Description

TECHNICAL FIELD

[0001] The utility model relates to surveying and mapping instrument technical field more specifically, relate to a theodolite light supplementing structure. BACKGROUND

[0002] Theodolite is an optical instrument for measuring horizontal and vertical angles, widely used in topographic survey, engineering lofting and geodetic survey fields. When using theodolite, the main task is to find and accurately align the target point through the ocular lens, and to ensure that the point is correctly positioned through the crosshairs. The target point refers to a specific place or object whose position or angle, distance, etc. relative to other points you want to determine.

[0003] The objective lens of theodolite is mainly used for converging light rays to enable the target at a distance to be clearly imaged in the ocular lens, so that the observer can observe the details of the target at a distance through the ocular lens. The objective lens of theodolite is crucial for achieving accurate angle measurement, as it ensures that a sufficiently clear and accurate target image can be obtained even at a distance, facilitating accurate aiming and reading.

[0004] Currently, when using theodolite for observation, in the case of dark light weather or at night, the objective lens cannot obtain a sufficiently clear and accurate target image at this time, resulting in poor observation effect through the ocular lens for the observer, and inability to accurately aim and read. External lighting equipment is usually used for assistance, which is inconvenient to use and cannot well conform to the position of the objective lens imaging, affecting the observation effect.

[0005] Therefore, it is necessary to provide a theodolite light supplementing structure to solve the above technical problems. UTILITY MODEL CONTENTS

[0006] The utility model aims at providing a theodolite light supplementing structure to solve the above technical problems.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A theodolite light supplementing structure is installed on the objective lens of theodolite, comprising:

[0009] A sleeve is detachably installed on the objective lens, and the outer wall of the sleeve is provided with a plurality of support seats arranged in a ring array, and an installation groove is formed in the support seat;

[0010] A rotating shaft is rotatably arranged between the inner walls on both sides of the installation groove, and a connecting seat is arranged on the rotating shaft, and a light supplementing lamp is installed on the connecting seat through a support;

[0011] A limiting assembly is arranged in the installation groove and is used for limiting and fixing the position of the rotating shaft.

[0012] Furthermore, the limiting component includes:

[0013] A limiting ring is slidably disposed on the mounting groove, and there is at least one such limiting ring. The limiting ring is movably sleeved on the outside of the rotating shaft, and multiple toothed grooves are provided on one side of the limiting ring.

[0014] The sidewall of the connector is provided with a plurality of tooth-shaped protrusions that are adapted to the tooth groove.

[0015] Furthermore, the bottom wall of the mounting groove is provided with a sliding groove, and a connecting rod connected to the limiting ring is slidably connected in the sliding groove. An elastic element is provided between one end of the connecting rod and the side wall of the sliding groove.

[0016] Furthermore, the side wall of the support base is provided with a sliding groove that communicates with the sliding groove, and a push rod connected to the connecting rod is slidably connected in the sliding groove.

[0017] Furthermore, a screw is threadedly connected to the side wall of the support base, and a positioning block is rotatably connected to one end of the screw facing the limiting ring, while a rotating block is provided at the other end of the screw.

[0018] Furthermore, the outer wall of the objective lens is provided with an annular plate, the outer wall of the annular plate is provided with an external thread, and the inner wall of the sleeve is provided with an internal thread that matches the external thread.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This solution involves installing the supplementary lighting structure onto the objective lens of a theodolite. When used in low-light conditions or at night, the supplementary light can be turned on to illuminate the target point, enabling the objective lens to acquire a clear and accurate image of the target. This improves the observation effect through the eyepiece and effectively enhances the accuracy of aiming and reading. Furthermore, the supplementary light on the outer ring of the objective lens can effectively illuminate the target position as it is imaged by the objective lens, improving the observation effect. At the same time, no additional lighting equipment is required, reducing operational complexity, making it convenient to use, and highly practical.

[0021] The illumination angle of the supplementary light can be adjusted according to the specific illumination needs of the target point, making it suitable for different situations and highly flexible. This allows the observer to better observe the details of distant targets through the eyepiece. After being adjusted to the appropriate position, the connecting seat can be restricted by the limiting component to stabilize the supplementary light at the adjusted angle, resulting in good performance.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-7 A supplementary lighting structure for a theodolite, mounted on the objective lens 2 of the theodolite 1, includes:

[0033] The sleeve 3 is detachably mounted on the objective lens 2. The outer wall of the sleeve 3 is provided with multiple support seats 4 arranged in a ring array, and the support seats 4 are provided with mounting grooves 5.

[0034] A rotating shaft 6 is rotatably disposed between the inner walls of both sides of the mounting groove 5. A connecting seat 7 is provided on the rotating shaft 6, and a supplementary light 8 is mounted on the connecting seat 7 via a bracket.

[0035] The limiting component 9 is located in the mounting groove 5 and is used to limit and fix the rotation position of the rotating shaft 6.

