[0002] The lifting platform is a multifunctional lifting and loading and unloading mechanical equipment. The lifting platform is a commonly used lifting machinery for vertically transporting people or objects. It is often used for vertical transportation in logistics systems such as factories and automatic warehouses. In order to ensure safety during work, guardrails are usually set around the top of the lifting platform. Most of the existing lifting platform guardrails are fixed on the top of the platform and cannot be stored, occupying a large space. In addition, when placing items on the lifting platform, due to the existence of the guardrail, there are great limitations. For example, it is impossible to use a forklift to directly discharge the pallet loaded with items, and manual turnover is required, which is time-consuming and labor-intensive, and has low work efficiency.

[0003] Therefore, it is urgent to provide a guardrail mechanism for a lifting platform that can be stored. Utility Model Content
