Abstract
Description
Technical Field
[0001] This utility model relates to the field of goggle testing technology, specifically a goggle abrasion resistance test structure. Background Technology
[0002] As an essential protective item, safety goggles inevitably come into contact with various objects during use, resulting in scratches on their surface. Scratches not only affect the aesthetics of the goggles but can also interfere with the user's vision, reducing the user experience and safety. Therefore, after the goggles are manufactured, their lenses must undergo abrasion resistance testing to ensure product quality.
[0003] However, existing goggle abrasion resistance testing devices typically only use a single object to scratch the goggle surface, making it difficult to simulate the diverse wear and tear caused by goggles coming into contact with objects of varying roughness in real-world use. Since goggles may encounter friction from objects of different materials and roughness in actual use, resulting in scratches of varying depth and shape, the simplistic nature of existing testing methods leads to incomplete test results. These results fail to fully reflect the abrasion resistance performance of goggles under complex usage environments and lack accuracy in practical applications. Utility Model Content
[0004] This invention addresses the technical problems existing in the prior art by providing a goggle abrasion resistance test structure to solve the problem that the single nature of existing test methods results in a lack of comprehensiveness and cannot fully reflect the abrasion resistance performance of goggles in complex usage environments.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A goggle abrasion resistance test structure, comprising: Testing equipment; A friction contact assembly is mounted on a testing machine. The friction contact assembly includes a rotatable pulley and multiple contact elements with different roughnesses. The multiple contact elements are arranged around the pulley in the circumferential direction and on the outer edge of the pulley. A linear module, located on the pulley axis and mounted on the testing machine, is used for displacement along a direction close to the pulley; A limiting component is disposed on the moving end of the linear module for fixing the goggles.
[0006] The beneficial effects of this utility model are: 1) This test structure uses a rotatable pulley and multiple contact parts with different roughness in the friction contact assembly. Combined with the linear module driving the goggles fixed on the limiting assembly to move towards the pulley, the rotation of the pulley allows the goggles to scrape against the contact parts with different roughness in sequence, thereby realizing the automated testing of the wear resistance of the goggles surface. It can not only accurately simulate the wear under different friction conditions, but also comprehensively cover a variety of friction scenarios that may be encountered in actual use by setting multiple roughness contact parts, which greatly improves the comprehensiveness and authenticity of the wear resistance test.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, the friction contact assembly also includes a servo motor, a support frame, a spindle, and a bushing. The support frame is fixed to the top of the testing machine, the servo motor is fixed on the support frame, and the bushing is located on one side of the servo motor and is mounted on the support frame.
[0009] Furthermore, one end of the spindle is coaxially fixed to the drive end of the servo motor, and the other end of the spindle passes through the bushing and is coaxially fixed to one side of the pulley.
[0010] The beneficial effect of adopting the above-mentioned further solution is that the servo motor drives the spindle to rotate, which in turn drives the pulley to rotate at an angle, thereby enabling quick and accurate switching between contact parts with different roughness and the goggles, improving the switching efficiency during the testing process.
[0011] Furthermore, the plurality of contact elements respectively include sandpaper of 320 grit, 400 grit, 600 grit, 800 grit, 1000 grit, 1400 grit, and 2000 grit.
[0012] The beneficial effect of adopting the above-mentioned further solution is that by setting sandpaper with various roughnesses such as 320 grit, 400 grit, 600 grit, 800 grit, 1000 grit, 1400 grit and 2000 grit as contact elements on the pulley, the wear environment under different friction intensities and surface roughness conditions can be simulated for the goggles, meeting the testing requirements for the wear resistance performance of the goggles, improving the flexibility and applicability of the test, and providing reliable support for the comprehensive evaluation of the wear resistance performance of the goggles surface.
[0013] Furthermore, the limiting component includes a support plate and a clamp, the support plate being fixed on the slider of the linear module, and the clamp being fixed on the top of the support plate.
[0014] Furthermore, the clamp is a vertical clamp.
[0015] The advantage of adopting the above-mentioned further solution is that it ensures that the goggles will not fall off or shift when they rub against the sandpaper on the pulley during the test. The vertical clamps can provide uniform and reliable clamping force, which enhances the positional stability of the goggles.
[0016] Furthermore, the pulley has an oval cross-section along its radial direction.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the cross-section of the pulley along its radial direction is designed as an oval shape, so that the sandpaper on the pulley can protrude moderately, which facilitates the full contact between the goggles and sandpaper with different roughness and optimizes the simulation effect of friction conditions during the test.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0021] As an essential protective item, safety goggles inevitably come into contact with various objects during use, resulting in scratches on their surface. Scratches not only affect the aesthetics of the goggles but can also interfere with the user's vision, reducing the user experience and safety. Therefore, after the goggles are manufactured, their lenses must undergo abrasion resistance testing to ensure product quality.
