Description

Technical Field

[0001] This utility model relates to the field of bases, and in particular to a rotating base. Background Technology

[0002] A laser level is a household hardware tool that uses a laser beam to replace manual readings. It measures the flatness of a surface or determines horizontal and vertical lines by emitting a laser beam.

[0003] In related technologies, a laser level includes a level body and a base, which are rotatably connected. When the point of impact of the laser beam is far from the laser level, it is difficult for workers to observe the location of the laser beam with the naked eye. In this case, the laser level needs to be used in conjunction with a laser detector. The laser detector is placed at the target location where the laser beam is ultimately intended to land. The level body emits a laser beam to the laser detector. The laser detector receives the laser beam emitted by the level body and detects whether there is a deflection in the incident angle. Then, the worker rotates the level body horizontally to calibrate the deflection of the incident angle, ensuring that the laser beam ultimately lands at the desired location.

[0004] Regarding the aforementioned technologies, the inventors believe that at least two workers are required to perform the above operations when calibrating the incident angle of the level body. One worker fixes the laser detector, and the other worker rotates the level body for calibration, which is a cumbersome operation. Utility Model Content

[0038] The implementation principle of a rotating base in this application embodiment is as follows:

[0039] The level body is placed on the rotating plate 2. When the laser detector detects the deflection angle of the level body, the laser detector sends the angle deflection signal to the circuit board 7 and controls the output shaft of the motor 31 to rotate at a suitable degree. The output shaft of the motor 31 drives the rubber roller 32 to rotate. Under the action of friction, the rubber roller 32 rotates and drives the mating wheel 33, which is in interference fit with the rubber roller 32, to rotate. The mating wheel 33 drives the inner ring edge 21, which is in interference fit with the second rubber ring 5, to rotate, thereby driving the rotating plate 2 to rotate, and thus driving the level body to automatically calibrate the angle.
