Description
Technical Field
[0001] The utility model relates to the technical field of luggage wheel detection, in particular to a device for luggage wheel detection. Background Art
[0002] Luggage is a general term for bags, which is a general term for various bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags and various trolley cases. Before the luggage is produced and put into use, the coaxiality and luggage wheels need to be tested to avoid large errors in the coaxiality of the luggage wheels causing excessive shaking during the movement of the luggage and damage to the luggage wheels when driving on uneven roads.
[0003] In traditional technology, the inspection of luggage wheels can only be carried out in a single test, and the wheelbase and wheel strength of the luggage wheels cannot be tested at the same time, which greatly reduces the inspection efficiency and increases the inspection cost. At the same time, the wheelbase inspection of luggage wheels in traditional technology is relatively simple and cannot be accurately measured, which increases the error of the measurement results, and the luggage produced still has the problem of movement and shaking.
[0004] During use, it was found that traditional technology can often only test a single performance of luggage wheels, such as only testing coaxiality or firmness, but cannot simultaneously test multiple key indicators such as coaxial distance and firmness. Due to the single detection function and lack of automated integration, traditional detection methods require multiple repeated operations to complete the detection of different items, which greatly reduces the detection efficiency and increases the production cycle and cost. The coaxial distance detection means of luggage wheels in traditional technology are relatively simple, and lack high-precision measuring equipment and scientific detection methods, resulting in large errors in the measurement results. This inaccurate measurement not only cannot accurately reflect the actual performance of luggage wheels, but may also mislead production decisions, causing the produced luggage to move and shake during use.
