Description

Technical Field

[0001] The utility model relates to the technical field related to surveying rulers, in particular to a surveying ruler for engineering cost. Background Art

[0002] Project cost refers to the total cost of a project, and its core content is investment estimation, design budget, revised budget, construction drawing budget, project settlement, final settlement, etc. In the project cost industry, it is often necessary to measure the drawings to obtain some data, or draw drawings based on the measuring ruler. The measuring ruler is a tool used to measure length, width and other dimensions.

[0003] The utility model patent with announcement number CN220136180U discloses a surveying ruler for engineering cost drawings, which belongs to the technical field related to surveying rulers. It solves the problem that in the prior art, a surveying ruler is needed to draw engineering cost drawings, but some drawings need to be used in combination with two surveying rulers, that is, a single surveying ruler is placed on another surveying ruler at a certain angle to form a certain angle, and when different surveying rulers maintain a certain angle, they are easily accidentally touched, resulting in a certain position deviation of the adjusted angle. When people use them again, they need to adjust the two surveying rulers again to form the previous angle, but the operation of repeatedly adjusting the angle will increase a certain operation time, reducing the work efficiency of people drawing engineering cost drawings. The main surveying ruler and the main surveying ruler are used together. A fixed inner cavity is provided inside the ruler, a No. 2 slide groove is provided in the middle of the top of the inner wall of the fixed inner cavity, a sliding part is movably installed on the upper surface of the main surveying ruler, the middle of the bottom end of the sliding part extends to the inside of the fixed inner cavity where a gear is rotatably installed, a knob is welded on the top of the gear through the upper surface of the sliding part, and a fixed rack is fixedly installed in the middle of the bottom end of the inner wall of the fixed inner cavity near the gear; this application forms different angles by rotating the main surveying ruler in conjunction with the auxiliary surveying ruler, thereby achieving a more efficient effect in drawing engineering cost drawings, improving the stability of the main surveying ruler and the auxiliary surveying ruler when they form an angle with each other, solving the problem of angle deviation or position offset caused by accidental touch of the main surveying ruler and the auxiliary surveying ruler after adjusting the angle, and improving the overall accuracy of the main surveying ruler and the auxiliary surveying ruler when used together.

The ruler does not have the function of measuring the corners of the building, which makes it inconvenient for the user to measure the corners of the building. Then, the limit knob 14 is rotated, and the limit knob 14 drives the second rotating shaft 8 to rotate. The second rotating shaft 8 drives the first screw 15. The first screw 15 rotates while driving the nut 16. The nut 16 moves toward the limit knob 14 through the cooperation of the limit ring 17, and then the third linkage rod 9 and the fourth linkage rod 10 are squeezed and limited through the cooperation of the nut 16 and the limit knob 14, and then the third linkage rod 9 and the fourth linkage rod 10 are limited and fixed, which can avoid the situation where the angle changes.

[0036] When surveying an arc line, the user can adjust the sliding sleeve 7 according to the radius of the arc line to be drawn, and then lean the back plate 24 against the edge of the table, and then rotate the ruler 1, the ruler 1 drives the arc plate 22, the ruler 1 and the arc plate 22 rotate with the fifth rotating shaft 25 as the center, and then survey the arc line.
