Description

Technical Field

[0001] This utility model relates to the field of astronomical technology, and more specifically, to an auxiliary star-finding structure for an astronomical telescope. Background Technology

[0002] Astronomical telescope star finding is usually accomplished through calibration and auxiliary tools: First, the star finding device (such as a red dot finder or a traditional optical finder) is calibrated to align with the center of the primary telescope's field of view; during observation, the approximate location of the target celestial body is quickly determined using the finder, and then fine-tuned to the center of the field of view using a low-power eyepiece. Finally, a high-power eyepiece or imaging device is switched for detailed observation. Modern telescopes can also be combined with motorized equatorial mounts, GPS positioning, or mobile star map apps to achieve automatic star finding and tracking, greatly improving efficiency, and are especially suitable for the precise capture of deep-sky objects or planets.

[0003] Existing methods for finding stars using astronomical telescopes can be divided into two categories: those using relatively easy-to-use optical methods such as red dot sights, and those using more difficult methods such as equatorial mounts for assistance. Considering portability, ease of use, and cost, the red dot sight structure is more suitable for beginners. However, in actual use, the optical method of finding stars involves changes such as target movement and equipment movement after capturing the position of a star. During a single search, the telescope's position and angle need to be frequently adjusted according to the star finding point, which is inconvenient for making small adjustments to the displacement during a single search, and has certain drawbacks. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing star-finding structures are limited by the way they are fixed to the telescope, requiring repeated adjustments to the star-finding position based on the telescope's location during star finding. To address the problems of existing technologies, this invention provides an auxiliary star-finding structure for astronomical telescopes.

[0005] The purpose and effect of this utility model are achieved by the following specific technical means: it includes a secondary tube, a mounting hoop is fixedly provided on one side of the secondary tube, and a red dot mirror tube and a mirror window are respectively provided through both ends of the secondary tube;

[0006] A red dot projector is fixed to the inner edge of one end of the red dot lens tube relative to the sub-tube, and a lens is snapped into the red dot lens tube. The focusing position of the red dot projector is located at the center point of the lens. The lens window extends along the inner side of the sub-tube toward the end of the red dot lens tube with a lens groove.

[0007] An external geared disk is movably disposed between the red dot lens barrel and the auxiliary barrel. An internal geared disk is rotatably engaged with the auxiliary barrel on the inner side of the external geared disk. A displacement sensor head and a damping head are respectively disposed at diagonal positions on the end edge of the red dot lens barrel. A rail seat is matched with the displacement sensor head and the damping head at the relative positions of the external geared disk. The displacement sensor head and the damping head are both rolled in engagement with the rail seat. The end of the connection between the internal geared disk and the auxiliary barrel is an angular displacement disk that is signal-connected to the displacement sensor head.

[0008] Furthermore: a wiring reel is fixed to the outside of the red dot lens tube, and a sensor tube is installed in the wiring reel, and the sensor tube is connected in series with the displacement sensor head and the angular displacement disk.

[0009] A further preferred embodiment: the tooth pattern specification of the outer toothed disc is larger than that of the inner toothed disc.

[0010] A further preferred embodiment: an adjusting roller is provided rollingly on the side edge of the outer toothed disc, and an adjusting wheel is provided extending from the end of the adjusting roller toward the side end of the auxiliary cylinder.

[0011] A further preferred embodiment: a frosted lens spot matching the focal point of the red dot projector is provided at the midpoint of the lens.

[0012] A further preferred embodiment: the damping head and the inner edge of the rail base are provided with a switch-type electromagnetic attraction structure, and the attraction end of the damping head and the rail base is the core position of the auxiliary cylinder and the red dot lens cylinder.

[0013] A further preferred embodiment: a through-hole tube is provided through the red dot lens barrel to the sub-tube end, and the through-hole tube covers the outside of the lens groove, and the through-hole tube is interference-fitted with the connecting end of the red dot lens barrel.

[0014] The beneficial effects of this utility model are:

[0015] This type of astronomical telescope's auxiliary star-finding structure, based on the traditional optical-assisted positioning principle, utilizes a red dot tube that can undergo radial and axial rotational displacement on the sub-tube. After the telescope is positioned, the red dot tube can be finely adjusted externally to align with the target star based on the center position of the red dot on the internal red dot transmitter. Displacement sensors within the red dot tube acquire the radial displacement and rotation angle of the red dot tube relative to the sub-tube, providing feedback data that allows the user to easily adjust the telescope. This eliminates the need to reposition the telescope to meet the star-finding requirements, facilitating single-use star finding and enhancing the structure's practicality.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the following description is provided in conjunction with the accompanying drawings. Figures 1-4 The present invention will be further described in detail below with specific embodiments. The following embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the scope of the present invention are within the patent protection scope of the present invention.

