[0029] Since the digital slit lamp microscope is limited by its own structure and the inherent characteristics of the optical system when performing external eye photography tasks, it generally adopts a single-eye sequential shooting mode, which not only has a complicated and cumbersome operation process and low efficiency, but also easily leads to inconsistent image information due to the time difference in binocular shooting, thereby seriously interfering with the doctor's accurate judgment of the disease. An auxiliary shooting support for a digital slit lamp microscope is developed and designed, and the specific scheme is as follows:

[0030] As shown in Figures 1-5 An auxiliary shooting support for a digital slit lamp microscope, comprising a base 1, a connecting mechanism 2 and a lens mounting part 7, the base 1 is installed at the lower end of the connecting mechanism 2, the lens mounting part 7 is installed at the upper end of the connecting mechanism 2, the connecting mechanism 2 can be adjusted in multiple directions, and a plurality of lens mounting grooves 701 are formed in the lens mounting part 7.

[0031] As shown in Figure 1 The connecting mechanism 2 is a multi-joint component, the connecting mechanism 2 comprises a support part 201 and a connecting part 202, the connecting part 202 is hingedly connected to the upper end of the support part 201, and the connecting part 202 is provided with at least one hinge joint 203. In this embodiment, the hinge joint 203 is a hinge joint 203 with a built-in spring. The support part 201 is made of high-strength aluminum alloy material, and the surface is subjected to hard anodizing treatment, having excellent wear resistance and corrosion resistance. The connecting part 202 is connected to the upper end of the support part 201 through the hinge joint 203. The hinge joint 203 rotates smoothly and maintains a self-holding state, and can realize large-angle pitch adjustment.

[0032] As shown in Figure 1As shown, the connecting part 202 is provided with a plurality of hinge joints 203 with built-in springs, and the hinge joints 203 are provided with dampening. Each hinge joint 203 is designed for independent adjustment, and the user can adjust the damping force according to the actual use requirements. The hinge joint 203 is internally provided with a butterfly spring group, and cooperates with a precisely processed limiting mechanism, which not only ensures a smooth feeling during adjustment, but also can realize reliable positioning at any angle. When the user adjusts the connecting mechanism 2 to the target position, the built-in spring system will automatically lock the current angle, ensuring that accidental displacement will not occur under normal use conditions. The structure of the damping hinge joint 203 can refer to the existing damping hinge joint 203, and therefore no redundant description is made.

[0033] In other schemes, each hinge joint 203 is provided with an angle scale and a positioning indicator, supporting precise angle adjustment and repeated positioning.

[0034] The multi-joint connecting mechanism 2 not only realizes quick and accurate positioning adjustment, but also greatly improves the operation efficiency and user experience due to the humanized design, and is particularly suitable for application scenarios that require frequent adjustment of the shooting angle.

[0035] As shown in the figure, Figure 1 The support part 201 is a telescopic rod structure, which is used to adjust the height of the support rod. The height of the support part 201 required by the user can be satisfied through lifting adjustment. A three-section nested structure is adopted, that is, a sleeve and two telescopic sections are included, so that stepless height adjustment within a certain length range can be realized. The telescopic rod is designed with a self-locking structure 204. Linearly distributed sawtooth structures are formed on the outer walls of the two telescopic sections in the telescopic rod. The outermost sleeve and the front end of the first telescopic section are both provided with elastic press switches. The front end of the elastic press switch is elastically engaged with the sawtooth structure, so as to fix the telescopic section, so that the telescopic section can maintain stability at any height. In other schemes, a self-locking structure 204 of the prior art can also be used to ensure the stability of the telescopic rod.

[0036] The telescopic rod structure not only realizes quick and accurate height adjustment, but also improves the operation convenience, and perfectly adapts to the requirements of diversified shooting scenes.

