[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] When shooting continuously or recording video, frequently adjusting the focus manually not only significantly reduces work efficiency but also makes users feel tired.

[0022] In view of this, the present invention provides an external mobile phone lens microlens adjustable focus microscopic imaging device. Through the coordinated work of components such as a drive motor, drive rod, first bevel gear, second bevel gear, threaded rod, and moving frame, it can automatically and accurately adjust the focus. This design not only effectively solves the problem of reduced work efficiency and user fatigue caused by frequent manual adjustment of focus during continuous shooting or video recording, but also ensures the stability and accuracy of the focusing process, greatly improving the operating experience and work efficiency.

[0023] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0024] Example 1: By Figure 1 , 3 As shown in 4 and 5, an external mobile phone lens microlens adjustable focusing microscopic imaging device includes a carrier 1, a housing 2 attached to the top of the carrier 1, a lens frame 3 fixedly connected to one side of the housing 2, a fixed lens 4 fixedly connected to the inner wall of the lens frame 3, and a movable lens 5 disposed on the inner wall of the housing 2. The external mobile phone lens microlens adjustable focusing microscopic imaging device also includes a focusing device 6, a clamping device 9, and an adjusting device 10. The focusing device 6 is installed between the housing 2 and the movable lens 5; the clamping device 9 is installed between the carrier 1 and the housing 2; and the adjusting device 10 is installed outside the lens frame 3. The focusing device 6 adjusts the distance between the movable lens 5 and the fixed lens 4, the clamping device 9 fixes the carrier 1 and the housing 2, and the adjusting device 10 protects the lens frame 3 and adjusts different filters. The fixed lens 4 and the movable lens 5 can be convex lenses. The two convex lenses can converge light, and by adjusting the distance between them, the position of light convergence can be changed, thereby achieving focal length adjustment. The fixed convex lens can first focus the light to form an image of the object, and the adjustable convex lens can further focus the light to make the image on the mobile phone's image sensor clearer. When the device is finished using it, it should be placed in a suitable position manually to prevent impurities and dust from entering the device.

[0025] In the specific implementation process, it is worth noting that the carrier 1 described in this embodiment is a mobile phone or other mobile terminal device that can be used for shooting, such as a tablet computer, and is not a component of the technical solution described in this application. For the convenience of recording and describing the technical solution, it is explained that the focusing device 6 adjusts the distance between the moving lens 5 and the fixed lens 4, thereby achieving continuous and fine focusing, so that the operator can quickly and accurately find a clear imaging position and improve observation efficiency. The clamping device 9 fixes the carrier 1 and the shell 2, and can fix different mobile phones. The adjusting device 10 protects the lens frame 3, can protect the lens frame 3, and can switch different filters to eliminate glare and reflection and meet different observation needs.

[0026] Furthermore, the focusing device 6 includes a drive motor 61, a battery 62, a drive rod 63, a first bevel gear 64, a second bevel gear 65, a threaded rod 66, and a moving frame 67. The drive motor 61 is fixedly connected to the top of the housing 2; the battery 62 is fixedly connected to the top of the housing 2 and is located in front of the drive motor 61; the drive rod 63 is fixedly connected to the drive end of the drive motor 61 and is rotatably connected to the inner wall of the housing 2 through a sealed bearing; two first bevel gears 64 are provided, respectively fixedly connected to the upper and lower outer walls of the drive rod 63; the second bevel gear 65 is meshed with the outer wall of the first bevel gear 64; the threaded rod 66 is fixedly connected to the inner wall of the second bevel gear 65 and is connected to the inner wall of the drive rod 65. The inner wall of the housing 2 is rotatably connected; the movable frame 67 is threadedly connected to the outer wall of the threaded rod 66 and is movably connected to the inner wall of the housing 2; wherein, the drive motor 61 drives the movable frame 67 to move laterally through the cooperation of the drive rod 63, the first bevel gear 64, the second bevel gear 65 and the threaded rod 66; wherein the battery 62 supplies power to the drive motor 61; wherein the battery 62 also includes a switch, which is set on the connection circuit between the battery 62 and the drive motor 61, for controlling the start and stop of the drive motor 61; at the same time, an overcharge and over-discharge protection module is also provided in the connection circuit between the battery 62 and the drive motor 61 to protect the safe operation of the battery 62 and the drive motor 61;

