Description

Technical Field

[0001] The present invention relates to the technical field of telescopes, and in particular to an all-plastic large-aperture wide-angle telescope. Background Art

[0002] In the field of telescopes, large-aperture, wide-angle telescopes are highly favored for astronomical and long-distance observations due to their ability to collect more light and provide a wider field of view. However, in the practical application of traditional large-aperture, wide-angle telescopes, the connection structure between the tripod and the main telescope directly affects the convenience and accuracy of observation operations. Currently, most telescopes on the market use a simple pivot connection method, where the main telescope is connected to the tripod's connection seat via a single pivot, achieving rough adjustment of the vertical angle. Although this structure is simple in design and low in manufacturing cost, it has obvious functional defects.

[0003] Due to the lack of a dedicated fine-tuning device, the observer is unable to fine-tune the angle of the main telescope after completing the initial angle adjustment. For example, when observing distant, stationary objects (such as ancient architectural details or landscapes), the initial adjustment may bring the object into view, but it is difficult to accurately align it with the center of the field of view. This lack of adjustment precision often results in the telescope being unable to achieve ideal observation conditions, greatly affecting the observing experience and the accuracy of data recording.

[0026] The following detailed description provides various embodiments or examples for implementing the present invention. Of course, these are merely examples or embodiments and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. Such repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the different embodiments and / or configurations discussed.

[0027] like Figures 1-9 The shown embodiment is an all-plastic large-aperture wide-angle telescope, comprising a main lens body 1, a tripod 2 and a connecting assembly for connecting the main lens body 1 and the tripod 2, wherein the connecting assembly comprises a first connecting seat 3 provided on the tripod 2, a cylindrical sleeve 4 being provided on the first connecting seat 3, an outer rotating cylinder 5 being rotatably mounted in the cylindrical sleeve 4, an inner rotating column 6 being coaxially rotatably mounted in the outer rotating cylinder 5, an avoidance groove 7 being provided on the outer wall of the outer rotating cylinder 5, a second connecting seat 8 being further provided on the main lens body 1, one end of the second connecting seat 8 being provided in the avoidance groove 7 and fixedly connected to the inner rotating column 6, a locking device and a fine-tuning device being further provided on the outer rotating cylinder 5, the locking device being used to lock the outer rotating cylinder 5 on the cylindrical sleeve 4, and the fine-tuning device being used to drive the inner rotating column 6 to rotate in the outer rotating cylinder 5.

[0028] According to the above structure, first, the outer rotating cylinder 5 rotates in the cylindrical sleeve 4, so that the upper and lower angles of the main mirror body 1 can be roughly adjusted; then, the fine-tuning device can be used to drive the inner rotating column 6 to rotate in the outer rotating cylinder 5. This design can achieve fine-tuning of the observation angle of the telescope; when the observer is observing, the fine-tuning device can accurately adjust the direction of the telescope, so that the target is clearly presented in the field of view, without missing any subtle observation details, which significantly improves the accuracy of observation. It is especially suitable for scenes such as astronomical observation and observation of details of distant targets that require extremely high observation accuracy.

[0029] In addition, the setting of the locking device can firmly lock the outer rotating cylinder 5 on the cylindrical sleeve 4; when the observer adjusts the angle of the telescope, it is fixed by the locking device, which can ensure that the telescope remains stable during the observation process, avoid angle deviation caused by external interference or accidental touch, ensure the stability and continuity of the observation process, and provide a strong guarantee for obtaining high-quality observation results.

[0030] The all-plastic large-aperture wide-angle telescope of the present invention further includes an objective lens 10 disposed at the front end of a main telescope body 1, a focusing tube 11 slidably disposed at the rear end of the main telescope body 1, an eyepiece 12 disposed on the focusing tube 11, and a finderscope 13 disposed on the main telescope body 1.

[0031] The above-mentioned main lens body 1, objective lens 10, focusing tube 11 and eyepiece 12 are all made of plastic material. Compared with traditional metal telescopes, the weight is significantly reduced, which makes it more convenient to carry outdoors and operate handheld for a long time. It is especially suitable for outdoor adventures, travel and sightseeing. In addition, plastic material has good corrosion resistance and impact resistance, and can adapt to complex environments such as humidity, dust, and large temperature differences. It reduces damage to the equipment due to rust or bumps, extends its service life, and reduces maintenance costs.

