Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a separable engineering measuring ruler. Background Art

[0002] Civil engineering is a general term for the science and technology of building various types of land engineering facilities. It refers to the materials and equipment used, and the technical activities such as surveying, design, construction, maintenance, and repair carried out, as well as the objects of engineering construction. In the process of civil engineering construction, various measuring rulers are often needed to measure various data.

[0003] At present, the existing civil engineering measuring rulers can meet some measurement needs, but there are still the following defects: 1. Most measuring rulers have a single function. In order to measure different data, it is often necessary to carry measuring rulers with various functions; 2. Some measuring rulers can only measure short distances and are less practical. For this reason, we propose a detachable engineering measuring ruler. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art that most measuring rulers have a single function, and in order to measure different data, it is often necessary to carry measuring rulers with various functions, and some measuring rulers can only measure short distances, which has poor practicality, and a separable engineering measuring ruler is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A separable engineering measuring ruler comprises a main ruler and a sub-rule, wherein rotating shafts are fixedly mounted on the inner walls on both sides of the main ruler, two engaging grooves are provided on the circumferential outer walls of the two rotating shafts, limiting plates are fixedly mounted on the ends of the two rotating shafts close to each other, and the same leather measuring tape is rotatably mounted on the sides of the two limiting plates close to each other.

[0007] Two rotating cards are fixedly installed on one side of the secondary ruler, and a second engaging groove is provided at the bottom of the two rotating cards, and the second engaging groove is adapted to the first engaging groove. The two rotating cards are engaged and connected with two rotating shafts through the cooperation of the second engaging groove and the first engaging groove. When the rotating shaft is located in the semicircular part of the second engaging groove, the rotating card can rotate around the rotating shaft as the center.

[0008] One end of the leather measuring tape is fixedly connected to one side of the secondary ruler.

[0009] Preferably, a same baffle is rotatably mounted on one side of the bottom of the inner walls on both sides of the main scale, and a limit block is fixedly mounted on one side of the top of the baffle.

[0010] Preferably, connecting tenons are fixedly installed on both sides of the limit block, and connecting tenons are fixedly installed on the inner walls on both sides of the main ruler, and the connecting tenons are matched with the connecting tenons.

[0011] Preferably, angle dials made of transparent material are embedded and installed on both sides of the main ruler, and two horizontal dials made of transparent material are embedded and installed on both sides of the two rotating cards.

[0012] Preferably, a first level is fixedly mounted on one side of the main ruler, and a second level is embeddedly mounted on one side of the secondary ruler.

[0013] Preferably, a magnet is fixedly mounted on the other side of the main scale.

[0014] In the present application, when people need to measure long distances, they first open the baffle, then rotate the secondary ruler so that the second engaging slot and the first engaging slot reach an appropriate angle, take out the secondary ruler and close the baffle, move the secondary ruler and pull the leather tape measure, then determine that the main ruler is in a horizontal position through the first level meter, determine that the secondary ruler is in a horizontal position through the second level meter, determine that the tape measure of the leather tape measure is in a tight and horizontal position through the tape measure of the leather tape measure and the angle dial and the horizontal dial, and finally calculate the measurement data through the scales on the main ruler, the secondary ruler and the leather tape measure. When people finish measuring and want to store it, they first open the baffle, then make the second engaging slot and the first engaging slot reach an appropriate angle and engage them, then rotate the secondary ruler and close the baffle, and finally complete the storage by adsorbing it on the tool box through the magnet. When people need to measure an angle, they first rotate the secondary ruler, then place the side of the main ruler and the secondary ruler close to each other on both sides of the angle to be measured, and read the angle data by cooperating with the horizontal dial and the angle dial.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Through the coordination of the main ruler, the auxiliary ruler and the tape measure, the main ruler and the auxiliary ruler can be separated by the engagement connection of the first engagement groove and the second engagement groove to achieve long-distance measurement. The first level, the second level, the horizontal dial and the tape measure can also be used to ensure that the main ruler and the auxiliary ruler are on the same horizontal line during measurement, thereby improving the accuracy of the measurement data.

[0017] 2. Through the setting of the angle dial, the horizontal dial and the two spirit levels, people can use the measuring ruler to conveniently perform angle and horizontal measurements, thereby improving the functionality and practicality of the measuring ruler.

[0018] 3. Through the setting of magnets, people can adsorb the measuring ruler on metal objects when it is not in use, so that it can be easily taken at any time.

[0019] In the utility model, the measuring ruler can be separated according to the situation, the measuring distance can be extended, the horizontal position can be ensured, the accuracy of the measured data can be improved, a variety of data measurements can be performed and flexibly fixed, and the functionality and practicality of the measuring ruler are improved.
