[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] In an embodiment of the present invention, a standardized insulin injection education rotary drum comprises a first rotary drum 1, a second rotary drum 2, and a needle observation module 3. The first rotary drum 1 is used for needle selection and injection, and the second rotary drum 2 is used for needle identification. The first rotary drum 1 and the second rotary drum 2 have the same structure and are both provided with a transparent display shell 8 and a text content shell 14 for display. The needle observation module 3 cooperates with the first rotary drum 1 and the second rotary drum 2 to determine whether the needle is reused. The first rotary drum 1 or the second rotary drum 2 comprises a top cover 7, a transparent display shell 8, a partition plate 9, a middle plate 10, a magnifying glass 11, a rotating ring 12, a center column 13, a text content shell 14, and a bottom plate 15. The top cover 7, the middle plate 10, and the bottom plate 15 are made of a hard material such as plastic and can support and separate the entire device. The transparent display shell 8 is made of a transparent material such as transparent plastic and can transmit light and protect the displayed items. The transparent display shell 8 is connected to the top cover 7 and the rotating ring 12 by a snap. The partition plate 9 is made of a hard material such as plastic, which plays a role of partitioning. In addition, mounting holes can be left on the partition plate 9 according to the requirements of the exhibits to support the exhibits. Corresponding text patterns can be printed on the partition plate 9 according to the requirements of the exhibit content.

[0027] The material of the magnifying glass 11 is glass, acrylic or other light-transmitting materials, and a Fresnel magnifying glass can also be used instead (Fresnel magnifying glass, also known as Fresnel lens, is a special optical element invented by French physicist Augustin Fresnel. The surface of this lens is covered with tiny stripes, forming a vortex structure, which contains many convex lenses (also known as ring-shaped). When light passes through the Fresnel lens, due to the presence of these tiny stripes, the light will bend and produce diffraction, thereby forming a magnified image. The main difference between a Fresnel magnifying glass and an ordinary magnifying glass is its ultra-thin feature. The minimum thickness of a Fresnel magnifying glass made of materials such as PVC can be between 0.45mm and 0.90mm, which makes it lighter and more portable. In addition, the brightness of the Fresnel lens is higher than that of an ordinary lens, the surface is smoother, and the radiation area is larger. The working principle of the Fresnel lens is based on the refraction and diffraction of light. Each tiny groove can be regarded as a The Fresnel magnifier has many uses in practical applications. For example, the Fresnel lens used in a lighthouse can focus light on one point to form a strong beam of light for indicating the direction of travel. In addition, Fresnel lenses are also widely used in projection systems, focusing systems, and security monitoring. In short, the Fresnel magnifier is a special optical element with the characteristics of ultra-thinness, high brightness, and large radiation area. It magnifies the image through the refraction and diffraction of light and is widely used in many fields. The user can observe the exhibits in the transparent display shell 8 more clearly through the magnifying glass 11.

[0028] The rotating ring 12 is made of a hard material such as plastic and is used to secure the magnifying glass 11. It connects the transparent display housing 8 and the text content housing 14 via a snap fit. The inner ring of the rotating ring 12 features a slot that aligns with the protrusion on the center column 13. This slot, leveraging the material's toughness, limits the rotation angle, ensuring alignment between the magnifying glass 11 and the displayed object. A recessed outer surface of the rotating ring 12 facilitates rotation during use.

[0029] The material of the central column 13 is a hard material such as plastic, and is used to support and connect the middle plate 10 and the bottom plate 15. A protrusion is provided on the upper part, and the shape is consistent with the slot of the rotating circle 12.

[0030] The text content shell 14 is made of a hard material such as plastic, and corresponding text patterns can be printed on the text content shell 14 according to the display content requirements.

[0031] The rotating bearing 16 is fixed in the slot of the bottom plate 15 and provides the rotation function for the two rotating drums. The magnet 17 is fixed to the inner ring of the rotating bearing and provides magnetic fixation. The top cover 7, middle plate 10, and bottom plate 15 form the support structure of the first rotating drum 1 or the second rotating drum 2. The transparent display shell 8 protects and displays exhibits and is fixedly connected to the top cover 7 or rotating ring 12 respectively via buckles. The surface of the partition plate 9 is provided with holes to fix exhibits. The magnifying glass 11 is fixedly connected to the rotating circle 12 and is used to display the contents of the transparent display shell 8. The central column 13 is supported and connected to the middle plate 10 and the bottom plate 15. The needle observation module 3 includes a display screen 18, a circuit board 19, an amplifying module 20, a power supply module 21, a light-emitting back panel 22 and a shell 23. The display screen 18 is used to display the captured image of the amplifying module 20. The circuit board 19 is electrically connected to the display screen 18, the amplifying module 20, the power supply module 21 and the light-emitting back panel 22. A magnifying camera for capturing images is provided in the amplifying module 20. The power supply module 21 supplies power to the needle observation module 3 as a whole. The light-emitting back panel 22 is used to adjust the light of the needle observation module 3. The shell 23 is used to fix the needle. One side of the shell 23 is used to fix the needle, and the other side is fixedly connected to the baffle 4.

[0032] The display screen 18 is used to display the image captured by the lens of the magnification module 20. The circuit board 19 transmits data and issues commands, connecting the display screen 18, the magnification module 20, the power supply module 21, and the light-emitting backplane 22. The magnification module 20 contains a magnifying camera with a preset focal length. The power supply module 21 supplies power to the entire needle observation module 3. The light-emitting backplane 22 houses a white LED light and is coated with a smooth, white, translucent frosted film to ensure uniform background lighting. The housing 23 is made of a hard material such as plastic and has a groove on its top. The groove is sized to match the standard insulin needle size and is used to secure the insulin needle at the preset focal length. The housing 23 is secured to the baffle 4 via a snap. The inner ring of the rotating ring 12 is provided with a slot that mates with the center column 13. The center column 13 also has a protrusion that mates with the slot. The toughness of the rotating ring 12 allows the device to be rotated and positioned, and it also facilitates alignment between the magnifying lens 11 and the displayed object.
