Description

Technical Field

[0001] This utility model belongs to the field of luggage production technology, specifically relating to a luggage testing device. Background Technology

[0002] Luggage consists of multiple components, including the main body, wheels, and handle. Since luggage is often used in complex conditions, including on asphalt, cobblestone streets, and even when dragged up and down stairs, the wheels may accidentally hit the steps, causing impact. Therefore, after assembly, luggage needs to undergo simulated working conditions testing to ensure it functions properly under heavy loads and extreme conditions, without breaking or being damaged. This ensures consistent quality across batches and meets design requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a bag and luggage testing device, which aims to test the strength, quality and durability of bags and luggage after production, so as to determine whether the quality of the bags and luggage meets the design requirements.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] A luggage inspection device includes a circulating conveyor assembly. A simulation component is mounted on the conveyor belt of the circulating conveyor assembly. The simulation component includes multiple simulation blocks fixedly connected side-by-side to the outer surface of the conveyor belt. It also includes a fixed frame located above the circulating conveyor assembly, with hooks mounted on the frame. A suitcase's pull rod is connected to the hooks via a connector, and the suitcase's wheels can contact the surface of the conveyor belt. The conveyor belt drives the simulation blocks to move, and the simulation blocks contact the suitcase, pushing it upwards. At the end of the last simulation block, the suitcase begins to fall onto the conveyor belt under gravity.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: a metal plate is fixed on the conveyor belt, the metal plate is located at the rear end of the simulation block, and when the suitcase falls, it falls exactly onto the metal plate.

[0007] Based on the above solution and as a preferred solution: a weight of a set weight is placed on the pull handle of the suitcase.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the weight is a sandbag.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: multiple weight reduction holes are formed on the simulation block along its length direction.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the simulation block is made of plastic.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the connecting member is a traction belt.

[0012] The outstanding and beneficial technical effects of this invention compared to the prior art are as follows: the conveyor belt drives the simulated block to move, thereby pushing the suitcase hanging obliquely on the fixed frame upwards. After the suitcase swings upwards to a certain height, as the simulated block continues to move to its end, the suitcase loses the support of the simulated block and begins to fall rapidly onto the conveyor belt under the action of gravity. In order to further simulate the effect of a real road surface and avoid the impact of the conveyor belt's cushioning on the suitcase's test results, a metal plate is set on the conveyor belt. When the suitcase falls, it directly hits the metal plate, thereby approximating the impact of a real road surface as closely as possible and obtaining more realistic test results.

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the given embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0018] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0019] See details Figure 1-3 As shown, this application discloses a bag and luggage testing device, including a circulating conveyor assembly 20. A simulation assembly 30 is mounted on the conveyor belt 22 of the circulating conveyor assembly 20. The simulation assembly 30 includes multiple simulation blocks 31 fixedly connected side-by-side to the outer surface of the conveyor belt 22. It also includes a fixing frame 23 located above the circulating conveyor assembly 20. A hook 24 is mounted on the fixing frame 23. The pull rod 11 of the suitcase 10 is connected to the hook 24 via a traction belt 25, and the rollers 13 of the suitcase 10 can contact the surface of the conveyor belt 22. The fixing frame 23 can be fixed to a wall or a machine frame using expansion bolts to provide sufficient support for the suitcase after it is hung on the hook and during subsequent testing. Specifically, the circulating conveyor assembly 20 includes a drive motor 23, a transmission assembly, multiple transmission rollers 21, and a conveyor belt 22. The conveyor belt 22 surrounds the transmission rollers 21. The transmission assembly includes a driving synchronous pulley 223, a synchronous belt 222, and a driven synchronous pulley 221. The drive motor 23 drives the transmission rollers 21 to rotate via the transmission assembly. The transmission rollers 21 drive the conveyor belt 22 to move in a specific direction through friction, thereby causing the simulated blocks 31 on the conveyor belt 22 to move in a specific direction at a certain speed. According to the structure of the conveyor belt 22, the simulated blocks 31 are circulated along the conveyor belt. In other words, at regular intervals, the simulated block 31 contacts the suitcase 10. After contact, the simulated block 31 pushes the suitcase 10. Due to the constraint of the connecting piece 25, hook, and fixing frame, the suitcase's pull rod swings upward. At the end of the last simulated block 31, the suitcase 10 detaches from the support of the simulated block and begins to fall onto the conveyor belt 22 under gravity. This simulates the impact of the suitcase falling from a certain height, thereby testing the reliability and strength of the suitcase's pull rod, wheels, and main structure. Specifically, the number of times the simulated block contacts the suitcase, i.e., the number of impacts the suitcase experiences, is controlled according to the testing needs to determine whether the structural strength of the suitcase meets the requirements. It should be noted that in this embodiment, multiple weight-reducing holes are formed along the length of the simulated block 31 to reduce its weight. Furthermore, it is preferable that the simulated block 31 is made of plastic to combine the advantages of strength and weight.

[0020] To further simulate the effect of a real road surface and avoid the impact of the conveyor belt's cushioning on the luggage inspection results, this embodiment preferably has a metal plate 32 fixed on the conveyor belt 22. The metal plate 32 is located at the rear end of the simulation block 31, so that when the luggage 10 falls, it lands directly on the metal plate 32. The luggage falls directly onto the metal plate, thereby simulating the impact of a real road surface as much as possible and obtaining more realistic inspection results. The metal plate 32 is fixed to the conveyor belt by screws 331 that pass through the conveyor belt and are screwed into the threaded holes at the bottom of the metal plate 32. Due to the small fixed connection area and the large diameter of the conveyor roller, and by reasonably selecting the size of the metal plate 32, the metal plate 32 can move smoothly when it moves to the curved position of the conveyor roller without interfering with the conveyor roller. Similarly, the simulation block 31 is also fixedly installed on the conveyor belt using the same connection structure. Similarly, by reasonably selecting the size of the simulation block 31, it can also smoothly follow the synchronous belt. In this embodiment, three simulation blocks 31 are preferably set with a gap between them to simulate the dragging state of the paved road surface.

[0021] Furthermore, to more realistically simulate the use of a suitcase, in this embodiment, it is preferable to place a weight 40 of a predetermined weight on the handle 11 of the suitcase 10. Of course, depending on design and testing needs, a weight can also be added inside the suitcase to simulate a suitcase filled with items. Sandbags are a preferred type of weight 40.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
