Abstract
The utility model relates to a compass measurer, which is a precision instrument used for observing the azimuth of the geomantic omen. The compass measurer is mainly composed of a compass rose (the Eight Diagrams disk), a surveillance mirror of vertical angle, an adjuster of azimuthal angle, a displacement mechanism, a level bar and a tripod. The observed accuracy of the compass rose is obviously improved. The traditional skill of observing the geomantic omen of China is carried forward.
Description
The utility model relates to a kind of surveying instrument, and the compass rose especially for observation orientation, geomantic omen is commonly called as Eight Diagrams dish.
Utilizing compass rose observation treasured place is folk tradition skill.But, the rolling up of population, buildings intensive observed survey with two, often causes the inaccurate of judgement.
The purpose of this utility model is that a kind of observation compass rose measuring instrument accurately will be provided.
The purpose of this utility model is achieved in that compass rose and right angle surveillance mirror is combined as a whole.The X-axis of two rectangular coordinate systems in compass rose and the right angle surveillance mirror is space parallel lines, two parallel lines in the same plane that two Y-axis are vertical X-axis.Compass rose and right angle surveillance mirror can rotate or move left and right synchronously, and the right angle surveillance mirror can swing up and down.Because the right angle surveillance mirror is actually a right angle refracting telescope of being furnished with rectangular coordinate, under the said structure condition, it can obviously improve the observation accuracy of compass rose.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
Fig. 1 is a stereographic map of the present utility model.
Fig. 2 is a three-dimensional exploded view of the present utility model.
Fig. 3 is a right angle of the present utility model surveillance mirror swing synoptic diagram.
Fig. 4 is a right angle of the present utility model surveillance mirror structural representation.
Fig. 5 is an azimuth adjustment device worm gear pairs engagement cut-open view of the present utility model.
Fig. 6 is that azimuth adjustment device worm gear pairs of the present utility model breaks away from cut-open view.
Fig. 7 is the view of displacement mechanism of the present utility model.
Referring to Fig. 1,2, the utility model is by compass rose 1, support 2, and azimuth adjustment device 3, knob 4, spring pin 5, displacement mechanism 6, tripod 7, right angle surveillance mirror 8 is formed.
Azimuth adjustment device 3, by housing 38, empty worm-wheel shaft 31, nut 32, worm screw 33, end cap 34, ball pivot seat 35, mandrel 36, slide 39 is formed.Housing 38 has worm gear axocoel, worm screw chamber, ball pivot seat chamber, end cap thread cavity, spring pin chamber, slotted hole 37 and four fixed claws.On the hollow worm-wheel shaft 31 shaft shoulder is arranged, after guaranteeing to assemble, the gap of compass rose and housing 38.
Referring to Fig. 2,5,6, hollow worm-wheel shaft 31, behind the insertion mandrel 36, in the housing 38 of packing into, compass rose 1, hole 13 and 25 end of support circle hole sleeve are solidified as a whole its three with nut 32 on the shaft shoulder top of hollow worm-wheel shaft.
Turning knob 4 like this, compass rose and right angle surveillance mirror are rotated together, the fine setting position angle, if move knob 4 along slotted hole 37, make worm gear and worm screw break away from engagement, stir compass rose 1 with hand, can make its any rotation, unclamp knob 4, under the effect of spring pin 5, worm gear and worm screw recover engagement.
Referring to Fig. 2,7, displacement mechanism 6 is by base plate 67, slide block 61, and tooth bar 62, groove seat 63, gear 65, knurled shaft 66 is formed.
Gear 65 is packed in the chamber, inserts knurled shaft 66, will install the base plate 68 of slide block 61 and tooth bar 62 again, pushes in the groove seat 63 along dovetail groove 64.
Referring to Fig. 1,2, four fixed claws with azimuth adjustment device 3 are fixed to above the base plate 68, three lug 67 usefulness of groove seat 63 are regulated bolt 72 be fixed on the holder 71 of tripod 7, therefore, can utilize three legs of tripod 7.The levelness of coarse adjustment compass rose 1 then, is regulated bolt 72 again and is finely tuned, and rotates knurled shaft 66, can make compass rose 1 and right angle surveillance mirror 8, about same moved further.
Referring to Fig. 4,1, right angle surveillance mirror 8 is made up of eyepiece 81, coordinate mirror 82, prism 83, object lens 84 and cylindrical shell 85.Be actually the right angle refracting telescope of being furnished with rectangular coordinate, it is to be fixed in the sleeve 21 by clamping screw 24.When focusing, the tight bolt 24 of releasable lock moves forward and backward in sleeve 21.
Generally speaking, adopt the utility model that the observation accuracy of compass rose is obviously improved, make motherland may survey the traditional technology in geomantic omen, develop.
