[0032] Figure 1 is a structural schematic diagram of the equatorial mount adjustment device of this application. Figure 2 is a structural schematic diagram of the equatorial mount adjustment device of this application from another perspective. Figure 3 is a front view structural schematic diagram of the equatorial mount adjustment device of this application. Figure 4 is a side view structural schematic diagram of the equatorial mount adjustment device of this application.

[0033] Referring to Figures 1 to 4, this application provides an equatorial mount adjustment device, which is disposed between a support frame and a telescope. The equatorial mount adjustment device includes a connecting base 110 and an elevation adjustment assembly 200. The connecting base 110 is connected to the support frame. The elevation adjustment assembly 200 includes a first elevation mount 210, a second elevation mount 220, and a fine-tuning structure 230. The first elevation mount 210 is rotatably connected to the connecting base 110, and the rotation axis of the first elevation mount 210 is horizontally arranged to adjust the relative elevation angle between the first elevation mount 210 and the connecting base 110. The second elevation mount 220 is used to connect to the telescope, and the second elevation mount 220 is rotatably connected to the first elevation mount 210, and the rotation axis of the second elevation mount 220 is horizontally arranged. The two ends of the fine adjustment structure 230 are rotatably connected to the first elevation seat 210 and the second elevation seat 220, respectively. The two ends of the fine adjustment structure 230 can be relatively close or far apart so as to adjust the relative elevation angle between the second elevation seat 220 and the first elevation seat 210.

[0034] When a user needs to calibrate the telescope, they first adjust the relative elevation angle between the first elevation mount 210 and the connecting mount 110 to adjust the elevation angle between the telescope and the horizontal plane. Then, they adjust the relative angle between the second elevation mount 220 and the first elevation mount 210 to adjust the elevation angle between the telescope and the horizontal plane a second time. This facilitates quick and accurate angle adjustment of the telescope, simplifies the calibration operation of the astronomical telescope, and improves operational efficiency.

[0035] Figure 5 is a cross-sectional view of the structure shown in Figure 4. Figure 6 is an exploded view of the circumferential adjustment component of this application.

[0036] Referring to Figures 1 to 6, in this embodiment, the equatorial mount adjustment device includes a circumferential adjustment assembly 100. The circumferential adjustment assembly 100 includes a connecting seat 110 and a rotating seat 120. The connecting seat 110 is detachably connected to the support frame. The rotating seat 120 is rotatably connected to a first elevation seat 210, and the rotation axis of the rotating seat 120 extends in the vertical direction. The rotating seat 120 can connect to a first elevation seat 210 to drive the first elevation seat 210 to rotate circumferentially.

[0037] When users need to calibrate the telescope, they can quickly change the circumferential angle of the telescope by rotating the rotating base 120, thereby changing the orientation of the telescope and improving the adjustment efficiency of the telescope.

[0038] Referring to Figures 1 to 6, in this embodiment, the connecting seat 110 has a threaded hole 111, which extends in the vertical direction so that the connecting seat 110 is threadedly connected to the support frame, thereby effectively improving the assembly and disassembly efficiency of the astronomical telescope.

[0039] Referring to Figures 1 to 6, in this embodiment, the upper surface of the connecting seat 110 is provided with a limiting shaft protrusion 112, which can be detachably extended into the rotating seat 120 so that the rotating seat 120 can rotate around the axis of the limiting shaft protrusion 112.

[0040] In some embodiments, the limiting shaft protrusion 112 passes through the rotating seat 120 so that the rotating seat 120 is sleeved on the limiting shaft protrusion 112, thereby ensuring the connection strength between the rotating seat 120 and the limiting shaft protrusion 112.

[0041] Referring to Figures 1 to 6, in this embodiment, the connecting seat 110 is provided with an adjusting block 113 protruding relative to the rotating seat 120. The adjusting block 113 is capable of rotating relative to the rotating seat 120 about the rotation axis of the rotating seat 120. The rotating seat 120 is provided with a plurality of circumferential limiting members 310 relative to the adjusting block 113. The plurality of circumferential limiting members 310 are capable of moving toward the adjusting block 113 to press against the adjusting block 113 and limit the relative rotation of the connecting seat 110 and the rotating seat 120.

