Description

Technical Field

[0001] The present invention relates to the field of measurement technology, and particularly to an integrated spirit level integrating an electronic spirit level and a physical spirit level. Background Art

[0002] A spirit level (or a bubble level) is an auxiliary measurement device, commonly used in various optoelectronic instruments such as theodolites, levels, compasses, electronic scales, total stations, etc. It mainly includes a physical spirit level observed by the naked eye and an electronic spirit level that is digitally displayed after optoelectronic detection. During the measurement process, whether the device is in a horizontal position is crucial for accurate measurement. If adjusted manually, on the one hand, it is difficult to operate with low accuracy, and on the other hand, if there is displacement during use and the customer fails to detect it in time, it will also affect the measurement result. Therefore, an electronic spirit level is needed to monitor and remind at all times. However, the electronic spirit level and the physical spirit level installed in the device are separated, which brings two defects: 1. It is troublesome to install and disassemble, increasing the manufacturing cost. 2. It is not easy to ensure the consistency between the electronic spirit level and the physical spirit level.

[0003] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

Detailed Embodiment

[0022] The following combines the drawings to describe in detail the specific embodiments of the present invention. However, it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0023] Unless otherwise clearly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "having" etc. will be understood to include the stated elements or components, without excluding other elements or other components.

[0024] As Figures 1 to 4 shown, the spirit level 100 in the preferred embodiment of the present invention integrates a physical spirit level and an electronic spirit level. Therefore, it integrates two modes of visual observation and electronic monitoring, with stronger functionality.

[0025] Specifically, the spirit level 100 integrates the first base 10 and the second base 20 into an integrated base, which are respectively used to install the physical spirit level and the electronic spirit level. The first base 10 has a first mounting cavity 11, in which a support seat 41 for supporting the physical spirit level is provided. The top of the support seat 41 adopts a concave design, and a circular fourth step portion 413 is provided at the opening for supporting the physical spirit level. Such a design can also reduce the overall weight.

[0026] Preferably, the physical spirit level part is provided with an attitude fine-tuning function for adjusting the inclination angle of the physical spirit level to match and synchronize with the electronic spirit level. This attitude fine-tuning function is mainly realized by an arc-shaped protrusion 411 protruding from the bottom of the support base 41, an arc-shaped support groove 12 recessed in the bottom of the first installation cavity 11, and a plurality of adjusting screws 43. A first positioning hole 14 communicating with the first installation cavity 11 is opened at the bottom of the first base 10, and a second positioning hole 412 is opened at the corresponding position at the bottom of the support base 41. The adjusting screw 43 passes through the first positioning hole 14 and is fixed in the second positioning hole 412. The arc-shaped protrusion 411 at the bottom of the support base 41 is recessed in the arc-shaped support groove 12, and its diameter is slightly smaller than the inner diameter of the first installation cavity 11. Therefore, the support base 41 will shake without other supporting effects, and the attitude fine-tuning and fixing are carried out by adding the adjusting screw 43. A meshing thread section is provided between the adjusting screw 43 and the second positioning hole 412, and the size of the part of the adjusting screw 43 exposed at the bottom of the first base 10 for operation is relatively large. Therefore, the attitude of the support base 41 can be fine-tuned by rotating the adjusting screw 43, and then the inclination angle of the physical spirit level at the top can be adjusted to match the electronic spirit level and avoid errors. Preferably, three first positioning holes 14 are opened, forming an equilateral triangle. Of course, the specific number can be designed according to the accuracy requirements and the size of the equipment, and this embodiment does not limit it.

[0027] Of course, the positions of the arc-shaped protrusion 411 and the arc-shaped support groove 12 can be swapped, that is, the arc-shaped protrusion 411 is formed at the bottom of the first installation cavity 11, and the arc-shaped support groove 12 is opened at the bottom of the support base 41. This embodiment does not limit it.

[0028] Furthermore, a bearing can be installed between the adjusting screw 43 and the first positioning hole 14 to give the adjusting screw 43 an axial supporting force, avoiding axial movement due to loss of support during rotation and resulting in the failure of fine-tuning.

[0029] In this embodiment, the first base 10, the first installation cavity 11, the support base 41, etc. are all cylindrical. Therefore, the physical spirit level is a disc-shaped second liquid storage box 42, which at least has a transparent visualization area on one end surface. The position of the internal bubble can be observed through this area. Of course, a second liquid storage box 42 that is entirely transparent can also be selected, with higher flexibility. A circular scale line is provided in the central area of the second liquid storage box 42 for judging the levelness of the installation surface, and its diameter can be set according to the accuracy requirements. This embodiment does not limit it.

[0030] Since the second liquid storage box 42 is detachably fixed to the support base 41, it can be quickly replaced and paired when the second liquid storage box 42 is damaged or needs to be replaced for other reasons, with relatively high flexibility. It is easy to think that the support base 41 is also detachably fixed to the first installation cavity 11. Therefore, when replacing physical spirit levels of different sizes or shapes, the support base 41 with different step portions can be correspondingly replaced, further improving flexibility.

