Description

Technical Field

[0001] This utility model relates to the field of protective lens technology, specifically a protective lens coating color difference observation box. Background Technology

[0002] Protective lenses are the core component of various protective glasses or face shields. They are specifically designed to provide critical safety protection for the wearer's eyes in work, experimentation, or specific environments. Unlike ordinary glasses, their core mission is to resist various physical or environmental hazards that may harm the eyes.

[0003] Existing protective lens coating color difference observation equipment includes an outer frame, on which a placement platform for placing the lens is set, and an observation window is set directly above the placement platform. Through the thin film interference effect between the observation window and the lens, when observing the lens through the observation window, the color uniformity is judged, thereby determining whether there is a color difference in the coating.

[0004] The above-mentioned technical conditions also have shortcomings: existing protective lens coating color difference observation equipment usually relies on external ambient light. Under insufficient light conditions, it is difficult to clearly observe the uniformity and color difference of the coating, resulting in inaccurate test results.

[0005] Based on this, this utility model designs a protective lens coating color difference observation box to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a protective lens coating color difference observation box to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective lens coating color difference observation box, including a base frame, a top frame fixedly connected to the top of the base frame, an observation window provided on the top frame, a light enhancement box provided inside the base frame, a light-transmitting part provided on the light enhancement box, a lens to be observed for color difference placed on the light-transmitting part, a support rod fixedly connected to the bottom of the inner wall of the light enhancement box, a crossbar fixedly connected to one side of the top of the support rod, and a lamp post connected to one end of the crossbar.

[0008] By adopting the above technical solution and integrating a light source, color difference observation can be performed even in relatively dim environments, thus improving the usability of the observation box.

[0009] Preferably, a drive motor is fixedly connected to the bottom of the inner wall of the light enhancement box, a worm gear is coaxially arranged on the output shaft of the drive motor, a stabilizing rod is rotatably connected to one side of the inner wall of the light enhancement box, a light shield is fixedly connected to one end of the stabilizing rod, the lamp post is located inside the light shield, and a worm wheel adapted to the worm gear is coaxially arranged on the stabilizing rod.

[0010] By adopting the above technical solution, the drive motor controls the rotation of the stabilizer bar through the precise transmission of the worm and worm wheel, making the angle of the light shielding sleeve adjustable, thereby dynamically changing the incident direction of the light from the lamp post and realizing multi-angle observation of the coating color difference.

[0011] Preferably, the light-shielding sleeve has a light-transmitting groove.

[0012] By adopting the above technical solution, the opening of the light-transmitting groove allows light to be emitted from a specific direction, which is convenient for focusing on the key area of ​​the lens and enhances the pertinence and clarity of chromatic aberration observation.

[0013] Preferably, the top frame is also provided with side plates inside.

[0014] By adopting the above technical solution, the transparent design of the side panel allows the observer to observe the protective lens from the side angle, forming an all-round perspective in combination with the observation window, thus improving the comprehensiveness and reliability of the observation.

[0015] Preferably, a handle is fixedly connected to one side of the light enhancement box, and four sets of casters are provided at the bottom of the base frame.

[0016] By adopting the above technical solution, the combination of handle and casters makes the equipment easy to move and position, adapting to different working environments and enhancing portability and ease of operation.

[0017] Preferably, the lamp post is an LED lamp bead, and its shape is cylindrical.

[0018] By adopting the above technical solution, cylindrical LED beads provide uniform circumferential illumination, simulating natural light conditions, ensuring stable light without dark areas, and improving the accuracy and consistency of coating color difference observation.

[0019] Preferably, the transmission ratio between the worm gear and the worm is 1:20.

[0020] By adopting the above technical solution, a transmission ratio of 1:20 is used to achieve high-precision angle control, avoid vibration during motor drive, and ensure smooth rotation of the sunshade sleeve.

