[0034] Example 1

[0035] The following is for reference. Figures 1-6 The present invention describes a spirit level mounting structure and a spirit level assembly 100 according to an embodiment of the present invention.

[0036] like Figure 1 As shown, the first aspect of this utility model provides a spirit level mounting structure, which includes a base 1 and a bubble assembly 2. The base 1 defines a mounting cavity 11, and the cavity wall of the mounting cavity 11 is provided with a positioning groove 1110; the bubble assembly 2 is disposed in the mounting cavity 11; wherein, the bubble assembly 2 has a positioning part 21 and an adjusting part 22, the positioning part 21 is clearance-fitted with the positioning groove 1110, and the adjusting part 22 can be connected to an adjusting tool to adjust the position of the bubble in the bubble assembly 2 under the drive of the adjusting tool.

[0037] In a specific application scenario, after positioning the positioning part 21 of the bubble assembly 2 and aligning it with the positioning groove 1110 in the mounting cavity 11, the bubble assembly 2 is installed in the mounting cavity 11; then, the adjustment part 22 is connected by an adjustment tool, and the bubble position of the bubble assembly 2 is adjusted by driving the bubble assembly 2 to move through the adjustment tool.

[0038] It should be further explained that a spirit level is a practical tool used to measure horizontality and verticality. Therefore, the adjustment unit 22 can be connected to an adjustment tool to adjust the position of the bubble in the bubble assembly 2 under the action of the adjustment tool. In fact, it is necessary to bring the position of the bubble assembly 2 into a manually defined centering range, so that the bubble can deviate from the centering position in the vertical direction to indicate verticality, and can deviate from the centering position in the horizontal direction to indicate horizontality.

[0039] Compared to related technologies that involve repeatedly and alternately adjusting the tightness of the screws at both ends to center the bubble, this invention requires fewer steps when adjusting the position of the bubble in the bubble assembly 2, making the adjustment operation more convenient. This improves the ease of adjustment and the production efficiency of the level assembly.

[0040] As can be seen from the technical solution, the embodiments provided by this utility model have the following advantages: the positioning part 21 of the bubble assembly 2 and the positioning groove 1110 of the mounting cavity 11 of the base 1 are fitted together with a clearance, which realizes the initial positioning of the bubble assembly 2 and simplifies the installation process; and the adjustment part is connected to the adjustment tool to finely adjust the position of the bubble of the bubble assembly 2, which improves the convenience of adjustment and the production efficiency of the level assembly.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning groove 1110 is further constructed as an arc-shaped groove protruding from the center of the mounting cavity 11; the positioning part 21 is constructed as an arc-shaped block protruding from the outer surface of the bubble assembly 2.

[0042] The center of the mounting cavity 11 here refers to the geometric center of the mounting cavity 11 in three-dimensional space. By constructing the positioning groove 1110 as an arc-shaped groove and the positioning part 21 as an arc-shaped block, it is beneficial to improve the controllability of the movement trajectory of the positioning part 21, thereby making the adjustment process of the bubble position in the bubble assembly 2 smoother and more stable.

[0043] like Figure 3 As shown, the adjustment part 22 is further configured as an adjustment hole opened on the positioning part 21, thereby simplifying the overall structure and improving the compactness of the structure; and, after the adjustment tool is inserted into the adjustment hole on the positioning part, the applied adjustment force acts directly on the positioning part, the transmission of adjustment force is more direct and efficient, and the sensitivity and fine-tuning accuracy of adjustment are effectively improved.

[0044] Furthermore, the size of the adjusting hole is configured to be larger than the connecting end of the adjusting tool to allow for a free fit with the connecting end of the adjusting tool. Due to the gap, there is no continuous clamping force or mechanical interlock between the adjusting tool and the inner wall of the adjusting hole; the adjusting tool and the adjusting hole are only in contact when adjustment force is applied. After adjustment is completed and the adjustment force is removed, the adjusting tool and the adjusting hole are in contact. When the adjusting tool and the adjusting hole are pulled out, there is no physical contact between the adjusting tool and the adjusting hole, or only very slight, inconsequential contact, thereby reducing the impact on the position of the bubble assembly 2.

[0045] Example 2

[0046] like Figure 1 As shown, the level mounting structure further includes an adhesive structure 3, which is disposed between the base 1 and the bubble assembly 2.

[0047] In related technologies, the enormous concentrated pressure generated when tightening screws is applied to the bubble assembly. For a precision component like the bubble assembly, which contains a sensitive glass tube and liquid, this localized stress can easily cause minute deformations or displacements, thereby altering the already adjusted position of the bubble.

[0048] In this embodiment, an adhesive structure 3 is used to fix the base 1 and the bubble assembly 2. On the one hand, the adhesive structure 3 evenly transfers the load to the entire adhesive area through surface contact, completely eliminating the concentrated stress caused by screw fixing points. On the other hand, the curing of the adhesive structure 3 is a static process, unlike tightening screws which generates dynamic and uncontrollable torque and pressure. Before the adhesive cures, the position of the bubble assembly 2 can remain in a well-adjusted state without interference.

[0049] like Figure 2 and Figure 3 As shown, the adhesive structure 3 further includes an injection hole 31; the injection hole 31 is formed on the cavity wall of the mounting cavity 11 and / or the outer surface of the bubble assembly 2.

