Abstract
Description
Technical Field
[0001] This utility model relates to the field of pallet technology, specifically a self-loading and unloading pallet for container houses. Background Technology
[0002] Currently, most modular container transport vehicles on the market are designed and operated for standard modular containers or container corner fittings. These vehicles generally use fixed interfaces, which are simple in structure but limited by the interfaces and transportation methods. In this pallet design, the pallet is used as an intermediate medium connecting the vehicle and the modular container, and a separate interface design is made for the structural characteristics of the GY5 modular container, which improves operational efficiency and saves labor costs.
[0003] However, existing pallets still have some problems in use:
[0004] The existing A-frame is simply attached to the fixed pole when it is fixed. However, it may come loose when walking, which may cause danger.
[0005] To address the aforementioned issues, an innovative design was implemented based on the existing pallet. Utility Model Content

One end of the sliding rod extends into the groove, and the other end of the sliding rod extends out of the groove. The end of the sliding rod extending into the groove is rotatably connected to the second rotating shaft.
[0011] The sliding rod extends to one end outside the groove and is sleeved with a sleeve rod. A limiting groove is opened at the top of the fixed rod. A limiting rod is slidably installed in the limiting groove. One end of the limiting rod extends into the limiting groove, and the other end of the limiting rod extends out of the limiting groove. The end of the limiting rod extending out of the limiting groove is fixedly connected to one side of the sleeve rod.
[0012] Preferably, the fixing rod is used to fix the "A" type frame.
