Abstract
The utility model relates to a laser compass, which comprises a pedestal, a laser indicator device, a magnetic compass and a reflector barrel; a dial is fixed inside a top end of the pedestal by a glass-ceramic ball bearing; the magnetic compass is arranged in the middle on the top end of the dial; the top of the magnetic compass is fixed on the pedestal by two intercrossed pull wires; a concave groove is formed on a sidewall of the pedestal; the laser indicator device is arranged inside the concave groove; a laser emission hole forming an included angle of 90 DEG with the concave groove is arranged on one side of the concave groove; and the reflector barrel is arranged inside the laser emission hole. The laser compass provided by the utility model has the advantages of simple structure, convenience in use and small error, and being capable of indicating the direction conveniently. Compared with the existing visual measurement, the laser compass provided by the utility model has better precision.
Description
Technical field
The utility model relates to a kind of laser compass.
Background technology
Compass is one of great four inventions of China, be the most ancient instrument of direction of measurement, existing compass comes from the Chinese uranology before bimillennium, and first magnetic compass 27BC is unearthed to the ancient tomb between the 209BC, it uses the star chart record with guide spoon, and we are called " compass " in today.
Compass comes direction indication by the principle of terrestrial magnetic pole, normally at base a magnetic pointer is set.Existing compass all is to comprise a base and magnetic compass, and magnetic compass is installed on the base and can rotates with direction indication with respect to base.For the ease of using, can also be provided with for scale or sign in susceptor surface.Utilize like this terrestrial magnetic pole principle, magnetic compass direction pointed is north.
Although this compass structure is simple, after relying on the magnetic compass direction indication, can only rely on range estimation to take one's bearings.The mistake that causes possibly direction so in the open air, and error is just larger in the smaller space such as indoor.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of laser compass simple in structure, easy to use.
Laser compass of the present utility model, comprise base, laser pointer device, magnetic compass and mirror barrel, the inner fixedly rotating disk of glass ceramics ball bearing that passes through in the top of described base, the top middle portion of rotating disk is provided with magnetic compass, the top of magnetic compass is fixed on the base by two draught lines of mutual intersection, one sidewall of base is provided with groove, inside grooves is provided with laser pointer device, one side of groove is provided with groove and becomes the laser of 90 degree angles to penetrate the hole, and the inside that laser penetrates the hole is provided with mirror barrel.
Laser compass of the present utility model, described laser pointer device is fixed on inside grooves by grab.
Laser compass of the present utility model, the distance between the central point of described laser pointer device and magnetic compass top end face is not less than 60 millimeters.
Compared with prior art the beneficial effects of the utility model are: laser compass structure of the present utility model is simple, easy to use, and error is little, can make things convenient for direction indication, and the existing range estimation mode of comparing has better accuracy.
Description of drawings
Fig. 1 is the structural representation of the described a kind of laser compass of the utility model embodiment;
Fig. 2 is the decomposition texture schematic diagram of the described a kind of laser compass of the utility model embodiment;
Fig. 3 be the described a kind of laser compass of the utility model embodiment cut-open view.
Among the figure:
1, base; 2, laser pointer device; 3, magnetic compass; 4, mirror barrel; 5, glass ceramics ball bearing; 6, rotating disk; 7, groove; 8, grab; 9, draught line.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As Figure 1-3, a kind of laser compass, comprise base 1, laser pointer device 2, magnetic compass 3 and mirror barrel 4, the inner fixedly rotating disk 6 of glass ceramics ball bearing 5 that passes through in the top of described base 1, the top middle portion of rotating disk 6 is provided with magnetic compass 3, the top of magnetic compass 3 is fixed on the base 1 by two draught lines 9 of mutual intersection, one sidewall of base 1 is provided with groove 7, groove 7 inside are provided with laser pointer device 2, one side of groove 7 is provided with the laser of 7 one-tenth 90 degree of groove angle and penetrates the hole, and the inside that laser penetrates the hole is provided with mirror barrel 4.
Laser compass of the present utility model, described laser pointer device 2 is fixed on groove 7 inside by grab 8.
Laser compass of the present utility model, the distance between the central point of described laser pointer device 2 and magnetic compass 3 top end faces is not less than 60 millimeters.
Laser compass of the present utility model is when concrete the use, base should use nonmagnetic substance, simultaneously for fear of disturbing magnetic compass, must use non magnetic bearing, laser compass structure of the present utility model is simple, easy to use, and error is little, can make things convenient for direction indication, the existing range estimation mode of comparing has better accuracy.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