[0036] In use, this supplementary lighting structure is installed onto the objective lens 2 of the theodolite 1, mainly by connecting the sleeve 3 to the objective lens 2. At this time, the outer ring of the objective lens 2 is equipped with a ring of supplementary lights 8. When used in low light conditions or at night, the supplementary lights 8 can be turned on to illuminate the target point, enabling the objective lens 2 to acquire a clear and accurate image of the target, thereby improving the observation effect through the eyepiece and effectively enhancing the accuracy of aiming and reading. Furthermore, the supplementary lights 8 on the outer ring of the objective lens 2 can effectively illuminate the target position as the objective lens images, improving the observation effect. Simultaneously, no additional lighting equipment is required, reducing operational complexity, making it convenient to use and highly practical.

[0037] The restriction on the rotation of the rotating shaft 6 can be released first by the limiting component 9. Then, the rotating shaft 6 and the connecting seat 7 can be rotated. The connecting seat 7 will then drive the supplementary light 8 to rotate, thereby changing the illumination angle of the supplementary light 8. It can be adjusted according to the specific illumination needs of the target point, and is suitable for different situations. It is highly flexible and has a wide range of applications, allowing the observer to better observe the details of distant targets through the eyepiece. After adjusting to the appropriate position, the connecting seat 7 can be restricted by the limiting component 9, so that the supplementary light 8 can be stabilized at the adjusted angle position, resulting in good performance.

[0038] For preferred options, please refer to [link / reference]. Figures 3-7 The limiting component 9 includes:

[0039] A limiting ring 91 is slidably disposed on the mounting groove 5 and there is at least one such limiting ring 91. The limiting ring 91 is movably sleeved on the outside of the rotating shaft 6. Multiple toothed grooves 92 are provided on one side of the limiting ring 91.

[0040] The side wall of the connector 7 is provided with a plurality of tooth-shaped protrusions 10 that are adapted to the tooth groove 92.

[0041] Specifically, when it is necessary to adjust the angle of the fill light 8, first move the limiting ring 91 horizontally so that the limiting ring 91 moves away from the connecting seat 7. When the toothed protrusion 10 of the connecting seat 7 disengages from the tooth groove 92 of the limiting ring 91, the connecting seat 7 and the rotating shaft 6 can rotate without restriction, thereby driving the fill light 8 to rotate, which can adjust the angle of the fill light 8. After adjusting the angle position, move the limiting ring 91 so that the toothed protrusion 10 is engaged in the tooth groove 92, thus realizing the rotation restriction of the connecting seat 7 and the rotating shaft 6, so that the fill light 8 is stable in this position.

[0042] For preferred options, please refer to [link / reference]. Figures 4-6The bottom wall of the mounting groove 5 is provided with a sliding groove 11. A connecting rod 12 connected to the limiting ring 91 is slidably connected in the sliding groove 11. An elastic element 13 is provided between one end of the connecting rod 12 and the side wall of the sliding groove 11. The elastic element 13 in this application can be a spring.

[0043] With this design, when the angle of the supplementary light 8 is adjusted, the moving limit ring 91 will drive the connecting rod 12 to move along the slide groove 11 and compress the elastic element 13. After the connecting seat 7 is adjusted, the limit ring 91 is released, and the rebound force of the elastic element 13 will drive the connecting rod 12 and the limit ring 91 to reset and move. That is, the limit ring 91 will drive the tooth groove 92 to lock the toothed protrusion 10 of the connecting seat 7, thus completing the position restriction of the connecting seat 7 after rotation.

[0044] For preferred options, please refer to [link / reference]. Figure 4 The side wall of the support base 4 is provided with a sliding groove 14 that communicates with the sliding groove 11, and a push rod 15 connected to the connecting rod 12 is slidably connected in the sliding groove 14.

[0045] This design allows the connecting rod 12 and the limiting ring 91 to be moved by pushing the push rod 15, making it easier and less strenuous to move the connecting rod 12 and the limiting ring 91, and improving its practicality.

[0046] For preferred options, please refer to [link / reference]. Figures 3-4 and Figures 6-7 The side wall of the support base 4 is threaded with a screw 16. One end of the screw 16 facing the limiting ring 91 is rotatably connected to a positioning block 17, and the other end of the screw 16 is provided with a rotating block 18.

[0047] This design, through the setting of the positioning block 17, can block the limiting ring 91. When the limiting ring 91 is moved so that the toothed groove 92 on it disengages from the toothed protrusion 10 of the connecting seat 7, the limiting ring 91 can no longer move after contacting the positioning block 17. At this time, it means that the limiting ring 91 has moved into place, that is, the toothed groove 92 has disengaged from the toothed protrusion 10. This can serve as a reminder to the operator, avoiding the situation where the operator moves too much and exerts too much effort, and also avoiding the situation where the toothed groove 92 and the toothed protrusion 10 are not completely disengaged due to insufficient movement distance. The effect is good.

[0048] Rotating the screw 16 can move the positioning block 17 horizontally, thereby adjusting the distance between the positioning block 17 and the limiting ring 91. This allows for flexible adjustment as needed.

[0049] For preferred options, please refer to [link / reference]. Figures 1-3An annular plate 19 is provided on the outer wall of the objective lens 2. The outer wall of the annular plate 19 has external threads, and the inner wall of the sleeve 3 has internal threads that match the external threads. When installing this supplementary lighting structure, the sleeve 3 is rotated in conjunction with the annular plate 19 of the objective lens 2. Through the action of the external threads of the annular plate 19 and the internal threads of the sleeve 3, the sleeve 3 can be connected to the annular plate 19.
