Description

Technical Field

[0001] The present invention relates to the technical field of astronomical observation, in particular to a mounting device for a harmonic equatorial telescope. Background Art

[0002] Theodolites use a horizontal plus elevation coordinate system, which overcomes the effects of the Earth's rotation on astronomical observations. Compared to German equatorial mounts, theodolites are more ergonomically suited for visual observation, specifically for determining the up, down, left, and right positions of target objects. Traditional theodolites are specialized devices and difficult to use as German equatorial mounts. The newer harmonic equatorial mount supports both German equatorial and theodolite modes. However, in theodolite mode, the telescope is mounted on the side of the device, shifting the center of gravity away from the tripod. This places high stress on the device's support structure, making it unstable and difficult to mount binoculars. Furthermore, the side-mounted design is not ergonomic, making it more difficult to use than traditional theodolites.

[0003] In side-mounted altazimuth mode, the equatorial mount base is adjusted to 90° elevation, meaning the right ascension axis is 90° to the horizontal. In this mode, the right ascension axis's rotational axis is converted to a horizontal rotation mechanism, while the declination axis's rotational axis is converted to a pitch rotation mechanism. This creates significant stress on the base's elevation mechanism. Furthermore, after a 180° horizontal rotation, the forces acting on the elevation support structure reverse, causing elevation displacement and affecting tracking accuracy. When the telescope is side-mounted, the center of mass deviates significantly from the tripod's center. This poses a risk of tripod tipping when using a massive telescope. Safe observation requires a heavier counterweight or a tripod with a higher load capacity, compromising the device's portability. Furthermore, because the declination axis load is much smaller than the right ascension axis load in the German-style equatorial mount mode, the declination axis reducer is typically designed with a much smaller torque load capacity than the declination axis mechanism. However, in side-mounted altazimuth mode, the pitch axis reducer (declination axis) experiences a higher torque load, while the right ascension axis reducer experiences almost no torque load.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The purpose of the present invention is to provide a harmonic equatorial telescope mounting device to solve the technical problems that the existing equatorial mount body is prone to overturning and is not suitable for the installation of binoculars.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-9As shown, the present invention provides a harmonic equatorial telescope mounting device 100, comprising an equatorial mount body 1, an upper mounting support plate 3, a side support mechanism and a mounting base 2. The declination axis end face of the equatorial mount body 1 is detachably connected to the upper end of the mounting base 2. The lower end of the mounting base 2 is provided with a tripod interface and is used to be mounted on a tripod 300, thereby facilitating the support of the equatorial mount body 1 by the tripod 300. The upper mounting support plate 3 is detachably connected to the elevation base 9 of the equatorial mount body 1. The elevation adjustment knob 12 and the horizontal adjustment knob 11 on the equatorial mount body 1 are used to adjust the position of the upper mounting support plate 3 relative to the equatorial mount body 1 and lock it, and the correct position is confirmed by scale marks to ensure installation accuracy and stability. Among them, elevation and horizontal adjustment are functions possessed by the equatorial mount itself, and different equatorial mounts have different structures. And the type of adjustment mechanism used for a specific equatorial mount can be selected according to actual needs. In the theodolite telescope mounting mode, the right ascension axis reducer is responsible for pitch rotation, and the declination axis reducer is responsible for horizontal rotation. The upper support plate 3 is used to install the telescope mounting seat, and the monocular telescope 200 or binoculars 400 are installed on the telescope mounting seat, and the telescope mounting interface is arranged near the central axis of the tripod 300 mounting flange, so that the comprehensive center of mass of the equipment will fall near the support center of the tripod 300, and there is no risk of overturning. The side support mechanism is installed on the side of the upper support plate 3 away from the elevation base 9, and plays a supporting role on one side of the equatorial mount body 1, so that when it is used for the installation of a telescope with a larger mass, the structural stability can be enhanced by the side support mechanism, so it is also suitable for the installation of binoculars 400. At the same time, adjust the elevation angle of the equatorial mount base to 0°, convert the declination axis rotation axis in the German equatorial mount mode to the horizontal rotation axis of the theodolite, and convert the right ascension axis in the German equatorial mount mode to the pitch rotation axis. Under this structure, the elevation angle force of the equatorial mount always remains in the same direction, and the elevation angle locking is more stable.

[0032] The cam 6 is connected to the upper support plate 3 by a screw thread, and the ...

[0033] The horizontal ejector mechanism 6 includes an ejector mounting seat 601, a locking handle 602, a locking block 603, an ejector 606, an ejector locking member 608, an elastic member 605 and a handle 607. The ejector mounting seat 601 is provided with a vertical hole 604, and the vertical hole 604 is used for the vertical support shaft 5 to pass through. The locking handle 602 is connected to the locking block 603, and the locking block 603 is located in the ejector mounting seat 601 and is arranged on one side close to the vertical hole 604. The locking handle 602 is used to drive the locking block 60 3 action and locks the vertical support shaft 5, and then after the vertical support shaft 5 is moved into position, the vertical support shaft 5 can be locked to fix its position and realize a stable connection between the vertical support shaft 5 and the ejector mounting seat 601. The locking handle 602 and the locking block 603 are common structures. For example, they can be structures used for locking the spindle of a drilling machine or a milling machine. One end of the elastic member 605 is fixed to the ejector mounting seat 601 near the other side of the vertical hole 604, and the other end of the elastic member 605 is fixed to the ejector mounting seat 601. The pin 606 abuts against the pin 606, so that when the ejector pin 606 moves in the direction close to the elastic member 605, it can squeeze the elastic member 605 and make the elastic member 605 accumulate force. When the ejector pin 606 is released, the elastic member 605 drives the ejector pin 606 to rebound under the action of the elastic restoring force. Preferably, the elastic member 605 is a spring, and a limiting ring 609 is provided on the side of the ejector mounting seat 601 close to the ejector support seat mechanism 7. The ejector pin 606 is limited in the limiting ring 609 and prevents the ejector pin 606 from 6 falls off the thimble mounting seat 601, and the end of the thimble 606 close to the thimble supporting seat mechanism 7 extends out of the thimble mounting seat 601. The handle 607 is installed on the end of the thimble 606 close to the thimble supporting seat mechanism 7 and is used to drive the thimble 606 to move back and forth in the thimble mounting seat 601 in the direction away from or close to the thimble supporting seat mechanism 7. The thimble locking member 608 can pass through the thimble mounting seat 601 and lock the thimble 606, thereby fixing the position of the thimble 606. When the telescope is in the heavy-duty mode, the locking handle 602 and the locking block 603 are used to lock the vertical support shaft 5, and the ejector pin 606 is locked by the ejector pin locking piece 608. The ejector pin 606 is then locked and the ejector pin support mechanism 7 is adjusted to generate a pre-tightening force between the ejector pin 606 and the ejector pin support mechanism 7. At this point, the installation of the telescope is completed in the heavy-duty mode.Since the side structure is supported by the ejector pin 606, when the pitch axis rotates, there will be no rotation obstruction due to the eccentricity between the rotation center of the side support and the pitch axis, and at the same time, the side support can be effectively provided.

[0034] The end of the ejector pin 606 close to the vertical support shaft 5 is a limiting cylinder, and one end of the elastic member 605 can extend into the limiting cylinder and abut against the inner bottom surface of the limiting cylinder, thereby guiding the elastic member 605 through the limiting cylinder to avoid affecting the provision of preload force.

[0035] The ejector pin locking member 608 is a nut, which can be threadedly connected to one side of the ejector pin mounting seat 601 and pass through the ejector pin mounting seat 601 to contact the ejector pin 606. Then, by tightening the nut, the ejector pin 606 is squeezed and locked.

[0036] The ejector pin support seat mechanism 7 includes an ejector pin support seat 702, a knob 701 and a planar thrust bearing 703. One end of the knob 701 extends into the support seat 8 and is threadedly connected to the support seat 8. The other end of the knob 701 is hollow inside and is connected to the ejector pin support seat 702 through the planar thrust bearing 703. The knob 701 and the ejector pin support seat 702 can rotate and realize the distance adjustment between the ejector pin support seat mechanism 7 and the equatorial mount body 1. The end of the ejector pin support seat 702 away from the planar thrust bearing 703 can abut against the horizontal ejector mechanism 6 so as to provide pre-tightening force to the ejector pin 606 by rotating the knob 701.

