Description

Technical Field

[0001] The utility model relates to the technical field of trolley case testing, in particular to a trolley case compression testing device. Background Art

[0002] A trolley case refers to a suitcase with a trolley and wheels. It is widely used because of its convenience. At the same time, trolley cases are also divided into single-tube trolleys and double-tube trolleys because of the trolley on the case. The tube of the trolley is also divided into square tubes and round tubes, which is convenient for dragging when walking and greatly reduces the burden. Trolley cases can be carried or dragged. The wheels of the trolley cases we usually use are basically located at the bottom of the case, but modern people have designed a new form of trolley case, which is designed into a cylindrical shape, and the wheels are completely wrapped outside the case. This roller design allows this trolley case to better adapt to different terrains, such as directly pulling the case to go up and down stairs easily. In 2012, the main materials are cloth boxes, ABS hard boxes, leather boxes, PC, etc., and the usability is divided into three categories: fixed wheels, universal wheels, and the latest detachable universal wheel trolley cases.

[0003] As disclosed in the authorization announcement number CN218847611U, a fatigue test device for a trolley case is disclosed, which belongs to the technical field of trolley case testing equipment. It is composed of a bottom plate, a frame, a telescopic mechanism, a limiting mechanism, a driving motor, a tension belt and a winding shaft. The bottom plate is provided with a limiting mechanism, the bottom plate outside the limiting mechanism is provided with a frame, the top of the frame is provided with a telescopic mechanism corresponding to the limiting mechanism, and one side of the frame is symmetrically provided with a tension belt through a mounting rod. Through the cooperation of a push block, a pedal, a tooth plate and a bottom plate, it is convenient for the staff to slide the push block with their feet and adjust it according to the model of the trolley case. The push block drives the pressing plate to move, and cooperates with the positioning plate to press the trolley case against the limit position, and the operation is simple; through the cooperation of a driving motor, a winding shaft and a tension belt, the tension belt is wound on the winding shaft and gradually tightened, thereby pressing down the top of the trolley case to prevent the trolley case from moving up during the test, and is suitable for trolley cases of different models. However, it is not convenient to move and fix the trolley case during use. For this purpose, we propose a trolley case compression test device, which is easy to move and convenient for fixing the trolley case. Utility Model Content
