Description

Technical Field

[0001] This utility model relates to a limiting structure, specifically a limiting structure for a lens barrel and a lens mount, belonging to the field of optical equipment technology. Background Technology

[0002] The microscope tube is a cylindrical structure mounted at the tip of the telescope arm, connecting the eyepiece at the top and the objective lens turret at the bottom. Its function is to hold the eyepiece or imaging device, and the magnification can be adjusted by changing the distance between the two lenses, since imaging only occurs at a specific distance. The lens mount is a crucial component of optical equipment; it typically supports and secures the microscope tube, ensuring its stability and accuracy during use. The design and structure of the lens mount directly impact the performance of the optical equipment, especially in applications requiring high precision and stability, such as telescopes and microscopes. In optical equipment, the positioning structure between the microscope tube and the lens mount is extremely important, ensuring the correct position and stability of the microscope tube within the mount.

[0003] Currently, the structural design of lens barrels and mounts may involve the installation, positioning, and functional requirements of multiple components. Due to the involvement of multiple parts, the manufacturing tolerances of each part accumulate during assembly. When there are many dimensional constraints, this tolerance accumulation may cause the dimensions of some critical parts to exceed the expected range, further exacerbating the dimensional tension problem. Due to the large number of dimensional constraints, problems of dimensional compression tension and sealing issues when using screws for limiting are prone to occur. To address these issues, we provide a limiting structure for lens barrels and mounts to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a limiting structure for the lens barrel and lens mount, thereby resolving the issues. The specific technical solution is as follows:

[0005] A limiting structure for lens barrel and lens mount includes a handwheel, a lens barrel body, and a lens mount body. The outer side of the lens barrel body is provided with threads, and the inner wall of the lens mount body is provided with a threaded ring, which is connected to the threads. A retaining ring is provided inside the lens mount body, and a sealing ring is movably provided at the top of the retaining ring, which is located inside the lens mount body. A baffle is provided at the top of the sealing ring, which is located inside the lens mount body.

[0006] Preferably, a protrusion is provided on the outer side of the handwheel, and the handwheel is located on the outer side of the lens barrel body.

[0007] Preferably, the lens barrel body is movably disposed inside the lens base body, one end of the lens barrel body is in contact with the inner wall of the lens base body, and a connecting block is provided on the inner side of the lens base body.

[0008] Preferably, a mounting groove is formed inside the mirror base body, and the retaining ring is movably disposed inside the mounting groove.

[0009] Preferably, the mirror base body has a storage groove inside, and the storage groove is located above the first mounting groove, and the sealing ring is located on one side of the storage groove.

[0010] Preferably, the mirror base body has a second mounting slot inside, and the second mounting slot is located above the storage slot, and the baffle is disposed inside the second mounting slot.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, by setting components such as a retaining ring, a sealing ring, and a baffle, during the process of assembling the lens barrel body into the lens mount body, the threads on the outer side of the lens barrel body rotate within the threaded ring opened on the inner wall of the lens mount body. A baffle is added to the threaded port of the lens mount body, and a sealing ring is added between the retaining ring and the baffle. When the lens mount body moves to the left relative to the lens barrel body, the lens mount body reaches the designed reserved position. At this time, the baffle presses against the threaded port of the lens barrel body, and the movement of the lens barrel body and the lens mount body is limited. The retaining ring achieves a sealing effect by compressing the sealing ring radially through thread engagement with the lens mount body.

[0013] 2. In this utility model, by providing components such as a first mounting groove, a storage groove, and a second mounting groove, the first mounting groove and the second mounting groove provide installation space for the retaining ring and the retaining plate, respectively. When the threaded port of the mirror base body is pressed against the threaded retaining plate, the retaining plate and the retaining ring can compress and deform the sealing ring. The compressed and deformed sealing ring can fill the storage groove, and the deformation of the sealing ring can fill and seal the gap between the mirror barrel and the mirror base.

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A limiting structure for the lens barrel and lens mount;

[0023] The device includes a handwheel 1, a lens barrel body 3, and a lens base body 5. The outer side of the lens barrel body 3 is provided with threads 4. The inner wall of the lens base body 5 is provided with a threaded ring 6, and the threaded ring 6 is threadedly connected to the threads 4. The inside of the lens base body 5 is provided with a retaining ring 10. A sealing ring 11 is movably provided at the top of the retaining ring 10 and is located inside the lens base body 5. A baffle 12 is provided at the top of the sealing ring 11 and is located inside the lens base body 5.

