[0002] The function of the auxiliary aiming device of a total station is to adjust the position of the auxiliary aiming device of a total station for topographic surveying and mapping on the lens head of the total station through an alignment mechanism, so that the central axis of the auxiliary aiming device of the total station for topographic surveying and mapping corresponds to the central axis of the total station lens head. The auxiliary aiming device of the total station for topographic surveying and mapping is fixed to the lens head of the total station through a suction cup, so that the orientation of the small monocular telescope is the same as that of the total station lens head, thereby facilitating the staff to find the prism. An auxiliary aiming device with the existing publication number CN219495233U lacks a fine-tuning mechanism, making it difficult for the telescope to be parallel to the central axis of the total station lens head, thereby causing measurement errors. Therefore, an auxiliary aiming device is proposed. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides an auxiliary aiming device, which makes the telescope parallel to the central axis of the total station lens head. Since the amplitude of the lead screw movement is small and the inclination angle of the first slide groove is small, the telescope fine-tuning angle is small, making the fine-tuning more precise, so as to solve the problem of the lack of fine-tuning mechanism proposed in the above background technology, which makes it difficult for the telescope to be parallel to the central axis of the total station lens head, thereby causing measurement errors.

[0004] The two cams are connected to each other with a first end in contact with each other, and the second end in contact with each other is connected with a up-down knob to contact the two cams, and the two cams are connected with each other with a up-down knob to contact the two cams.

[0005] As a preferred technical solution of the present invention, the clamping mechanism includes a base to which the top surface of the mounting plate is fixed, and the top surface of the base is provided with an arc-shaped groove.

[0006] As a preferred technical solution of the present invention, a support is fixed to the top of one side of the base, and a fixing ring is rotatably connected to the inner side of the support.

[0007] As a preferred technical solution of the present invention, the fixing ring is in a semicircular structure, and the inner diameter of the fixing ring is the same as the inner diameter of the arc-shaped groove.

[0008] As a preferred technical solution of the present invention, a first strong magnet is fixed to one end of the fixing ring, a second strong magnet is magnetically matched to the outer side of the first strong magnet, and one end of the second strong magnet is fixedly connected to the outer side of the base.

[0009] As a preferred technical solution of the present invention, the slider is a circumferential structure, and one end of the slider passes through the interior of the second sliding groove and the first sliding groove and extends to the outside.

[0010] As a preferred technical solution of the present invention, the diameter of the sliding block is the same as the width of the second sliding groove and the first sliding groove.

[0011] The utility model provides an auxiliary aiming device, which has the following beneficial effects:

[0012] This auxiliary aiming device makes the telescope parallel to the central axis of the total station lens head. Since the movement amplitude of the lead screw is small and the inclination angle of the first slide groove is small, the fine-tuning angle of the telescope is small, thereby making the fine-tuning more precise and reducing the measurement error. Through the above process, the problem of the lack of fine-tuning mechanism, which makes it difficult for the telescope to be parallel to the central axis of the total station lens head and thus causes measurement errors, is solved.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] See also Figures 1 to 4The utility model provides a technical solution: an auxiliary aiming device, comprising a mounting plate 1, wherein the top surface of the mounting plate 1 is fixed with two clamping mechanisms 2, and the bottom surface of the mounting plate 1 is fixed with two side plates 3. The outer sides of the two side plates 3 are provided with a first slide groove 4, and the first slide groove 4 is an inclined structure. A rotating shaft 5 is fixed between the two mounting plates 1, and a mounting seat 6 is further provided between the two mounting plates 1. The interior of the mounting seat 6 is rotatably connected to the outer side of the rotating shaft 5. The second slide groove 7 is parallel to the mounting seat 6. The interior of the mounting seat 6 is provided with a mounting groove 8. The inner side of the mounting groove 8 is rotatably connected with a screw rod 9, which is parallel to the mounting seat 6. One end of the screw rod 9 passes through the interior of the mounting seat 6 and is fixed with a knob 10. A movable block 11 is fixed to the outer side of the screw rod 9. The width of the movable block 11 is the same as the width of the mounting groove 8. Slide blocks 12 are fixed on both sides of the movable block 11, and the outer sides of the slide blocks 12 are slidably connected to the second slide groove 7 and the inner side of the first slide groove 4 respectively;

[0023] The telescope is fixed by two clamping mechanisms 2, and then fine-tuning is performed. The screw rod 9 is driven to rotate by turning the knob 10, and the screw rod 9 drives the movable block 11 to move along the mounting groove 8. At the same time, the slider 12 on the movable block 11 moves along the inner sides of the second slide groove 7 and the first slide groove 4 respectively. Since the first slide groove 4 is an inclined structure, when the movable block 11 moves toward the height of the first slide groove 4, the side plate 3 gradually rotates downward along the rotation axis 5. When the movable block 11 moves toward the low angle of the first slide groove 4, the side plate 3 gradually rotates upward along the rotation axis 5, so that the telescope is parallel to the central axis of the total station lens head. Since the movement amplitude of the screw rod 9 is small and the inclination angle of the first slide groove 4 is small, the fine-tuning angle of the telescope is small, which makes the fine-tuning more accurate and reduces the measurement error. Through the above process, the problem of lack of fine-tuning mechanism, which makes it difficult for the telescope to be parallel to the central axis of the total station lens head, thereby causing measurement errors, is solved.

[0024] Furthermore, the clamping mechanism 2 includes a base 21 to which the top surface of the mounting plate is fixed, and an arc-shaped groove 22 is provided on the top surface of the base 21. A support 23 is fixed to the top of one side of the base 21, and a fixing ring 24 is rotatably connected to the inner side of the support 23. The fixing ring 24 has a semicircular structure, and the inner diameter of the fixing ring 24 is the same as the inner diameter of the arc-shaped groove 22. A first strong magnet 25 is fixed to one end of the fixing ring 24, and a second strong magnet 26 is magnetically matched to the outer side of the first strong magnet 25. One end of the second strong magnet 26 is fixedly connected to the outer side of the base 21. The slider 12 has a circumferential structure, and one end of the slider 12 extends to the outside through the second slide groove 7 and the first slide groove 4. The diameter of the slider 12 is the same as the width of the second slide groove 7 and the first slide groove 4.

[0025] When fixing the telescope, the telescope is placed in the arc groove 22 on the support 23, and then the fixing ring 24 is closed. The first strong magnet 25 on the fixing ring 24 and the second strong magnet 26 on the support 23 magnetically cooperate with each other, thereby completing the fixation between the fixing ring 24 and the support 23. The structural design is reasonable and compact, and it is convenient and quick to use.

[0026] The specific usage and function of this embodiment: The utility model fixes the telescope through two clamping mechanisms 2, and then performs fine-tuning. By turning the knob 10, the screw rod 9 is driven to rotate, and the screw rod 9 drives the movable block 11 to move along the mounting groove 8. At the same time, the slider 12 on the movable block 11 moves along the inner side of the second slide groove 7 and the first slide groove 4 respectively. Since the first slide groove 4 is an inclined structure, when the movable block 11 moves toward the height of the first slide groove 4, the side plate 3 gradually rotates downward along the rotating shaft 5. When the movable block 11 moves toward the low degree of the first slide groove 4, the side plate 3 gradually rotates upward along the rotating shaft 5, so that the telescope is parallel to the central axis of the total station lens head. Since the movement amplitude of the screw rod 9 is small and the inclination angle of the first slide groove 4 is small, the fine-tuning angle of the telescope is small, which makes the fine-tuning more accurate and reduces the measurement error.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
