In real-world applications, dome covers are often exposed to complex and variable lighting environments with dynamically changing incident angles. Fixed-angle testing methods clearly cannot accurately reflect their overall performance in actual use. Utility Model Content

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1-5 As shown, the present invention provides a first embodiment of a device for adjusting the angle of a ball cover, including a chassis 1. The chassis 1 has fixing blocks 2 fixed at both the front and rear ends of its top. An installation platform 3 for mounting a ball cover 100 is provided between the two fixing blocks 2. The installation platform 3 is adjusted by an adjustment component 4, so that the angle of the ball cover 100 can be adjusted, which facilitates subsequent testing of different angles of the ball cover 100.

[0018] The adjustment component 4 includes a first rotating shaft 41 rotatably connected to the fixed block 2. The end of the first rotating shaft 41 near the mounting platform 3 penetrates the fixed block 2 and is fixedly connected to the mounting platform 3. The end of the first rotating shaft 41 away from the mounting platform 3 is fixed with a handle 42. The fixed block 2 has an arc-shaped opening 43. A bolt 44 is screwed onto the handle 42. The end of the bolt 44 near the mounting platform 3 passes through the arc-shaped opening 43 and is screwed onto the mounting platform 3.

[0019] Unscrew the two bolts 44, then rotate the two handles 42 around the corresponding first pivot 41, thereby rotating the mounting platform 3 and the ball cover 100 on the mounting platform 3, allowing the angle of the ball cover 100 to be adjusted. After adjusting the angle of the ball cover 100, screw the two bolts 44 into the threaded holes of the mounting platform 3 to fix the mounting platform 3.

[0020] Based on the first embodiment, this utility model provides a second embodiment of a device for adjusting the angle of the spherical cover. The fixing block 2 has an angle scale value 45. When it is necessary to adjust the angle of the spherical cover 100, it can be adjusted according to the angle scale value 45.

[0021] Based on any embodiment of the device with adjustable dome angle, the present invention provides a first embodiment of an optical index measuring device, including a measuring device 5. The measuring device 5 is a reflectance measuring instrument of model MSP-100 manufactured by Nanjing Shibuya Electron Beam Technology Co., Ltd. The reflectance measuring instrument is equipped with a measuring instrument body 51, a magnifying glass mount 52 and a computer 53.

[0022] The magnifying glass mount 52 includes a base 54, a support 55 is fixed to the top rear side of the base 54, and a magnifying glass 57 is mounted on the top of the support 55 via a mounting base 56. The magnifying glass 57 allows observation of whether the light spot is focused on the dome 100, which is convenient for subsequent measurements.

[0023] The support base 55 is provided with a placement platform 58, and the chassis 1 is placed on the placement platform 58.

[0024] The measuring instrument body 51 tests the optical properties of the spherical cover 100, which is placed on the stage 58 with the angle adjusted, and the computer 53 is used to receive the optical property information of the test.

[0025] Based on the first embodiment, this utility model provides a second embodiment of an optical index measuring device. The chassis 1 is adjusted to a horizontal position by a horizontal adjustment component 64 to ensure that the light beam can be incident vertically onto the dome 100. The horizontal adjustment component 64 includes a movable platform 61 slidably connected to a placement stage 58, and the chassis 1 is fixed to the top of the movable platform 61. A first rack 62 is fixed to the bottom of the placement stage 58. The first rack 62 meshes with a first gear 63. The first gear 63 is fixed on a second rotating shaft. The upper end of the second rotating shaft is rotatably connected to the movable platform 61, and the lower end is fixed to a first knob 65.

[0026] When it is necessary to adjust the horizontal position of the ball cover 100, rotate the first knob 65 to drive the gear to rotate on the rack, thereby driving the moving platform 61 to slide on the placement platform 58, which in turn can drive the chassis 1 and the ball cover 100 to move and adjust the horizontal position of the ball cover 100.

[0027] Based on any of the above embodiments, this utility model provides a third embodiment of an optical index measuring device. The placement stage 58 has its height adjusted by a height adjustment component 74 to ensure that the light spot is precisely focused on the dome 100, facilitating subsequent measurements. The height adjustment component 74 includes a lifting seat 71 fixed to the rear end of the placement stage 58. Two linear guide rails 72 are fixed on a support base 55, and the sliders of both linear guide rails 72 are fixedly connected to the rear end of the lifting seat 71. A second rack 73 is fixed on the support base 55 between the two linear guide rails 72. The second rack 73 meshes with a second gear 74, which is driven to rotate by a drive component 8. By driving the second gear 74 to rotate through the drive component 8, the lifting seat 71 is raised and lowered, which in turn raises and lowers the placement stage 58, which in turn raises and lowers the moving platform 61, and consequently raises and lowers the chassis 1 and the dome 100, adjusting the height of the dome 100. During this process, the linear guide rails 72 assist the lifting seat 71 in moving, ensuring stable raising and lowering of the lifting seat 71.

[0028] The drive assembly 8 includes a third rotating shaft 81 fixedly connected to the second gear 74, both ends of which are rotatably connected to the lifting seat 71. The lifting seat 71 has a mounting cavity 82, and a right-angle steering gear 83 is fixedly installed in the mounting cavity 82. One end of the third rotating shaft 81 is connected to the output end of the right-angle steering gear 83, and the input end of the right-angle steering gear 83 is connected to a fourth rotating shaft 84. The fourth rotating shaft 84 is rotatably connected to the inner wall of the mounting cavity 82. A worm gear 85 is fixed on the fourth rotating shaft 84, and the worm gear 85 is driven by a worm 86. Both ends of the worm 86 are rotatably connected to the inner wall of the mounting cavity 82. One end of the worm 86 penetrates the mounting cavity 82 and is fixedly connected to a second knob 87.

[0029] Rotating the second knob 87 causes the worm gear 86 to rotate, which in turn causes the worm wheel 85 to rotate, which in turn causes the fourth shaft 84 to rotate, which in turn causes the third shaft 81 to rotate, which in turn causes the second gear 74 to rotate.

[0030] The above description is only a preferred embodiment of the present utility model and should not be construed as a limitation of this application. All equivalent changes and modifications made within the scope of the patent application of the present utility model should be included in the scope of the present utility model.
