Description

Technical Field

[0001] This utility model relates to the field of labor protection product testing technology, specifically a device for testing the abrasion resistance of protective gloves. Background Technology

[0002] Protective gloves are protective equipment used to protect hands from physical, chemical, or biological hazards. Their main function is to prevent hand injuries, and they are suitable for various work and life scenarios. Work gloves typically have anti-slip particles on the palm or are made of high-abrasion-resistant materials such as rubber or leather. After these gloves are manufactured, their abrasion resistance is typically tested manually by rubbing the gloves against a standard abrasive or grinding wheel, and the data is recorded to determine the gloves' abrasion resistance.

[0003] However, when conducting multi-sample testing, it is difficult to accurately control the frictional pressure between the grinding wheel and the glove every time by manual operation, resulting in inconsistent test pressure and reducing the accuracy of test results.

[0004] Therefore, it is necessary to provide a new device for testing the abrasion resistance of protective gloves to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a protective glove abrasion resistance testing device that can ensure uniformity of test pressure, improve the accuracy of test results, and flexibly adjust the test pressure according to different gloves.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the protective glove abrasion resistance testing device provided by this utility model; Figure 2 This is a schematic diagram of the structural connection on the positioning folding platform in this utility model; Figure 3 This is an assembly diagram of the first and second slanted frames in this utility model; Figure 4This is a front view schematic diagram of the positioning folding table structure in this utility model. The protective glove abrasion resistance testing device includes: a testing platform 1, a positioning folding table 13 fixedly installed on the top of the testing platform 1, a recessed groove 20 formed on the top of the positioning folding table 13, and a single-axis cylinder 14 fixedly installed on the top of the positioning folding table 13, the output shaft of which passes through the top of the positioning folding table 13 and is slidably connected to the top of the positioning folding table 13. A connecting piece 15 is fixedly installed on the output shaft of the single-axis cylinder 14, and a friction assembly is fixedly installed at the bottom of the connecting piece 15. This friction assembly is a common component on the market, including a drive motor 16, which is fixedly installed at the bottom of the connecting piece 15. A grinding wheel 17 is fixedly installed on the output shaft of the drive motor 16 by bolts, which facilitates the replacement of grinding wheels 17 of different diameters for different sizes of gloves. A grinding wheel 17 is rotatably installed on the bottom inner wall of the recessed groove 20. Adjusting screw 21 has a height limiting plate 22 threaded on it. The height of the height limiting plate 22 is the same as the depth of the sink groove 20. This ensures that in the initial state, the height limiting plate 22 can enter the sink groove 20, and its top end face is flush with the top end face of the positioning folding table 13, improving the accuracy of test pressure adjustment. A fixing folding rod 18 is fixedly installed on the top of the connecting plate 15. The fixing folding rod 18 passes through the positioning folding table 13 and is slidably connected to the positioning folding table 13. An abutment block 19 is fixedly installed on the end of the fixing folding rod 18 above the positioning folding table 13. The abutment block 19 is located above the height limiting plate 22, so that when the output shaft of the single-axis cylinder 14 extends, it can be limited by the height limiting plate 22, so that the grinding wheel 17 has a final lowering position, and also ensures that each wear resistance test can have the same friction pressure.

[0022] A fixing mechanism is provided on the testing platform 1 to secure the protective gloves. This fixing mechanism includes two support slide bars 2, which are respectively fixedly installed on both sides of the testing platform 1. A first adjusting block 3 and a second adjusting block 8 are slidably mounted on each of the two support slide bars 2. The two first adjusting blocks 3 and the two second adjusting blocks 8 are symmetrically arranged with the testing platform 1 as the center. A first slanted frame 4 is fixedly installed on the top of the two first adjusting blocks 3. A first dual-axis cylinder 5 is fixedly installed on the top of the first slanted frame 4, and its output shaft extends into the first slanted frame 4 and slidably connects to the top of the first slanted frame 4. The output shaft of the first dual-axis cylinder 5 is fixedly mounted on... A first connecting crank arm 6 is fixedly installed, and a palm heel pressure plate 7 is fixedly installed at the bottom of the first connecting crank arm 6. A second girder 9 is fixedly installed on the top of the two second adjusting blocks 8. A second dual-axis cylinder 10 is fixedly installed on the top of the second girder 9, and its output shaft extends into the second girder 9 and slides to connect with the top of the second girder 9. A second connecting crank arm 11 is fixedly installed on the output shaft of the second dual-axis cylinder 10, and a finger pressure plate 12 is fixedly installed at the bottom of the second connecting crank arm 11. The palm heel pressure plate 7 and the finger pressure plate 12 can press the glove from both ends, thereby stably performing friction tests on the palm area.

