CN2404099Y - Position indicator - Google Patents

Abstract

The utility model relates to a position indicator, particularly a position indicator for measuring directions, which can measure directions and can also be positioned. The utility model is mainly composed of a dial disc having an inner circle of graduation values and an outer circle of graduation values, needle teasing gear wheels of an inner indicating needle and an outer indicating needle, a circular disk of a teasing needle, an amplifier, etc. The inner indicating needle rotates at one lattice through the action of mechanical force, and the outer indicating needle rotates at one circle in the meantime. In direction measurement, so long as a sighting device faces an object, the inner indicating needle rotates and coincides with a graduation line in a compass through the amplifier, so the indicated value of the outer indicating needle is the measured direction. When the utility model is used for determining directions and shooting direction of a cannon, the operation sequence is contrary to the operation sequence of measuring directions.

Description

A kind of tax is to orientator

The utility model relates to a kind of orientator, and especially a kind of can the tax to the tax that can locate again to orientator belongs to tax to field of locating technology.

At present, the tax of using on the organizational equipment mainly contains two kinds to instrument: the one, bearing circle, two is 62 same form north arrowes, the deficiency that the former mainly exists is: volume is big, complicated operation, directed, compose long to the required time; Compose to difficulty at complex-terrain, night, rain, snow, greasy weather gas, compose to low precision, operate miss and systematic error are also bigger; The deficiency that the latter exists is: have only a graduation on the index dial, minimum mil is 20, judges that direction orientation time error is big; Needle sensitivity is lower, and friction factor is big between the needle shaft, and damping is bigger; Do not have leveling bubble, level can't accurately just be advised.

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, provide a kind of energy fast, accurately direction finding, directed be not subjected to weather influence directly for cannon compose to the high precision tax to orientator.

For achieving the above object, the technical solution that the utility model adopts is: a kind of tax is to orientator, mainly by shell, index dial, train wheel bridge, lower plate, the power wheel parts, dial pin gear, dial the pin disk, compass, compositions such as central shaft and elasticity spring, in its special character is to have on the index dial, outer two circle scale values, the inner ring scale is divided equally 60 equal portions, equal 100 equal portions of outer ring scale, be connected with outer pointer wheel with interior pointer wheel respectively, two pointer wheel are coaxial, interior pointer is housed on the interior pointer wheel, outer pointer is housed on the outer pointer wheel, interior pointer and outer pointer respectively interior pointer wheel with outside rotation synchronously under the drive of pointer wheel, in the indication, EXT scale value, outer pointer are rotated a circle, and interior pointer synchronously rotates lattice; There is a level meter at the positive center of index dial.

Above-described tax is to orientator, and its characteristics also are also to be equipped with on the index dial illuminator and an amplifier.

The utility model compared with the prior art, it is little, simple to operate to have a volume, tax is short to, orientation time, not influenced by landform, weather, and systematic error is little, the precision advantages of higher, be not only applicable to military hardware, also can be used for fields such as geologic prospecting, navigation, navigation.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, tax described in the utility model is by shell 1 to orientator, index dial 2, train wheel bridge 3, interior pointer wheel 4, outer pointer wheel 5, lower plate 6, rotor wheel parts 7, dial pin gear 8, dial pin disk 9, interior pointer 10, outer pointer 11, compass 12, central shaft 13 and elasticity spring 14 are formed, in having on the index dial 2, outer two circle scale values, the inner ring scale is divided into 60 equal portions, the outer ring scale is divided into 100 equal portions, be connected with outer pointer wheel 5 with interior pointer wheel 4 respectively, two pointer wheel are connected with index dial is coaxial, pointer 10 in being equipped with on the interior pointer wheel 4, outer pointer 11 is housed on the outer pointer wheel 5, interior pointer 10 and outer pointer 11 respectively interior pointer opinion 4 with outside rotation synchronously under the drive of pointer wheel 5, in the indication, the EXT scale value, outer pointer 11 rotates a circle, and interior pointer 10 rotates lattice accordingly; There is a level meter at the positive center of index dial 2, and night time operation accurately aligns for convenience, and an illuminator and an amplifier also are housed on the index dial 2.

When needs are directed, the sighting device of composing on orientator is concentrated one's gaze on target and made leveling bubble placed in the middle, and when compass was static, pointer made it accurately to align with the compass arctic in rotating, when the outer pointer of synchronous rotation is static, see that the scale value of reading inside and outside pointer indication promptly is required fixed direction.

When needs compose to the time, the direction that inside and outside pointed is composed is rotated and is composed to the orientator housing, makes the compass arctic accurately align interior pointer, promptly gives weapon or equips desired direction.

In the time will locating, if accurately measure need the location o'clock to the direction of the known point of a known coordinate with apart from S, from this known point by reverse direction to the straight line that distance of strokes and dots of need location is S, can learn that wanting the accurate position of anchor point is coordinate; Also available resect location.

When utilize composing when orientator comes indicating target, only need on the basis of above-mentioned location, measure anchor point to direction and the distance of wanting indicating target, get final product the coordinate of impact point, thereby definite its position.

Claims (2)
