Abstract
The utility model relates to the technical field of a tool and a measuring tool, particularly a rotary leveling bubble for a level. The utility model aims at the problems that when a rotary leveling bubble arranged on the existing level is used, a double face can not be seen, and a basic angle of the leveling bubble can not be adjusted. The rotary leveling bubble for the level with the visual double face and the adjustable basic angle is provided. The utility model comprises a rotary table A, a rotary table B, an eccentric leveling bubble, a dial and rotary table bases, and has the technical proposal that the eccentric leveling bubble is fixed on the rotary table B, and the dial is fixed on the rotary table A. The rotary table A and the rotary table B are installed on the rotary table bases, and external teeth of the same number of teeth and modulus are arranged on the rotary table A and the rotary table B. The external teeth arranged on the rotary table A are engaged with the external teeth arranged on the rotary table B, and a pair of gear transmission pairs is formed. When the utility model is installed on the level, the rotary table bases which are provided with the rotary table A and the rotary table B are fixed on the level, and the ruler is connected together with a hinge of the level through a pin shaft arranged on the rotary table A.
Description
Technical field
The utility model relates to the measuring tool technical field, particularly a kind of rotary level bubble that is used on the surveyor's staff.
Background technology
The rotary level bubble that is contained on the surveyor's staff is to be used to measure the surveyor's staff parts that the object tilt angle of certain angle is arranged with surface level, the rotary level bubble of using on the existing surveyor's staff is to adopt single turntable structure form, and in use it exists the weak point that rotary level bubble is can not be two-sided visual, air level benchmark angle can not be transferred and structural strength is low.
Summary of the invention
The utility model is in use existing can not be two-sided visual, air level benchmark angle can not be transferred and structural strength the is low weak point of the rotary level bubble of using on the existing surveyor's staff, provide a kind of two-sided visual, benchmark adjustable angle and structural strength high be used for rotary level bubble on the surveyor's staff.
The technical solution adopted in the utility model is finished in the following way: the rotary level bubble that is used on the surveyor's staff comprises rotating disk A, rotating disk B, eccentric air level, index dial and rotary disk basement.Its main points are: eccentric air level is fixed on the rotating disk B, index dial is fixed on the rotating disk A, and rotating disk A and rotating disk B are installed on the rotary disk basement, and rotating disk A and rotating disk B are provided with the external tooth of the identical number of teeth and modulus, external tooth on the rotating disk A is meshed with external tooth on the rotating disk B, and they are a pair of gear driving pairs.
When being installed in the utility model on the surveyor's staff, the rotary disk basement that rotating disk A and rotating disk B are housed is fixed on the surveyor's staff, ruler links together by bearing pin and the surveyor's staff hinge that is located at rotating disk A.
During use, when the ruler of rotational fixation on rotating disk A, rotating disk A rotates with ruler, driving rotating disk B by gear drive again rotates, thereby driving the eccentric air level that is fixed on the rotating disk B rotates, owing to be provided with the external tooth of the identical number of teeth and modulus on rotating disk A and rotating disk B, so the angle that the angle of eccentric air level rotation and ruler turn over is equal, and the angle that ruler and eccentric air level turn over can reflect on the index dial that is fixed on the rotating disk A intuitively.Owing to adopted eccentric air level on rotating disk B, thereby when having guaranteed that angle between surveyor's staff and the ruler is zero, bubble is in horizontality with respect to the surveyor's staff basal plane.
The rotary level bubble that the utility model is used for using on rotary level bubble and the existing surveyor's staff on the surveyor's staff is compared, and has two-sided visual, benchmark adjustable angle and the high characteristics of structural strength.
