Description

TECHNICAL FIELD

[0001] The present application relates to the field of telescope technology, in particular to a full-plastic large-aperture wide-angle telescope. BACKGROUND

[0002] In the field of telescopes, large-aperture wide-angle telescopes are favored in astronomical observation, long-distance observation, and other scenarios because they can collect more light and provide a wider field of view. However, in practical applications, the connection structure of the tripod and the main mirror body of traditional large-aperture wide-angle telescopes directly affects the convenience and accuracy of observation operations. Currently, most telescopes on the market use a simple shaft connection method, i.e., the main mirror body is connected to the connecting seat of the tripod through a single shaft to achieve rough adjustment of the up-down 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 adjustment device, the observer cannot make fine adjustments to the angle of the main mirror body after completing the initial angle adjustment. For example, when observing a distant stationary target (such as the details of an ancient building or the landscape), the initial adjustment may bring the target into the field of view, but it is difficult to accurately aim it at the center of the field of view. This lack of adjustment accuracy often prevents the telescope from achieving the ideal observation state, greatly affecting the observation experience and the accuracy of data recording. SUMMARY

[0028] The following detailed description provides various different embodiments or examples of the application. Of course, these are merely examples and are not intended to be limiting. Additionally, like reference numerals and characters can be used to denote like elements throughout the different illustrative embodiments. These repeated use of reference characters does not connote that a particular feature is of particular importance or is used across multiple industry or technical or legal fields. Also, different numbering and / or characters can be used to denote different embodiments.

[0029] As shown in Figures 1-9 A full-plastic large-aperture wide-angle telescope includes a main mirror body 1, a tripod 2, and a connecting assembly connecting the main mirror body 1 and the tripod 2. The connecting assembly includes a first connecting seat 3 arranged on the tripod 2, a cylindrical sleeve 4 arranged on the first connecting seat 3, an outer rotating cylinder 5 rotatably arranged in the cylindrical sleeve 4, an inner rotating column 6 coaxially rotatably arranged in the outer rotating cylinder 5, an avoiding groove 7 arranged on the outer wall of the outer rotating cylinder 5, and a second connecting seat 8 arranged on the main mirror body 1. One end of the second connecting seat 8 is arranged in the avoiding groove 7 and is fixedly connected with the inner rotating column 6. A locking device and a fine adjustment device are arranged on the outer rotating cylinder 5. The locking device is used for locking the outer rotating cylinder 5 on the cylindrical sleeve 4. The fine adjustment device is used for driving the inner rotating column 6 to rotate in the outer rotating cylinder 5.

[0030] According to the above structure, first, the outer rotating cylinder 5 is rotated in the cylindrical sleeve 4, so that the up-down angle of the main mirror body 1 can be coarsely adjusted. Then, the fine adjustment device is operated to drive the inner rotating column 6 to rotate in the outer rotating cylinder 5, so that the observation angle of the telescope can be finely adjusted. When an observer is observing, the observer can accurately adjust the direction of the telescope by the fine adjustment device, so that the target can be clearly presented in the field of view, and any subtle observation details can not be missed. The accuracy of observation is significantly improved, and the telescope is especially suitable for astronomical observation and long-distance target detail observation which have very high observation accuracy requirements.

[0031] In addition, 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, the locking device is used for fixing, so that the stability of the telescope during observation can be ensured, and the angle deviation caused by external interference or accidental touch can be avoided, so that the stability and continuity of the observation process are ensured, and a powerful guarantee for obtaining high-quality observation results is provided.

[0032] The all-plastic large-aperture wide-angle telescope of the present invention also includes an objective lens 10 disposed at the front end of the main body 1, a focusing tube 11 that slides back and forth at the rear end of the main body 1, an eyepiece 12 disposed on the focusing tube 11, and a finder scope 13 disposed on the main body 1.