[0024] The lens barrel body 3 is movably disposed inside the lens base body 5. During the assembly of the lens barrel body 3 into the lens base body 5, the threads 4 on the outer side of the lens barrel body 3 rotate within the threaded ring 6 opened on the inner wall of the lens base body 5. A baffle 12 is added to the threaded port of the lens base body 5, and a sealing ring 11 is added between the baffle 12 and the retaining ring 10. When the lens base body 5 moves to the left relative to the lens barrel body 3, the lens base body 5 reaches the designed reserved position. At this time, the baffle 12 presses against the threaded port of the lens barrel body 3, and the movement of the lens barrel body 3 and the lens base body 5 is limited. The retaining ring 10 achieves a sealing effect by compressing the sealing ring 11 radially through thread engagement with the lens base body 5.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A limiting structure for the lens barrel and lens mount;

[0026] A protrusion 2 is provided on the outer side of the handwheel 1. The handwheel 1 is located on the outer side of the lens barrel body 3. The lens barrel body 3 is movably located inside the lens base body 5. One end of the lens barrel body 3 contacts the inner wall of the lens base body 5. A connecting block 13 is provided on the inner side of the lens base body 5. A first mounting groove 7 is opened inside the lens base body 5. A retaining ring 10 is movably located inside the first mounting groove 7. A storage groove 8 is opened inside the lens base body 5, and the storage groove 8 is located above the first mounting groove 7. A sealing ring 11 is located on one side of the storage groove 8. A second mounting groove 9 is opened inside the lens base body 5, and the second mounting groove 9 is located above the storage groove 8. A baffle 12 is located inside the second mounting groove 9.

[0027] In optical equipment, the handwheel 1 is used to adjust the focal length or other parameters. For example, the coarse and fine adjustment knobs on a microscope are types of handwheel 1. They can adjust the distance between the objective lens and the sample to find a clear image. The coarse adjustment knob can quickly move the microscope tube, while the fine adjustment knob is used to fine-tune the image sharpness. The protrusion 2 on the outside of the handwheel 1 increases the coefficient of friction between the handwheel 1 and the user. The microscope tube body 3 is an important component of the optical equipment, usually located at the front upper part of the microscope arm. The eyepiece is mounted at the upper end, and the objective lens turret is mounted at the lower end. The function of the microscope tube is to connect the eyepiece and the objective lens, allowing light to pass through and be focused on the sample. In some microscopes, the length of the microscope tube is fixed. For example, the international standard length of microscope tubes is set at 160mm. This figure is usually marked on the objective lens housing. The microscope mount body 5 is the optical... The base of the microscope supports the entire microscope body. It is usually a stable structure that provides sufficient support to ensure that the microscope does not wobble during use. The base may also be equipped with components such as a reflector or a light source for illumination. The connecting block 13 on the inner side of the base body 5 facilitates the positioning of components, such as screws, to position and install the base body 5. The first mounting slot 7, the storage slot 8, and the second mounting slot 9 are opened sequentially from bottom to top inside the base body 5. The first mounting slot 7 and the second mounting slot 9 provide installation space for the retaining ring 10 and the retaining plate 12, respectively. When the threaded port of the base body 5 is pressed against the threaded retaining plate 12, the retaining plate 12 and the retaining ring 10 can compress and deform the sealing ring 11. After compression and deformation, the sealing ring 11 can fill the storage slot 8 to achieve a sealing effect.

[0028] In use, during the assembly of the lens barrel body 3 into the lens base body 5, the threads 4 on the outer side of the lens barrel body 3 rotate within the threaded ring 6 on the inner wall of the lens base body 5. A baffle 12 is added to the threaded port of the lens base body 5, and a sealing ring 11 is added between the baffle 12 and the retaining ring 10. When the lens base body 5 moves to the left relative to the lens barrel body 3, the lens base body 5 reaches the designed reserved position. At this time, the baffle 12 presses against the threaded port of the lens barrel body 3, and the movement of the lens barrel body 3 and the lens base body 5 is limited. The retaining ring 10 achieves a sealing effect by compressing the sealing ring 11 radially through threaded engagement with the lens base body 5.
