Description

Technical Field

[0001] This invention relates to the field of geological compass technology, specifically a geological compass with a magnifying glass function. Background Technology

[0002] Geological compasses are essential tools for identifying directions and determining locations during geological exploration. However, traditional geological compasses have certain limitations. For example, in situations with insufficient light or limited vision in the field, their fine graduations are difficult to read accurately. Furthermore, details such as rock textures and mineral crystal structures may be difficult to discern with the naked eye, affecting accurate judgment and analysis. Additionally, traditional compasses have limited functionality, requiring geologists to carry additional tools such as magnifying glasses to observe geological specimens and maps, increasing their workload in the field and making the coordination of tools inconvenient. To address these issues, a magnifying glass function has been introduced into geological compasses. This allows geologists to conveniently observe relevant details while using the compass for measurements, improving work efficiency, reducing operational errors, and alleviating the burden of carrying multiple tools.

[0003] In the prior art, such as the geological compass described in Chinese Patent No. CN220568147U, a base shell is included. A groove is formed on the upper surface of the base shell, and a scale is fixedly installed on the bottom surface of the groove. A protective mechanism is provided on the side of the base shell, and a support mechanism is provided on the bottom surface of the base shell. The protective mechanism includes a rotating unit, a sealing unit, and a fixing unit. The rotating unit includes a rotating shaft groove, a rotating shaft, and a top cover. The sealing unit includes a reflector, a sealing ring, and a protective ring. The fixing unit includes a locking post, a locking block, and a locking groove. This geological compass, by setting up a support mechanism with a sliding groove and a slider, facilitates disassembly and use. A shock-absorbing spring prevents vibration. A lifting column and a hydraulic cylinder facilitate height adjustment. The sealing ring, after the top cover is closed, allows the outer surface of the sealing ring to be fixedly connected to the inner wall of the groove, forming a sealed space to prevent water ingress.

[0004] While the aforementioned patents can support the geological compass, they still have some problems. The fixed positions of the support columns may reduce stability, and uneven ground may affect the normal use of the compass. Therefore, this invention provides a geological compass with a magnifying glass function. Summary of the Invention

[0016] Beneficial effects

[0017] This invention provides a geological compass with a magnifying glass function. Compared with the prior art, it has the following advantages:

[0018] Beneficial effects:

[0019] 1. This geological compass with a magnifying glass function, when used on the ground, improves its stability by rotating the rotating shaft at the bottom of the mounting cylinder and the second rotating plate. The rotating shaft drives the gear disc to rotate synchronously. The gear disc, through meshing with a bevel gear, transmits rotational power to the threaded screw, causing the threaded screw to rotate. As the threaded screw rotates, the moving slider moves along the axial direction of the threaded screw within a groove, thereby causing the moving plate and the supporting base to expand or retract laterally. Adjusting the span of the supporting base enhances the compass's stability, ensuring stable placement on the ground.

[0020] 2. This geological compass with a magnifying glass function allows the operator to adjust the compass level to suit different terrains by rotating the knob at the top of the screw. Rotating the screw, through threaded transmission, drives the support base to move up and down along the screw's axial direction. This allows for fine-tuning of the support height according to the ground's flatness, ensuring the compass remains level and providing a foundation for accurate measurements. For example, on uneven surfaces such as slopes, raising or lowering the support base at different positions restores the compass to a level position.

[0021] 3. This geological compass with a magnifying glass function allows the magnifying glass body to be removed from its storage slot when needed. When the magnifying glass body is in use, the third rotating plate drives the bidirectional screw to rotate. The bidirectional screw, through two connecting sliders, causes two protective round shells to open, allowing the magnifying glass body to be removed for use. When the magnifying glass body is not in use, the bidirectional screw can be rotated in the opposite direction, causing the two protective round shells to protect and fix the magnifying glass body. The protective round shells facilitate the use of the magnifying glass body while protecting it. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides two technical solutions:

[0032] Figures 1-7 The first embodiment is shown: a geological compass with a magnifying glass function, including a bottom support component 1, and a compass component 2 is provided at the top of the bottom support component 1;

[0033] The bottom support assembly 1 includes a base plate 11. A set of sliding grooves 13 are opened through the bottom end of the base plate 11. A threaded screw 14 is rotatably installed on the inner wall of the sliding grooves 13. A circular groove 12 is opened through the top end of the base plate 11. A gear disk 110 is provided on the inner wall of the circular groove 12. A set of bevel gears 19 are meshed on the outer wall of the gear disk 110. One end of the outer wall of the threaded screw 14 is opened through the inner wall of the circular groove 12. By rotating the gear disk 110, the set of bevel gears 19 can be driven to rotate simultaneously, and the set of threaded screws 14 can be driven to rotate simultaneously, and are respectively fixedly connected to the set of bevel gears 19. A set of support chassis 17 is provided on the outer wall of the base plate 11.

