Abstract
The utility model discloses a box staff with a leveling bubble and aims at providing a box staff with a leveling bubble, which has a simple structure, is convenient to observe and operate, and improves the measuring precision and measuring speed. The box staff comprises a box staff main body (1), wherein scale marks are formed on the front surface of the box staff main body (1); and the leveling bubble (2) is further formed on the box staff main body (1). When the box staff is used for measuring, the staff can judge whether the box staff main body (1) is vertical to the ground plane through the leveling bubble (2) and can quickly straighten the box staff main body (1) for carrying out leveling operation. The box staff with the leveling bubble is applied to the leveling field.
Description
Technical field
The utility model relates to a kind of Sopwith staff with leveling bubble.
Background technology
In numerous engineering surveys, usually bound measurement of the level, and often use Sopwith staff as survey instrument for levelling practice person.Existing Sopwith staff, calibration instrument is not set, whether the placement level of Sopwith staff leans on staff's experience fully, this is for the people who lacks the measurement of the level experience, Sopwith staff both had been difficult for holding up the straight state that also is difficult for after maintenance is held up directly, and majority all will lean on master of ceremonies person's commander could hold up as much as possible straight Sopwith staff.Will cause like this measurement of the level to produce larger measuring error, affect the precision of measurement of the level, also increase observation time, inefficiency simultaneously.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, Sopwith staff with leveling bubble of being convenient to observe and operate, improve measuring accuracy and measuring speed is provided.
The technical scheme that the utility model adopts is: the utility model comprises the Sopwith staff main body, and the front of described Sopwith staff main body is provided with scale mark, also is provided with leveling bubble on the described Sopwith staff main body.
Preferably, the sidepiece of described Sopwith staff main body is provided with web joint, and described leveling bubble is arranged on the sidepiece of described Sopwith staff main body by described web joint.
Preferably, described leveling bubble is arranged on the upper end of described Sopwith staff main body.
The beneficial effects of the utility model are: because the utility model comprises the Sopwith staff main body, the front of described Sopwith staff main body is provided with scale mark, and described Sopwith staff main body is provided with leveling bubble; So when measuring, the staff can judge whether described Sopwith staff main body is vertical with ground level by described leveling bubble, and hold up fast straight described Sopwith staff main body, cooperate master of ceremonies person to finish together measurement, generally speaking, use the utility model, can Effective Raise measuring accuracy and measuring speed.

Fig. 2 is structural representation of the present utility model (side);
Fig. 3 is structural representation of the present utility model (overlooking).
Embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, the utility model relates to a kind of Sopwith staff of measurement of the level, and is simple in structure, processing ease.It comprises Sopwith staff main body 1, the front of described Sopwith staff main body 1 is provided with scale mark, described Sopwith staff main body 1 is provided with leveling bubble 2, described Sopwith staff master's 1 sidepiece is provided with web joint 3, the upper and lower end of described web joint 3 adopts connecting screw to be fixed on the described Sopwith staff main body 1, and described leveling bubble 2 is arranged on the sidepiece of described Sopwith staff main body 1 by described web joint 3.Watch easily described leveling bubble 2 for the ease of the staff who holds up chi, usually described leveling bubble 2 is arranged on the upper end of described Sopwith staff main body 1, if the height overall of described Sopwith staff main body 1/length is 1.2 meters, so just described leveling bubble 2 is arranged between 1.0 meters～1.1 meters.In use, hold up the staff of chi gently to hold described Sopwith staff main body 1, keep the bottom of described Sopwith staff main body 1 motionless, then swing gently described Sopwith staff main body 1 all around, until the bubble in the described leveling bubble 2 is placed in the middle, show that described Sopwith staff main body 1 is perpendicular with ground level, at this moment just can carry out accurate reading.
The utility model is compared with the Sopwith staff that described leveling bubble 2 was not set originally, and the precision of measurement of the level and measuring speed have all obtained improving greatly this, and therefore, the utility model is widely used in the measurement of the level field.
