[0002] Flexible waterproof casing is a hardware fitting suitable for the place where the pipe passes through the wall and is subject to vibration or has strict waterproofing requirements. If the wall where the flexible waterproof casing passes through is not concrete, it should be replaced with a concrete wall, and the casing must be solidified in the wall at one time. Flexible waterproof casing is widely used in construction, chemical, steel, tap water, sewage treatment and other units.

Through the arrangement of impact-resistant plates and springs, when the sleeve body is impacted by external force, the springs and impact-resistant plates can be used to buffer the impact, thereby reducing the easy damage of the sleeve body by external force. The purpose is to solve the problem and improve the practical value through this technology. Utility Model Content
