Solenoid Valve Hook Coupling for Fast Assembly and Stable Actuation

The coupling mechanism is divided into distinct functional elements: a coupling element with a recess on the mobile plunger and a coupling end with a protrusion on the rod. This segmentation allows for simple, quick assembly while maintaining reliable connection through the complementary geometric features.

The hooking coupling mechanism is designed to be self-aligning and self-locating through its geometric features (protrusion and recess). The components automatically guide themselves into the correct position during assembly, eliminating the need for complex alignment procedures or additional fastening operations.

The coupling features (protrusion and recess) are positioned on the lateral surface of the mobile plunger, utilizing the radial dimension rather than removing material from the axial face. This allows coupling to occur without interfering with the ferromagnetic material required for electromagnetic actuation.

The coupling elements are designed with specific geometric features (protrusion and recess) that provide sufficient mechanical engagement without requiring extensive material removal. The local geometry is optimized to achieve reliable coupling while preserving the bulk ferromagnetic material needed for electromagnetic forces.

The coupling mechanism merges the functions of connection, alignment, and positioning into a single integrated feature. The protrusion-c凹陷 combination simultaneously achieves all three functions, eliminating the need for separate alignment pins, adjustment mechanisms, or multiple fastening steps.

The hooking coupling design allows components to self-align and self-locate during assembly through their geometric features. The protrusion naturally guides into the recess, automatically establishing the correct relative position and orientation, which simplifies the assembly process while maintaining structural integrity.
