It should be noted that, unless there is a conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] See also Figures 1 to 4 The figure shows the preferred structure of the angle measuring device in this embodiment. As shown, the angle measuring device includes a dial 1, a first measuring device 2, a second measuring device 3, and a leveling mechanism. The dial 1 is provided with an angle scale. Specifically, the dial 1 is circular and has 360° graduations. In a specific implementation, the dial 1 can be made of stainless steel.

[0022] A leveling mechanism is provided on the dial 1 and is used to level the dial 1. Specifically, the leveling mechanism includes a first leveling bubble 5 and a second leveling bubble 6. The first leveling bubble 5 is provided on the dial 1, while the second leveling bubble 6 is provided perpendicular to the dial 1. The first and second leveling bubbles 5, 6 are used to maintain the dial 1 in a horizontal or vertical position. Specifically, the first leveling bubble 5 is provided horizontally on the dial 1, while the second leveling bubble 6 is provided vertically on the dial 1.

[0023] The first measuring instrument 2 and the second measuring instrument 3 are both rotatably arranged on the dial 1. The first measuring instrument 2 is used to align with the reference line, and the second measuring instrument 3 is used to point to the angle required by the design.

[0024] When installing a pipe with an angle, align the first measuring instrument 2 with the designed reference line, point the second measuring instrument 3 to the required angle according to the design requirements, then level the dial 1 using the first leveling bubble 5 and the second leveling bubble 6, and then determine the installation position of the pipe according to the direction of the second measuring instrument 3, so that the angle between the pipe and the reference line is the angle required by the design.

[0025] It can be seen that in this embodiment, according to the angle scale on the dial 1, the first measuring instrument 2 is aligned with the reference line, the second measuring instrument 3 points to the desired design angle, and the leveling mechanism levels the dial 1. At this time, the position pointed to by the second measuring instrument 3 is the installation position of the pipeline, so that the angle of the pipeline meets the design requirements, ensuring the accuracy of the pipeline installation position, improving the installation accuracy of the pipeline, and realizing the precise installation of the pipeline with a deflection angle, thereby solving the problem that the prior art cannot accurately install the pipeline with a deflection angle.

[0026] Continue to see Figure 1 、 Figure 2 and Figure 4 In the above embodiment, the first measuring device 2 includes: two first mounting plates 21, a first connecting plate 22 and a first irradiation device 23. The two first mounting plates 21 are arranged side by side, that is, the two first mounting plates 21 are parallel to each other, and there is a preset distance between the two first mounting plates 21. The first connecting plate 22 is vertically clamped between the first ends ( Figure 2 Specifically, the first connecting plate 22 is placed between the first ends of the two first mounting plates 21, and the first connecting plate 22 is perpendicular to the first ends of the two first mounting plates 21, so that the two first mounting plates 21 and the first connecting plate 22 form a U-shaped structure with one end open.

[0027] The scale plate 1 is inserted between the two first mounting plates 21 from the open end of the U-shaped structure, and part of the scale plate 1 is rotatably placed in the U-shaped structure. In other words, the scale plate 1 is not placed in the U-shaped structure as a whole, but the second ends ( Figure 2 The left end shown in the figure is rotatably connected to the center of the dial 1, so the dial 1 can rotate freely in the U-shaped structure, that is, the second ends of the two first mounting plates 21 can rotate freely 360° around the center of the dial 1.

[0028] Since the scale plate 1 is inserted between the two first mounting plates 21, one of the first mounting plates 21 is placed above the scale plate 1, and the other first mounting plate 21 is placed below the scale plate 1. The first mounting plate 21 placed above the scale plate 1 is provided with a first scale window 211. The first scale window 211 can be an opening provided on the first mounting plate 21 placed above the scale plate 1. The purpose of the first scale window 211 is to facilitate reading the scale on the scale plate 1.

