Description

Technical Field

[0001] This utility model belongs to the field of measuring equipment technology, specifically relating to a level detection device and measuring equipment. Background Technology

[0002] Existing measuring devices typically rely on observing the physical bubble position on their leveling device to determine whether the device is level. Taking a balance as an example, if the user forgets to calibrate the leveling position before weighing, and the measuring device is not actually level, it will lead to errors in the weighing results, affecting the accuracy of the weighing. When the ambient light around the leveling device is insufficient, it is difficult to clearly observe the position of the bubble, affecting the accuracy of the leveling calibration.

[0003] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a level detection device and measuring equipment. Utility Model Content

[0004] The purpose of this invention is to provide a level detection device and measuring equipment that can solve the problem of difficulty in clearly observing the position of the bubble, which affects the accuracy of level calibration.

[0024] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0025] Reference Figure 1 and Figure 2 This utility model discloses a level detection device, including a housing 1, a bubble level 2 installed inside the housing 1, and an illumination unit 3. A first observation port 11 is provided at one axial end of the housing 1, exposing the observation surface 21 of the bubble level 2. On a plane perpendicular to the axial direction of the housing 1, there is no overlap between the vertical projections of the illumination unit 3 and the bubble level 2. A bubble is provided at the observation surface 21 of the bubble level 2 to facilitate level calibration by observing the position of the bubble.

[0026] Therefore, in the level detection device of this utility model, the observation surface 21 of the bubble level 2 can be observed through the first observation port 11, and the illumination unit 3 can illuminate the bubble level 2, thereby facilitating the observation of bubbles under different lighting conditions to assist in the level calibration operation. The bubble level 2 can be made of a material with good light transmittance. Compared to the comparative design, where the illumination unit 3 is arranged adjacent to the observation surface 21 of the bubble level 2, i.e., the illumination unit 3 is located on the observation path, in this embodiment, since there is no overlapping area between the vertical projections of the illumination unit 3 and the bubble level 2, the bubble image is clear and unobstructed whether the bubble position is observed manually or obtained by an automatic detection device, which helps to ensure the accuracy of level calibration.

[0027] Reference Figure 2The lighting unit 3 includes a light source. On a plane perpendicular to the axis of the housing 1, the vertical projection of the light source is located around the outer periphery of the vertical projection of the bubble level 2. At least one light source is positioned around the bubble level 2 to illuminate it. Specifically, there can be one, two, three, or even more light sources. It is understood that the placement of at least one light source ensures that there is no overlapping area between the light source and the vertical projection of the bubble level 2, thus guaranteeing effective illumination of the bubble level 2 without obstructing the line of sight. The light source can be an LED light or other lighting fixtures.

[0028] In one optional embodiment, when multiple light sources are provided, they can be evenly arranged around the bubble level 2 to uniformly illuminate the bubble level 2, thereby facilitating the observation of the bubble position.

[0029] Reference Figure 2 and Figure 3 In one optional embodiment, the lighting unit 3 further includes a light-transmitting annular cover 31. A light source is mounted on the annular cover 31, which is fitted around the outer periphery of the bubble level 2, exposing the observation surface 21 of the bubble level 2. The annular cover 31 facilitates the attachment and installation of the light source. Specifically, the light source can be installed on the inner wall of the annular cover 31, or the interior of the annular cover 31 can be hollow, with the light source installed within the hollow space. At least one light source can be mounted on the annular cover 31. In this embodiment, the annular cover 31 can be made of PC material.

[0030] Reference Figure 3 The inner wall of the outer casing 1 has a protruding abutment portion 13, on which the lighting unit 3 can be abutted and installed. In this embodiment, the abutment portion 13 is stepped, which can be used to hold the annular cover 31, thereby facilitating the positioning and installation of the lighting unit 3. In an optional embodiment, the abutment portion 13 may also be provided with a groove, and the lighting unit 3 may also be provided with a plug-in portion, which is inserted into the groove, to further improve the convenience and stability of installing the lighting unit 3.

[0031] Reference Figure 2 and Figure 3 In this embodiment, the level detection device further includes a camera module 4, which is located on the side of the bubble level 2 away from the first observation port 11, to acquire images of the bubble position in the bubble level 2. The camera module 4 enables automatic detection of the bubble position in the bubble level 2, thereby achieving automated detection.

[0032] In contrast to the comparative design, where the camera module 4, bubble level 2, and illumination unit 3 are arranged in a straight line, with the bubble level 2 positioned between the camera module 4 and the illumination unit 3, the position of either the camera module 4 or the illumination unit 3 obstructs the view for manual observation, limiting its functionality to automatic detection. In this application, because the illumination unit 3 is located around the bubble level 2, and the camera module 4 is located on the side of the bubble level 2 away from the first observation port 11, the level detection device of this application has dual functionality. That is, during automatic detection, the camera module 4 automatically acquires the position of the bubble in the bubble level 2. During manual detection, the position of the bubble in the bubble level 2 can be directly observed through the first observation port 11, without any structural obstruction of the view.

[0033] Reference Figure 2 Furthermore, the level detection device also includes a polarizer 5 that is fitted into the first observation port 11 of the housing 1. The polarizer 5 reduces the interference of ambient light on the imaging of the camera module 4, while not affecting manual observation of the bubble level 2 through the first observation port 11.

[0034] Reference Figure 2 The level detection device also includes a cover plate 6 covering the first observation port 11 of the outer casing 1, and the cover plate 6 has a second observation port 61 that exposes the observation surface 21 of the bubble level 2. In this embodiment, the cover plate 6 can be configured as an annular cover plate 6, and its inner ring can form the second observation port 61. In other embodiments, it can also be other shapes, and this application does not impose specific limitations on it.

[0035] Reference Figure 2 Furthermore, on a plane perpendicular to the axis of the outer casing 1, the vertical projection of the lighting unit 3 is located within the vertical projection of the cover plate 6. Since the horizontal detection device of this application has the function of manual observation, the structural design of the cover plate 6 can block the light from the lighting unit 3 illuminating the first observation port 11, thereby avoiding glare when observing manually through the first observation port 11 and optimizing the user experience.

[0036] Reference Figure 2 The outer casing 1 has a connecting part 12 at one end near the cover plate 6. Both the connecting part 12 and the cover plate 6 have connecting holes 7. The cover plate 6 and the connecting part 12 are fixedly connected at the connecting holes 7 by fasteners 8. The connecting part 12 is the side wall of the outer casing 1 adjacent to the cover plate 6, and the fasteners 8 can be screws.

[0037] Reference Figure 1In one embodiment of this utility model, a measuring device is also disclosed, including the aforementioned level detection device. It is understood that the measuring device equipped with the aforementioned level detection device allows the illumination unit 3 to illuminate the bubble level 2, thereby facilitating level calibration by observing the bubble under different lighting conditions. Simultaneously, whether the bubble position is observed manually or obtained by an automatic detection device, the bubble image is clear and unobstructed, which helps ensure the accuracy of level calibration. The measuring device in this embodiment includes, but is not limited to, balances, levels, total stations, and other measuring devices that require bubble leveling; these will not be listed individually in this application.

[0038] It will be apparent to those skilled in the art that this disclosure is not limited to the details of the exemplary embodiments described above, and that this disclosure can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
