Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubricating grease performance testing technology, and in particular to a grease application device. Background Technology
[0002] Among numerous industrial products and mechanical devices, plastic materials are widely used in the manufacture of various parts due to their advantages such as light weight, corrosion resistance, and ease of processing, including automotive interior parts, electronic device housings, and medical device components. Lubricating grease, as a common lubricant, is used to reduce friction and wear between mechanical parts, extending equipment lifespan. However, when grease comes into contact with plastic parts, it can cause a series of problems. For example, the chemical components in the grease may cause swelling, softening, or corrosion of the plastic, leading to a decrease in the plastic's mechanical properties, cracking, deformation, and other phenomena, thus affecting the product's function and lifespan. Furthermore, incompatibility between grease and plastic can also cause problems such as discoloration, cracking, and stickiness on the plastic surface, affecting the product's appearance quality.
[0003] To ensure that plastic parts retain their original performance and appearance after contact with lubricating grease, plastic compatibility testing has emerged. By simulating actual usage environments, lubricating grease is brought into contact with plastic samples, and changes in the plastic's properties, such as dimensional stability, mechanical strength, and surface condition, are observed under specific conditions of time, temperature, and pressure. If the test results show that the plastic exhibits significant cracking, deformation, or other performance degradation after contact with the lubricating grease, it indicates that the lubricating grease is incompatible with the plastic, requiring replacement with another type of lubricating grease or modification of the plastic material. Conversely, if the plastic maintains its normal performance, it indicates good compatibility and safe application in actual products.
[0004] However, existing technologies still have many problems in the process of conducting plastic compatibility tests. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a grease application device that simplifies the grease application process, improves the consistency of coating thickness, and prevents cross-contamination between different greases.
[0006] To address the aforementioned problems, this utility model provides a grease application device for coating a sample with grease. The device includes a main body having a plurality of mutually independent grease reservoirs of the same depth. The main body is adapted to be configured to adhere to the sample, and the grease reservoirs expose the surface of the sample to be greased.
[0007] Optionally, it may also include a scraper portion adapted to be configured to scrape off the grease that overflows from the grease reservoir and adheres to the surface of the body portion.
[0008] Optionally, the scraper portion is slidably connected to the main body portion.
[0009] Optionally, the main body has grooves on its opposite sides; the scraper has sliders on its opposite sides; the sliders are fitted into the corresponding grooves to achieve a sliding connection between the scraper and the main body.
[0010] Optionally, the slider is a mushroom-shaped pin.
[0011] Optionally, the sample piece has a clamping portion at its end; each of the grease reservoirs has a contoured groove at its end, the contoured groove being adapted to accommodate the clamping portion.
[0012] Optionally, the scraper portion has a plurality of baffles, each baffle corresponding to the space between adjacent grease reservoirs.
[0013] Optionally, the scraper portion includes a handle.
[0014] Optionally, the main body has an arc-shaped structure to adapt to the surface of the clamp assembly used to fix the sample.
[0015] Optionally, the main body has 5 to 8 grease reservoirs.
[0016] Compared with the prior art, the technical solution of this utility model has the following advantages:
[0017] The grease application device of this utility model includes a main body with several mutually independent grease reservoirs of the same depth. The main body is adapted to be configured to adhere to the sample, and the grease reservoirs expose the surface of the sample to be greased. After the main body is adhered to the sample, grease is filled into each of the grease reservoirs, allowing the grease to adhere to the corresponding surface of the sample. This simplifies the grease application process, especially in testing scenarios involving multiple grease samples. Because the grease reservoirs are of the same depth, once each reservoir is filled with grease, uniform adhesion of the grease to the surface of each sample is achieved, and the control of the grease thickness is significantly improved, ensuring consistent coating thickness. The positioning of the grease reservoirs compacts the grease within each reservoir, increasing the adhesion between the grease and the sample and enhancing their bonding effect. Furthermore, since each grease reservoir is separate from the others, it can effectively prevent different greases from coming into contact with each other, thereby avoiding potential cross-contamination and providing more accurate and reliable experimental conditions for grease performance testing, ensuring the accuracy and repeatability of experimental results.
[0018] Furthermore, it also includes a scraper portion, which is adapted to be configured to scrape off the grease that overflows from the grease reservoir and adheres to the surface of the main body. By scraping off the grease that overflows from the grease reservoir and adheres to the surface of the main body using the scraper portion, the grease reservoirs are just filled with grease, thereby further improving the consistency of the grease thickness applied to each of the sample parts.
[0019] Furthermore, the scraper section is slidably connected to the main body. This sliding connection satisfies the movement requirements of the scraper section during the removal of excess grease, and also allows the scraper section and the main body to be assembled into a single unit. After the scraper section and the main body are assembled as a whole, the relative position and movement accuracy between them can be better controlled, thereby ensuring a uniform and consistent grease application thickness, meeting high-precision process requirements. Moreover, the integrated assembly method makes the overall size more compact, facilitating portability and storage, and improving the applicability and flexibility of the device.