[0029] The first irradiation device 23 is disposed on the first connecting plate 22. Specifically, the first connecting plate 22 defines a first emission port 221. The first irradiation device 23 is disposed within the U-shaped structure of the first measuring instrument 2. Furthermore, the first irradiation device 23 is disposed adjacent to the first connecting plate 22, with the emission end of the first irradiation device 23 corresponding to the first emission port 221, so that light emitted by the first irradiation device 23 can pass through the first emission port 221. More specifically, the first irradiation device 23 is positioned between the two first mounting plates 21 and adjacent to the first connecting plate 22. The emission end of the first irradiation device 23 faces the first emission port 221, so that light emitted by the first irradiation device 23 can be emitted through the first emission port 221.

[0030] Preferably, the first connecting plate 22 is provided with a protective glass at the first emission port 221 , and the protective glass can protect the emission end of the first irradiation device 23 . Specifically, the protective glass is circular and is provided in the first emission port 221 .

[0032] It can be seen that in this embodiment, the first measuring device 2 has a simple structure and is easy to implement.

[0033] See also Figures 1 to 4 In the above embodiment, the second measuring instrument 3 is rotatably disposed within the U-shaped structure of the first measuring instrument 2 and is rotatably connected to the scale plate 1. This allows the second measuring instrument 3 to freely rotate relative to the first measuring instrument 2, and the second measuring instrument 3 and the scale plate 1 to rotate relative to each other. This allows the first measuring instrument 2 to be rotated relative to the scale plate 1 until it aligns with the reference line, and the second measuring instrument 3 to be rotated relative to the scale plate 1 to the desired design angle.

[0034] The second measuring device 3 includes: two second mounting plates 31, a second connecting plate 32 and a second irradiation device 33. The two second mounting plates 31 are arranged side by side, that is, the two second mounting plates 31 are parallel to each other, and there is a preset distance between the two second mounting plates 31. The second connecting plate 32 is vertically clamped between the first ends ( Figure 3Specifically, the second connecting plate 32 is placed between the first ends of the two second mounting plates 31, and the second connecting plate 32 is perpendicular to the first ends of the two second mounting plates 31, so that the two second mounting plates 31 and the second connecting plate 32 form a U-shaped structure with one end open.

[0035] The scale plate 1 is inserted between the two second mounting plates 31 from the open end of the U-shaped structure of the second measuring instrument 3, and part of the scale plate 1 is rotatably placed in the U-shaped structure of the second measuring instrument 3. In other words, the scale plate 1 is not placed in the U-shaped structure of the second measuring instrument 3 as a whole, but is placed between the second ends ( Figure 3 The left end shown in the figure is rotatably connected to the center of the dial 1, so that the dial 1 can rotate freely in the U-shaped structure of the second measuring device 3, and the second ends of the two second mounting plates 31 can rotate freely around the center of the dial 1.

[0036] The two second mounting plates 31 of the second measuring instrument 3 are rotatably positioned within the U-shaped structure of the first measuring instrument 2. Specifically, the second measuring instrument 3 is entirely positioned within the U-shaped structure of the first measuring instrument 2 and is freely rotatable relative to the first measuring instrument 2. The second ends of the two second mounting plates 31 and the second ends of the two first mounting plates 21 are rotatably connected to the center of the scale plate 1. Specifically, the two second mounting plates 31 of the second measuring instrument 3 are inserted between the two first mounting plates 21 of the first measuring instrument 2, and the scale plate 1 is inserted between the two second mounting plates 31 of the second measuring instrument 3. Furthermore, both the first measuring instrument 2 and the second measuring instrument 3 are freely rotatable 360° relative to the scale plate 1.

[0037] Preferably, a connecting hole 11 is formed in the center of the dial 1. First through-holes 212 are formed at corresponding positions on the second ends of the two first mounting plates 21, and the positions of the first through-holes 212 on the two first mounting plates 21 correspond. Second through-holes 312 are formed at corresponding positions on the second ends of the two second mounting plates 31, and the positions of the second through-holes 312 on the two second mounting plates 31 correspond.

