Description

Technical Field

[0001] The utility model belongs to the technical field of glove detection, and in particular relates to a glove durability testing device. Background Art

[0002] Protective gloves are protective products that prevent physical, chemical, biological and other external factors from harming the hands of workers during labor, and are widely used in many fields. In daily work environments, workers often face situations such as sharp tool injuries, injuries from rotating mechanical equipment parts, contact with corrosive chemicals, and injuries from high or low temperature objects. At this time, workers need to wear protective gloves with certain wear resistance to protect their hands from injury. In order to ensure the wear resistance of protective gloves, Martindale abrasion tester has been used to test the wear resistance of protective gloves. Although the wear resistance of the palm can be guaranteed, due to the high frequency of use of the thumb, index finger and middle finger of the protective gloves, the phenomenon of wear and tear is more serious. Therefore, the wear resistance of the fingers will also affect the overall wear resistance of the protective gloves. At present, the Martindale abrasion tester can only test palm samples with a larger area, but it is difficult to test finger samples with a smaller area.

[0003] In the prior art, there are studies on the difficulty of Martindale abrasion tester to perform wear resistance test on fingers with a small area, such as patent application CN110954431A-A method and device for testing wear resistance of finger contact surface of protective gloves, CN217738824U-A wear resistance test device for protective gloves, etc., which use a grinding head or a grinding wheel to rub the fingers with a small area, solving the problem that the current Martindale abrasion tester is difficult to perform wear resistance test on fingers with a small area. However, the existing wear resistance test device can only perform wear resistance test on fingers, but it is difficult to effectively test the palm, and the test accuracy is also difficult to be effectively controlled, which seriously affects the overall durability of the protective gloves. Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

Since the driven wheel 701 is hinged to the end of the adjusting shaft 602 through the support frame 702 and the support frame 702 is clamped with a balance arm 8, the driven wheel 701 will move horizontally on the slide rail 15 under the combined action of the rotation of the adjusting shaft 602 and the horizontal direction of the balance arm 8. At the same time, the balance arm 8 will also move synchronously between the stop seat 23 and the limit stop seat 17 with the horizontal movement of the driven wheel 701, thereby driving the glove sample 11 to repeatedly rub against the test plate 2, so as to realize the durability test of the glove sample 11; after the durability test is completed, the motor 4 is turned off through the control box 19, and the balance arm 8 will stop moving. Then the clamping rod 1002 is removed from the jacket 1001 through the adjusting nut 21, and finally the tested glove sample 11 is removed.