[0023] An auxiliary star-finding structure for an astronomical telescope includes a secondary tube 1, a mounting clamp 2 fixedly installed on one side of the secondary tube 1, and a red dot lens tube 3 and a lens window 4 respectively passing through both ends of the secondary tube 1.

[0024] A red dot lens tube 3 is fixed to the inner edge of one end of the red dot lens tube 1 relative to the secondary tube 1, and a lens 17 is snapped into the red dot lens tube 3. The focusing position of the red dot lens tube 15 is located at the center point of the lens 17. The lens window 4 extends along the inner side of the secondary tube 1 toward the end of the red dot lens tube 3 with a lens groove 14.

[0025] An outer geared disk 8 is movably arranged between the red dot lens barrel 3 and the auxiliary barrel 1. An inner geared disk 13 is rotatably engaged between the inner side of the outer geared disk 8 and the auxiliary barrel 1. A displacement sensor head 10 and a damping head 12 are respectively arranged at diagonal positions on the end edge of the red dot lens barrel 3. A rail seat 11 is matched with the outer geared disk 8 at the relative position of the displacement sensor head 10 and the damping head 12. The displacement sensor head 10 and the damping head 12 are both rolled in engagement with the rail seat 11. The end of the inner geared disk 13 connected to the auxiliary barrel 1 is an angular displacement disk that is signal-connected to the displacement sensor head 10.

[0026] This auxiliary star-finding structure is based on the red dot star-finding principle. The auxiliary tube 1 is aligned with the center of the field of view of the telescope's main mirror. When in use, the user observes the window position of the red dot tube 3 along the mirror window 4 and uses the position of the red dot emitted by the red dot emitter 15 in the red dot tube 3 to align with the target celestial body so that the telescope can quickly find the target.

[0027] Meanwhile, the structure further connects the auxiliary cylinder 1 and the red dot lens barrel 3 via a movable external gear plate 8. During use, the user can adjust the relative axial position of the red dot lens barrel 3 and the auxiliary cylinder 1 radially by holding the red dot lens barrel 3. That is, when holding the red dot lens barrel 3, external force is applied to the internal connecting end. Under this force, the red dot lens barrel 3 will adjust its relative radial coordinate position on the coaxial axis by the radial rolling of the displacement sensor head 10 on the rail base 11. Since the displacement sensor head 10 and the rail base 11 only move radially at a single angle, the user can simultaneously rotate the red dot lens barrel 3 by holding it to move the red dot lens barrel 3 and the external gear plate 8 along the internal gear... The disk 13 rotates relative to the secondary tube 1 to adjust the angular position of the displacement sensor head 10. This adjustment method can change the relative axial offset position of the red dot tube 3 and the secondary tube 1, that is, change the offset position of the red dot in the red dot tube 3 in the mirror window 4. The user can use the above adjustment method to align the position of the red dot with the celestial target. During the adjustment process, the displacement sensor head 10 records the rolling displacement in the track 11, and the angular displacement disk records the rotational angular displacement between the internal gear disk 13 and the secondary tube 1. The user can adjust the offset angle of the telescope's primary mirror as needed based on the feedback of specific displacement and angle data, providing auxiliary support for the telescope's star finding.

[0028] Compared to traditional red dot finder structures, this structure, while securing the telescope's primary mirror via mounting clamp 2, allows for secondary adjustments to the red dot tube 3 within the structure after initial positioning using the traditional red dot finder method. This adjustment controls the offset between the red dot and the viewport position of the secondary tube 1 (window 4). Consequently, after celestial object displacement or when observing adjacent objects, there's no need for secondary telescope adjustments using the finder structure. Multiple red dot displacements can be performed simply by adjusting the red dot tube 3, meeting the needs of celestial target tracking and adjacent target observation. This provides convenience for telescope finder work while satisfying the needs of beginners for portability, ease of use, and cost-effectiveness.

[0029] Among them, a wiring disk 5 is fixed on the outside of the red dot lens tube 3. A sensor tube 9 is set in the wiring disk 5. The sensor tube 9 is connected in series with the displacement sensor head 10 and the angular displacement disk. This structure mainly uses the external wiring disk 5 as the power distribution terminal of the displacement sensor head 10 and the angular displacement disk and the wireless transmission terminal for feedback displacement data. Its transmission method is determined according to the Internet of Things transmission method, Bluetooth transmission method or data cable connection method selected by the sensor tube 9.