[0020] Furthermore, the slider employs a mushroom-shaped pin. A mushroom-shaped pin is a common mechanical connecting component, resembling a mushroom in shape with a larger head and a thinner stem. In achieving a sliding connection, the head of the mushroom-shaped pin acts as a limit, preventing the connected components from detaching during sliding and ensuring connection stability. Secondly, its smooth surface and shape effectively reduce friction, making sliding smoother and reducing wear and energy loss. In addition, the mushroom-shaped pin has a simple structure, is easy to install and disassemble, and is easy to maintain and replace, saving time and costs. In a sliding connection, the mushroom-shaped pin can guide the components to move along a predetermined trajectory, preventing deviation from the track and improving motion accuracy.
[0021] Furthermore, the sample piece has a clamping portion at its end; each of the grease reservoirs has a contoured groove at its end, which is adapted to accommodate the clamping portion. The clamping portion is specifically designed at the end of the sample piece to facilitate clamping and fixing of the sample piece by the fixture assembly. Simultaneously, each grease reservoir has a contoured groove at its end, the shape of which matches the clamping portion to accommodate it. By embedding the clamping portion into the contoured groove, precise positioning between the grease reservoir and the sample piece can be quickly achieved. The advantage of this design lies in its efficiency and accuracy. The correspondence between the clamping portion and the contoured groove makes the installation process simple and quick, eliminating the need for complex alignment operations and greatly improving assembly efficiency. At the same time, this structure ensures precise attachment between the grease reservoir and the sample piece, with the grease reservoir accurately fitting the sample piece, providing a reliable structural foundation for subsequent grease application operations.
[0022] Furthermore, the scraper portion has a plurality of baffles, each baffle corresponding to the space between adjacent grease reservoirs. During the scraping process of the scraper portion removing excess grease, the grease overflowing from each grease reservoir is confined between two adjacent baffles, thereby avoiding cross-contamination between different types of grease in adjacent grease reservoirs.
[0023] Furthermore, the scraper section includes a handle. The handle allows technicians to easily control the movement of the scraper section, ensuring a more convenient, flexible, and precise operation. The handle design optimizes the user experience, improves work efficiency, and ensures operational stability. Attached Figure Description

[0029] As described in the background section, existing technologies still have many problems in the process of conducting plastic compatibility tests. These will be explained in detail below.
[0030] In previous plastic compatibility tests, there were some issues in the experimental procedures that urgently needed improvement, which had a potential impact on the accuracy and reliability of the test results.
[0031] First, a dedicated grease application device was lacking during the testing process. Since the thickness of the grease application is a key variable affecting test results, a suitable device can ensure that the grease is applied evenly and quantitatively to the surface of the plastic sample. However, due to the lack of suitable tools, the thickness of the grease sample was difficult to control precisely. This resulted in differences in the actual application conditions for different grease samples during testing, leading to inconsistent testing conditions. This inconsistency interferes with the accurate assessment of the interaction between the grease and the plastic, ultimately affecting the scientific validity and reliability of the assessment results.
[0032] Secondly, when testing multiple grease samples, the relatively small spacing between the plastic sample parts increases the difficulty of applying grease during multi-sample testing. In practice, due to space constraints, different greases may come into contact with each other when applying grease to different samples. Once contact occurs, cross-contamination may occur. This contamination alters the actual grease composition and state on the sample surface, further interfering with the accuracy of the test results and leading to biases in the assessment of grease compatibility with plastics.
[0033] Based on this, the present invention provides a grease application device, including a main body having a plurality of mutually independent grease reservoirs of the same depth. The main body is adapted to be configured to adhere to the sample, and the grease reservoirs expose the surface of the sample to be greased. After the main body is adhered to the sample, grease is filled into each of the grease reservoirs, and the grease adheres to the corresponding surface of the sample, thereby simplifying the grease application process. This advantage is particularly prominent in testing scenarios involving multiple grease samples. Because the depth of each grease reservoir is the same, after each reservoir is filled with grease, uniform adhesion of the grease to the surface of each sample can be achieved, and the control of the grease thickness is significantly improved, ensuring the consistency of the coating thickness. Due to the positioning of the grease reservoirs, the grease filled in each reservoir can be compacted, improving the adhesion between the grease and the sample and enhancing the bonding effect between them. Furthermore, since each grease reservoir is separate from the others, it can effectively prevent different greases from coming into contact with each other, thereby avoiding potential cross-contamination and providing more accurate and reliable experimental conditions for grease performance testing, ensuring the accuracy and repeatability of experimental results.

[0037] Please refer to Figure 1 , Figure 2 and Figure 3 This utility model provides a grease application device for applying grease to the surface of a sample 30, comprising: a main body 10 having a plurality of mutually separate grease reservoirs 101 of the same depth, the main body 10 being adapted to be configured to adhere to the sample 30, and the grease reservoirs 101 exposing the surface of the sample 30 to be greased.
