Abstract

The utility model discloses a levelling instrument. The levelling instrument comprises an instrument body, the cross section of the instrument body is square; the instrument body comprises two working faces parallel mutually, namely a front side and a back side; a level indication device is arranged on the front side and comprises transparent indication panels fixed on the front side, and parts of the instrument which correspond to the panels are hollow; cross reticles are arranged on the indication panels, and one reticle is parallel to one side of the front side of the instrument body; axes extending inside the instrument body are arranged on the indication panels, perpendicular to the front side, and concentric with the cross reticles; and pointers are movably connected with the axes. The working faces are placed on the to-be-measured surface during measurement, all that is needed is to observe whether the pointers align with the cross reticles, so that the to-be-measured surface is horizontal or vertical or not is obtained; meanwhile, due to gravitation, the positioning of the pointers is quick, and the operation requires less labor.

Description

A kind of surveyor's staff

Technical field

The utility model relates to a kind of surveyor's staff.

Background technology

Need the usage level chi to measure in occasions such as building, machinery installation, carpenters.Existing level chi chi body is processed by the aluminium section of hollow usually, and integral body is flat strip, on open circular hole or slot, settle circular bubble seat in the hole, in the bubble seat air level is arranged, the chi end of body is provided with plastic end cover.When needing to measure a surface level; Be placed on surveyor's staff on measured, the bubble position in the range estimation air level is if bubble is in air level horizontal center position; This measured level then; But the air level locating speed also is difficult for accurately confirming its position slowly, and when carrying out the measurement of levelness, verticality and degree of tilt simultaneously, surveyor's staff must be installed three air levels and could measure simultaneously.

Summary of the invention

The technical matters that the utility model will solve provides the fast surveyor's staff of a kind of locating speed.

For solving the problems of the technologies described above, the utility model comprises that xsect is square chi body, and the chi body comprises two workplaces that are parallel to each other, front and back; The front is provided with the level indicating device; Its design feature is that said level indicating device comprises transparent indication panel, and indication panel is fixed on the front, chi body corresponding position hollow; On indication panel, be provided with the cross groove, a groove wherein is parallel with the one side in chi body front; Indication panel is provided with the axle of in the chi body, stretching, and axle is perpendicular to positive and concentric with the cross groove; On axle, be connected with pointer.

After adopting said structure, when measuring, workplace is placed on measured, only needs to observe pointer and whether align, can learn whether level or vertical of measured face with the cross groove, and because action of gravity pointer location is fast, rapid operation.

Said chi body hollow and its xsect are rectangular, in light weight and convenient the making and use.

The equal angular groove that is provided with on the said indication panel, another face at angle of inclination such as also can be made in the angle of inclination that can record the face of surveying during measurement, thereby the convenient adjusting range of grasping.

The front and back of said chi body is arranged with indication panel, uses more convenient.

The axis of said pointer is provided with the pointer groove, is easy to observation.

Said level indicating device has two, and it is provided with along chi body length direction is corresponding at interval, can improve the degree of accuracy of measurement.

Two grooves of said cross groove extend to chi body two ends respectively, convenient observation.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain:

Fig. 1 is the structural representation of the utility model;

The synoptic diagram that Fig. 2 analyses and observe along the A-A line for Fig. 1.

Embodiment

Can know that by Fig. 1 and Fig. 2 surveyor's staff comprises that xsect is the chi body of rectangle, chi body both ends open and be flat strip.The chi body comprises two workplaces that are parallel to each other 1, front 2 and the back side 3.Chi body positive 2 is provided with the level indicating device, and the level indicating device comprises transparent circular indication panel 4 and pointer 7, and indication panel 4 is fixed on chi body positive 2; Chi body corresponding position hollow; For convenient observation pointer 7 points to, also can be symmetrical set indication panel 4 with the back side 3 in the front 2 of chi body, make and reduction surveyor's staff weight for convenient; Whole hollow outs and use the chi body of high-intensity transparent material production technique chi in the middle of the surveyor's staff also can use aluminum alloy flat tube as the chi body.On indication panel 4, be provided with cross groove 8; Cross groove 8 comprises horizontal groove 81 and vertical groove 82, and wherein vertical groove 82 is parallel with positive 2 long limit, and vertical groove 82 extends to chi body two ends respectively with horizontal groove 81; While equal angular groove that is provided with on indication panel 4; Can record the angle of inclination of the face of surveying during measurement, thereby the convenient adjusting range of grasping such as also can make at another face at angle of inclination; At the center of two indication panels 4 axle 5 is set, the two ends of axle 5 are installed in respectively on the indication panel 4, so just make axle 5 perpendicular to indication panel 4 and concentric with cross groove 8; Be connected with pointer 7 in axle 5 intermediate active, pointer 7 is fixing through on axle 5, installing axle sleeve 6 additional, and pointer 7 can rotate freely around axle 5 like this.Sensing for convenient observation pointer 7 is provided with pointer groove 9 on the axis of pointer 7.Be symmetrical set the level indicating device at the two ends of surveyor's staff, not only can improve the degree of accuracy of measurement, also can be used for measuring two faces that span is arranged.

Workplace 1 with surveyor's staff during use is placed on measured; Because action of gravity, pointer 7 meeting natures are sagging, and are very fast with respect to the air level locating speed; Can learn whether level or vertical of measured face this moment through observing the sensing of pointer 7 on indication panel 4; Or read measured angle of inclination through the groove of indication panel 4, thereby the convenient adjusting range of grasping such as also can make at another face at angle of inclination.Whether when measurement has two faces of span, the two ends of surveyor's staff are placed on two faces, treat that pointer 7 is stable, it is identical to observe two pointers 7 point to, and can learn whether level or vertical of two sides.
