Description

Laser type horizontal vertical measuring instrument
The utility model relates to a kind of device of measuring degree of tilt.
Level, angle, vertical survey device be widely used in building, finishing and road and bridge design and construction and teaching.
A kind of multifunctional level-meter of CN2319782Y patent disclosure, be made up of annular linker, survey mark plate, measuring basis seat, annular linker is a sealed glass tubes, end to end circularizing, inject coloured antifreezing liquid in the pipe, can survey levelness, verticality and angle of inclination.The surveyor's staff of a kind of energy of CN2326938Y patent disclosure angle measurement degree, comprise blade, scale and globule formula level meter, the scale face of blade also has an inclinometer, inclinometer comprises angle index, pointer and needle pivot, 0 ° of scale mark of angle index can take measurement of an angle and day water levelling perpendicular to the long survey face of blade.A kind of multifunction level meter of CN2163368Y patent disclosure, an end or rectangle material middle part at drawing rule are provided with the level angle reflecting device, establish the arc sealed tube in this reflecting device, indicate angle index line and angle value in the relevant position of pipe, the mark of movable energy reveal competence angle position is housed in pipe.
The purpose of this utility model is to provide that a kind of measurement range is big, speed is fast, work efficiency and the high laser type horizontal vertical measuring instrument of degree of accuracy.
The utility model comprises base, adjustable column, protractor, support, laser bar, laser bar support, angle adjustment plate and weight.Adjustable column is located at the periphery of base.The lower end of support is connected with base, the upper end of support is connected with the center of protractor, the suspension line of weight is terminated at the center of protractor, the center of angle adjustment plate is connected with the central movable of protractor, establishing datum line on the angle adjustment plate also can rotate around its center, the bottom of laser bar is fixed on the laser bar support, axial and the angle adjustment plate datum line of laser bar is on same surface level, the laser bar support is connected with angle adjustment plate, and laser bar and angle adjustment plate can rotate around the center of protractor synchronously.
Owing to adopted laser bar and protractor, utilize the principle of linear propagation of light, extensible horizontal line and perpendicular line also form visual intuitively red spot, not only can measure level, vertical, and can take measurement of an angle, its measurement range is big, speed is fast, work efficiency is higher with degree of accuracy, all has been widely used in building and road and bridge Site Design, construction and finishing and teaching etc.
Fig. 1 is a structural representation of the present utility model.
As seen from Figure 1, the utility model is made up of base 1, adjustable column 2, protractor 3, support 4, laser bar 5, laser bar support 6, angle adjustment plate 7 and weight 8.Adjustable column 2 is located at the periphery of base 1, so that regulate the levelness of base.The lower end of support 4 is fixed on the upper end of base 1, and the center of the upper end of support 4, angle adjustment plate 7 is connected with the center of protractor 3 with the suspension line of weight 8 81 end threes.The bottom of laser bar 5 is fixed on the laser bar support 6, and the datum line 71 of the axis of laser bar 5 and angle adjustment plate 7 is on same surface level, and laser bar support 6 vertically extends the end in angle adjustment plate 7.Laser bar can rotate around the central synchronous of protractor 3 together with angle adjustment plate.The front end of angle adjustment plate is established display aperture 72.
