Description

Technical Field

[0001] This utility model relates to an equatorial mount, and more particularly to a heavy-duty harmonic equatorial mount. Background Technology

[0002] The harmonic equatorial mount is an advanced astronomical telescope mount that uses harmonic drive technology to achieve high-precision tracking and positioning. This type of equatorial mount is particularly suitable for deep-sky photography and other applications that require long exposures.

[0003] Currently available harmonic equatorial mounts are mostly one-piece designs, meaning the latitude adjustment device and the mount itself are fixedly connected and cannot be disassembled. This makes them prone to colliding with the mount's tripod when setting up large or long telescopes, potentially damaging the equipment. Furthermore, cables connected to the mount are easily tangled, damaging the mount. Therefore, there is a need to design a heavy-duty harmonic equatorial mount that is easy to disassemble and has cable management capabilities. Utility Model Content

[0006] The latitude adjustment device includes a connecting base, support blocks, RA support base, RA fixing base, equatorial mount body and locking screws. Two support blocks are connected to the top of the connecting base along its length. The RA support base is rotatably connected between the two support blocks. The RA fixing base is fixedly connected to the top of the RA support base. Multiple sets of locking screws are threaded onto the RA fixing base. The equatorial mount body is connected to the RA fixing base through the locking screws.

[0007] The main body of the equatorial mount consists of a harmonic reducer, a stepper motor, a synchronous pulley, a synchronous belt, an optical couple, a control panel, and a guide rail locking assembly. The connection between the guide rail locking assembly and the equatorial mount body adopts a clutch structure, which facilitates balance adjustment during the installation of the telescope tube.

[0008] Optionally, two adjusting plates are fixedly connected to the RA support base, and a latitude adjusting positioning block is slidably connected to the top of the connecting base. The latitude adjusting positioning block passes through the two adjusting plates, and a latitude adjusting screw is rotatably connected to the connecting base.

The T-shaped through hole inside the equatorial mount body is connected to the longitudinal through hole of the RA support base. The support base is provided with a longitudinal through hole, which is the same as the through hole of the equatorial mount body. A protective tube is provided at the T-shaped through hole inside the equatorial mount body and at the longitudinal through hole of the RA support base.

[0013] Optionally, the upper part of the support block with the chamber is provided with an installation groove, which communicates with the chamber, and a level and a lighting lamp are installed in the installation groove.

[0014] Optionally, the connection between the guide rail locking assembly and the equatorial mount body 10 adopts a clutch structure to facilitate balance adjustment during the installation of the telescope tube.

[0015] Optionally, the guide rail locking assembly includes a connecting cylinder 20, which is bolted to the harmonic reducer 26. The EDC shaft 23 is bolted to the guide rail plate 21, and the guide rail plate 21 is fixed to the connecting cylinder 20 with bolts and positioned with locating pins.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example: A heavy-duty harmonic equatorial mount, such as Figures 1-3As shown, the device consists of two parts: a latitude adjustment device and an equatorial mount. The two are connected by locking screws. The latitude adjustment device includes a connecting base 1, support blocks 6, an RA support seat 8, an RA fixing seat 9, the equatorial mount body 10, and locking screws 12. Two support blocks 6 are connected to the top of the connecting base 1 along its length. The RA support seat 8 is rotatably connected between the two support blocks 6. The RA fixing seat 9 is fixedly connected to the top of the RA support seat 8, and multiple sets of locking screws 12 are threaded onto the RA fixing seat 9. The equatorial mount body 10 is connected to the RA fixing seat 9 via the locking screws 12. Here, the equatorial mount body 10 can be disassembled using the locking screws 12. When not in use, the device is divided into two parts, which facilitates carrying and storing the device. When in use, the device can be quickly assembled using the locking screws 12, thus improving the flexibility of the device. After disassembly, the equatorial mount body 10 can also be mounted on other fixed supports for independent use, enabling omnidirectional observation without blind spots.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, two adjusting plates 7 are fixedly connected to the RA support base 8. A latitude adjusting positioning block 41 is slidably connected to the top of the connecting base 1, passing through the two adjusting plates 7. A latitude adjusting screw 4 is rotatably connected to the connecting base 1, passing through the latitude adjusting positioning block 41. The latitude adjusting positioning block 41 and the latitude adjusting screw 4 are threadedly connected. Latitude fixing screws 5 are threadedly connected to both support blocks 6, and the latitude fixing screws 5 are used to limit the adjusting plates 7. A fixed base 3 is rotatably connected to the bottom of the connecting base 1. An azimuth adjusting screw 2 is threadedly connected to the side wall of the fixed base 3, and the azimuth adjusting screw 2 is used to limit the connecting base 1. Here, the locking screw 12 is used to secure the base 1. The equatorial mount body 10 is fixed on the RA mounting base 9. Then, the latitude adjustment screw 4 is rotated counterclockwise, causing the latitude adjustment positioning block 41 to slide outward. Since the latitude adjustment positioning block 41 passes through the adjustment plate 7, the latitude adjustment positioning block 41 drives the adjustment plate 7 to rotate upward when it slides outward, thereby driving the RA support base 8, which is fixed to the adjustment plate 7, to rotate upward, thus adjusting the pitch angle of the device. After the device is adjusted to the predetermined angle, the latitude fixing screws 5 on both sides of the device are rotated clockwise, causing the latitude fixing screws 5 to rotate inward. The latitude fixing screws 5 then press the adjustment plate 7, thereby fixing the adjustment plate 7 and the RA support base 8.

[0031] like Figure 2 and Figure 5As shown, the equatorial mount body 10 has horizontal and vertical through holes, which are interconnected to form a T-shaped through hole. The T-shaped through hole inside the equatorial mount body 10 is connected to the vertical through hole of the RA support base 8. The support base has a vertical through hole, which is the same as the through hole of the equatorial mount body 10. A cable protection tube 11 is provided at the T-shaped through hole inside the equatorial mount body 10 and at the vertical through hole of the RA support base 8. The design of the T-shaped through hole and the vertical through hole can prevent the connecting cables of the device from being exposed messily outside the device, and can organize and limit the connecting cables. At the same time, the cable protection tube 11 is also provided to prevent the cables from rubbing against the internal parts of the equatorial mount body 10, thus protecting the stable operation of the device.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, one of the support blocks 6 has a chamber containing a latitude scale 15. The latitude scale 15 is connected to the RA support base 8 and rotates with it. The support block 6 has an observation hole to check the adjustment of the latitude scale 15. A pointer is located on the side of the support block 6 near the observation hole. A mounting groove is located on the upper part of the support block 6 containing the chamber, communicating with the chamber. A level 13 and a lighting lamp 14 are installed in the mounting groove. Here, the latitude scale 15 is located on the RA support base... 8. When rotating, the latitude scale 15 is marked with latitude values. When the latitude scale 15 rotates, the latitude indicated by the pointer on the support block 6 changes. Thus, the user can understand the latitude change information by observing the observation hole. The level 13 helps the user set the device in a horizontal position through the bubble and scale lines in the closed tube. When the device is in an environment with poor lighting conditions, the lighting lamp 14 can be turned on to increase the brightness in the cavity of the support block 6, thereby facilitating the observation of the latitude scale 15 and the level 13.

[0033] like Figure 8 As shown, the connection between the guide rail locking assembly and the equatorial mount body 10 adopts a clutch structure, which facilitates balance adjustment during mirror tube installation. The guide rail locking assembly includes a connecting cylinder 20, which is bolted to the harmonic reducer 26. The EDC shaft 23 is bolted to the guide rail plate 21, and the guide rail plate 21 is fixed to the connecting cylinder 20 with bolts and positioned with locating pins. An ultra-thin bearing 22, a spacer 25, and a flat needle roller bearing 24 are installed between the EDC shaft 23 and the connecting cylinder 20, allowing the mirror tube fixing guide rail to rotate freely.

[0034] like Figures 6-7 As shown, the equatorial mount body 10 can be detached and mounted on the fixed support simulation 16 or the tripod 17.

[0035] This device is used for outdoor observation and photography of celestial bodies. When using this device, first fix the base 3 to the tripod to secure the device at the desired operating height. Then, fix the equatorial mount body 10 to the RA mounting base 9 using the locking screws 12. Next, rotate the latitude adjustment screw 4 counterclockwise, causing the latitude adjustment positioning block 41 to slide outwards. Since the latitude adjustment positioning block 41 passes through the adjustment plate 7, its outward sliding motion causes the adjustment plate 7 to rotate upwards, which in turn causes the RA support base 8, which is fixed to the adjustment plate 7, to rotate upwards, thus adjusting the device's pitch angle. After the device is adjusted to the predetermined angle, rotate the latitude fixing screws 5 on both sides of the device clockwise, causing them to screw inwards. This causes the latitude fixing screws 5 to press against the adjustment plate 7, thus fixing the adjustment plate 7 and the RA support base 8. Then, install the observation or imaging equipment on the equatorial mount 10, and pass the connecting cable of the equipment through the T-shaped through hole of the equatorial mount 10 and the longitudinal through hole of the RA support 8. Then connect the connecting cable to the device, and limit the connecting cable through the T-shaped through hole and the longitudinal through hole to avoid the connecting cable from getting tangled when the equatorial mount 10 drives the device to rotate. Finally, start the device to enter the working state.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