[0023] In the above method, in order to fix the first girder 4 and the second girder 9 in their adjusted positions, a first fastening screw is threaded on one of the first adjusting blocks 3, the end of which abuts against the corresponding support slide bar 2, and a second fastening screw is threaded on one of the second adjusting blocks 8, the end of which abuts against the corresponding support slide bar 2.

[0024] In this method, in order to accurately adjust the friction pressure, a measuring scale 23 is fixedly installed on the top of the positioning folding table 13. A guide plate is fixedly installed on the side of the height limiting plate 22 away from the single-axis cylinder 14. The top end face of the guide plate is flush with the top end face of the height limiting plate 22, and the guide plate is compatible with the measuring scale 23. In addition, a limit rod is fixedly installed on the bottom inner wall of the recessed groove 20. The limit rod passes through the height limiting plate 22 and is slidably connected to it. This ensures that when the adjusting screw 21 is rotated, the height limiting plate 22 will not rotate with it, so as to form a stable linear lifting and lowering. In addition, a third fastening screw is threaded on one side of the height limiting plate 22, and its end abuts against the limit rod, thereby forming a positioning effect.

[0025] In this method, the distance between the grinding wheel 17 and the top end face of the detection platform 1 is the same as the distance between the contact block 19 and the top end face of the positioning folding table 13. This allows for intuitive adjustment of the distance between the grinding wheel 17 and the glove, simply by reading the pointing value of the guide plate on the measuring scale 23.

[0026] The working principle of the protective glove abrasion resistance testing device provided by this utility model is as follows:

[0027] When it is necessary to test the abrasion resistance of protective gloves, first change the grinding wheel 17 to the corresponding diameter according to the size of the glove to be tested. Then place the glove on the testing platform 1 with the palm part below the grinding wheel 17. Then adjust the palm heel pressure plate 7 according to the position of the palm heel of the glove. When adjusting, tighten the first tightening screw to separate it from the corresponding support slide bar 2. Then move the first adjusting block 3 horizontally to adjust the position of the palm heel pressure plate 7 until it is adjusted to be above the palm heel of the glove. Then tighten the first tightening screw again. Then start the first dual-axis cylinder 5. Its output shaft extends and lowers the palm heel pressure plate 7, finally pressing down the palm heel of the protective glove.

[0028] Next, adjust the horizontal position of the finger pressure plate 12 according to the position of the finger part of the glove. When adjusting, first rotate the second fastening screw in the opposite direction to separate it from the corresponding support slide bar 2. Then, move the second adjusting block 8 horizontally. After the finger pressure plate 12 moves to the designated position, tighten the second fastening screw again. Then, start the output shaft of the second dual-axis cylinder 10 to extend and use the finger pressure plate 12 to press the fingers of the glove.

[0029] Then, adjust the lowest position of the grinding wheel 17 as required, i.e., the friction pressure between it and the glove. When adjusting, first rotate the third fastening screw in the opposite direction to separate it from the limit rod, then rotate the adjusting screw 21, and the height limit plate 22 descends. At this time, observe the positional relationship between the guide plate and the measuring ruler 23. After moving to the specified height, tighten the third fastening screw again. Then, start the drive motor 16 to drive the grinding wheel 17 to rotate, and then start the output shaft of the single-axis cylinder 14 to extend. The drive motor 16 drives the grinding wheel 17 to descend. When the contact block 19 contacts the height limit plate 22, the grinding wheel 17 will no longer descend, and at this time, there is a certain friction pressure between the grinding wheel 17 and the glove. At this time, the rotating grinding wheel 17 will rub against the glove, thus forming a friction detection.

[0030] Compared with related technologies, the protective glove abrasion resistance testing device provided by this utility model has the following advantages:

[0031] This invention provides a device for testing the abrasion resistance of protective gloves. Through the cooperation of the adjusting screw 21 and the height limiting plate 22, and with the assistance of the measuring scale 23, the height of the grinding wheel 17 can be adjusted according to different gloves or different friction pressure parameters. This effectively ensures that each friction test can be carried out under the same friction pressure, improving the accuracy of the test results. Furthermore, the movable and adjustable first adjusting block 3 and second adjusting block 8 can fix and test gloves of different sizes, making it widely applicable.
