[0002] A geological compass is an indispensable tool for geological and mineral exploration. It typically includes components such as a magnetic needle, a graduated dial, an inclinometer, and a level.

[0003] When conducting geological exploration in the field, a geological compass, magnifying glass, and engraving knife are all essential auxiliary tools. However, if these tools are stored haphazardly in a backpack, the relatively small size of the magnifying glass and engraving knife makes them prone to being missed or lost. Although some patent documents mention designing a special cavity within the geological compass for storing the magnifying glass, this design does not achieve an effective connection or fixation between the magnifying glass and the geological compass. Therefore, the magnifying glass still faces the problem of being missed or lost. Utility Model Content

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] To address the technical problem that existing geological compasses for geological and mineral exploration cannot integrate a magnifying glass and a carving knife, leading to the easy omission or loss of small tools such as magnifying glasses and carving knives, this utility model provides a geological compass for geological and mineral exploration that can integrate a magnifying glass and a carving knife, thereby avoiding the omission or loss of small tools.

[0032] Please see Figures 1-8 , Figure 1 This is a schematic diagram of the structure of a geological compass for geological and mineral exploration in one embodiment of the present invention. The geological compass for geological and mineral exploration includes a compass body 1, a cover 2, a magnifying glass assembly 3, and a carving knife assembly 4.

[0033] The cover 2 is hinged to the compass body 1 and is used to cover the compass body 1. A first notch 21 and a second notch 22 are provided on the side wall of the cover 2.

[0034] The magnifying glass assembly 3 includes a first groove 31, a first slider 32, and a convex lens 33. The first groove 31 is fixed inside the cover 2. The first slider 32 is slidably disposed inside the first groove 31. The convex lens 33 is connected to the first slider 32 and can slide out along the first notch 21.

[0035] The engraving tool assembly 4 includes a second slide groove 41, a second slider 42, and a blade 43. The second slide groove 41 is fixed inside the cover 2, the second slider 42 is slidably disposed inside the second slide groove 41, and the blade 43 is fixed to the second slider 42 and can slide out along the second notch 22.

[0036] When using the compass for geological surveying, the user can open the cover 2 to expose the scale and pointer on the compass body 1 for direction or angle measurement. When the user needs to magnify the compass scale or observe details of a geological sample, the first slider 32 can be slid along the first groove 31, causing the convex lens 33 to slide out of the cover 2 along the first notch 21. This allows the user to observe the desired content more clearly through the convex lens 33. After use, the user can slide the convex lens 33 back into the cover 2 in the opposite direction for carrying and storage. When the user needs to mark or engrave on a geological sample, the second slider 42 can be slid along the second groove 41, causing the blade 43 to slide out of the cover 2 along the second notch 22. This allows the user to use the blade 43 for necessary marking or engraving operations. After use, the blade 43 should also be slid back into the cover 2 in the opposite direction for safety and ease of carrying.

[0037] This invention relates to a geological compass for geological and mineral exploration, integrating a magnifying glass and a carving knife into the cover, achieving a multi-functional design. This design not only improves the practicality of the geological compass but also reduces the need for users to carry additional tools. Because both the magnifying glass and carving knife components are designed within the cover and extend and retract via a sliding mechanism, the overall structure of the geological compass is more compact and lightweight. When not in use, both the magnifying glass and carving knife components can be retracted into the cover, preventing the loss or misplacement of blades or convex lenses.

[0038] In one embodiment, please refer to Figures 1-8 The magnifying glass assembly 3 further includes a first support plate 34, a second support plate 35, and a first hinge 36. One end of the first support plate 34 is fixed to the first slider 32. One end of the second support plate 35 is hinged to the other end of the first support plate 34 via the first hinge 36. The other end of the second support plate 35 is fixedly connected to the convex lens 33. In actual use, the user first smoothly pulls the first slider 32 to the outermost position of the first slide groove 31. Then, the user can use the flexible rotation of the first hinge 36 to flip the second support plate 35 relative to the first support plate 34 until the two are aligned in a straight line. This design cleverly increases the overall extension length of the second support plate 35 and the first support plate 34, allowing the convex lens 33 to be as far away from the compass body 1 as possible. This design not only provides the user with a wider field of view but also effectively avoids any interference that the compass body 1 may cause to the convex lens 33 during use, thereby ensuring that the user can obtain a clearer and more accurate observation effect through the convex lens 33.

