Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping, specifically to a three-in-one combination angle ruler that can be used in multiple ways. Background Technology

[0002] Squares are a common measuring tool in daily life, widely used in businesses, schools, and homes. Conventional squares can only measure dimensions in one direction, such as length using a right-angle ruler or angle using a protractor. This method of measurement usually requires carrying multiple squares, which are prone to being lost. Therefore, combination squares, which are more suitable for practical use, have appeared on the market, combining right-angle rulers and protractors. However, the mounting positions of current combination squares are relatively smooth, meaning that the right-angle ruler and protractor are mounted on flat surfaces without any mutual support. This inevitably leads to left-right wobbling during use, resulting in accuracy errors for products requiring precise angle measurements and making them inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a three-in-one combination angle ruler with stable structure and reduced measurement error.

[0004] To solve the aforementioned existing technical problems, this utility model adopts the following solution: a three-in-one combined angle ruler, including a support base, a first measuring scale, and a second measuring scale. The support base is movably connected to the first measuring scale and the second measuring scale respectively through adjusting nuts. The support base is provided with a first step groove and a second step groove. A snap-fit ​​block is integrally installed on the first step groove. The first step groove is snapped into a sliding groove on the first measuring scale through the snap-fit ​​block. The surface of the first measuring scale is provided with a through groove. The second step groove is integrally provided with a first arc-shaped block and a second arc-shaped block, wherein the first arc-shaped block is connected to the arc-shaped positioning groove on the second measuring scale, and the second arc-shaped block is connected to the arc-shaped limiting groove on the second measuring scale.

[0005] Preferably, the height of the first step groove is at the same horizontal plane as the height of the first measuring ruler.

[0006] Preferably, the two sides of the snap-fit ​​block are set at a vertical or inclined angle with a slope between them and the bottom of the first step groove.

[0007] Preferably, the groove at the bottom of the first measuring scale and the bottom of the second measuring scale are set at a vertical or inclined angle.

[0008] Preferably, the end of the second stepped groove is provided with an arc-shaped limiting seat, which matches the curvature of the back of the second measuring scale.

[0009] Preferably, the second measuring scale rotates along the arc-shaped limiting seat.

[0010] This utility model adopts the above-mentioned technical solution to provide a three-in-one combined angle ruler. By optimizing the connection structure between multiple angle rulers, it has the following advantages compared with the prior art: 1. When it is necessary to measure a specific item, the size and angle of the item can be measured simultaneously by using the first and second squares.

[0011] 2. The tightness of the second measuring scale can be adjusted by adjusting the nut, which can be used to measure items at different angles. Attached Figure Description

[0013] In the figure, the base is 1, the first measuring scale is 2, the second measuring scale is 3, the adjusting nut is 4, the first step groove is 5, the second step groove is 6, the snap block is 7, the slide is 8, the through groove is 9, the first arc-shaped block is 10, the second arc-shaped block is 11, the arc-shaped positioning groove is 12, the arc-shaped limiting groove is 13, and the arc-shaped limiting seat is 14. Detailed Implementation like Figure 1 , 2 As shown in Figure 3, a three-in-one combination square includes a support base 1, a first measuring scale 2, and a second measuring scale 3. The support base 1 is movably connected to the first measuring scale 2 and the second measuring scale 3 via adjusting nuts 4. The support base 1 has a first stepped groove 5 and a second stepped groove 6. A snap-fit ​​block 7 is integrally installed on the first stepped groove 5, and the first stepped groove 5 is snapped into a sliding groove 8 on the first measuring scale 2 via the snap-fit ​​block 7. The surface of the first measuring scale 2 has a through groove 9. The second stepped groove 6 has a first arc-shaped block 10 and a second arc-shaped block 11 integrally installed, wherein the first arc-shaped block 10 is connected to the sliding groove 8 on the second measuring scale 3. The arc-shaped positioning groove 12 is connected, the second arc-shaped block 11 is connected to the arc-shaped limiting groove 13 on the second measuring scale 3, the height of the first step groove 5 is at the same horizontal plane as the height of the first measuring scale 2, the two sides of the snap-fit ​​block 7 are set at a vertical or inclined angle with a slope between them and the bottom of the first step groove 5, the sliding groove 8 at the bottom of the first measuring scale 2 is set at a vertical or inclined angle with a slope between it and the bottom of the second measuring scale 3, the end of the second step groove 6 is provided with an arc-shaped limiting seat 14, the arc-shaped limiting seat 14 matches the arc of the back of the second measuring scale 3, and the second measuring scale 3 rotates along the arc-shaped limiting seat 14.

[0014] In actual operation, the first measuring scale 2 is installed on the first stepped groove 5, connecting the locking block 7 to the sliding groove 8. Then, the second measuring scale 3 is installed on the second stepped groove 6, with the arc surface of the end of the second measuring scale 3 fitting against the end of the second stepped groove 6. The first measuring scale 2 and the second measuring scale 3 are then fixed to the base 1 using the adjusting nut 4. During use, an angle is provided between the first measuring scale 2 and the second measuring scale 3. The first measuring scale 2 is placed against the bottom of the workpiece to be measured, allowing the first measuring scale 2 and the second measuring scale 3 to clamp the workpiece. The angle can be adjusted by the adjusting nut 4 as needed. The position of the first measuring scale 2 can be adjusted, or the adjusting nut 4 can be rotated to adjust the angle between the first measuring scale 2 and the second measuring scale 3. The angle between the first measuring scale 2 and the second measuring scale 3 is consistent with the scale on the second measuring scale 3. At this time, the length and angle of the workpiece can be measured simultaneously. Since one of the locking block 7 or the slide 8 is set at an inclined angle, there will be a left and right lateral force when the locking block 7 and the slide 8 are installed and connected. This can effectively avoid shaking during use, increase the measurement accuracy, and make it more convenient to use.
