[0002] Plastic drums are widely used for the storage and transportation of various liquids. They have excellent properties for packaging special hazardous materials, such as being unbreakable, rust-free, and lightweight.

This utility model has a reasonable structural design. A spring force gauge is installed on the support rod on the right side. The first slide rail on the top plate allows for testing the tensile strength of the plastic bucket using the spring force gauge during sliding. It is easy to operate and has a wide range of applications. The utility model also has a compact structural design. An electric push rod is fixed to the top plate, and a pressure sensor is installed at the bottom of the electric push rod to detect the compressive strength of the bottom of the plastic bucket. The parameters are relatively accurate and have high reference value. However, existing plastic container strength testing devices lack automatic adjustment functions, requiring manual adjustment of the testing position during use, which affects testing efficiency. Therefore, we propose a plastic container strength testing device. Utility Model Content
