AI Technical Summary
Existing injection molded parts have various forms, but usually only provide one function. The replacement connection method is cumbersome, making it difficult to achieve multiple connections through a set of injection molded parts. The separate connection is easy to loosen, and there is a lack of a double locking structure that prevents misunderstanding, resulting in unstable locking.
An injection molded part with an inverted buckle structure is designed, including an injection molded comb and an injection molded female buckle. Both are equipped with a hand-rubbing auxiliary structure and a connection inverted buckle, and a fixed connection is achieved through the connection inverted buckle; at the same time, a T-shaped injection molded part and a control contact block are provided to provide multiple connection methods and anti-loosening structure.
The choice of multiple connection methods is realized. Through bolt positioning and friction locking of T-shaped injection molded parts, the stability and removability of the connection are ensured, and the looseness of the individual connection is avoided.
