Detailed implementation manners

[0024] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the specific embodiments disclosed in the following specification.

[0026] As Figures 1-6 shown, a positionable angle ruler includes a ruler base 1 and a ruler body 5. The ruler base 1 is detachably connected to the ruler body 5, and a pin shaft 16 that penetrates the ruler body 5 is threadedly connected to the inside of one side of the ruler base 1. By using the provided pin shaft 16, it is ensured that when measuring an angle, the ruler body 5 can rotate smoothly relative to the ruler base 1, and the detachable connection between the ruler base 1 and the ruler body 5 can be realized by removing the pin shaft 16:

[0027] An auxiliary seat 3 is fixedly connected through the ruler seat 1. A plurality of spring rods 13 are fixedly connected to the inner top of the auxiliary seat 3. The telescopic ends of the spring rods 13 are fixedly connected with anti-slip strips 12 that are slidably connected to the inner wall of the auxiliary seat 3. The two sides of the auxiliary seat 3 near both sides are vertically hollowed out. The two sides of the upper surface of the anti-slip strip 12 are rotatably connected with lower connecting rods 18 passing through the hollow parts of the auxiliary seat 3, and one ends of a plurality of lower connecting rods 18 located on the same side of the upper surface of the anti-slip strip 12 are rotatably connected with a pressing handle 4. The pressing handle 4 is located outside the auxiliary seat 3, and an upper connecting rod 11 passing through the hollow part of the auxiliary seat 3 is hinged between one side of the pressing handle 4 and the inner top surface of the auxiliary seat 3. Specifically, by applying pressure to the auxiliary seat 3, the ruler seat 1 is tightly attached to the surface of the object. And when pressing the auxiliary seat 3, by squeezing the two pressing handles 4, the two pressing handles 4 approach each other. By using the hinge of the upper connecting rod 11 with the inner top surface of the auxiliary seat 3 and the pressing handle 4, and the hinge of the lower connecting rod 18 with the pressing handle 4 and the anti-slip strip 12, the anti-slip strip 12 overcomes the pulling force of the spring rod 13 and supports, and slides downward along the inner wall of the auxiliary seat 3 until the surface of the anti-slip strip 12 contacts the surface of the object, and the position of the ruler seat 1 is fixed by using the friction between the anti-slip strip 12 and the object. On the contrary, when the anti-slip strip 12 is stored in the auxiliary seat 3, the ruler seat 1 can be slid to adjust the placement position, and the surface of the anti-slip strip 12 can be avoided from being damaged during the sliding process.

[0028] In addition: A chute 19 is opened on the surface of the ruler body 5 along the scale line direction. A reference block 6 is slidably connected in the chute 19. One side of the reference block 6 is rotatably connected with an anti-slip clip 20 through a snap spring. When using the ruler body 5 to measure the length, by sliding the reference block 6, it is convenient for the personnel to directly observe the actual position, and by using the anti-slip clip 20 to fit against the bottom of the chute 19 under the elastic force of the snap spring, the reference block 6 can be fixed on the ruler body 5, and then it is convenient for the personnel to take the ruler body 5 off for close observation.

[0029] In addition: A semi-circular track 7 is fixedly connected to the side of the ruler seat 1. The semi-circular track 7 is concentric with the pin shaft 16. And a clamping block 15 that is slidably connected to the inner and outer arc surfaces of the semi-circular track 7 is fixedly connected to the lower surface of the ruler body 5. A plurality of anti-slip lines 9 are machined on the upper surface of the semi-circular track 7. A fastening bolt 8 is threaded through the upper surface of the ruler body 5. The end surface of the fastening bolt 8 is rotatably connected with a rubber disc 17 that is embedded and engaged with the anti-slip lines 9. This solution is applicable to measuring the angle of an object by using the ruler body 5. During the measurement, the position of the ruler seat 1 is fixed, and then the ruler body 5 is rotated with the pin shaft 16 as the center. When the ruler body 5 rotates, the clamping block 15 will be driven to slide on the semi-circular track 7. After the angle measurement is completed, rotate the fastening bolt 8 and use the rubber disc 17 on the end surface of the fastening bolt 8 to tightly press against the anti-slip lines 9 on the semi-circular track 7, and the relative position of the fastening bolt 8 and the semi-circular track 7 can be fixed, and then the relative position of the ruler body 5 and the ruler seat 1 can be fixed, which is convenient for the personnel to take out the angle ruler for close observation.

[0030] In addition, for the convenience of personnel to read the measured angle: A number of arc-shaped scale rulers 2 are fixedly connected to the inner side of the ruler base 1. The number of arc-shaped scale rulers 2 is installed between the ruler base 1 and the ruler body 5 in the form of a telescopic joint. Among the number of arc-shaped scale rulers 2, a traction rope 14 is connected between two adjacent arc-shaped scale rulers 2. The unfolded length of the traction rope 14 is equal to the arc length of the arc-shaped scale ruler 2, that is, it is ensured that two adjacent arc-shaped scale rulers 2 will not be separated when sliding. The arc-shaped scale ruler 2 located on the outer side is fixedly embedded in the ruler base 1, and the end of the arc-shaped scale ruler 2 located on the inner side is rotatably connected to the bottom surface of the ruler body 5. The arc-shaped scale ruler 2 and the pin shaft 16 are concentrically arranged, and a number of angle scale reference holes 10 with equal radian are machined on each arc-shaped scale ruler 2. The same number and the same spacing of angle scale reference holes 10 are distributed on each arc-shaped scale ruler 2. That is, when the personnel rotate the ruler body 5 to drive the inner arc-shaped scale ruler 2 to slide out, after the traction rope 14 is straightened, the adjacent arc-shaped scale rulers 2 are slid out. That is, there is a certain number of arc-shaped scale rulers 2 or a part of the arc-shaped scale rulers 2 that are not completely pulled out between the ruler base 1 and the ruler body 5. By reading the angle scale reference holes 10, the angle sum of the number of arc-shaped scale rulers 2 between the ruler base 1 and the ruler body 5 can be judged, that is, it is convenient for the personnel to judge the rotation angle of the ruler body 5, that is, the measured angle.

[0031] Working principle: Place the angle ruler at the position to be measured, and after aligning the position of the ruler base 1, press the auxiliary seat 3, and by squeezing the two pressing handles 4, the two pressing handles 4 are made to approach each other. Utilize the hinge connection between the upper connecting rod 11 and the inner top surface of the auxiliary seat 3 and the pressing handle 4, and the hinge connection between the lower connecting rod 18 and the pressing handle 4 and the anti-slip strip 12 to realize that the anti-slip strip 12 overcomes the pulling force of the spring rod 13 and supports, and slides down along the inner wall of the auxiliary seat 3 until the surface of the anti-slip strip 12 contacts the surface of the object. Then rotate the ruler body 5 to the object to be measured, and by reading the number and angle of the angle scale reference holes 10 on the arc-shaped scale ruler 2 between the ruler body 5 and the ruler base 1, the included angle between the ruler body 5 and the ruler base 1 is obtained.

Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