[0042] When the user adjusts the circumferential angle of the telescope, the rotating base 120 and the connecting base 110 rotate relative to each other. After the rotating base 120 drives the elevation adjustment component 200 to rotate, it adjusts multiple circumferential limiting members 310 so that the multiple circumferential limiting members 310 move toward the adjusting block 113. The circumferential limiting members 310 resist and limit the rotation of the adjusting block 113, thereby preventing the elevation adjustment component 200 from rotating unexpectedly under the action of gravity or external force, and ensuring the reliability and stability of the astronomical telescope.

[0043] In some embodiments, the rotating seat 120 is provided with two directional limiting members 310 relative to the adjusting block 113. The two directional limiting members 310 are respectively provided relative to the two ends of the adjusting block 113 so as to abut and limit the two ends of the adjusting block 113 respectively, thereby stably and reliably limiting the relative rotation angle between the connecting seat 110 and the rotating seat 120.

[0044] In other embodiments, the adjusting block 113 extends in an arc shape. Two circumferential limiting members 310 are disposed on both sides of the adjusting block 113 and can move along the interval direction between the two ends of the adjusting block 113 to ensure that the circumferential limiting members 310 can stably and reliably limit the adjusting block 113.

[0045] In some embodiments, the circumferential limiting member 310 may be an adjusting bolt. The circumferential limiting member 310 is threadedly connected to the rotating seat 120 to facilitate adjustment of the relative position of the circumferential limiting member 310 and the rotating seat 120.

[0046] In other embodiments, the circumferential relative rotation angle between the rotating seat 120 and the connecting seat 110 is 5°.

[0047] Figure 7 is a structural schematic diagram of the elevation angle adjustment assembly of this application. Figure 8 is a structural schematic diagram of the structure shown in Figure 7 after removing the first locking structure.

[0048] Referring to Figures 1 to 8, in this embodiment, the rotating base 120 includes a base plate 121 and two oppositely disposed fixing ears 123. The base plate 121 extends horizontally. The base plate 121 is rotatably sleeved on the limiting shaft protrusion 112. The two fixing ears 123 are spaced apart on the base plate 121, and both fixing ears 123 extend in the vertical direction. The opposite sides of the first elevation angle base 210 are rotatably disposed on the two fixing ears 123 so as to adjust the relative elevation angle between the first elevation angle base 210 and the base plate 121.

[0049] In some embodiments, the lower surface of the substrate 121 is recessed with a receiving groove 122 relative to the adjusting block 113. The receiving groove 122 can accommodate the adjusting block 113 and allow the adjusting block 113 to rotate. Circumferential limiting members 310 are respectively disposed on opposite side walls of the receiving groove 122, so that the ends of the circumferential limiting members 310 can extend or retract within the receiving groove 122, thereby resisting the relative rotation between the adjusting block 113 and the substrate 121. Furthermore, interference from external structures on the adjusting block 113 and the circumferential limiting members 310 can be avoided, improving the stability and reliability of the circumferential adjustment assembly 100.

[0050] Referring to Figures 1 to 6, in this embodiment, a guide hole 1231 may be provided on the fixing ear 123. The guide hole 1231 extends in an arc shape around the rotation axis between the fixing ear 123 and the first elevation seat 210, and a portion of the first elevation seat 210 can pass through the guide hole 1231, so that the user can apply external force to the first elevation seat 210 to lock the first elevation seat 210.

[0051] Referring to Figures 1 to 6, in this embodiment, the circumferential adjustment assembly 100 may further include a cover plate 130. The cover plate 130 is located on the side of the rotating seat 120 opposite to the connecting seat 110. The limiting shaft protrusion 112 passes through the rotating seat 120 to be detachably connected to the cover plate 130, thereby confining the base plate 121 between the connecting seat 110 and the cover plate 130, effectively ensuring the stability, reliability and safety of the circumferential adjustment assembly 100.

[0052] In some embodiments, a first rotary bearing 321 may be provided between the connecting seat 110 and the base plate 121 to effectively reduce the rotational friction between the connecting seat 110 and the rotating seat 120. A second rotary bearing 322 may be provided between the rotating seat 120 and the cover plate 130 to reduce the rotational friction between the rotating seat 120 and the cover plate 130.