[0037] As shown in the figure, Figure 2 The lens mounting part 7 and the connecting mechanism 2 are designed with a ball head connection. The side of the lens mounting part 7 close to the connecting mechanism 2 is provided with a ball head connection end 5. The ball head is made of high-strength stainless steel material, and the surface is polished to ensure smooth rotation and wear resistance. Correspondingly, the upper end of the connecting mechanism 2 is provided with a matching ball socket fastening part. The part is composed of a fixed joint 3, a sliding sleeve 4 and a fastening spring 301, forming a high-efficiency and reliable quick adjustment and locking system.

[0038] As shown in the figure, Figure 2As shown, the front end of the fixed joint 3 adopts an umbrella-shaped structure design, provided with six evenly distributed arc-shaped fixing plates 302, and each fixing plate inner wall is inlaid with a high-friction coefficient wear-resistant gasket to ensure that the contact surface with the ball head connecting end 5 can provide sufficient friction and will not damage the surface of the ball head. The front end of the fastening spring 301 is in close contact with the rear end of the sliding sleeve 4, and the rear end is fixed in the fixed joint 3, providing stable pre-tightening force. The sliding sleeve 4 is made of engineering plastic material, and the inner wall is provided with a guide groove to ensure smooth sliding without shaking.

[0039] When angle adjustment is needed, the user only needs to pull the sliding sleeve 4 backward with one hand, and the sliding sleeve 4 moves backward to compress the fastening spring 301, while releasing the constraint on the arc-shaped fixing plate 302, so that the ball head connecting end 5 is in a freely adjustable state. At this time, the lens mounting part 7 can be flexibly adjusted at multiple angles to meet different shooting needs. After adjustment is completed, the sliding sleeve 4 is loosened, and the elastic force of the fastening spring 301 pushes the sliding sleeve 4 to move forward, and the tapered inner wall of the front end of the sliding sleeve 4 presses the arc-shaped fixing plate 302, so that it tightly fits the outer wall of the ball head connecting end 5, realizing reliable locking.

[0040] As shown in Figure 1 , the outer part of the sliding sleeve 4 is provided with anti-skid texture and operation indication mark, which is convenient for users to quickly identify the operation direction. The whole adjustment process does not need tools and can be completed with one hand, which significantly improves the operation efficiency and user experience. The design not only realizes fast and accurate angle adjustment, but also provides a solid guarantee for high-quality imaging with reliable locking performance, which is an ideal choice for precision optical equipment auxiliary support.

[0041] As shown in Figure 1 , 5 , the base 1 adopts a solid metal plate to achieve counterweight design. The base 1 includes an upper and lower clamping plate, one side of the clamping plate is provided with a mounting hole for connecting with the lower part of the connecting mechanism 2, and the side of the mounting hole facing upward protrudes outward, which ensures that the clamping plate and the connecting mechanism 2 are more stable. In this embodiment, the clamping plate includes an upper clamping plate 101 and a lower clamping plate 102, and the surfaces of the two are treated by hard anodizing, which has excellent wear resistance and corrosion resistance. The upper clamping plate 101 is designed as a through-hole, and the inner wall is polished to ensure smooth cooperation with the connecting mechanism 2 without gaps. The lower clamping plate 102 adopts an internally threaded round hole to ensure precise screwing with the external threads of the lower part of the connecting mechanism 2. The edge of the clamping plate adopts a rounded design to improve safety and increase comfort. The lower part of the connecting mechanism 2 is designed as an external thread structure and is screwed with a fixed sleeve 205. When the clamping plate is adjusted to the right position, the lower end of the fixed sleeve 205 can be brought into abutment with the upper surface of the upper clamping plate 101 by turning the fixed sleeve 205, so that the upper and lower clamping plates 101 and 102 complete the clamping of the table plate. It can be used for clamping table plates of different thickness specifications and is simple to use.

