Description

Technical Field

[0001] This utility model relates to the field of trolley case technology, and in particular to a modular environmentally friendly portable trolley case for waste sorting. Background Technology

[0002] The environmentally friendly waste sorting suitcase is an innovative waste sorting tool designed to facilitate waste sorting for residents while improving its efficiency and accuracy. This uniquely designed suitcase typically features multiple compartments, each clearly labeled with waste sorting categories such as recyclables, hazardous waste, wet waste, and dry waste. To use it, residents simply place different types of waste into the corresponding compartments, then zip up the suitcase or fasten the lock to easily carry it to the waste sorting point. The suitcase's design not only makes it easy to carry but also effectively prevents waste from scattering or becoming mixed up during transportation, thus improving the accuracy and efficiency of waste sorting.

[0003] The following problems exist: The internal design of common environmentally friendly waste sorting suitcases is often limited to using dividers for simple waste sorting. While this method can help people distinguish different types of waste to some extent, it is inconvenient when emptying the suitcase. When it is time to empty the suitcase, the user must manually open the suitcase and carefully remove or move the dividers to empty the waste smoothly. This process is not only time-consuming, but may also cause all sorted waste to scatter during the operation, thus increasing the difficulty of cleaning. Secondly, due to the presence of dividers, waste may get stuck when emptying, causing some waste to be unable to be poured out smoothly, requiring the user to repeatedly adjust the position of the dividers, which undoubtedly increases the complexity of emptying the waste.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) The outer wall of the first nut can slide on the inner wall of the first through hole, so that the bottom box can be pulled out to both sides, making it convenient for users to dump garbage. After removing the first nut, the bottom box can be disassembled. By setting a drawer, small items such as garbage bags can be stored. By setting the connection structure between the second threaded rod and the second nut, the top box can be fixed on both sides of the outer wall of the second upright plate. After removing the second nut, the top box can be disassembled. By setting the connection structure between the sliding rod and the hollow side plate, it is convenient for users to adjust the height of the lifting rod structure. Users do not need to bend over to use the suitcase, making the experience more convenient and comfortable. By setting multiple sets of bottom box and top box structures, it is not only convenient for users to classify and dump garbage, but also improves the overall efficiency of the suitcase.

[0021] (2) By setting the connection structure between the press-lock and the locking block, the lid can be fixed. When the user presses the press-lock with his finger, the locking block will automatically pop out from the press-lock. At this time, the user can pinch the lifting plate and lift the lid directly. Then the user can dump the garbage into the top box. By setting the connection structure between the insertion rod, the insertion hole and the insertion tube, the height adjustment of the lifting rod can be fixed. At the same time, pushing the two sets of lifting plates in opposite directions can make the two sets of insertion rods disengage from the insertion hole at the same time. Then the height of the lifting rod can be adjusted. Attached Figure Description