[0039] In one embodiment, please refer to Figures 1-7The inner sidewall of the first sliding groove 31 is provided with a first limiting hole 311 and a second limiting hole 312. The first slider 32 includes a first sliding housing 321, a first fixed cylinder 322, a first moving block 323, a first locking block 324, and a first elastic element 325. The first sliding housing 321 is slidably disposed in the first sliding groove 31 and fixedly connected to one end of the first support plate 34. A first clearance hole is provided on the sidewall of the first sliding housing 321. The first fixed cylinder 322 is fixed in the first sliding housing 321 and is coaxially disposed with the first clearance hole. The first moving block 323 is slidably disposed in the first fixed cylinder 322. One end of the first locking block 324 is fixed to the first moving block 323, and the other end of the first locking block 324 has a first spherical protrusion 3241. When the first slider 32 is located at one end of the first groove 31 (e.g., at the innermost end of the first groove 31), the first spherical protrusion 3241 can extend into the first limiting hole 311 under the action of the first elastic member 325, restricting the first slider 32 from continuing to slide spontaneously; when the first slider 32 is located at the other end of the first groove 31 (e.g., at the outermost end of the first groove 31), the first spherical protrusion 3241 extends into the second limiting hole 312, restricting the first slider 32 from continuing to slide spontaneously. The function of the first elastic member 325 is to apply pressure to the first locking block 324, so that the first spherical protrusion 3241 is held in the first limiting hole 311 or the second limiting hole 312. One end of the first elastic member 325 is connected to the first fixed cylinder 322, and the other end of the first elastic member 325 is connected to the first moving block 323. This design ensures that the first slider 32 will not move spontaneously when it is located at the innermost and outermost ends of the first groove 31. At the same time, since the outer end of the first spherical protrusion 3241 adopts a spherical design, the user only needs to move the first support plate 34 or the second support plate 35 to drive the first slider 32 to move, so that the first spherical protrusion 3241 disengages from the first limiting hole 311 or the second limiting hole 312, which improves the convenience of use.

[0040] In one embodiment, please refer to Figures 1-7 The inner wall of the first sliding groove 31 is also provided with a first anti-detachment groove 313 to prevent the first sliding housing 321 from detaching from the first sliding groove 31 during sliding. The outer wall of the first sliding housing 321 is formed with a first anti-detachment protrusion that cooperates with the first anti-detachment groove 313. The first anti-detachment protrusion is slidably disposed in the first anti-detachment groove 313. During the sliding of the first slider, the first anti-detachment protrusion will always slide in the first anti-detachment groove 313, thereby preventing the first slider from detaching from the first sliding groove during sliding.

[0041] In one embodiment, please refer to Figures 1-7The inner wall of the second slide groove 41 is provided with a third limiting hole 411 and a fourth limiting hole 412. The structure of the second slider 42 is similar to that of the first slider 32, including a second sliding housing 421, a second fixed cylinder 422, a second moving block 423, a second locking block 424, and a second elastic element 425. The second sliding housing 421 is slidably disposed in the second slide groove 41 and fixedly connected to the blade 43. The other end of the second locking block 424 has a second spherical protrusion 4241. When the second slider 42 is located at one end of the second slide groove 41, the second spherical protrusion 4241 extends into the third limiting hole 411; when the second slider 42 is located at the other end of the second slide groove 41, the second spherical protrusion 4241 extends into the fourth limiting hole 412. One end of the second elastic member 425 is connected to the second fixed cylinder 422, and the other end of the second elastic member 425 is connected to the second moving block 423. The working process and technical effect of the second slider 42 are similar to those of the first slider 32, and will not be described in detail here.

[0042] In one embodiment, please refer to Figures 1-7 The inner sidewall of the second sliding groove 41 is also provided with a second anti-detachment groove 413 to prevent the second sliding housing 421 from detaching from the second sliding groove 41 during sliding. The outer sidewall of the second sliding housing 421 is formed with a second anti-detachment protrusion that cooperates with the second anti-detachment groove 413. The second anti-detachment protrusion is slidably disposed in the second anti-detachment groove 413 to prevent the second sliding housing 421 from detaching from the second sliding groove 41 during sliding.

