Abstract
The utility model discloses a laser range finder, including distancer support, distancer body, this internal laser emitter that is equipped with, mil deflection sensor, the body surface is equipped with the operating portion, display screen, angle deflection adjust knob. Its characterized in that: range finding frame stabilizer blade forms by four stabilizer blades, but the rotation of independence and freedom to different length, the distancer body also can be rotatory 180 around the rotation axis, just fixes in the optional position. This internally installs two laser emitter at laser range finder, and laser emitter is according to fixed orientation lasing, and similar triangle -shaped principle at this internal angle displacement sensor that can measure and write down the laser emitter corner that still installs, is recycled to angle lasing that another laser emitter can deflect necessarily, can measure distancer apart from the distance of the object that awaits measuring and the length of the object that awaits measuring itself simultaneously, and respectively the demonstration on two display screens. Simple structure, low cost, easy operation, it is convenient directly perceived.
Description
Technical field
The utility model relates to field of engineering technology, particularly to a kind of similar triangle theory laser ranging instrument.
Background technology
It is presently used for the measuring appliance of scientific experiment and engineering in addition to chi has, the most useful mark post cooperation apparatus measures, and some laser ranging instruments.Wherein the range finding of standard rule tool also exists length limited and some object under test inconvenience survey crew measures；Utilizing mark post to coordinate apparatus measures then to need many people to coordinate, this easily causes error and labor intensive resource；And existing laser ranging instrument, can only the independent measurement distance away from object under test or the length of object under test itself, there is certain limitation；Also some laser range finder device have employed the transmission device such as telescope and worm screw turbine, the highest to distance mearuring equipment required precision, expensive, and is inconvenient to carry.
Utility model content
Problem to be solved in the utility model is to provide a kind of easy to operate and practical laser range finder.
The utility model be employed technical scheme comprise that, a kind of laser range finder, including rangefinder support (1), rotary shaft (2), rangefinder body (3), display screen one (301), display screen two (302), operating portion (303), adjusting knob (304), rangefinder shell (4) and range finding frame leg (5), it is characterized in that: described range finding frame leg (5) is placed on the ground, rangefinder support (1) is arranged in range finding frame leg (5), rangefinder shell (4) is arranged in range finding frame (1), rangefinder body (3) can be dismantled from rangefinder shell (4) easily and install, convenient and practical.
Range finding frame leg (5) of this rangefinder is made up of four legs, can independence and freedom rotate to different length, to adapt to different landform, rangefinder body (3) also can around rotary shaft (2) rotate 180 °, and it is fixed on optional position, to measure the object under test being in diverse location and angle.
When the most exigent precision of surveyed data, it is also possible to rangefinder body (3) is disassembled from rangefinder shell (4) and measures work.
Two generating lasers are installed in this laser range finder body (3), one generating laser launches laser by fixing direction, the deflectable certain angular emission laser of another one generating laser, it is also equipped with can measuring and the angular displacement sensor of recording laser transmitter corner in rangefinder body (3), recycling similar triangle theory, the rangefinder distance away from object under test and the length of object under test itself can be measured simultaneously, it is respectively displayed on display screen one (301) and display screen two (302), the convenient and swift data obtaining wanting to measure of the personnel that are convenient for measuring.
Beneficial effect: synthesis improvement on the distance mearuring equipment and simple chi tool measuring appliance of existing complexity so that laser ranging instrument is simple to operate, with low cost, measures accurately.The utility model is novel in design, adapts to no terrain environment, has good market prospects.

Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is described in detail.
As shown in Figure 2, range finding frame leg (5) of this rangefinder is made up of four legs, can independence and freedom rotate to different length, to adapt to different landform, rangefinder body (3) also can rotate 180 ° around rotary shaft (2), and it is fixed on optional position, to measure the object under test being in diverse location and angle.
As it is shown on figure 3, when the most exigent precision of surveyed data, it is also possible to rangefinder body (3) is disassembled from rangefinder shell (4) and measures.
As shown in Figure 4, two generating lasers are had in this laser range finder body (3), it is arranged at the A point of schematic diagram 4, one generating laser launches the AB direction in laser i.e. figure by fixing direction, AC direction in the deflectable certain angular emission laser i.e. figure of another one generating laser, it is also equipped with can measuring and the angular displacement sensor of recording laser transmitter corner in rangefinder body (3), distance d between BC on deflection angle theta and rangefinder can be measured；In rangefinder, distance a between AB also determines that, laser beam AD and object under test are vertically intersected on a D, can be by the principle of reflection of laser at A point position installation laser pickoff, utilize formula a+b=ct/2, can calculate rangefinder distance b between object under test, display is on display screen one (301)；Recycling similar triangle theory, length s=(a+b) d/a of object under test itself, display is on display screen two (302), and the personnel that are convenient for measuring obtain measurement data efficiently.
