Technical Field
[0001] This application relates to the field of microscope technology, and more specifically, to a microscope illumination device. Background Technology
[0002] A microscope is an optical instrument consisting of one or more convex lenses, and it marks humanity's entry into the atomic age. It is primarily used to magnify tiny objects so they can be seen with the naked eye. Microscope illumination equipment is used when operating a microscope.
[0003] In response, Chinese patent application number CN202021587860.7 discloses a microscope LED illumination source. This solution mainly involves setting a first groove on the outer wall of a cylinder, with the cross-sectional shape of the first groove being circular to match the object. The cross-sectional shape of the stabilizing groove is set to arc shape to make one side of the outer wall of the locking block fit against the object. The addition of a sliding rod restricts the movement trajectory of the sliding sleeve. The addition of a spring allows the fixing plate to return to its original position. The addition of a connecting rod increases the stability of the movable rod. The addition of a sliding groove allows the movable rod to swing. The addition of a connecting rod limits the swing amplitude of the movable rod. This microscope LED illumination source is easy to install when connected to a microscope, minimizing damage to the microscope objective.
[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] 1. It contains multiple small, active structures, resulting in higher costs;
[0006] 2. It does not have a focusing function. Utility Model Content
[0007] To overcome the above deficiencies, this application provides a microscope illumination device aimed at improving the problems mentioned in the background art.
[0008] This application provides a microscope illumination device, including a cylindrical illumination mechanism that is fitted onto a lens. A lens mechanism is screwed to the lower end of the illumination mechanism, and a locking ring is screwed to the upper end of the illumination mechanism. An elastic body is held between the locking ring and the illumination mechanism, and the elastic body is pressed against the outer circumference of the lens.
[0009] In one specific implementation, the lighting mechanism includes a cylindrical body, a ring lamp is provided on the lower end face of the cylindrical body, and a thread is provided on the outer circle of the cylindrical body.
[0010] In the above implementation process, the ring light is an LED light group, which is embedded in the lower end face of the cylinder to form ring lighting.
[0011] In one specific embodiment, the lens mechanism includes an outer cylinder and an annular convex lens, the outer cylinder being screwed to the outer circle of the cylinder body, and the convex lens being snapped onto the lower end of the outer cylinder.
[0012] In the above process, the convex lens is installed on the ring lamp head by screwing the outer cylinder to the cylinder body, and the distance between the convex lens and the ring lamp is adjusted by rotating the outer cylinder, thereby adjusting the focusing effect of the light and realizing the focusing function.
[0013] In one specific embodiment, the lens mechanism further includes an inner cylinder, a connecting rod is fixedly connected between the outer cylinder and the inner cylinder, and the convex lens is snapped between the outer cylinder and the inner cylinder.
[0014] In the above process, the outer cylinder and the inner cylinder are fixed together by a connecting rod to form an annular groove structure, which protects the inner wall of the ring lamp and the convex lens and reduces the entry of foreign objects.
[0015] In one specific implementation, sealing rings are provided on both the inner and outer walls of the cylinder to abut against the outer cylinder and the inner cylinder.
[0016] In the above process, the sealing ring plays a sealing role to prevent moisture and foreign objects from entering, and the sealing ring achieves locking after focusing by the frictional resistance between the sealing ring and the outer and inner cylinders.
[0017] In one specific implementation, a filter is magnetically attached to the end face of the outer cylinder.
[0018] In the above process, the filter filters the light beam of the ring light to produce a light beam of a specific color band, which illuminates the target object. The filter is magnetically attached to the end face of the outer and inner cylinders, making it easy to replace.
[0019] In one specific embodiment, the elastomer includes a rigid cylinder inserted into the inner wall of the cylinder, and elastic conical rings are fixedly connected to both ends of the rigid cylinder, the conical rings abutting against the outer circle of the lens.
[0020] In the above implementation process, the rigid cylinder is used to connect the two conical rings into a whole. During assembly, the elastic body is inserted into the cylinder and then the locking ring is put on, which is very convenient. In this embodiment, both the rigid cylinder and the conical ring are engineering plastic supports. A rubber pad is covered inside the conical ring to increase the friction on the outer circle of the lens and improve the stability of the installation.
[0021] In one specific implementation, both the cylinder and the locking ring are provided with abutment rings that abut against the conical ring.
[0022] In the above process, when the locking ring is tightened, the locking ring and the abutment ring on the cylinder press against the conical ring, bringing them closer together and reducing the inner diameter, thereby pressing the outer circle of the lens tightly, which can accommodate lens sizes within a certain range.
[0023] Compared with the prior art, the advantages of this application are: the rotating lens mechanism adjusts the distance with the lighting mechanism to achieve the focusing effect; the rotating locking ring and the lighting mechanism together clamp the elastomer, causing it to expand towards the inner wall and press against the outer circle of the lens to achieve the installation and fixation effect, and it is not easy to damage the lens; the overall components are few and the operation is simple.

