Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a test device for the wear resistance of bag bottom wheels. Background Technology

[0002] Bags and luggage are a general term for various bags used to carry things. When producing wheeled bags and luggage, wear resistance tests are required on the wheels. This data allows us to determine the wear resistance of the wheels and assess their quality. A search revealed Chinese patent publication number CN220339954U, which discloses a wear resistance testing device for bag and luggage wheels. The device includes a base, a hydraulic cylinder seat fixedly mounted on the top of the base's side plate, and a test wheel fixedly connected to the outer end of the hydraulic cylinder seat's output shaft on the top side of the base. A drive motor is mounted on the top surface of the base, and the output shaft of the drive motor passes through a slide and is fixedly fitted with a rotating shaft located on the top side of the slide, with the test wheel mounted on the rotating shaft. A support column fixedly mounted on the top of the base, located outside the drive motor, is movably fitted with a bag wheel located outside the test wheel.

[0003] While the above-mentioned technical solution can enable the wheel to rub against the bag wheel and calculate the actual travel distance of the bag wheel based on the number of rotations of the test wheel, thus facilitating the calculation of the bag wheel's wear resistance, it cannot accurately monitor various data during use. Furthermore, the different inner diameters of different types of bag wheels make it inconvenient to limit their movement, thus affecting the practicality of the device. In addition, it needs to be removed and reinstalled after each test, which is cumbersome and reduces work efficiency. Utility Model Content
