of its construction reference line, only one reference line can be obtained by the measuring instrument at a time, and the reference line of the measuring instrument must be replaced in another measurement to obtain the reference line. Therefore, the traditional measuring instrument does not have construction Convenience, and a vain waste of working time, has gradually been replaced by horizontal and vertical measuring instruments with laser projected light spots.

At present, the laser level and vertical measuring instrument developed, such as the Taiwan Patent Publication No. 325882, the patent named "Laser (Laser) Leveling and Vertical Measuring Instrument", mainly includes: a cavity shell, a tube inner tool The vertical tube and the bracket for erecting the shell in the laser component, wherein one end of the vertical tube is fixed with a spherical lens supported by the ball, and the other end of the tube forms a transparent space, and a beam splitter is installed near it , a laser generator is installed near the bottom of the lens and the beam splitter in the tube, so that the laser light can be directed to the spherical lens and the beam splitter, thereby generating horizontal split light and vertical light, which can be used for vertical and level indication.

Although the above structure can theoretically achieve the effect of vertical and horizontal projection reference points, in actual production, it is not easy to maintain the accuracy of the center axis after rolling balance between the bottom surface of the spherical lens, the vertical tube and the ball. Control, because of the design and manufacturing accuracy of the curved surface of the spherical lens, the accuracy of the vertical tube and the bottom surface of the spherical lens, and the accuracy of the contact between the ball and the bottom surface of the spherical lens, etc., plus its high production cost , therefore, cannot meet the needs of mass production.

Taiwan Patent Announcement No. 330689, titled "Horizontal and Vertical Surface Laser Indicator" patent, which is mainly composed of a transparent container, a buoy with a built-in laser emitting component and a bracket, wherein the center of gravity of the buoy is Constantly falling in the center, one end of the cylinder emits horizontal laser light, and the other cylinder body emits vertical laser light upwards, and a needle shaft is installed in the center of the cylinder, and the needle shaft intersects with the body of the buoy at a vertical angle Fill the transparent container with liquid to the lower edge of the buoy, make the buoy float upright on the horizontal plane, and keep the laser light emitted from the floating surface horizontal and vertical for plane measurement.

Although the above-mentioned structure can achieve the effect of vertical and horizontal projection reference points in theory, in actual operation, the liquid in the transparent container must be kept in a static state, that is, there is no shaking at all, so that the buoy can be used. The light spot projected by the laser component is used as the reference for measurement. Since the transparent container is often moved when it is adjusted and erected, it is easy to cause the liquid inside to shake, and because the buoy occupies a large floating area on the liquid surface, it must be used Only when the liquid surface is very calm can the stability of the buoy be maintained, the adjustment operation is very time-consuming and the work efficiency is low.

Another example is Taiwan Patent Announcement No. 325883, titled "Laser Horizontal, Vertical, and Angle Measuring Device" patent, which mainly runs through a through hole in the center of the base of the measuring device, and is pivoted by bearings, shaft rods, and nuts. It is set on a rotatable revolving seat, and a laser light pen is embedded in the semicircular groove above the seat body, and a gear is arranged on the circumference of the lower part of the revolving seat, which can be driven by a servo motor next to it to adjust the rotation of the revolving seat. The irradiation angle of the laser light pen, and the vertical and horizontal positions of the base are embedded with level gauges, and at least three screw holes are drilled at appropriate positions on the edge of the base, so as to lock the screw to fix the adjusting bolt, and the upper end of the adjusting bolt It is a rotary knob, the middle car is made into an external thread section, and the end is made into a pointed cone, which can be locked in the screw hole of the base to adjust the level.

Although the above structure can be connected to the receiver at the servo motor and the laser light pen respectively, and the angle of the rotating seat is adjusted and the laser light pen is switched on and off by using the remote control to start the servo motor, it is hoped that one person can achieve the goal of saving labor by remote control and drawing reference points , but if the driving power required by the servo motor is an internal battery, it will consume a lot of power, and the battery must be replaced frequently. If it is an external power supply, it will often cause a lot of inconvenience to extend the power line on each floor of the construction site .

In addition, in the practical application of general laser level and vertical measuring instruments, because they are mainly installed on the ground level by angle brackets for horizontal and vertical measurements, the construction scope is limited to indoors. As for outdoor wall construction, users must Standing on the scaffold for operation, but the angle frame of the measuring instrument is not easy to erect and inconvenient to operate, so the measuring instrument has not been seen in outdoor wall construction occasions, and it is true that the relevant application technology structure is not ideal.
