For example, when a first gear fixed to the first rotating shaft and a second gear fixed to the second rotating shaft are directly engaged, the rotation directions of the second rotating shaft and the first rotating shaft may be opposite. The person skilled in the art can also realize the linkage of the first rotating shaft and the second rotating shaft through a transmission chain, a belt and a rod, which are not described in detail herein.

It should be noted that the term "the first rotating shaft rotates" in this document refers to the first rotating shaft rotating relative to the reference base, and "the angle of the first rotating shaft rotating" refers to the angle of the first rotating shaft rotating relative to the reference base, that is, it includes the case where the first rotating shaft is stationary relative to the ground and the reference base moves relative to the ground, for example, the first rotating shaft is stationary relative to the ground and the reference base rotates at an inclination angle of α relative to the ground, and the angle of the first rotating shaft rotating is- α.

Similarly, the term "the second rotating shaft rotates" as used herein means that the second rotating shaft rotates relative to the reference base, and "the angle of rotation of the second rotating shaft" means that the second rotating shaft rotates relative to the reference base, that is, it includes the case where the reference base moves relative to the ground and the second rotating shaft moves further relative to the ground, for example, the reference base rotates at an inclination angle of α relative to the ground, and the angle of rotation of the second rotating shaft relative to the ground is β ═ α + γ, and then the angle of rotation of the second rotating shaft is γ.

In the present application, "first" and "second" are used only for distinguishing different members, and have no special meaning other than the technical features of the members in the present application.

Fig. 2 is a schematic view of an embodiment of the present invention in which the transmission mechanism is a cam.

In the embodiment shown in fig. 2, an embodiment of a leveling measuring device is provided, which comprises a reference base 1, a plumb 2, a first rotating shaft 3, a second rotating shaft 4, a bearing plate 5 and a level gauge 6. The lower surface 9 of the reference base is a reference plane. The transmission mechanism comprises a cam 8 fixed on the first rotating shaft 3, and when the first rotating shaft rotates, the level gauge is pushed to rotate around the second rotating shaft through the cam.

One typical profile version of the cam structure shown in fig. 2 is a standard elliptical cam. The first rotating shaft is a vertical driving shaft, a cam structure is arranged in the middle of the first rotating shaft, and the cam structure and the vertical driving shaft are relatively fixed.

Preferably, the transmission mechanism further comprises a push rod 7, one end of the push rod is contacted with the cam, and the other end of the push rod is contacted with the level gauge. The cam structure and the driven push rod form a movable follower disc cam mechanism, and the installation mode is eccentric installation. For example, when the level is installed on the upper surface of the reference base, the rod body of the push rod passes through the vertical hole on the reference base and moves in one dimension relative to the reference base. The upper end of the driven push rod and the level carrier plate adopt a point contact mode.

In any of the embodiments of the present application, preferably, the centre of gravity of the level is offset from the second axis of rotation. Further, when the level is secured to the carrier plate, the level and the carrier plate form a level assembly, the center of gravity of the carrier plate or the level assembly being offset from the second axis of rotation.

For example, in any of the embodiments of FIGS. 3-4, the center of gravity of the level (or level assembly) is offset from the second axis of rotation.

The spirit level carrier plate is installed in the second pivot, and the second pivot is the driven shaft, and when the motion of driven push rod transmission plumb driving shaft, promotion spirit level carrier plate rotated around the axle center of second pivot.

Fig. 3 is a schematic view of an embodiment in which the first rotating shaft is located below the second rotating shaft.

The first rotating shaft is positioned below the second rotating shaft, when the first rotating shaft rotates, the transmission mechanism pushes the lower surface of the level gauge to overcome the gravity center, and the action point of force moves upwards around the second rotating shaft. For example, in fig. 3, the center of gravity is to the left of the second axis of rotation, and the point of action of the lower surface of the drive mechanism and the level (or level assembly) is to the left of the second axis of rotation.

Fig. 4 is a schematic diagram of an embodiment in which the first rotating shaft is located above the second rotating shaft.

The first rotating shaft is positioned above the second rotating shaft, when the first rotating shaft rotates, the transmission mechanism pushes the upper surface of the level gauge to overcome the gravity center, and the force action point moves downwards around the second rotating shaft. For example, in fig. 4, the center of gravity is to the left of the second axis of rotation and the point of action of the transmission mechanism and the upper surface force of the level (or level assembly) is to the right of the second axis of rotation.

Preferably, in the embodiment of FIGS. 3-4, the level (or level assembly) includes a first locating member and the datum base includes a second locating member; when the reference plane is horizontal, the first positioning component and the second positioning component are contacted, so that the level gauge is in a horizontal state.