[0053] In other embodiments, the first rotary bearing 321 and the second rotary bearing 322 may be thrust ball bearings.

[0054] In some embodiments, a third rotary bearing is provided between the substrate 121 and the limiting shaft protrusion 112 to reduce the friction between the limiting shaft protrusion 112 and the substrate 121. In other embodiments, the third rotary bearing may be a rolling bearing.

[0055] Referring to Figures 1 to 8, in this embodiment, the elevation adjustment assembly 200 is located between the two fixed lugs 123. The elevation adjustment assembly 200 includes a first elevation mount 210 and a second elevation mount 220. The first elevation mount 210 is rotatably connected to the two fixed lugs 123, and its rotation axis extends horizontally to adjust the relative elevation angle between the first elevation mount 210 and the base plate 121. The second elevation mount 220 is rotatably connected to the first elevation mount 210, and its rotation axis extends horizontally to adjust the relative elevation angle between the second elevation mount 220 and the first elevation mount 210. The first and second elevation mounts cooperate to facilitate precise and efficient calibration of the telescope's angle by the user.

[0056] Referring to Figures 1 to 8, in this embodiment, the first elevation angle seat 210 includes a first seat body 211 and two rotating ears 212. The first seat body 211 extends horizontally. The two rotating ears 212 are disposed opposite to each other on the first seat body 211, and the two rotating ears 212 are rotatably connected to two fixed ears 123, thereby realizing the relative rotation between the first elevation angle seat 210 and the rotating seat 120.

[0057] In some embodiments, a first limiting protrusion 214 protrudes from one end of the first base 211 away from its own axis of rotation. The first limiting protrusion 214 is rotatably connected to the fine-tuning structure 230 to realize relative rotation between the fine-tuning structure 230 and the first base 211.

[0058] In some embodiments, there are two first limiting protrusions 214, which clamp the lower end of the fine-tuning structure 230. In some embodiments, a first limiting pivot 215 is detachably provided on the first limiting protrusion 214, extending out of the first limiting protrusion 214 and rotatably connected to the lower end of the fine-tuning structure 230. In some embodiments, there are two first limiting pivots 215, which are coaxially arranged.

[0059] Referring to Figures 1 to 8, in this embodiment, a guide post 213 protrudes from the first base 211 relative to the guide hole 1231. The guide post 213 is slidably disposed within the guide hole 1231. When the first base 211 rotates relative to the base plate 121, the guide post 213 can slide within the guide hole 1231, thereby improving the structural stability and reliability of the equatorial mount adjustment device.

[0060] In some embodiments, the relative elevation angle between the first elevation seat 210 and the rotating seat 120 varies from 0° to 60°. That is, the relative elevation angle between the first elevation seat 210 and the connecting seat 110 varies from 0° to 60°.

[0061] Referring to Figures 1 to 8, in this embodiment, the elevation angle adjustment assembly 200 further includes a first locking structure 330. The first locking structure 330 is disposed on the fixed lug 123 and / or the first elevation angle seat 210 to lock the relative elevation angle between the first elevation angle seat 210 and the rotating seat 120.

[0062] In some embodiments, the first locking structure 330 can be a nut. The nut is threaded onto the guide post 213 and located at the end of the guide post 213 away from the center of the first base 211. When the nut rotates about the guide post 213 to move toward the fixing lug 123, the nut can press against the fixing lug 123, thereby locking the relative elevation angle between the first base 211 and the base plate 121 through the friction and pressure between the nut and the fixing lug 123, thus improving the stability and reliability of the equatorial mount adjustment device.

[0063] In other embodiments, the first locking structure 330 may be a locking post. The locking post is detachably inserted into the fixing ear 123 and the rotating ear 212 to limit the relative elevation angle between the first seat 211 and the base plate 121. In other embodiments, the locking post is detachably inserted into the fixing ear 123 and the guide post 213 to limit the relative elevation angle between the first seat 211 and the base plate 121.

