Description

Technical Field

[0001] The present invention relates to the technical field of telescopes, and in particular, to an astronomical telescope. Background Art

[0002] An astronomical telescope is an important tool for observing celestial bodies. When using an astronomical telescope to observe celestial bodies, it is necessary to have a certain understanding of the positions of various celestial bodies. Otherwise, it is very difficult to accurately find the celestial body to be observed. With the popularization of astronomical telescopes, many users such as ordinary astronomy enthusiasts and teenagers do not fully possess the corresponding astronomical knowledge and are difficult to accurately find the celestial body they want to observe through an astronomical telescope, which is inconvenient to use. Currently, positioning software that can locate celestial bodies has emerged on mobile devices such as mobile phones. These positioning software use the GPS navigation system to determine the orientation of the mobile phone, and then display the names and distributions of celestial bodies in the corresponding orientations, providing convenience for users to find the positions of celestial bodies and understand astronomical knowledge.

[0003] For example, Chinese Patent Publication No. CN205427311U discloses an astronomical telescope. By providing a navigation bracket for placing a mobile phone on the main body of the astronomical telescope, it is convenient for an observer to determine the azimuth of a celestial body through the mobile phone. When the observer needs to use the mobile phone to photograph a celestial body, the connecting cylinder on the navigation bracket can also be connected to the eyepiece. Since the connecting cylinder is opposite to the camera of the mobile phone, the camera of the mobile phone can be used to photograph the celestial body. However, in the actual use process, when the observer wants to photograph a celestial body, the navigation bracket needs to be removed first and then installed at the eyepiece. During the removal and installation process, various fasteners need to be loosened and tightened, and the operation is complex, which undoubtedly wastes a lot of time; moreover, the connecting cylinder is directly sleeved on the eyepiece, and the stability is poor, and the mobile phone is not fixed firmly, so there may be a situation of blurred photography.

[0027] The following specific implementation details provide various different embodiments or examples for implementing the present invention. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present invention and do not represent a specific relationship between the different embodiments and / or structures being discussed.

[0028] As Figures 1 - 10 shown, an astronomical telescope includes a main mirror body 1, an objective lens 2, an eyepiece 3, a finder scope 12, a focusing cylinder 4, and a focusing assembly 5 for driving the focusing cylinder 4 to move axially forward and backward relative to the main mirror body 1, a tripod 111 for supporting the main mirror body 1, a fixing bracket 6 provided on the main mirror body 1, a vertical rod 7 capable of swinging in the front-back direction provided on one side of the fixing bracket 6, a sliding sleeve 8 slidably sleeved on the vertical rod 7 along its length direction, a support base 9 rotatably mounted on one side of the sliding sleeve 8, a clamping assembly 10 for clamping a mobile phone provided on the support base 9, an observation cylinder 11 provided on the clamping assembly 10, one end of the observation cylinder 11 being capable of corresponding to the camera of the mobile phone and the other end being capable of being inserted into the eyepiece 3, the support base 9 being detachably mounted on the fixing bracket 6, and when the support base 9 is detached from the fixing bracket 6, the observation cylinder 11 can follow the swing of the vertical rod 7 and the rotation of the support base 9, so that one end of the observation cylinder 11 is inserted into the eyepiece 3.

[0029] According to the above structure, when an observer needs to use the mobile phone for celestial positioning, the mobile phone is clamped by the clamping assembly 10, and then the support base 9 can be directly mounted on the fixing bracket 6. However, when the observer needs to use the mobile phone to photograph celestial bodies, the support base 9 is detached from the fixing bracket 6, then the vertical rod 7 is directly swung, and through the rotation of the support base 9, one end of the observation cylinder 11 is inserted into the eyepiece 3 to achieve the connection between the observation cylinder 11 and the eyepiece 3, which is relatively convenient to use. Additionally, while the vertical rod 7 is used to guide the movement of the support base 9, it can also play a role in supporting and fixing the support base 9, so that after the support base 9 is mounted on the fixing seat 6, or after the observation cylinder 11 is mounted on the eyepiece 3, the stability and safety of the mobile phone fixation are improved, and at the same time, the situation of blurred photography is avoided.

