Description

Technical Field

[0001] This invention relates to the field of geological compass equipment, specifically an adjustable optical aiming auxiliary device for a geological compass. Background Technology

[0002] Early compasses could only be aimed with the naked eye. Due to the limitations of human vision, they could only be used for close-range measurements. However, at close range, the compass needle could be severely affected by buildings and could not provide accurate readings. If long-distance measurements were required, direction could only be derived using a silk thread, which could not produce accurate data.

[0003] According to the compass instrument disclosed in the existing publication number CN201335694Y, it includes a compass body, a bracket, a rotating shaft, and a sight. The sight is connected to the compass body through the bracket, and the axis of the sight is located directly above the central axis of the compass body. The bracket is connected to the compass body through the rotating shaft, and the bracket includes: a sight fixing ring, an angle adjustment rotating shaft, a main bracket, and fastening screws. In use, this technical solution uses the sight for aiming, avoiding the influence of objects on the compass when measuring at close range, thus improving the accuracy of the measurement. Regarding the above technical solution, although it achieves long-distance aiming, it cannot achieve the limiting and fixing of the compass instrument after use, which is inconvenient in use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an adjustable optical aiming auxiliary device for a geological compass, thereby solving the problems mentioned in the background art. The present invention features a novel structure. In use, the movable plate moves via a fixed block, and the movable plate rotates the mounting plate. After the mounting plate rotates, an aiming mechanism is installed inside the mounting hole. The aiming mechanism and the marking arrow are perpendicularly distributed along a straight line with the same center, enabling long-distance measurement. When not in use, the mounting plate moves to the side of the fixed seat, and the limiting post cooperates with the mounting hole to achieve limiting and fixing between the movable seat and the fixed seat.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable optical aiming auxiliary device for a geological compass, comprising a fixed base, a movable base movably mounted on the top of the fixed base, the movable base being hinged to the fixed base via a fixed hinge, a fixed rod fixed to the top of the movable base, a movable block movably mounted between the fixed rods, a movable plate movably mounted at one end of the movable block, a fixed groove formed at one end of the movable plate, a fixed block rotatably mounted inside the fixed groove, a mounting plate welded to one end of the fixed block, a mounting hole formed on the mounting plate, and an aiming mechanism movably mounted inside the mounting hole. The aiming mechanism is an adjustable optical sight, specifically in the form of a telescope, enabling long-distance measurement.

[0006] Furthermore, a fixing bolt is rotatably installed on the side of the fixing block, and a support column is welded on the mounting plate. The support column is installed inside the fixing block through a bearing seat.

[0007] Furthermore, the support column has a fixing hole, one end of the fixing bolt is rotatably installed inside the fixing hole, and the fixing block is installed inside the fixing groove via a rotating shaft.

[0008] Furthermore, the fixed block has a threaded hole on its side, and a limit bolt is rotatably installed on the side of the movable plate, with one end of the limit bolt rotatably installed inside the threaded hole.

[0009] Furthermore, a sliding groove is formed on the inner wall of the fixed rod, and a slider moves inside the sliding groove, with one end of the slider fixed to the movable block.

[0010] Furthermore, the fixed base has a connecting cavity inside, and an indicator seat is fixedly installed inside the connecting cavity. A circular level and a marker arrow are fixedly installed inside the indicator seat.

[0011] Furthermore, the top of the movable seat has an observation window, and a marking line is fixed inside the observation window. A reflector is fixed on the inner wall of the movable seat, and a through hole is opened at the bottom of the fixed seat. A limit post is movably installed inside the through hole. Short-distance measurements can be performed through the marking line inside the observation window. The observation window and marking line are existing mature measurement technologies that can be directly used in this device.

[0012] Furthermore, the bottom of the fixed base has a cavity, one end of the limiting post is fixed with a ring seat, a tension mechanism is fixed between the ring seat and the inner wall of the cavity, the bottom of the limiting post has a groove, the tension mechanism is a tension spring, the tension spring always pushes the limiting post to be installed inside the mounting hole, and the limiting post realizes the limiting and fixing of the movable plate.

[0013] Furthermore, a fastening bolt is rotatably mounted on the bottom of the mounting plate, one end of which is movably mounted inside the groove, and a limit hole is opened on the side of the movable seat.

[0014] Furthermore, a connecting block is fixed on the movable block, and the connecting block is mounted on the movable plate via a rotating column.

[0015] The beneficial effects of this invention are:

[0016] 1. In use, the movable plate moves via the fixed block, and the movable plate rotates the mounting plate. After the mounting plate rotates, an aiming mechanism is installed inside the mounting hole. The aiming mechanism and the marking arrow are perpendicularly distributed along the same central line. Long-distance measurement is achieved through the aiming mechanism. When not in use, the mounting plate moves to the side of the fixed seat, and the limiting post cooperates with the mounting hole to achieve limiting and fixing between the movable seat and the fixed seat.

[0017] 2. In this invention, the aiming mechanism is installed inside the fixing hole and then fixed by compression bolts. Subsequently, the positioning post is installed inside the mounting hole, and one end of the fastening bolt is movably installed inside the groove at the bottom of the positioning post. The fastening bolt and the positioning post cooperate to fix the mounting plate and the positioning post, effectively avoiding the impact caused by the shaking of the movable seat.

[0018] 3. In this invention, after the fixed block rotates inside the fixed groove, the fixed block is limited by the matching of the limiting bolt and the threaded hole. When the mounting plate and the movable plate are distributed in the same straight line, the mounting hole forms an inner handle to facilitate the carrying and moving of the whole equipment. After the movable seat rotates on the fixed seat, it provides a vertical mounting point for the movable plate, which facilitates the quick adjustment and installation of the movable plate in the later stage.

