Description

Technical Field

[0001] The present invention relates to the technical field of telescopes, and in particular to a telescope secondary mirror adjustment mechanism. Background Art

[0002] The core components of a common Newtonian reflecting telescope include a primary mirror and a secondary mirror. The primary mirror is a spherical reflector whose main function is to converge light. Specifically, when light from a distant celestial object enters the telescope, it is first reflected by the primary mirror. This reflection process creates a converging effect, causing the light to focus on the secondary mirror. In this way, the primary mirror can effectively collect and converge light from distant celestial objects, thereby enhancing the telescope's imaging capabilities. The secondary mirror is a flat mirror whose main function is to reflect the light reflected from the primary mirror again so that it reaches the eyepiece. This design not only simplifies the structure of the telescope but also improves the efficiency and accuracy of observations.

[0003] In existing technology, when the lens barrel is horizontal, the secondary mirror is typically positioned at a 45° angle to the horizontal. This allows the secondary mirror to deflect light at a 90° angle, ensuring that light accurately enters the eyepiece, enabling precise observation and imaging of celestial bodies. The eyepiece is fixed to the side of the lens barrel. When the lens barrel rotates (for example, to track a celestial body), the eyepiece moves with it, requiring the user to frequently adjust their observation posture. Existing improvements include: a rotating secondary mirror design that compensates for lens barrel rotation, but this is complex (such as the "Nasmyth focus" system); and an eyepiece steering prism that uses prisms or optical fibers to guide light, but this is relatively costly.

[0004] Therefore, in order to solve the above technical problems existing in the prior art, a telescope secondary mirror adjustment mechanism is proposed. Summary of the Invention

[0005] The present invention provides a telescope secondary mirror adjustment mechanism, which has an additional plane reflector installed between the primary mirror and the secondary mirror. Through the synchronous rotation mechanism of the primary mirror and the intermediate plane reflector, the eyepiece position is ensured to remain constant when the lens barrel rotates. The observer can continuously track the target without moving, which significantly improves the observation comfort and efficiency. It solves the problem mentioned in the above background technology that the eyepiece of the traditional Newtonian reflecting telescope is fixed to the side of the lens barrel. When the lens barrel rotates around the optical axis to track the movement of celestial bodies, the position of the eyepiece changes accordingly. The observer needs to move his body or adjust the bracket frequently, resulting in observation interruption and reduced comfort, which is extremely inconvenient during long-term observation or photography. Existing solutions (such as rotating secondary mirrors or light-guiding prisms) have the problems of complex structure, high cost or large light loss.

[0006] The present invention provides the following technical solution: a telescope secondary mirror adjustment mechanism, comprising a lens barrel, wherein a spherical reflector, a first plane reflector, and an eyepiece are provided on the lens barrel, a second plane reflector is further provided between the spherical reflector and the first plane reflector, and light is reflected by the spherical reflector, the second plane reflector, and the first plane reflector in sequence before entering the eyepiece;

The lens barrel is provided with a second mounting seat. The first mounting seat is provided with a second rotating shaft, and the second rotating shaft is rotatably connected to the second mounting seat.

[0008] The first adjustment assembly further includes a transmission assembly, wherein the transmission assembly is configured to realize transmission between the first rotating shaft and the second rotating shaft at a transmission ratio of 1:1, thereby enabling the spherical reflector and the second plane reflector to rotate synchronously;

[0009] When the positions of the first plane reflector and the eyepiece are kept fixed and the angle of the first mounting seat is adjusted, the path of the light reflected by the first plane reflector to the eyepiece remains unchanged.

[0010] As an optional solution to the secondary mirror adjustment mechanism of a telescope described in the present invention, a light-blocking plate is also provided in the lens barrel, and the light-blocking plate is used to block the light directly reflected by the spherical reflector to the first plane reflector. A focusing seat and a finder mirror are also provided on the lens barrel.

[0013] As an optional solution of the secondary mirror adjustment mechanism of a telescope described in the present invention, the first adjustment component also includes a driving component, the driving component includes a third mounting seat arranged on the lens barrel, a worm gear is provided on the third rotating shaft, a worm is rotatably provided on the third mounting seat, the worm gear is engaged with the worm, and the first mounting seat is elastically connected to the lens barrel through a spring.

[0014] As an optional solution of the telescope secondary mirror adjustment mechanism described in the present invention, a fixing seat is provided on the third mounting seat, a sliding groove is provided on the worm, and a square rod is slidably provided in the sliding groove.

[0015] As an optional solution of the telescope secondary mirror adjustment mechanism described in the present invention, the square rod is provided with an insert block, the fixing seat is provided with a slot and an oblique groove, the slot and the oblique groove are connected, and the insert block is movably inserted into the slot.