[0030] See Figure 3 、 Figure 5As shown, a U-shaped frame 21 is provided on one side of the fixing bracket 6. A rotating seat 22 is rotatably installed at the outer end of the U-shaped frame 21. One end of the vertical rod 7 is fixedly provided on the rotating seat 22. The rotating shaft 23 of the rotating seat 22 passes through the U-shaped frame 21 and has an external thread on the outer wall. The external thread is threadedly connected to a locking knob 25. That is to say, by screwing the locking knob 25, the U-shaped frame 21 and the rotating seat 22 can be fixedly connected or can be rotated and adjusted relative to each other. The structure is simple and the operation is convenient, further greatly improving the stability and safety after the mobile phone is fixed.

[0031] Further, a bolt column 31 is provided on one side of the sliding sleeve 8. A first locking bolt 32 is threadedly connected to the outer end of the bolt column 31. One end of the first locking bolt 32 can pass through the sliding sleeve 8 and abut against the vertical rod 7. By tightening the first locking bolt 32, the sliding sleeve 8 is fixed on the vertical rod 7, or the first locking bolt 32 is loosened to achieve unlocking.

[0032] See Figure 3 、 Figure 5 As shown, the clamping assembly 10 includes a vertical plate 41 fixedly provided on the support base 9. A fixed clamping piece 42 is fixed at the lower end of the vertical plate 41. An elastic clamping piece 43 is telescopically arranged at the upper end of the vertical plate 41. The observation cylinder 11 is arranged on the vertical plate 41. This clamping assembly 10 is a conventional existing design and will not be elaborated in detail here.

[0033] Further, an opening 51 is provided at the middle position of the vertical plate 41. Vertical guide rails 52 are provided on the left and right sides of the opening 51. A sliding plate 53 slides between the two vertical guide rails 52. The observation cylinder 11 is arranged on the sliding plate 53. A second locking bolt 54 is also threadedly connected to the sliding plate 53. One end of the second locking bolt 54 can pass through the sliding plate 53 and abut against the vertical guide rail 52. Thus, the observation cylinder 11 can be moved so that the mobile phone camera is aligned with the observation cylinder 11 for shooting or video recording, and thus it can be adapted to clamp and use mobile phones of different models.

[0034] See Figures 3 - 6 As shown, an installation plane 61 is provided on the upper side of the fixing bracket 6. A connecting plate 62 is provided on the lower side of the support base 9. A plurality of positioning columns 63 are arranged at intervals on the installation plane 61. A plurality of positioning holes 64 corresponding to the positioning columns 63 are provided on the connecting plate 62.

[0035] Of course, the fixing bracket 6 is a conventional existing design and can be a hoop or the like.

[0036] Further, a locking seat 71 is provided on one side of the installation plane 61. A locking plate 72 is telescopically movable on one side of the locking seat 71. One end of the locking plate 72 extends out of the locking seat 71 and a locking notch 73 is formed between the locking plate 72 and the installation plane 61. When the positioning post 63 is inserted into the positioning hole 64, the connecting plate 62 is locked in the locking notch 73. A first spring 74 is further provided in the locking seat 71 to keep one end of the locking plate 72 extending outwards to form the locking notch 73. The other end of the locking plate 72 extends out of the locking seat 71 and is provided with a dial plate 75.

[0037] When installing the support seat 9, the vertical rod 7 can be kept in a vertical state first, and then the support seat 9 can be directly driven to slide down along the vertical rod 7 through the sliding sleeve 8. The positioning hole 64 on the connecting plate 62 is inserted corresponding to the positioning post 63 on the installation plane 61. Then, the connecting plate 62 is snapped into the locking notch 73 to fix the support seat 9. The operation is extremely simple and convenient. However, the vertical rod 7 is also fixed by the lock button 25, so that the support seat 9 is doubly locked, greatly improving the stability when using the mobile phone. When detaching the support seat 9, directly pull the dial plate 75 to retract the locking plate 72 into the locking seat 71, so that the support seat 9 can be directly detached upwards.

[0038] When shooting celestial bodies is needed, the vertical rod 7 can be directly rotated to swing the support seat 9 towards the eyepiece 3. Then, by rotating the support seat 9, the observation cylinder 11 is set downwards and sleeved and snapped onto the eyepiece 3 to realize the connection between the observation cylinder 11 and the eyepiece 3. Finally, the vertical rod 7 is fixed by the lock button 25, greatly improving the stability when using the mobile phone.

