Background technology
Levelling pole is the scale that measurement of the level is used, formed by chi body and the measurement of the level graduation that is labeled on chi body, because its precision height directly affects the precision of measurement of the level, so existing levelling pole is all to adopt the materials such as on-deformable high-quality timber or fiberglass, aluminium alloy to make mostly, long stable to ensure chi, graduation is accurate.Traditional levelling pole has ruler, Sopwith staff and collapsible several, and structure and characteristics is separately as follows:
(1) ruler is integral structure, and therefore precision is higher, but length is grown (being generally 3 ~ 5 meters), conventionally needs configure dedicated car and room, carries with indoor storage etc. to meet field operation, makes survey crew feel inconvenience.
(2) Sopwith staff has retractility, and after shrinking, length is shorter is easy to carry, but after stretching, measurement graduation is accurate not, and accuracy of observation is low, therefore can only be used for the engineering surveys such as building operation, can not be used for professional high-precision leveling.
(3) utility model patent that China Patent No. is 201120148591.9, discloses a kind of folding leveling rod, and its blade is by all identical chi body hinged forming successively of length and shape, and chi face is detachable connection with blade.Although chi body can combine lengthening, be easy to carry, the precision micrometer adjustable device on chi surface zero basis is not but set, be also difficult to realize high precision.
Up to now, the high precision of levelling pole and portable formed contradiction fail to solve always.
Summary of the invention
The utility model is in order to solve the existing above-mentioned technical matters of prior art, provides one to be not only easy to carry but also have high-precision adjustable for height high-precision leveling scale.
Technical solution of the present utility model is: a kind of adjustable for height high-precision leveling scale, there is the chi band of measurement of the level graduation to form by chi body and mark, described chi body is joined and is formed by web member by many pile foundations chi body, it is characterized in that: the upper end of described chi body and chi head join, the lower end of described chi body with in have the base of cavity to join; Described chi band upper end joins by elastic force apparatus and chi head, described chi band lower end be placed in chi band fixed head moving up and down in base and join, between chi band fixed head and the base plate of base, be provided with the regulating part of capable of regulating chi band fixed head and the upper and lower relative position of base plate, the basis point line that is provided with graduation docking window and is fixed on docking window side on base, on described chi band, be also provided with the graduation butted line that can be positioned at docking window place, the wire diameter of described basis point line and graduation butted line is all less than 0.2mm.
Described regulating part is nut, and nut two ends are connected with the second bolt thread that is fixed on the first bolt on chi band fixed head and be fixed on base plate respectively, and the screw thread rotation opposite direction of the first bolt and the second bolt is provided with nut and regulates window on described base.
The utility model can connect into the base water object staff body of portable many 1 ~ 2 meter the levelling pole body of an overlength, chi band can be fixed on chi body by chi head and base, dock the docking facilitiess such as window by graduation, the overlength levelling pole that makes combination measure aspect Reticle accuracy and reliability all identical with ruler, not only be easy to carry but also there is high precision, solved the existing problem of prior art, improved measurement of the level work efficiency, reduced measurement cost.
