Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1.
[0028] like Figures 1-4 As shown, this utility model provides a square for measuring the perpendicularity of an end structure, including a square plate A1 and a square plate B2. The inner side A3 of the square plate A1 and the inner side B4 of the square plate B2 are perpendicular to each other, and the outer side A5 of the square plate A1 and the outer side B6 of the square plate B2 are perpendicular to each other. The intersection of the outer side A5 and the outer side B6 is chamfered, and a clearance groove 7 is provided at the intersection of the inner side A3 and the inner side B4. A leveling structure is provided on the square plate A1. The square plates A1 and B2 are perpendicular to each other and are an integral structure.
[0029] This utility model features a simple and scientifically designed angle ruler 16 for measuring the perpendicularity of end structures. It is easy to use and can be used to measure the perpendicularity of two inner surfaces (lines) or two outer surfaces (lines) of the structure being measured 17. When measuring the perpendicularity of buildings, components, and product structures, it effectively avoids interference at the ends, ensuring measurement accuracy. It can also measure the horizontal or verticality of the structure being measured. This effectively solves the technical problem in existing technologies where interference easily occurs between the intersection of the measured structure and the end of the angle ruler, affecting the accuracy of perpendicularity measurements.
[0030] Example 2.
[0031] like Figures 1-4 As shown, this utility model provides a square for measuring the perpendicularity of an end structure, including a square plate A1 and a square plate B2. The inner side A3 of the square plate A1 and the inner side B4 of the square plate B2 are perpendicular to each other, and the outer side A5 of the square plate A1 and the outer side B6 of the square plate B2 are perpendicular to each other. The intersection of the outer side A5 and the outer side B6 is chamfered, and a clearance groove 7 is provided at the intersection of the inner side A3 and the inner side B4. A leveling structure is provided on the square plate A1. The square plates A1 and B2 are perpendicular to each other and are an integral structure.
[0032] The leveling structure includes a mounting hole A8 opened on the square plate A1, a vertical plate 10 installed in the mounting hole A8 and distributed on the same plane as the square plate A1, and a level bubble A9 installed on the vertical plate 10.
[0033] Based on Example 1, Example 2 provides a more preferred structure for the leveling structure, specifically: the leveling structure includes an assembly hole A8 opened on the square plate A1, a vertical plate 10 installed in the assembly hole A8 and distributed on the same plane as the square plate A1, and a level bubble A9 installed on the vertical plate 10.
[0034] The vertical plate 10 is mounted on the square plate A1 at both ends via connecting columns. Preferably, the connecting columns and the vertical plate 10 are an integral structure, as are the inner walls of the mounting holes A8 on the square plate A1. The overall structure is relatively solid and stable, effectively ensuring measurement accuracy. The vertical plate 10 and the square plate A1 are distributed on the same plane. When the bubble level A9 is horizontal, the square plate A1 is vertical. This effectively measures whether the component being measured is horizontal or vertical. When measurement is required, the square plate A1 is placed against the structure being measured, ensuring that the contact surface of the square plate A1 is in contact with the surface being measured.
[0035] Example 3.
[0036] like Figures 1-4 As shown, this utility model provides a square for measuring the perpendicularity of an end structure, including a square plate A1 and a square plate B2. The inner side A3 of the square plate A1 and the inner side B4 of the square plate B2 are perpendicular to each other, and the outer side A5 of the square plate A1 and the outer side B6 of the square plate B2 are perpendicular to each other. The intersection of the outer side A5 and the outer side B6 is chamfered, and a clearance groove 7 is provided at the intersection of the inner side A3 and the inner side B4. A leveling structure is provided on the square plate A1. The square plates A1 and B2 are perpendicular to each other and are an integral structure.
[0037] The leveling structure includes a mounting hole A8 opened on the square plate A1, a vertical plate 10 installed in the mounting hole A8 and distributed on the same plane as the square plate A1, and a level bubble A9 installed on the vertical plate 10.
[0038] When the bubble level A9 is horizontal, the vertical plate 10 is perpendicular to the horizontal plane.
[0039] Based on Example 2, this embodiment 3 provides a more preferred structure for the leveling structure. Specifically, when the level bubble A9 is horizontal, the vertical plate 10 is perpendicular to the horizontal plane. The vertical plate 10 and the angle plate A1 are distributed on the same plane. When the level bubble A9 is horizontal, the angle plate A1 is in a vertical state. This can effectively measure whether the component being measured is in a horizontal or vertical state. When measurement is required, the angle plate A1 is attached to the structure being measured, so that the contact surface of the angle plate A1 is in contact with the measurement surface of the structure being measured.
[0040] Example 4.
[0041] like Figures 1-4As shown, this utility model provides a square for measuring the perpendicularity of an end structure, including a square plate A1 and a square plate B2. The inner side A3 of the square plate A1 and the inner side B4 of the square plate B2 are perpendicular to each other, and the outer side A5 of the square plate A1 and the outer side B6 of the square plate B2 are perpendicular to each other. The intersection of the outer side A5 and the outer side B6 is chamfered, and a clearance groove 7 is provided at the intersection of the inner side A3 and the inner side B4. A leveling structure is provided on the square plate A1. The square plates A1 and B2 are perpendicular to each other and are an integral structure.
[0042] A spirit level B11 is provided on the angle ruler B2.
[0043] Based on Example 1, this embodiment 4 provides a more preferred structure for the square plate B2, specifically: the square plate B2 is equipped with a level bubble B11. When in use, the square plate B2 is placed against the structure being measured, ensuring close contact between the contact surface of the square plate B2 and the measured surface of the structure. This allows for the measurement of the horizontal state of the measured surface. If combined with the measurement results of the level bubble A9, the two can be mutually verified, ensuring more accurate measurement results and avoiding the large errors inherent in single leveling measurements.
[0044] Example 5.
[0045] like Figures 1-4 As shown, this utility model provides a square for measuring the perpendicularity of an end structure, including a square plate A1 and a square plate B2. The inner side A3 of the square plate A1 and the inner side B4 of the square plate B2 are perpendicular to each other, and the outer side A5 of the square plate A1 and the outer side B6 of the square plate B2 are perpendicular to each other. The intersection of the outer side A5 and the outer side B6 is chamfered, and a clearance groove 7 is provided at the intersection of the inner side A3 and the inner side B4. A leveling structure is provided on the square plate A1. The square plates A1 and B2 are perpendicular to each other and are an integral structure.
[0046] A spirit level B11 is provided on the angle ruler B2.
[0047] When the spirit level B11 is horizontal, the angle rulers B2 and A1 are also horizontal.
[0048] Based on Example 4, this embodiment 5 provides a more preferred structure for the square plate B2. Specifically, when the bubble level B11 is horizontal, both the square plate B2 and the square plate A1 are horizontal. During use, the bubble level B11 on the square plate B2 is used to bring the square plate B2 into close contact with the structure being measured, ensuring that the contact surface of the square plate B2 is tightly fitted with the measured surface of the structure. This allows for the measurement of the horizontal state of the measured surface of the structure. If combined with the measurement results of the bubble level A9, the two can be mutually verified, ensuring more accurate measurement results and avoiding the large errors inherent in single-leveling measurements.
[0049] Example 6.
[0050] like Figures 1-4 As shown, this utility model provides a square for measuring the perpendicularity of an end structure, including a square plate A1 and a square plate B2.

