Description

Technical Field

[0001] This application relates to the field of microscope technology, and more specifically, to a protective structure and a microscope. Background Technology

[0002] A microscope is an instrument primarily used to magnify tiny objects that are visible to the naked eye. When in use, a microscope has a base and a lens. To prevent the lens from accumulating dust when not in use, it needs to be protected, requiring the use of a protective structure.

[0003] In response, Chinese patent application number CN202223335677.X discloses a protective structure for a microscope lens. This solution mainly involves pulling the protective cylinder when protection of the lens body is required, causing the protective cylinder to move downwards, which in turn causes the connecting rod to move downwards, thereby moving the mounting block and the baffle, which compresses the spring. When the protective cylinder moves to the lower side of the lens body, it is then turned so that it rotates around the connecting rod. When the protective cylinder is directly opposite the lens body, it is released, and under the action of the spring, the protective cylinder rebounds, allowing it to fit over the outer end of the lens body, thus protecting the lens body.

[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] The protective cylinder needs to be operated multiple times during protection, which is cumbersome. Utility Model Content

[0006] To overcome the above deficiencies, this application provides a protective structure and microscope, which aim to improve the problems mentioned in the background art.

[0007] In a first aspect, embodiments of this application provide a protective structure, including a lens cover, wherein a tapered hole is provided on the lens cover and the tapered hole abuts against the end face of the lens, and an elastic hinge seat is connected to the lens cover, wherein an elliptical spring ring is connected to the hinge seat and the spring ring is clamped on the outer circle of the lens.

[0008] In one specific implementation, the inner wall of the conical hole inside the lens cover is fitted with a soft pad.

[0009] In the above process, the soft pad can easily fit the outer edge of the lens tip, achieving a better fit and thus a seal.

[0010] In one specific embodiment, the hinge seat includes a mounting ring that is fixedly connected to the end face of the lens cover.

[0011] In the above implementation process, the mounting ring is used to fix the hinge seat, and the large area of ​​the mounting ring allows for a more stable fixed connection with the end face of the lens cover.

[0012] In one specific implementation, spring pieces are fixedly connected to both ends of the mounting ring, a rotating shaft is fixedly connected to the upper end of the spring pieces, a connecting plate is rotatably connected to the rotating shaft, and the connecting plate is fixedly connected to both ends of the spring ring.

[0013] In the above process, the spring sheet and the mounting ring are integrally formed. When the spring sheet deforms inward, the deformation of the spring ring is achieved through the hinge of the rotating shaft and the connecting plate.

[0014] In one specific implementation, the two ends of the long shaft of the spring ring are provided with welding planes that are adapted to the connecting plate.

[0015] In the above implementation process, the planes at both ends of the long axis of the spring are spot-welded to the connecting plate.

[0016] In one specific implementation, rubber pads are fixedly connected to both ends of the short shaft of the spring coil.

[0017] In the above process, the rubber pad is used to increase static friction, making it easier to clamp stably on the outer circle of the lens. The rubber pad can also protect the outer circle of the lens from scratches.

[0018] In one specific implementation, a desiccant is provided inside the lens cover.

[0019] In the above implementation process, when the lens cover is placed on the lens, the desiccant absorbs the moisture between the lens and the lens cover, thereby better protecting the lens on the lens. In this embodiment, the bottom end of the conical hole of the lens cover is provided with a groove for accommodating desiccant particles. A breathable film is pasted at the opening of the groove to seal the desiccant particles inside. After a long time, the breathable film can be peeled off, the desiccant can be replaced, and a new breathable film can be pasted on.

[0020] Secondly, this application also provides a microscope including the aforementioned protective structure.

[0021] Compared with the prior art, the beneficial effects of this application are: the conical hole on the lens cover abuts against the lens cross-section to form a seal, and the spring ring clamps the outer circle of the lens to form a fixation. The conical hole is easy to adapt to various lens shapes and specifications, and the spring ring can also adapt to various lens diameters. The overall structure is simple and easy to operate.

