Abstract
The utility model provides an adapter ring for a measuring instrument. The adapter ring comprises an upper mounting base plate and a lower mounting base plate, an upper fixing groove is arranged on the upper plate surface of the upper mounting base plate, a lower fixing groove is arranged on the upper plate surface of the lower mounting base plate, the upper and lower mounting base plates are arranged in parallel, a plurality of corresponding mounting holes are formed between the upper and lower mounting base plates, a support bar is arranged in every two opposite mounting holes, and upper and lower ends of each support bar are connected with the upper and lower mounting base plates through adjusting screws. By means of the adapter ring for the measuring instrument, the distance between the upper and lower mounting base plates is adjusted through the adjusting screws on the support bars, so that the height of the instrument is changed; and the adapter ring is widely applicable to measuring instruments such as levels, theodolites and the like.
Description
Technical field
The utility model relates to a kind of surveying instrument, especially a kind of surveying instrument adapter ring.
Background technology
At present, the national standard such as " national first and second order leveling standard GB 12897-91 ", " hydroelectricity engineering survey standard SL 197-97 ", " building deformation specifications of surveys JGJ/T 8-97 ", " hydrology common survey standard SL 58-93 " and industry standard require the height of sighting line of measurement of the level must meet three energy reading demands of instrument; Height of sighting line (a lower reading) primary levelling of " national first and second order leveling standard " regulation is not less than 0.5 meter, second-order levelling and is not less than 0.3 meter." hydrology common survey standard " regulation, when height of sighting line can not meet the demands, requires to bury firmly scale stake underground, and builds firmly measuring platform or frame.In leveling work, owing to affected by instrument stand website geographic position of living in, though it is high that the size of the opening degree by adjusting the instrument foot rest is adjusted instrument, usually still can not meet the requirement that leveling norm is high to sight line, also easily cause the instrument unstability simultaneously and damage.Traditional way is to increase several websites that turn to measure, and such one is to have increased workload, the 2nd, strengthened measuring error, and reduced measuring accuracy.In triangulation, because being subject to geographic position of living in, transit frame website affects, and during observation, the elevation angle or the angle of depression are excessive, can't aim at and sight position, and systematic error is large, can't meet the specifications of surveys requirement, can only reselect reference mark, has increased greatly workload.
Summary of the invention
The purpose of this utility model is to provide a kind of surveying instrument adapter ring, can be regulated for the height of surveying instrument, to meet the demand of actual measurement work.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the surveying instrument adapter ring, it is characterized in that: comprise mounting base, lower mounting base, the upper face of upper mounting base and lower mounting base is respectively equipped with pickup groove and lower pickup groove, upper mounting base and lower mounting base be arranged in parallel, be provided with the mounting hole of a plurality of correspondences between upper mounting base and lower mounting base, be provided with support bar in relative mounting hole, the upper and lower end of support bar is connected with lower mounting base with upper mounting base by adjustable screw.
To improvement of the technical scheme: each mounting hole side of described upper mounting base and lower mounting base is respectively equipped with limiting plate, and limiting plate is provided with the hole corresponding with each mounting hole, and the limiting plate of upper mounting base and lower mounting base is mutually corresponding.
To further improvement in the technical proposal: described upper mounting base and lower mounting base are equilateral triangle, and mounting hole is arranged on the drift angle of mounting base and lower mounting base.
Beneficial effect:
Use surveying instrument adapter ring described in the utility model, by the adjustable screw on support bar, regulate the distance of upper and lower mounting base and then change height of instrument, can be widely used on the surveying instruments such as spirit-leveling instrument, transit.Upper fixed base plate is connected with the instrument base plate by pickup groove, lower fixed base plate can be connected by lower pickup groove (lower fixed base plate also can directly be placed in firmly observation platform on) with foot rest, the distance of adjusting surveying instrument and foot rest or measuring table by the adjustable screw of regulating on upper and lower fixed base plate, to meet the related request of national regulation, industry standard, can directly complete the thick of surveying instrument put down by the adjustable screw on base plate simultaneously.
The advantage of surveying instrument adapter ring described in the utility model, the one, avoid instrument foot rest opening degree excessive or too small, cause the instrument unstability and damage; The 2nd, meet the requirement that leveling norm is high to sight line, improve accuracy of observation; The 3rd, avoid the transit elevation angle or the angle of depression excessive, can't aim at and sight position, increase sighting mark error, reduce the problem of accuracy of observation; The 4th, reduce the website that turns of measuring route, reduce systematic error, improve measuring accuracy; The 5th, reduce working strength, increase work efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