[0039] The focusing seat is a component used for focusing on an astronomical telescope. Users can observe celestial bodies more clearly by adjusting the focal length. At present, the adjustment method of the focusing seat on the market realizes the forward and backward movement of the focusing seat only through the cooperation of gears and racks. This structure is simple and easy to operate, but it has no locking function, and the focusing seat is easy to loosen, resulting in unstable focal length. Therefore, to solve this problem, the present invention also proposes a focusing structure capable of having a locking structure.

[0040] See Figures 7 - 10As shown, a connecting cylinder 81 is provided at the rear end of the main lens barrel 1. The focusing assembly 5 is arranged on the connecting cylinder 81, and the focusing cylinder 4 is movably arranged back and forth at the rear end of the connecting cylinder 81. Among them, the focusing assembly 5 includes a housing 82 arranged on the lower side of the connecting cylinder 81. A gear support plate 83 is arranged in the housing 82. A first rotating shaft 84 is rotatably installed on one side of the gear support plate 83. A gear 85 is fixedly sleeved on the first rotating shaft 84. A rack 86 that can mesh with the gear 85 is arranged on the lower side of the focusing cylinder 4. A brake assembly and an adjustment driving assembly are also arranged in the housing 82. The brake assembly is used to brake and fix the gear 85, and the adjustment driving assembly can first unlock the brake assembly and then drive the gear 85 to rotate.

[0041] That is to say, the gear 85 can be braked and fixed by the brake assembly, improving the stability of the focusing cylinder 4. When focusing operation is required, the brake assembly can be unlocked by the adjustment driving assembly first, and then the gear 85 can be driven to rotate for focusing work.

[0042] Furthermore, the brake assembly includes swing plates 91 hinged to both sides of the gear 85 at intervals in the front and rear directions. A brake rubber 92 is arranged at one end of the swing plate 91, and a second spring 93 for keeping the brake rubber 92 abutted against the end of the gear 85 is arranged at the other end.

[0043] The adjustment driving assembly includes a square column 100 movably penetrating through the axis of the first rotating shaft 84. A second rotating shaft 101 is rotatably installed at one end of the square column 100. A rotating disk 102 is rotatably sleeved on the second rotating shaft 101. The rotating disk 102 is arranged between the two swing plates 91. An insertion block 103 is arranged in the housing 82. The other end of the second rotating shaft 101 can be movably inserted into the insertion block 103. An unlocking plate 104 is arranged at one end of the swing plate 91 close to the brake rubber 92. One end of the unlocking plate 104 abuts against the rotating disk 102. A third rotating shaft 105 is arranged at the other end of the square column 100. One end of the third rotating shaft 105 extends out of the housing 82 and is provided with a knob 106.

[0044] A movable groove 200 is provided in the third rotating shaft 105 along its radial direction. A cross plate 201 is movably arranged in the movable groove 200. A locking block 202 is arranged at one end of the cross plate 201, and a pressing block 203 is arranged at the other end. One end of the locking block 202 extends out of the third rotating shaft 105 movably, and one end abuts against the outer wall of the housing 82, so as to limit the movement of the third rotating shaft 105 towards the inside of the housing 82. One end of the pressing block 203 extends out of the knob 106. A guide post 204 for guiding the movement of the cross plate 201 is further arranged in the movable groove 200. A third spring 205 for keeping the locking block 202 and the pressing block 203 extending outwards is sleeved outside the guide post 204.

[0045] The focusing principle is as follows:

[0046] First, press the pressing block 203. The locking block 202 is driven by the cross plate 201 to retract into the third rotating shaft 105. At this time, the third rotating shaft 105 can be pushed into the housing 82. The third rotating shaft 105 drives the square column 100, the second rotating shaft 101, and the rotating disc 102 to move. The rotating disc 102 will push open the unlocking plate 104, and the swing plate 91 swings. The brake rubber 92 disengages from the gear 85 (as Figure 10 shown). At this time, the driving knob 106 can be rotated to drive the third rotating shaft 105, the square column 100, and the gear 85 to rotate. The gear 85 meshes with the rack 86, so that the focusing cylinder 4 can move back and forth to complete the focusing work. After the focusing is completed, the third rotating shaft 105 moves outwards and resets. Under the action of the second spring 93, the brake rubber 92 at one end of the swing plate 91 abuts against the end face of the gear 85, so as to lock the gear 85. The locking block 202 on the third rotating shaft 105 extends out and abuts against the outer wall of the housing 82, restricting the inward movement of the third rotating shaft 105, greatly improving the stability after focusing.