[0032] See also Figure 3 、 Figure 9 As shown, the locking device includes a button 21 provided on the front side of the outer rotating cylinder 5, a fixed block 22 is connected to one side of the button 21 and is located inside the outer rotating cylinder 5, a stop block 23 is movably extended out of the outer rotating cylinder 5 and is provided on the front side of the fixed block 22, a locking ring groove is provided on the inner wall of the cylindrical sleeve 4, and a first spring 25 is also provided at the inner end of the button 21, and the stop block 23 is abutted against the locking ring groove under the action of the first spring 25.

[0033] Specifically, the button 21 of the locking device is installed on the front side of the outer rotating cylinder 5, and the fixed block 22 on one side of the button 21 is located inside the outer rotating cylinder 5. The front side of the fixed block 22 extends out of the outer rotating cylinder 5 and is connected to the stop block 23; a locking ring groove is provided on the inner wall of the cylinder sleeve 4, and the first spring 25 at the inner end of the button 21 makes the stop block 23 rest against the locking ring groove; pressing the button 21 compresses the first spring 25, and the stop block 23 disengages from the locking ring groove, and the outer rotating cylinder 5 can rotate; releasing the button, under the action of the first spring 25, the stop block 23 rests against the locking ring groove again to achieve locking.

[0034] Furthermore, locking grooves 26 are evenly distributed along the circumference of the locking ring groove 24, and the stop block 23 is a sharp-tooth structure and can be inserted into the locking groove 26. When the stop block 23 is abutted against the locking ring groove under the action of the first spring 25, the sharp-toothed stop block 23 can be inserted into the locking groove 26; thereby further enhancing the locking effect, making it difficult for the outer rotating cylinder 5 to rotate relative to each other in the locked state, and improving the reliability of the telescope angle fixation.

[0035] The locking device has a simple structure and is easy to operate. The outer rotating cylinder 5 can be quickly locked and unlocked by pressing and releasing the button 21. The setting of the first spring 25 ensures the reliable engagement of the stop block 23 and the locking groove 26, improves the locking stability, and avoids the angular deviation of the telescope due to accidental touch during observation.

[0036] In the present invention, a handle 41 is connected and installed at one end of the outer rotating cylinder 5, and the handle 41 is located at an end close to the button 21; the setting of the handle 41 makes it convenient for the user to hold and operate the outer rotating cylinder 5, and is convenient for rotating and adjusting the outer rotating cylinder 5 after it is unlocked; because the handle 41 is close to the button, the user does not need to move his hand significantly when operating the button 21 to lock or unlock, thereby improving the consistency and convenience of the operation.

[0037] See also Figure 2-Figure 8 As shown, the fine-tuning device includes a rotating ring 51 that is coaxially rotatable in the outer rotating cylinder 5, and the rotating ring 51 is fixedly connected to the inner rotating column 6 by a connecting rod 50. An incomplete gear ring 52 is provided on the lower side of the inner wall of the rotating ring 51, and the upper side of the inner wall of the rotating ring 51 is a brake inner wall 53. A second rubber pad is provided on the brake inner wall 53. A movable seat 54 is movable up and down at the upper end of the handle 41, and an adjusting knob 55 is rotatably installed on the upper end of the movable seat 54. A transmission gear 56 and a driving gear 57 are coaxially rotatably installed on the lower end of the movable seat 54. The wheel 57 is engaged with the incomplete ring gear 52, and a driving gear 58 is provided on the rotating shaft of the adjusting knob 55. A reduction gear set 59 is engaged with the transmission gear 56 and the driving gear 58 on the movable seat 54. A brake block 510 is also provided on one side of the movable seat 54. An elastic component is also provided in the handle 41. The elastic component is connected to the movable seat 54 to keep the movable seat 54 in an upward shape. When the movable seat 54 remains in an upward shape, the driving gear 57 is disengaged from the incomplete ring gear 52 and the brake block 510 abuts against the brake inner wall 53.

