Description

Technical Field

[0001] The utility model relates to the technical field of luggage wheel testing, in particular to a wear resistance test device for luggage wheels. Background Art

[0002] Luggage is a general term for bags, which are used to hold various items, including general shopping bags, handbags, clutch bags, wallets, backpacks, single-shoulder bags, messenger bags, hip bags, and various rolling suitcases. When manufacturing luggage with wheels, wear resistance tests need to be conducted on the luggage wheels to know the wear resistance of the luggage wheels and the quality inspection problems of the luggage wheels through data.

[0003] The existing wear resistance test device for luggage wheels, such as a wear resistance test device for luggage wheels described in the publication number: CN220339954U, only has one type of test wheel. In actual situations, luggage wheels roll on two types of roads, namely smooth roads and rough roads. Testing the wear resistance under one roughness level is not comprehensive. Summary of the Invention

[0004] The technical problem to be solved by the utility model is aimed at the deficiencies of the above-mentioned prior art.

[0005] To provide a wear resistance test device for luggage wheels, which can simultaneously test the wear resistance of luggage wheels on roads with different roughness levels.

[0006] To achieve the above object, the utility model provides the following technical solution: A wear resistance test device for luggage wheels, including a base, characterized in that: One grinding wheel simulating a rough road surface and one steel wheel simulating a smooth road surface are symmetrically arranged side by side on one side above the base. The grinding wheel and the steel wheel have the same diameter. The grinding wheel and the steel wheel are both provided with wheel seats, and the grinding wheel and the steel wheel are both rotatably connected to the wheel seats. The wheel seats are fixedly connected to the base. The highest points of the grinding wheel and the steel wheel are at the same height. A back plate bracket is provided behind the base, and a lifting cylinder is connected to the back plate bracket. The output end of the lifting cylinder is provided with a mounting plate. The mounting plate is symmetrically provided with mounting positions for mounting the wheels to be tested. The two wheels to be tested are respectively arranged in the corresponding mounting positions, and the wheels to be tested are respectively arranged above the grinding wheel and the steel wheel. The lifting cylinder drives the mounting plate to lift and lower so that the wheels to be tested are in contact with the corresponding grinding wheel and the steel wheel above and can apply an adjustable pressure. The grinding wheel and the steel wheel are provided with drive motors for driving them to rotate.

[0007] The utility model with the above characteristics: Simultaneously provided with a grinding wheel simulating a rough road surface and a steel wheel simulating a smooth road surface, which can simultaneously test the wear resistance of luggage wheels on different rough road surfaces. At the same time, one lifting cylinder drives the two wheels to be tested to move downward to simulate the pressure generated by the same weight for the two wheels to be tested.

[0008] A further arrangement of the utility model is: a first synchronous wheel is linked to the output end of the driving motor, a second synchronous wheel is coaxially arranged outside the grinding wheel extending to the wheel seat, a third synchronous wheel is coaxially arranged outside the wheel seat, a fourth synchronous wheel capable of rotating is provided on the back plate above the driving motor, the first synchronous wheel, the second synchronous wheel, the third synchronous wheel and the fourth synchronous wheel are arranged side by side, the first synchronous wheel, the second synchronous wheel, the third synchronous wheel and the fourth synchronous wheel have the same diameter, and a synchronous belt is connected between the first synchronous wheel, the second synchronous wheel, the third synchronous wheel and the fourth synchronous wheel.

[0009] The utility model with the above characteristics: a driving motor drives the grinding wheel and the steel wheel to rotate synchronously, so that the rotation speed and the number of rotations of the grinding wheel and the steel wheel are the same.

[0010] A further configuration of the utility model is that a bottom plate is provided below the base, and a pressure sensor is provided at the center connected between the bottom plate and the base.

[0011] The utility model with the above characteristics: the pressure sensor can determine the value generated by the lifting cylinder, which is convenient for adjusting the pressure applied by the lifting flagpole to simulate the pressure generated by different weights on the test wheel.

[0012] The utility model has the beneficial effect that the wear resistance of luggage wheels on roads with different roughness levels can be tested simultaneously, so that the test results are more comprehensive.