[0034] The compass assembly 2 includes a mounting shell 21, on the inner wall of which a compass body 22 is fixedly mounted. A rotating cover 23 is rotatably mounted on the top of the mounting shell 21. By rotating the rotating cover 23, the compass body 22 can be exposed, thus allowing the compass body 22 to be used. A magnifying glass body 28 is provided on the top of the rotating cover 23.

[0035] The outer wall of the threaded screw 14 is threadedly connected to a movable slider 15, which is movably inserted into the inner wall of the slide groove 13. A movable plate 16 is fixedly installed on one side of the outer wall of the movable slider 15.

[0036] The top of the movable plate 16 is threaded with a rotating screw 18, and a support base 17 is fixedly installed at the bottom of the rotating screw 18. A first rotating plate is fixedly installed at the top of the rotating screw 18 to drive the rotating screw 18 to rotate. When the rotating screw 18 rotates, it can drive the support base 17 to rise and fall. By adjusting the support base 17, the device can be horizontally adjusted on different terrains. At the same time, a level bubble meter can be installed on the device to facilitate horizontal adjustment.

[0037] A mounting cylinder 111 is fixedly mounted on the base plate 11. A rotating shaft is rotatably mounted on the bottom end of the mounting cylinder 111. The top end of the rotating shaft is fixedly connected to the gear disk 110. A second rotating plate is fixedly mounted on the bottom end of the rotating shaft. The gear disk 110 can be driven to rotate through the second rotating plate and the rotating shaft.

[0038] Figures 1-7 The second embodiment is shown. The main difference from the first embodiment is that the top of the rotating cover 23 has a placement groove 27 through it, the magnifying glass body 28 is placed at the bottom of the inner wall of the placement groove 27, the top of the rotating cover 23 has an installation groove, and a bidirectional screw 29 is rotatably installed on the inner wall of the installation groove.

[0039] Two connecting sliders 210 are threadedly connected to the outer wall of the bidirectional screw 29. A protective round shell 211 is fixedly installed on one end of the outer wall of each connecting slider 210. When the bidirectional screw 29 rotates, it can drive the two connecting sliders 210 to move away from each other or closer to each other. The connecting sliders 210 can then drive the two protective round shells 211 to move closer to each other or further away. When the two protective round shells 211 are close together and closed, they can protect the magnifying glass body 28. When the two protective round shells 211 are far apart, the magnifying glass body 28 can be taken out for use. The bottom ends of the two protective round shells 211 are slidably set with the top end of the rotating cover 23.

[0040] The inner walls of the two protective round shells 211 match the outer wall of the magnifying glass body 28. When the two protective round shells 211 are closed, the magnifying glass body 28 can be fixed. One end of the outer wall of the bidirectional screw 29 passes through the outer wall of the rotating cover 23 and is fixedly installed with a third rotating plate.

[0041] The outer wall of the mounting shell 21 is rotatably mounted with a buckle 24, and the outer wall of the mounting shell 21 is fixedly mounted with a locking block 25. When the buckle 24 is engaged with the outer wall of the locking block 25, the rotating cover 23 can be fixed. The base plate 11 is fixedly connected to the mounting shell 21.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] When the compass body 22 is needed during operation, the latch 24 is rotated to disengage from the locking block 25. Then, the rotating cover 23 is opened to expose the compass body 22. During use, geologists use the scale, magnetic needle, and other components on the compass body 22 to measure geological information such as the strike and dip angle of rock strata, while also carefully observing the surrounding geological features. After completing the measurement and observation tasks, the rotating cover 23 is closed, and the latch 24 and locking block 25 are fastened together to store the compass. When the magnifying glass body 28 is needed, the third rotating plate drives the bidirectional screw 29 to rotate. The bidirectional screw 29, through two connecting sliders 210, drives the two protective shells 211 to open, allowing the magnifying glass body 28 to be taken out from the placement slot 27 for use. When the magnifying glass body 28 is not needed, the bidirectional screw 29 can be rotated in the opposite direction, causing the two protective shells 211 to protect and fix the magnifying glass body 28. The protective shells 211 facilitate the use of the magnifying glass body 28 while protecting it. When the device needs to be placed on the ground, to improve its stability, the rotating shaft at the bottom of the mounting cylinder 111 and the second rotating plate are rotated. The rotating shaft drives the gear disk 110 to rotate synchronously. The gear disk 110 transmits rotational power to the threaded screw 14 through meshing with the bevel gear 19, causing the threaded screw 14 to start rotating. As the threaded screw 14 rotates, the movable slider 15 moves axially along the threaded screw 14 within the groove 13, thereby causing the movable plate 16 and the support base 17 to expand or retract laterally. Adjusting the span of the support base 17 enhances the stability of the compass placement, ensuring stable placement on the ground. When leveling the compass to adapt to different terrains, the operator rotates the knob at the top of the screw 18. Rotating the screw 18, through threaded transmission, drives the support base 17 to move up and down along the screw's axial direction. The support height can be finely adjusted according to the ground's flatness, ensuring the compass remains level and providing a foundation for accurate measurements. For example, on uneven surfaces such as slopes, raising or lowering the support base 17 at different positions restores the compass to a horizontal position.
