If the square is integrally formed, the right angle of the floor right angle measuring instrument 10 is fixed and constant at all times, thereby ensuring the detection accuracy of the floor right angle measuring instrument 10. The right-angle outer frame 20 or the square ruler can be made of steel material, or can be made of other materials with higher hardness and easy forming.

Further, the inner edge of the corner of the right-angle outer frame 20 may have a concave hole 26. During detection, the recessed hole 26 avoids interference between the 90-degree external angle of the floor 40 and the 90-degree internal angle of the right-angle outer frame 20, and can assist in positioning and accommodating the corners of the floor, so that the floor 40 can smoothly reach the corners of the right-angle outer frame 20 At right angles to the inner edge of the rim, impact damage to the floor or the right-angle outer frame 20 can also be avoided.

Further, the inner edge length of the first side 22 and the second side 24 may be greater than the side length of the floor.

As a result, the floor right angle measuring instrument 10 can be mounted on the floor more stably and quickly during the inspection, and the floor with a longer dimension can be inspected.

Further, the positioning piece 30 may be elongated. In the example shown in FIG. 1, the positioning sheet 30 is in the shape of a long rectangular sheet, and the positioning sheet 30 in the shape of a rectangular sheet is convenient for production, assembly, and operation. In addition, the positioning piece 30 may be in other long shapes, such as a long cylindrical shape, a trapezoidal long piece or long column, an irregular long piece or a long column, and the like.

Further, the number of positioning pieces 30 is at least one. In the example shown in FIG. 1, the number of positioning pieces 30 is two. In actual use, the number of positioning pieces 30 can be one, two, three, or four according to the length of the side of the floor to be detected and the length of the inner edge of the first side 22 and the second side 24 of the right-angled outer frame 20.

The fixed connection method can be detachable screw connection, welding, etc.

Furthermore, the distance between the first end 32 and the corner of the right-angled outer frame 20 may be equal to the distance between the second end 34 and the corner of the right-angled outer frame 20, which is symmetrical in appearance, which can assist the visual judgment of the right angle.

Furthermore, the first side 22 and the second side 24 of the right-angle outer frame 20 are used for erecting on two adjacent sides of the floor 40 to detect the right angle of the floor 40. In addition, the distance between the first end 32 and the corner of the right-angle outer frame 20 is greater than half of the length of the inner edge of the first side 22, which can make the floor right angle measuring instrument 10 less likely to tip over when measuring the floor.

Please refer to FIG. 2A, which is a schematic diagram of the appearance of another embodiment of the floor right angle measuring instrument 10 of the present invention. In order to achieve at least one of the advantages or other advantages, another embodiment of the present invention provides a floor right angle measuring instrument 10 including a right angle outer frame 20 and at least one positioning piece 30. The right-angle outer frame 20 has a first side 22 and a second side 24 perpendicular to each other. The positioning piece 30 is disposed on the upper side of the right-angled outer frame 20 and fixed to the first side 22 and the second side 24 to be erected on the surface of the floor. The first side 22 and the second side 24 are independent and relatively fixed by the positioning piece 30.

In the example shown in FIG. 2B, the right-angled outer frame 20 is formed by two independent right-angled outer frame parts 20A, 20B fixedly connected by positioning pieces 30, and a right-angled outer frame composed of two right-angled outer frame parts 20A, 20B There is a slot 28 at the inner edge of the corner of 20, and other connection methods can be provided without affecting the accuracy of the floor right angle measuring instrument 10. In the examples shown in FIGS. 1 and 2, the right-angled outer frame members 20A, 20B are elongated sheets, and the opposite sides of the first side 22 and the second side 24 are also linear. In addition, under the condition that the vertical accuracy at the intersection of the first side 22 and the second side 24 is stable, the right-angled outer frame parts 20A, 20B can have different shapes, such as a trapezoidal long column shape and a cylindrical shape with a vertical section. And so on, but in any case, the first side 22 and the second side 24 are always straight.

(4) During testing, the floor right angle measuring instrument 10 is better placed on the floor. When there is no positioning piece 30 on the upper side of the right-angle outer frame 20, the floor is at right angle The center of gravity of the degree measuring instrument 10 is unstable, and when the lengths of the first side 22 and the second side 24 are longer, it is less likely to be placed on the floor. After adding the setting piece 30, according to the principle of triangular stability, the center of gravity of the floor right angle measuring instrument 10 can be stabilized, and it can be more easily placed on the floor during detection, and the operation is convenient.

Please refer to Fig. 3, which is a schematic diagram of the structure of the floor right angle measuring instrument of the present invention when measuring the right angle of the floor. In order to achieve at least one of the advantages or other advantages, another embodiment of the present invention proposes a floor straight angle measuring instrument 10 to detect a floor straight angle detection process. After the floor 40 to be tested is determined, the floor right angle measuring instrument 10 is mounted on the right angle corners of the adjacent two sides of the floor 40 to be tested by grabbing the positioning piece 30, and passes through the corners of the right angle outer frame 20 The recessed holes 26 on the inner edge of the frame enable the corners of the floor 40 to smoothly and quickly reach the right angles of the inner edges of the corners of the right-angled outer frame 20.

Refer to FIG. 4 in conjunction with FIG. 3, which is a front view of the schematic structural diagram shown in FIG. 3. When the floor right angle measuring instrument 10 is mounted at the right angle corners of the two adjacent sides of the floor 40 to be tested, one of the first side 22 and the second side 24 in the right-angle outer frame 20 is close to the side to be tested The two adjacent sides of the floor 40 are at right angles. The other side of the first side 22 and the second side 24 and the other side at right angles of the two adjacent side surfaces of the floor 40 to be tested form a gap width S, as shown in the area B in FIG. 4.

A certain spacing width S is formed between the other side of the right-angle corners of two adjacent sides of the floor 40 to be detected and the second side 24 of the right-angled outer frame 20. Use a measuring tool to measure the value of the spacing width S at different positions in the B area. Then, the maximum value of the measured spacing width S is compared with the specified spacing width error value in the corresponding standard vertical angle measurement to determine whether the vertical angle of the detected corner of the floor 40 to be tested meets the requirements. In the illustrated embodiment of the present invention, a thickness gauge is used to measure and determine the maximum value of the pitch width S. When S is less than ±0.15 mm, it is determined that the straight angle of the tested floor 40 is qualified.
