[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 As shown, an adjustable-angle engineering cost drawing measuring device includes a protractor 1 and a rotating shaft 4 fixed to one side of the surface of the protractor 1. Figure 2 As shown, an observation point is set at one end of the rotating shaft 4. This observation point is the center point for drawing the arc.

[0026] A support foot 2 is fixed to one side of the protractor 1, and a counterweight 3 is fixed to one side of the support foot 2. The bottom of the counterweight 3 and the bottom surface of the support foot 2 are on the same horizontal plane, and the counterweight 3 has a certain weight to provide support for the stability of the protractor 1.

[0027] A connecting block 5 is rotatably mounted on the surface of the rotating shaft 4. A ruler 6 is fixed to the other end of the connecting block 5. The bottom surface of the ruler 6 and the bottom surface of the support foot 2 are on the same horizontal plane. An observation line 7 is fixed on the surface of the connecting block 5. The observation line 7 is set on the central axis of the connecting block 5 and the ruler 6. Since the connecting block 5 is made of transparent material, it is convenient for staff to observe the angle between the ruler 6 and the protractor 1 through the observation line 7.

[0028] A first measuring surface 8 is provided on one side of the surface of the ruler body 6, and a second measuring surface 9 is provided on the other side of the surface of the ruler body 6. The measuring ratios of the first measuring surface 8 and the second measuring surface 9 are different, which improves the practicality of the measurement of this device.

[0029] The protractor 1, support foot 2, pivot 4, connecting block 5, and ruler 6 are all made of transparent acrylic.

[0030] A marking mechanism 10 is provided on the surface of the ruler body 6. One side of the ruler body 6 surface has a mating surface 13 for use with the marking mechanism 10. The marking mechanism 10 includes a placement block 101 that slides on the surface of the ruler body 6. The placement block 101 is a hollow cone shape. Sliders 102 are fixed to both sides of the surface of the placement block 101. A rotating rod 103 is rotatably mounted on the surface of one side of the slider 102. A threaded body 104 is formed on the surface of the rotating rod 103. A mating block 105 engages with the surface of the threaded body 104. The user can rotate the mating block 105, causing it to adhere to the surface of the mating surface 13 under the engagement of the mating block 105 and the threaded body 104. The mating force between the mating surface 13 and the mating block 105 restricts the position of the placement block 101. The inner cavity of the ruler body 6 has grooves 11 on both sides. The slider 102 slides in contact with the grooves 11. The grooves 11 restrict the sliding of the slider 102 and improve its stability. One end of the rotating rod 103 is fixed with a limiting block 12. The outer diameter of the limiting block 12 is larger than the outer diameter of the rotating rod 103. The limiting block 12 defines the range of movement of the bonding block 105 and prevents the bonding block 105 from detaching from the surface of the threaded body 104. The surface of the bonding surface 13 is provided with anti-slip particles 14. The anti-slip particles 14 are also provided on one side of the bonding block 105. In this embodiment, the anti-slip particles 14 provide friction for the bonding between the bonding surface 13 and the bonding block 105 and improve the stability between the bonding surface 13 and the bonding block 105.

[0031] Working principle: When measuring costs on engineering drawings, the staff can place this device on the drawings and measure data on the drawings under the action of the first measuring surface 8 or the second measuring surface 9. Since the first measuring surface 8 and the second measuring surface 9 have different proportions, it can be applied to different drawing scales. When measuring angles or drawing arcs, the support foot 2 and the counterweight 3 can be made to fit against the surface of the drawing, and under the action of the counterweight 3, the device can be stably placed on the drawing.

[0032] Then, with the assistance of the rotating shaft 4, the connecting block 5 can drive the ruler 6 to rotate, and with the assistance of the observation line 7, the angle to be measured can be observed.

[0033] When drawing an arc, the operator can rotate the mating block 105 according to the drawing length. Then, under the meshing of the thread body 104 and the mating block 105, the mating block 105 moves away from the mating surface 13, and the placement block 101 can be moved. With the length support of the ruler 6 and the protractor 1, the placement block 101 can be flexibly placed in the designated position. Then, the mating block 105 is used again to make the drawing mechanism 10 stop stably in the designated position. Since the placement block 101 is a hollow cone, the corresponding arc can be drawn with the rotating shaft 4 as the center using the appropriate tools.
