Description

Adjustable for height high-precision leveling scale
Technical field
The invention belongs to field of measuring technique, relate in particular to a kind of being not only easy to carry but also there is high-precision adjustable for height high-precision leveling scale.
Background technology
Levelling pole is the scale that measurement of the level is used, by chi body and the measurement of the level graduation that is labeled on chi body, formed, because its precision just 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 guarantee 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, so precision is higher, but length is grown (being generally 3 ~ 5 meters), conventionally needs configure dedicated car and room, to meet field operation, carries with indoor storage etc., makes survey crew feel inconvenience.
(2) Sopwith staff has retractility, and after shrinking, length is shorter is easy to carry, but it is accurate not after stretching, to measure graduation, and accuracy of observation is low, thus can only be for engineering surveys such as building operation, can not be 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 equal identical chi body hinged the 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 present invention is in order to solve the existing above-mentioned technical matters of prior art, provides a kind of and is not only easy to carry but also have high-precision adjustable for height high-precision leveling scale.
Technical solution of the present invention is: a kind of adjustable for height high-precision leveling scale, by chi body and mark, there is the chi band of measurement of the level graduation to form, 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 present invention can connect into the base water object staff body of portable many 1 ~ 2 meter the levelling pole body of an overlength, by chi head and base, chi band can be fixed on chi body, by graduation, dock the docking facilitiess such as window, 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.

Embodiment
Embodiment 1:
As shown in Fig. 1,2,3,4,5: same as the prior art, by chi body 1 and mark, there is the chi band 2 of measurement of the level graduation to form, described chi body 1 is joined and is formed by web member 3 by many pile foundations chi body, the length of every pile foundation chi body can be 1 ~ 2 meter, web member 3 can be the various structures such as hinge, bolt, sleeve, but should guarantee that many pile foundations chi body both can be connected to a ruler, can fold or dismantle again.The upper end and the chi head 4 that are chi body 1 with prior art difference join, the lower end of chi body 1 with in have the base 5 of cavity to join, both can be structure as a whole, also can join by securing member (bolt etc.); Chi band 2 upper ends are by elastic force apparatus 6(spring) articulate mutually with chi head 4, chi band 2 lower ends be placed in base 5 and chi band fixed head 7 moving up and down articulates, between chi band fixed head 7 and the base plate of base 5, be provided with the regulating part 8 of capable of regulating chi band fixed head 7 and the upper and lower relative position of base plate, the basis point line 10 that is provided with graduation docking window 9 and is fixed on docking window 9 sides on base 5, basis point line 10 is constant with the distance of the base plate of base 5, for example, can be taken as 10cm or 20cm.On chi band 2, be also provided with the graduation butted line 11 that can be positioned at docking window 9 places, the wire diameter of described basis point line 10 and graduation butted line 11 is all less than 0.2mm.Regulating part 8 also can be various structures, as long as can adjustable ruler band fixed head 7 and the upper and lower relative position of base plate.The regulating part 8 of the embodiment of the present invention is nut, nut two ends are threaded with the second bolt 13 that is fixed on the first bolt 12 on chi band fixed head 7 and be fixed on base plate respectively, the screw thread rotation opposite direction of the first bolt 12 and the second bolt 13 is provided with nut and regulates window 14 on described base 5.
During use, by web member 3, many pile foundations chi body is connected to a ruler for chi body 1, again by chi body 1 and chi head 4, base 5 joins, chi band 2 is articulated in respectively on chi head 4 and chi band fixed head 7, by nut, regulate window 14 setting nuts to adjust the distance between chi band fixed head 7 and the base plate of base 5, make graduation butted line 11 and basis point 10 conllinear of ruling, because the wire diameter of basis point line and graduation butted line is all less than 0.2mm, thereby can guarantee measurement of the level graduation on chi band 2 and accurate dockings of basis point line 10 on chi body base 5, can form from chi body base 5 base plates upwards, the integrated levelling pole that graduation is continuous, can be used for high-precision measurement of the level.Finish using, chi band 2 can be taken off, simultaneously by regulating securing member to make chi head 4, rod support 5 separated with chi body 1, then by web member 3, chi body 1 is folding or split into basic chi body, be easy to carry and preserve.
Embodiment 2:
As shown in Figure 6,7: basic structure is with embodiment 1, with embodiment 1 difference be that elastic force apparatus 6 is that existing spring wind tape removes chi bar structure, chi band of the present invention 2 upper ends are joined with it and form spring wind tape, elastic force apparatus 6 is placed in the tape measure draw-in groove 15 being fixed on chi head 4, the lower end of chi band 2 and chi band fixed head 7 join.
Use procedure is substantially the same manner as Example 1.