Detailed Implementation
[0030] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0031] Please see Figures 1-4This application provides a microscope illumination device, including a cylindrical illumination mechanism 10, which is fitted onto a lens. A lens mechanism 20 is screwed to the lower end of the illumination mechanism 10, and a locking ring 30 is screwed to the upper end of the illumination mechanism 10. An elastic body 40 is clamped between the locking ring 30 and the illumination mechanism 10, and the elastic body 40 is pressed against the outer circumference of the lens. The distance between the rotating lens mechanism 20 and the illumination mechanism 10 is adjusted to achieve a focusing effect. Rotating the locking ring 30 together with the illumination mechanism 10 clamps the elastic body 40, causing it to expand inwards and press against the outer circumference of the lens for a secure installation. This method minimizes damage to the lens, has few components, and is simple to operate.
[0032] Please see Figures 1-4 The lighting mechanism 10 includes a cylindrical body 11, with a ring light 12 disposed on the lower end face of the cylindrical body 11, and threads disposed on the outer circumference of the cylindrical body 11. The ring light 12 is an LED light group, embedded in the lower end face of the cylindrical body 11, forming ring lighting.
[0033] Please see Figures 1-4 The lens mechanism 20 includes an outer cylinder 21 and an annular convex lens 22. The outer cylinder 21 is screwed to the outer circle of the cylinder body 11, and the convex lens 22 is snapped onto the lower end of the outer cylinder 21. The convex lens 22 is mounted on the head of the ring lamp 12 by screwing the outer cylinder 21 to the cylinder body 11, and the distance between the convex lens 22 and the ring lamp 12 is adjusted by rotating the outer cylinder 21, thereby adjusting the focusing effect of the light and realizing the focusing function.
[0034] Please see Figures 1-4 The lens mechanism 20 also includes an inner cylinder 23, and a connecting rod 24 is fixedly connected between the outer cylinder 21 and the inner cylinder 23. The convex lens 22 is snapped between the outer cylinder 21 and the inner cylinder 23. The outer cylinder 21 and the inner cylinder 23 are fixed together by the connecting rod 24 to form an annular groove structure, which protects the inner wall of the ring lamp 12 and the convex lens 22 and reduces the entry of foreign objects.
[0035] Please see Figures 1-4 The inner and outer walls of the cylinder 11 are provided with sealing rings 13 that abut against the outer cylinder 21 and the inner cylinder 23. The sealing rings 13 serve to seal and prevent moisture and foreign objects from entering. The frictional resistance between the sealing rings 13 and the outer cylinder 21 and the inner cylinder 23 also helps to lock the cylinder after focusing.
[0036] Please see Figures 1-4 A filter 25 is magnetically attached to the end face of the outer cylinder 21. The filter 25 filters the beam of the ring lamp 12 to produce a beam of a specific color wavelength that illuminates the target object. The filter 25 is magnetically attached to the end faces of the outer cylinder 21 and the inner cylinder 23, making it easy to replace.
[0037] Please see Figures 1-4The elastomer 40 includes a rigid cylinder 41, which is inserted into the inner wall of the cylinder 11. Flexible conical rings 42 are fixedly connected to both ends of the rigid cylinder 41, and the conical rings 42 abut against the outer circumference of the lens. The rigid cylinder 41 connects the two conical rings 42 into a single unit. During assembly, the elastomer 40 is simply inserted into the cylinder 11, and then the locking ring 30 is placed on top. This is very convenient. In this embodiment, both the rigid cylinder 41 and the conical rings 42 are engineering plastic supports. A rubber pad is placed inside the conical rings 42 to increase friction against the outer circumference of the lens and improve installation stability.
[0038] Please see Figures 1-4 Both the barrel 11 and the locking ring 30 are provided with abutting rings 14 that abut against the conical ring 42. When the locking ring 30 is tightened, the locking ring 30 and the abutting ring 14 on the barrel 11 press against the conical ring 42, bringing them closer together and reducing the inner diameter, thereby pressing the outer circle of the lens tightly, which can accommodate lens sizes within a certain range.
[0039] The working principle of this microscope illumination device is as follows: The cylinder 11 is fitted onto the lens. Rotating the locking ring 30 causes the locking ring 30 and the abutment ring 14 on the cylinder 11 to press against the conical ring 42, bringing them closer together and reducing the inner diameter. This tightens the outer circle of the lens, achieving a fixed installation. Rotating the locking ring 30 allows for focusing. When focusing is needed, rotating the outer cylinder 21 adjusts the distance between the convex lens 22 and the ring lamp 12, thus adjusting the focusing effect. The sealing ring 13 provides a seal, preventing moisture and foreign objects from entering between the ring lamp 12 and the inner wall of the convex lens 22. The frictional resistance between the sealing ring 13 and the outer cylinder 21 and inner cylinder 23 helps lock the lens after focusing. In summary, rotating the lens mechanism 20 adjusts the distance to the illumination mechanism 10, achieving a focusing effect. Rotating the locking ring 30 together with the illumination mechanism 10 clamps the elastic body 40, causing it to expand inwards and press against the outer circle of the lens, achieving a fixed installation effect without easily damaging the lens. The overall design has few parts and is simple to operate.