[0038] The specific working principle of the fine-tuning device is as follows: during the adjustment operation, the adjusting knob 55 is pressed down by the finger. At this time, the driving gear 57 is engaged with the incomplete ring gear 52, and then the adjusting knob 55 is turned by the finger. The adjusting knob 55 drives the active gear 58 to rotate, and the active gear 58 is engaged with the reduction gear set 59. The reduction gear set 59 is then engaged with the transmission gear 56, thereby driving the driving gear 57 to rotate. At this time, the driving gear 57 is engaged with the incomplete ring gear 52, so that the rotating ring 51 rotates, realizing the rotation of the inner rotating column 6, and realizing the angle adjustment of the second connecting seat 8 and the main mirror body 1. Due to the setting of the reduction gear set, the adjustment accuracy is further improved, and high-precision fine-tuning operation is achieved.

[0039] When the adjustment is completed, loosen the adjustment knob 55. Under the action of the elastic component, the movable seat 54 drives the gear as a whole upward, so that the driving gear 57 is disengaged from the incomplete gear ring 52. At the same time, the brake block 510 rests on the brake inner wall 53, ensuring the stability of the inner rotating column 6. This structure is accurate and convenient to operate, and can meet the needs of fine adjustment of the observation angle.

[0040] The second rubber pad increases the friction between the brake block 510 and the brake inner wall 53. When the movable seat 54 is upward, it can better brake the rotating ring 51 to prevent it from rotating, further ensuring the stability of the inner rotating column 6 and the main mirror body 1.

[0041] Furthermore, the elastic component includes a guide plate 61 provided on the front and rear sides of the movable seat 54, and a downwardly extending guide rod 62 is provided on the upper side of the inner wall of the handle 41. The guide plate 61 moves up and down on the guide rod 62, and a limiting plate 63 is provided at the lower end of the guide rod 62. A second spring 64 is provided on the guide rod 62, and one end of the second spring 64 abuts against the limiting plate 63, and the other end abuts against the guide plate 61.

[0042] The guide rod 62 guides the up and down movement of the movable seat 54, ensuring the stability of the movement of the movable seat 54; the second spring 64 provides an upward elastic force for the movable seat 54, so that the movable seat 54 maintains an upward shape in a natural state, ensuring that the fine-tuning device is stable when not in use, with a simple structure and high reliability.

[0043] Furthermore, a portion of the adjusting knob 55 extends outside the handle 41 , and protective convex patterns are provided on the outer wall of the adjusting knob 55 .

[0044] Thus, the adjustment knob 55 partially extends out of the handle 41, making it convenient for the user to press and turn the knob 55 for fine-tuning operations; the protective convex pattern increases the friction between the fingers and the knob, avoiding slipping during operation, ensuring the accuracy of the fine-tuning operation, and also playing a certain protective role.

[0045] A stop column 81 is coaxially arranged on one side of the driving gear 57, and a limiting arc block 82 is arranged in the handle 41. A first rubber pad is arranged on the lower side of the limiting arc block 82. When the movable seat 54 remains in an upward shape, the stop column 81 abuts against the first rubber pad.

[0046] The stop column 81 cooperates with the first rubber pad on the limiting arc block 82. When the movable seat 54 is upward and the fine-tuning device is not working, it can further stop the driving gear 57 to prevent the driving gear 57 from rotating at will, thereby avoiding accidental rotation of the inner rotating column 6 and ensuring the stability of the telescope angle.

[0047] It is worth mentioning that the handle 41, button 21 and adjustment knob 55 are designed together to achieve one-handed operation. During operation, the handle 41 is held with one hand, and the fingers (index finger or middle finger) naturally extend to the button 21, while the thumb is naturally placed on the adjustment knob 55. Without the need for cooperation of both hands or large movements of the hands, core operations such as locking / unlocking the outer rotating cylinder 5 and fine-tuning the main lens body 1 can be completed. The entire process can be completed smoothly in a one-handed holding posture, greatly shortening the operation time.
