Abstract

The utility model provides a laser level-meter, which is composed of a base 9 which is provided with a horizontal reference plane 8 and a suspension reference plane 6, a laser generator 2 which is installed on the front end of the base, a tailcone 5 which is installed on the tail end of the base, a horizontal bubble tube 10 and a suspension bubble tube 7 which are installed in the base. The laser level-meter has the advantages of wide use, skillful and cheap performances, simple and convenient performances, large measuring distance and high accuracy.

Description

Laser leveler

The utility model relates to a kind of level meter, particularly relates to a kind of laser leveler.

In work progresss such as civil engineering work, decoration industry, often need to determine and the insolation level point that the method that adopts is a transparent hose water level observation at present, is commonly called as the par pipe.This traditional method wastes time and energy inaccurate, each use will be toward an amount of water of filling in the not only thin but also long flexible pipe, drain the air bubble in the pipe patiently, the many water of water cost a lot of times adjustment less, having changed the measuring point of another height must operate once again, if distance is far away slightly, tens meters long water pipe operation is more difficult, and accuracy is very low.Certain level point is measured also has mechanical type visual derection level instrument, spirit-leveling instrument at present, and that is a whole set of Special Equipment that needs the professional to use in specific occasions, and not only complicated loaded down with trivial details but also heavy costliness can at will not used whenever and wherever possible.

The purpose of this utility model, provide a kind of dexterity, inexpensive, measure that distance is big, degree of accuracy is high, general workman can use whenever and wherever possible, time saving and energy saving laser leveler.

Laser leveler of the present utility model, it is characterized in that it by have the pedestal of level reference with the reference field that dangles, be installed in the pedestal front end parallel with level reference and with the vertical laser generator of the reference field that dangles, be installed in the pedestal rear end and with the coaxial tail cone of laser generator, be installed in horizontal bubbler tube parallel in the pedestal, be installed in the bubbler tube that dangles parallel in the pedestal and form with the reference field that dangles with level reference.

The shape of pedestal (lateral plan) is spill, rectangle or other shape.

Laser leveler of the present utility model, purposes is wide, both can measure level point, can measure again and dangle a little, simultaneously also be one can the insolation level degree and the surveyor's staff of verticality; It is big to have the distance of mensuration, and the degree of accuracy height is easy and simple to handle, dexterous inexpensive advantage; It is an improvement greatly of traditional assay method in the work progresss such as civil engineering work and decoration industry.

Be described in detail the concrete structure and the principle of work of the utility model laser leveler below in conjunction with accompanying drawing.

Accompanying drawing is the side schematic view of a kind of embodiment of the utility model laser leveler.1 is laser emission port among the figure, the 2nd, and laser generator, the 3rd, shift knob, the 4th, end cap, the 5th, tail cone, the 6th, the reference field that dangles, the 7th, the bubbler tube that dangles, the 8th, level reference, the 9th, pedestal, the 10th, horizontal bubbler tube.

As shown in the figure, the matrix cast aluminium pedestal 9 of thick 20mm has the level reference 8 and the reference field 6 that dangles, and other plane is also parallel with reference field or vertical.Adopt the commercially available complete horizontal bubbler tube 10 and the bubbler tube 7 that dangles, the square and circular reserved location adjustment that is installed in the pedestal is fixed.Laser generator 2 is selected commercially available laser bar for use, diameter 13.5mm, the laser beam irradiation distance can reach about 100 meters, and laser generator 2 penetrates the cylindrical hole adjustment of pedestal 9 front ends and fixes, end cap 4 can screw off the replacing button cell, and laser beam penetrates from transmitting aperture 1 when pressing switch 3.Tail cone 5 is installed in the rear end cylindrical hole adjustment of pedestal 9 and fixes.When determining level point, by being pressed on the reference point, make the bubble of horizontal bubbler tube 10 be positioned at the central scale of pipe tail cone 5, this moment, the point of irradiation of laser beam was the level point of reference point.As a same reason, can use dangle bubbler tube 7 and laser beam to measure dangles a little.Also available two reference fields and two bubbler tubes are measured the levelness on plane and the verticality of facade respectively.

Claims

1, a kind of laser leveler, it is characterized in that it by have the pedestal (9) of level reference with the reference field that dangles, be installed in pedestal (9) front end parallel with level reference and with the vertical laser generator (2) of the reference field that dangles, be installed in pedestal (9) rear end and with the coaxial tail cone (5) of laser generator 2, be installed in horizontal bubbler tube (10) parallel in the pedestal (9), be installed in interior the dangle bubbler tube (7) parallel of pedestal (9) and form with the reference field that dangles with level reference.