[0030] Furthermore, the tooth pattern of the outer gear plate 8 is larger than that of the inner gear plate 13. Users can adjust the angle of the red dot lens tube 3 by holding and rotating the outer gear plate 8 or by holding and rotating the red dot lens tube 3 according to the needs of coarse and fine adjustment.

[0031] Based on the above, an adjusting roller 6 is rolled on the side edge of the outer gear disk 8, and an adjusting wheel 7 is extended from the end of the adjusting roller 6 toward the side end of the auxiliary cylinder 1. The user can rotate the adjusting wheel 7 to make the outer gear disk 8 roll through the transmission cooperation between the adjusting roller 6 and the outer gear disk 8, so as to facilitate the user to adjust the rotation angle of the red dot lens barrel 3.

[0032] Furthermore, a fuzzy lens spot matching the focal point of the red dot beam 15 is provided at the midpoint of the lens 17. The relatively shaped fuzzy lens spot forms a red dot mark with the infrared rays emitted by the red dot beam 15, which is displayed more intuitively in the lens groove 14, allowing the user to target the object based on the position of the red dot mark.

[0033] Furthermore, the inner edge of the damping head 12 and the rail base 11 is provided with a switch-type electromagnetic attraction structure, and the attraction end of the damping head 12 and the rail base 11 is the core position of the auxiliary cylinder 1 and the red dot lens cylinder 3. The user can open the electromagnetic end through the switch provided on the external wiring panel 5, and attract the damping head 12 through the electromagnetic switch energizing port to reset the position of the damping head 12, that is, reset the concentric position of the red dot lens cylinder 3 and the auxiliary cylinder 1. The damping head 12 is mainly used to provide damping and diagonal track support for the track displacement of the rail base 11 and the displacement sensing head 10, so as to ensure the displacement accuracy of the displacement sensing head 10 on the rail base 11 and the stability after hovering at each displacement position.

[0034] Furthermore, a through-hole tube section 16 is provided through the red dot lens barrel 3 to the end of the auxiliary barrel 1, and the through-hole tube section 16 covers the outside of the lens groove 14. The through-hole tube section 16 is interference-fitted with the connecting end of the red dot lens barrel 3. The lens groove 14 is covered by the through-hole tube section 16 structure, which further improves the light sealing between the auxiliary barrel 1 and the red dot lens barrel 3.

[0035] The star-finding structure uses a mounting clamp 2 to fix the auxiliary tube 1 to the outside of the telescope's main mirror. Based on the position of the main mirror, it ensures that the observation position of the auxiliary tube 1's window 4 is aligned with the center of the main mirror's field of view. In use, the user observes the window position of the red dot tube 3 along the window 4 and uses the position of the red dot emitted by the red dot emitter 15 in the red dot tube 3 to adjust the fixed position of the telescope so that the red dot is aligned with the target celestial body, allowing the telescope's main mirror observation window to quickly find the target.

[0036] Meanwhile, during use, the user can adjust the relative axial position of the red dot lens tube 3 and the auxiliary tube 1 radially by holding the red dot lens tube 3. That is, when holding the red dot lens tube 3, an external force is applied to the internal connecting end. After the force is applied, the red dot lens tube 3 will adjust its relative radial coordinate position on the coaxial position by the radial rolling of the displacement sensor head 10 on the rail seat 11. Since the displacement sensor head 10 and the rail seat 11 only move radially at a single angle, the user can simultaneously rotate the red dot lens tube 3 and the outer gear disk 8 relative to each other on the auxiliary tube 1 along the inner gear disk 13 by holding and rotating the red dot lens tube 3, thereby adjusting the angular position of the displacement sensor head 10. Alternatively, the user can adjust the position by turning the adjusting wheel 7 fixed on the side end of the auxiliary tube 1. In method 7, the outer gear disk 8 is rotated through the transmission cooperation between the adjusting roller 6 and the outer gear disk 8 to adjust the rotation angle of the red dot tube 3. This adjustment method can change the relative axial offset position of the red dot tube 3 and the auxiliary tube 1, that is, change the offset position of the red dot in the red dot tube 3 in the mirror window 4. The user can use the above adjustment method to align the position of the red dot with the celestial target. During the adjustment process, the displacement sensor head 10 records the rolling displacement in the track base 11, and the angular displacement disk records the rotation angle displacement between the inner gear disk 13 and the auxiliary tube 1. The user can adjust the offset angle of the telescope's main mirror adjustment structure as needed based on the specific displacement and angle data fed back by the sensor tube 9 in the wiring disk 5, providing auxiliary support for the telescope's star finding.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