[0028] See also Figures 1 to 7 This invention provides a technical solution: an adjustable optical aiming auxiliary device for a geological compass, comprising a fixed base 1, a movable base 2 movably mounted on the top of the fixed base 1, the movable base 2 being hinged to the fixed base 1 via a fixed hinge, a fixed rod 5 fixed on the top of the movable base 2, a movable block 6 movably mounted between the fixed rods 5, a movable plate 7 movably mounted on one end of the movable block 6, a fixed groove 9 formed at one end of the movable plate 7, a fixed block 8 rotatably mounted inside the fixed groove 9, a mounting plate 10 welded to one end of the fixed block 8, a mounting hole 12 formed on the mounting plate 10, and an aiming mechanism 34 movably mounted inside the mounting hole 12. The aiming mechanism 34 is an adjustable optical sight, specifically in the form of a telescope, enabling long-distance measurement.

[0029] In this embodiment, a fixing bolt 22 is rotatably installed on the side of the fixing block 8. A support column 27 is welded on the mounting plate 10. The support column 27 is installed inside the fixing block 8 through a bearing seat 29. A fixing hole 28 is opened on the support column 27. One end of the fixing bolt 22 is rotatably installed inside the fixing hole 28. The fixing block 8 is installed inside the fixing groove 9 through a rotating shaft 24. A threaded hole 25 is opened on the side of the fixing block 8. A limit bolt 26 is rotatably installed on the side of the movable plate 7. One end of the limit bolt 26 is rotatably installed inside the threaded hole 25. The limit bolt 26 is rotatably installed inside the threaded hole 25 to limit the fixing block 8. After the fixing block 8 is limited, the position of the mounting plate 10 is limited and fixed.

[0030] In this embodiment, a groove 17 is formed on the inner wall of the fixed rod 5, and a slider 18 is movable inside the groove 17. One end of the slider 18 is fixed to the movable block 6. A connecting cavity 13 is formed inside the fixed seat 1, and an indicator seat 14 is fixedly installed inside the connecting cavity 13. A circular level 16 and a marker arrow 15 are fixedly installed inside the indicator seat 14. An observation window 3 is formed on the top of the movable seat 2, and a marker line 4 is fixed inside the observation window 3. A reflector is fixed on the inner wall of the movable seat 2. A through hole is formed at the bottom of the fixed seat 1, and a limit post 11 is movably installed inside the through hole. Short-distance measurements can be performed through the marker line 4 inside the observation window 3. The observation window 3 and the marker line 4 are existing mature measurement technologies that can be directly used in this device.

[0031] In this embodiment, the bottom of the fixed base 1 has a cavity 30, one end of the limiting post 11 is fixed with a ring seat 33, a tension mechanism 32 is fixed between the ring seat 33 and the inner wall of the cavity 30, the bottom of the limiting post 11 has a groove 31, the bottom of the mounting plate 10 is rotatably mounted with a fastening bolt 23, one end of the fastening bolt 23 is movably mounted inside the groove 31, the side of the movable base 2 has a limiting hole 19, the movable block 6 is fixed with a connecting block 20, the connecting block 20 is mounted on the movable plate 7 through a rotating post 21, the tension mechanism 32 is a tension spring, the tension spring always pushes the limiting post 11 to be installed inside the mounting hole 12, and the limiting post 11 realizes the limiting and fixing of the movable plate 10.

[0032] Working principle: When measurement and observation are required, the ring seat 33 drives the limiting post 11 to displace and contract inside the cavity 30. When the limiting post 11 moves, the tension mechanism 32 deforms under tension, and the deformation generates a rebound force. This rebound force facilitates the return of the limiting post 11 to its original position. After the limiting post 11 moves, it moves out of the mounting hole 12. After the limiting post 11 moves out, the mounting plate 10 loses its limiting point. The mounting plate 10 rotates 90 degrees to the pivot shaft 24 and is aligned with the movable plate 7, thus aligning the movable plate 7 with the movable plate 7. The movable seat 2 rotates 90 degrees on the fixed seat 1 via a hinge. After rotating, the movable seat 2 is limited to 90 degrees. When the movable seat 2 is limited, the movable plate 7 drives the movable block 6 to slide inside the fixed rod 5. The movable block 6 moves horizontally inside the slide groove 17 via the slider 18. When the movable plate 7 moves to one end of the movable seat 2, it rotates 90 degrees. The movable plate 7 and the movable block 6 are distributed at 90 degrees. After the movable plate 7 rotates, one side of the movable seat 2 supports the movable plate 7. The mounting plate 10 is then rotated upwards again. Rotate 90 degrees, so that the mounting plate 10 and the movable plate 10 are distributed at 90 degrees. Rotate the mounting plate 10 through the support column 27. After the support column 27 is rotated 90 degrees through the bearing seat 28, it provides a position for the installation of the aiming mechanism 34. After the aiming mechanism 34 is installed inside the mounting hole 12, one end of the fastening bolt 23 realizes the compression limit of the aiming mechanism 34. The aiming mechanism 34 and the marking arrow 15 are distributed perpendicularly to the same center line. The aiming mechanism 34 realizes long-distance measurement. After the measurement is used, the mounting plate 10 is returned to its original state. After the movable seat 2 and the fixed seat 1 are closed, the ring seat 33 drives the limiting column 11 to displace and contract inside the cavity 30. After the mounting hole 12 moves to the side of the fixed seat 1, the tension mechanism 32 generates a rebound force to drive the limiting column 11 back to its original position. After the limiting column 11 moves to the inside of the mounting hole 12, the fastening bolt 23 rotates into the groove 31 at the bottom of the limiting column 11, so that the mounting plate 12 and the limiting column 11 are fixed.
