[0016] See Figure 1-3The figure shows a luggage inspection device comprising a bracket 10 and a movable assembly 20. A limit plate 11 is provided on the bracket 10, and a rack channel 111 is defined in the limit plate 11. The movable assembly 20 comprises a vertically arranged rack 21, a half gear 22, and a drive motor 24. The half gear 22 meshes with the rack 21. A limit member 12 is provided at the upper end of the rack 21. The rack 21 passes through the rack channel 111, and the limit member 12 is larger than the rack channel 111. The drive motor 24 is fixed to the bracket via a support plate (not shown in the figure). The drive motor 24 rotates the half gear 22, thereby driving the rack 21 upward. When and only when the rack 21 reaches the toothless area of the half gear 22, the rack 21 falls under the action of gravity. A hook 23 is fixed to the lower end of the rack 21. The luggage handle to be tested is hung on the hook 23. Specifically, a certain amount of weight is added into the suitcase to simulate the state of the suitcase being filled with items, the handle of the suitcase is hung on the hook, and the drive motor is started. The half gear is engaged with the rack, and the drive motor drives the half gear to rotate. The toothed part of the half gear drives the rack to move upward, thereby driving the suitcase to move upward to a certain height; when and only when the half gear rotates to the toothless part, the half gear and the rack are no longer engaged. At this time, the rack will fall together with the suitcase under the action of gravity until the limit piece contacts the limit plate, and the rack stops moving downward. At this time, the handle of the suitcase is subjected to the greatest impact. This cycle is repeated multiple times according to the design requirements. By checking whether the handle is broken or damaged, and the connection condition of the handle and the suitcase body, it can be determined whether the strength of the suitcase handle meets the design requirements.
[0017] In addition, in order to ensure the smooth movement of the rack, see Figure 3 As shown, this embodiment preferably also includes a stabilizing assembly 30, which includes side rollers 31 that contact the side surfaces of the rack 21 and back rollers 32 that contact the back surface away from the teeth. Both the side rollers 31 and back rollers 32 are in contact with the rack 21 or have a set clearance. Preferably, two sets of stabilizing assemblies 30 are provided, symmetrically positioned above and below the half gear 22. Thus, the side rollers 31 and back rollers 32 support and support three sides of the rack 32, while the third side is limited by the half gear 31, thereby ensuring smooth and stable operation of the rack. Among them, the side rollers 31 and the back rollers 32 are preferably bearings, and the bearings are connected to the bracket 10 through a rotating shaft. A receiving groove is provided at a corresponding position on the bracket 10, and the bearing is located in the receiving groove. The rotating shaft can pass through the inner hole of the bearing located in the receiving groove through the shaft hole provided on the bracket 10, and the other end is inserted into the shaft hole on the bracket; this can facilitate the maintenance of the bearing in the later stage, and the bearing can be replaced by only pulling out the rotating shaft; of course, it should be noted that a rotating shaft limiting part is also provided, and a top screw hole can be provided on the side of the shaft hole, and the top screw can be screwed into the top screw hole to tighten it on the rotating shaft to achieve the limitation of the rotating shaft.
