Description
Technical field
The present invention relates to field of measuring technique, specifically refer to a kind of triangle level meter.
Background technology
In the processes such as check of the manufacturing, mounting equipment, product, conventionally need level meter to check the horizontal situation of plane, conventional level meter has frame level and long leveling ruler formula level meter at present.When measuring, level meter is directly put in tested plane, because the bottom of level meter is that a plane and tested plane are that face and face contact measurement precision are not high, and level meter once can only be measured tested plane level whether in one direction, if want to measure tested plane level whether in another direction, need the direction that changes level meter to measure separately, measure so cumbersome.
For solving the problems of the technologies described above, application number is that 201120037603.0 patent discloses a kind of Multi-way gradienters, this patent mainly also can only be measured by the both direction of side plane by the level meter of two long leveling ruler formulas is hinged simultaneously, and the length of level meter of the prior art is all changeless, level meter is when measurement diameter is than the little plane of the diameter of level meter like this, because the part of level meter does not reach tested plane, measurement inaccurate; Level meter is when measurement diameter is than the large plane of the diameter of level meter, because level meter is too little, to repeatedly measure such measurement result cumbersome and that measure also inaccurate, therefore the level meter of certain length can only be measured the plane within the scope of certain diameter, plane is too large or too littlely all cannot measure, and measurement range is smaller.
Summary of the invention
The technical problem to be solved in the present invention is: overcome above existing defect, a kind of triangle level meter that a kind of measuring accuracy is high, measurement range is large is provided.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of triangle level meter, comprise rotating shaft, be arranged on the circular spirit-leveling instrument at rotating shaft top, surveyor's staff, one end of described surveyor's staff is connected with bearing, bearing holder (housing, cover) is contained in rotating shaft, described surveyor's staff is provided with elongated hole, the cradling piece that can slide on elongated hole is installed in elongated hole, described cradling piece is provided with nut in the contact position of the upper surface with surveyor's staff, the number of described surveyor's staff is 3 and by bearing holder (housing, cover), is contained in rotating shaft successively from top to bottom, in the bottom of rotating shaft, be provided with the shaft nut for preventing that bearing from falling down, the bottom of three described cradling pieces is in same level and lower than the k level of rotating shaft.
The present invention's advantage is compared with prior art: level meter of the present invention is three cradling pieces and tested plane contact, point is high with face contact measurement precision, and can measure the horizontal situation of tested plane in three directions simultaneously, three cradling pieces all can rotate around the axis, be convenient for measuring like this any direction of tested plane, cradling piece can slide on surveyor's staff, and user can regulate the position of cradling piece on surveyor's staff according to the demand of oneself like this, and measurement range is large.
As improvement, described cradling piece is provided with boss in the lower surface contact position with surveyor's staff, and arranging of boss facilitates the installation of cradling piece on surveyor's staff also to facilitate the slip of cradling piece on surveyor's staff.
As improvement, the structure of the bottom of described cradling piece is conical structure, and point is high with face contact measurement precision.
As improvement, the both sides of the elongated hole on described long leveling ruler are provided with rule, and arranging of rule facilitates the position of accurate adjustment cradling piece on surveyor's staff.
As improvement, the dial plate of described circular spirit-leveling instrument is provided with the convenient a plurality of limbus lines how many diameters of bubble offsetting increase successively of observing, and observes like this bubble ratio more accurate.
As improvement, described surveyor's staff and cradling piece are all made by hard material, and hard material is not easy to wear, and service time for a long time and more stable.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
By reference to the accompanying drawings, a kind of triangle level meter, comprise rotating shaft 1, be arranged on the circular spirit-leveling instrument 2 at rotating shaft 1 top, surveyor's staff 3, one end of described surveyor's staff 3 is connected with bearing 4, bearing 4 is sleeved in rotating shaft 1, described surveyor's staff 3 is provided with elongated hole 5, the cradling piece 6 that can slide on elongated hole 5 is installed in elongated hole 5, described cradling piece 6 is provided with nut 7 in the contact position of the upper surface with surveyor's staff 3, the number of described surveyor's staff 3 is 3 and by bearing 4, is sleeved in rotating shaft 1 successively from top to bottom, in the bottom of rotating shaft 1, be provided with the shaft nut 8 for preventing that bearing 4 from falling down, the bottom of three described cradling pieces 6 is in same level and lower than the k level of rotating shaft 1.