[0038] The first through-holes 212, the second through-holes 312, and the connecting hole 11 are aligned and then rotatably connected via the connecting bolts 4. Specifically, after the connecting bolts 4 are sequentially inserted through the aligned first through-holes 212, the second through-holes 312, and the connecting hole 11, the ends of the connecting bolts 4 are threadedly engaged with nuts. In this way, the two first mounting plates 21, the two second mounting plates 31, and the scale plate 1 can all rotate freely about the connecting bolts 4. Furthermore, the scale plate 1 is inserted between the two second mounting plates 31, and the two first mounting plates 21 are sleeved onto the outside of the two second mounting plates 31.

[0039] In a specific implementation, the distance between the two second mounting plates 31 is greater than the thickness of the dial 1, so that the two second mounting plates 31 can rotate outside the dial 1. The distance between the two first mounting plates 21 is greater than the distance between the two second mounting plates 31, so that the two first mounting plates 21 can rotate outside the two second mounting plates 31.

[0040] Since the dial 1 is inserted between the two second mounting plates 31, one of the second mounting plates 31 is placed above the dial 1, and the other second mounting plate 31 is placed below the dial 1. The second mounting plate 31 placed above the dial 1 is provided with a second scale window 311. The second scale window 311 can be an opening opened on the second mounting plate 31 placed above the dial 1. The purpose of the second scale window 311 is to facilitate reading the scale on the dial 1.

[0041] The second irradiation device 33 is disposed on the second connecting plate 32. Specifically, the second connecting plate 32 defines a second emitting port 321. The second irradiation device 33 is disposed within the U-shaped structure of the second measuring instrument 3. The second irradiation device 33 is disposed adjacent to the second connecting plate 32, with the emitting end of the second irradiation device 33 corresponding to the second emitting port 321, so that light emitted by the second irradiation device 33 can pass through the second emitting port 321. More specifically, the second irradiation device 33 is positioned between the two second mounting plates 31 and adjacent to the second connecting plate 32. The emitting end of the second irradiation device 33 faces the second emitting port 321, so that light emitted by the second irradiation device 33 can be emitted through the second emitting port 321.

[0042] Preferably, the second connecting plate 32 is provided with a protective glass at the second emission port 321 , and the protective glass can protect the emission end of the second irradiation device 33 . Specifically, the protective glass is circular and is provided in the second emission port 321 .

[0043] Preferably, the second irradiation device 33 is a rechargeable laser emitter.

[0044] It can be seen that in this embodiment, the second measuring device 3 has a simple structure and is easy to implement.

[0045] See also Figures 1 to 4When installing an angled pipe, align the two first holes 212 on the first measuring instrument 2, the two second holes 312 on the second measuring instrument 3, and the connecting hole 11 on the scale plate 1. Then, insert the connecting bolt 4 through the aligned first holes 212, second holes 312, and connecting hole 11, and screw them together with the nut. This allows the two second mounting plates 31 to be rotatably mounted on the outside of the scale plate 1, and the two first mounting plates 21 to be rotatably mounted on the outside of the two second mounting plates 31. After installation, direct the first illumination device 23 in the first measuring instrument 2 to the reference line, aligning the first measuring instrument 2 with the reference line. Direct the second illumination device 33 in the second measuring instrument 3 to the desired design angle. Use the first and second leveling bubbles 5 and 6 to level the scale plate 1. The position of the light emitted by the second illumination device 33 indicates the installation position of the pipe, and the pipe can then be installed.

[0046] In summary, in this embodiment, according to the angle scale on the dial 1, the first measuring instrument 2 is aligned with the reference line, the second measuring instrument 3 points to the desired design angle, and the leveling mechanism levels the dial 1. At this time, the position pointed to by the second measuring instrument 3 is the installation position of the pipeline, so that the angle of the pipeline meets the design requirements, ensuring the accuracy of the pipeline installation position, improving the installation accuracy of the pipeline, and realizing the precise installation of the pipeline with a deflection angle.