[0027] In the specific implementation process, it is worth noting that the drive motor 61 transmits power to the first bevel gear 64 fixed thereon via the drive rod 63. The two first bevel gears 64 are connected to the second bevel gear 65 through meshing, causing the threaded rod 66 to rotate. Subsequently, the moving frame 67 is threadedly connected to the outer wall of the threaded rod 66 and rotates with it. However, because it is movably connected to the inner wall of the housing 2, it will move laterally as the threaded rod 66 rotates. During this process, the battery 62 is responsible for providing the required power to the drive motor 61, ensuring the smooth operation of the entire focusing process, thereby achieving... For precise focusing of the device, and to facilitate the replenishment of the battery 62, a charging port is provided on its exterior. This charging port has a simple and practical design and is compatible with common charging cables. Users only need to connect one end of the charging cable to the charging port and the other end to a power source to charge the battery 62. At the same time, to allow users to clearly understand the charging status of the battery 62, a charging indicator light is specially provided next to the charging port. When the charging indicator light is red, it indicates that the battery 62 is charging in progress; when the charging indicator light turns green, it indicates that the battery 62 has completed charging and can supply power to the device at any time, ensuring the normal operation of the focusing system and the entire device.

[0028] Furthermore, the clamping device 9 includes a clamping plate 91, an adjusting rod 92, anti-slip pads 93, and limiting rods 94. The clamping plate 91 is located on the side of the housing 2 away from the lens frame 3. The adjusting rod 92 is rotatably connected to the housing 2 via a bearing, and its outer wall is threadedly connected to the clamping plate 91. Two anti-slip pads 93 are provided, respectively snapped onto the upper and lower surfaces of the clamping plate 91. Two limiting rods 94 are provided, respectively inserted into both sides of the clamping plate 91, and pass through the clamping plate 91 to be fixedly connected to the housing 2. The clamping force of the clamping plate 91 on the carrier 1 and the housing 2 is adjusted by rotating the adjusting rod 92. The anti-slip pads 93 increase friction to achieve a better fixing effect. The limiting rods 94 provide guidance and limitation for the clamping plate 91. The clamping plate 91 is directly connected to the carrier 1. The component that contacts and generates clamping force can clamp or release the carrier 1 by changing its relative position with the housing 2. The anti-slip pad 93 increases the friction between the clamping plate 91 and the carrier 1, preventing the housing 2 from sliding relative to the carrier 1 during use and improving the stability of the fixation. The anti-slip pad 93 is made of rubber material, which has good elasticity and anti-slip performance. The surface has anti-slip texture, which can effectively increase the friction with the carrier 1. The surface of the limiting rod 94 is chrome-plated to improve its hardness and wear resistance and reduce friction loss with the clamping plate 91. The clamping plate 91 is made of high-strength aluminum alloy material, which has high strength and light weight, and can withstand large clamping force without easily deforming.

[0029] In the specific implementation process, it is worth noting that when the adjusting rod 92 is rotated, the clamping plate 91 moves radially on the housing 2, thereby changing the distance between it and the carrier 1, and thus adjusting the magnitude of the clamping force. In addition, in order to enhance the stability of clamping, two anti-slip pads 93 are respectively installed on the upper and lower inner walls of the clamping plate 91 to increase friction, while two limiting rods 94 are installed on both sides of the clamping plate 91 to ensure that the position of the clamping plate 91 is stable during the adjustment process, avoiding tilting or excessive sliding, and ensuring the accuracy and firmness of clamping the carrier 1 and the housing 2. Throughout the process, the anti-slip pads 93 and the limiting rods 94 work together to ensure a good fixing effect and provide necessary guidance and limitation, so that the clamping device 9 can effectively fix the carrier 1 and the housing 2, achieving the stability and accuracy requirements of clamping.

