Description

Technical Field

[0001] This utility model relates to the field of color vision detection technology, specifically a color blindness and color weakness detection disc. Background Technology

[0002] Color blindness and color weakness are common visual impairments that affect people's ability to perceive and distinguish colors. In order to help people with color blindness and color weakness better integrate into social life and improve their quality of life, color blindness and color weakness test panels are usually used to test their color vision.

[0003] However, in real life, traditional color blindness and color weakness testing discs are easily affected by external factors when testing patients' color vision, resulting in lower accuracy and fairness in the testing of color blindness and color weakness patients. Secondly, when using traditional color blindness and color weakness testing discs, the testers often touch and handle the pseudo-isochromatic images on the discs for extended periods, which can easily cause unnecessary damage to the pseudo-isochromatic images, resulting in a shorter lifespan for the testing discs. At the same time, traditional color blindness and color weakness testing discs have low functionality, which is not conducive to testing different types of patients, thus causing testers to waste a lot of time during the testing process, resulting in low testing efficiency for patients with color blindness and color weakness. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a color blindness and color weakness detection disc.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides a color blindness and color weakness detection disk, including a storage mechanism, a privacy protection mechanism, an adjustment mechanism and a detection mechanism. The storage mechanism is provided with a storage bucket at the bottom, a cover plate at the top of the storage bucket, an observation hole at one side of the top of the cover plate, the privacy protection mechanism at the top of the observation hole, the adjustment mechanism at the middle of the storage bucket, a push plate at the top of the adjustment mechanism, and the detection mechanism at the top of the push plate.

[0006] Preferably, the placement bucket has a cylindrical structure with a hollow center and a slit on the outer wall.

[0007] Preferably, the anti-peeping mechanism has a support plate at the bottom, which is welded to the top of the cover plate. A rotating rod is connected to the top center of the support plate via a rotating shaft. The top of the rotating rod is welded to a baffle, which has a cylindrical structure and is positioned above the observation hole.

[0008] Preferably, a first motor is installed at the bottom of the adjustment mechanism, and a rotating plate is movably connected to the top of the first motor via a rotating shaft. Both the rotating plate and the push plate are cylindrical structures.

[0009] Preferably, a hydraulic cylinder is bolted to the center of the top of the rotating plate, and a hydraulic rod is connected to the top of the hydraulic cylinder. The top of the hydraulic rod is bolted to the center of the bottom of the push plate.

[0010] Preferably, the detection mechanism is located at the bottom of the cover plate, and a support frame is provided at the bottom of the detection mechanism. The support frame has a "U" shaped structure, and a second motor is installed on the top of the outer wall of the support frame. One end of the second motor is movably connected to a turntable through a rotating shaft. The turntable has a cylindrical structure, and several grooves are provided at equal intervals on both sides of the turntable.

[0011] The beneficial effects of this utility model are:

[0012] 1. By activating the first motor at the bottom of the adjustment mechanism, the motor drives the rotating plate to rotate, facilitating the sequential rotation of the false isochromatic images pasted in the grooves of the turntable to the observation hole for the tester to observe. On the one hand, this not only facilitates a more comprehensive assessment of the tester's color perception ability but also reduces the time spent by the tester during the color blindness and color weakness testing process, further improving the efficiency of the tester's color blindness and color weakness testing. On the other hand, by observing the different false isochromatic images on the turntable, the tester reduces the possibility of human contact with the false isochromatic images, thus avoiding unnecessary damage to the false isochromatic images caused by prolonged touching by different testers, thereby extending the service life of the test disc. At the same time, the baffle at the top of the anti-peeping mechanism blocks the observation hole, ensuring that the false isochromatic images on the turntable can only be observed by the tester, preventing outsiders from pointing out the flaws, further improving the accuracy and fairness of the test.

[0013] 2. The hydraulic cylinder on the adjusting mechanism drives the push plate at the top of the hydraulic rod to move up and down, facilitating the adjustment of the height of the detection mechanism. On the one hand, this helps to bring the pseudo-isochromatic images for detecting color blindness symptoms in the grooves closer to the observation hole, making it easier for the examiner to detect color blindness symptoms. On the other hand, it allows the examiner to focus more intently on observing the pseudo-isochromatic images in each groove, avoiding interference from external objects. Simultaneously, by adjusting the height of the turntable through the adjusting mechanism, and in conjunction with activating the second motor on the detection mechanism, the second motor drives the turntable to move. On the one hand, this facilitates aligning the other side of the color weakness detection turntable with the observation hole, allowing the examiner to simultaneously perform color blindness and color weakness detection through the detection turntable, making the detection turntable more functional. On the other hand, by adjusting the height and angle of the turntable, it allows the examiner to observe from different distances and angles, which helps to better simulate actual conditions and ensure the reliability of the test results.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-Figure 5 As shown, the present invention discloses a color blindness and color weakness detection disc, comprising a storage mechanism 1, a privacy protection mechanism 2, an adjustment mechanism 3, and a detection mechanism 4. The storage mechanism 1 has a storage container 101 at its bottom and a cover plate 102 at its top. The cover plate 102 is connected to the storage container 101 by bolts. An observation hole 103 is provided on one side of the top of the cover plate 102. The privacy protection mechanism 2 is located on top of the observation hole 103. The adjustment mechanism 3 is located in the middle of the storage container 101. A push plate 305 is provided on top of the adjustment mechanism 3. The detection mechanism 4 is located on top of the push plate 305.

[0023] The placement bucket 101 has a cylindrical structure with a hollow center. A cutout 104 is provided on the outer wall of the placement bucket 101 to facilitate daily maintenance of the testing mechanism 4.

