In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a multifunctional geological compass, including an upper cover and a lower cover, the upper cover and the lower cover are hinged by a rotating shaft, and the feature is that: A reflective mirror is embedded, a magnifying glass rotatably connected to the rotating shaft is arranged on the inner side of the upper cover, a dial, a magnetic needle capable of rotating around the center of the dial and tube levels located on both sides of the dial are embedded in the lower cover. One end of the lower cover is provided with an aiming target plate, and a detachable hardness pen is installed on the aiming target plate, and the scale on the dial is along the counterclockwise direction from 0° to 360° split evenly.

The above-mentioned multifunctional geological compass is characterized in that the magnifying glass is rotatably connected to the rotating shaft through the connecting piece.

The above-mentioned multifunctional geological compass is characterized in that: the number of the hardness pens is four.

The above-mentioned multifunctional geological compass is characterized in that: the straight line where the 0° marking point and the 180° marking point on the dial are located is perpendicular to the axis of the rotating shaft and bisects the axis of the rotating shaft.

The above-mentioned multifunctional geological compass is characterized in that: the surface of the scale line on the dial and the surfaces at both ends of the magnetic needle are coated with a fluorescent layer.

Compared with the prior art, the utility model has the following advantages:

1. The utility model is simple in structure, reasonable in design, easy to use and operate, simple in manufacturing process, and can effectively solve practical problems such as inconvenient operation in special places such as narrow and dark spaces, and unreliable test results.

2. The utility model integrates the basic functions of the geological compass with the functions of testing tools such as a magnifying glass and a hardness pen. On the basis of not affecting the original functions of the geological compass, it satisfies the needs of geologists for further investigation of rocks, minerals, and fossils in the field. It has good practical value and is suitable for popularization and application.

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.

detailed description

A multi-functional geological compass as shown in Figure 1 includes an upper cover 1 and a lower cover 2, the upper cover 1 and the lower cover 2 are hinged through a rotating shaft 3, and the upper cover 1 is embedded with a reflector 4, The inner side of the upper cover 1 is provided with a magnifying glass 5 that is rotatably connected to the rotating shaft 3, and the lower cover 2 is embedded with a dial 6, a magnetic needle 9 that can rotate around the center of the dial 6, and a magnetic needle 9 located on both sides of the dial 6, respectively. Tube level 7 and circular level 8, one end of the lower cover 2 is provided with an aiming target plate 10, and a detachable hardness pen 11 is rotatably mounted on the aiming target plate 10, and the scale on the dial 6 is along the The counterclockwise direction is equally divided according to 0°～360°.

In this embodiment, the magnifying glass 5 is rotatably connected to the rotating shaft 3 through the connecting piece 12 , and the magnifying glass 5 is rotated so that it can overlap with the reflective mirror 4 or the dial 8 .

In this embodiment, the number of hardness pens 11 is 4, and hardness pens with different hardness values can be selected for preliminary identification of the hardness range of rocks or minerals.

In this embodiment, the straight line where the 0° marking point and the 180° marking point on the dial 6 are perpendicular to the axis of the rotating shaft 3 and bisects the axis of the rotating shaft 3 .

In this embodiment, the surface of the scale line on the dial 6 and the surfaces at both ends of the magnetic needle 9 are coated with a fluorescent layer, which is convenient for use in an environment with insufficient light.

During ordinary measurement, rotate the magnifying glass 5 so that it coincides with the reflector 4, which is used to measure the occurrence of rock formations in a small and dark space, and rotate the magnifying glass 5 so that it coincides with the dial 8, so that the scale marks on the dial 8 can be checked. and the two ends of the magnetic needle play a magnifying effect, so that the reading is clear and convenient for the staff to observe; during field identification, rotate the magnifying glass 5 to a suitable angle, and can observe the target mineral more carefully, and then aim at the hardness pen 11 on the target plate 10 Rotate to an appropriate angle, mark the target mineral to estimate its hardness value, and according to the actual situation, you can choose to install a hardness pen with different hardness values to mark and determine the hardness range of the target mineral, providing useful and reliable information for identification work.