[0043] In one embodiment, please refer to Figures 1-7 The inner wall of the second sliding groove 41 is also provided with a locking screw hole 414 communicating with the fourth limiting hole 412. The second spherical protrusion 4241 is provided with a positioning hole 42411 for cooperating with the locking rod 45 to lock the position of the second slider 42. The engraving knife assembly 4 also includes a locking screw 44 and a locking rod 45. The locking screw 44 is threaded into the locking screw hole 414. One end of the locking rod 45 is coaxially fixed to the locking screw 44, and the other end of the locking rod 45 is used to insert into the positioning hole 42411 to lock the position of the second slider 42. When the blade 43 needs to be moved to the outermost position, the second spherical protrusion 4241 can be pushed into the fourth limiting hole 412 by the second elastic element 425. At this time, the user can rotate the locking screw 44 to insert the locking rod 45 into the positioning hole 42411 on the second spherical protrusion 4241, thereby locking the position of the second slider 42. After use, the locking screw 44 can be turned in the opposite direction to release the lock. This design prevents the blade 43 from retracting or wobbling during the engraving process, improving the accuracy and stability of the engraving.

[0044] In one embodiment, please refer to Figures 5-8 The engraving tool assembly 4 also includes a lever 46, which is fixed to the blade 43 for convenient movement of the blade 43.

[0045] In one embodiment, please refer to Figure 1 and Figure 2 The geological compass for geological and mineral exploration also includes a reflector assembly 5, used in conjunction with the compass body 1 for functions such as direction positioning. The reflector assembly 5 includes a frame 51 and a reflector 52. One end of the frame 51 is hinged to the cover 2 via a second hinge 53, allowing the reflector 52 to be adjusted at a certain angle relative to the cover 2. The reflector 52 is fixed inside the frame 51 and located above the first slide groove 31 and the second slide groove 41. The frame 51 is hinged to the cover 2, so that when the magnifying glass assembly or engraving knife assembly below the frame 51 needs to be used, the frame 51 can be flipped up to access these tools without obstruction. Preferably, the second hinge 53 is a damping pivot, allowing the frame 51 to remain at any rotation angle for convenient use. The first hinge 36 can also be a damping pivot.

[0046] In one embodiment, please refer to Figure 1 The compass body 1 is equipped with a magnetic needle 11, a scale 12 and a level 13, which are used for geological exploration work such as direction measurement, angle measurement and level calibration.

[0047] To better understand this utility model, the following is combined with... Figures 1 to 8 The technical solution of this utility model is described in detail below: When using the compass for geological surveying, the user can open the cover 2 to expose the scale and pointer on the compass body 1 for direction or angle measurement. When the user needs to magnify the compass scale or observe details of a geological sample, the frame 51 can be flipped up, and the first slider 32 can be slid along the first groove 31, causing the convex lens 33 to slide out of the cover 2 along the first notch 21. This allows the user to observe the desired content more clearly through the convex lens 33. After use, the user can slide the convex lens 33 back into the cover 2 in the opposite direction for carrying and storage. When the user needs to mark or engrave on a geological sample, the second slider 42 can be slid along the second groove 41, causing the blade 43 to slide out of the cover 2 along the second notch 22. This allows the user to use the blade 43 for necessary marking or engraving operations. After use, the blade 43 should also be slid back into the cover 2 in the opposite direction to ensure safety and ease of carrying.

[0048] This invention relates to a geological compass for geological and mineral exploration, integrating a magnifying glass and a carving knife into the cover, achieving a multi-functional design. This design not only improves the practicality of the geological compass but also reduces the need for users to carry additional tools. Because both the magnifying glass and carving knife components are designed within the cover and extend and retract via a sliding mechanism, the overall structure of the geological compass is more compact and lightweight. When not in use, both the magnifying glass and carving knife components can be retracted into the cover, preventing the loss or misplacement of blades or convex lenses.

[0049] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