[0024] The anti-peeping mechanism 2 has a support plate 201 at its bottom, which is welded to the top of the cover plate 102. A rotating rod 202 is connected to the top center of the support plate 201 via a rotating shaft. The top of the rotating rod 202 is welded to a baffle 203, which has a cylindrical structure and is positioned above the observation hole 103. By using the baffle 203 at the top of the anti-peeping mechanism 2 to block the observation hole 103, the false color image on the turntable 403 can only be observed by the inspector, thus avoiding the possibility of outsiders pointing out the error and further improving the accuracy and fairness of the inspection.

[0025] A first motor 301 is installed at the bottom of the adjustment mechanism 3. A rotating plate 302 is movably connected to the top of the first motor 301 via a rotating shaft. Both the rotating plate 302 and the push plate 305 are cylindrical structures. By turning on the first motor 301 at the bottom of the adjustment mechanism 3, the first motor 301 drives the rotating plate 302 to rotate, which facilitates the sequential rotation of the false isochromatic images pasted in the grooves 404 on the turntable 403 to the observation hole 103 for the tester to observe. On the one hand, this not only helps to more comprehensively assess the tester's color discrimination ability, but also reduces the time spent by the tester in the process of testing for color blindness and color weakness, further improving the tester's efficiency in testing for color blindness and color weakness. On the other hand, by observing the different false isochromatic images on the turntable 403, the tester reduces the situation of human contact with the false isochromatic images, thereby avoiding unnecessary damage to the false isochromatic images caused by prolonged contact by different testers, which in turn helps to extend the service life of the test table.

[0026] A hydraulic cylinder 303 is bolted to the top center of the rotating plate 302. A hydraulic rod 304 is connected to the top of the hydraulic cylinder 303. The top of the hydraulic rod 304 is bolted to the bottom center of the push plate 305. The hydraulic cylinder 303 on the adjusting mechanism 3 drives the push plate 305 on the top of the hydraulic rod 304 to move up and down, which facilitates the adjustment of the height of the detection mechanism 4. On the one hand, it is beneficial to bring the pseudo-isochromatic images of each color blindness symptom in the groove 404 closer to the observation hole 103, making it easier for the examiner to detect color blindness symptoms. On the other hand, it is beneficial for the examiner to observe the pseudo-isochromatic images in each groove 404 more focusedly, avoiding the examiner being affected by external objects.

[0027] The detection mechanism 4 is located at the bottom of the cover plate 102. A support frame 401 is provided at the bottom of the detection mechanism 4. The support frame 401 has a "U"-shaped structure. A second motor 402 is installed on the top of the outer wall of the support frame 401. One end of the second motor 402 is movably connected to a turntable 403 via a rotating shaft. The turntable 403 has a cylindrical structure. Several grooves 404 are evenly spaced on both sides of the turntable 403. These grooves 404 are positioned directly above the observation hole 103 via an adjustment mechanism 3. The turntable is adjusted by the adjustment mechanism 3. The height of 403 is adjusted, and in conjunction with the second motor 402 on the detection mechanism 4, the second motor 402 drives the turntable 403 to move. On the one hand, this makes it easier to align the other side of the color-blindness detection turntable 403 with the observation hole 103, which is beneficial for the examiner to conduct color blindness and color weakness tests simultaneously through the detection disc, making the detection disc more functional. On the other hand, by adjusting the height and angle of the turntable 403, the examiner can observe from different distances and angles, which helps to better simulate the actual situation and ensure the reliability of the test results.

[0028] In use, firstly, the pseudo-isochromatic images used to detect color weakness and color blindness are respectively affixed to several grooves 404 on both sides of the turntable 403. By activating the first motor 301 at the bottom of the adjustment mechanism 3, the first motor 301 drives the rotating plate 302 to rotate, which facilitates the sequential rotation of the pseudo-isochromatic images affixed to each groove 404 on the turntable 403 to the observation hole 103 for the tester to observe. On the one hand, this not only helps to more comprehensively assess the tester's color discrimination ability, but also reduces the time spent by the tester in the process of detecting color blindness and color weakness, further improving the tester's efficiency in detecting color blindness and color weakness. On the other hand, by observing different pseudo-isochromatic images on the turntable 403, the tester reduces the situation of human contact with the pseudo-isochromatic images, thereby avoiding unnecessary damage to the pseudo-isochromatic images caused by prolonged contact by different testers, which in turn helps to extend the service life of the test table.

[0029] Then, the observation hole 103 is blocked by the baffle 203 on the top of the anti-peeping mechanism 2, ensuring that the false same-color image on the turntable 403 can only be observed by the tester, avoiding the situation of outsiders reminding the tester, and further improving the accuracy and fairness of the test.

[0030] Finally, the hydraulic cylinder 303 on the adjusting mechanism 3 drives the push plate 305 at the top of the hydraulic rod 304 to move up and down, which facilitates the adjustment of the height of the detection mechanism 4. On the one hand, this helps to bring the pseudo-isochromatic images for detecting color blindness symptoms in the grooves 404 closer to the observation hole 103, making it easier for the examiner to detect color blindness symptoms. On the other hand, it allows the examiner to focus more intently on observing the pseudo-isochromatic images in each groove 404, avoiding interference from external objects. At the same time, the height of the turntable 403 is adjusted by the adjusting mechanism 3, and the second motor 402 on the detection mechanism 4 is activated. The second motor 402 drives the turntable 403 to move. On the one hand, this makes it easier to align the other side of the color weakness detection turntable 403 with the observation hole 103, allowing the examiner to perform color blindness and color weakness detection simultaneously through the detection disc, making the detection disc more functional. On the other hand, by adjusting the height and angle of the turntable 403, the examiner can observe from different distances and angles, which helps to better simulate the actual situation and ensure the reliability of the test results.
