Description

Technical Field

[0001] This utility model relates to the field of astronomical telescope technology, and in particular to a primary mirror mount fixing device for a reflecting astronomical telescope. Background Technology

[0002] Reflecting telescopes, especially Newtonian reflecting telescopes, are widely used in astronomical observation and astrophotography due to their simple structure, low cost, and good observation results. They are very popular among astronomy enthusiasts. The core of the optical system of a Newtonian reflecting telescope consists of a primary mirror and a secondary mirror. The structural design of the primary mirror mount directly affects the imaging quality of the telescope. As a key optical lens, the primary mirror is not only heavy, but also easily deformed under external forces, which can lead to imaging deviations.

[0003] In existing technologies, primary mirror mounts typically use multiple side support points to support the primary mirror. Some use cap claws or annular caps to prevent the primary mirror from detaching, while others use side bolts to directly fix the primary mirror. This traditional structure has many drawbacks: Firstly, it is difficult to precisely control the gap on the side of the primary mirror during fixed installation. If the gap is too large, it will easily cause the primary mirror to wobble and become unstable. If the gap is too small, it may cause the primary mirror to be squeezed due to being too tight. Secondly, the contact surface of the main mirror is extremely small when the bolts directly support it. Even with the addition of shims, it is still easy to cause local deformation of the main mirror at the contact point, and the installation operation technique is extremely demanding. Third, the clamping force of the front cover claw or cover plate is difficult to control precisely, and improper force will directly cause deformation of the main lens; Fourth, traditional side supports are fixed installations or simple bolt adjustment structures, which are inconvenient to adjust, inefficient, and cannot be compatible with main mirrors of different diameters. The aforementioned problems result in some existing primary mirror mounts having insufficient stability, high installation difficulty, and easy deformation of the primary mirror, which seriously affects the imaging effect of astronomical photography and restricts the user experience of reflecting astronomical telescopes.

[0004] To address this, a primary mirror mounting device for a reflecting astronomical telescope is proposed. Utility Model Content

[0008] Preferably, both the pull screw and the push screw are threaded onto the support base. The pull screw abuts against one end of the support rod, and the push screw is symmetrically distributed at the top and bottom of the pull screw and abuts against the side of the support rod.

[0009] Preferably, a soft pad is fixedly connected to the surface of the support claw, and the soft pad has an arc-shaped structure.

[0010] Preferably, the curvature of the soft pad is adapted to the curvature of the outer peripheral surface of the main mirror body, and the surface of the soft pad is in close contact with the surface of the main mirror body.

[0018] 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.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: A primary mirror mount fixing device for a reflecting astronomical telescope includes a base plate 1, a side support assembly 3 is provided on the top of the base plate 1, the number of side support assemblies 3 is three and evenly distributed on the top of the base plate 1, a primary mirror body 4 is provided on the top of the base plate 1, and a cover plate 2 is provided on the top of the primary mirror body 4. The cover plate 2 is detachably connected to the side support assembly 3.

[0020] In this embodiment: the main mirror body 4 is placed on the bottom pad 5 on the top of the base plate 1. Three side support components 3 that are evenly surrounding the main mirror body 4 are fixed with external bolts through the mounting holes of the base plate 1. The support base 305 is fixed to the base plate 1. The support rod 302 is rotatably connected to the support base 305 via a rotating pin 304. Two support claws 301 are connected to the support rod 302 via rotating pins 304. The arc-shaped soft pads 6 on their surfaces are adapted to the outer circumference of the main mirror body 4. By adjusting the pull screws 307 and the symmetrical push screws 306 on the support base 305, the support claws 301 are moved by lever principle. After the six soft pads 6 come into contact with the surface of the main mirror body 4, the rotating pins 304 are locked with the pin fixing screws 303. The cover plate 2 is connected to the support base 305 by six evenly distributed connecting bolts 7. The height of the cover plate 2 is adjusted by turning the three evenly distributed adjusting screws 8 in conjunction with the connecting bolts 7. Finally, the main mirror body 4 is stably installed by the side support and the cover plate 2, avoiding shaking and deformation.

[0021] Specifically, such as Figure 4 As shown, the side support assembly 3 includes two support claws 301, a support rod 302, a pin fixing screw 303, four rotating pins 304, a support base 305, four push screws 306 and a pull screw 307. The support base 305 is fixedly connected to the base plate 1. The support rod 302 is rotatably connected to the support base 305 through the rotating pins 304. The two support claws 301 are respectively rotatably connected to the side of the support rod 302 away from the support base 305 through the rotating pins 304.

[0022] Specifically, such as Figure 4 As shown, the pull screw 307 and the push screw 306 are both threaded onto the support base 305. The pull screw 307 abuts against one end of the support rod 302, and the push screw 306 is symmetrically distributed at the top and bottom of the pull screw 307 and abuts against the side of the support rod 302.