[0064] Referring to Figures 1 to 8, in this embodiment, the elevation angle adjustment assembly 200 further includes a second elevation angle seat 220. The second elevation angle seat 220 has a second limiting protrusion 221 protruding from the fine-tuning structure 230. The second limiting protrusion 221 is rotatably connected to the fine-tuning structure 230 to realize the relative rotation between the fine-tuning structure 230 and the second elevation angle seat 220.

[0065] In some embodiments, a second limiting shaft 222 is detachably provided on the second limiting protrusion 221. The second limiting shaft 222 is used to rotatably connect with the upper end of the fine-tuning structure 230 and limit the fine-tuning structure 230.

[0066] In some embodiments, the relative elevation angle between the second elevation mount 220 and the first elevation mount 210 varies within a range of 5°, thereby enabling precise adjustment of the telescope through the fine-tuning structure 230, allowing the telescope to be calibrated quickly.

[0067] In this embodiment, the second elevation mount 220 can be an equatorial mount, allowing the equatorial mount adjustment device to directly adjust the telescope's elevation angle. Furthermore, this simplifies the structure of the equatorial mount adjustment device and the equatorial mount itself, resulting in a smaller and more stable astronomical telescope, effectively improving the assembly, disassembly, and usage efficiency of the telescope.

[0068] In some embodiments, an equatorial mount is provided on the telescope. A second elevation mount 220 can be connected to the equatorial mount to adjust the elevation angle of the equatorial mount via an equatorial mount adjustment device, thereby adjusting the elevation angle of the telescope.

[0069] Referring to Figures 1 to 8, in this embodiment, the elevation angle adjustment assembly 200 further includes an adjustment shaft 340, which passes through the first elevation angle seat 210, the second elevation angle seat 220, and the two fixed ears 123, so that the rotation axis of the first elevation angle seat 210 coincides with the rotation axis of the second elevation angle seat 220, thereby ensuring the structural stability of the equatorial mount adjustment device and facilitating the calculation of the relative elevation angle between any two of the rotating seat 120, the first elevation angle seat 210, and the second elevation angle seat 220.

[0070] In some embodiments, the adjusting shaft 340 extends horizontally to sequentially pass through the fixed ear 123, the rotating ear 212 and the second elevation seat 220, thereby facilitating the calculation of the relative elevation angle between the second elevation seat 220 and the substrate 121.

[0071] In some embodiments, the adjusting shaft 340 can be engaged with the first elevation seat 210 so that the adjusting shaft 340 can rotate synchronously with the first elevation seat 210 about the rotation axis of the adjusting shaft 340.

[0072] In other embodiments, the adjusting shaft 340 can be a two-end shaft structure. The two end shafts are respectively disposed on both sides of the second elevation seat 220, and the two end shafts are coaxially disposed so as to pass through the second elevation seat 220, the rotating lug 212 and the fixed lug 123 respectively.

[0073] Referring to Figures 1 to 8, in this embodiment, one end of the adjusting bearing extends through the fixing lug 123. The elevation adjustment assembly 200 also includes a second locking structure 350. The second locking structure 350 is located on the outside of the fixing plate and is connected to the adjusting bearing to limit the rotation of the adjusting bearing, thereby enabling the second locking structure 350 and the adjusting shaft 340 to further lock the relative elevation angle between the second elevation seat 220 and the base plate 121, improving the reliability and stability of the equatorial mount adjustment device.

[0074] In some embodiments, the second locking structure 350 can be a nut that is threadedly connected to the adjusting shaft 340. The nut can rotate on the adjusting bolt and can be pressed against the fixing ear 123, thereby locking the adjusting shaft 340 by the pressure and friction between the nut and the fixing ear 123 and preventing the adjusting shaft 340 from rotating.

[0075] In other embodiments, the second locking structure 350 may be a locking post, which may be detachably inserted into the adjusting shaft 340 and the fixing ear 123 to limit the relative rotation between the adjusting shaft 340 and the fixing ear 123.

[0076] Referring to Figures 1 to 8, in this embodiment, the fine-tuning structure 230 is disposed between the first elevation seat 210 and the second elevation seat 220. The two ends of the fine-tuning structure 230 can move away from or close to each other, so that the second elevation seat 220 can rotate relative to the first elevation seat 210 about the rotation axis of the adjustment shaft 340, thereby adjusting the relative elevation angle between the second elevation seat 220 and the first elevation seat 210.