[0042] As Figure 1 , 2 , shown in FIG. 3, the lens mounting component 7 is a semicircular frame structure to facilitate the quick installation of a circular lens. The user can simply place the circular lens in the lens mounting groove 701 on the semicircular frame structure, and the lens can be quickly and efficiently disassembled and assembled, improving the use efficiency. Specifically, the curvature of the semicircular frame structure is calculated to perfectly match the curvature of the standard circular lens, ensuring the stability and fit of the lens during installation. The frame body is made of high-strength lightweight aluminum alloy material, and the surface is treated by anodizing to ensure the structural strength and achieve lightweight design. On the inner edge of the semicircular frame, there is a lens mounting groove 701 that can securely fix the lens.

[0043] The inner wall of the mounting groove is inlaid with a silica gel gasket, which can play a buffering and protecting role. The opening of the frame adopts a horn-shaped guide design to facilitate the quick positioning and installation of the lens. The user only needs to gently push the circular lens along the opening, and the lens will automatically slide into the mounting groove and be securely in place. The entire process can be completed in only 2-3 seconds. When disassembling, the user can easily remove the lens by grabbing the edge of the lens. The operation is simple and quick, and it is suitable for scenarios that require frequent lens replacement, such as ophthalmic examinations, microscopic photography, etc., which can greatly improve work efficiency and user experience.

[0044] As Figure 4 shown, a sliding mechanism 6 is provided between the ball head connecting end 5 and the main body of the lens mounting component 7. The sliding mechanism 6 includes a mounting bracket, a precision screw 602, a sliding block 603, and a knob 601. The outside of the knob 601 is provided with anti-slip patterns, so that the user can finely adjust the knob 601. The mounting bracket is integrated with the ball head connecting end 5. The precision screw 602 is screwed to the ends of the mounting bracket, and the knob 601 is mounted on the front end of the precision screw 602. The sliding block 603 is fixedly connected to the main body of the lens mounting component 7 and is slidingly connected to the precision screw 602. Specifically, the mechanism is composed of a mounting bracket, a precision screw 602, a high-precision sliding block 603, and a knob 601, forming a highly efficient and reliable linear adjustment system. The mounting bracket is manufactured by integral molding process and is seamlessly connected to the ball head connecting end 5, ensuring the stability and durability of the overall structure. The mounting bracket is provided with connecting holes on both sides for connecting the precision screw 602.

[0045] The precision screw 602 is made of high-quality alloy steel and is hardened and precisely ground on the surface to ensure smooth cooperation with the sliding block 603. The sliding block 603 is made of self-lubricating composite material and is internally embedded with ball bearings to form a low-friction cooperation with the precision screw 602, ensuring a smooth and smooth adjustment process.

[0046] As Figure 1 , 3As shown, the slider 603 is fixedly connected with the main body of the lens mounting component 7 through high-strength bolts, and a lock washer is arranged at the connection position to ensure that loosening does not occur during frequent adjustment, and the needs of most use scenarios can be met. During adjustment, the user only needs to rotate the knob 601 to realize fine forward and backward movement of the lens mounting component 7, and the system can be automatically locked after adjustment is completed, without the need for additional fixing operation.

[0047] In addition, as shown in Figure 1 、 2 , 4, the outer part of the sliding mechanism 6 is provided with a dustproof protective shell 604, which can effectively prevent dust and impurities from entering and affecting the adjustment accuracy. It is suitable for scenes that require fine focusing, such as microscopic photography and precision detection, and can significantly improve work efficiency and imaging quality.

The arrangement of the antiskid pad 103 can ensure that the clamping plate can provide reliable clamping force in various working conditions.

[0049] Usage instructions:

[0050] First, adjust the clamping plate to clamp the edge of the table plate, then tighten the fixing sleeve 205 to complete the clamping of the clamping plate on the table plate, and then adjust the height of the required supporting part 201. After adjusting the height, adjust the pitch angle of the connecting part 202, so that the lens position is located between the digital slit lamp microscope and the eye of the detector. In the case of lens position deviation, loosen the ball head connecting end 5, then adjust the lens position, and adjust the front and rear positions of the lens through different rotation directions of the knob 601 to meet the required focal length.

[0051] The utility model has the following advantages:
