Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a geological compass used for geological and mineral exploration. Background Art

[0002] The geological compass, also known as a "pocket theodolite," is an indispensable tool for geological and mineral exploration. It can be used to determine direction, the location of observation points, and the spatial position of any observation surface (such as the spatial position of rock layers, fold axes, fault planes, joint planes, and other structural surfaces), as well as to determine various structural elements of igneous rocks and the occurrence of ore bodies.

[0003] The copper wire in a geological compass is used to balance the vertical component of the Earth's magnetic force, ensuring that the pointer can rotate freely horizontally, thereby improving the compass's measurement accuracy. However, existing geological compasses have certain drawbacks when in use. Adjusting or repositioning the copper wire requires opening the lens on the compass. This makes it difficult to directly open the lens, making it difficult to quickly disassemble and ensuring the stability of the lens after subsequent installation.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1:

[0025] This embodiment is used to solve the problems of existing geological compasses, such as difficulty in directly opening the lens on the compass, difficulty in achieving rapid disassembly, and difficulty in ensuring the stability of the lens after subsequent installation.

[0026] See also Figure 1 - Figure 5 As shown, this embodiment is a geological compass for geological and mineral exploration, including a compass body 1, a cover plate 2 is rotatably connected to the upper surface of the compass body 1, and an aiming plate 7 is rotatably connected to the side of the compass body 1 away from the cover plate 2. A mounting groove 14 is provided at the center of the compass body 1, and a magnetic needle 8 is rotatably connected to the center of the mounting groove 14. A copper wire 9 is sleeved on the magnetic needle 8. An annular mounting groove 2 is provided on the inner wall of the mounting groove 14 near the upper surface of the compass body 1, and a lens 3 is placed in the mounting groove 2. A quick separation mechanism is provided in the compass body 1, and the quick separation mechanism includes a mounting cavity 15 provided in the compass body 1, and a lifting bar 11 is rotatably connected to the inner wall of the surface of the mounting cavity 15. The lifting bar 11 passes through The mounting groove 14 is against the lower surface of the lens 3. When the lifting bar 11 rotates, one end of the lifting bar 11 is tilted, pushing the lens 3 to disengage from the mounting groove 2 14. A pushing block 16 is provided in the mounting cavity 15, which is against the upper surface of the lifting bar 11. The pushing block 16 is against the other end of the lifting bar 11. When the pushing block 16 moves vertically downward, the other end can be tilted. The upper surface of the pushing block 16 is fixedly connected to a pressing block 12 that passes through the compass body 1. By pressing the pressing block 12, the pushing block 16 is moved vertically downward, and the end of the lifting bar 11 against the lens 3 can be tilted, so that the lens 3 can be quickly disassembled, which facilitates the replacement of the copper wire 9 on the magnetic needle 8 in the mounting groove 14.

[0027] The lower surface of the push block 16 and the bottom of the installation cavity 15 are fixedly connected with a positioning column 18. The positioning column 18 facilitates the subsequent installation of the spring 17. A spring 17 is sleeved between the two positioning columns 18. The spring 17 and the positioning column 18 are abutted against each other, which can realize automatic reset of the positioning column 18, thereby resetting the push block 16 fixedly connected to the positioning column 18.

[0028] A movable cavity is provided on the surface of the second mounting groove 14, extending into the mounting cavity 15 and communicating with the mounting cavity 15. The movable cavity is provided for the lifting bar 11 to swing in the movable cavity. The inner wall of the movable cavity of the second mounting groove 14 is fixedly connected with a rotating shaft that passes through the lifting bar 11 and is rotatably connected to the lifting bar 11, so that the lifting bar 11 can swing around the center line of the rotating shaft.

[0029] The outer wall of the pressing block 12 located in the installation cavity 15 is fixedly connected with a stopper. The pressing block 12 passes through the compass body 1 and is vertically slidably connected to the compass body 1. The vertical height of the pressing block 12 is limited by setting the stopper to prevent the top of the pressing block 12 from contacting the reflector on the cover 2.

[0030] The bottom wall of the compass body 1 is rotatably connected to a connector 5 on both sides through a pin shaft, which has a certain buffering effect. The end of the connector 5 away from the compass body 1 is fixedly connected to a strap 6. The two straps 6 are provided with Velcro on the surface so that the length can be adjusted as needed to ensure that the compass body 1 can fit tightly on the wrist for easy carrying.

[0031] Example 2:

[0032] This embodiment is used to solve the problem of how to further ensure the stability of the lens.

[0033] See also Figure 1 、 Figure 5 As shown, a geological compass for geological and mineral exploration of this embodiment has an eccentric column 10 fixedly connected to the upper surface of the compass body 1 near the lens 3, and a turntable 13 is inserted through the eccentric column 10 and rotatably connected thereto; when the turntable 13 is rotated, the turntable 13 can block the lens 3 located in the mounting groove 14 as the turntable 13 rotates, thereby preventing the lens 3 from easily detaching from the mounting groove 14.

[0034] Combining Example 1 and Example 2

[0035] By setting up a quick separation mechanism, the lens can be easily disassembled, and then the copper wire 9 on the magnetic needle 8 can be maintained and replaced, which greatly simplifies the adjustment process of the compass body 1 and improves work efficiency. Through the coordinated use of the spring 17 and the positioning column 18, the automatic resetting function of the push block 16 is realized. The turntable 13 is rotated. As the turntable 13 rotates, the lens 3 can be shielded by the turntable 13 on the lens 3 located in the installation groove 14 to prevent the lens 3 from easily detaching from the installation groove 14, which can further ensure the stability of the lens 3. It has the advantages of good stability, easy maintenance and replacement, strong practicality and simple operation, and can meet the needs of geological and mineral exploration for high-precision measurement.

[0036] like Figure 1 - Figure 5 As shown, the working process and principle of the utility model are as follows:

[0037] Step 1: Undo the compass body 1 that is sleeved on the wrist, open the cover 2, rotate the turntable 13 on the compass body 1 to separate the turntable 13 from the edge of the lens 3, press the pressing block 12 on the compass body 1, and move the pushing block 16 fixedly connected to the pressing block 12 vertically downward. The pushing block 16 moves downward and presses the lifting bar 11, so that the lifting bar 11 is tilted at one end close to the lens 3. The lifting bar 11 pushes the lens 3 downward, making it easier to separate the lens 3 from the mounting groove 2 14 on the mounting groove 1 4, thereby facilitating the quick removal of the lens 3. Then, the copper wire 9 jin on the magnetic needle 8 is removed and sleeved on the other end of the magnetic needle 8.

[0038] Step 2: Place the lens 3 into the corresponding mounting groove 2 14 . The lens 3 presses the lifting bar 11 to reset. The pressing block 12 automatically resets under the action of the spring 17 . Then, rotate the turntable 13 to reset the edge of the turntable 13 to achieve positioning of the lens 3 .