[0030] Specifically, when using this external mobile phone lens microlens adjustable focus microscopic imaging device, the drive motor 61 drives the drive rod 63, which in turn transmits power to the fixed first bevel gear 64. Through the meshing of the first bevel gear 64 and the second bevel gear 65, the threaded rod 66 rotates. The moving frame 67 is threadedly connected to the threaded rod 66 and rotates together. However, due to its movable connection with the inner wall of the housing 2, it will move laterally. This process is powered by the battery 62 to ensure smooth power transmission and achieve precise focusing. At the same time, rotating the adjusting rod 92 can make the clamping plate 91 move radially along the housing 2 to adjust the distance between it and the carrier 1 and change the clamping force. The anti-slip pad 93 is installed on the inner wall of the clamping plate 91 to increase friction and enhance stability. The limiting rod 94 is installed on both sides of the clamping plate 91 to ensure its position is stable during movement and prevent tilting or excessive sliding. The anti-slip pad 93 and the limiting rod 94 together ensure the stability and accuracy of clamping and effectively fix the carrier 1 and the housing 2.

[0031] Example 2: From Figure 1 , 2As shown in points 3 and 5, the adjustment device 10 includes a housing 101, an opening 102, a turntable 103, and a rotating rod 104. The housing 101 is located on the side of the lens frame 3 away from the carrier 1. The opening 102 is formed on the outer wall of the housing 101. The turntable 103 is rotatably connected to the inner wall of the housing 101. The rotating rod 104 is fixedly connected to the outer wall of the turntable 103 and extends to the outside of the housing (101) through a rubber pad. The housing 101 is mounted on the lens frame 3, the opening 102 is aligned with the opening of the lens frame 3, and the turntable 103 and the rotating rod 104 are connected, making it more convenient to change the filter. The housing 101 serves as the main outer shell of the adjustment device 10, protecting the internal structure and... The housing 101 serves as a mounting base for other components, and its positional design facilitates mating with the lens frame 3. The outer wall of the lens frame 3 has threads, and the inner wall of the housing 101 has internal threads that match the threads on the outer wall of the lens frame 3, allowing filter replacement operations to be performed closer to the lens. The turntable 103 is a key component for convenient filter replacement; it rotates within the housing 101. By pre-installing multiple different types of filters on the turntable 103, rotating it allows users to switch between different filters to the corresponding positions on the lens, thus achieving rapid filter replacement. The rotating rod 104 provides the operating interface for the rotation of the turntable 103. By rotating the rotating rod 104, the user can drive the turntable 103, which is fixedly connected to it. The rotating rod 104 rotates to switch filters. A rubber pad ensures the rotation of the rotating rod 104 while preventing dust, moisture, and other external impurities from entering the device through the connection between the rotating rod 104 and the housing 101, thus affecting the filters or other components. The filters are mounted on the turntable 103 via a snap-fit ​​structure. The turntable 103 has a positioning groove, and the protrusions on the edge of the filters engage with the positioning groove to ensure accurate filter placement and prevent displacement during the rotation of the turntable 103. The outer wall of the rotating rod 104 has anti-slip textures to increase friction between the user's hand and the rotating rod 104, facilitating more stable rotation. Furthermore, the length and diameter of the rotating rod 104 are ergonomically designed. The design makes the rotation operation more comfortable and effortless. The cover 101 is fixed to the lens frame 3 by means of threaded connection or bolt connection. This connection method makes it convenient to disassemble the cover 101 when needed to maintain or further adjust the internal structure. A protruding limiting block is provided on the inner wall of the cover 101 at the position corresponding to the turntable 103. When the turntable 103 rotates to a specific angle, the limiting block cooperates with the limiting groove on the turntable 103 to limit the turntable 103 from continuing to rotate, ensuring that the filter can accurately stop at the position corresponding to the lens. Rubber sealing rings are provided on the edge of the cover 101 and at the opening 102 to further enhance the sealing of the device and prevent external impurities from entering and affecting the use of the filter.

