Technical Field
[0001] This utility model relates to the field of microscope technology, and more specifically, to a simple image-rotating structure. Background Technology
[0002] In the field of microscopy, the image rotation mechanism is a key component for adjusting the observation angle and direction of a microscope. Currently, most commercially available microscope image rotation mechanisms use belt connections for transmission. However, this transmission structure has many drawbacks in practical use.
[0003] As a transmission medium, the material and manufacturing process of belts determine their limited lifespan. After prolonged use, belts are prone to failure due to wear and aging, causing the image rotation mechanism to malfunction. This not only affects the stability and accuracy of the microscope but also increases the user's maintenance costs and time. Furthermore, belt drives are also prone to slippage under heavy loads or during long-term use, further impacting the accuracy and stability of the microscope's image rotation. Utility Model Content
[0004] The purpose of this utility model is to provide a simple image-shifting structure to solve the problem mentioned in the background art that the material and manufacturing process of belts as transmission media determine their limited service life.
[0005] To achieve the above objectives, this utility model provides a simple image-rotating structure, including an outer lens barrel, an adjusting ring installed at one end of the outer lens barrel, and an inner lens barrel connected to the other end of the outer lens barrel. An image-rotating prism is provided on the inner side of the adjusting ring, an outer toothed ring is fixed to the inner wall of the adjusting ring, and an inner toothed ring is fixed to the outer wall of the image-rotating prism. The teeth of the outer toothed ring face inward, and the teeth of the inner toothed ring face outward. An intermediate gear is provided between the inner and outer toothed rings, with one side of the intermediate gear meshing with the outer toothed ring and the other side of the intermediate gear meshing with the inner toothed ring.
[0006] Preferably, a pin hole is provided on the side of the outer lens barrel near the intermediate gear, a pin is fixedly installed in the pin hole, and the axis of the intermediate gear is rotatably connected to the pin.
[0007] Preferably, a protective cover is provided on the outer side of the adjustment ring. The protective cover has a ring structure and is connected and fixed to the outer lens barrel by a first locking bolt.
[0008] Preferably, the outer endoscope tube has a channel in the middle, and a sleeve is installed at one end of the inner endoscope tube. The sleeve is inserted into the channel, and the image-rotating prism is disposed inside the sleeve.
[0009] Preferably, an annular plate is installed on the outer wall of the sleeve, and the annular plate is connected and fixed to the outer lens barrel by a second locking bolt.
[0010] Preferably, the outer wall of the adjustment ring is provided with anti-slip texture.
[0011] Preferably, the outer wall of the outer lens tube is provided with an annular groove near the adjustment ring, and the adjustment ring is fitted into the annular groove.
[0012] Preferably, the internal toothed ring is fitted around the outside of the rotating prism and is fixed by bolts.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In this simplified image-rotating structure, the use of gear transmission (external gear ring, intermediate gear, internal gear ring) instead of traditional belt transmission significantly improves the stability and accuracy of the structure. Gear transmission features accurate transmission ratio and high transmission efficiency, effectively avoiding slippage that may occur in belt transmission, ensuring more accurate and reliable adjustment of the microscope's observation angle and direction.
[0015] Gear transmission components (such as external gear rings, intermediate gears, and internal gear rings) typically have a longer service life and are more wear-resistant and aging-resistant than belt drives. Therefore, this image-spinning structure can maintain stable performance for extended periods, reducing the frequency of repairs and replacements due to damage to transmission components, thus lowering maintenance costs and time for users. The design of this image-spinning structure is relatively simple, with clear connections and transmission methods between components, facilitating assembly and disassembly. For example, the adjusting ring is connected and fixed to the outer lens barrel via a protective cover and the first locking bolt, while the sleeve is connected and fixed to the outer lens barrel via an annular plate and the second locking bolt. These design features make the assembly and maintenance of the entire image-spinning structure more convenient and faster.
[0016] The image-rotating prism, a key optical element in the microscope, is cleverly installed within a sleeve, and image rotation is achieved through the transmission of an internal gear ring, an external gear ring, and an intermediate gear. This design not only protects the image-rotating prism from interference and damage from the external environment but also ensures its stability and accuracy during the image rotation process.