[0016] As an optional solution of the secondary mirror adjustment mechanism of a telescope described in the present invention, a second adjustment component is also provided on the lens barrel, the second adjustment component includes a fourth mounting seat provided on the lens barrel, a fifth mounting seat is installed on the fourth mounting seat by a first bolt, and the first plane reflector is installed on the fifth mounting seat.

[0017] As an optional solution of the telescope secondary mirror adjustment mechanism described in the present invention, several second bolts are circumferentially arranged on the fourth mounting seat, several of the second bolts are connected to the fifth mounting seat, and several of the second bolts are provided with adjustment nuts.

[0018] As an optional solution of the telescope secondary mirror adjustment mechanism described in the present invention, the telescope secondary mirror adjustment mechanism further includes a tripod, an equatorial mount is installed on the tripod, and the lens barrel is installed on the equatorial mount.

[0019] The present invention has the following beneficial effects:

[0020] 1. The telescope's secondary mirror adjustment mechanism achieves eyepiece fixation through synchronous rotation of the intermediate mirror. It has a relatively simple structure and controllable cost, making it suitable for small and medium-sized telescopes. Through the synchronous rotation mechanism of the primary mirror and the intermediate plane mirror, within a certain range, only the angle of the primary mirror needs to be adjusted to align with the observation target, while the eyepiece position remains constant. The observer can continuously track the target without moving, significantly improving observation comfort and efficiency.

[0021] 2. This telescope's secondary mirror adjustment mechanism differs from the fixed secondary mirror of traditional Newtonian telescopes. By incorporating a synchronously rotating intermediate plane mirror, this system dynamically compensates for optical path changes caused by tube rotation, thereby achieving a fixed eyepiece position. Compared to complex light-guiding prisms or electronic compensation systems, this solution requires only a single plane mirror and mechanical linkage, resulting in low cost and ease of mass production.

[0022] 3. The telescope's secondary mirror adjustment mechanism utilizes a worm gear mechanism to adjust the primary and intermediate mirrors for ease of operation, with a self-locking mechanism to secure the mirror angles. For resetting, a snap-fit ​​mechanism consisting of an inclined slot, a slot, and an insert allows the worm gear to be roughly adjusted to near its initial position, and then precisely reset by simply pressing the square rod on the worm gear.

DETAILED DESCRIPTION

[0034] 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.

[0035] For example 1, please refer to Figures 1-10 A telescope secondary mirror adjustment mechanism includes a lens barrel 100, on which a spherical reflector 110, a first plane reflector 120 and an eyepiece 130 are arranged. A second plane reflector 140 is also arranged between the spherical reflector 110 and the first plane reflector 120. Light is reflected by the spherical reflector 110, the second plane reflector 140 and the first plane reflector 120 in sequence and then enters the eyepiece 130.

[0036] The lens barrel 100 is also provided with a first adjustment assembly 200, which includes a first rotating shaft 210 and a first mounting seat 220. The first rotating shaft 210 is provided on the second plane reflector 140, and the first rotating shaft 210 is rotatably connected to the lens barrel 100. The spherical reflector 110 is provided on the first mounting seat 220. The lens barrel 100 is provided with a second mounting seat 230, and the first mounting seat 220 is provided with a second rotating shaft 240, and the second rotating shaft 240 is rotatably connected to the second mounting seat 230.

[0037] The first adjustment assembly 200 further includes a transmission assembly 250 , which is used to realize transmission between the first rotating shaft 210 and the second rotating shaft 240 at a transmission ratio of 1:1, thereby allowing the spherical reflector 110 and the second plane reflector 140 to maintain synchronous rotation.

[0038] When the positions of the first plane reflector 120 and the eyepiece 130 are kept fixed and the angle of the first mounting base 220 is adjusted, the path of the light reflected from the first plane reflector 120 to the eyepiece 130 remains unchanged.

[0039] The telescope secondary mirror adjustment mechanism further includes a tripod 400 , an equatorial mount 500 is mounted on the tripod 400 , and the lens barrel 100 is mounted on the equatorial mount 500 .

[0040] In this embodiment, a tripod 400 is used to support the entire telescope, and an equatorial mount 500 is used to adjust the position of the lens barrel 100 in terms of longitude and latitude. The specific structure of the equatorial mount 500 may include a declination axis fine-tuning rod, a latitude adjustment screw, a right ascension axis fine-tuning rod, a weight, etc. A spherical reflector 110 serves as a primary mirror, and a first plane reflector 120 and a second plane reflector 140 serve as secondary mirrors.