[0032] In the specific implementation process, it is worth noting that the cover 101 is fixed to the lens frame 3. The outer wall of the cover 101 has an opening 102. When in use, the opening 102 is aligned with the lens of the mobile phone. The inner wall of the cover 101 is provided with a rotatable turntable 103. The turntable 103 is connected to the rotating rod 104 fixed on the cover 101 through a sealed bearing, so that the turntable 103 can be easily rotated to select different filter positions. This allows for quick filter replacement without disassembling the cover 101, improving the flexibility and convenience of the device, simplifying the operation process, making the filter replacement process more concise, and protecting the lens frame 3 by setting the cover 101.

[0033] Furthermore, slide rails 7 are slidably engaged on both the upper and lower sides of the outer wall of the movable frame 67. The slide rails 7 are fixedly connected to the inside of the housing 2. The end of the drive rod 63 away from the drive motor 61 extends to the outside of the housing 2 through a sealed bearing and is fixedly connected to a handwheel 8. The handwheel 8 provides a convenient way to rotate the drive rod 63. In the absence of an external power supply or when manual adjustment is required, the user can rotate the drive rod 63 by turning the handwheel 8. This, in turn, adjusts the position of the movable frame 67 through a series of transmission components, including the first bevel gear 64, the second bevel gear 65, and the threaded rod 66. The handwheel 8 increases the operating torque, allowing the user to rotate the drive rod 63 more easily, thus improving the convenience and operability of the operation. Lubricant is applied to the sliding contact surface between the slide rails 7 and the movable frame 67. Grease is used to reduce friction and ensure that the moving frame 67 can slide smoothly on the slide rail 7, while reducing wear on parts and extending the service life of the device. The surface of the handwheel 8 is provided with anti-slip texture to increase the friction between the hand and the handwheel 8 and prevent the hand from slipping during operation. The diameter and thickness of the handwheel 8 are ergonomically designed to make the grip more comfortable and the rotation operation more effortless. The slide rail 7 is fixed to the inside of the housing 2 by bolts or welding to ensure that the slide rail 7 can stably guide the moving frame 67 during movement and will not shift or loosen. A protective cover is provided around the handwheel 8 and fixed to the housing 2 to protect the handwheel 8 from damage caused by external impact and to prevent accidental injury to the user during operation.

[0034] In the specific implementation process, it is worth noting that when the drive motor 61 is started, the drive rod 63 drives the moving frame 67 to slide on the track inside the housing 2. When the drive motor 61 is damaged, the operator can control the movement position of the moving frame 67 by rotating the drive rod 63 through the handwheel 8, which is easy to operate.

[0035] Specifically, based on the above embodiment one, the cover 101 is fixed to the lens frame 3. The outer wall of the cover 101 has an opening 102 for aligning with the mobile phone lens. The inner wall has a rotating turntable 103, which is connected to the rotating rod 104 through a sealed bearing. This allows the turntable 103 to easily rotate and select different filter positions. Filters can be quickly changed without disassembling the cover 101, improving the flexibility and convenience of the equipment. In addition, the cover 101 can also protect the lens frame 3. When the drive motor 61 is started, the drive rod 63 drives the moving frame 67 to slide on the track of the housing 2. If the drive motor 61 is damaged, the operator can control the position of the moving frame 67 by rotating the drive rod 63 through the handwheel 8. The operation is simple and achieves the stability and accuracy requirements of clamping.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
