In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0024] A portable slope angle measuring device provided in the embodiment, referring to Figure 1-Figure 6 As shown, it includes a main frame 1, a fitting frame 2, a hinge block 5, a sliding frame 6 and an infrared emitting source 8.

[0025] like Figure 1 , Figure 3 and Figure 5As shown, a level 11 is fixedly provided on the top of the main frame 1, and the user relies on the level 11 to determine whether the main frame 1 is in a horizontal state. A fitting frame 2 is hinged on the first end of the main frame 1, and the fitting frame 2 can be opened downward relative to the main frame 1, so that the fitting frame 2 fits the position on the slope 12 where the inclination angle needs to be measured. An arc frame 3 is fixedly connected to the top of the fitting frame 2. A guide hole 4 is provided on the main frame 1, and the arc frame 3 is located in the guide hole 4, so that the arc frame 3 and the main frame 1 are slidably matched, thereby ensuring the stability of the main frame 1 and the fitting frame 2 during opening and closing movements. An angle mark is provided on the arc frame 3, that is, the angle displayed by the angle mark position where the top of the main frame 1 is aligned with the arc frame 3 is the opening and closing angle of the main frame 1 and the fitting frame 2. When in use, the main frame 1 is kept in a horizontal state, and the fitting frame 2 fits the position on the slope 12 where the inclination angle needs to be measured. The angle displayed by the angle mark position where the top of the main frame 1 is aligned with the arc frame 3 is the angle of the slope at the measured position. In order to prevent the fitting frame 2 from rotating during use, a second fastening screw 15 is threadedly installed on the side of the main frame 1, and one end of the second fastening screw 15 is located in the guide hole 4. The second fastening screw 15 is used to fix the arc frame 3 and the main frame 1. When the second fastening screw 15 is tightened, the arc frame 3 can be fixed to the main frame 1. At this time, the fitting frame 2 cannot rotate relative to the main frame 1.

[0026] like Figure 1 , Figure 3 and Figure 5 As shown, an extension frame 1c is fixedly provided on the second end of the main frame 1, and the hinge block 5 is hinged at the end of the extension frame 1c, and is slidably connected to the sliding frame 6 through the hinge block 5. After the connection, the sliding frame 6 can slide relative to the hinge block 5, so that the sliding frame 6 can be vertically slid and adjusted, and an infrared emitting source 8 is fixedly connected to the side of the sliding frame 6, so that the height of the infrared emitting source 8 can be vertically adjusted. When the main frame 1 is in the open state, it is perpendicular to the sliding frame 6. The extension frame 1c (i.e., the main frame 1) can rotate 90 degrees up and down along the hinge block 5, and a limiting right-angle frame 14 is fixedly connected to the side of the hinge block 5 to limit it. The main frame 1 is rotated 90 degrees upward along the hinge block 5, and the main frame 1 can be folded so that it is in the same line as the sliding frame; when the main frame 1 is rotated 90 degrees downward along the hinge block 5 to open, the limiting right-angle frame 14 abuts against the end of the extension frame 1c to limit it. At this time, the hinge block 5 and the extension frame 1c (i.e., the sliding frame 6 and the main frame 1) are perpendicular to each other. When the main frame 1 is in a horizontal state, the hinge block 5 and the sliding frame 6 connected to the hinge block 5 are in a vertical state, and a scale 6b is provided on the side of the sliding frame 6.

[0027] When the measuring device of the utility model is not in use, the fitting frame 2 can be folded upward and close to the bottom of the main frame 1, and then the main frame 1 is rotated 90 degrees upward along the hinge block 5, or the sliding frame 6 is rotated 90 degrees downward along the hinge block 5, so that the main frame 1 and the sliding frame 6 are folded to the same straight line. The folded device has a compact structure and is easy to carry and use. In order not to affect the folding, the length of the main frame 1 is greater than the sliding frame 6, and the arc frame 3 and the guide hole 4 are both arranged at an end away from the sliding frame 6, and the arc frame 3 is arranged at the end of the main frame 1 that is longer than the sliding frame 6. When the sliding frame 6 and the main frame 1 are folded, the arc frame 3 is located outside the sliding frame 6, which will not affect the folding of the two.

[0028] In one embodiment, if Figure 5 As shown, a frame opening 1b is provided at the bottom of the main frame 1. When the fitting frame 2 is folded, the fitting frame 2 is inserted into the frame opening 1b, so that the folding and storage effect can be better. Figure 1 As shown, a protrusion 1a matching the slide groove on the sliding frame 6 is provided on the top of the main frame 1, and after the sliding frame 6 and the main frame 1 are folded, a sliding fit can be formed between the protrusion 1a on the top of the main frame 1 and the slide groove on the sliding frame 6. Some of the sliding frame 6 adjacent to the main frame 1 are fixedly connected with a clamping plate 6a, and the clamping plate 6a has two, and the two clamping plates can be clamped at the position of the protrusion 1a.

[0029] In one embodiment, if Figure 1 and Figure 2 As shown, the bottom end of the sliding frame 6 is fixedly connected with an anti-collision block 7, which is made of elastic rubber material and plays a role of buffering and protection to prevent the bottom end of the sliding frame 6 from colliding with the ground of the slope 12; a sliding hole 9 is opened on the side of the sliding frame 6, and a first fastening screw 10 is installed in the sliding hole 9. The first fastening screw 10 passes through the sliding hole 9 and is threadedly installed with the hinge block 5. The first fastening screw 10 is tightened, and the end head of the first fastening screw 10 squeezes the outer side of the sliding frame 6, so that the sliding frame 6 and the hinge block 5 are fixed together.

[0030] like Figure 6As shown in the figure, the portable slope angle measuring device of the utility model is used to measure the slope angle at a certain point on the slope 12. An operator sets up a benchmark 13 at the starting section of the slope 12, and a height mark is set on the side of the benchmark 13. Another operator operates the portable slope angle measuring device to fit the fitting frame 2 on the slope 12, and then adjusts the main frame 1 to be horizontal, reads the angle mark on the arc frame 3, and thus measures the inclination angle of the slope 12 at the measuring position. The infrared light emitted by the infrared emitting source 8 irradiates the benchmark 13, and the first height value is read from the benchmark 13. The value of the scale 6b is read from the sliding frame 6 as the second height value (taking the top of the hinge block 5 as the reference, reading the value corresponding to the scale on the sliding frame 6 aligned with the top of the hinge block 5), and the actual height of the slope can be calculated, and the actual height of the slope = the first height value + the second height value.

[0031] When actually in use, the sliding frame 6 is generally fixed to the hinge block 5, that is, the second height value is fixed; the height of the sliding frame 6 can also be slid to adjust the infrared emission source so that the infrared emission source irradiates a fixed position on the benchmark 13, that is, the first height value is fixed.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