Fig. 3 to 4 are front views of the device in an initial state, a first positioning surface 11 on the level carrier plate 5 and a second positioning surface 12 on the reference base 1 are fitting surfaces, and when the first positioning surface contacts with the second positioning surface, a response upper surface of the level carrier plate 5 is in a horizontal state, which can provide reference for installation and calibration of the horizontal adjustment mechanism.

The center of the level assembly is offset to one side of the first and second positioning members relative to the second axis of rotation. For example, when the level carrier plate is designed to be eccentric, the center of gravity of the level carrier plate is deviated to one side of the positioning surface relative to the rotating shaft mounting hole on the level carrier plate.

FIG. 5 is a schematic view of the external structure of the measuring device of the present invention including a bubble level.

It should be noted that, in any of the embodiments of the present application, preferably, the level is in the form of a bubble. The bubble level is still widely applied to horizontal adjustment of a structure with general precision requirements at present, but has the defect of poor operation stability of bubbles, and when an adjusted plane is close to the horizontal plane, the bubbles are severely changed along with the angle of the measured or adjusted plane, so that the stability is poor.

In this embodiment, the bubble level is mounted on the upper surface of the level carrier plate. When the level carrier plate receives the motion transmitted by the driven push rod, the upper surface inclines, and the inclined angle can be read or calculated by the bubble level.

The main functional components of the horizontal adjusting mechanism comprise: the device comprises a reference base 1, a vertical driving shaft (namely a first rotating shaft) 3, a vertical structure 2, a cam structure (not shown in the figure), a driven push rod (not shown in the figure), a level driven shaft (namely a second rotating shaft) 4, a level bearing plate 5, a bubble level 6 and the like.

The vertical driving shaft and the level driven shaft are both arranged on the reference base, wherein the vertical driving shaft is a rotating shaft, and the level driven shaft is a mandrel. By adopting a proper shafting structure, the plumb driving shaft can rotate around the axis of the plumb driving shaft, and the upper structure of the driven shaft of the level can rotate around the axis of the level.

The vertical structure is arranged on one side of the vertical driving shaft and is suspended outside the reference base, and when the reference base inclines, the vertical driving shaft rotates around the reference base by taking the gravity of the vertical structure as input power.

The vertical structure has a weight ratio large enough for the cam structure mounted on the level carrier plate, the bubble level, the driven push rod and the vertical driving shaft to control the deviation angle error caused by the weight of the level carrier plate, the bubble level, the driven push rod and the cam structure within the precision required range.

Fig. 6 is a schematic view of a level adjustment function in a state of use in the present invention.

The horizontal adjusting mechanism is placed on a plane to be adjusted, a reference surface 9 of the horizontal adjusting mechanism is in contact with a plane 10 to be adjusted, when a horizontal angle error α exists in the plane 10 to be adjusted, the reference surface 9 generates an inclination angle α relative to the horizontal plane along with the plane 10 to be adjusted, the vertical structure 2 drives the vertical driving shaft 3 to generate a rotation angle theta relative to the reference base 1, and the rotation angle theta is equal to the inclination angle α.

The plumb driving shaft 3 drives the cam structure 8 rotation angle theta installed on it, the cam structure 8 promotes the driven push rod 7 rather than the point contact, the driven push rod 7 carries out one-dimensional translation motion for benchmark base 1 to promote surveyor's level carrier plate 8, surveyor's level carrier plate 8 rotates around surveyor's level driven shaft 4, make the surveyor's level carrier plate respond that the inclination β of upper surface for the horizontal plane is greater than by regulation surface inclination α through designing suitable cam profile, can realize inclination β enlargies the inclination α different degree.

FIG. 7 is a graph of the tuning effect of the embodiment of the present invention.

The inclination angle β corresponds to the inclination angle α, and the inclination angle β has an enlarged relationship with the inclination angle α during the use of the transmission mechanism (such as a cam).

When the device of this application is used, the level adjustment appearance is placed on waiting to adjust the plane, and the benchmark base takes place to incline along with waiting to adjust the plane. The vertical driving shaft rotates around the axis of the vertical driving shaft under the action of the gravity of the vertical structure, and generates an inclination angle relative to the reference base, wherein the size of the inclination angle is equal to the levelness deviation of a plane to be adjusted. The rotation quantity of the vertical driving shaft is transmitted to the level carrier plate through the transmission mechanism, and is added to the deflection angle of the level carrier plate as a gain quantity, and finally reflected on the reading of the level. The process realizes that the rotation angle of the level gauge bearing plate is larger than that of the vertical driving shaft, namely, the amplification of the inclination angle of the plane to be adjusted is realized. By designing the scale of the drive mechanism (e.g. by the theoretical profile of the cam structure), the degree of magnification of the tilt angle can be controlled, thereby improving the sensitivity of the level during leveling.