[0077] The fine-tuning structure 230 includes a rotating block 231, an adjusting wheel 232, and an adjusting rod 233. The rotating block 231 is rotatably mounted on the first elevation angle seat 210, and the adjusting wheel 232 is rotatably mounted on the rotating block 231. The rotation axis of the adjusting wheel 232 is perpendicular to the rotation axis of the rotating block 231. The adjusting rod 233 is movably mounted on the rotating block 231. One end of the adjusting rod 233 is connected to the adjusting wheel 232, and the other end of the adjusting rod 233 is rotatably connected to the second elevation angle seat 220.

[0078] The user can adjust the distance between the rotating block 231 and the connection point between the adjusting rod 233 and the second elevation seat 220 by rotating the adjusting wheel 232 to drive the adjusting rod 233 to move relative to the rotating block 231.

[0079] Referring to Figures 1 to 8, in this embodiment, the rotating block 231 is rotatably connected to the first limiting protrusion 214, and the rotation axis of the rotating block 231 extends horizontally. The rotation axis at the connection between the fine-tuning structure 230 and the first elevation seat 210 is parallel to the rotation axis of the second elevation seat 220. That is, the rotation axis of the rotating block 231 is parallel to the rotation axis of the adjusting shaft 340.

[0080] The two opposite ends of the rotating block 231 can be connected to two first limiting protrusions 214, so that the two first limiting protrusions 214 clamp the rotating block 231, thereby improving the connection stability and reliability between the fine adjustment structure 230 and the first elevation seat 210.

[0081] In other embodiments, the two first limiting shafts 215 are rotatably connected to the two ends of the rotating block 231, so that the rotating block 231 can rotate around the first limiting shafts 215.

[0082] Referring to Figures 1 to 8, in this embodiment, a rotating groove 2311 is provided in the rotating block 231, and part of the adjusting wheel 232 is accommodated in the rotating groove 2311. One end of the adjusting rod 233 passes through the rotating block 231 and the adjusting wheel 232 along the rotation axis of the adjusting wheel 232, and is threadedly connected to the adjusting wheel 232, thereby effectively improving the stability and reliability of the fine-tuning structure 230.

[0083] Referring to Figures 1 to 8, in this embodiment, the adjusting wheel 232 and the adjusting rod 233 are worm gear structures, thereby enabling fine-tuning of the relative elevation angle between the second elevation seat 220 and the first elevation seat 210, improving the adjustment precision and stability of the equatorial mount adjustment device. The lower end of the adjusting rod 233 passes through the rotating block 231 and is threadedly connected to the adjusting wheel 232, so that the lower end of the adjusting rod 233 can rotate around the first limiting shaft 215 following the rotating block 231. The upper end of the adjusting rod 233 is rotatably connected to the second limiting protrusion 221 to prevent the second elevation seat 220 from interfering with the movement and rotation of the adjusting rod 233, improving the reliability and stability of the fine-tuning mechanism.

[0084] In some embodiments, the rotation axis at the connection between the fine-tuning structure 230 and the second elevation seat 220 is parallel to the rotation axis of the second elevation seat 220. That is, the rotation axis of the adjusting rod 233 and the second limiting protrusion 221 is parallel to the rotation axis of the adjusting shaft 340.

[0085] In some embodiments, the upper end of the adjusting rod 233 is rotatably connected to the second limiting shaft 222 so that the adjusting rod 233 can rotate around the second limiting shaft 222, thereby facilitating the disassembly and maintenance of the fine-tuning structure 230 while ensuring the structural strength and stability of the elevation adjustment assembly 200.

[0086] In some embodiments, the fine-tuning structure 230 can rotate a block 231, an adjusting rod 233, and a driver (not shown). The rotating block 231 is rotatably mounted on a first limiting protrusion 214. One end of the adjusting rod 233 is movably connected to the rotating block 231 along its own axial direction, and the other end of the adjusting rod 233 is rotatably connected to a second limiting protrusion 221. The driver is mounted on the rotating block 231 and connected to the adjusting rod 233, thereby enabling the adjusting rod 233 to move relative to the rotating block 231.