[0033] The main body 1, objective lens 10, focusing tube 11, and eyepiece 12 mentioned above are all made of plastic. Compared with traditional metal telescopes, the weight is significantly reduced, making them easier to carry outdoors and operate by hand for extended periods. They are especially suitable for outdoor adventures, sightseeing, and other similar scenarios. In addition, plastic has good corrosion resistance and impact resistance, and can adapt to complex environments such as humid, dusty, and temperature-differential environments. This reduces damage to the equipment caused by rust or impacts, extends its service life, and lowers maintenance costs.

[0034] See Figure 3 , Figure 9 As shown, the locking device includes a button 21 located on the front side of the outer rotating cylinder 5, a fixing block 22 connected to one side of the button 21 and inside the outer rotating cylinder 5, a stop block 23 movably extending out of the outer rotating cylinder 5 on the front side of the fixing block 22, a locking ring groove provided on the inner wall of the cylindrical sleeve 4, and a first spring 25 provided at the inner end of the button 21. The stop block 23 abuts against the locking ring groove under the action of the first spring 25.

[0035] Specifically, the button 21 of the locking device is installed on the front side of the outer rotating cylinder 5, and the fixing block 22 on one side of the button 21 is located inside the outer rotating cylinder 5. The front side of the fixing block 22 extends out of the outer rotating cylinder 5 and is connected to the stop block 23. The inner wall of the cylindrical sleeve 4 is provided with a locking ring groove. The first spring 25 at the inner end of the button 21 causes the stop block 23 to abut 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, allowing the outer rotating cylinder 5 to rotate. Releasing the button causes the stop block 23 to abut against the locking ring groove again under the action of the first spring 25, thus achieving locking.

[0036] Furthermore, the locking ring groove 24 has locking grooves 26 evenly distributed along its circumference. The stop block 23 has a pointed tooth structure and can be inserted into the locking groove 26. When the stop block 23 abuts against the locking ring groove under the action of the first spring 25, the pointed tooth-shaped stop block 23 can be inserted into the locking groove 26. This further enhances the locking effect, making it less likely for the outer rotating cylinder 5 to rotate relative to the outside in the locked state, thus improving the reliability of the telescope angle fixation.

[0037] 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 stability of the lock, and avoids the telescope from shifting its angle due to accidental contact during observation.

[0038] In the present application, a handle 41 is installed at one end of the outer rotating cylinder 5, and the handle 41 is located at the end close to the button 21. The handle 41 is arranged to facilitate the user to hold and operate the outer rotating cylinder 5, and to facilitate the rotation adjustment of the outer rotating cylinder 5 after it is unlocked. Since the handle 41 is close to the button, the user's hand does not need to move greatly when operating the button 21 to lock or unlock, thereby improving the continuity and convenience of operation.

[0039] Referring to Figures 2-8 As shown, the fine adjustment device comprises a rotating ring 51 coaxially rotating in the outer rotating cylinder 5, the rotating ring 51 and the inner rotating column 6 are fixedly connected through a connecting rod 50, an incomplete gear ring 52 is arranged on the lower side of the inner wall of the rotating ring 51, the upper side of the inner wall of the rotating ring 51 is a brake inner wall 53, a second rubber pad is arranged on the brake inner wall 53, an activity seat 54 is movably arranged on the upper end of the handle 41, an adjustment knob 55 is rotatably installed on the upper end of the activity seat 54, a transmission gear 56 and a driving gear 57 are coaxially rotatably installed on the lower end of the activity seat 54, the driving gear 57 is engaged with the incomplete gear ring 52, a driving gear 58 is arranged on the rotating shaft of the adjustment knob 55, a speed reduction gear set 59 is transmissionally engaged between the transmission gear 56 and the driving gear 58 on the activity seat 54, a brake block 510 is further arranged on one side of the activity seat 54, and an elastic assembly is further arranged in the handle 41, the elastic assembly is connected with the activity seat 54, so that the activity seat 54 maintains an upward shape, and when the activity seat 54 maintains the upward shape, the driving gear 57 is disengaged from the incomplete gear ring 52, and the brake block 510 abuts against the brake inner wall 53.

