Abstract
A kind of laser measurer of the utility model, relate to take measurement of an angle, the specific purpose tool of level height, laser or infrared generator, protractor, pedal line is used to cooperatively interact, make laser or infrared ray light parallel with the rectangular wire of protractor [5], and protractor can rotate by demand 360 degree of any levels or rotate up and down.Solve existingly to take measurement of an angle, level height error is large, efficiency is low, labour intensity is large problem, be mainly used in the measurement of dimensional measurement teaching and building ground level height.
Description
Technical field
The utility model relates to the specific purpose tool of the teaching of a kind of dimensional measurement and level height measurement.
Background technology
When the teaching aid of existing dimensional measurement teaching needs, temporary erection, during operation, measurement point is seen at the edge taking aim at protractor with eyes.Aiming in the process seen, easy shaking volume hornwork, error is large, and by kopiopia, student is not dense to its interest, grasp method, knowledge weak effect, needs to improve.Specialty for level height is measured, technician measures difference in level with spirit-leveling instrument, from ground to roof, almost every one deck all will measure difference in level between several difference (this is because in construction process, the gimmick of different workmans is different, and the size heterogeneity of batches of materials can produce the difference of height), according to the height of the data correction difference measured, make it to reach designing requirement.But measure with original spirit-leveling instrument, the scope observed on scale is large, and inevitable errors is also large, and only sees that a people of spirit-leveling instrument can see.In order to prevent error excessive, everyone sees once just to only have several technician, then averages, pretty troublesome, easily encounters spirit-leveling instrument flat board again, causes the movement of spirit-leveling instrument flat board.Flat board is every slightly to be moved once, and the measurement data that front and back are twice all can not be identical, needs to upgrade.
Utility model content
The utility model provides a kind of laser measurer, solve existingly to take measurement of an angle, level height error is large, efficiency is low, labour intensity is large problem.
The utility model is made up of base, adjustment bolt, pedal line, pillar, protractor, laser or infrared generator, elasticity bolt, balanced adjustment bolt, power switch, Rotational Cylindrical.The light that laser or infrared generator produce is parallel with the rectangular wire of protractor, and luminous point impinges upon on measurement point, is suspended on elasticity bolt, can horizontally rotate with Rotational Cylindrical 360 degree is arbitrary or rotates up and down.Wherein by base being made steady to the adjustment of adjustment bolt, make pillar perpendicular to surface level.To the adjustment of balanced adjustment bolt, protractor is balanced, make protractor loosen flexibly or fix to the adjustment of elasticity bolt, Rotational Cylindrical can 360 degree of demands of pressing rotate.Power switch controls laser or infrared generator produces light source, and light is parallel with the rectangular wire of protractor, irradiates on thing and forms luminous point.
Beneficial effect: structure of the present utility model is simple, cost is low, operation is light, work efficiency is high, durable, can measure various data efficiently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of the utility model Fig. 1.
Embodiment
The light that laser or infrared generator produce is parallel with the rectangular wire of protractor, and luminous point impinges upon on measurement point, is suspended on elasticity bolt, can horizontally rotate with Rotational Cylindrical 360 degree is arbitrary or rotates up and down.By demand, base [1] is placed on solid place, adjustment bolt [2], makes base [1] steady, make pillar [4] perpendicular to surface level.When taking measurement of an angle, first loosen elasticity bolt [7], power-on switch [9], upwards (or downwards) amount of spin hornwork [5], laser or infrared generator [6] generation light source is controlled with power switch, light is parallel with the rectangular wire of protractor, irradiates on thing and forms luminous point.Luminous point is impinged upon on measurement point, slightly screws elasticity bolt [7], watch and record the angle that pedal line [3] and protractor [5] form, just can draw the angle needed for measurement.Error is little, and operation easily, can excite the interest that student operates.When measuring level height, first loosen elasticity bolt [7], adjustment balanced adjustment bolt [8], pedal line [3] is aligned with 90 degree of scales of protractor [5], screw elasticity bolt [7] again, power-on switch [9], rotate Rotational Cylindrical [10] by demand, make the luminous point of light according to reflecting on scale, corresponding data on scale record.By rotating Rotational Cylindrical [10] for several times, drawing the data on scale on several difference, thus drawing the level height of difference and the difference in level between them.Because the utility model measuring accuracy is high, error is little, ultrahigh in efficiency, several points in a building site only need a few minutes just can measure.
