Description

Technical Field

[0001] This utility model belongs to the field of pupil focusing technology, and specifically relates to an adaptive focusing ring for a pupil sensor. Background Technology

[0002] A pupillary sensor is a tool used in preoperative examinations. This handheld device is used to accurately measure the diameter of the pupil. Because the pupil reflects infrared light differently than its surroundings, the pupillary sensor can accurately determine the starting point of the pupil and measure its diameter. Typically, the measurement is taken with the lights on first, and then with the lights off, so that the doctor can observe the change in the patient's pupil size.

[0003] In the existing technology, pupil sensors with adaptive focusing are not convenient to be flexibly installed in different scenarios and devices. They are mostly customized, which involves a large investment in customization and has limited use. If a pupil sensor is found to have an incorrect installation hole position during unified debugging and installation, it is necessary to wait for a customized delivery cycle before it can be installed and used, which is inconvenient and limited. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adaptive focusing ring for the pupil sensor.

[0009] Preferably, the protruding snap-fit ​​blocks are located at the bottom of the embedded mounting block and are evenly spaced, and one end of the protruding snap-fit ​​blocks forms a snap-fit ​​inclined surface.

[0010] Preferably, the snap-fit ​​plate and the protruding snap-fit ​​block are used in a snap-fit ​​manner, and both sides of the bottom of the snap-fit ​​plate are formed with mating contact surfaces, which are used in conjunction with the snap-fit ​​inclined surface for contact and mating.

[0011] Preferably, the second fixing block and the embedded mounting block are fixedly connected to each other, and the two second fixing blocks are rotatably connected by a shaft that passes through the first fixing block, and the shaft is fixedly connected to the first fixing block.

[0030] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0032] refer to Figures 1-6The pupil sensor adaptive focusing ring includes an adaptive sensor body 1. Mounting plate 101 and mounting plate 202 are respectively provided at the top and bottom of the adaptive sensor body 1. Embedding slides 201 are provided at both the top and bottom of the adaptive sensor body 1. An embedding mounting block 2 located inside the embedding slide 201 is fixedly installed at one end of each mounting plate 101 and mounting plate 202. Multiple protruding snap-fit ​​blocks 3 are fixedly installed inside the embedding slide 201. A snap-fit ​​plate 4 is provided on one side of the embedding mounting block 2. A fixing block 5 is fixedly installed on the top of one side of the snap-fit ​​plate 4. Fixing blocks 5 are located on both sides of the fixing block 5. Each component is equipped with a fixing block 501, and an adjusting connecting plate 6 is fixedly installed on the top of the snap-fit ​​plate 4. In use, the flexible snap-fit ​​adjustment of the snap-fit ​​plate 4 and multiple protruding snap-fit ​​blocks 3 can increase the flexibility of the adaptive sensor body 1 in use, making the mounting socket 103 easier to adjust to match the installation position of external devices. Moreover, this adjustment is made without moving the adaptive sensor body 1, reducing the requirements and limitations of the adaptive sensor body 1 on the installation environment. It can be flexibly applied to multiple installation scenarios without customization, and has a wide market response effect.

[0033] Mounting plate 101 and mounting plate 2 are symmetrically designed, and the two embedded mounting blocks 2 are also symmetrically designed. Mounting plate 101 and mounting plate 2 are used in conjunction with the adaptive sensor body 1 for installation. The symmetrical design of mounting plate 101 and mounting plate 2 102 helps to ensure the balance of both sides of the adaptive sensor body 1.

[0034] Both mounting plate 101 and mounting plate 102 have mounting holes 103 on their inner sides. The mounting holes 103 are elliptical in shape and are used to insert external bolts. The elliptical shape allows the external mounting bolts to be finely adjusted longitudinally within the holes.

[0035] Both sides of the embedded mounting block 2 are fixedly mounted with sliders 202. The interior of the adaptive sensor body 1 is provided with grooves 203 located on both sides of the embedded slide 201. The grooves 203 are used to slide in conjunction with the sliders 202. The sliding connection between the sliders 202 and the grooves 203 will guide the movement of the embedded mounting block 2.

[0036] The protruding snap-fit ​​blocks 3 are located at the bottom of the embedded mounting block 2 and are evenly spaced. One end of the protruding snap-fit ​​blocks 3 forms a snap-fit ​​inclined surface 301. The protruding snap-fit ​​blocks 3 are evenly spaced in the embedded slide 201, and the snap-fit ​​friction on one side is increased by the protruding design of the snap-fit ​​inclined surface 301.

[0037] The snap-fit ​​plate 4 and the protruding snap-fit ​​block 3 are used to engage with each other. Both sides of the bottom of the snap-fit ​​plate 4 have mating contact surfaces 401, which engage with the snap-fit ​​inclined surface 301. When the mating contact surface 401 of the snap-fit ​​plate 4 contacts the snap-fit ​​inclined surface 301 of the protruding snap-fit ​​block 3, the engagement between the snap-fit ​​plate 4 and the mating contact surface 401 is stable. The mating contact surface 401 on the other side helps reduce contact friction between the snap-fit ​​plate 4 and the protruding snap-fit ​​block 3 during the rotation of the snap-fit ​​plate 4 around the shaft 502.

[0038] Fixed block 2 501 is fixedly connected to embedded mounting block 2. The two fixed blocks 2 501 are rotatably connected by a shaft 502 that passes through fixed block 1 5. The shaft 502 is fixedly connected to fixed block 1 5. The rotation of fixed block 1 5 will drive the shaft 502 to rotate. The bearing facilitates the smooth rotation of shaft 502 inside fixed block 2 501. Fixed block 2 501 supports shaft 502 and fixed block 1 5.

[0039] Both ends of the shaft 502 are fitted with torsion springs 503. The two ends of the torsion springs 503 are fixedly connected to the first fixed block 5 and the second fixed block 501 respectively. When the shaft 502 rotates, it will drive the torsion springs 503 to twist. The rebound of the torsion springs 503 will ensure that the first fixed block 5 returns to its initial position.

[0040] Brief description of the usage process: When the operator needs to adjust the position of mounting plate 101 and mounting plate 202 on the surface of the adaptive sensor body 1, the adjusting connecting plate 6 can be moved towards the embedded mounting block 2. The adjusting connecting plate 6 drives the snap-fit ​​plate 4 to rotate around the shaft 502. At this time, the snap-fit ​​plate 4 changes, and its mating contact surface 401 cancels the snap-fit ​​tilting surface 301. At this time, the snap-fit ​​force between the snap-fit ​​plate 4 and the protruding snap-fit ​​block 3 can be released. The mating contact surface 401 on the other side facilitates the snap-fit ​​plate 4 to reduce the contact friction between the snap-fit ​​plate 4 and the protruding snap-fit ​​block 3 during the rotation of the snap-fit ​​plate 4 around the shaft 502. Meanwhile, the operator can move mounting plate 101 or mounting plate 202, and the embedded mounting block 2 moves in the embedded slide 201. The slider 202 and the slide groove 203 cooperate to guide its movement. When the mounting plate 101 or mounting plate 202 is moved to the required position, and the mounting hole 103 is matched with the required installation position, the operator can directly release the force applied to the adjusting connecting plate 6. At this time, the torsion spring 503 loses its force and, under the rebound action, drives the snap-fit ​​plate 4 back to the initial state. At this time, the snap-fit ​​plate 4 is vertical and snaps with the protruding snap-fit ​​block 3, realizing the stability of the embedded mounting block 2 after adjustment.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