[0037] The end of the upper support plate 3, away from the side support mechanism, is connected to the elevation base 9 via a locking knob 10. The locking knob 10 passes through the upper support plate 3 and is connected to the elevation base 9. The locking knob 10 also compresses the upper support plate 3. A plurality of threaded holes 301 are provided in the middle of the upper support plate 3. These threaded holes 301 are used to connect to the telescope mount. These threaded holes 301 are located directly above the mounting base 2, allowing the telescope mounting interface to be positioned near the central axis of the tripod 300 mounting flange. This positions the overall center of mass near the support center of the tripod 300, eliminating the risk of tipping over. Furthermore, since the right ascension axis reducer is responsible for the pitch rotation of the device, the forces acting on the device in the upper-mounted theodolite mode are the same as those in the German equatorial mount mode.

[0038] The upper support plate 3 is provided with a plurality of mounting holes 302 on one side for mounting with the side support mechanism. The upper support plate 3 is connected with the side support mechanism by bolts passing through the mounting holes 302 and the side support mechanism in sequence, which facilitates assembly and disassembly and can meet different usage requirements.

[0039] The harmonic equatorial telescope mounting device 100 provided by the present invention has two different usage modes, namely a light-load mode and a heavy-load mode.

[0040] Light load mode (such as Figure 8shown):

[0041] The mounting base 2 is connected to the end face of the declination axis of the equatorial mount body 1 by means of bolts. The mounting base 2 has a tripod 300 interface and can be mounted on the tripod 300 .

[0042] The upper support plate 3 is connected to the elevation base 9 on the equatorial mount body 1 through a locking knob 10. By adjusting the elevation adjustment knob 12 and the horizontal adjustment knob 11 on the equatorial mount body 1, the upper support plate 3 and the equatorial mount body 1 are in the correct relative position and locked in position, and the correct position is confirmed by the scale mark.

[0043] The telescope mounting base is connected through the threaded hole 301 on the upper support plate 3 and the telescope is installed.

[0044] In this mode, the telescope (eg, the monocular telescope 200 ) can be installed by simply installing the upper support plate 3 , which is easy to operate and can give full play to the lightweight characteristics of the harmonic equatorial mount.

[0045] Overload mode (such as Figure 9 shown):

[0046] When the mass of the telescope is high (for example, when installing binoculars 400 ), the structural stability needs to be enhanced by a side support mechanism.

[0047] Similar to the light load mode, the mounting base 2 is connected to the declination axis end face of the equatorial mount body 1 by bolts. The mounting base 2 has a tripod 300 interface and can be mounted on the tripod 300.

[0048] The upper support plate 3 is connected to the elevation base 9 on the equatorial mount body 1 via a locking knob 10. By adjusting the elevation adjustment knob 12 and the horizontal adjustment knob 11 on the equatorial mount body 1, the upper support plate 3 and the equatorial mount body 1 are in the correct relative position and locked in place, and the correct position is confirmed by the scale mark.

[0049] A mounting hole 302 is provided between the upper attachment side support plate 4 and the upper attachment support plate 3 , which can be connected by screws.

[0050] The vertical support shaft 5 is connected to the upper side support plate 4 through threads, and then the side support mechanism provides auxiliary support to reduce the risk of overturning.

[0051] The various parts can be quickly disassembled for easy storage. In addition, the installation of side supports in the form of ejector pins in this mode can avoid rotation obstruction caused by the misalignment of the side support rotation axis and the rotation axis of the equatorial mount body 1. The ejector pin structure can ensure normal rotation of the structure under slight misalignment while providing effective support.

[0052] Whether in light load mode or heavy load mode, the entire mount can be installed with the help of the existing structure of the mount body 1, without the need to disassemble the parts of the mount body 1, making installation easy.

[0053] At the same time, the position adjustment of the upper support plate 3 can be performed with the aid of the existing adjustment mechanism of the equatorial mount body 1 , which is easy to use and applicable to harmonic equatorial mounts of various specifications.

[0054] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