[0028] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0029] Please see Figures 1-4 This application provides a protective structure, including a lens cover 10. The lens cover 10 has a tapered hole that abuts against the end face of a lens. A flexible hinge seat 20 is connected to the lens cover 10, and an elliptical spring ring 30 is connected to the hinge seat 20. The spring ring 30 is clamped onto the outer circumference of the lens. The tapered hole on the lens cover 10 forms a seal against the lens cross-section, and the spring ring 30 clamps onto the outer circumference of the lens for fixation. The tapered hole is easily adaptable to various lens shapes and specifications, and the spring ring 30 can also adapt to various lens diameters. The overall structure is simple and easy to operate.

[0030] Please see Figures 1-4 A soft pad 40 is fitted to the inner wall of the conical hole inside the lens cover 10. The soft pad 40 facilitates a better fit to the outer edge of the lens tip, thereby achieving a seal.

[0031] Please see Figures 1-4 The hinge base 20 includes a mounting ring 21, which is fixedly connected to the end face of the lens cover 10. The mounting ring 21 is used to fix the hinge base 20. The large area of ​​the mounting ring 21 allows for a more stable fixed connection with the end face of the lens cover 10. In specific implementations, since the lens cover 10 is made of plastic, a buckle can be provided on the end face of the lens cover 10 to directly fasten the mounting ring 21 to the end face of the lens cover 10 for easy assembly.

[0032] Please see Figures 1-4The mounting ring 21 has spring pieces 22 fixedly connected to both ends, and a rotating shaft 23 is fixedly connected to the upper end of the spring pieces 22. A connecting plate 24 is rotatably connected to the rotating shaft 23, and the connecting plate 24 is fixedly connected to both ends of the spring ring 30. The spring pieces 22 and the mounting ring 21 are integrally formed of metal. When the spring pieces 22 deform inward, the deformation of the spring ring 30 is achieved through the hinge of the rotating shaft 23 and the connecting plate 24.

[0033] Please see Figures 1-4 The long shaft of the spring ring 30 has flat surfaces at both ends for welding, which are adapted to the connecting plate 24. Both the spring ring 30 and the connecting plate 24 are made of metal, and the flat surfaces at both ends of the long shaft of the spring ring 30 are spot welded to the connecting plate 24.

[0034] Please see Figures 1-4 Rubber pads 50 are fixedly connected to both ends of the short shaft of the spring ring 30. Rubber pads 50 are used to increase static friction, making it easier to clamp stably on the outer circle of the lens. Rubber pads 50 can also protect the outer circle of the lens from scratches.

[0035] Please see Figures 1-4 The lens cover 10 contains a desiccant 60. When the lens cover 10 is placed on the lens, the desiccant 60 absorbs moisture between the lens and the lens cover 10, thereby better protecting the lens elements. In this embodiment, the bottom of the conical hole of the lens cover 10 has a groove for accommodating the desiccant 60 particles. A breathable membrane is attached to the opening of the groove to seal the desiccant 60 particles inside. After a long period of time, the breathable membrane can be removed, the desiccant 60 replaced, and a new breathable membrane attached.

[0036] Please see Figures 1-4 This application also provides a microscope including the aforementioned protective structure.

[0037] The working principle of this protective structure is as follows: Pinching the two spring clips 22 with your fingers causes them to retract inwards, shortening the major axis and lengthening the minor axis of the elliptical spring ring 30, forming a circle that fits over the outer circumference of the lens until the lens end face presses firmly against the soft pad 40, creating a seal. The desiccant 60 is used to keep the sealed area dry, thus better protecting the lens elements. Then, releasing your fingers allows the spring clips 22 and spring ring 30 to return to their original clamped position on the outer circumference of the lens, completing the fixation. In summary, the conical hole on the lens cover 10 forms a seal against the lens cross-section, and the spring ring 30 clamps the outer circumference of the lens for fixation. The conical hole easily adapts to various lens shapes and specifications, and the spring ring 30 can also adapt to various lens diameters. The overall structure is simple and easy to operate.