[0038] After the main body 10 is attached to the sample 30, grease is filled into each of the grease reservoirs 101. The grease then adheres to the surface of the corresponding sample 30, simplifying the grease application process. This advantage is particularly pronounced in testing scenarios involving multiple grease samples. Since each grease reservoir 101 has the same depth, filling each reservoir with grease ensures uniform adhesion of the grease to the surface of each sample 30, significantly improving grease thickness control and ensuring consistent coating thickness. The positioning of the grease reservoirs 101 also compacts the grease within them, enhancing the adhesion between the grease and the sample 30 and strengthening their bonding effect. Furthermore, since each grease reservoir 101 is separate from the others, it can effectively prevent different greases from coming into contact with each other, thereby avoiding potential cross-contamination and providing more accurate and reliable experimental conditions for the performance testing of the grease, ensuring the accuracy and repeatability of the experimental results.
[0039] In this embodiment, the sample 30 is a plastic sample 30.
[0040] Please refer to Figure 4 In this embodiment, the grease application device further includes a scraper portion 20, which is adapted to be configured to scrape off the grease that overflows from the grease reservoir 101 and adheres to the surface of the main body 10. By scraping off the grease that overflows from the grease reservoir 101 and adheres to the surface of the main body 10 through the scraper portion 20, each grease reservoir 101 is just filled with grease, thereby further improving the consistency of the grease thickness applied to each of the sample parts 30.
[0041] Please refer to Figure 5 In this embodiment, the scraper portion 20 is slidably connected to the main body portion 10. This slidable connection satisfies the movement requirements of the scraper portion 20 during the scraping of excess grease, and also allows the scraper portion 20 and the main body portion 10 to be assembled into a single unit. After the scraper portion 20 and the main body portion 10 are assembled as a whole, the relative position and movement accuracy between them can be better controlled, thereby ensuring a uniform and consistent grease application thickness, meeting high-precision process requirements. Furthermore, the integrated assembly method makes the overall assembly more compact, facilitating carrying and storage, and improving the applicability and flexibility of the device.

[0043] In this embodiment, the slider 201 is a mushroom-shaped pin. A mushroom-shaped pin is a common mechanical connecting component, resembling a mushroom in shape with a larger head and a thinner stem. In achieving a sliding connection, the head of the mushroom-shaped pin acts as a limit, preventing the connecting component from detaching during sliding and ensuring connection stability. Secondly, its smooth surface and shape effectively reduce friction, making sliding smoother and reducing wear and energy loss. Furthermore, the mushroom-shaped pin has a simple structure, is easy to install and disassemble, and is easy to maintain and replace, saving time and costs. In a sliding connection, the mushroom-shaped pin can guide the component to move along a predetermined trajectory, preventing deviation from the track and improving motion accuracy.
[0044] Please continue to refer to this. Figure 2 and Figure 3 In this embodiment, a clamping part 301 is specially provided at the end of the sample piece 30. The clamping part 301 facilitates the clamping and fixing of the sample piece 30 by the clamping assembly (not shown). Simultaneously, each grease reservoir 101 has a contoured groove 103 at its end. The shape of the contoured groove 103 matches the clamping part 301 to accommodate it. By embedding the clamping part 301 into the contoured groove 103, precise positioning between the grease reservoir 101 and the sample piece 30 can be quickly achieved. The advantage of this design lies in its efficiency and accuracy. The correspondence between the clamping part 301 and the contoured groove 103 simplifies and speeds up the installation process, eliminating the need for complex alignment operations and greatly improving assembly efficiency. Furthermore, this structure ensures precise attachment between the grease reservoir 101 and the sample piece 30, with the grease reservoir 101 accurately fitting the sample piece 30, providing a reliable structural foundation for subsequent grease application operations.
[0045] Please continue to refer to this. Figure 4 and Figure 5 In this embodiment, the scraper portion 20 has a plurality of baffles 202, each baffle 202 corresponding to an adjacent grease reservoir 101. During the scraping of excess grease by the scraper portion 20, the grease overflowing from each grease reservoir 101 is confined between two adjacent baffles 202, thereby avoiding cross-contamination between different types of grease in adjacent grease reservoirs 101.
[0046] Please continue to refer to this. Figure 4 and Figure 5 In this embodiment, the scraper section 20 includes a handle 203. The handle 203 allows technicians to easily control the movement of the scraper section 20, ensuring a more convenient, flexible, and precise operation. The handle 203's design optimizes the user experience, improves work efficiency, and ensures operational stability.
[0047] Please continue to refer to this. Figure 5 In this embodiment, the main body 10 has an arc-shaped structure to adapt to the surface of the clamp assembly used to fix the sample 30. Correspondingly, the surfaces of the scraper 20 that contact the main body 10 to scrape off excess grease, and the surfaces of the baffle 202 that contact the main body 10, are also designed as contoured arc surfaces to better achieve a fit with the main body 10, thereby improving the scraping effect on excess grease.
[0048] Please continue to refer to this. Figure 1 , Figure 2 and Figure 5 In this embodiment, the main body 10 has 5 to 8 grease reservoirs 101, preferably 6.