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.
[0024] This utility model provides a simple image rotation structure, such as Figures 1-3 As shown, the system includes an outer lens tube 1, an adjusting ring 2 mounted at one end of the outer lens tube 1, and an inner lens tube 3 connected to the other end of the outer lens tube 1. An image-rotating prism 4 is disposed inside the adjusting ring 2. An outer toothed ring 21 is fixed to the inner wall of the adjusting ring 2, and an inner toothed ring 41 is fixed to the outer wall of the image-rotating prism 4. The teeth of the outer toothed ring 21 face inwards, and the teeth of the inner toothed ring 41 face outwards. An intermediate gear 5 is disposed between the inner toothed ring 41 and the outer toothed ring 21. One side of the intermediate gear 5 meshes with the outer toothed ring 21, and the other side of the intermediate gear 5 meshes with the inner toothed ring 41. By mounting the adjusting ring 2 at one end of the outer lens tube 1 and connecting the inner lens tube 3 to the other end of the outer lens tube 1, the basic framework of the image-rotating structure is formed. The image-rotating prism 4 disposed inside the adjusting ring 2 realizes the image-rotating function of the optical path. Specifically, an external gear ring 21 is fixed to the inner wall of the adjusting ring 2, and an internal gear ring 41 is fixed to the outer wall of the rotating prism 4. The teeth of the external gear ring 21 face inward, and the teeth of the internal gear ring 41 face outward. This gear arrangement cleverly utilizes the spatial structure. An intermediate gear 5 is arranged between the internal gear ring 41 and the external gear ring 21, with one side of the intermediate gear 5 meshing with the external gear ring 21 and the other side meshing with the internal gear ring 41, forming a stable gear transmission mechanism. This structural design not only achieves precise image rotation adjustment of the rotating prism 4 but also ensures stability and reliability during the image rotation process, improving the practicality and durability of the entire image rotation structure.
[0025] In this embodiment, a pin hole 12 is provided on the side of the outer lens barrel 1 near the intermediate gear 5. A pin is fixedly installed in the pin hole 12, and the axis of the intermediate gear 5 is rotatably connected to the pin. Through the rotatable connection between the pin and the intermediate gear 5, the intermediate gear 5 is stably installed and can rotate flexibly on the outer lens barrel 1. This structural design ensures the smoothness of gear transmission, making the image rotation adjustment of the image rotating prism 4 more flexible and reliable.
[0026] Specifically, a protective cover 22 is provided on the outer side of the adjusting ring 2. The protective cover 22 has a ring structure and is connected and fixed to the outer lens barrel 1 by a first locking bolt 221. The design of the protective cover 22 effectively protects the adjusting ring 2 and its internal gear transmission mechanism from interference and damage from the external environment. The connection and fixation of the protective cover 22 to the outer lens barrel 1 by the first locking bolt 221 ensures the stability and reliability of the protective cover 22 and improves the durability of the entire image rotation structure.
[0027] Furthermore, a channel 11 is provided in the middle of the outer endoscope tube 1, and a sleeve 31 is installed at one end of the inner endoscope tube 3. The sleeve 31 is inserted into the channel 11, and the image-rotating prism 4 is placed inside the sleeve 31. Through the insertion and engagement of the channel 11 and the sleeve 31, a stable connection between the inner endoscope tube 3 and the outer endoscope tube 1 is achieved, while providing installation space for the image-rotating prism 4. This structural design makes the assembly of the image-rotating structure more convenient and quick, and also ensures the stability and accuracy of the image-rotating prism 4 during the image-rotation process.
[0028] Furthermore, an annular plate 32 is installed on the outer wall of the sleeve 31, and the annular plate 32 is connected and fixed to the outer lens barrel 1 by a second locking bolt 33. The design of the annular plate 32 and the second locking bolt 33 further enhances the connection stability between the sleeve 31 and the outer lens barrel 1. Through the tightening action of the second locking bolt 33, it is ensured that the sleeve 31 will not loosen or fall off during the image rotation process, thereby improving the reliability and safety of the entire image rotation structure.
