Description

Technical Field

[0001] The utility model relates to the technical field of hole measurement, in particular to an angle gauge used for hole position lead-out measurement. Background Art

[0002] In the process of steel production in steel mills, workers usually measure the angle and position manually and then fix the hole position at that point. This method is usually time-consuming and labor-intensive, and manual measurement has errors.

[0003] After searching, the Chinese patent with authorization announcement number CN213714131U discloses a measuring ruler for assisting in checking the hole positions of sample circular holes. The measuring ruler is a transparent, square, 1mm thick thin plate-like part. A right-angled triangle notch with a hypotenuse of 45° is opened in the middle of the measuring ruler. The hypotenuse is the working edge, and the opposite right-angled edge is the vertical reference edge. A rectangular opening is opened at the bottom of the hypotenuse. The long side of the rectangular opening is perpendicular to the vertical reference edge and is the horizontal reference edge. The working edge and the horizontal reference edge are marked with corresponding upper and lower scales, which can be applicable to circular holes of various apertures.

[0004] Based on the above search combined with the existing technology, we found that;

[0005] The above patent can only be used for plane measurement and cannot be used for measurement based on component angles. At present, the hole size measurement of steel structures in China is carried out by using a ruler and a protractor to draw hole measurement auxiliary lines step by step onto the cover plate. The hole line accuracy deviation is large, so there are certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes an angle gauge for hole position lead-out measurement, which can be adjusted according to the angle and thickness of the steel. The device is fixed by a fixing knob to ensure that the device fits the steel. In addition, the web distance ruler and the cover plate measuring ruler are used to improve the measurement accuracy and reduce errors.

[0007] The technical solution to achieve the purpose of the utility model is: a protractor ruler for hole position lead-out measurement, comprising a web ruler, a web distance measuring ruler fixedly installed near the bottom of the web ruler, a first leg fixedly installed near the end of the web ruler, a second leg rotatably installed on the end of the first leg through a movable shaft, a transverse movable rod fixedly installed on one side of the second leg, a longitudinal movable rod slidably installed on the transverse movable rod, and a first fixed knob connected between the transverse movable rod and the longitudinal movable rod by a thread.

[0008] Preferably, a cover plate ruler is slidably installed inside the longitudinal movable rod, and a cover plate distance measuring ruler is fixedly installed near the end of the cover plate ruler.

[0009] Preferably, a second fixing knob is threadedly connected between the longitudinal movable rod and the cover plate ruler, and a third fixing knob is threadedly connected between the first leg and the second leg.

[0010] Preferably, an I-shaped steel is provided between the transverse movable rod and the cover plate ruler, the side surface of the web plate ruler is in contact with the inner wall of the I-shaped steel, and a plurality of groups of circular holes are equidistantly provided on the I-shaped steel.

[0011] Preferably, a reinforcing rod one is fixedly installed between the web ruler near the end and the first leg, and a reinforcing rod two is fixedly installed between the transverse movable rod and the second leg.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] First: The utility model is a protractor ruler used for hole position lead-out measurement, in which leg one and leg two are connected by a movable shaft, connected and fixed with a transverse movable rod, and the transverse movable rod and the web ruler can adjust the measuring angle according to the third fixed knob, thereby improving the practicality and flexibility of the protractor ruler, in addition, the measuring position can be adjusted according to the thickness of the steel through the longitudinal movable rod, the cover plate ruler and the transverse movable rod, thereby improving the practicality of the device, and further, the accuracy of the device in measuring the hole position is improved through the web distance measuring ruler and the cover plate distance measuring ruler.

[0014] Secondly: After each device is fixedly installed, the utility model installs a fixed knob to ensure the stability of measurement, facilitates the accurate measurement of the hole position, and effectively avoids the error caused by human labor. In addition, the reinforcing rods 1 and 2 installed on a pair of legs improve the structural strength of the device and extend its service life.

[0015] The present invention solves the problem that the above-mentioned patent can only be used for plane measurement and cannot measure according to the angle of the component. At present, the hole size measurement of steel structure in China is carried out by using a ruler and a protractor to draw the hole measurement auxiliary lines step by step onto the cover plate, which leads to large deviation in the accuracy of the hole line.