The intersection of the outer side A5 and the outer side B6 is chamfered, and a clearance groove 7 is provided at the intersection of the inner side A3 and the inner side B4. A leveling structure is provided on the square plate A1. The square plates A1 and B2 are perpendicular to each other and are an integral structure.
[0051] The clearance slot 7 can be a triangular structure, a polygonal structure, or a circular structure.
[0052] Based on Embodiment 1, this Embodiment 6 provides a more preferred structure for the clearance groove 7, specifically: the clearance groove 7 is a triangular structure, a polygonal structure, or a circular structure. Since the clearance groove 7 has diverse structural forms, a set of angle rulers can be made for each style of clearance groove 7. By combining angle rulers of different clearance groove 7 structural styles into a set, this set of angle rulers can be applied to a wider range of structures, including buildings, components, and products, effectively expanding the scope of application of this invention.

[0055] The chamfer at the intersection of outer edge A5 and outer edge B6 is a rounded chamfer 14.
[0056] Based on Example 1, Example 7 provides a more preferred structure for the angle ruler, specifically: the chamfer at the intersection of outer side A5 and outer side B6 is rounded. The rounded chamfers on the outer sides of angle ruler plates A1 and B2 are suitable for measuring the perpendicularity of the measured surface or line, whether the intersection is chamfered or not.
[0057] Example 8.
[0058] like Figures 1-4As shown, this utility model provides a square for measuring the perpendicularity of an end structure, including a square plate A1 and a square plate B2.

The 45-degree chamfer on the outer sides of angle ruler plates A1 and B2 is suitable for measuring the perpendicularity of surfaces or lines where a 45-degree chamfer is appropriate.

[0064] Based on Embodiment 1, this embodiment 9 provides a more preferred structure for the square plate A1, specifically: a hole A12 is provided on the square plate A1.
