Abstract
The utility model relates to an angle horizon ruler, which comprises ruler base 1, a dial plate 4 and a pointer 3. The middle part of the ruler base 1 is provided with an arc-shaped breach 13, on which is provided with three arc-shaped grooves 8, 9, 10. A dial plate 3 having graduation 12 at both sides is installed in the middle arc-shaped groove 9, and a transparent guard board 7 is respectively arranged in the arc-shaped grooves 8, 10 arranged at both sides. A rotating shaft 6 is respectively supported in the bearing seats 5 of the two transparent guard boards 7. The two pointers 3 are fixed on the rotating shaft 6, and are positioned among the dial plate 4 and the two transparent guard boards. A protecting cover 2 is fixed on the ruler base 1 by the screw 14, and the transparent guard board 7 is shielded by part of both sides of the protecting cover. Both sides of the dial plate 4 are provided with graduation in 0-180 DEG. The unevenness of a plane can be measured accurately by the utility model, and the slope angle of the plane can also be measured.
Description
The utility model relates to measuring surveyor's staff, especially a kind of angle surveyor's staff.
In building and fitter's work, often need know the levelness of buildings or equipment.Measure levelness and generally be to use surveyor's staff.Normally used surveyor's staff can only be represented general horizontality, can not provide the concrete unevenness of buildings or equipment exactly, more can not angles of display.
The purpose of this utility model is the problem that can not show concrete unevenness and angle at present mean level chi, provides a kind of and can show the concrete unevenness numerical value of testee and the angle level meter of angle numerical value.
The utility model is achieved in that the angle surveyor's staff comprises rod support, index dial, rotating shaft, pointer and guard shield.Rod support is a flat rectangular parallelepiped.There is an arc notch at the rod support middle part.Be shaped on three deep-slotted chip breakers in the arc notch.In the deep-slotted chip breaker in the middle of index dial is installed in.Two transparent coversheet are installed in respectively in the deep-slotted chip breaker of index dial both sides.Be respectively equipped with bearing seat on two transparent coversheet.The rotating shaft two ends are installed in the bearing seat of two transparent coversheet.Two pointers that have counterweight are housed in the rotating shaft.Two pointers lay respectively between index dial and two transparent coversheet.The both sides of index dial all are shaped on the scale of 0-180 degree.Guard shield with the top of rod support arc notch and the local shutoff of two transparent coversheet by screw retention on rod support.
The tapered structure in rotating shaft two ends.
During use, the basal plane of rod support is leaned against on the plane of desire survey, because pointer is in the state vertical with surface level all the time under the counterweight effect, if tested plane is horizontal, the center position of pointed scale then, if tested plane is in obliquity, the center of the sensing off scale of pointer then, the angle that is departed from is the actual angle of inclination on tested plane.When measured surface is the lower surface of object, but the horizontality of the other end directing object lower surface of band counterweight pointer or the concrete angle that is tilted.
The utility model has the advantages that and to express the horizontality on tested plane definitely, can also read the angle of inclination on tested plane; But the upper face of Measuring Object not only also can be used for the lower surface of Measuring Object.
Fig. 1 is a front view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cut-open view of Fig. 1.
The utility model is described in further detail below in conjunction with accompanying drawing: the angle surveyor's staff comprises rod support 1, index dial 4, transparent coversheet 7, pointer 3 and guard shield 2.There is an arc notch 13 at the middle part of rod support 1.Be shaped on deep-slotted chip breaker 9 and deep-slotted chip breaker 8, deep-slotted chip breaker 10 on the arc notch 13.Index dial 4 is housed in the deep-slotted chip breaker 9.In deep-slotted chip breaker 8 and the deep-slotted chip breaker 10 transparent coversheet 7 is housed.The both sides of index dial 4 are shaped on the scale of 0-180 degree.On two transparent coversheet 7 bearing seat 5 is housed.The rotating shaft 6 that two ends are cone is contained in the diaxon bearing 5.Two pointers 3 that have counterweight 11 are fixed in the rotating shaft 6, and lay respectively between index dial 4 and two transparent coversheet 7.Guard shield 2 usefulness screws 14 are fixed on the rod support 1.Guard shield 2 is with the top of the arc notch 13 of rod support 1 and the local shutoff of two transparent coversheet 7.
Claims (2)