[0041] In a conventional Newtonian reflecting telescope, when the lens tube 100 is Figure 2 The image is shown when the lens is positioned horizontally with the lens opening facing left. Spherical reflector 110 is positioned vertically on the far right side, while in the prior art, first plane reflector 120 is mounted at a 45° angle to the left of the horizontal. Eyepiece 130 is vertically facing upward. Light entering the lens opening is reflected by spherical reflector 110 and then by first plane reflector 120. First plane reflector 120 then reflects the light vertically upward at a 90° angle to eyepiece 130, where an image is formed. To adjust the viewing angle for different celestial objects or to track them, the entire lens barrel 100 must be rotated in both longitude and latitude.

[0042] On this basis, an improvement is made by adding a second plane reflector 140 between the spherical reflector 110 and the first plane reflector 120, and the angle between the first plane reflector 120 and the horizontal line may not be 45°. Figure 9 As shown, it is assumed that a certain light ray reflected by the vertical spherical reflector 110 is horizontally to the left along the a1 path. At this time, the angle between the second plane reflector 140 and the horizontal line is 15°, that is, the incident angle of the light ray to the second plane reflector 140 is 15°, and the angle between the incident light ray and the reflected light ray is 150°.

[0043] At this time, the light reflected by the second plane reflector 140 reaches the first plane reflector 120 along the path a2. The angle between the first plane reflector 120 and the horizontal line is 60°. At this time, the light reflected by the first plane reflector 120 will reach the eyepiece 130 vertically upward along the path a3.

[0044] Within a certain angle range, the position of the lens barrel 100 and the eyepiece 130 does not need to be changed, and the user does not need to adjust the observation posture. Instead, the observation target can be adjusted by rotating the spherical mirror 110 in the front-back direction. Figure 10 As shown, it is assumed that the spherical reflector 110 is rotated 1° counterclockwise based on the rotation axis of its center position. Figure 9 The light reflected from the same position is along Figure 10 Path a1 in the image is emitted at an angle inclined to the lower left. At this time, the second plane reflector 140 is controlled to rotate 1° counterclockwise based on its center position. The angle between the second plane reflector 140 and the horizontal line is 14°. The incident angle of the light from path a1 on the second plane reflector 140 is still 15°. The angle between the reflected light from path a2 and the light from path a1 is still 150°. The final reflected light from path a3 is still vertically upward. The image of the target can be observed by adjusting the eyepiece 130. There is no need to change the positions of the first plane reflector 120 and the eyepiece 130.

[0045] The adjustable range of the first mounting base 220 can be obtained by specific calculation. Within a certain observation target adjustment range, the entire lens barrel 100 and the observation posture do not need to be adjusted.

[0046] Example 2: This example is an improvement based on Example 1. For details, please refer to Figures 1-10 A light blocking plate 150 is further provided in the lens barrel 100 , and the light blocking plate 150 is used to block the light directly reflected by the spherical reflector 110 to the first plane reflector 120 . A focusing seat 160 and a finderscope 170 are also provided on the lens barrel 100 .

[0047] In this embodiment, a light baffle 150 is further provided between the spherical reflector 110 and the first plane reflector 120. The light baffle 150 is installed in the lens barrel 100. Its function is to block the light that may be directly reflected by the spherical reflector 110 to the first plane reflector 120, so that the light can only be reflected by the spherical reflector 110 to the second plane reflector 140 and then reflected to the first plane reflector 120.

[0048] The light barrier 150 may be circular, and its diameter may be as follows: Figure 9 and Figure 10As shown in FIG, a light blocking plate 150 is installed at a position on the line connecting the upper and lower points of the spherical reflector 110 and the upper and lower points of the first plane reflector 120. The diameter of the light blocking plate 150 is greater than or equal to the length of the perpendicular line at the position.

[0049] The focuser 160 and the finderscope 170 are conventional components of a telescope and are not described in detail. The focuser 160 can be adjusted in two ways: coarse and fine, and is used to change the length of the eyepiece 130, thereby adjusting the focus of the image.

[0050] Example 3: This example is an improvement based on Example 1. For details, please refer to Figure 1-Figure 5 The transmission assembly 250 includes a third rotating shaft 251 rotatably arranged on the lens barrel 100, a first pulley 252 is arranged on the third rotating shaft 251, a second pulley 253 is arranged on the first rotating shaft 210, and the first pulley 252 is connected to the second pulley 253 through a first transmission belt 254.

[0051] A third pulley 255 is also provided on the third rotating shaft 251, and a fourth pulley 256 is provided on the second rotating shaft 240. The third pulley 255 is connected to the fourth pulley 256 through a second transmission belt 257. The diameters of the first pulley 252, the second pulley 253, the third pulley 255 and the fourth pulley 256 are equal.