[0023] Specifically, such as Figure 2 and Figure 5 As shown, a soft pad 6 is fixedly connected to the surface of the support claw 301, and the soft pad 6 has an arc-shaped structure.

[0024] Specifically, such as Figure 2 and Figure 5 As shown, the curvature of the soft pad 6 is adapted to the curvature of the outer peripheral surface of the main mirror body 4, and the surface of the soft pad 6 is in close contact with the surface of the main mirror body 4.

[0025] In this embodiment: the side support assembly 3 achieves the rotatable connection between the support rod 302 and the support base 305, and the support claw 301 and the support rod 302 through the rotating pin 304. With the symmetrically distributed push screws 306 and pull screws 307, the position of the support claw 301 can be flexibly adjusted. The arc-shaped soft pad 6 is adapted to and in close contact with the outer peripheral surface of the main mirror body 4 to form multi-point surface support, which not only avoids the deformation of the main mirror body 4 under force, but also improves the support stability and ensures the imaging quality.

[0026] Specifically, such as Figure 1 and Figure 6 As shown, the top of the cover plate 2 is provided with several connecting bolts 7 and several adjusting screws 8. The bottom of the connecting bolts 7 passes through the cover plate 2 and is threadedly connected to the support base 305. The adjusting screws 8 are threadedly connected inside the cover plate 2 and are positioned with their bottom facing the main mirror body 4.

[0027] Specifically, such as Figure 1 and Figure 6 As shown, there are six connecting bolts 7 and three adjusting screws 8. The six connecting bolts 7 and the three adjusting screws 8 are evenly distributed along the circumference of the cover plate 2.

[0028] Specifically, such as Figure 4 As shown, the rotating pin 304 is locked by the pin fixing screw 303, which is threaded into the support base 305 and abuts against the surface of the rotating pin 304.

[0029] In this embodiment: the connecting bolts 7 and the adjusting screws 8 work together to enable the cover plate 2 to be detachably installed and its height adjusted. The six sets of connecting bolts 7 and the three sets of adjusting screws 8 are evenly distributed to ensure that the cover plate 2 is subjected to balanced force. The pin fixing screws 303 lock the rotating pins 304 to prevent loosening after adjustment, further improving the overall stability of the device and reducing the difficulty of installation.

[0030] Specifically, such as Figure 2 As shown, the top of the base plate 1 has a mounting hole that mates with the support base 305. The support base 305 is fixedly connected to the base plate 1 by bolts. Several bottom pads 5 are fixedly connected to the top of the base plate 1. The bottom of the main mirror body 4 is in contact with the top of the bottom pads 5.

[0031] Specifically, such as Figure 4 As shown, the inner wall of the pin hole connecting the support claw 301 and the support rod 302 is provided with a lubricating layer, which is a polytetrafluoroethylene coating.

[0032] In this embodiment: the mounting holes on the base plate 1 facilitate the precise positioning and installation of the support base 305, and the bottom pad 5 prevents the main mirror body 4 from making rigid contact with the base plate 1.

[0033] Working principle: The main mirror body 4 is placed on the bottom pad 5 on the top of the base plate 1. Three evenly distributed side support components 3 are fixed by bolts through the mounting holes on the base plate 1, so that the three are arranged around the main mirror body 4. In the side support components 3, the support base 305 is fixedly connected to the base plate 1, the support rod 302 is rotatably connected to the support base 305 through the rotating pin 304, and the two support claws 301 are rotatably connected to the side of the support rod 302 away from the support base 305 through the rotating pin 304 respectively. The surface of the support claws 301 is fixed with arc-shaped soft pads 6 that are adapted to the curvature of the outer circumference of the main mirror body 4. By adjusting the pull screw 307 on the support base 305 and the push screws 306 symmetrically distributed on its top and bottom, the support rod 302 is driven to rotate around the rotating pin 304 by lever principle, which in turn drives the support claws 301 to move, so that the soft pads of the six support claws 301 are fixed. All plates 6 are tightly fitted to the outer circumferential surface of the main mirror body 4 to form surface contact support. After adjusting to the appropriate tightness, the locking pin 303 is used to press against the rotating pin 304 to achieve locking. Then, the cover plate 2 is detachably connected to the three support seats 305 by six circumferentially evenly distributed connecting bolts 7. The three circumferentially evenly distributed adjusting screws 8 on the cover plate 2 are screwed on, and the pulling force of the connecting bolts 7 is used to adjust the height of the cover plate 2, accurately controlling the gap between the cover plate 2 and the top of the main mirror body 4. Finally, through the multi-point surface contact support of the side support component 3 and the limiting effect of the cover plate 2, the main mirror body 4 is stably installed, avoiding shaking or deformation during use. This solves the problems of insufficient stability, difficult installation, and easy deformation of the main mirror in some existing main mirror mounts, which seriously affect the imaging effect of astronomical photography and restrict the user experience of reflecting astronomical telescopes.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