[0087] In other embodiments, the actuator can be a hydraulic cylinder, and the adjusting rod 233 can be a telescopic rod. Alternatively, the actuator can be a drive motor, and the adjusting rod 233 can be provided with a rack that meshes with the drive motor.

[0088] Referring to Figures 1 to 8, this application provides an equatorial mount adjustment device. When a user assembles an astronomical telescope, the connecting seat 110 is connected to the support frame and the telescope respectively to facilitate the calibration of the telescope's circumferential angle and elevation angle.

[0089] When calibrating the telescope, the user first rotates the circumferential limiting member 310 to move it away from the adjusting block 113. Then, the rotating base 120 is rotated to drive the elevation adjustment component 200 on the rotating base 120 to rotate, thereby adjusting the circumferential angle of the telescope. After the circumferential angle adjustment is completed, the circumferential limiting member 310 is rotated so that it abuts against the adjusting block 113, thereby limiting the circumferential angle between the rotating base 120 and the connecting base 110.

[0090] After the circumferential angle of the astronomical telescope is calibrated, the first locking structure 330 is adjusted first, and then an external force is applied to the first elevation seat 210 to make the first elevation seat 210 rotate around the adjusting shaft 340. The guide post 213 slides in the guide hole 1231, thereby adjusting the relative elevation angle between the first elevation seat 210 and the rotating seat 120. After the relative elevation angle between the first elevation seat 210 and the rotating seat 120 is adjusted, the first locking structure 330 is rotated to limit the relative position of the first elevation seat 210 and the fixed ear 123, thereby locking the relative elevation angle between the first elevation seat 210 and the rotating seat 120.

[0091] After the first elevation mount 210 is adjusted, the user can rotate the adjustment wheel 232 to drive the adjustment rod 233 to move relative to the rotating block 231. The rotating block 231 rotates around the first limiting shaft 215, and the upper end of the adjustment rod 233 rotates around the second limiting shaft 222, causing the upper end of the adjustment rod 233 to move away from or closer to the rotating block 231, thereby adjusting the relative elevation angle between the second elevation mount 220 and the first elevation mount 210. After the relative elevation angle of the second elevation mount 220 is adjusted, the second locking structure 350 is rotated to lock the adjustment shaft 340, thereby further limiting the relative elevation angle between the base plate 121 and the second elevation mount 220. This facilitates quick and accurate angle adjustment of the telescope, simplifies the calibration operation of the astronomical telescope, and improves operating efficiency.

[0092] This application also provides an astronomical telescope, comprising: a support frame, an equatorial mount adjustment device as described above, and a telescope. The support frame is capable of being supported on a working surface. The equatorial mount adjustment device is detachably mounted on the support frame. The telescope is detachably connected to the equatorial mount.

[0093] When a user assembles an astronomical telescope and calibrates it, the relative elevation angle between the connector 110, the first elevation mount 210, and the second elevation mount 220 can be adjusted quickly and accurately, simplifying the calibration operation of the astronomical telescope and improving the operating efficiency.

[0094] In this embodiment, the astronomical telescope also includes an equatorial mount. The equatorial mount is detachably connected to the second elevation mount 220 of the equatorial mount adjustment device, so that the equatorial mount adjustment device is detachably connected to the telescope via the equatorial mount. The equatorial mount adjustment device is used to adjust the circumferential and elevation angles of the equatorial mount, thereby calibrating the telescope and facilitating the equatorial mount to drive the telescope to track celestial motion at a constant speed.

[0095] In some embodiments, the second elevation mount 220 in the equatorial mount adjustment device is the equatorial mount itself, allowing the user to directly adjust the circumferential angle of the equatorial mount via the circumferential adjustment component 100, and directly adjust the pitch angle of the equatorial mount via the first elevation mount 210, the first locking structure 330, and the fine-tuning structure 230, thereby achieving efficient and rapid adjustment of the equatorial mount and the telescope. Furthermore, the integrated design of the equatorial mount adjustment device and the equatorial mount effectively reduces the assembly steps of the astronomical telescope, improves assembly efficiency, and enhances the user experience.

[0096] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