[0029] Furthermore, the outer wall of the adjustment ring 2 is provided with anti-slip texture. This anti-slip texture design increases user comfort during use, making the rotation of the adjustment ring 2 smoother and less prone to slipping. This detailed design improves the user experience and also makes the adjustment of the rotating structure more precise and reliable.
[0030] Furthermore, an annular groove is provided on the outer wall of the outer lens barrel 1 near the adjusting ring 2, and the adjusting ring 2 is fitted into the annular groove. The design of the annular groove provides a stable installation position for the adjusting ring 2 or its related fixing components. Through the cooperation of the annular groove, the stability and accuracy of the adjusting ring 2 during the image rotation process are ensured, and the assembly convenience of the entire image rotation structure is also improved.
[0031] Furthermore, the internal gear ring 41 is fitted onto the outside of the rotating prism 4 and fixed by bolts. The internal gear ring 41 is fixed to the outside of the rotating prism 4 by bolts, achieving a stable connection between the internal gear ring 41 and the rotating prism 4. This structural design ensures the smoothness and accuracy of gear transmission, and also enables the rotating prism 4 to maintain stable performance and optical effects during image rotation.
[0032] In use, the simple image-rotating structure of this utility model firstly uses the outer lens tube 1 as the main body of the entire image-rotating structure. One end of the outer lens tube 1 is equipped with an adjustment ring 2, and the other end is connected to the inner lens tube 3, which constitutes the basic framework of the image-rotating structure.
[0033] An image-rotating prism 4 is installed on the inner side of the adjustment ring 2 to achieve the image-rotating function of the optical path. When it is necessary to adjust the observation angle, rotating the adjustment ring 2 will drive the image-rotating prism 4 to rotate, thereby changing the direction of the optical path. An outer toothed ring 21 is fixed to the inner wall of the adjustment ring 2, and an inner toothed ring 41 is fixed to the outer wall of the image-rotating prism 4, with the teeth of the outer toothed ring 21 facing inward and the teeth of the inner toothed ring 41 facing outward. An intermediate gear 5 is arranged between the inner toothed ring 41 and the outer toothed ring 21. One side of the intermediate gear 5 meshes with the outer toothed ring 21, and the other side meshes with the inner toothed ring 41, forming a stable gear transmission mechanism. When the adjustment ring 2 is rotated, the outer toothed ring 21 drives the intermediate gear 5 to rotate, and the intermediate gear 5 then drives the inner toothed ring 41 to rotate, thereby achieving precise image-rotating adjustment of the image-rotating prism 4.
[0034] A pin hole 12 is provided on the side of the outer lens barrel 1 near the intermediate gear 5. A pin is fixedly installed in the pin hole 12, and the shaft of the intermediate gear 5 is rotatably connected to the pin.

The protective cover 22 has a ring structure and is connected and fixed to the outer lens barrel 1 by the first locking bolt 221. The protective cover 22 effectively protects the adjusting ring 2 and its internal gear transmission mechanism from interference and damage from the external environment.
[0036] A channel 11 is provided in the middle of the outer tube 1, and a sleeve 31 is installed at one end of the inner tube 3. The sleeve 31 is inserted into the channel 11.

[0037] An annular plate 32 is installed on the outer wall of the sleeve 31, and the annular plate 32 is connected and fixed to the outer lens barrel 1 by a second locking bolt 33. This design further enhances the connection stability between the sleeve 31 and the outer lens barrel 1, ensuring that the sleeve 31 will not loosen or fall off during image rotation.
[0038] The outer wall of the adjustment ring 2 is textured with anti-slip material. This detail enhances user comfort during use, making the rotation of the adjustment ring 2 smoother and less prone to slipping.
[0039] An annular groove is provided on the outer wall of the outer lens barrel 1 near the adjusting ring 2, and the adjusting ring 2 is fitted into the annular groove. This design provides a stable mounting position for the adjusting ring 2 or its related fixing components, ensuring the stability and accuracy of the adjusting ring 2 during image rotation.