[0021] In summary, this application has the following beneficial technical effects: by providing a stable and controllable lighting environment through the built-in lamp post and light enhancement box, it effectively overcomes the limitation of insufficient external light and ensures clear and reliable color difference observation; the drive motor and worm gear mechanism realize high-precision lighting angle adjustment, support multi-angle dynamic observation, and improve the comprehensiveness of coating uniformity evaluation; the handle and universal wheel design enhance the portability of the equipment and facilitate rapid deployment in different working scenarios.

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] A color difference observation box for protective lens coating includes a base frame 1, a top frame 2 fixedly connected to the top of the base frame 1, and an observation window 3 provided on the top frame 2. Through the thin-film interference of light between the observation window 3 and the protective lens, it is possible to see whether the coating on the surface of the protective lens is uniform. Inside the base frame 1, a light-enhancing box 4 is provided, and a light-transmitting part 5 is provided on the light-transmitting part 5. The lens to be observed for color difference is placed on the light-transmitting part 5, and then the internal structure of the light-enhancing box 4 provides illumination, which can provide auxiliary illumination when the indoor light is insufficient, thereby improving the detection effect. A support rod 11 is fixedly connected to the bottom of the inner wall of the light-enhancing box 4, and a crossbar 12 is fixedly connected to one side of the top of the support rod 11. A lamp post 13 is connected to one end of the crossbar 12. The lamp post 13 is connected to an external power supply and can generate simulated natural light, so that the color difference observation box can be used in low ambient light conditions.

[0028] Furthermore, a drive motor 9 is fixedly connected to the bottom of the inner wall of the light enhancement box 4. The drive motor 9 is a stepper motor, which can provide relatively precise control. A worm gear 10 is coaxially mounted on the output shaft of the drive motor 9. A stabilizing rod 14 is rotatably connected to one side of the inner wall of the light enhancement box 4. A light shield 15 is fixedly connected to one end of the stabilizing rod 14. The lamp post 13 is located inside the light shield 15. A worm wheel 16 adapted to the worm gear 10 is coaxially mounted on the stabilizing rod 14. The rotation of the worm gear 10 can drive the worm wheel 16 to rotate, thereby adjusting the angle of the light shield 15.

[0029] Furthermore, a light-transmitting groove 17 is provided on the light-shielding sleeve 15. After the light-shielding sleeve 15 is rotated at a certain angle, the position of the light-transmitting groove 17 changes, thereby changing the angle of light transmitted through the lamp post 13, so that the lens can be observed from different angles.

[0030] Furthermore, a side panel 6 is installed inside the top frame 2. The side panel 6 is made of transparent material, which makes it easy to observe the protective glasses from the side.

[0031] Furthermore, a handle 7 is fixedly connected to one side of the light enhancement box 4, and four sets of casters 8 are provided at the bottom of the base frame 1. The observation box can be moved well by the handle 7 and the casters 8, which makes it easy to use.

[0032] Furthermore, the lamp post 13 is an LED lamp bead, which is cylindrical in shape and can emit uniform light in all directions, thus facilitating subsequent dynamic detection.

[0033] Furthermore, the transmission ratio between the worm gear 16 and the worm 10 is 1:20, meaning that for every 20 rotations of the worm 10, the worm gear 16 rotates once, which enables more precise angle adjustment.

[0034] The implementation principle of this embodiment is as follows: the protective lens that needs to be observed for color difference is placed on the light-transmitting part 5 of the light-enhancing box 4, and uniform light is emitted by the lamp post 13 to simulate natural light. The light passes through the lens coating layer and produces a thin film interference effect, which displays a color difference pattern at the observation window 3 to intuitively judge the coating uniformity. The drive motor 9 drives the worm gear 10 to rotate, and the worm wheel 16 drives the stabilizing rod 14 to rotate, thereby adjusting the angle of the light shield 15. The position of the light-transmitting groove 17 changes to guide the light incident direction, so as to realize multi-angle dynamic observation.
