Description

Technical Field

[0001] This utility model relates to the field of suitcase technology, specifically to an EPP suitcase with a classified storage function. Background Technology

[0002] Current suitcases have limitations in storage functionality, often failing to meet users' needs for categorizing and storing different items. This is especially true in scenarios such as outdoor adventures and professional repairs, where users need to quickly and accurately find the items they require. The shortcomings of traditional suitcases in terms of storage often affect efficiency. Therefore, developing a suitcase with categorized storage functionality is particularly important.

[0003] Referring to the CN221368445U, an EPP suitcase with categorized storage is described. It includes a suitcase body, an inner wall of which is provided with a sliding limit rod, which is slidably connected to the suitcase body. A sealing plate is installed at the upper end of the sliding limit rod, and a handle is installed inside a groove at the upper end of the sealing plate. A fixed tray is installed at the end of the sliding limit rod, and a fixing block is installed at the lower end of the fixed tray. A limit plate is installed on the surface of the upper end of the sliding limit rod of the fixed tray, and a limiter is installed at the upper end of the limit plate. The expandable tray, compared to existing ordinary EPP foam boxes, allows for the loading of different items through the design of the expandable tray and limiting plates. By adjusting the height of each expandable tray without limiting plates, the expandable capacity of the suitcase can be improved, and items can be quickly retrieved when needed, thus improving retrieval efficiency. As mentioned above, although this suitcase can be used well, it is usually not convenient to adjust the size of the storage cavity, making it difficult to adjust according to the specifications of tools, which affects the convenience of tool storage and often troubles users.

[0014] (1) By setting two partitions, the inner side of the EPP main box is divided into three storage cavities. Then, by rotating the handle, the threaded cylinders at both ends of the handle slide towards each other on the outer walls of the two threaded rods to adjust the distance between the two partitions. The size of the three storage cavities can be adjusted as needed according to the specifications of the storage tools, thereby improving the convenience of storing tools in the suitcase.

[0015] (2) By wrapping the label tape around the outer walls of both sides of the EPP main body and the EPP auxiliary body, then inserting one end of the label tape into the buckle frame and passing the buckle rod through a buckle groove, the two label tapes are fitted onto the outer walls of the EPP main body and the EPP auxiliary body, which makes it easier for users to distinguish the information of the suitcase according to the label tape, thereby reducing the phenomenon of confusion between suitcases.

[0016] (3) The active bevel gear is driven to rotate by the dual-axis motor via the rotating shaft, which in turn drives the lead screw to rotate via the driven bevel gear. At this time, the nut pair slides down on the outer wall of the lead screw, causing one end of the nut pair to slide down on the inner side of the slide frame. This allows the nut pair to move down to the outer side of the bottom box via the lifting plate and the T-shaped frame driving the roller. This allows the suitcase to be moved and transported on the table or countertop, without the need for personnel to lift the suitcase. This achieves the purpose of easy and convenient transport of the suitcase. Attached Figure Description