[0031] For the electronic spirit level part, it mainly includes a photosensitive component and a light-emitting component arranged up and down, and a first liquid storage box 34 arranged between the two. The three form an angle voltage conversion module. Due to the presence of the middle air bubble, the light intensity of the projection at the position of the air bubble is different from that of the light not projected by the air bubble, and the generated voltage intensity is also different. When the angle changes, the position of the air bubble in the first liquid storage box 34 will change, thereby changing the projection position on the photosensitive component, that is, the angle change of the instrument. Therefore, the output voltage value will also fluctuate, and the levelness can be judged based on the voltage value.

[0032] As Figure 2 shown, the second base 20 has a through second installation cavity 27, which is a cylindrical cavity as a whole. At the same time, the upper opening has a larger diameter, while the bottom opening has a smaller diameter. The photosensitive component mainly includes a first circuit board 31 and a photosensitive element located on one side of the circuit board 31. It is fixed at the upper opening of the second installation cavity 27, and the photosensitive element faces the second installation cavity 27. And the top surface of the second base 20 is lower than the top surface of the first base 10, and this height difference forms a stop surface 13 at the connection of the two bases. Since the first circuit board 31 is a disc-shaped circuit board, the stop surface 13 is also arranged in an arc shape, which can play an anti-fooling role and limit the excessive movement of the first circuit board 31 towards the first base 10 side, facilitating the alignment and installation of the first circuit board 31 and improving usability.

[0033] It should be understood that the height of the first base 10 is not necessarily higher than that of the second base 20, and a limiting structure can be directly arranged around the first circuit board 31 to provide a stop surface, and this embodiment does not limit.

[0034] To support the first liquid storage box 34, an annular second step portion 22 protrudes from the side wall of the second installation cavity 27. In this embodiment, two second step portions 22 protrude from the inner wall of the second installation cavity 27, and the two are arranged up and down. The diameter of the lower second step portion 22 is relatively small. Therefore, first liquid storage boxes 34 of different sizes can be used in a matching manner, improving usability and flexibility.

[0035] It is conceivable that, to avoid errors or fluctuations in the results caused by shaking during monitoring, the first liquid storage box 34 needs to be fixed on the second step portion 22 without moving. Therefore, the diameters of the two need to match, or glue can be applied to the second step portion 22, and the next operation can be carried out after the glue solidifies.

[0036] Meanwhile, the light-emitting component includes a second circuit board 32 and a light-emitting element 33 (such as a light-emitting diode, etc.) fixed thereon. As Figure 3 shown, an upward first step portion 21 is provided around the bottom opening at the bottom of the second base 20, the second circuit board 32 is fixed therein, and the light-emitting element 33 is located within the range of the bottom opening. Preferably, the height of the second step portion 22 is at least greater than the thickness of the second circuit board 32, so that the second circuit board 32 does not protrude, and the bottom of the entire second base 20 is flatter and can fit more closely to the surface to be detected or the mounting surface.

[0037] Since power needs to be supplied to the first circuit board 31 and the second circuit board 32, wires are connected between the two. In this embodiment, it is selected to route the wires outside the second base 20 instead of inside, which can avoid interfering with the internal light-emitting element 33 and the first liquid storage box 34.

[0038] As Figure 1 shown, an interface 311 for connecting an external display device is also provided on the first circuit board 31. After photoelectric conversion and processing, an output signal is formed, and then the signal is output to the external display device through the interface 311 for digital display. Compared with the physical level bubble, the monitoring accuracy of the electronic level bubble is higher, and it can be monitored continuously in real time. Of course, a storage medium can also be set to record the inclination record, and the usability and flexibility are relatively high.

[0039] It is conceivable that the second circuit board 32 adopts an embedded design on the second base 20. Therefore, a guide groove 24 can be opened at the bottom of the second base 20 to allow the wire to pass through the guide groove 24, and the diameter of the wire is smaller than the depth of the guide groove 24 to further ensure the flatness of the bottom.

[0040] As Figure 1 can be seen, a mounting seat 25 is provided on the second base 20, and a mounting hole 26 is opened on the mounting seat 25. The level bubble 100 is fixed to the surface to be detected or the mounting surface through bolts. Preferably, the mounting seat 25 protrudes radially from the bottom of the second base 20, covering the rest except the part connected to the first base 10, and three mounting holes 26 are provided, which are arranged in an isosceles triangle on the mounting seat 25. A concave design is adopted between the mounting hole 26 at the apex position and the mounting holes 26 at the base angles, so the material consumption is reduced and the cost is lowered.

[0041] After being fixed to the position to be detected, the bottom of the first base 10 is located above the bottom of the second base 20, presenting a stepped structure. Such a design can reserve installation and operation space for the adjusting screw 43. Since it is only necessary to finely adjust the attitude of the physical spirit level when there is an error with the electronic spirit level, there is no need to frequently operate the adjusting screw 43. Therefore, an operation hole is provided in the exposed part of the adjusting screw 43, and a thin rod can be inserted to adjust when operation is needed, and the thin rod is taken out after the adjustment is in place.
