Description

Technical Field

[0001] This utility model belongs to the field of coating hardness testing technology, specifically referring to a device for testing the hardness of water-based coating films. Background Technology

[0002] Water-based coatings use water as a solvent or dispersion medium and are a relatively new type of coating on the market. Water-based coatings use water-soluble resins as film-forming agents, with polyvinyl alcohol and its various modified forms being representative. Other types include water-soluble alkyd resins, water-soluble epoxy resins, and inorganic polymer water-based resins. Hardness is one of the most important physical properties of a coating. Coating hardness reflects its ability to resist constant indentation, scratching, tangential stress, and penetration from a hard object. Different methods for testing material hardness will yield different results because each method targets different quantities of the material. Each method has its own metric that can standardize the hardness measured by different methods, but results obtained using a single method are comparable.

[0003] The pencil hardness test is a commonly used method for testing the hardness of coatings. The pencil hardness test focuses on reflecting the coating's resistance to indentation, scratches, and abrasions. However, most existing testing methods involve manually scratching the surface of the coating with a hand-held hardness test pencil. This manual method is prone to variations in pressure applied by the user, and requires changing pencils of different hardnesses for variable testing, making it cumbersome and inconvenient, and potentially affecting the accuracy of the results. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a water-based coating film hardness testing device, which effectively solves the above problems.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes a water-based coating film hardness testing device, including a test platform, a flat support cover, a hardness testing device, and a drive swing rod. The flat support cover has sliders connected to both sides via horizontal plates. The sliders are connected to slide rails, which are located on both sides of the test platform. Multiple hardness testing devices are distributed within the flat support cover. Each hardness testing device is rotatably and elastically mounted on a support shaft, which is fixedly connected to the inner wall of the flat support cover. An elastic buckle is provided at the bottom of each hardness testing device, into which a hardness testing pen is inserted. A sealing component is movably mounted on one side wall of the hardness testing device. The sealing component includes a sealing plate, a moving part, and a traction hook. The moving part is movably mounted on a connecting part, which is fixedly mounted on one side of the hardness testing device. One end of the moving part is fixedly connected to the sealing plate, and the other end is fixedly connected to the traction hook. The drive swing rod is rotatably mounted on the flat support cover.

[0006] Furthermore, the sealing plate is movably positioned on one side of the elastic buckle and movably abuts against the hardness testing pen, and the traction hook can be connected to the drive swing arm.

[0007] Furthermore, the two ends of the drive swing arm are connected to the support swing arm, and the drive swing arm is rotatably connected to both sides of the flat support cover through the support swing arm. The rotation swing axis of the drive swing arm is coaxial with the support shaft.

[0008] Furthermore, the bottom of the elastic buckle has a strip-shaped opening, and the inner wall of the elastic buckle is bonded with an elastic pad.

[0009] Furthermore, the hardness testing device is equipped with a torsion spring structure, which allows the hardness testing device to rotate elastically, thereby controlling the end of the hardness testing pen to face downwards and adhere to the surface of the testing platform.

[0010] Furthermore, limit posts are provided on both sides of the flat support cover, and the limit posts are located on one side of the support swing rod.

[0011] Furthermore, a protrusion is provided at one end of the surface of the test stand, and support legs are provided on both sides of the test stand.

[0012] The beneficial effects of this utility model using the above structure are as follows: The hardness testing pen is inserted into the hardness testing device using an elastic buckle, making disassembly convenient. The movable sealing component effectively seals and fixes one end of the hardness testing pen, ensuring stability during sliding and preventing it from falling off. Simultaneously, the hardness testing device uses a torsion spring structure that can be elastically rotated on the support shaft, allowing the testing end of the hardness testing pen to always remain in contact with the test platform surface. Furthermore, the flat-push support cover can simultaneously support multiple hardness testing devices, enabling simultaneous variable testing with hardness testing pens of various hardnesses, greatly improving testing efficiency and ease of use. The rotatable support swing arm can press down on the traction hook by rotating, allowing multiple hardness testing devices to rotate synchronously to lift the hardness testing pen, facilitating device reset.

Multiple hardness testing devices 3 are provided, distributed within the flat support cover 2. Each hardness testing device 3 is elastically rotatably mounted on a support shaft 21, which is fixed to the inner wall of the flat support cover 2. The bottom of the hardness testing device 3 is provided with an elastic buckle 11, and a hardness testing pen 6 is inserted into the elastic buckle 11. A sealing component 5 is movably provided on one side wall of the hardness testing device 3. The sealing component 5 includes a sealing plate 7, a moving part 8 and a traction hook 9. The moving part 8 is movably inserted into the connecting part 12, and the connecting part 12 is fixedly provided on one side of the hardness testing device 3.

[0024] In one embodiment of this utility model, the sealing plate 7 is movably disposed on one side of the elastic buckle 11 and movably abuts against the hardness testing pen 6, and the traction hook 9 can be hooked to the drive swing rod 13.

[0025] In one embodiment of the present invention, the two ends of the drive swing rod 13 are connected to the support swing rod 14. The drive swing rod 13 is rotatably connected to both sides of the flat support cover 2 through the support swing rod 14.

[0026] In one embodiment of the present invention, the bottom of the elastic buckle 11 is provided with a strip-shaped opening, and the inner wall of the elastic buckle 11 is bonded with an elastic pad 10.

[0027] In one embodiment of this utility model, the hardness testing device 3 is provided with a torsion spring structure, which allows the hardness testing device 3 to rotate elastically, thereby controlling the end of the hardness testing pen 6 to face downward and adhere to the surface of the test platform 1.

Then, the moving part 8 slides up and down the connecting part 12 until the sealing plate 7 abuts against one end of the hardness testing pen 6 mounted on the elastic clip 11. At this time, the hardness testing device 3, through its internal torsion... The spring structure is rotatably mounted on the support shaft 21, allowing the testing end of the hardness testing pen 6 mounted on it to always be in contact with the surface of the test bench 1. After the setup is complete, the relevant personnel can manually push the drive swing rod 13 to rotate it until the support swing rod 14 abuts against the limit post 18. Then, by continuing to apply force, the flat support cover 2 can slide on the slide rail 17 through the sliders 16 on both sides, controlling multiple hardness testing pens 6 to slide from one end of the surface of the board to be tested to the other end. This enables hardness testing of multiple hardness specifications of hardness testing pens 6 to be performed simultaneously on the surface of the board to be tested, making the operation more stable and ensuring the testing accuracy.