[0040] The specific working principle of the fine adjustment device is as follows: during adjustment operation, the adjustment knob 55 is pressed down by the finger, at this time, the driving gear 57 is engaged with the incomplete gear ring 52, then the adjustment knob 55 is adjusted by the finger, the adjustment knob 55 drives the driving gear 58 to rotate, the driving gear 58 is engaged with the speed reduction gear set 59, the speed reduction gear set 59 is engaged with the transmission gear 56, and then the driving gear 57 is driven to rotate, at this time, the driving gear 57 is engaged with the incomplete gear ring 52, so that the rotating ring 51 rotates, the inner rotating column 6 rotates, and the angle adjustment of the second connecting seat 8 and the main mirror body 1 is realized. Since the speed reduction gear set is arranged, the adjustment accuracy is further improved, and high-precision fine adjustment operation is realized.

[0041] When the adjustment is completed, the adjustment knob 55 is loosened, and under the action of the elastic assembly, the movable seat 54 drives the gear as a whole upwards, so that the driving gear 57 is separated from the incomplete gear ring 52, and at the same time, the brake block 510 abuts against the brake inner wall 53, thereby ensuring the stability of the inner rotating column 6. The structure is accurate and convenient to operate, and can meet the fine adjustment requirement of the observation angle.

[0042] The second rubber pad increases the friction between the brake block 510 and the brake inner wall 53, and when the movable seat 54 moves upwards, the rotating ring 51 can be better braked to prevent it from rotating, thereby further ensuring the stability of the inner rotating column 6 and the main mirror body 1.

[0043] Further, the elastic assembly comprises guide plates 61 arranged on the front and rear sides of the movable seat 54, a guide rod 62 extending downwards is arranged on the inner wall of the handle 41, the guide plates 61 move up and down on the guide rod 62, a limiting plate 63 is arranged at the lower end of the guide rod 62, and a second spring 64 is arranged on the guide rod 62, one end of the second spring 64 abuts against the limiting plate 63, and the other end abuts against the guide plate 61.

[0044] The guide rod 62 plays a guiding role in the up and down movement of the movable seat 54, thereby 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 form in a natural state, thereby ensuring the stability of the fine adjustment device in a state of non-use, and the structure is simple and has high reliability.

[0045] Further, part of the adjustment knob 55 extends out of the handle 41, and a protective convex pattern is arranged on the outer wall of the adjustment knob 55.

[0046] Therefore, part of the adjustment knob 55 extends out of the handle 41, which facilitates the user to press and rotate the knob 55 to perform fine adjustment operation; the protective convex pattern increases the friction between the finger and the knob, thereby avoiding slipping during operation, ensuring the accuracy of the fine adjustment operation, and also playing a certain protective role.

[0047] A stop column 81 is coaxially arranged on one side of the driving gear 57, and a limiting arc-shaped block 82 is arranged in the handle 41, a first rubber pad is arranged on the lower side of the limiting arc-shaped block 82, and when the movable seat 54 maintains an upward form, the stop column 81 abuts against the first rubber pad.

[0048] The stop column 81 cooperates with the first rubber pad on the limiting arc-shaped block 82, and when the movable seat 54 moves upwards and the fine adjustment device does not work, the stop column 81 can further stop the driving gear 57, thereby preventing the driving gear 57 from rotating at will, avoiding the accidental rotation of the inner rotating column 6, and ensuring the stability of the angle of the telescope.

[0049] It is worth mentioning that the handle 41, the button 21 and the adjusting knob 55 are designed together, and single-hand operation can be realized. When operating, the handle 41 is held by one hand, the fingers (index finger or middle finger) naturally extend to the button 21, and the thumb naturally rests on the adjusting knob 55. Without the cooperation of both hands or the large movement of the hand, the core operations such as the locking / unlocking of the outer rotating cylinder 5 and the fine adjustment of the main mirror body 1 can be completed. The whole process can be continuously completed in the single-hand holding posture, and the operation time is greatly shortened.

[0050] The person skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