[0022] However, existing goggle abrasion resistance testing devices typically only use a single object to scratch the goggle surface, making it difficult to simulate the diverse wear and tear caused by goggles coming into contact with objects of varying roughness in real-world use. Since goggles may encounter friction from objects of different materials and roughnesses in actual use, resulting in scratches of varying depth and shape, the simplistic nature of existing testing methods leads to incomplete results that fail to fully reflect the abrasion resistance performance of goggles under complex usage environments and lack accuracy in practical applications. Therefore, the inventor has proposed a goggle abrasion resistance testing structure to address these issues.
[0023] The present invention provides the following preferred embodiments. like Figure 1 and Figure 2 As shown, a goggle abrasion resistance test structure includes: 100 testing machines; Friction contact assembly 400 is mounted on the testing machine 100. The friction contact assembly 400 includes a rotatable pulley 401 and multiple contact elements 402 with different roughness. The multiple contact elements 402 are arranged around the pulley 401 in the circumferential direction and on the outer edge of the pulley 401. Linear module 200 is located on the axis of pulley 401 and is set on the test machine 100 for displacement along the direction close to pulley 401. Limiting component 300 is disposed on the moving end of linear module 200 and is used to fix the goggles; This test structure uses a rotatable pulley 401 and multiple contact elements 402 with different roughness in the friction contact assembly 400. Combined with the linear module 200 driving the goggles fixed on the limiting assembly 300 to move towards the pulley 401, the rotation of the pulley 401 allows the goggles to scrape against the contact elements 402 with different roughness on the pulley 401 in sequence. This achieves automated testing of the wear resistance of the goggles surface. It can not only accurately simulate the wear under different friction conditions, but also comprehensively cover a variety of friction scenarios that may be encountered in actual use by setting multiple roughness contact elements 402, which greatly improves the comprehensiveness and authenticity of the wear resistance test.
[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the friction contact assembly 400 also includes a servo motor 403, a support frame 406, a main shaft 405, and a bushing 404. The support frame 406 is fixed on the top of the test machine 100, the servo motor 403 is fixed on the support frame 406, the bushing 404 is located on one side of the servo motor 403 and is set on the support frame 406, one end of the main shaft 405 is coaxially fixed on the drive end of the servo motor 403, and the other end of the main shaft 405 passes through the bushing 404 and is coaxially fixed on one side of the pulley 401. The servo motor 403 drives the spindle 405 to rotate, which in turn drives the pulley 401 to rotate at an angle. This enables the contact switching between the contact parts 402 with different roughness and the goggles to be achieved quickly and accurately, thus improving the switching efficiency during the testing process.
[0025] In this embodiment, as Figure 1 and Figure 2As shown, multiple contact elements 402 include sandpaper with various roughnesses such as 320 grit, 400 grit, 600 grit, 800 grit, 1000 grit, 1400 grit, and 2000 grit. By setting sandpaper with various roughnesses such as 320 grit, 400 grit, 600 grit, 800 grit, 1000 grit, 1400 grit, and 2000 grit as contact elements 402 on the pulley 401, the wear environment under different friction intensities and surface roughness conditions can be simulated for the goggles, meeting the testing requirements for the wear resistance of the goggles, improving the flexibility and applicability of the test, and providing reliable support for the comprehensive evaluation of the wear resistance of the goggles surface.
[0026] In this embodiment, as Figure 1 and Figure 2 As shown, the limiting component 300 includes a support plate 301 and a clamp 302. The support plate 301 is fixed on the slider of the linear module 200, and the clamp 302 is fixed on the top of the support plate 301. The clamp 302 adopts a vertical clamp to ensure that the goggles will not fall or shift when they rub against the sandpaper on the pulley 401 during the test. The vertical clamp can provide a uniform and reliable clamping force, which enhances the positional stability of the goggles.
[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the cross-section of pulley 401 along its radial direction is oval. Designing the cross-section of pulley 401 along its radial direction as oval allows the sandpaper on pulley 401 to protrude moderately, facilitating full contact between the goggles and sandpaper of different roughness, and optimizing the simulation effect of friction conditions during the test.
[0028] The specific working process of this utility model is as follows: (1) Place the goggles to be tested. First, place the goggles on the support plate 301, and then use vertical clamps to tighten the goggles.
[0029] (2) Conduct abrasion resistance test The goggles fixed on the support plate 301 are driven by the linear module 200 to move towards the pulley 401. As the goggles approach and come into contact with the 320-grit sandpaper on the bottom of the pulley 401, the goggles are scraped against one of the sandpapers.
[0030] (3) Test with different types of sandpaper. The servo motor 403 drives the spindle 405 to rotate, which in turn drives the pulley 401 to rotate at an angle, so that the next piece of sandpaper, namely 400 grit sandpaper, is at the bottom of the pulley 401. Then, the goggles fixed on the support plate 301 are driven by the linear module 200 to move towards the pulley 401.
[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