[0052] In this embodiment, to achieve synchronous rotation of the spherical reflector 110 and the second plane reflector 140, the front and rear ends of the second plane reflector 140 are first connected to the first rotating shaft 210. The first mounting base 220 is rotatably mounted on the second mounting base 230 via the second rotating shaft 240. By driving the third rotating shaft 251 to rotate, the second plane reflector 140 can be driven to rotate synchronously via the first pulley 252, the first transmission belt 254, and the second pulley 253. At the same time, the third rotating shaft 251 drives the second rotating shaft 240 to rotate via the third pulley 255, the second transmission belt 257, and the fourth pulley 256. The specifications of the pulleys are consistent, and the transmission ratio between the first rotating shaft 210 and the second rotating shaft 240 is 1:1.

[0053] Example 4: This example is an improvement made on the basis of Example 3. For details, please refer to Figure 3-Figure 6 The first adjustment assembly 200 also includes a driving assembly 260, which includes a third mounting seat 261 arranged on the lens barrel 100, a worm gear 262 provided on the third rotating shaft 251, a worm 263 rotatably provided on the third mounting seat 261, the worm gear 262 engages with the worm 263, and the first mounting seat 220 is elastically connected to the lens barrel 100 through a spring 270.

[0054] In this embodiment, in order to facilitate operation and fix the adjusted position of the first mounting base 220, the worm gear 262 and the third rotating shaft 251 are rotated by rotating the worm 263. There is a self-locking between the worm gear 262 and the worm 263, and the worm gear 262 can only be driven by the worm 263 to rotate. After the angle of the spherical reflector 110 and the second plane reflector 140 is changed by rotating the worm 263, the positions of the spherical reflector 110 and the second plane reflector 140 remain unchanged when the worm 263 is not touched.

[0055] Example 5: This example is an improvement based on Example 4. For details, please refer to Figure 3-Figure 7 A fixing seat 264 is provided on the third mounting seat 261 , a sliding groove 265 is provided on the worm 263 , and a square rod 266 is slidably provided in the sliding groove 265 .

[0056] An insert block 267 is provided on the square rod 266 , and a slot 268 and an oblique groove 269 are provided in the fixing seat 264 . The slot 268 and the oblique groove 269 are connected, and the insert block 267 is movably inserted into the slot 268 .

[0057] In this embodiment, in order to facilitate the repositioning of the spherical reflector 110 and the second plane reflector 140 so that the spherical reflector 110 returns to its initial coaxial position with the lens barrel 100, the worm 263 is not directly screwed. Instead, the square rod 266 needs to be lifted upward to disengage the insert 267 from the slot 268. At this point, the slot 268 no longer limits the position of the insert 267 and the square rod 266.

[0058] At this time, the square rod 266 is twisted. Since the sliding groove 265 is a non-circular rectangle or other shape, the rotation of the square rod 266 will drive the worm 263 to rotate.

[0059] When resetting, after turning the square rod 266 to the approximate position, press the square rod 266 downward. At this time, the plug block 267 slides down along the inclined groove 269 and continues to press the square rod 266 downward. Since the edges of the slot 268 and the plug block 267 are curved, the curved edges contact each other, which will automatically cause the plug block 267 and the square rod 266 to deflect, so that the plug block 267 is accurately inserted into the slot 268, thereby realizing the precise resetting of the spherical reflector 110 and the second plane reflector 140.

[0060] The spring 270 is used to connect the lens barrel 100 and the first mounting seat 220 , and plays a role in strengthening the support for the first mounting seat 220 .

[0061] Example 6: This example is an improvement based on Example 1. For details, please refer to Figure 2-Figure 8A second adjustment assembly 300 is also provided on the lens barrel 100. The second adjustment assembly 300 includes a fourth mounting seat 310 provided on the lens barrel 100. A fifth mounting seat 330 is mounted on the fourth mounting seat 310 through a first bolt 320. The first plane reflector 120 is mounted on the fifth mounting seat 330.

[0062] A plurality of second bolts 340 are circumferentially provided on the fourth mounting seat 310 . The plurality of second bolts 340 are all connected to the fifth mounting seat 330 . Adjustment nuts 350 are provided on the plurality of second bolts 340 .

[0063] In this embodiment, the first plane reflector 120 and the fifth mounting base 330 are mounted on the fourth mounting base 310 by means of a first bolt 320. If it is observed during installation that the position of the first plane reflector 120 is incorrect, the position of the first plane reflector 120 can be fine-tuned by screwing several surrounding adjustment nuts 350.

[0064] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