[0050] Optionally, the glue injection hole 31 is provided on the cavity wall of the mounting cavity 11; the glue injection hole 31 is not provided on the outer surface of the bubble assembly 2.

[0051] Optionally, the injection hole 31 is provided on the outer surface of the bubble assembly 2; the injection hole 31 is not provided on the cavity wall of the mounting cavity 11.

[0052] Optionally, injection holes 31 are provided on the outer surface of the bubble assembly 2 and on the cavity wall of the mounting cavity 11.

[0053] like Figures 2-4 As shown, the positioning groove 1110 is further provided with an injection hole 31 on its groove wall; and / or the positioning part 21 is provided with an injection hole 31.

[0054] Optionally, the glue injection hole 31 is provided on the groove wall of the positioning groove 1110; the positioning part 21 is not provided with the glue injection hole 31.

[0055] Optionally, the glue injection hole 31 is provided on the positioning part 21; the glue injection hole 31 is not provided on the groove wall of the positioning groove 1110.

[0056] Optionally, both the positioning part 21 and the positioning groove 1110 have glue injection holes 31 on their groove walls.

[0057] like Figure 1 and Figure 5 As shown, the cavity wall of the mounting cavity 11 is further constructed as an arc-shaped wall protruding away from the center of the mounting cavity 11; the surface of the bubble assembly 2 opposite to the cavity wall is constructed as an arc surface. This further improves the smoothness of fine-tuning. Furthermore, before the adhesive cures, the contact between the arc surface and the arc-shaped wall provides a certain degree of circumferential stability, helping to maintain the position of the bubble assembly 2.

[0058] In a specific example, the mounting cavity 11 is roughly square in shape. The mounting cavity 11 includes a first cavity wall 111, a second cavity wall 112, and a third cavity wall 113. The first cavity wall 111 has a positioning groove 1110. The second cavity wall 112 is adjacent to the first cavity wall 111, and the third cavity wall 113 is adjacent to the first cavity wall 111. The second cavity wall 112 and the third cavity wall 113 are positioned opposite each other. The other three cavity walls of the mounting cavity 11 are either open or not provided.

[0059] Both the second cavity wall 112 and the third cavity wall 113 are constructed as arc-shaped walls protruding from the center of the mounting cavity 11, and both the second cavity wall 112 and the third cavity wall 113 are provided with glue injection holes 31. The side of the bubble assembly 2 opposite to the second cavity wall 112 is constructed as a first arc-shaped surface 23; the side of the bubble assembly 2 opposite to the third cavity wall 113 is constructed as a second arc-shaped surface 24, and the second arc-shaped block matches the third cavity wall 113.

[0060] In summary, the level mounting structure of this embodiment can quickly adjust the position of the bubble assembly 2, the structure is stable and drop-resistant, the adjustment process is more stable and smooth, and the adjustment accuracy is higher.

[0062] like Figure 6As shown, a second aspect embodiment of the present invention provides a level assembly, which includes a level mounting structure according to the second aspect embodiment of the present invention; a base 1 is further provided with a first hollow area 12 and a second hollow area 13, the first hollow area 12 and the second hollow area 13 are connected to a mounting cavity 11, and a reflector 4 is provided in the mounting cavity 11; a bubble assembly 2 includes a bubble body 202 and a bubble support 201, the bubble support 201 is provided with a positioning part 21 and an adjustment part 22, and the bubble body 202 is installed in the mounting cavity 11 through the bubble support 201; a first transparent structure and a second transparent structure are provided on different sides of the bubble support 201 to display the bubble of the bubble assembly; the first transparent structure is disposed opposite to the first hollow area 12; the reflector 4 is obliquely disposed and can reflect the bubble body 202 displayed by the second transparent structure to the second hollow area 13.

[0063] By setting the above-mentioned level mounting structure, the positioning part 21 of the bubble assembly 2 and the positioning groove 1110 of the mounting cavity 11 of the base 1 are fitted together to achieve the initial positioning of the bubble assembly 2, which simplifies the installation process; and the adjustment part is connected to the adjustment tool to finely adjust the position of the bubble of the bubble assembly 2, which improves the convenience of adjustment and the production efficiency of the level assembly.

[0064] Furthermore, the level assembly in this embodiment can observe the position of the bubble body 202 from different directions, increasing the applicability of the level assembly.

[0065] Furthermore, the circumferential angle between the first hollowed-out area 12 and the second hollowed-out area 13 is 90°. The reflector 4 is installed in the mounting cavity 11 at an angle of 45°, thereby enabling the level assembly to measure both horizontality and verticality.

[0066] In a specific example, the bubble holder 201 is provided with a positioning part 21, an adjustment part 22 and an injection hole 31.

[0067] Furthermore, a reflector mounting part 14 is provided on the cavity wall of the mounting cavity 11; the reflector mounting part 14 includes a hook and a connecting part, the hook is connected to the cavity wall of the mounting cavity 11 through the connecting part and can abut against the reflector 4. The hook structure limits the reflector 4 to a preset optical path angle, ensuring the accuracy of the bubble reflection image; its snap-fit ​​assembly method greatly improves the installation efficiency and completely avoids the risk of mirror contamination caused by the use of adhesive.
